    摘要: An angular position detection device has a rotor that comprises two magnets and a primary yoke, and a stator that comprises a pair of auxiliary yokes and a magnetism detection element. The rotor is fixed to a rotary shaft of an object to be detected. The primary yoke forms a magnetic circuit in a ring, and the magnets are configured so that the intensity distribution of the magnetic field is asymmetric with respect to the center of rotation of the rotor. The magnetism detection element is placed in a gap between the auxiliary yokes. This stator is disposed in the inside of the rotor so that an air gap between the rotor and the stator varies gradually in the circumferential direction. Thus, the magnetism detection element is enabled to produce a linear output over a range wider than 180°.

    摘要: A pneumatic radial tire for motorcycle comprises a belt containing cords extended substantially in a circumferential direction of a tread and has a directional tread pattern defined by plural main slant grooves having a given inclination angle with respect to the circumferential direction and extending from a tread center up to a tread shoulder region and a slant sub-groove arranged between the slant main grooves and having an inclination angle smaller than that of the slant main groove, in which the slant main groove has a given width in connection with a periphery length between both ends of the tread at a particular posture under a given air pressure; a main portion of the slant sub-groove is terminated so as not to open into the slant main groove and has given groove width, length in the circumferential direction of the tread, and depth.

    摘要: In a silicone rubber composition comprising an organopolysiloxane having at least two aliphatic unsaturated groups and a curing agent, thermal black and/or furnace black having a primary particle diameter of 50-500 nm and a DBP oil absorption of 20-50 cc/100 g is blended. There may be further blended an organopolysiloxane having an ionic group-bearing portion as an antistatic agent and/or a hydrocarbon insulating oil. The composition has a stable resistivity in the semiconductive region and thus is useful as semiconductive rolls.

    摘要: The present invention provides a thermocompression tool, i.e. high strength bonding tool used for mounting a semiconductor device or element such as IC, LSI, etc. on a substrate, for example, a tool of pulse heating type used for soldering, and a mounting tool (bonding tool). The tool is used for heating, melting and bonding or thermocompression bonding in a lump a number of workpieces to be bonded, making up a part of electronic parts, in particular, a high precision tool called outer lead bonding tool. The high strength bonding tool has a substrate that is composed of a cemented carbide having microscopic protrusions of hard carbides and/or hard carbonitrides on at least one surface and having a coefficient of linear expansion of 4.0.times.10.sup.-6 to 5.5.times.10.sup.-6 /.degree.C. at room temperature to 400.degree. C. Furthermore, a polycrystalline diamond coating is formed on the surface having microscopic protrusions by a gaseous phase synthesis method, the surface coated with the polycrystalline diamond coating being used as a tool end surface.
