Title: Photoelectric transducer
Inventor: KIZU SHIYUUJI
IPC: G06K9/20
Filed: 1979-11-28
Abstract: PURPOSE: To prevent the malformation or discoloration of the object to be read which is caused by the heat rays, by providing the infrared-ray cutting filter which transmits only the spectral sensitivity property component of the photodetector among the near infrared rays emitted from the illuminating light source.  
     CONSTITUTION: The mail 2 is illuminated by the illuminating optical system 6 consisting of the illuminating light source 4 and the reflector 5, and the reflected light from the cellophane paper on the mail 2 is received by the receiving optical system 9 consisting of the photodetector 8. In such constitution, the infrared-ray cutting filter 10 is provided in front of the light source 4. The filter 10 transmits only the wavelengths of about 600W1,000mm. In general, the brown or orange envlope, a colored envelope with a window, shows the reflection factor nearly same as a white envelope at about 600W700mm. Accordingly, the same level is obtained for the background value of each envelope with use of the filter 10, and thus the slice level can be decided easily in case the output signal is quantized. Furthermore, the heat rays delivered from the source 4 can be virtually eliminated.

Title: Complementary mos logic circuit
Inventor: ARAKI TOSHIYUKI
IPC: H03K23/00
Filed: 1978-12-15
Abstract: PURPOSE:To realize a logic circuit featuring a high-speed transition time as well as a small occupied chip area by securing the vertical connection between one unit of P-channel MOSFET and N-units of N-channel MOSFET. CONSTITUTION:Gate Q of each MOSFET is connected to the flip-flop of the N- notation. For example, if set side terminals Q3, Q4 and Q5 feature the high voltage, the high voltage is applied to the gates of PMOSFET25 plus NMOSFET26, 27 and 28 each. As a result, FET25 is off with FET26, 27 and 28 turned on respectively. At the same time, output connection point 33 features the low voltage, and FET26 is turned on. At the time during which output point 34 transfers, NMOSFET22, 23 and 24 are turned on. After this, PMOSFET29 and 30 are turned on, and this time is proportional to the chip size of MOSFET. In this connection, the overall chip size is reduced since the number of chips is small for the structure FET.
