A valve operating apparatus, which transmits the rotation of the crankshaft of an automotive engine to the intake and exhaust valves to open and close the valves, can selectively vary the timing to open and close the valves and ther lifts of the valves. The valve operating apparatus includes a camshaft with low- and high-speed cams and low- and high-speed rocker arms, one of which is fixed to and the other rotatably supported on a rocker shaft. The valves can be opened and closed by the low-speed rocker arm. The other rocker arm and the rocker shaft can be engaged and disengaged by an engaging mechanism that is actuated by an actuating mechanism depending on the operating condition of the engine.

An electrostatic motor for use as a power generating mechanism to be mounted on a micromachine includes a rotatable semiconductor substrate and a drive electrode disposed in proximity to the substrate. The semiconductor substrate is doped with a specified impurity element to form electromagnetic wave-static electric converters of p-n junction. When the motor is to be started, the converter in the vicinity of the electrode is irradiated with electromagnetic waves to set up an electric field between the opposed surfaces of the converter and the electrode to rotate the substrate by an electrostatic force due to the electric field.

摘要:
The ferrule of the prior art requires an assembling process, high accuracy machining of the fitting portion, machining of the insert to achieve concentricity, machining of the cone and machining of the outer diameter with a high accuracy. This has been making a factor that increases the production cost of the ferrule which is required to have lower price. The present invention provides an ferrule comprising an insert of substantially cylindrical shape that has a fine hole for housing an optical fiber in the axial direction, and an ferrule body made of a resin for accepting the insert fitted therein, characterized in that: the ferrule body has a through hole made in the axial direction thereof, and the through hole communicates with the fine hole of the insert via a tapered hole, with concentricity between the fine hole of the insert and the periphery of the ferrule body being within 10 &mgr;m.
摘要:
A valve system for an automobile engine opens and closes intake and exhaust valves by reciprocative force of a crankshaft. Specifically, the valve system controls timing for operating and stopping these valves, and the amount of cam lift. The valve system comprises a camshaft, a rocker shaft in parallel to the camshaft, a main rocker arm mounted on the rocker shaft, a sub-rocker arm pivotally supported on the rocker shaft, engaging means for engaging and disengaging the rocker shaft with and from the sub-rocker arm, and driving means for driving the engaging means. The engaging means includes an opening on a rotating surface of the sub-rocker arm, a plunger located in the rocker shaft and an oil chamber located at an upper or lower end of the plunger. The driving means includes an oil gallery in the rocker shaft and an oil pressuring member.

A vehicle equipped with four-wheel drive has a transfer case including a center-differential which delivers driving power to both front and rear axle assemblies when needed and is shiftable between a two-wheel and a four-wheel drive mode of operation and between a differential-locked and a differential-unlocked drive mode of operation. A free wheeling drive mechanism with a clutch member is incorporated in an output shaft of an axle differential in association with wheels non-driven in the two-wheel drive mode of operation and is adapted to disconnect when the vehicle is in the two-wheel drive mode of operation. A controller causes a forced drive mode shift of the center-differential from the four-wheel differential-underlined drive mode of operation either to the four-wheel differential-locked or to the two-wheel drive mode of operation when the disconnection of the free-wheeling drive mechanism is detected while the vehicle is in the four-wheel differential-unlocked drive mode of operation.

A structure of internal combustion engine comprises a cylinder member composed of a cylinder which accomodates a piston connected with a crankshaft, a crankcase provided to accomodate said crankshaft, a rocker case provided to accomodate a valve actuating mechanism, an oil return passage constituting means for leading oil in said rocker case into said crankcase, and a restraining means for restraining an air flow within said crankcase from entering into said oil return passage constituting means. By the effect of the restraining means provided in relation to the oil return passage constituting means, the air flow generated by the rotation of the crankshaft does not work as a dynamic pressure of hingering the flowingdown of oil.

A multi-ocular three-dimensional image reproducing apparatus reproduces a three-dimensional image by reproducing a plurality of light rays passing through a reproduction position of the three-dimensional image by means of a plurality of different parallax images, with a traveling direction of the light rays as a viewing direction. The apparatus includes a controller that coordinately controls a viewing direction of each of the parallax images, a position and size of a display region on a parallax image display device, and irradiation position, irradiation number and irradiation direction of the light rays reproduced by means of the parallax images.
摘要:
The cylinder head of an internal combustion engine according to the present invention comprises a head base portion and an extended head portion connected to the head base portion. The extended head portion allows to arrange a variable valve timing mechanism in the cylinder head of the present invention, together with the valve system of the engine itself. The head base portion has the same interior as that of a prior cylinder head of DOHC type and a height equal to that of an another prior cylinder head of SOHC. The DOHC and SOHC cylinder head can be processed in a common manufacturing line whereby the head base portion can be also processed in the common manufacturing line.
