Title: Semiconductor integrated circuit device
Inventor: HABUKA TOSHITO
IPC: H01L23/52
Filed: 1980-11-14
Abstract: PURPOSE:To reduce noise to be generated by an electric interference in a semiconductor integrated circuit device by a method wherein a pair of signal lines having opposite phase with each other, or a pair of twisted type signal lines, or a differential amplifier is used for a signal line of the semicoductor integrated circuit device. CONSTITUTION:When the second signal line B0 receives the electric interference from the first signal line A1, the third signal line A2 is arranged in parallel with the first signal line A1 between the first signal line A1 and the second signal line B0, and signals having opposite phase with each other are transmitted in the signal lines A1, A2. When the signal lines A1, A2 are made to approach extremely, and the distances to the second signal line B0 can be considered as almost the same, because a pair of the signal lines A1, A2 have opposite phase with each other, fluctuations of voltage and current to the signal line B0 are cancelled out with each other, the signal line B0 can get rid of the interference. Besides, a means to form the signal lines A1, A2 in a twisted type, etc., may be used.

Filed: 1989-06-22
Abstract: PURPOSE:To prevent mis-detection of reflected light or the like by other photoelectric switch by generating random pulse modulation light from a light emitting element at random or at an optional time, and detecting a pulse only among photodetector pulses synchronously with the light emission pulse of its own light emitting element. CONSTITUTION:A pulse generating circuit 10 outputs a light emitting pulse modulation signal (d) including a light emitting pulse generated at random or with a random period at an optional time to a driving circuit 11 and a pulse confirming circuit 14. The circuit 11 stimulates a light emitting element 12 when a light emission pulse of the light emitting modulation signal (d) is at an H level, and a light receiving element 13 receives the light from the light emitting element 12. The pulse confirming circuit 14 outputs an output signal (e) confirming it that a light receiving pulse resulting from converting received light into an electric signal and the light emitting pulse of the light emitting modulation signal (d) are synchronized for a prescribed number of times to an output circuit 15. Thus, accurate object detection is attained without malfunction due to the reflected light from other photoelectric switch or noise such as external disturbance light.

Title: Digital phase control circuit
Inventor: MIYAHARA YOUJIROU
IPC: H02M7/155
Filed: 1983-09-02
Abstract: PURPOSE:To generate an output pulse in response to a control signal at a high speed without a pulse phase defect even if the variation in the step of the control signal becomes 60 deg. or larger by providing a pulse defective phase preventing circuit in a phase control circuit. CONSTITUTION:When a control signal is abruptly varied, the output A of a comparator becomes H level, and produced through a NAND43 and a one shot circuit 51 of a pulse interlock circuit 40. Thus, a ring counter operates to switch to next phase, but since the control input is still low, the output of the comparator becomes H level. Here, a delay circuit 53 is set by the rise of the input C, and outputted through a one shot circuit 54 after the prescribed time Td is elapsed. As a result, two pulses H are inputted to a ring counter, the phase is sequentially varied in the ring counter, and the phase of the pulse is not become defective.

Title: Color balance adjusting device of photographic negative plate and photographic printing control device applying said device
Inventor: HOSOZUMI MOTOJI
IPC: G03B27/73
Filed: 1979-12-11
Abstract: PURPOSE: To enable the color balance and lightness of television images to be easily adjusted by using an adjusting light source which permits adjustment of the color balance of the luminance of light.  
     CONSTITUTION: Three light source electric bulbs 13 are disposed to a light source part 11 and separation-addition filters 17W19 are disposed thereto; in addition, dimming devices 10 and potentiometers 14 are mounted respectively thereto. If with this constitution the regulating potentiometer 14a is moved, the emitter potential of a UJT transistor rises via a PNP transistor, causing the UJT TR to conduct, then a gate pulse is applied to a TRIAC which controls the supply of AC power source applied to the light source bulbs 13. This causes the period of the power supply to change and finally the luminances of the light source bulbs change. Hence, according to this luminance, the luminances of blue, green and red change. Thereby, the images adequate for an image receiver may be obtained by adjusting the light sources.

Title: Drive circuit of fet output switch
Inventor: OYA MASAYOSHI
IPC: H02M3/28
Filed: 1994-06-20
Abstract: PURPOSE:To prevent thermal breakdown of an output semiconductor switch in the case the switch is turned off when a load short-circuits or at output dropping time by connecting a diode and capacitor to one end of the output winding of a main transformer and sending a control signal to an FET gate from the positive polarity of the capacitor. CONSTITUTION:A switch 10 controls so that the gate voltage of an FET 9 for output switch can be stably supplied by means of a diode 12 and capacitor 13 even when a load short-circuits in a state where the FET 9 is turned on. Therefore, the FET 9 can be maintained in a turned-on state. Even when output drop occurs, the FET 9 can be operated in a saturated area and the abrupt temperature rise of the FET can be avoided, since the gate voltage can be secured in the same state. Therefore, the FET output switch 9 can be protected.
