  • Patent number: 8159827
    Abstract: When U-shape formed electronic components having an axial lead shape are mounted upright on a printed board, two U-shape formed electronic components having an axial lead shape are arranged so as not to be in the same straight line, and a wiring pattern is formed in a state where bent-side lead wires have the same electric potential, and the electronic components are inclined so as to place the bent-side lead wires close to each other, whereby the electronic components that tend to fall in the inclined direction can be mutually supported by the bent-side lead wires. Thus, the electronic components can be prevented from falling without spoiling a heat dissipation performance of the electronic component and the board, and without greatly deteriorating an assembly performance of the board.

  • Patent number: 5916712
    Abstract: A halftone phase shift photomask having a sufficiently high transmittance for light of short wavelength and usable for high-resolution lithography effected by exposure using deep-ultraviolet+radiation, e.g., krypton fluoride excimer laser light. The halftone phase shift photomask has on a transparent substrate a halftone phase shift layer which includes at least one layer composed mainly of a chromium compound. The chromium compound contains at least fluorine atoms in addition to chromium atoms. A transmittance higher than a predetermined level can be obtained even in exposure carried out a relatively short wavelength. The photomask can be used for exposure using deep-ultraviolet+radiation, e.g., krypton fluoride excimer laser light (wavelength: 248 nm). Thus, high-resolution lithography can be realized. Since the photomask can be formed by approximately the same method as in the case of the conventional photomasks, it is possible to improve the yield and reduce the cost.

  • Patent number: 5164935
    Abstract: A magneto-optical disk storage has an erroneous insertion preventing mechanism which projects into a holder so that it can touch the magneto-optical disk cartridge in order to prevent the same from being inserted. The erroneous insertion preventing mechanism mechanically engages with the magneto-optical disk cartridge and moves in a direction approximately vertical to the recording suface of the magneto-optical disk to allow the magneto-optical disk cartridge to be inserted only if the magneto-optical disk cartridge is being inserted into the holder with a correct orientation.
