Title: Continuous press molding method for lengthy product
Inventor: YAMAGUCHI KATSUMI
IPC: B29C43/22
Filed: 1987-06-30
Abstract: PURPOSE:To manufacture a continuous molded product of almost uniform thickness in its whole length by press molding a short length synthetic resin sheet while preventing the molten resin from flowing out at a rear end pinch-off section of a press mold, and simultaneously welding the front end of the short length synthetic resin sheet with the rear section of said molded product to connect together integrally. CONSTITUTION:When press molding is completed, a top force main body 11a and a press molding die 11b are lifted up, and a solidified molded product is released in a manner that its rear end is left in a press mold 1. Then, the rear end of said molded product X is press fixed with the press molding die 11b which is lowered after release. In said state, a following heated short length synthetic resin sheet X2 is set in the press mold 1, and the top force main body 11a is lowered to carry out press molding again. By said arrangement, the front end of the short length synthetic resin sheet X2 is welded with the rear end of the foregoing molded product X in a state of butting to be connected together integrally, and is molded in the thickness similar to that of the foregoing molded product A, because the molten resin is prevented from flowing out at a rear end pinch-off section 13 of the press mold 1.

IPC: G01N29/24
Filed: 1994-06-22
Abstract: PURPOSE:To provide an acoustic lens that is near to an ideal because it has less damping by forming the acoustic lens for a probe of a ultrasonic diagnostic device with the mixture of silicone rubber and butadiene rubber, so that the sound velocity thereof can be sufficiently lessened than that of the human body. CONSTITUTION:An acoustic lens that is provided to the portion where it is brought into contact with the human body for converging ultrasonic beams in a probe of a medical ultrasonic diagnostic device is formed with the mixture of silicone rubber and butadiene rubber, which is manufactured by mixing the silicone rubber and butadiene rubber so as to be vulcanized. In this case, the mixing ratio of silicone rubber to butadiene rubber is set to be 1:1. In the case of vulcanization, if necessary, zinc oxide is added in the mixture of silicone rubber and butadiene rubber as a vulcanization accelerator. Thus, the acoustic impedance thereof is approximated to that of the human body, and also the sound velocity therein is lessened than that of the human body, so that an ideal acoustic lens having less damping can be obtained.

Title: Production of optical waveguide
Inventor: HORI AKIHIRO
IPC: G02B6/13
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To produce an optical waveguide having high dimensional accuracy and good perpendicularity in the cross section without decreasing the etching rate by using CHF3 and C2 F6 as an etching gas. SOLUTION: When an oxide film is subjected to dry etching, a substrate 18 is disposed on a lower electrode 3 between the upper and lower electrodes parallel to each other. An annular member 19 comprising almost the same material as the substrate 18 to be etched is arranged to surround the substrate 18. The upper face of the substrate 18 is pressed by a clamp 20 comprising almost the same material as the substrate 18, while the back surface of the substrate is held in an The gas atmosphere. The lower electrode 3 is chilled by a coolant, and CHF3 and C2 H6 are used as an etching gas. Namely, by adding C2 F6 etching gas which easily causes side etching, the side faces of the core are etched to prevent formation of a trapezoid cross section.  Thus, the substrate is etched with high dimensional accuracy of the core and good perpendicularity in the cross section without decreasing the etching rate.

Filed: 1988-06-30
Abstract: PURPOSE:To prevent to deposit a component to be measured at a nozzle and to block the nozzle even though the component to be measured in a gas phase sample is highly dense by feeding the sample to a sample collecting valve to fill the inside of a measuring pipe of a constant inside volume, and then, leading the sample collecting valve to the inner chamber of a plasma torch with a switching carrier gas. CONSTITUTION:After the inside of a measuring pipe of a constant inner volume is filled by feeding a sample to a sample collecting valve 17, the sample collecting valve 17 is led to the inside chamber 3 of a plasma torch with a switching carrier gas. In this case, the sample collecting valve 17 may be a four-side switching valve including a back pressure regulator formed as a three- side switching valve, or two four-way switching valves holding a single measuring pipe. By such a constitution, a component to be measured is never deposited at a nozzle, or it never blocks the nozzle, even though the component to be measured is highly dense.

Filed: 1990-06-21
Abstract: PURPOSE:To achieve an efficient acceleration test by inputting a control signal and generating a signal which is equivalent to a signal which is input externally in normal operation using a test circuit. CONSTITUTION:In acceleration test, control signal is input to a terminal Ta for activating a timing control part 16A. Also, a clock is input to the terminal Ta. Then, a binary counter 18A counts it.

Abstract: PROBLEM TO BE SOLVED: To shorten the working time of a code groove, and to improve the accuracy of working by inserting a keyhole inserting section into a keyhole, engaging and releasing a tumbler in a cylinder lock by the code groove and connecting the code groove to a key plate conducting locking and release. SOLUTION: A point, where the lower end face of a milling cutter for the key plate K1 is lowered up to the depth of code grooves 11, 12, is used as a starting point in the milling cutter having approximately the same diameter as the width of the two strips of the code grooves 11, 12. A table is moved in the direction that the cutting of the pushing moving surface of the code groove 11 is directed towards upward shaving, and the code groove 11 is worked from the front end of the keyhole inserting section 10. A connecting groove 13 is worked from the rear end section of the code groove 11 and transferred to the rear end section of the code groove 12, and moved to the front of the keyhole inserting section 10 after the machining of the code groove 12 and returned to a starting point. Pushing moving surfaces are shaven upwards even in the working of the code groove 12, and both pushing moving surfaces are machined with high accuracy by one-time cutting works of the milling cutter. Accordingly, the working time of the key plate K1 is minimized, and working size and the accuracy of a finished surface can be ensured.

Filed: 1983-09-06
Abstract: PURPOSE:To contrive the simplification of the mounting of a pressure sensor chip by a method wherein a pedestal and said chip are sealed hermetically by application of silicon rubber on the pedestal formed by hardening silicon rubber. CONSTITUTION:The pedestal 8 formed by hardening of silicon rubber is hermetically fixed to a hermetic terminal 4 with silicon rubber, organic adhesive, etc. After the silicon rubber 9 is uniformly applied on the pedestal 8, the pressure sensor chip 1 is placed on the rubber 9.

Title: Optical heterodyne detection communicating method
Inventor: YAMAZAKI SHUNTARO
IPC: H04B10/556
Filed: 1987-07-02
Abstract: PURPOSE:To set a modulation index at a comparatively small value by providing a light receiving part with a differential detection circuit, the delay time of which is n-bits, and inputting a first intermediate frequency signal to it, and demodulating a signal by a second intermediate frequency signal, appearing in the output of it. CONSTITUTION:The first intermediate frequency signal is obtained by transmitting an FSK modulated signal light from a light transmitting part, and receiving the FSK modulated signal light by the light receiving part, and the first intermediate frequency signal is inputted to the differential detection circuits 5, 6, the delay time of which is n-bits (n is one or larger integer), and a demodulated signal is obtained by demodulating the second intermediate frequency signal, appearing in the output of the differential detection circuits 5, 6. Accordingly, because the considerable part of the influence of the FM noise of a light source is absorbed by the differential detection circuits 5, 6, this influence comes difficult to appear in the demodulation of the signal. Thus, the dependency of a required modulation index upon the spectrum width of the light source and a bit rate can be extremely reduced, and in addition, the modulation index can be set at a comparatively small value.
