According to the stencil making and attaching method of a printing device of the present invention, independent of variations in the detection of the stencil sheet set position detection sensor and variations in the clamped state due to curled stencil sheet, etc., it is possible to always set the image-formation start position of the stencil sheet at a regular position with respect to the drum rotation position, and consequently to improve the positional precision of the printing operation.

A magneto-optical recording medium comprises, on a substrate, a dielectric layer, a GdFeCo reproducing layer, a non-magnetic layer, and a TbFeCo recording layer. Upon reproduction, a DC magnetic field Hex is applied in the recording direction, and a reproducing light beam is radiated while being modulated to have a low power and a high power in synchronization with a reproducing clock. The reproducing layer is a magnetic film which changes from in-plane magnetization into perpendicular magnetization at a critical temperature Tcr, which has a compensation temperature Tcomp between room temperature and a Curie temperature Tc, and which satisfies Troom

A high density optical recording medium having wide-width grooves capable of reliable tracking is provided. The optical recording medium is formed with the wide-width grooves 12 in which a width g of the groove 12 is larger than a width L of a land between the grooves. The lands 11 and the grooves 12 are formed so that a track pitch Tp is less than 1 .mu.m, and a land height h from a groove bottom surface 13 satisfies [(.lambda./(8n)).multidot.Ltan.theta.]/[Ltan.theta.-(.lambda./(8n))].ltoreq.h.ltoreq.[(.lambda./(5n)).multidot.Ltan.theta.]/[Ltan.theta.-(.lambda./(5n))] with respect to a wavelength .lambda. of a reproducing light beam and a refractive index n of a substrate. An angle of inclination of a groove side wall is represented by .theta., and the refractive index of the substrate is represented by n. Even when the width L and the height h of the land is changed due to any optical blur, the disturbance of diffracted light from a land shoulder 19 is suppressed, making it possible to obtain a stable track position control signal.
摘要:
An oil pump for a lubricating system of an outboard motor is disclosed. The motor has a cowling defining an engine compartment, a water propulsion device, and a guide member having an upper surface and a lower surface, the guide member positioned in the cowling and generally dividing the engine compartment into an upper part and a lower part. An engine is positioned in the upper part of the engine compartment within the cowling and has an output shaft arranged to drive the water propulsion device. The lubricating system includes an oil pan positioned below the guide member and an oil passage leading from the pan through the guide member. The oil pump is positioned in the upper part of the engine compartment, but below the engine, and is driven by a lower end of the output shaft of the engine which extends below the engine, the oil pump having an oil inlet in communication with the oil passage through the guide member.

An outboard motor embodying a twin overhead camshaft, four cycle internal combustion engine as a power plant. The engine has an improved flexible transmitter drive for the camshaft, which permits the drive pulley to overly the end main bearings for the camshafts so as to reduce bending loads on them.
摘要:
An outboard motor for a watercraft includes a simply structured fuel supply system of a smaller size and a longer life than prior fuel supply systems. The fuel supply system includes a delivery fuel tank carried by the outboard motor. Fuel is pumped from an external fuel supply tank carried by the watercraft to the delivery fuel tank by a low-pressure fuel pump located within the outboard motor. A control system controls the low-pressure fuel pump so that a predetermined level of fuel is maintained in the delivery fuel tank. The control system includes a fluid level detection sensor that detects the level of fuel within the delivery fuel tank and produces a corresponding signal indicative of the fuel level. A control unit circuit receives the fluid level signal and determines if the fluid level in the tank is higher or lower than a predetermined maximum fuel level. If the fluid level is determined to be higher than a maximum fuel level, the control unit circuit deactivates the low-pressure fuel pump. If the fluid level is determined to be lower than the maximum fuel level, the control unit circuit activates the low-pressure fuel pump.

An outboard motor having a powerhead with a powerhead with a compact internal combustion engine induction system and fuel supply system. The induction system includes a plenum chamber or surge tank that is formed as a housing on an end of the engine opposite to that where the engine induction passage serving the combustion chamber is formed. This common housing also forms passages for carrying fuel between the supply system and the fuel injector including a vapor separator formed integrally in said, housing.
