Patent JP-H02119381-A (JP)
Title: Black level correction circuit
Inventor: KUBOTA AKIHIKO
IPC: H04N5/57
Filed: 1988-10-28
Abstract: PURPOSE:To enable flare correction even in a simple image pickup device by shifting a pedestal level of a video signal to a black level when luminous quantity is much and shifting the pedestal level to a white level when the luminous quantity is less. CONSTITUTION:When a luminous quantity is more than that at an iris open point, since an AGC control potential Vc is high, the base potential of a transistor(TR) 17 is high and a potential at a common connection point of emitters of TRs 16, 17 is high. Thus, the clip level of a video signal fed to a base of the TR 16 is increased and the blanking pulse added to the video signal is largely eliminated. As a result, the pedestal level of the video signal outputted to an output terminal 18 is lowered, and the pedestal level is shifted forcibly toward the black level. Thus, the decrease in the contrast due to flare is suppressed to obtain a stereoscopic picture. That is, the clip processing of a differential amplifier circuit is utilized and the pedestal level of the video signal is shifted toward the black level or white level in response to the luminous quantity of an object.

Title: Semiconductor manufacturing apparatus
Inventor: MIYAJI TSUKASA
IPC: H01L21/68
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To make severe control needless on a lift drive source, enable the stable contact of metal lift pins to a semiconductor wafer back side and make little influence of the deposit of a reaction product by connecting the metal lift pins with the lift drive source through metal springs. SOLUTION: A metal lift pin 3 is connected to a lift drive source 4 through a metal spring 5. After ending a plasma process, the metal lift pin 3 is lifted to contact the back side of a semiconductor wafer 1 by driving the lift drive source 4 to destaticize the semiconductor wafer 1 supported on an electrostatic shuck stage 2 wherein the lift-up length of the metal lift pin 3 is set to about 1.0 mm from the electrostatic chuck stage 2 surface, because, if too long, the lift-up of the metal lift pin 3 breaks the semiconductor wafer. Thus the destaticization is made along a route from the metal lift pin 3 to the lift drive source through the metal spring and hence the influence of the deposit of a reaction product is made little.

Title: Picture reader
Inventor: ARAKAWA TOKUO
IPC: H04N5/335
Filed: 1987-10-27
Abstract: PURPOSE:To facilitate the correction of a dark voltage by adopting the constitu tion such that a dark voltage signal read by a pre-operation is subtracted analog ically at the pre-stage of a log converter. CONSTITUTION:In shutting a light of a light source in the pre-operation, a dark voltage is generated. Since an inverting input of an analog subtractor 2 is connected to GND, the dark power output of a photoelectric conversion section 1 is stored in a dark voltage storage circuit 5. In entering the read of an original, a control signal (b) of a control circuit 7 switches the connection of analog switches 8, 10 and a selector 9. An original picture signal from the conversion section 1 is given to a noninverting input of the subtractor 2. After a digital dark voltage signal read from the circuit 5 is D/A-converted (7) in this way, the signal is fed to the inverting input of the subtractor 2 via the switch 10. Thus, the dark voltage is subtracted from the original picture signal by the subtractor 2. The picture signal whose dark voltage is corrected is fed to a log converter 3, becomes a density proportional signal, subject to A/D conversion 4 and outputted (11) via the selector 9. Thus, the dark voltage is corrected easily.

Filed: 1985-12-04
Abstract: PURPOSE:To optionally change the display pattern of a variable pattern display device, by changing attachable/detachable small-capacity memory modules from the outside when a display pattern is fixedly stored in a memory in advance. CONSTITUTION:Upon receiving an incoming call through a telephone set, a microprocessor 2 refers to the pattern tables of connected modules among exter nal memory modules 1-n and causes signals from a sound source to make a loudspeaker 3 produce sounds by controlling a switch driver 4 in accordance with the patterns of the tables. Since several kinds of patterns are usually indicated on the exchange side in the case of a private telephone set connected with a PBX, etc., depending upon the kind of a call, a display controlling signal contains a pattern number in addition to ON/OFF. In this case, patterns are written in the tables in accordance with pattern numbers in the modules also and the microprocessor 2 can produce several kinds of patterns from the pattern information. Therefore, when memory modules connected with the same display device are exchanged, appropriate patterns can be displayed. Accordingly, selec tion of an optional pattern becomes easy and the serviceability is also improved.
