摘要:
A power transmitting device includes a front housing member, an inner shaft, and a main clutch that selectively permits and shuts off transmission of torque between the front housing member and the inner shaft. The power transmitting device is rotatably supported by a bearing arranged outside the front housing member. An intermediate member having a thermal expansion coefficient lower than the thermal expansion coefficient of the front housing member is arranged between the front housing member and the bearing.

A method of slip casting using a casting mold provided with a water-absorbent layer that has a self-water-absorbent ability, substantially has a water resistance, and is controlled in the saturated water content thereof, the slip casting being conducted by employing mainly a capillary sucking force as the driving force of the water-absorbent layer of cast formation. An open-cell porous body usable as the water-absorbent layer is produced by agitating a mixture comprising a compound having at least one epoxy ring in its molecule, a curing agent which cures the epoxy compound by reaction, a filler developing for a self-water-absorbent ability and a mold release property, and water to prepare an O/W emulsion slurry and curing the slurry, as such in a hydrous state.

A method for preparing high strength and high thermal shock-resistant china for ceramic whiteware which comprises the steps of molding a china-forming raw material which mainly comprises a natural ore material capable of forming corundum through firing or a material obtained by calcining the natural ore material to form corundum, a natural ore material capable of forming mullite through firing or a material obtained by calcining the natural ore material to form mullite, a clayey material and a flux such as feldspar, nepheline or dolomite; and then firing the molded china-forming raw material. The method permits the production of cheaper china for ceramic whiteware having high strength and excellent thermal shock resistance as compared with those prepared by the conventional techniques.
摘要:
A hydraulic control system of an automatic transmission during a shift operation wherein a control pressure is controlled to selectively engage and release a plurality of frictional elements to establish a desirable shift stage comprising inertia phase detecting device for detecting a starting point of an inertia phase of the shift operation from one shift stage to another, and control pressure reducing device for gradually reducing the control pressure introduced to a frictional element to be engaged after the inertia phase is detected. The torque shock in the shift operation can be effectively reduced.

A mold for pressure-cast-molding a ceramic article having a filter material made of an open-cell porous material. The open-cell porous material is prepared by stirring a mixture of a resin material, a microballoon, a curing agent and water to provide an emulsion slurry, casting the slurry in a water-impermeable mold and curing the slurry in the water-containing state. The portions occupied by the water during the preparation of the porous material mainly form open pores.

In a switching circuit formed as an integrated circuit, a series circuit comprising a diode (D.sub.1) and a resistor (R.sub.1) is connected between a base and an emitter of an npn transistor (TR.sub.1) requiring a high speed switching operation. Therefore, a high speed operation is made possible. Furthermore, in a circuit constructed such that the above npn transistor is driven by a pnp transistor (TR.sub.3, TR.sub.4), a leakage current produced in the above pnp transistor at high temperature is allowed to flow in the above series circuit. Accordingly, a malfunction of the above npn transistor is prevented. Consequently, an integrated circuit operable even under high temperatures is achieved.
摘要:
A throttle valve operating cam of an automatic transmission and an output control member of an automotive engine are interconnected so as to cooperate with each other by a cable consisting of an outer tube and an inner cable. The inner cable is connected to the throttle valve operating cam and the output control member and one end of the outer tube is connected first to the automatic transmission. The other end of the outer tube is regulated in position relative to a cable fitting member secured to the automotive engine and then fixed to the cable fitting member secured to the automotive engine.
摘要:
A method of producing a porous material having open pores comprises the steps of preparing an emulsion slurry by vigorously agitating a mixture comprising a main ingredient, a polyamide hardener, a filler and water, casting said emulsion slurry in a water-impermeable mold, hardening said slurry while it contains the water. The main ingredient is a bisphenol-type epoxy resin added with one or more reactive diluents each having one or more epoxy rings per molecule and added in an amount of 18 to 50 wt %, based on 100 wt % of said bisphenol-type epoxy resin. A large size molded product having a high wet bending strength and a complicated contour can be produced.
