  • Patent number: 6223015
    Abstract: A recording medium carrier system of an image forming apparatus is constituted by independent units as a paper supply cassette, a paper feed unit, a transfer unit, a fixing unit, and a paper ejecting unit. An intermediate transfer unit in the transfer unit is provided with an intermediate transfer belt to which a toner image formed on a photoconductive drum is primarily transferred at a primary transfer position and which secondarily transfers the toner image on a recording medium at a secondary transfer position, and a driving roller for circulating the intermediate transfer belt. The primary transfer position is arranged close to the driving roller.

  • Patent number: 6035154
    Abstract: An image forming apparatus includes a latent image carrier in which an electrostatic latent image is formed on the surface thereof, development unit or units for applying charged developer to the surface of the latent image carrier to visualize the latent image, an intermediate transfer body which is abutted against the latent image carrier, and to which the primary transfer voltage of polarity reverse to the charging polarity of the developer is applied and on which the visible image is primarily transferred, a secondary transfer member which is abutted against the intermediate transfer body through a recording medium and to which the secondary transfer voltage is applied to transfer the visible image on the recording medium, and a voltage applying mechanism for applying the secondary transfer voltage of the same polarity as the primary transfer voltage and larger than the primary transfer voltage in an absolute value to the secondary transfer member in case the secondary transfer is executed, and for applyi

  • Patent number: 5847566
    Abstract: A battery capacity meter and a method for precisely calculating a battery capacity are obtained by measuring a terminal voltage of the battery and sequentially calculating the measured terminal voltages. In a battery capacity meter of the present invention, a calculation process is carried out. After a power source is connected to the battery capacity meter, an initial value S.sub.0 under non-consistent charge state S.sub.i is calculated from an initial value V.sub.0 of a terminal voltage V.sub.i. Next, V.sub.i and S.sub.i are related to a current I.sub.i, and an equation for relating a variation amount .DELTA.S.sub.i of S.sub.i to S.sub.i is formed. Under this relationship, .DELTA.S.sub.i is obtained from V.sub.i and S.sub.i in a time interval .DELTA.t. A value of S.sub.i is updated. Either a remaining capacity or a fuel-gauge normalized remaining capacity are obtained from the updated value of S.sub.i. A process operation is returned to a step where .DELTA.S.sub.

  • Patent number: 5792995
    Abstract: There is provided a harness-fixing construction of a grommet in which an upwardly-extending wire assembly portion can be positively fixed to a tubular portion of the grommet, and the efficiency of a wire harness-installing operation is enhanced. The grommet includes a proximal portion for fitting watertight in a panel hole, the tubular portion of a generally L-shape extending downwardly from the proximal portion, and a protuberance portion which is formed integrally with the proximal portion and the tubular portion, and has a concave surface. The grommet has a passage hole for passing a fastening band (fixing member) therethrough. A holding mechanism for stably holding the upwardly-extending wire assembly portion in a desired position is formed by the passage hole for passing the fastening band therethrough, and the protuberance portion having the concavely-curved surface for holding the upwardly-extending wire assembly portion in a generally embracing manner.

  • Patent number: 5691078
    Abstract: An inexpensive, high precision accumulation type remaining battery capacity meter and method are provided, whereby the remaining capacity of the battery is determined by computing an accumulated discharge value and is displayed in steps on a display unit. The meter includes a memory device with at least one data table relating the terminal voltage of a battery discharging at a predetermined discharge current or discharge power to the remaining capacity of the battery. The data table is used to correct the computed remaining capacity displayed on the display unit. Corrections are only made within a specified range so that abnormal change in the displayed capacity is prevented.
