  • Method and apparatus for punching a thin metal tape to provide a lead frame for a semiconductor device
    Patent number: 5979277
    Abstract: A stripper holder for holding a stripper plate conforms with the deformation of a die plate. A pressing force applied to the stripper plate and is greater than an elastic limit of a metal tape to be punched, and less than a pressing deformation or breakage force of the metal tape. The stripper holder may also be flexible, or such that the metal tape is pressed at two different positions for one punching position by two different pressing forces.

  • Extendable rod antenna and helical antenna with frequency adjusting conductor
    Patent number: 5859617
    Abstract: The invention is directed to an antenna assembly which, when a rod antenna unit is retracted in the radio housing, permits transmission and reception with no influence thereon by the retracted rod antenna unit and which resonates with two frequencies when the rod antenna unit is in its extended position. Feeding metal pipe (9) connected to a secondary antenna (14) formed by a helical antenna element has contact springs (18) for elastic contact with a rod antenna unit (2). When the rod antenna unit (2) is retracted position, the contact springs (18) contact an insulating cover (11) wrapped around the rod antenna unit (2), electrically disconnecting a primary antenna (20) from the feeding metal pipe (9). Hence, only the secondary antenna (14) serves as an antenna without being affected by the primary antenna (20).

  • Haircut method
    Patent number: 5832937
    Abstract: A method for cutting hair which realizes a hairstyle to give a light appearance of movability and vividness by giving natural irregularities to length of the hair. Three different reference lengths are used for one hairstyle. A founding portion of hair is cut by using a shortest reference length, hair of a vector portion is cut by using a middle reference length, and hair of an outer portion that forms an appearance of the hairstyle is cut by using a longest reference length.

  • Puncture-sealing rubber composition
    Patent number: 3952787
    Abstract: A rubber composition comprising a rubber containing a polymer of ethylene-propylene copolymer or ethylene-propylene-diene terpolymer, polybutene and an inorganic filler has an excellent puncture-sealing property. Tubeless tires provided with the rubber composition have a high resistance against the puncture.
