Title: Non-contact diameter measuring instrument
Inventor: INAGAKI SHINTARO
IPC: G01B11/10
Filed: 1985-07-15
Abstract: PURPOSE:To easily execute a measurement and with a high accuracy even in case of a moving object, by projecting an image of a circular object to be measured, moving at a constant speed, to a photodetector, and calculating a diameter, based on the time until a specified peak appears in its output signal. CONSTITUTION:A circular image 4 of a moving circular object to be measured 3 is projected onto a photodetector array 1 by an optical system 2. This photodetector array 1 connects alternately 2n pieces of detectors, inputs its two pieces of output signals to a differential amplifier circuit 5 and obtains a signal having 2n pieces of peaks. In this state, first of all, the time to the first peak of the output signal, and its amplitude are measured by an arithmetic means 7, and from those values, an approximate diameter is calculated. Also, by an arithmetic means 8, a moving speed of the circular image 4 is calculated from the appearance time of a peak of the output signal of the time when the circular projected image 4 has been held completely on the photodetector array 1, and from its moving speed and the peak appearance time, a diameter is calculated.

Title: Stabilized higher harmonic generator
Inventor: MISAWA SHIGEYOSHI
IPC: G02B6/12
Filed: 1992-05-21
Abstract: PURPOSE:To prevent the degradation in the output of a second higher harmonic in spite of a fluctuation in an incident basic wavelength and a change in ambient temp. CONSTITUTION:Periodic polarity inversion layers 2 are formed on a substrate 1 having a nonlinear optical effect and an optical waveguide 3 is formed in this substrate 1. A resistance heating element 5 is loaded via a buffer layer 4 consisting of an insulator on the optical waveguide 3. The basic wave is excited by the optical waveguide 3 when the exit light from a light source is condensed to one end of the optical waveguide 3. The second higher harmonic IC is then phase matched affinely with the basic wave by the effect of the polarization inversion layers 2 and the substrate 1 and is emitted from the other end of the optical waveguide 3. Since the temp. of the optical waveguide 3 is changed by the resistance heating element 5, the stable generation of the higher harmonic is possible.

Title: Non-contact point-type ignition apparatus
Inventor: ISHIKAWA HIROYUKI
IPC: F02P3/05
Filed: 1978-12-21
Abstract: PURPOSE:To prevent an ignition timing lag resulting from an increase in rotational frequency for pickup coil SG whose output voltage slowly builds up, by varying the level by which an output transistor is turned on and off due to the output of pickup coil SG. CONSTITUTION:The potential of SG's terminal 1 is conducted to a base of transistor Q7 on the Schmit circuit (including Q7, Q6) through the intermediary of resistance R10, and further controls control transistor Q3 via Q6, Q5 and Q4. That is, if the output voltage of SG was increased in a normal direction and a potential of the terminal 1 reached a sufficient level for turning on Q7, Q3 is cut off, resulting in the turn-on of output transistors Q2, Q1. In the meantime, if the output of SG is reduced from a positive peak value, Q7 is cut off and Q3 is driven until it reaches a saturation state, while Q2 and Q1 are rapidly cut off. At this moment, high voltage is generated on the primary winding of ignition coil lg, causing a spark on ignition plug PLG through the secondary winding.

Filed: 1984-07-27
Abstract: PURPOSE:To solve a thermal stress interference for active layer of laser element or light emitting diode by forming a sintered body mainly composed of alumininum nitride as the material for pedestal of semiconductor element.

Therefore, the function of active layer can be stably operated for a long period of time.
