Patent JP-S60128316-A (JP)
Title: Infrared sensor
Inventor: TAKEUCHI KOUSUKE
IPC: G01J1/04
Filed: 1983-12-15
Abstract: PURPOSE:To improve S/N and reliability by setting the surface electrode to a constant potential, and also applying a driving signal which becomes an AC with respect to the constant potential, to the center electrode. CONSTITUTION:Vibrating bodies 48, 49 are vibrated basing on a voltage applied to the third and the fourth terminals 22c, 22d. That is to say, a DC constant- voltage of about +5 volts is applied to the fourth terminal 22d so that each surface electrode 53a, 53b and 54a, 54b becomes a constant potential. On the other hand, voltages of about +35 and -25 volts are applied alternately and periodically to the third terminal 22c in order to apply a driving signal which becomes an AC with respect to the constant potential, to center electrodes 50a, 50b. As a result, a state that the center electrodes 50a, 50b become 30 volts higher than the surface electrode, and a state that the former becomes lower by 30 volts are repeated alternately. As a result, an infrared-ray detecting body varies periodically an incident infrared-ray quantity, and outputs a signal corresponding to a temperature difference of an object to be detected and opposed bodies 56, 57.

Title: Cord housing device for electric cleaner or the like
Inventor: HASHIZUME KIYOSHI
IPC: A47L9/26
Filed: 1988-09-22
Abstract: PURPOSE:To reduce the scratch or damage of a cord and a cord exit hold and to prevent the winding defect of the cord by arranging the cord exit hole in a position to be an outer circumference rather than the minimum drum diameter of a cord reel and to be an inner circumference rather than the maximum drum diameter of the cord reel. CONSTITUTION:When a cord 8 is drawn, the cord 8 lightly gets contact with the lower edge of a cord exit hole 9 since the cord exit hole 9 is positioned inside rather than a maximum drum diameter D2. When the cord 8 is further drawn, the cord 8 can be drawn without being in contact with the outer circumference of the cord exit hole 9. In the final step of the cord drawing, the cord 8 lightly brought into contact with the upper edge of the cord exit hole 9, namely, with a cord stopper 1b. Accordingly, in an almost condition at time of drawing, the cord 8 can be drawn without being in contact with the surrounding wall of the cord exit hole 9. When the cord 8 is wound, the cord 8 is wound with being in contact with the lower edge of the cord exit hole 9 since the cord 8 rapidly rises up from a floor surface and goes into a cord reel room. Accordingly, resistance is operated to the winding of the cord 8 and the winding speed of the cord 8 is relaxed.

Title: Scanning acoustic microscope
Inventor: HISADA NAOKO
IPC: G01N29/22
Filed: 1990-09-07
Abstract: PURPOSE:To quickly and positively adjust the microscope thereby to save labor for inspection by storing the time from when an ultrasonic wave is emitted to when the ultrasonic wave is received when a peak of an echo is detected, and automatically controlling the posture of the microscope to a sample so as to maintain the same condition during scanning. CONSTITUTION:A pulse wave signal from a pulse transmitting part 1 is electrically acoustically converted to an ultrasonic pulse by a transducer 2. The ultrasonic pulse is incident upon a sample 5 through an acoustic lens 3, and the reflective wave is, through the lens 3, converted to a receiving signal by the transducer 2 and output from a preamplifier 7, subjected to gate action by a gate part 8 with a calculated timing, so that only the reflecting wave in the vicinity of an expected focal point is extracted. The extracted signal is input to an attenuator 9 to be attenuated by a predetermined amount set by a computer 14. The intensity of the output signal from the attenuator 9 is compared with a threshold value at a comparator 11. If the signal passing the attenuator 9 is larger than the threshold value, the output signal is turned ON. The computer 14 adjusts the attenuating amount of the attenuator 9 so as to turn the signal ON from OFF at all times.

Title: Control system of information processor
Inventor: TAKESHITA MASARU
IPC: G06F13/00
Filed: 1984-11-12
Abstract: PURPOSE:To attain the rise of a system without waiting the loading of program data by loading data stored in a ROM memory device on a main memory device at rise and correcting it based on correction data stored in an EEPROM memory device. CONSTITUTION:Since program data is transferred to the main memory device from the ROM memory device at the time of the rise of a system, its transfer and load is remarkably quick. When storage contents in the ROM memory device 2 should be corrected, only the correction content is stored in the EEPROM device. This correction has flexibility because the contents are corrected at processing. Since only an address to be corrected is stored in the EEPROM device, its transfer requires no long time. Thus the system rise can be executed quickly and securely, and the EEPROM memory device can easily correct backup program data.
