Abstract: PURPOSE: To secure the faithful reproduction of the picture as well as to realize a high-efficiency transmission of signals by drawing out the prescribed black picture element and white picture element deciding patterns and then delivering the each divided picture element after dividing it into four equal parts.  
     CONSTITUTION: The sampling information SGi obtained through the sensor is memorized in memory 1 to be then read out, and the predictive value is memorized in memory 2 for the non-sampling picture element averaged at average value arithmetic circuit 3. The output picture element density signal of memory 1 or 2 is quantized by level recorder 4 to be delivered to pattern memory 5. Memory 5 holds the signal as the address to memorize information 1 and 0 divided into four equal parts. Thus the information of each picture element is delivered via memory 5 in the form of output signal SGO divided into four equal parts. In such way, the prescribed black and white picture element patterns are drawn out and then divided into the square grid form, and each element is delivered through division into four equal parts. As a result, the faithful restored picture is obtained, at the same time realizing a high-efficiency signal transmission.

Title: Black chrome plating bath
Inventor: TAKAHASHI TSUTOMU
IPC: C25D3/08
Filed: 1977-11-17
Abstract: PURPOSE: To obtain an excellent plating covering a wide temperature range and a wide current density range by adding of an alkali and silicofluoric acid or a silicofluovide compound and nitric acid to a plating both at a proper ratio.  
     CONSTITUTION: A black chrome plating liquid is prepared containing 200 to 700 g per 1l of chromic and anhydride which does not contain sulfuric acid, 10 to 100 g of alkali (sodium hydroxide), 0.2 to 1.5 g of a silicofluovide acid or silicofluovide compound, 0.5 to 10 g of nitric acid or nitrate. The addition of slilcofluovide acid or silicofluovide compound to the plating bath can facilitate the separation of chrome oxide thereby expanding the current density range of producing black plating. This allows production of a black plating at a normal temperature at a cathode current density 2 to 3A/dm 2 . Thus, a high current efficiency of about 10 percent is available at a chathode current density of 30 to 40A/cm 2 . In addition, the current efficiency increases with the increase in the electrolysis time.
