Abstract: A compressor includes a motor driven by a controller and having a rotor and a stator, a compressing unit driven by the motor in a hermetic container in which refrigerant is filled. Driving the motor at a low rpm, the controller practices a feedback control which determines a timing of turning on/off switching elements based on a signal detecting a position of the rotor, and when the motor is driven at a high rpm, the controller practices an open-loop control which outputs a given frequency and drives the motor synchronizing with the given frequency. This structure achieves a compressor working with a fewer noises in PWM driving.

Abstract: An improved cam and follower arrangement suitable for actuating, for example, poppet valves of an internal combustion engine and method and apparatus for forming the cam surface. This permits the use of skewed valve axes without using multiple rocker arms for each valve. The shapes are chosen and formed to provide better contact area and permits the cams to be ground with conventional grinding methods and for multi-cylinder engines.

The optical film laminate comprises an optical film layer 1 and a pressure-sensitive adhesive layer 3, wherein non-tacky powders 5 are adhered to edge surfaces of the pressure-sensitive adhesive layer.

Abstract: A multi-valve internal combustion engine having a plurality of valves having skewed axes that are operated by cam lobes of a single cam shaft. The cam shaft operates the valves through rocker arms each of which are pivoted independently about axes that are skewed relative to the cam shaft axis so as to minimize bending stresses on the valve during its actuation. This also avoids scuffing between the rocker and the valve stem. At the same time, good contact is maintained between the cam lobe and the follower surface by machining the cam lobe so that it will have a slight concavity at least in its tip portion so as to ensure constant line contact with the follower.

Abstract: In a valve drive system, a plurality of intake or exhaust valves are disposed radially in a cylinder, and the intake or exhaust valves each are driven by respective rocker arms supported for rotation on a cylinder head via a rocker pin and an intake or exhaust cam shaft having three-dimensional cams for engaging these rocker arms. A boss of the rocker arm is coupled to the rocker pin for tilting movement in a direction perpendicular to the axis of the rocker pin. The rocker arm is tiltable with respect to the rocker pin to follow the three-dimensional cam surface. The cam surface can be in line contact with the sliding surface of the rocker arm throughout its circumference.
