SHARP MOD. 12T-Q2 4xNORME YEAR 1968.

The SHARP MOD. 12T-Q2 4xNORME is a portable B/W television with multistandard capability.


Tuning is performed with drum selectors  a rotary turret for selectively connecting any one of a plurality of electrical circuit elements of like type but different constants in an electric circuit and particularly to a rotary turret selector of the multigang type. While the invention is of general application, it is particularly suitable for use as a selector to connect into the several stages of a high-frequency radio-frequency transmitter or receiver any of various frequency-determining circuit elements to adapt the apparatus to operate at any of a plurality of desired frequencies or frequency bands within a wide frequency range.
 Heretofore there have been proposed rotary turrets for selectively connecting inductors, capacitors, resistors or other electrical circuit elements into an electrical circuit. Such devices have the well-known advantage that the lengths and the configurations of the lead-conductors to all of the several circuit elements, as selected, are exactly the same so that the electrical constants of the circuit with each of the selectable elements connected therein is precisely predetermined. Such an arrangement also facilitates the alignment of a plurality of stages of a multi-band radio-frequency signal-translating circuit including frequency-determining elements selected by such a turret selector.

And the Transmission standard can be selected via front keyboard selection btw 819 and 625 CCIR standard types.

IS Quite rare for it's features and type, It's completely based on semiconductors and in a small space integrates all functions for a 4 Normes in a very compact way.

It was marketed mainly in FRANCE And GERMANY due to SECAM standard transmission broadcast.

Multi -standard Operation: Multi -standard sets were becoming more common even  with the international exchange of tapes and the interest in satellite TV. They must have switchable polarity at the vision detector, a sound section capable of handling a.m. or f.m. signals at four different carrier frequencies, and some means of decoding the three main colour systems. If you're content with monochrome reception all three sys- tems are to a degree compatible, provided you adjust the field hold and height on a UK set for 525-line/60Hz field .rate signals. Colour decoders that sort out PAL and SECAM already existed and more are on the way. Most of us have been used to the idea of PAL -only working for so long that a bit of information on the other two systems may not come amiss at this point. The chrominance subcarriers in the SECAM system - one for each colour -difference signal - were frequency modulated but remain in the area of .4.5MHz. Saturation is represented by frequency deviation. The two colour - difference signals Dr (red) and Db (blue) were transmitted on alternate lines, the decoder demodulators receiving their inputs directly and via a 64μsec delay line on alternate lines. Synchronised switching was required to ensure that the demodulators receive the correct signals. Since the subcarrier is present throughout the line there's no need for a crystal oscillator in the receiver. As with f.m. sound, pre emphasis was applied at the transmitter and de -emphasis at the receiver. There's a choice of ident signals, either an extended burst of Dr or Db during the back porch period or ten lines of triangular subcarrier, alternately Dr and Db, during the field blanking period. The unmodulated subcarrier present in monochrome parts of the picture showed as a "fuzzy" trace on oscilloscope waveforms. The NTSC system (USA, Japan, etc.) had a similar line frequency to ours but runs at 60 fields per second. The line period differs therefore and the vision bandwidth is narrower. The suppressed chrominance subcarrier wass phase/amplitude modulated as was in PAL, but without the phase change on alternate lines. The subcarrier frequency was around 3.58MHz, with a 9Hz burst on the back porch.

Sharp Corporation (, Shāpu Kabushiki-gaisha) is a Japanese multinational corporation that designs and manufactures electronic products. Headquartered in Abeno-ku, Osaka, Japan, Sharp employs more than 55,580 people worldwide as of June 2011. The company was founded in September 1912. It takes its name from one of its founder's first inventions, the Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa in 1915. Since then it has developed into one of the leading electronics companies in the world. It gained greater public awareness in the United Kingdom when it sponsored Manchester United F.C. from 1982 to 2000, which was a period of great success for the club.
Sharp took a controlling stake in Pioneer Corporation in 2007. On 25 June 2009, they agreed to form a joint venture with Pioneer on their optical business to be called "Pioneer Digital Design and Manufacturing Corporation".

History

In 1912, Tokuji Hayakawa  founded a metal workshop in Tokyo. The first of his many inventions was a snap buckle named 'Tokubijo'. Another of his major inventions was the Ever-Sharp mechanical pencil in 1915, from which the Sharp Corporation took its name.^] After the pencil business was destroyed by the 1923 Great Kantō earthquake, the company relocated to Osaka and began designing the first generation of Japanese radio sets. These went on sale in 1925. In 1953 Sharp started producing television sets.
In 1964 Sharp developed the world's first transistor calculator, which was priced at Yen 535,000 (US$1,400). It took Sharp several years to develop the product as they had no experience in making computing devices at the time. Two years later, in 1966 Sharp introduced its first IC calculator using 145 Mitsubishi-made bipolar ICs, priced at Yen 350,000 (about US$1000). Its first LSI calculator was introduced in 1969. This was the first pocketable calculator priced at less than Yen 100,000 (less than US$300), and turned out to be a bestseller.^[4]
Other notable achievements include the first LCD calculator in 1973. LCD technology continues to be a key part of Sharp's product range, in both the component and consumer-appliance sides of the business. Sharp shared a close working relationship with Nintendo during the 1980s, and was granted licensing rights for the manufacture and development of the C1 NES TV (1983, later released in North America as the Sharp Nintendo Television), the Twin Famicom (1986), the Sharp Famicom Titler (1989), and the SF-1 SNES TV (1990). All of these units are considered collectors items on the secondary market.
Sharp's Mobile Communications Division created the world's first commercial camera phone, the J-SH04, in Japan in 1997. In 2008 Sharp collaborated with Emblaze Mobile on the Monolith, "...an ambitious project to design the ultimate holistic mobile device".

Shaping the future with innovations – this has been Sharp's motto ever since it was founded in 1912. Like almost no other company, Sharp has made major contributions to technological development.

Sharp's roots date back to the year 1912. On 15 th September 1912, Mr Tokuji Hayakawa establishes a small metalworking shop in Tokyo . At that time already, innovations are a major key to success. Sharp's founder is granted his first patent at the age of 18 – for the "Tokubijo", a belt buckle. The business starts with 3 employees and a capital of a mere 50 yen.

Growth

Through innovative products and a solid business strategy, the small business expands continuously. In 1915 Mr Hayakawa invents the world's first mechanical retractable pencil – the “Ever Sharp Pencil”. The company's name is derived from this invention and the "Ever Sharp Pencil" stands for Sharp as a symbol of innovative power and pioneering spirit.

Sharp introduces "Quattron Technology" on their LE820 Series. As first in the industry, Sharp’s leading-edge liquid crystal technology has produced the revolutionary Quattron panel. It employs a four-colour filter that adds yellow (Y) to the three primary colours of red, green and blue (RGB), expanding the colour gamut and faithfully rendering nearly all colours that can be discerned with the unaided human eye, especially golden yellow. Combined with Sharp’s X-Gen panel that applies UV2A technology, the displays deliver an unprecedented high-quality picture as well as reduce energy consumption with an LED backlight.
