Title: Driving system for charge injecting device
Inventor: YAMAMOTO TOSHIROU
IPC: H04N5/335
Filed: 1981-07-24
Abstract: PURPOSE:To prevent the insulation breakdown of insulation film at a crossover part of an electrode, by controlling a storage electrode voltage of a charge injecting device with a voltage controlling means in response to a high voltage produced at a detection electrode at malfunction of a charge amplifier. CONSTITUTION:If a charge amplifier is caused with latch-up, it is detected at a discriminating means 42 and a control voltage Vc of a line (d) is brought into (0). Thus, MOSFETs Q4, Q7, and Q10 are turned on. Since the gate voltages of MOSFETs Q6, Q9 and Q12 are at the same potential as a line (c), these are turned off and a voltage of bus lines Y1-Y3 keeps (0) with a scanning pulse of a vertical direction shift register. Then, even if latch-up is caused and the potential of detection electrodes and successive X bus line is increased from (0) to (+12)V, since the potential of a storage electrode and successive Y bus is zero, the insulation breakdown of the insulation film can be avoided.

Title: Amplifier
Inventor: SOBASHIMA AKIRA
IPC: H03F3/345
Filed: 1981-07-24
Abstract: PURPOSE:To stabilize a voltage between the gate and the source, by controlling a variable impedance element connected to the source of an FET with an output of a DC inverting amplifier connected to the source of the FET. CONSTITUTION:A source of an FET13 is connected to a negative input terminal of a differential amplifier 22, and a capacitor 21 is connected between the inverting input terminal of the amplifier 22 and the output terminal, and the output terminal is connected to a transistor (TR) 15 as a variable impedance element 15. When the source potential of the FET13 is risen, the output of the amplifier 22 is decreased and the current of the TR15 is increased so that the source potential of the FET13 can be decreased. Thus, since the FET can be operated at a saturated drain current with the potential between the source and the gate kept to zero potential, low noise characteristics can be attained.

Filed: 1989-05-11
Abstract: PURPOSE:To facilitate the self-check of a ROM by calculating the reliability confirmation value after initialization of a confirmation value store area and a complement store area and storing the reliability confirmation value and its complement into the confirmation value area and the complement store area respectively. CONSTITUTION:A specific address of a ROM110 is defined as a confirmation value store area and initialized with an optional number like '00(H)', etc. At the same time, a complement store area is initialized with a complement, e.g., 'FF(H)' of the value stored in the confirmation value area. Then the reliability confirmation value of the ROM110 is obtained and the complement of the reliability confirmation value is obtained. Then the reliability conformation value and its complement are stored in the confirmation value store area and the complement store area respectively. Therefore the coincidence is secured between the reliability confirmation value calculated before storage of the reliability confirmation value into the ROM110 and that calculated after astorage of the reliability confirmation value. As a result, the self-check is facilitated for a product ROM.

Title: Reflectance measuring apparatus
Inventor: ANDO OSAMU
IPC: G01N21/47
Filed: 1994-05-31
Abstract: PURPOSE:To carry out measurement for an unknown specimen while the incident angle of luminous fluxes to be measured being set correctly by setting an optical axis correctly by using an adjusting mark having a small hole and a reflection standard mirror before the measurement. CONSTITUTION:An adjusting mark 24 having a small hole 25 is set at a prescribed position in a reflecting optical measuring system 10. At that time, positioning is so carried out by moving the whole body of the reflecting optical measuring system 10 as to make the luminous fluxes to be measured pass the small hole 25. Meanwhile, a reflection standard mirror 21 is set at a position at which a specimen is to be installed. That is, if the angle between the specimen standard face 14 and the impinging light is 30 degrees, the reflection angle of the reflection standard mirror 21 is set precisely at 30 degrees. If there is difference, the reflected light comes out of the impinging light route and impinges against a wall face of the adjusting mark 24 without passing the small hole 25. Consequently, the incident angle of the light to the specimen can be corrected precisely by positioning the reflecting optical measuring system 10 while observing the reflected light of the wall face of the adjusting mark 24.
