Title: Output buffer circuit
Inventor: SUZUKI YASUAKI
IPC: H03K19/0175
Filed: 1994-05-25
Abstract: PURPOSE:To reduce power consumption by speeding up level confirmation when a tri-state buffer is set to a high impedance state with respect to the output buffer circuit providing the output of a digital signal. CONSTITUTION:A tri-state buffer circuit 1 provides the output of an output signal OUT corresponding to an input signal IN or interrupts the output signal OUT to set a high output impedance based on the selection under the control of a control signal CONT. A pull-up resistor Rup or a pull-down Rdwn (not shown) 8 is connected between the output terminal of the tri-state buffer circuit 1 and a high potential power supply VDD or a low potential power supply GND, and when the control signal CONT is changed to designate a high impedance, a switch means 3 conducted for a prescribed time is connected in parallel with the pull-up resistor Rup or the pull-down Rdwn. When the tri-state buffer 1 is set to a high impedance, a stray capacitance C of an output line is charged or discharged via the switch means 3 to confirm the level of the output line at a high speed.

Title: Malfunction preventive circuit for cine camera
Inventor: TAKIMOTO HIROYUKI
IPC: G01R19/165
Filed: 1978-09-08
Abstract: PURPOSE: To prevent malfunction securely, by disabling the shooting control circuit only when the drop of power supply voltage continues over a specified duration.  
     CONSTITUTION: When the supply voltage drops, the comparator output inputting from a terminal I 3  is inverted to a high level, whereas the output of NOR gate NR 1  is inverted to a low level, so that a counter 2 is reset. As a result, the counter 2 counts the number of clocks generated from an oscillator OSC, and the counting reaches a specified value after the lapse of a specified duration, a flip-flop FF 1  is reset. By this reset output of FF 1 , a diode for supply voltage display, etc. are lit. When the shutter is opened, after controlling only the closing of the shutter, a power supply to the control circuit is cut off. Therefore, in the case of temporary drop of supply voltage, the FFFF 1  keeps the set state, and the control sequence does not stop. Only in the case of continuity of drop of supply voltage over the specified duration, the control circuit is made inactive corresponding to the shutter release state, so that malfunction may be securely prevented.

Title: Color camera
Inventor: SHIMIZU TOMIO
IPC: H04N9/04
Filed: 1984-05-31
Abstract: PURPOSE:To perform color temperature compensation with high precision by inputting the output of an external sensor to the control input terminal of a color gain control circuit through a circuit which corrects the spectral characteristic of an image pickup device. CONSTITUTION:When an image of a white subject is picked up and the color temperature of a light source is varied, control characteristics of an R-ch gain control circuit 4 and a B-ch gain control circuit 5 are so determined as shown by solid lines in a graph so that white is represented with an NTSC output 11 obtained through the signal processing of the camera. On the other hand, signals outputted from the external light sensor 12 through an inverting amplifier 13 and a noninverting amplifier 14 are not coincident with each other as shown by broken lines because of a difference in the spectral characteristic between the image pickup device 1 and sensor 12. The characteristic shown by the broken lines is corrected as shown by arrows through gamma circuits 15 and 16 and de- gamma circuits 17 and 18 to make a white balance adjustment in case of variation in the color temperature of the light source.

Filed: 1992-04-30
Abstract: PURPOSE:To minimize the propagation of errors due to spike noise by removing fluctuation due to AC coupling from reproducing signals and by obtaining enve lope slice signals in which the influence of the spike noise is controlled. CONSTITUTION:Based on the reproducing signals inputted, and by a means for generating reference transient signals (consisting of a reference gate generating circuit 4, operational amplifiers 10, R4, R5, C2, R6, and an operational amplifier 11) using as a reference the mark detection signals C detected by a mark detection circuit 3, the reference transient signals having a transient characteristic in equal value to the AC coupling of the reproducing signals are generated.

Abstract: PURPOSE:To prevent such defectiveness as to blow offensive odor into a cabin by cooling a dehumidifying means to the specified temperature when an environmental condition of enabling the stop of control on the dehumidifying means for dehumidifying blast air into the cabin by cooling is materialized and the cooling stop state of the dehumidifying means has continued for the specified time or more. CONSTITUTION:In an air conditioner for an automobile, an evaporator 6, a dehumidifying means, forms a part of a refrigerating cycle 7 for cooling the air, fed from a blower, to feed it downstream. At the time of defogging operation performed by the refrigerating cycle 7, when the cabin internal humidity becomes the fog limit internal humidity to the outside air temperature, a compressor 8 is driven so as to obtain the required after-evaporateion temperature. When a condition of enabling the stop of the compressor 8 is materialized and the cooling stop state has continued for the specified time or more, the required after-evaporation temperature is set to drive the compressor 8. The air passing through the evaporator 6 controlled to the set low temperature is thereby cooled effectively so as to prevent the generation of offensive odor.
