  • Publication number: 20170207718
    Abstract: A power converting device includes: a rectifying circuit connected to an alternating-current power supply for converting alternating-current power from the alternating-current power supply into direct-current power; a short-circuit unit constituted by a diode bridge and a short-circuit element connected to opposite output ends of the diode bridge for short-circuiting the alternating-current power supply via a reactor; and a control unit that generates plural drive signals to control the short-circuit unit during a half cycle of the alternating-current power supply. The control unit generates a sine-wave-shaped current control range that is a target control range of power supply current of the alternating-current power supply, and maintains values of the power supply current of the alternating-current power supply within the current control range.

  • Publication number: 20170149352
    Abstract: A power conversion device includes a rectifier circuit that converts an AC power from an AC power supply, into a DC power, a short-circuit unit that short-circuits the AC power supply via a reactor connected between the AC power supply and the rectifier circuit, a control unit that generates a plurality of drive signals to control the short-circuit unit in a half cycle of the AC power supply, and a smoothing capacitor. The control unit stepwise varies threshold values that limit a value of a power-supply current of the AC power supply, in an on-section or an off-section of the plurality of drive signals.

  • Patent number: 8944557
    Abstract: A recording apparatus includes conveyance roller pair disposed on the upstream side of a recording unit. An image formation operation is forbidden once the trailing edge of a recording medium has passed the conveyance roller pair, to reduce margin amount at the trailing edge of the recording medium. In a case where determination is made that the distance from the trailing edge of the recording medium to the conveyance roller pair is smaller than a first conveyance amount, the recording medium is conveyed by a second conveyance amount which is smaller than the first conveyance amount, so that the trailing edge of the recording medium is on the upstream side of the conveyance roller pair and that the distance from the trailing edge of the recording medium to the conveyance roller pair is smaller than a predetermined distance.

  • Patent number: 8894065
    Abstract: The present invention provide a printing apparatus and a method for conveying a sheet wherein generation of noise is minimized using a simple configuration, wherein, during sheet discharging, a sheet is discharged at a speed suitable for the sheet discharging, and wherein the sheet is aligned at a sheet discharging position. The printing apparatus controls conveyance of sheets as follows. A first sheet and a second sheet fed subsequently to the first sheet are conveyed at a relatively low conveying speed until an upstream trailing end of the first sheet is placed at a sheet discharging standby position. Then, the first sheet is discharged to the sheet discharging position, and the first sheet and the second sheet are conveyed at a relatively low conveying speed until a downstream leading end of the second sheet is placed at a sheet feeding control position.

  • Publication number: 20140287124
    Abstract: Provided is a method of producing a feed or food product in which an inner layer is encrusted with a gelled outer layer composition, the method including the steps of: preparing an outer layer composition feedstock by adding a secondary feedstock to a protein feedstock and/or a starch feedstock that forms a gel upon heating and then mixing by stirring, and preparing an inner layer composition that is encrusted with the outer layer composition; extrusion molding with an extruder provided with a double nozzle so as to cover a surface of the inner layer composition while simultaneously gelling the outer layer composition feedstock by heat treatment; and cutting a continuously extruded cylindrically shaped product to a fixed length with a shutter mechanism while simultaneously encrusting a cut surface with the gelled outer layer composition.
