Abstract: PURPOSE:To perform arithmetic processing by using a method which represents both the positive and negative polarities of an analog value or many values with one light beam and its converted representation. CONSTITUTION:A light signal is represented with 1st polarized light (p polarized light) 4 and 1st polarized light (s polarized light) 5 which have orthogonal planes of polarization and when one direction of the two polarized light beams 4 and 5 is made to correspond to the positive value of the light signal, the other is made to correspond to the negative value of the light signal. Further, this light signal processor is equipped with a light source 1 which outputs 3rd polarized light whose intensity is modulated corresponding to the absolute value of the light signal and a spatial modulator 3 which inputs the 3rd polarized light, rotates the plane of polarization of the 3rd polarized light according to whether the light signal is positive or negative, and outputs two polarized light beams. Further, the light signal processor which processes plural light signals adds plural light signals for every two polarized light beams representing the light signals respectively and outputs a difference in added light intensity.

IPC: H02M3/155
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a circuit by which a current flowing via an inductor can be limited to a definite upper-limit value. SOLUTION: An input voltage to this switching regulator is given to a switch M1. The inductor L is installed across the switch M2 and an output terminal. A sense resistance Rs is connected in series with the inductor L in order to detect an inductor current.

Abstract: PROBLEM TO BE SOLVED: To provide the solid-state image pickup device with excellent image quality in which fixed pattern noise of each solid-state image pickup element is eliminated depending on an accurate temperature of each solid-state image pickup element itself.

A noise eliminating means 6 corrects an output by using the corrected data so as to eliminate fixed pattern noise of the solid- state image pickup element in response to an accurate temperature of the solid- state image pickup element itself even when the solid-state image pickup element 1 whose fixed pattern noise is changed with temperature.  Thus, an image without image quality deterioration due to the fixed pattern noise is obtained.

Title: Seismoscope
Inventor: TSUGII HIDESHI
IPC: G01H1/00
Filed: 1988-12-30
Abstract: PURPOSE:To eliminate the need to provide an automatic leveling mechanism and to realize a small-sized seismoscope which can be improved in response by swinging an actuator provided successively at the upper part of a cylindrical plunger with the impulsive force of the rolling movement of a spherical body accompanying a swing such as an earthquake and thus opening and closing a switch part. CONSTITUTION:When a case 1 vibrates owing to vibration such as an earthquake, a steel sphere 3 also vibrates, but the receiving surface 2 for the steel sphere 3 is in a circularly cone shape, so the vibration of the steel sphere 3 is less than the vibration of the case 1. Therefore, the steel sphere 3 does not abut on the cylindrical plunger part 4A of the plunger 4 until the vibration reaches a specific value. When the steel sphere 3 rolls and moves on the receiving surface 2 by the vibration which is larger than the specific value and abuts on the cylindrical plunger part 4A, the actuator 5 united with the plunger 4 swings around the local part of an annular engagement projection part 5C as a fulcrum R. A hemispherical engagement projection part 5D presses up a movable contact piece 11 by the swinging motion and the movable contact piece 11 abuts on a fixed contact 10 to close the switch part. Namely, the seismoscope operates.
