Filed: 1991-08-20
Abstract: PURPOSE:To prevent rotational change of an internal combustion engine even at the time of generating an intermittent electric load by providing a correction means to advance an ignition time in accordance with the amount of change in the case when a rotational load increases and to delay the ignition time in the case when the rotational load decreases at the time to detect a transient change of the rotational load of a generator by a transient load detection means. CONSTITUTION:A microcomputer 3 detects the status of a rotational load of a generator 1 by a field current and judges whether to correct an ignition time of an ignitor 7 or not in accordance with signals from an idle switch 4, a rotation sensor 5 and a shift position detection switch 6. Thereafter, the microcomputer 3 controls motion of the ignitor 7 by computing the correction amount in correspondent with the status of the rotational load of the generator 1. As the ignition time, hereby, is a factor to directly control torque of an internal combustion engine, rotational change of the internal combustion engine is prevented by correcting the ignition time.

Title: Semiconductor disk device
Inventor: MURANO SHOICHI
IPC: G06F12/16
Filed: 1985-09-20
Abstract: PURPOSE:To prevent the generation of a 2-bit error by adding a hard error processing means to instruct the processing procedure of a control part when this control part decides that the generated 1-bit error is caused by a hardware. CONSTITUTION:When it is decided that the 1-bit error detected during the transfer of data between a semiconductor disk controller and a semiconductor memory is caused by the hardware, a control part transfers the data equal to the amount of the corresponding track that is stored in a data register and has an error generated to an HD via an MDC based on an instruction given from a hard error processing means. Then the corresponding track where a 1-bit error is produced to a semiconductor disk controller is transferred to the HD. The information obtained under such conditions such as the track number and the processing contents obtained in the access mode of said track number, etc. is reported. Hereafter the accesses if given to said track are processed against the HD. Thus it is possible to prevent the generation of a 2-bit error.

Title: Voice guide system of transmission type of radio wave and infrared ray or the like
Inventor: NUMAZAKI SHINICHI
IPC: G09F25/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To narrow the range of a literal information supply to a receiver against visually handicapped persons or the like, and to obtain automatically a guide information in a facility or the like, by establishing a sensor-sensitive area within a small range, and by transmitting a recorded voice guide by operating a transmitter in case that a person enters within a prescribed distance. SOLUTION: When a visually handicapped person walks, carrying a receiver 22, in a facility, an infrared-ray sensor 24 built in a transmitter 21 perceives that he enters an area within a prescribed distance, then a base sound (sound of a 'bell-ring' insect) is produced and a transmission of a guide information is started from an electronic-sound speaker 25. He can acknowledge the guide information by the sound of a 'bell-ring' insect, and also he can hear the guide information as a voice by the receiver 22. When the visually handicapped person goes out of the sensitive area of the infrared-ray sensor 24, the transmission and the operation of the electronic sound are stopped.  Besides, even when a person except a visually handicapped person enters the sensitive area of the infrared-ray sensor 24 of the transmitter 22, a transmission of the guide information and a production of the base sound are operated, but he can hear only the sound of the 'bell-ring' insect, so the sound is not offensive to his ears.

Abstract: PURPOSE:To perform stable and highly efficient wire-cut machining operation, by providing a control circuit with a brake variable control unit for supplying a control signal based on a vibration sensing signal to control tension in accordance with vibration of a wire electrode. CONSTITUTION:A sensor 8 radiates a light beam from an LED 81 to a confronting wire electrode 1 and a reflected light beam is sensed by a photo transistor 82 so that a sensing output senses a signal changing depending on a vibrating condition of the electrode 1. Therefore, when intensive discharge is produced across the electrode 1 in discharge machining operation and a workpiece 7, a number of vibration of the wire is increased to increase a frequency of a signal conversion circuit 9 so that a control signal is applied from a discriminating circuit 10 to a control unit 11 to decrease a braking force. Further, when the electrode 1 is out of a confronting machining surface of the workpiece 7 to be bent, a frequency signal is reduced by a decreased number of vibration of the electrode 1 so that a command is applied from the discriminating circuit 10 to the control unit for increasing a braking force. When a brake 3 is weakened in a case that intensive discharge is produced, tension of the electrode 1 is loosened, whereby breakage of loosened, whereby breakage of the electrode is prevented. Thus, a machining speed and accuracy can be improved.

Title: Acceptance judgment method for headlight
Inventor: MURATA NAGATOSHI
IPC: G01M11/06
Filed: 1994-09-01
Abstract: PURPOSE: To provide an acceptance judgment method in which the acceptance of a headlight can be judged simply in an optical axis adjusting process by a method wherein the acceptance of the headlight is judged on the basis of the shape of an imaged virtual light source image. CONSTITUTION: An imaging operation is performed by using the principle of a pinhole camera or the like. An irradiation pattern B having a leftward-rising light and shade boundary line as well as a left virtual light source image L and a right virtual light source image R are imaged respectively on screens 2, 7 in a case in which, e.g. a headlight HL is of a cutoff type for a right side passage. On the basis of shapes of the light source images L, R, the quality of the headlight HL is judged. That is to say, when a filament is dislocated or a reflector is distorted, the area of the light source image L becomes smaller than that of the light source image R, or the shape is distorted, and a regular trapezoidal shape is not obtained. In addition, when the filament is abnormal and its quantity of light is dropped, the shape of the light source image L is distorted. Consequently, when the ratio of the area of the light source image L to that of the light source image R is at a prescribed value or lower, the headlight HL is judged to be defective when the light source image L is not the regular trapezoidal shape.
