Title: Solid-state image pickup device, its drive method and camera using the solid-state image pickup device
Inventor: TANAKA HIROAKI
IPC: H04N5/3728
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To suppress blooming and smear components in an output signal and to reduce a screen size by applying a charge sweep-out pulse to an image pickup element board for all horizontal blanking periods for one vertical synchronization period after light reception. SOLUTION: A shutter pulse SP is generated by a timing generating circuit 21 as a charge sweep-out pulse for all horizontal blanking periods for one vertical synchronization period after light reception and the charge sweep-out pulse is fed to a board 17 while superimposing a board bias Vsub with the shutter pulse SP. Thus, the period when the signal charge is stored in the sensor section 11 is only one horizontal scanning period (1H) and even when an excess light is made incident onto the sensor section 11, since the period to store the signal charge is short, the signal charges generated in the sensor section 11 are not excessive. As a result, even in the case of incidence of excess light, the signal charges are not overflowed to surrounding picture elements and a blooming component is suppressed.

Title: High pressure discharge lamp
Inventor: SAITOU MASATO
IPC: H01J61/16
Filed: 1980-11-19
Abstract: PURPOSE:To improve the required time of discharge start and glow discharge duration and make the life of a discharge lamp long by using Ne-Ar-Kr mixing gas as starting rare gas and specifying the mixing ratio of Ne to the mixing gas. CONSTITUTION:The mixing ratio of Ne to mixing gas is 50-99.8% by sealing the mixing gas consisting of Ne-Ar-Kr as the starting rare gas of a high pressure lamp in which mercury is sealed. Since the optimum Pd value is reduced by adding this Kr, the discharge of auxiliary discharge is easily collected on the specified location of a main electrode and the transition of glow into arc is facilitated. Besides, there is a Penning effect between Ne and Kr. Even in an area where Ar+Kr ratio is high, the required time of discharge start can be reduced by the Penning effect.

Abstract: PURPOSE:To confirm easily an error correcting and checking function, and to execute a patrol effectively, by rewriting a diagnostic signal together with a data signal in a main storage device, instead of an error correcting and checking signal of a read-out data from the main storage device. CONSTITUTION:At the time of a patrol, a part of a write data from a CPU 1 is used for controlling the patrol, a controlling circuit 22 is controlled by its controlling bit, a data read out of a main storage device 3 and an error correcting and checking ECC signal are checked by an ECC circuit 21, and the corrected read-out data and ECC code are rewritten in the device 3 as a write data ECC code.
