Title: Production of carbide dispersed type sliding material
Inventor: HIROMATSU KAZUO
IPC: C22C1/10
Filed: 1989-10-20
Abstract: PURPOSE:To obtain a sliding material in which fine ruggedness in formed in the friction surface and which has a property of accelerating the formation of oil film by forming an Mo-containing metallic material into a specific structure by means of melting by use of a high-density heat source. CONSTITUTION:An Mo-containing metallic material is melted by using a high- density heat source, by which the molten part is formed into a dual-phase structure consisting of an Mo-containing high-hardness carbide and a low-hardness martix. For example, the surface of an austenitic material containing Mo by 6% is subjected to arc melting under the conditions of 180A electric current, 10V voltage, 10cm/min velocity, and 10KJ/cm amount heat input. By this method, a wear resistant material which has a dual phase structure consisting of an Mo carbide having about 101mum size, about 32% area ratio, and about 900Hv hardness and a matrix composed of Fe-Cr-Ni alloy and having a hardness as low as 200 H can be obtained. Since the wear rate of the above carbide is lower than that of the surrounding matrix, this carbide remains in the form of a projecting part in the course of being subjected to friction and forms a rugged surface effectively producing fluid pressure.

Title: Device for controlling quantity of indoor air flow
Inventor: FUKUI SEIJI
IPC: F24F1/02
Filed: 1985-12-03
Abstract: PURPOSE:To control the quantity of indoor air flow to prevent frost formation on an evaporator at a low load so that a fall in the capacity of a heat exchanger and dropping of water to the indoor side can be prevented, by providing an air guider made of shape memory alloy having a circular opening between an evaporator and an indoor fan, and sensing discharge temperatures. CONSTITUTION:An air guider 9 made of shape memory alloy having a circular opening therein is interposed between an evaporator 3 and an indoor fan 7, where said opening is adapted to sense and response to discharge temperatures at a high load and a normal load in such a manner that the size of said opening shown by a broken line is contracted to that shown by a solid line depending on the discharge temperature. Normally, a standard refrigeration capacity is produced with an opening having a size of a solid line, i.e., with certain quantity of air flow. When the discharge temperature goes down, the opening of the air guider 9 is expanded to a size shown by a broken line, making the volume of indoor air flow larger than that of normal operation, as a result, saturation temperatures of refrigerant in the evaporator rises, so that frost formation on said evaporator is prevented.

Title: Device for preventing water hammer and pulsation
Inventor: OSHIMA TOSHIYUKI
IPC: F16L55/04
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a device for preventing water hammer and pulsation simple in principle for absorbing impact and enabling miniaturization of the device itself. SOLUTION: In a diffuser part 4 of a venturi tube 21 provided at the midst of piping 20, an opening part 5 communicated with an atmosphere opening port 7 is provided via a communicating part 6. In the communicating part 6, a check valve 22 constituted of a spherical valve element 8 and spring 9, for instance, is arranged. When a cutoff valve 11 is opened and fluid is made to flow, force due to a pressure difference of the atmosphere opening port 7 and the opening part 5 presses down the spherical valve element 8 against pressing force of the spring 9, air flows toward the opening part 5 and air bubbles 10 mix in fluid. The moment the cutoff valve 11 is closed and flow of fluid is stopped, air bubbles 10 are crushed in the upstream of the cutoff valve 11 and air bubbles 10 expand and absorbs a water hammer action in the downstream of the cutoff valve 11.  In a state that flow of fluid is stopped, the spherical valve element 8 is brought into press-contact with the atmosphere opening port 7 by pressure force of the spring 9 and static pressure of fluid and fluid is prevented from flowing out to the outside of the piping 20.

Filed: 1988-10-28
Abstract: PURPOSE:To obtain a high level output even in the absence of an external pull-up resistor by controlling the operation of a transistor(TR) for a high level output with a control circuit output receiving a control signal and a driving signal. CONSTITUTION:In the absence of an external pull-up resistor, a leakage current of an N-channel MOSFET 12 is measured at an output terminal 3. Moreover, in the absence of an external pull-up resistor at the output terminal 3 an input terminal 1 is fixed at a low level signal at the test. In this case, when the signal at the input terminal 2 changes from a high to a low level, the N-channel MOSFET 12 is turned off, a P-channel MOSFET 11 is turned on and the output terminal 3 changes from a low level to a high level. Thus, a high level output is obtained in the absence of an external pull-up resistor and the test whether or not the function in the inside of an IC is normal is conducted by measuring the level appearing at the output terminal 3.
