Abstract: In a method of forming a patterned thin film, first, an etching stopper film and a film to be patterned are formed in this order on a base layer. Next, a patterned first film is formed on the film to be patterned. Next, a second film is formed over an entire surface on top of the film to be patterned and the first film. Then, by removing the first film, an etching mask is obtained from the second film formed on the film to be patterned. The film to be patterned is selectively etched through dry etching using the etching mask. A patterned thin film having a groove is thereby obtained.

Abstract: A hydrogen-fueled engine has an intake valve, a hydrogen supply valve and an exhaust valve, which are operated to open and close relative to a combustion chamber, and a control valve provided in a hydrogen supply pipe to control the output of the engine through the control of the flow amount of hydrogen. This control valve is a pressure control valve to adjust the pressure of hydrogen to be supplied. The hydrogen supply valve is operated by an apparatus of the type capable of adjusting the lift and the valve timing. In this engine, the hydrogen to be supplied to the combustion chamber is controlled on the basis of control signals corresponding to load conditions by both the pressure control valve and the hydrogen supply valve under at least one of either the low-load condition or the high-load condition, and substantially only by the pressure control valve under an intermediate-load condition.

Abstract: Rocker arm clearance removing device wherein a hydraulic adjuster applies torque to a pressure bearing surface at right angles thereto on a curved outwardly extending pressure bearing arm of an eccentric cam which eccentrically supports the rocker arm. Rotation of the rocker arm resulting from the torque causes the rocker arm to come into pressure contact with a valve operating cam and an intake or exhaust valve. An engaging piece can be provided radially extending from the eccentric cam circumferentially spaced from the pressure bearing arm for engaging a swivel stop on the case of the hydraulic adjuster to limit swinging of the eccentric cam and rocker arm during assembly. An arm stopper can also be provided on the case of the hydraulic adjuster to prevent swinging of cam and rocker arm in the opposite direction during assembly.

Abstract: A sealed-type hydraulic lash adjuster having a reservoir chamber holding a hydraulic oil having a molecular weight distribution substantially equal to the molecular weight distribution of the exterior oil surrounding the lash adjuster. The approximate matching of molecular weight distributions of the hydraulic oil within the lash adjuster, and the exterior oil contacting the outside of the lash adjuster ensures that the volume of oil in the reservoir chamber remains substantially constant, as the amount of hydraulic oil passing through the diaphragm of the lash adjuster from the reservoir is equal to the amount of exterior oil passing through the diaphragm into the reservoir chamber.

Abstract: An internal combustion engine includes an engine body having a chamber and an endless transmission member extended around and operatively engaged with a crankshaft and a cam shaft to transmit a rotation of the crankshaft to the cam shaft, the endless transmission member being movable along a closed path of travel in the chamber. A hollow mounting member is disposed in the chamber and has an upper open end and a lower tubular portion. The mounting member is fixed to the engine body through fastening elements secured to an upper portion of a peripheral wall of the mounting member. A tensioner device is disposed in the chamber and includes a tensioner member movably mounted on the engine body, and a hydraulic lock mechanism including a hollow cylinder and a plunger slidably received in the cylinder to define a hydraulic chamber in the cylinder. The cylinder is received in the hollow mounting member and snugly fitted in the lower tubular portion of the mounting member against movement.

Abstract: A valve train for an internal combustion engine includes a mounting member mounted on a cylinder head, and a pair of elongated rocker arms interposed between a camshaft and the mounting member. Each rocker arm has opposite first and second sides facing a camshaft and the mounting member, respectively. The rocker arm has opposite ends held respectively against the camshaft and a respective one of intake and exhaust valves at the first side of the rocker arm. A pair of hydraulic tappets are mounted on the mounting member. Each hydraulic tappet includes an axially-extensible elongated body, and a tubular boot of an elastic material mounted around the body to form an oil reservoir therebetween.

Abstract: A hydraulic lash adjuster of the closed-type including a closed cylinder with a plunger positioned therein defining a hydraulic chamber at the closed end of the cylinder. An annular diaphragm extending between the cylinder and the plunger as a reservoir. A passage provides communication between the reservoir and the hydraulic chamber with a check valve preventing flow from the hydraulic chamber to the reservoir. A passageway extends axially through the plunger and is closed off by means of a soft plug in an area of greater diameter intermediate the ends of the passageway. Retainers hold the annular diaphragm in place with the retainer associated with the plunger extending inwardly to the plunger within the diaphragm to conserve on axial length of the mechanism.

Abstract: Herein disclosed is a secondary air supply control device for use with an apparatus for purifying an exhaust gas of an internal combustion engine. In the exhaust gas purifying apparatus, a secondary air supply system is made to communicate with the exhaust system of the internal combustion engine so that secondary air may be supplied during the running operation of the internal combustion engine to said exhaust system thereby to oxidize and clear the unburned noxious content of said exhaust system. The secondary air supply control device comprises a vacuum-operated secondary air control valve which is disposed midway of said secondary air supply system for controlling the flow rate of the secondary air to be supplied to said exhaust system; and means for controlling said vacuum-operated secondary air control valve during the deceleration and the choking operation at the start of said engine so that the supply of the secondary air to said exhaust system is interrupted.

Abstract: An exhaust gas cleaning system for an internal combustion engine is provided which has an exhaust system including a TWC catalyst. The exhaust gas cleaning system comprises a secondary air supply passage coupled to the exhaust system on the upstream side of the ternary catalyst for supplying secondary air to the exhaust system. A secondary air control valve is positioned in the secondary air supply passage for regulating the flow of secondary air therethrough. The secondary air control valve comprises a unitary valve casing, a valve passage in the valve casing coupled to the secondary air supply passage, and first and second control valves for separately opening and closing the valve passages. The first control valve is closed when the engine is decelerating and the second control valve is closed when the engine is accelerating or operating at high speed, thereby maintaining the TWC catalyst as a reducing atmosphere.

The reed valve devices are mounted on the side surface of the cylinder block, each of which has a reed valve chamber and a reed valve that divides the reed valve chamber into an upstream chamber and a downstream chamber and that is adapted to be opened and closed by the pulsating exhaust gas. The upstream chamber is communicated with the open air via a secondary-air intake pipe, and the downstream chamber is connected to the exhaust port via a secondary-air supply passage.
