  • 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: 9157998
    Abstract: A laser radar device has a light projection part that projects light to a monitoring area outside a vehicle from a vehicle interior through a glass surface, a light receiving part that is placed a given distance away from the light projection part in a substantially horizontal direction to receive reflected light from an object outside the vehicle in the light projected by the light projection part through the glass surface, a measuring part that measures the distance to the object in the monitoring area based on timing when the light projection part projects the light and timing when the light receiving part receives the reflected light, and a light-projection shielding part that shields the light projected to an outside of the monitoring area in the light projected by the light projection part.

  • Publication number: 20150185320
    Abstract: A laser radar device includes: a projection part repeatedly performing processing of projecting measurement light that is of a pulsed laser beam to a predetermined monitoring area in a measurement period having a predetermined first length, the processing being repeated in c cycles (c?2) in a detection period having a predetermined second length; a light receiver including n1 (n1?2) light receiving elements and receiving reflected light of the measurement light in directions different from one another; a selector selecting light receiving signals of the n1 light receiving elements in each measurement period and output n2 (n2?2) light receiving signals; a sampling part sampling the light receiving signals output from the selector s (s?2) times every time the measurement light is projected; and a detector performing processing of detecting an object in a detection-period-based period based on sampling values.

  • 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.

  • Patent number: 4679952
    Abstract: A printing apparatus wherein character data to be tabulated is input. Data representing the printing position of a specified digit of one piece of character data is input in a tab memory. Then, data designating a tab operation is supplied to an address converting circuit. In accordance with this data, the address converting circuit converts the addresses of the pieces of character data such that the specified digit of every piece of character data is printed at the position represented by the data stored in the tab memory.
