Abstract: A variable resistor with a switch which minimizes appearances of an arc and prevents incomplete contact between contacts of the switch originating from such an arc. The variable resistor with a switch includes a torsion coil spring having one end connected to a movable contact element supported for pivotal motion around a support shaft and the other end connected to a cam member also supported for pivotal motion around the support shaft. When the cam member is pivoted by movement of a slider receiver, a connecting point between the torsion coil spring and the cam member moves across a straight line interconnecting the support shaft and another connecting point between the torsion coil spring and the movable contact element so that a movable contact on the movable contact element is instantaneously brought into or out of contact with a fixed contact to turn the switch on or off irrespective of the speed of movement of the slider receiver.

Abstract: An electrophotographic printer having a photosensitive drum disposed in a body for transferring an electrostatically adhered toner to the lower surface of a sheet, a fixing unit disposed at the downstream side of the photosensitive drum for fixing the toner transferred to the sheet, and a suction conveying mechanism disposed between the photosensitive drum and the fixing unit for conveying the sheet transferred with the toner by the photosensitive drum by sucking the sheet transferred with the toner from above comprising a retaining roller rotatably pressed in contact with the lower surface of the conveyor belt of the suction conveying mechanism. Thus, the printer can positively and stably convey a sheet of all types including an envelope toward the fixing unit when the sheet transferred with a toner image to its lower surface is conveyed while the sheet is sucked from the upper surface.

Abstract: A rotary switch has a synthetic resin substrate on the surface of which a plurality of fixed contacts are arranged in a concentric fashion, and a holder rotatable over the expanse of the substrate, including the fixed contacts. A conductor plate supported to the holder is formed with swelled contacts which act as movable contacts. A rib is positioned so that the conductor plate contacts the rib when the switch is in the off position, thereby lifting the movable contacts from the surface of the substrate. A substantially hour glass shaped slit is used to separate and insulate the fixed contacts. The wide portions of the slit act as reservoirs for conductive wearing powder, thereby delaying a short circuit due to wearing powder accumulation. Thus, the switch alleviates wear of the movable contacts and enhances switching accuracy.

Abstract: A thin film transistor array includes a gate bus and a source bus intersecting with each other at right angles, a thin film transistor pair disposed adjacent to the intersecting point and electrically connected to the two buses. If a short circuit is detected between the two buses, the gate bus or the source bus is severed into a separate portions to eliminate the short circuit. A bypass bus is provided to electrically connect the electrically good severed portions and to the end terminal. Such a bypass bus avoids the need for additional power supply terminals to the opposite ends of the severed bus and facilitates driving the thin film transistor by supplying the power at only one end thereof.
