Title: Voltage detection device
Inventor: SATO SUSUMU
IPC: G05F1/10
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure the root mean square value or mean value of AC voltage, regarding the measurement of the AC voltage. SOLUTION: A frequency detection means 4 outputs a frequency signal proportional to the frequency of detected AC voltage, and an integrating operation means 5 adds the absolute value of the digital signal matrix of AC voltage obtained with an A/D converter 2 by the predetermined times for outputting an integrated result. Furthermore, a phase difference angle operation means 6 finds a phase difference angle signal from the frequency signal of the AC voltage detected with the frequency detection means 4, expressing a digital signal conversion period in the form of the phase of the AC voltage. Also, a normalizing operation means 7 multiplies the integrated result by a voltage correction ratio obtained on the basis of the phase difference angle signal and, then, outputs a normalized voltage detection signal. As a result, an operation error is corrected.

Title: Photoelectric sensor
Inventor: KAMEI TAKASHI
IPC: H01H35/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a light-receiving signal in the object detecting state in advance and automatically set the optimum integration value by providing a discrimination section discriminating the light-receiving signal from a light-receiving section at the prescribed threshold value, an integration value control section controlling the optimum integration value based on the times of continuous shading or light entry, while a detection object passes at the prescribed speed, and an integration section. SOLUTION: A light-receiving element 4 receives the light passing through an object detection region, and its output is fed to an integration value control section 8 and an integration section 9 via a gate circuit 6 and a threshold value discriminating section 7. When the threshold value discriminating output is continued by the number of times set by the integration value, i.e., evaluation times, the integration section 9 outputs the detecting signal corresponding to the output of the number of times. An optimum integration value judging section 14 of the integration value control section 8 judges the optimum integration value based on the frequency of projected light pulses, and an integration value change section 15 sets it on the integration section 9.  The optimum integration value can be set, in response to the object of a photoelectric sensor, and the photoelectric sensor can be used in an optimal state according to the operating environment.

Title: Seismoscope
Inventor: ABE HIROO
IPC: G01H11/08
Filed: 1991-10-31
Abstract: PURPOSE:To prevent the erroneous detection when a seismoscope is installed slantly against the horizon. CONSTITUTION:In a seismoscope arranged with a cylindrical piezoelectric film 3 on the outside of a heavy bob 2, the heavy bob 2 is made of a magnetic substance, and it is attracted to the center position of the piezoelectric film 3 by a magnet 4 provided on the bottom face of a case 1.
