Inventor: GO MITSURU
IPC: H01H13/20
Filed: 1988-04-26
Abstract: PURPOSE: To simplify the structure by providing a spring piece, which is formed with a fixed contact and a movable contact, in an insulating board, which is formed with an output conductive path and an input conductive path, and furthermore, providing a push body for pushing the spring piece to the insulating board for contact. CONSTITUTION: A spring piece 1 is fixed onto an output conductive path 6 of an insulating board 5 by four fixed contacts 2 so as to have electrical continuity, and while the whole of the spring 1 is fixed to the insulating board 5 so as to be supported. At this stage, since movable contacts 3, 3 are formed short so that they do not contact with an input conductive path 7 provided under the movable contacts, electrical continuity is not generated between an input lead 8 and an output lead 9.  Continuously, when a push body 10 is pushed down from over, the spring piece 1 is elastically deformed, and the movable contacts 3, 3 contact with the input conductive path 7 so as to electrically continue the input lead 8 and the output lead 9 to each other, and while a stopper 4 abuts on the input conductive path 7 so as to generate the sound, and with this sound, a condition that the contact is surely closed is confirmed. Structure is thereby simplified.

Title: Control device of automatic transmission
Inventor: TAGA YUTAKA
IPC: B60W10/10
Filed: 1991-04-09
Abstract: PURPOSE:To improve the durability of a friction engaging device. CONSTITUTION:An automatic transmission 3 is controlled by a control device 1 which has a torque reduction means 4 to reduce the input torque or a torque transmitted to a specific gear train when a rearward step is set. This control device 1 is furnished with a torque reduction impossibility detecting means 6 to detect that the torque reduction control by the torque reduction means 4 is impossible, and a rearward step prohibiting means 7, and when the torque reduction control is impossible, such as the torque reduction is made impossible when the rearward step is selected, it is prohibited to set the rearward step. As a result, since the rearward step which is the largest reduction ratio is not set, an excessive torque is not applied to a friction engaging device 2, and an excessive sliding is not generated resulting from that. And the durability of the friction engaging device 2 is improved.

Abstract: PURPOSE:To make a device small-sized and light-weight by constituting the device of a movement detecting mechanism and an input selecting mechanism and providing plural sets of acceleration sensors, two-stage integrators, binarizers, operation reset switches for integrators as the movement detecting mechanism. CONSTITUTION:When a mouse is moved from the left to the right and from the right to the left, the output of an acceleration sensor 31 is as shown by A. At this time, the output of an integrator 42 is a signal as shown by B, and this signal is inputted to a first nonlinear element block 43 to take out a positive part as shown by C. The signal is inputted to a second nonlinear element block 44 to invert and output a negative component. Signals of blocks 43 and 44 are inputted to integrators 45a and 45b; and when outputs of integrators exceed a certain value, a high level is set by binarizers 46a and 46b and a reset signal is generated, and therefore, the output of the integrator 45 has a saw tooth wave as shown by D. At this time, pulses are outputted from the binarizer 46a in proportion to the extent of movement in the positive direction. Thus, the mouse is constituted without mechanical parts.

Title: Magnetooptic recording system
IPC: G11B11/105
Filed: 1992-03-31
Abstract: PURPOSE:To greatly reduce jitters of a reproduced signal by irradiating a recording film with light beam pulses in synchronism with a channel clock and providing specific-time delay behind the rise of a magnetic field. CONSTITUTION:A magnetic head 4 produces a magnetic field which is modulated corresponding to recording data and applies it to the part irradiated with the light beam. The peak of the magnetic field of the magnetic head 4 is delayed by a 0.2-0.5 channel bit time behind the rise of the light beam. Consequently, even if the temperature of the recording film or the intensity of the recording magnetic field varies owing to the power control error of the light beam in recording, servocontrol errors of focusing and tracking, etc., the time when magnetism inversion is caused does not vary much, so the jitters are reducible.

IPC: G01J3/36
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To set an optimal integration time of a spectral irradiance meter automatically in a short time regardless of the skill of a worker. SOLUTION: A measuring light is polarized by a diffraction grating for each wavelength before being entered into a light receiving sensor 6. Output from each light receiving element of the light receiving sensor 6 is inputted through an amplifier 7 and an A/D converter 8 to an operating unit 10. The operating unit 10 comprises a section 20 for setting the integration time of the light receiving sensor 6, and a section 30 for converting the signal delivered from each light receiving element into an irradiance for each wavelength. The integration time setting section 20 sets an optimal integration time causing no saturation of output from the light receiving element and the light receiving sensor 6 measures the optical energy of the measuring light during the integration time thus set.  Output from the light receiving sensor 6 is converted at the converting section 30 of the operating unit 10 into a spectral irradiance distribution which is then presented on a display 11.

Title: Data communication adaptor
Inventor: IGAWA KEIICHI
IPC: H04L29/10
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To allow a portable telephone set and a data terminal to directly communicate a control signal with each other and to control the power supply of the portable telephone set from the data terminal. SOLUTION: A data terminal controls a power supply of a data terminal by controlling a level of control signals 1, 2 of an operation section of a portable terminal through the setting of an AT command. Through the setting of an AT command, a signal given to an outgoing serial signal input terminal 3 is outputted to a data input output terminal 7, the signal given to the data input output terminal 7 is outputted to an incoming serial signal output terminal 4 to allow the data terminal to display and edit reception level information or the like from the portable telephone set. Through the setting of an AT command, a transmission rate of an incoming serial signal and an outgoing serial signal is changed to reduce a communication time between the portable telephone set and the data terminal is reduced. Since a control signal by which the portable telephone set transits to the conventional command mode is not outputted to the incoming serial signal output terminal, malfunction of the portable telephone set due to reception of an undefined signal can be prevented.
