Title: Ultrasonic probe
Inventor: TORIGATA KOJI
IPC: G01N29/28
Filed: 1985-04-12
Abstract: PURPOSE:To set an ultrasonic probe in the best state at any time by allowing at least either of a contactor and a vibrator to move freely so that the area of contacting between the contactor and vibrator is variable. CONSTITUTION:The contactor 1 made of a flexible material such as silicone rubber has a conic projection 1A and is fitted in the hole 3 of a case 2. The vibrator 4 is put in the hole 6 of a fitting member 5 together with a damper 7 and its surface is covered with a front surface plate 8. When an ultrasonic analysis of the body is taken by using the contactor 1, the depth up to the echo generation point of an ultrasonic wave is measured previously and the member 5 is so rotated as to obtain the limit distance of a short-distance sound field, thereby increasing the area of the contactor 1 which is pressed against the vibrator 4. Then, the reverse surface of the contactor 1 is brought into contact with the skin surface of the body through a contact medium such as grease and an ultrasonic wave is transmitted into the body, so that the contactor 1 receives an echo from a position to be inspected with good sensitivity.

Title: Photoresist exposure method and its device
Inventor: WATANUKI MINORU
IPC: G03F7/20
Filed: 1989-03-29
Abstract: PURPOSE:To eliminate unbalanced exposure and to achieve precision circuit image forming by exposing the inside wall of a through hole in a position close to a working body, while rocking a light source and exposing a substrate surface in a position apart from the working body. CONSTITUTION:To resist-exposure the inside wall of the through hole inside of the working body 2, a lamp housing 17 is shifted from a central part to a lateral part, and a mercury lamp 10 is shifted to one side and lowered and approached to the working body 2. The mercury lamp 10 irradiates the working body 2 with light via a negative film 4 used only for the through hole while rocking along the surface of the working body 2. The inside wall of the through hole can thus be uniformly exposed. The resist exposure of the surface of the working body 2 is performed in such a manner that the mercury lamp 10 is shifted to the central part and pulled upward to place a distance apart from the working body 2 thereto, and the precision circuit image forming film 4 is adhered, to the working body 2 thereby irradiating the working body 2 with parallel light beams. Consequently, an precision circuit image can be formed in the surface on the working body 2.

Title: Hot stove
Inventor: TAKAHASHI MASAOKI
IPC: C21B9/14
Filed: 1979-06-20
Abstract: PURPOSE: To make the temperature of exhaust gas constant and improve heat exchange efficiency by conneting a heat exchanger to the exhaust gas system of a regenerator by way of a soaking device.  
     CONSTITUTION: Combustion gas and combustion air led to a burner 6 via a fuel feed pipe 7 are burned in a combustion chamber 5. After the exhaust gas is supplied to the accumulated heat in two regenerators 2 by way of an inlet side exhaust gas pipe 4, it is led into a soaking device 11 by way of an outlet side exhaust gas pipe 9, that is, exhaust gas system 10. The exhaust gas entered the soaking device 11 is deprived of the heat by the heat accumulation action and is decreased of its temperature when the temperature is high and is given heat by heat radiation action  when its temperature is low and is ascended of its temperature, thus it is maintained always at constant temperature, and it is sent out from the outlet 11b of the soaking device 11 to the heat exchanger 12 through the exhaust gas system 10. The exhaust gas of constant temperature led into the heat exchanger 12 contributes to the preheating of the combustion gas and combustion air in the fuel feed pipe 7 here, after which it is relased into the atmosphere through a chimney 13. One of the regnerators 2 is used for regeneration and the other for heat radiation, whereby the single operation is achieved.

Title: Floating-up preventing method for pump water-wheel rotary part
Inventor: TAKAHASHI JIROU
IPC: F03B15/00
Filed: 1978-06-29
Abstract: PURPOSE: To prevent the floating-up of the pump water-wheel rotary part by feeding fluid under pressure bewteen the upper cover and the runner upper part of a pump water-wheel, when the connection between the shaft of the pump water-wheel and the shaft of a dynamotor is disconnected in a pumping-up power station.  
     CONSTITUTION: When a water-feeding pump 4 is driven, a water-feeding valve 13 is opened, and the pressurized water having a water pressure which exceeds the water pressure corresponding to the pressure water head is applied to the upper surface of a pump water-wheel runner 4 through a water-feeding seat 12 arranged on an upper cover 10. Owing to the sealing effect of the gap on the outer periphery of the runner 4, when the pressure on the runner upper surface side A is increased higher than the pressure in the inside B chamber, a downward force acts to the pump water-wheel rotary part in the separated state from a dynamotor, due to the water pressure difference between the upper and the lower surface of the runner 4. Thus, floating-up is prevented, and the pump water-wheel runner can be positioned tentatively on a lower cover 11.

IPC: B63B1/24
Filed: 1978-06-29
Abstract: PURPOSE: To reduce the frictional resistance of water to a moving boat, by attaching numerous hydrofoils to the vicinity of the load line of the boat and applying the buoyancy from the hydrofoils to the boat.  
     CONSTITUTION: The numerous hydrofoils 2 are attached to the vicinity of the load line of the boat 1. The top of each hydrofoil is arc-shaped so that the buoyancy is caused by the hydrofoil when the boat 1 moves at a prescribed speed. Since the buoyance is applied to the boat 1, the frictional resistance to the boat is reduced. The rolling and pitching of the boat 1 are held down by the action of the hydrofoils 2. The navigation of the boat is thus stabilized.
