Title: Molding of thermosetting resin
Inventor: SENBA KATSUAKI
IPC: B29C35/02
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent the pull or the deformation from occurring at the time of curing by providing a heating means and a temperature sensor which are used for setting the internal temperature distribution of a molding the in such a manner that both heating means and temperature sensor are scattered, and also providing a means for detecting the degree of curing which uses an ultrasonic wave in order to set the degree of hardness of a resin liquid in such a way that the means is scattered. SOLUTION: If molding dies 2a, 2b are locally heated using a heater 8, data detected by a thermoelectric couple 11 is transmitted to a computer 10 through a thermometer 12. On the other hand, if an instruction for the frequency and the rate of propagation of an ultrasonic wave to be oscillated is given to an ultrasonic wave oscillator 24 by the computer 10, an ultrasonic wave transmitted by an ultrasonic oscillator 13 is received upon the oscillation of the ultrasonic wave 14. In addition, data on the detected ultrasonic waveform is transmitted to the computer 10 by an ultrasonic waveform detector 15. The ultrasonic wave is easily propagated between liquid and a solid and is hardly propagated between the solid and gas. Further, the propagation speed of the ultrasonic wave is higher in the solid than in the liquid.  Therefore, the characteristic change is detected by correcting the temperature, and data on the detected ultrasonic wave and the detected temperature transmitted to the computer 10 are analyzed, and the analytical results control a heater power supply control part 9.

Filed: 1985-08-12
Abstract: PURPOSE:To obtain a head feeding device which can control the head position for a long period with high accuracy and high durability and with a simple and inexpensive structure, by providing a magnetic force generating means at the interlocking part between a lead pin and a screw bar to attract them. CONSTITUTION:A head carriage 3 is supported by a guide bar 4 and a lead pin 5 interlocks a screw bar 2 which is extended from the thickness center part of the carriage 3 and set at a rather lower part.

Title: Distance-measuring device
Inventor: TAKASAKI MINORU
IPC: G01J1/42
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain a distance-measuring device by which a signal change can be stored effectively even under a bright environment without a means to increase a chip area or to expand the amplitude of a drive pulse, etc., by a method wherein the difference between a first signal charge and a second signal charge stored in a charge storage means is computed and a noise component due to external light is removed from reflected light from a subject for photography. SOLUTION: An electric charge is injected into a signal-charge storage means 18 by using a signal-charge injection means 17. In this case, when its charge amount is large, the signal charge is injected after the signal charge in a definite amount is removed in advance by a first signal-charge removal means 21 which is installed so as to be adjacent to the signal-charge injection means 17. Thereby, the capacity of the signal-charge storage means 18 can be suppressed to be small. In addition, by a second signal-charge removal means 24 which is installed so as to be adjacent to the signal-charge storage means 18, the electric charge is stored in such a way that an inessential electric charge such as a noise component or the like by external light is removed from the electric charge stored in the signal-charge storage means 18.  As a result, a required electric charge can be stored with good efficiency.
