Title: Overload preventer for hydraulic shovel
Inventor: AIRA TATSUO
IPC: E02F9/22
Filed: 1987-06-30
Abstract: PURPOSE:To prevent the floating of vehicular body by a method in which the head pressure of boom cylinder and the position of bucket are detected, and when load beyond a set value occurs, the operating oil of head is relieved. CONSTITUTION:The oil pressure of the head 71 of a boom cylinder 7 is transmitted through a return oil path 8 and a pressure switch 9. The position of a bucket is calculated in a controller 4 from angles detected by a boom angle sensor 3A and an arm angle sensor 6. In the controller 4, in case the head pressure of the boom cylinder is overloaded, a solenoid valve 10 provided for the return oil path of the boom cylinder is opened to allow excess oil pressure to escape to a tank 12. The controller 4 is also connected to an excavation mode switch 13 to switch overload to light, medium, or heavy. The floating of the front wheel can thus be prevented.

The web part is thereafter sintered at 1,100 deg.C for about 1hr in gaseous N2. Fine powder particles 14 having about <44mu grain size are put into such sintered body 12 and are sucked by a vacuum through a filter 15, by which the fine powder particles 14 are packed into the internal spaces of the sintered body 12. Flange parts E and D are then separately formed by compacting coarse-grained powder 14 as a raw material. A space 18 is disposed therebetween and the flange parts are joined to the sintered body 12 and the assembly is compacted and sintered as the connecting rod. The spacer 18 is thereafter removed and the connecting rod consisting of the web C and flanges DE which are equal in strength is produced.

Inventor: MIURA TAKASHI
IPC: D01F6/76
Filed: 1984-08-02
Abstract: PURPOSE:To prepare a hollow yarn like semipermeable membrane having a sharp fractionating property and high in filtering efficiency and fractionation efficiency, by stretching a hollow yarn so as to adjust the inner diameter thereof to 85% or less of that at the time of the emission of the hollow yarn. CONSTITUTION:A 10-40% solution of a polysulfone resin in an org. solvent having compatibility with water is extruded into a coagulation bath from a ring shaped nozzle. The size of the inner die of the ring shaped nozzle is set to 1.18 times or more of the inner diameter size of a hollow yarn membrane to be obtained. By accelerating the wind-up speed in a coagulation bath, the hollow yarn membrane is stretched so as to adjust the inner diameter to 85% or less of that at the emission time of the hollow yarn membrane. By performing the stretching prior to perfectly gelling the resin, fine pores having an extremely uniform size are formed to the inner surface of the hollow yarn and further fixed in a more finely pulverized state by gelling.

Abstract: PURPOSE:To form a signal processing circuit applying expansion of synchronizing signal integrally with other circuit in an IC by allowing an input circuit to amplify a video signal by a common amplifier, amplifying a horizontal synchronizing signal by other amplifier and synthesizing both the signals. CONSTITUTION:An amplifier 21 comprising transistors (TRs) Q1, Q2 amplifies a horizontal synchronizing signal VS. An amplifier 22 comprising TRs Q3, Q4 amplifies a video signal VV.

Abstract: PURPOSE:To increase detection points and improve the accuracy of detection by irradiating the light emitted from a rotor to a photoelectric member on a stator, and obtaining the change in the electromotive force thereof as angular speed information from a pair of comb-shaped electrodes. CONSTITUTION:A rotor 1 made of acrylics having reflection surface 3, 4a, 4b is fixed to a revolving shaft 2. The light emitted from a lamp 5 passes through the inside of the rotor and is irradiated from light output parts 6a, 6b to the annular photoelectric member 8 on a stator 7. the stator 7 is an insulator and the member 8 is, for example, a solar battery or the like. A pair of comb-shaped electrodes 9a, 8b are formed concentrically to the member 8 on an insulation base plate 7. Since the comb-shaped parts 11, 12, 14 of the electrodes 9a, 9b are connected to the member 8 alternately, an output is taken out from the electrodes only when the light is irradiated simultaneously to one of the comb teeth of the electrode 9a and the adjacent tooth of the electrode 9b. In this way, the revolution can be converted to pulses. It is possible to increase detection points by increasing the comb teeth, or increasing the detecting parts in many plies concentrically.

Abstract: PURPOSE:To prevent the generation of warpages and cracks at the time of the bonding of an insulating member and a heat dissipation member by a method wherein a soft metal or a soft alloy having a high plastic deformability is interposed between the insulating member and the heat dissipation member as a buffer material. CONSTITUTION:In order to dissolve cracks and warpages due to a thermal stress, which is generated in a cooling process at the time of soldering, it is effective that a specified thermal stress buffer material is interposed between an insulating member consisting of Al nitride and a heat dissipation member being constituted of a copper-tungsten alloy or a copper-molybdenum alloy as its main material. The buffer material consists of one of a soft metal and a soft alloy, which have a high plastic deformability, so that the buffer material itself relaxes a thermal stress, which is generated by a difference between the thermal expansion coefficients of the insulating member and the heat dissipation member in the cooling process at the time of soldering, by deforming plastically. It is desirable that the buffer material consists of one of copper, a copper alloy, nickel and a nickel alloy.
