摘要:
A light, compact angle-of-rotation sensor is provided that is comprised of a magnetic ring bonded to a shaft by means of resin. The magnetic ring is provided around its periphery with a number of magnetized zones, with each such magnetized zone having a different number of magnetic poles, and magnetic interference between magnetized zones is prevented by leaving non-magnetized spaces between the magnetized zones. The prevention of magnetic interference can be further enhanced by the provision of non-magnetized portions between the magnetic poles of the magnetized zones.

A light, compact angle-of-rotation sensor is comprised of a magnetic ring within which resin is used to fix the ring to the periphery of a shaft. Formed on the magnetic ring are insets into which the resin enters, providing a strong bond between the resin and the magnetic ring. In addition, a key inset into the shaft provides a strong bond between the resin and the shaft. Magnetized zones are formed on the outer surface of the magnetic ring, and magneto electric transducer means are arranged in the proximity of these zones to face said zones, and the angle of rotation is detected from the changes in magnetism that accompany the rotation.

A method of manufacturing an angle-of-rotation sensor comprises fabricating a rotating member by providing a shaft coaxially inside a magnetic ring made of ferrite magnetic material or the like, and filling the space between shaft and ring with resin. As the resin is first provided on the outer surface of the magnetic ring, then in the interior, a balance is achieved between tensile stress from within the ring and compressive stress from the outside of the ring, and as a result the ring is not broken or cracked. Thus, with this method it is possible to make the angle-of-rotation sensor small and light.

An engine starter and electric generator system transmits rotative power to a crankshaft to start an engine and generates electric power based on rotative power from the crankshaft after the engine has started. The engine starter and electric generator system includes a starter/generator operable selectively as a starter motor to produce the rotative power and a generator for generating the electric power, and an electric power supply device for supplying electric power to the starter motor. A power transmitting mechanism operatively interconnects the crankshaft and the starter/generator, for bidirectionally transmitting the rotative power between the crankshaft and the starter/generator. A transmission mechanism is disposed in the power transmitting mechanism, for changing the speed of rotation transmitted between the crankshaft and the starter/generator. The system also has a control device for controlling operation of the starter/generator and establishing different speed-reduction ratios for the transmission mechanism when the starter/generator operates as the generator and when the starter/generator operates as the starter motor.

A distributor accommodates an angle-of-rotation sensor having a magnetic rotating member which is provided to detect the crank angles in an internal combustion engine. The air vent of the distributor is provided with a magnetic trap means that collects any ferrous particles and other such dust in air drawn into the distributor from the outside, preventing such particles adhering to the magnetic rotating member and producing otherwise detection output errors.
摘要:
A substrate processing method and apparatus can securely carry out a pre-plating treatment that enables uniform plating in the necessary area of the surface of a substrate. The substrate processing method carries out a cleaning treatment and a catalyst-imparting treatment of a surface of a substrate as pre-plating treatments and then electroless plates a metal film on the catalyst-imparted surface of the substrate. The cleaning treatment is carried out in a wider area of the surface of the substrate than that area to which a catalyst is imparted by the catalyst-imparting treatment.

摘要:
A substrate processing apparatus can efficiently form, e.g. by electroless plating, an interconnects-protective layer on the surface of a substrate at a low initial cost for the apparatus and a low running cost without the need for a wide installation space. The substrate processing apparatus includes a loading/unloading and cleaning area accommodating a first transfer robot which has a hand adapted for handling a dry substrate and a hand adapted for handling a wet substrate, a loading port which loads a substrate cassette that houses a substrate, and a cleaning unit for cleaning a substrate. A plating treatment area accommodates a second transfer robot which has a back surface-attracting type of hand provided with a reversing mechanism, a pretreatment unit for carrying out pretreatment of a substrate before plating, and a plating treatment unit for carrying out plating treatment of the substrate.
