Title: Semiconductor acceleration sensor
Inventor: SUZUKI YOSHIHISA
IPC: G01P15/18
Filed: 1990-11-01
Abstract: PURPOSE:To enable the detection of three-dimensional acceleration at a high sensitivity with a small device by connecting a central thick part, a medium thick part and a medium thick part surrounding it at a specified interval and a peripheral thick part surrounding them at a specified interval with thin support parts separately. CONSTITUTION:For example, acceleration is applied in a direction (x), an inertial force works on a central thick part 5 and a medium thick part 6. As a (z) axis-wise deviation l is caused between a center of gravity G of the thick part 5 and thin support parts 9 and 11, a compression stress works on the support part 9 more with an access to a peripheral thick part 7 while a tension stress works thereon more with an access to the thick part 6. The compression stress and the tension stress work on the support part 11 in a full opposition to each other. So, a difference is determined between outputs of bridge circuits made up of strain gauges 2 and 4 as provided respectively on the support parts 9 and 11 to detect an electrical signal corresponding to acceleration working in the direction (x). Likewise, the acceleration working in the direction (y) is determined by measuring a difference of a stress working on thin support parts 8 and 10 as caused by an inertial force working on the thick part 5 with the strain gauges 1 and 3 to detect an electrical signal corresponding to the acceleration.

Abstract: PROBLEM TO BE SOLVED: To improve the recording density of optical disk by offsetting the aberrations of an optical system and converging the spot size of a light beam down to the theoretical threshold by using a phase conjugation optical system. SOLUTION: In the optical pickup device for recording and reproducing information on and from an optical disk 8 by condensing the light beam to the beam spot on an optical disk plate 8, a light beam emitted from the laser diode 1 is shaped down to the spot size of the light beam required on the optical disk plate 8 by a pinhole. The optical path is bent at a prescribed angle by reflection with a polarization beam splitter 5 and thereafter, the light beam is polarized to be a circularly polarized light by a first quarter-wave plate. This light is made incident on the phase conjugation optical medium 13 excited by the light of the wavelength equal to the wavelength of a laser diode beam.  The phase conjugation light emitted from the phase conjugation optical medium 13 is converged onto the optical disk plate 8 through the polarization beam splitter 5 and two pieces of the quarter-wave plates 6, 12.

Title: Magnetic sensor
Inventor: MOTOKAWA MASARU
IPC: H01L43/08
Filed: 1986-12-10
Abstract: PURPOSE:To detect the passing speed of a body to be detected as the number of pulses by applying the output of an AC power source to four ferroelectric thin film resistance elements and amplifying the differential output between the mid-points of the four ferroelectric thin film resistance elements. CONSTITUTION:A magnetic sensor is so arranged that an MR element 2a and an MR element 2b vary in resistance value differently in a uniform magnetic field H. An MR element 2c and an MR element 2d are so arranged as to vary in resistance reversely to the MR elements 2a and 2b, and connected in series and also connected to the AC power source 1. Further, the difference between mid-point potentials of the MR elements 2a-2d is amplified by an amplifier 3 to obtain an output Vout1. In this structure, the output Vout1 of the magnetic sensor varies repeatedly in the order of Lo, Hi, Lo-Lo according to the passing speed of a magnet 5 as a body to be detected. For the purpose, the number of pulses is counted to convert the passing speed of the body to be detected into the number of pulses.

Title: Random data extraction method in communication system using multi-channel access system
Inventor: ISHII YOSHITOMO
IPC: H04W84/08
Filed: 1990-10-30
Abstract: PURPOSE:To attain quick multi-channel access(MCA) processing by using a received noise signal for an initial data given to a random number generator in the case of the MCA processing. CONSTITUTION:A cordless telephone system consists of a controller 2 connecting to a trunk line 1, plural connectors (fixed devices and master sets) 3 in pairs, and plural sets comprising cordless telephone sets (mobile sets and slave sets) 4. In the case of implementing the MCA processing, a received noise signal is used for a randomizing and initializing data for discriminating an idle talking channel.

IPC: G03B21/00
Filed: 1991-11-11
Abstract: PURPOSE:To automatically adjust a focus without sacrificing the brightness of a projected image by inserting an optical means for detecting a focus in an image projection optical system only when the focus is detected. CONSTITUTION:A light beam emitted from a light projection part 5 in order to detect the focus is guided to a projection lens 3 by a quick return system half mirror 10 arranged just before the lens 3 and projected on the screen together with the projected image. Besides, it is returned to a light receiving part 5 through an identical optical path. The mirror 10 is controlled by an electric control circuit and inserted into the optical path of the projected image in a moment when the switch of a light source is turned on, when the zooming of the lens 3 is executed and when a fixed time passes after the focus is detected last time. Then, range-finding is executed. Therefore, a time that the mirror 10 is inserted into the optical path is shorter than a time that one screen is operated. Besides, the loss of the light quantity of the projected image is little.

IPC: B60H1/00
Filed: 1989-11-15
Abstract: PURPOSE:To approximate the value of the outside air temperature to the true outside air temperature, even at the time of low speed traveling, for enhancing detection accuracy by using the detected temperature obtained before the detected vehicle speed becomes lower than a reference vehicle speed as the outside air temperature, when the detected vehicle speed is less than the reference vehicle speed. CONSTITUTION:Respective detection signals 3a, 5a, 7a from an ignition sensor 3, a vehicle speed sensor 5, and an outside air temperature sensor 7 are input into a control unit 1, and these signals are processed by a arithmetic circuit 13 respectively. In other words, the arithmetic circuit 13 judges the detection temperature, for example, in accordance with the detected outside air temperature 7a, and successively stores the information related to this in a memory circuit 15. When the detected vehicle speed is less than a reference vehicle speed, the information related to the detected temperature stored directly before the detected speed becomes lower than the reference vehicle speed is taken out form the memory circuit 15 for outputting it to a display part 17 and to a control circuit 19. Thus, the outside air temperature is displayed, and also various temperature controls are executed.
