摘要:
A centrifugal separator comprises a centrifugation chamber, gas inlet ports for introducing a gas into the centrifugation chamber so as to whirl the gas, a clean gas discharge pipe provided on the upper portion of the centrifugation chamber, and a guide member secured to the lower portion of the centrifugation chamber. The guide member has an annular groove, outer fine holes made in the groove, a guide portion projecting conically inward the centrifugation chamber, and an inner hole made in the center of the guide portion. A gas including particles is introduced into the centrifugation chamber, in which the particles are separated. The separated particles are trapped in the groove with gas, then discharged from the outer holes. The clean gas removed of the particles is guided by the guide member to direct to the gas discharge pipe, at the same time the particles with gas toward the guide member also are guided by the guide member to be subjected to the centrifugal force.

To obtain an inexpensive, high-power optical fiber output semiconductor device, an edge emitting type semiconductor element, a tapered optical waveguide having a structure for accommodating expansion and contraction due to a change in temperature, and an optical fiber are prepared separately. One edge of the tapered optical waveguide is butt-joined to an output face of the edge emitting type semiconductor element. The other edge of the tapered optical waveguide is connected to the optical fiber.

A hydraulic supply device of an automatic transmission, which supplies operating oil to the automatic transmission that is able to shift power from an engine and transmit the power to drive wheels of a vehicle by selectively engaging a plurality of frictional engagement devices using hydraulic pressure is disclosed. The hydraulic supply device includes: an accumulator that accumulates operating oil; a leaking flow compensation hydraulic pump that supplies the operating oil for compensating for a flow rate of the operating oil leaking in the automatic transmission to the automatic transmission by being driven by a power source different from the engine when the engine is automatically stopped; and a hydraulic supply control mechanism configured to supply the operating oil accumulated in the accumulator to a starting frictional engagement device that is one of the plurality of frictional engagement devices to be engaged at the time of starting the vehicle when the engine is restarted after the engine is automatically stopped.

Included are an exterior sealing member (20) that is annularly molded using an elastomer; a reinforcing ring (10) that is disposed in a housing hole (B) so as to surround an outer circumference of a rotating shaft (C) and to press a fitting portion (21) of the exterior sealing member (20) against an inner circumference surface of the housing hole (B); a retainer (40) that is mounted in the reinforcing ring (10); an auxiliary sealing member (30) having one end portion that is pinched and retained between the retainer (40) and the reinforcing ring (10) and the other end portion that is pressed against the outer circumference surface of the rotating shaft (C); and an elastic tongue piece (42) and an engagement portion (13) that is provided between the retainer (40) and the reinforcing ring (10). The elastic tongue piece (42) and the engagement portion (13) deform elastically to permit the retainer (40) to be accommodated in the reinforcing ring (10) when the retainer (40) is mounted in the reinforcing ring (10), and the elastic tongue piece (42) and the engagement portion (13) are elastically restored to prevent the retainer (40) from dropping out of the reinforcing ring (10) when the auxiliary sealing member (30) is pinched and retained between the retainer (40) and the reinforcing ring (10).
摘要:
A controller determines a target gear ratio from an accelerator opening and a vehicle speed. The controller determines the stroke of a trunnion on the basis of the difference between present inclination and a target inclination, thereby to control stroke by a hydraulic control valve. The stroke is corrected according to input/output disc pushing force.

Even if there is a temperature variation, a positional discrepancy at a colliding surface of an active surface of a semiconductor laser and an optical waveguide is suppressed, resulting in realization of a semiconductor light emitting element coupled with optical fiber of stable operation. In order to realize the above object, a semiconductor light emitting element coupled with optical fiber comprises a substrate, an optical waveguide disposed on the substrate and including a core and a cladding layer covering the core, a semiconductor light emitting element disposed on the substrate and comprising an output end-surface facing one end of the core of the optical waveguide, and an optical fiber comprising a core an end of which faces the other end of the core of the optical waveguide, wherein the cladding layer sandwiches both surfaces of the semiconductor light emitting element.
