Title: Crack detector
Inventor: KASHIUCHI YOSHINOBU
IPC: G01N21/88
Filed: 1979-09-28
Abstract: PURPOSE:To ensure an assured detection of the crack, by irradiating the light to the throwaway chip with an angle of the best S/N at all times. CONSTITUTION:The throwaway chip 1 is shifted while keeping the angle formed by the projected light 2 and the chip side, and thus the entire end parts of the chip 1 are image-formed to the photoelectric transducer 4. And if some crack is caused at the end parts of the chip 1, the output of the transducer 4 has some change. The angle between the chip 1 and the projected light is set preferably to about 50-80 deg.; and the transducer 4 is provided preferably with an angle orthogonal to the side of the chip 1 since the transducer 4 receives the diffused reflection of the reflected  light.

Title: Transmission and reception switching circuit of ultrasonic vibrator
Inventor: KOTANINO KIYOSHI
IPC: G01S7/52
Filed: 1981-08-14
Abstract: PURPOSE:To ensure the transmission of a large output for a wave transmitter/ receiver for long-distance sonar, by inserting a reed relay contact between the coils of a matching transformer which is stored in a water tight holder of the transmitter/receiver and then turning on the transmission only. CONSTITUTION:The transmission voltage is applied to terminals A and B of a wave transmitter/receiver 100, and a part of this transmission signal undergoes the half-wave rectification through a diode 114 and flows to a capacitor 116 and a Zener diode 115. Thus a reed switch 113 is turned on. As a result, the transmission voltage is boosted by a matching transformer 12 to drive an vibrator 11. While in the reception mode, the switch 113 is kept off since the reception voltage is faint. Thus the reception voltage is supplied between the terminals A and B with no step-down. In such way, the transmission of a large output is possible in a state under which the loss of the transmisson voltage can be ignored.

Abstract: PURPOSE:To prevent abrasion owing to movement of filter media by providing a vessel packed with mineral filter media which dissolve and extract mineral contents in carbonated water and providing a porous body which moves the filter media in the pressurizing direction in the fore stage of the filter media which are salts contg. minerals. CONSTITUTION:The carbonated water from an automatic supplying device 2 for a gaseous CO2 at a constant rate flows into a vessel 4 packed with mineral filter media through its inlet 6 and passes through a porous body 11, by which its flow is rectified. The carbonated water is dissolved and extracted with minerals by contact with filter media 9 which are acid salts contg. minerals. Said water is discharged as mineral water through a discharge port 7. Since the body 11 slided along the inside wall of a cartridge 8 is provided in the fore stage of the acid salts contg. minerals are mentioned above, the carbonated water flow passes through said body 11 while forcing the body upward thereby pressurizing the medial 9 and eiliminating cavities. Thus the movement of the media 9 by the carbonated water flow is entirely suppressed.

Abstract: PURPOSE:To contrive to enhance the speed and to enhance the withstand voltage of a drain earthed laterally structural insulated gate field effect transistor by a method wherein a high concentration impurity buried layer is provided in the neighborhood directly under the source thereof as not to reduce the withstand voltage between the source and the drain. CONSTITUTION:An N type buried layer 2A is formed in a high resistivity P type substrate 1A, and after N type epitaxial layers 3A-3C are formed, P type diffusion layers 4A, 4B to be used for element isolation and as the drain of a laterally structural MOSFET are formed. After then, formation of a gate oxide film 101, formation of a poly-Si gate 7A, ion implantation for formation of a P type impurity diffusion layer 5A to enhance the withstand voltage, formation of a P type diffusion layer 8A, formation of an N type diffusion layer 9A to short-circuit between the epitaxial layer and the source, formation of contacts, and formation of Al wirings are performed according to the manufacturing method of the usual high withstand voltage laterally structural MOSFET. Accordingly, because the high concentration impurity buried layer 2A is existing in the neighborhood directly under the source diffusion layer 8A, a punch through is hard to be generated between the source and the drain (the substrate), and the effect of a vertically parasitic PNP transistor can be reduced, too.

Abstract: PROBLEM TO BE SOLVED: To feed a sheet type body such as a paper sheet with minimal skew by constructing the surface of a roller of a circular arc curved face so that the roller diameter of the center part is reduced as compared with those of the both end parts. SOLUTION: A diameter of the width directional center of a grinding wheel 1 of a centerless grinding device is slightly increased in comparison with those of width directional both ends, and the outer circumference face of the grinding wheel 1 is swelled in the center like the outer circumferential face of a drum. When a metallic roller is ground by means of the grinding wheel 1, a drum shaped roller 3 with a thin center part and thick both ends is formed. The outer circumference face of the roller 3 is formed into a circular arc face with a radius R of curvature.  When a sheet type body such as a paper sheet is conveyed by means of the drum-shaped roller 3, a face pressure distribution with the sheet type body is formed into a laterally symmetric distribution in which a pressure is increased in the width directional both ends and reduced in the center, so that the sheet type body can be linearly fed with little skew in spite of fluctuation in the surface machining precision of the roller 3 or in the width directional thickness.
