Title: Inclined function type heat resisting panel
Inventor: MIYAZAKI SHUNICHI
IPC: C04B30/00
Filed: 1990-01-16
Abstract: PURPOSE:To prevent warp by constituting one surface only out of the ceramics members having different thermal expansion coefficients and setting the mixing ratio so that the thermal expansion coefficient may reduce from the vicinity of the center, and constituting the other surface only out of the metals having different thermal expansion coefficient so that the thermal expansion coefficient may increase from the vicinity of the center. CONSTITUTION:A heat-resisting panel 1 is formed by arranging and joining hexagonal plates which are constituted of first and second ceramics members a6 and f6 having different thermal expansion coefficients and first and second metals a1 and f1 having different thermal expansion coefficients, while one surface of the plate is constituted of ceramics member only, and the thermal expansion coefficient is gradually reduced toward the periphery from the vicinity of the center. The other surface is, constituted of the metal plate only, and the thermal expansion coefficient is gradually increased toward the periphery from the vicinity of the center. The ratio between ceramics and metal is made equal in the vicinity of the center in the thickness direction. Accordingly, warp is reduced, and the generation of crack is prevented.

Patent JP-S4886210-A (JP)
IPC: F16D65/28
Filed: 1973-01-17
Abstract: This invention relates to a railway car hand brake apparatus having a spring-biased friction clutch to provide for automatic change from high to low speed drive of a driven member by a drive member upon engagement of the brake shoes with the tread surface of the corresponding wheels in response to the manual rotation of a hand brake wheel. Until the brake shoes engage the tread surface of the wheels, the driven member, which carries thereon a drum upon which a hand brake chain is wound, is driven at fast speed through the friction clutch from the drive member that constitutes a drive shaft and a hand wheel keyed thereto. Slippage of the clutch occurs upon the shoes engaging the tread surface of the wheels, whereupon the drum is driven at a slow speed through a gear train interposed between the driven member to which the drum is keyed and the drive shaft.

Title: Air conditioner
Inventor: OTSUKA SHINJI
IPC: F25B13/00
Filed: 1993-01-20
Abstract: PURPOSE:To prevent an oil level in a compressor from going down even if operation of one of indoor units is stopped in a multi air conditioner in which a plurality of indoor units are provided. CONSTITUTION:In a multi air conditioner, refrigerant discharged out of an outdoor unit 1 is supplied through a distributor 2 to a plurality of indoor units 3A and 3B. It can be selected arbitrarily to operate both of the indoor units 3A and 3B simultaneously or to operate only either one of them. Inside the distributor 2, opening and closing valves 8a and 8b and a capillary tubes 9a and 9b are provided corresponding to the indoor units 3A and 3B. The capillary tubes 9a and 9b operate in response to start and stop of the indoor units 3A and 3B to open or close a refrigerant circuit. If operation of only one of the indoor units, for example, 3B is stopped during the operation of both indoor units 3A and 3B, oil stays on the indoor unit 3B side along with the refrigerant, and thereby an oil level in a compressor 4 goes down. In order to prevent such a going down of the oil level in the compressor, a bypass circuit comprising a capillary tube 10 is provided between outlets of the opening and closing valves 8a and 8b.

Title: Flaw detector by infrared ray detection
Inventor: MAEDA KENSAKU
IPC: G01N21/954
Filed: 1982-01-22
Abstract: PURPOSE:To inspect flaws or defects by bringing fluid of temp. differing from the surface temp. of an object to be inspected into contact with the object to be inspected and detecting the infrared (IR) rays released from the surface of said object. CONSTITUTION:The surface of an object 3 to be inspected is cooled with cooling air from a fan 2 to decrease the temp. thereof. Since the defect 6 of the object 3 is thin in the wall thickness thereof, the thermal resistance and heat capacity in said part decrease and the defect receives the thermal influence of a heat accumulating medium (a heat source for holding the temp. of the object 3) 7 earlier than in the parts having normal wall thickness, thus the surface temp. therein is risen. The surface temp. thereof is monitored with an IR sensor 1 whereby the defective part 6 is detected.

IPC: H03F3/19
Filed: 1982-01-20
Abstract: PURPOSE:To eliminate oscillation when an amplifier is not in use and to save electric power by performing switching between a function for deciding on whether a signal passes through or by-passes an amplifying circuit and a bias for operating the amplifying circuit through the operation of the same switch. CONSTITUTION:For a signal having a low level, terminals 1-3 and 1'-3' are connected together through the switching of the changeover switch SW4 to interpose resistances 5 and 6 in series between a power source VCC and a ground point through the terminal of the SW4, and then an amplifying transistor TR3 is applied with a prescirbed bias to start amlifying the input signal from the terminal 1, thereby outputting the resulting signal from a terminal 2. For a signal having a high level, terminals 1-2 and 2'-1' are connected through the switch SW4 and then the input signal by-passes the amplifying circuit and is outputted from the output terminal. In this case, the amplifying circuit is placed in a cut-off state by disconnecting the resistance 5 to eliminate oscillation, thereby saving electric power.
