IPC: G01J1/02
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To obtain a system whose reliability is high and which can detect a signal at high degree in terms of quality by a method wherein a self-testing device for heat generation is provided and a sensor element can be heated. SOLUTION: A slender groove 54 is formed on a substrate 15, it is covered with a heat insulating layer 51, and sensor elements 10 are installed on the heat insulating layer 51 in such a way that a part or more of them is situated at the upper part of the groove 54. The high-temperature side of the sensor elements 10 is situated under an absorption layer 55 at the upper part of the groove 54, and the low-temperature side is situated at the upper part of both partitions 32. In a self-testing operation, self-testing device 53 (resistance elements) heat the sensor elements 10 so as to check whether the respective sensor elements 10 output a signal or not as desired. In this manner, the function of every or all of the elements 10 can be checked.  Since the participating mass of the elements 10 is small, the self-testing operation can be performed at a comparatively short time constant, and it is useful in an application field such as, e.g. an automobile. Thereby, it is possible to obtain a system whose reliability is high and which can detect a signal at high degree in terms of quality.

Inventor: HAYASHI HIDEKI
IPC: H03K17/04
Filed: 1984-10-31
Abstract: PURPOSE:To obtain a forward recovery characteristic while an effective forward voltage at a high frequency operation is reduced by decreasing an anode-cathode voltage just after an anode current from a main circuit starts flowing. CONSTITUTION:The anode-cathode voltage in replacing a diode into a thyristor 2' has a slight value because a minute anode current is fed from a DC power supply 5 through a control switching element 6, a resistor 8 and a diode 9 from a point of time T1 when a trigger gate signal is given until a point of time T2 when the anode current starts flowing from the main circuit. Although the anode current starts flowing from the main circuit at the point of time T2, the anode-cathode voltage is a far smaller value than the case where no minute anode current flows from the point of time T1 until the point of time T2. Further, the anode current is this state is shown in figure E.

Title: System for synchronous production instruction to assembly line
Inventor: KONUMA YOHEI
IPC: B23Q41/08
Filed: 1987-09-16
Abstract: PURPOSE:To enable the practical application of timely production instructions by judging the advance and delay of production in an assembly line on the basis of the time of actuating the line and the predetermined production pitches, and outputting the advance and delay of the production to a part of production instruction information. CONSTITUTION:A completed article in a preceding stage is accumulated in a buffer and shifted to the input stage 3 of an assembly main line 1. Upon the shift of the article, a tact signal 9 is inputted, thereby recognizing that the article is shifted from the line 1 by one stage. Then, instruction information to a production instruction output device 8 is determined by the contents of the definition table of a work instruction output point and the buffer table of time for work instructions. And timing for outputting to the output device 8 is made by inputting the signal 9 of a subline 2. And as a delay in production in the line 2 causes an asynchronous condition with the line 1, a delayed shift number and delayed time are added to work instruction information for output. And an action for recovering the delay is taken at a work site and when work is in an advanced stage, work instructions are outputted by priority within an allowable advanced instruction number from the maximum number of works half done in a buffer for the line 2, thereby preventing excessive production.

Title: Signal processor for multiplex sound broadcast
Inventor: KAWABATA TERUO
IPC: H04H1/00
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To execute low-pass signal processing corresponding to a broadcast mode. SOLUTION: A television receiver 1 is capable of receiving mutiplex sound broadcast and executes the processing of a low-pass boost (low-pass emphasis) corresponding to the structure and constitution of a cabinet main body and speakers 13L and 13R. In the case of setting an automatic sound quality adjusting mode by operating a key operation part 19 or a transmitter 21, when an audio signal SA is a stereo broadcast, filter circuits 11L and 11R do not respectively execute low-pass attenuation processing to the audio signal SA so that a low band is emphasized in the sound outputs of the speakers 13L and 13R by low-pass boost processing.  When an audio signal SA is not the stereo broadcast, the filter circuits 11L and 11R respectively execute low-pass attenuation processing to the audio signal SA to cancell low-pass boost processing so that the low band is emphasized in the sound outputs of the speakers 13L and 13R as the result. Consequently, low-pass signal processing is properly executed corresponding to the broadcast mode.
