Title: Automatic white balance device
Inventor: AZUMA EIICHIRO
IPC: H04N9/73
Filed: 1992-10-31
Abstract: PURPOSE:To suppress deviation in white balance at the time of high speed shuttering under the illumination of a flickering light source such as a fluorescent lamp. CONSTITUTION:A reply speed of a signal for gain control by a white balance amplifier section 6 is varied at a high speed by a control section 3 at high speed shuttering under the illumination of a flickering light source such as a fluorescent lamp.

Title: Secure method for generating password function output
Inventor: BERENZWEIG ADAM L
IPC: G06F7/58
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To protect the security of an identity recognition process used in a communication system. SOLUTION: Data showing the use of pseudo random function output is used for correcting at least one numerical value used for generating pseudo random function output. An output control signal supplied to a user identification module(UIM) device 60 is used as input to a pseudo random function processor 64. Outputs supplied by the processor differ according to whether output is to be stored in a key storage area or it is to be transferred for using it at a place except for UIM. Thus, security is protected by securely varying the transferred numerical value or the numerical value existing in the output of a UIM module from the numerical value stored in the UIM module as a key value.

Filed: 1994-12-21
Abstract: PURPOSE: To make an arm part to be the holding state by providing a 1st controller for controlling one arm part of a torsion spring against the direction falling out from an engaging hole and a 2nd controller for controlling the arm part in the 1st controlled state. CONSTITUTION: The torsion spring 28 is controlled against the direction falling out from the engaging hole 29c of a spring holder 29 by a control piece 29d of the spring holder 29 even in the state a main body part 29a of the spring holder 29 is tightly fitted against the fitting hole 27a of a pinion gear 27 making it unable to turn smoothly. Also, the torsion spring 28 is prevented from falling off from the spring holder 29 even though the spring holder 29 is rotated integrally with the pinion gear 27, since the torsion spring 28 is kept in the controlled state with the control piece 29d by a projecting part 29f for control on the spring holder 29. Consequently, opening parts 9, 10 in a shutter member 3 for recording/reproducing operation are not opened by stored elastic force of the torsion spring 28, and the entering of a dust is prevented.
