IPC: H04B10/077
Filed: 1986-12-19
Abstract: PURPOSE:To remarkably reduce power consumption for conversion to an optical signal, by arranging a timer in a sensor circuit, setting all of the sensors at detecting states at every prescribed time interval, and transmitting the optical signal after forming the optical signal representing the detecting state in a short optical pulse via an optical fiber. CONSTITUTION:The output (a) of the timer 7 is outputted at every prescribed time interval T1 for a short time, and the detecting state is generated by bringing a part of two conductors of a sensor part into contact with each other by the output. A pulse generator 2 is oscillated by the output, and a light emitting element 3 generates the optical signal (b) of optical pulse string with a pulse cycle of T2. Thus, since the optical signal is sent only in diagnosing by the sensor or at the time of generating abnormality, and simultaneously, the sending of the optical signal is performed at every prescribed time interval T1 as the optical pulse string with time width of T2 by the pulse generators 2 and 8, it is possible to remarkably reduce power required for light emission.

Title: Ultraviolet detector
Inventor: SUYAMA MOTOHIRO
IPC: G01J1/02
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized ultraviolet detector which can detect the irradiating quantity of ultraviolet rays in a specific wavelength region in the form of an integrated value and can detect ultraviolet rays without requiring any power supply. SOLUTION: An ultraviolet-ray detector 1 is provided with an ultrasonic detecting device 3 and a container 4 and the device 3 is fixed on the container 4. The electrodes of the device 3 are bonded to lead-out pins 6, 7, etc., provided on the container 4 through wires 9 and used for measurement from the outside of the detector 1. The device 3 is provided with two ultraviolet detecting elements. Each element is composed of an EPROM type semiconductor element which detects irradiated ultraviolet rays in the form of an integrated quantity. Since an ultraviolet filter which selectively passes a specific wavelength is formed on one ultraviolet detecting element, the difference between the integrated quantities of charges of the two elements found by measuring the drain currents of the elements indicates the difference between the integrated value of ultraviolet doses caused by the filter.  When an appropriate filter is used, the ultraviolet-ray detector can be applied to a pyrheliometer.

Title: Multi-channel automatic ultrasonic testing method for rolled metallic plate and its device
Inventor: TAKADA HAJIME
IPC: G01N29/38
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent misrecognition of defect and remaining of untested area by obtaining the upper limit of time when no defect can be found by a plurality of ultrasonic probes at the same time and setting it at the closing timing of defect defecting gate. SOLUTION: When a width of a gate signal 22 is Wo at the time when gate circuits 131 to 135 close defect detection gates at a timing t0 in accordance with nominal plate thickness, a gate signal where the gate width from Wo -δ to Wo +ε (δ, ε: optional value) is changed at a specified pitch in time is generated successively by a gate control circuit 14, and the output of defect detection gate is monitored by a micro computer 15. The width W1 of upper limit gate signal in which respective separate ultrasonic probes 101 to 105 cannot detect any defect simultaneously is obtained, and the width W1 is set in a gate control circuit 14. Thus, while the width of the gate signal 22 is changed, the level of signals 231 to 235 showing the presence or absence of internal defect is monitored, further the upper limit W1 of width of a gate signal where the output of five gate circuits 131 to 135 is still at a low level. Therefore, when the width of the gate signal 22 is fixed at W1 , the defect detection gate can be closed immediately before rising of bottom reflection wave.
