A heater control device includes a temperature detector that detects a temperature of a heated object heated by a heater; an alternating-current power supply for applying an alternating current voltage to the heater; a turn-on ratio decision unit that determines a turn-on ratio of the heater based on the temperature and a target temperature; a turn-on pattern decision unit that determines a partial turn-on pattern, as the turn-on pattern of the heater, which is a pattern of a turn-on ratio higher than the determined turn-on ratio in terms of a control-period, and to which a partial turn-on instead of a full turn-on is allocated on a half-wavelength basis of the alternating current voltage within the control period based on the turn-on ratio of the heater; and a turn-on controller that controls turn-on of the heater based on the determined turn-on pattern.

A powder detector includes a driver to drive a motor, a stirrer to stir powder in a vessel, a vibration plate disposed in the vessel and vibrated by a flip of the stirrer rotated by the motor, and circuitry. The circuitry detects a vibration of the vibration plate, estimates an amount of powder based on a detection result of the vibration, and causes the driver to drive the motor from a starting point, so as to move the stirrer to a preset halt position. The starting point is a rotation angle of the motor on detection of the vibration.

A sheet thickness detecting device for detecting a thickness of a sheet includes a fixed roller rotatably supported by a shaft so that the fixed roller faces the sheet; a movable roller rotatably provided so that the movable roller and the fixed roller sandwich and feed the sheet, and configured to be displaced in accordance with the thickness of the sandwiched sheet; a swing member rotatably supporting the movable roller and including a shaft so that the swing member is swung around the shaft, wherein the swing member further includes a detection target part formed in a manner that a distance between the detection target part and the shaft is greater than that between a position where the movable roller is supported by the swing member and the shaft; and a detecting unit detecting the displacement amount of the detection target part of the swing member.

A recording medium setting device includes a base plate on which recording media are set; guide members being moved in a width direction of the recording media that are set on the base plate; a contact detection unit detecting a contact between the guide members and the recording media; an approach unit moving the guide members in a direction so as to sandwich the recording media set on the base plate until the contact detection unit detects the contact between the guide members and the recording media; and an additional approach unit moving the guide members, moved by the approach unit, at a predetermined distance in the direction to squeeze the recording media after the contact detection unit detects the contact between the guide members and the recording media.
摘要:
A sheet roll (1) is manufactured by placing a sheet-like coupling member (3) on end portions of a plurality of glass films (g) so as to span therebetween, coupling the end portions of the glass films (g) together, and rolling the coupled plurality of glass films (g). The sheet-like coupling member (3) used in the sheet roll (1) includes wide width portions (4) for forming wide joint portions joined to the glass films (g) at each of both end portions thereof in a rolling direction, and a necked portion (5), which is narrower than the wide width portions (4) and is formed at a middle portion thereof in the rolling direction.
摘要:
An electric discharge machine to process a work piece includes a plurality of electrodes, and a plurality of discharge power supply units. The plurality of electrodes generate a plurality of discharges with the work piece, respectively. The plurality of discharge power supply units apply voltages for the plurality of electrodes, respectively and independently.

In a music information database, music information where music pieces and impression words representing impressions of the music pieces and usable as search words when any of the music pieces is to be searched for is registered for a plurality of music pieces. Information collection section collects, from among various information being provided by information source sites, information usable as music-piece-related search words. Registration section registers the words usable as music-piece-related search words, collected by the information collection section, into the database in association with particular music pieces. In this way, it is possible to construct a music information database which permits a music information search therethrough using impression words representing impressions of a music piece, at low cost without taking much time and labor.
