  • Publication number: 20160076141
    Abstract: A manufacturing method of a hard sliding member of the present invention includes a surface treatment step of surface-treating a surface of a substrate, and a carbon film formation step of forming a carbon film on the surface of the substrate by performing arc ion plating with using a target containing carbon. In the carbon film formation step, formation of the carbon film is started by performing the arc ion plating while introducing a hydrocarbon gas, then an introduction amount of the hydrocarbon gas is reduced and the arc ion plating is continued so as to form an intermediate layer, and a surface layer made of ta-C is formed on a surface.

  • Publication number: 20150299847
    Abstract: An ion bombardment device for stabilizing and cleaning the surface of a substrate. The device includes: a vacuum chamber; at least one electrode that is disposed on the inner wall face of the vacuum chamber and emits electrons; a plurality of anodes that receive the electrons from the electrode and that are arranged so as to face the electrode with the substrate sandwiched therebetween; and a plurality of discharge power sources corresponding to the anodes respectively. Each of the discharge power sources is insulated from the vacuum chamber and provides to the anode corresponding to the relevant discharge power source currents and voltages that can be set independently of one another, thereby generating a glow discharge between such anode and the electrode.

  • Patent number: 9017534
    Abstract: Disclosed is a vacuum deposition apparatus which suppresses mutual interference of magnetic fields generated by multiple magnetic-field applying mechanisms for evaporation sources. The vacuum deposition apparatus includes a deposition chamber; a magnetic-field applying mechanism of sputtering evaporation source disposed in the deposition chamber; a magnetic-field applying mechanism of arc evaporation source disposed in the same deposition chamber; and magnetic-field shielding units arranged so as to cover partially or entirely at least one of these magnetic-field applying mechanisms for evaporation sources (preferably the magnetic-field applying mechanism of sputtering evaporation source). Portions (portions to face a target material upon dosing) of openable units of magnetic-field shielding units are preferably made from a non-magnetic material.

  • Publication number: 20150094908
    Abstract: A laser radar apparatus includes a beam projecting unit and a beam receiving unit that receives via a glass surface a reflective wave occurring when a beam projected from the beam projecting unit is reflected from an object. The laser radar apparatus further includes control unit that commands a prompt operation mode of a wiper when an amount of the objects is determined to be greater than or equal to a threshold level based on a beam reception level detected by the beam receiving unit, and a wiper operation control unit that controls the wiper to operate in the prompt operation mode after a waiting time period elapses. The waiting time period is from when it is detected that the amount of the objects is greater than or equal to the threshold level to when a wiper operation starts.
