Title: Near-beta type high strength ti alloy material excellent in fatigue crack propagation property
Inventor: MATSUMOTO TOSHIO
IPC: C22C14/00
Filed: 1995-07-20
Abstract: PURPOSE: To impart excellent mechanical strength, particularly, excellent fatigue strength and fatigue crack propagating resist properties to an alloy material and to apply it to the rotating structure of a jet engine by specifying the compsn. of a Ti alloy and forming its metallic structure into an equiaxial αone. CONSTITUTION: This alloy material has a compsn. contg., by weight, 4.5 to 5.5% Al, 1.5 to 2.5% Sn, 3.5 to 4.5% Zr, 2.5 to 3.5% Cr, 2.5 to 3.5% Mo, and the balance Ti with inevitable impurities and has a metallic structure of an equiaxial α one. The content of Cr in the compsn. is preferably regulated to 2.6 to 3.4%. The formation of the metallic structure into the equiaxial α one can be attained by sufficiently executing hot finish working, e.g. forge-expanding at the β transformation point or below and thereafter subjecting the same to heat treatment at the β transformation point or below. Ordinary, this heat treatment is constituted of solution treatment and aging treatment.

Title: Control device for pneumatic type automatic clutch
Inventor: HISAMURA HARUYOSHI
IPC: B60W10/10
Filed: 1982-10-22
Abstract: PURPOSE:To prevent the lost motion of an engine and its mal-start by adjusting the start pressure depending upon the engine rotating speed signal oil pressure and start adjusting pressure by means of a starting valve and making the start pressure constant independent of the rotating speed during idling. CONSTITUTION:The start pressure pressure-adjusted by a starting valve 116 is supplied to a clutch for advance. The start pressure is proportional to the engine rotating speed signal oil pressure obtained by a Pitot tube 20 and is inversely proportional to the start adjusting pressure obtained by a start adjusting valve 118. The adjusting valve 118 is controlled by a speed change control unit 300. When the engine is idle while a car is being stopped, the valve is controlled so that the start adjusting pressure can correct the variation of the engine rotating speed and the start pressure can always be fixed. When the idling speed is increased, the rotating speed signal oil pressure is increased. Since the start adjusting pressure is also increased based on the command of a control unit 300 and two opposed types of force that are actuated on the starting valve 116 are always fixed, the start pressure is kept constant and a mal-start and such can be prevented.

Filed: 1993-07-27
Abstract: PURPOSE:To easily hold the required delivery pressure constant in a packaged screw compressor by control of a pressure setter without requiring complicated procedures such as varying the size of a pulley and adjustment of a suction throttle valve. CONSTITUTION:A packaged screw compressor having a screw compressor main body 3 and a motor 6 for rotating a screw includes an inverter 18 that supplies AC power to the motor 6, a pressure setter 20 for setting a delivery pressure from the compressor main body 3, a pressure sensor 21 for detecting the delivery pressure from the compressor main body 3, and a PID device 19 that controls the inverter 18 in response to pressure signals from both the pressure setter 20 and the pressure sensor 21 to control the rotation of the motor 6. Therefore, the delivery pressure can easily be set by simple control of the pressure setter and be held at the required minimum constant pressure so as to provide an energy-saving effect.

Title: Semiconductor memory device
Inventor: TSURUOKA SHIGEO
IPC: G11C11/413
Filed: 1984-09-04
Abstract: PURPOSE:To set a through electric current, which flows regularly for the prohibited period, to about zero and to decrease a consumption electric current at the address buffer circuit by setting a transfer gate circuit converting TTL and a MOS level to a non-action condition and prohibiting an address input for a certain constant period, after an address selection is determined. CONSTITUTION:When a memory is in a selecting condition (CE is a low electric current.) and the output 105 of an internal signal generating circuit becomes a low electric potential, an address is designated and Ai is changed, and at this time, an NOR circuit and a clocked inverter are in an action condition and address input signals are propagated to 101, 102 and 103. An address change detecting circuit is operated by receiving an address internal signal which is propagated to 103 and by receiving the output of a detecting circuit, a clock is generated at the internal signal generating circuit. The output 105 of a clock generating circuit becomes from a low electric potential to a high electric poten tial, and then, QP3 is off and QN3 is on and 101 becomes a low electric poten tial and therefore, a through electric current will not flow between VDD and a ground. At the same time, QP4 and QN5 also become off.

IPC: B22D7/02
Filed: 1987-07-27
Abstract: PURPOSE:To improve yield of a product by fitting steel plates at four sides of narrow surfaces of a core material, bringing into contact one side of the wide surface of the core material with the mold inner wall and executing casting. CONSTITUTION:The steel plate 7 is fitted to the four sides A, B, C, D of the narrow surfaces of the flat core l material 3 with welding and also one side of the wide surface E is brought into contact with the bottom pouring ingot mold 1 and hung with the supporting member 2. Next, different kind of the base metal 4 with the core material 3 is poured into the mold 1 through a runner 6. As the one side surface E of the core material 3 is not brought into contact with the molten metal, solidified speed of the molten metal at the front face does not differ from the other surface in the inner surface of the mold so much. Raising of the temp. of the core material 3 is little. Further, as there is no invasion of the air to the gap between solidified shell rapidly cooled and the core material 3, the oxidation of the interface at cracking opening part or sound part is prevented. By this method, the development of defect in the product complex material is prevented. Therefore, the yield of the product is improved.

Abstract: PROBLEM TO BE SOLVED: To shorten the delay of data transfer between computers having object request broker(ORB) and remote procedure calling(RPC) mechanisms by directly transferring data from a physical memory area built in a communication source computer to a physical memory area in a communication party side computer. SOLUTION: A remote direct data transfer means 4 executes remote direct memory access(RDMA) for directly transferring data stored in a physical memory built in its own computer to a physical memory area in a communication party side computer. Both the computers are mutually connected by a system area network(SAN) 5 e.g. and data transfer by the means 4 is executed by using the SAN 5 as a physical communication line. Although conversion into a common data format is always executed before the transmission of normal data, the conversion into the common data format can be omitted when the data expression formats of the transmitting side and receiving side computers are the same.

Abstract: PURPOSE:To discharge molten metal from each hole of one pair of discharging holes at almost equal rate as preventing biased flow for the molten metal and to prevent the mixing of impurity into a product and the remelt of solidified shell by discharging the molten metal from discharging hole as circular flow by inclined projecting members, which project on the peripheral wall of molten metal flowing passage for a molten metal pouring nozzle. CONSTITUTION:At the time of pouring the molten steel 22, which is poured into a tundish 21 from a ladle, into a mold 40, this nozzle prevents effectively the biased flow of molten steel, which develops at the time of adjusting the molten steel flowing rate by shifting a sliding nozzle 26, and eliminates the bad effect caused by biased flow. That is, when the molten steel. which has become to the biased flow, reaches to the inclined wing members 36 arranged at the molten steel flowing passage 15 in the molten steel pouring nozzle 31, a part of the molten steel flow with high speed is weakened by the wing members 36 and also flowed along the upper face of wing members 36, to become to the circular flow. As the circular flow is discharged from each hole of one pair of the discharging holes 34a, 34b as almost equal rate of molten steel, the remelting of solidified shell 41 and the powder inclusion 42 are prevented and the quality of cast slab is improved.
