IPC: H03K19/00
Filed: 1980-05-16
Abstract: An integrated circuit having circuitry for clamping input terminals that remain unconnected after assembly into a system. A transistor is connected to clamp the input terminal to reference potential and provide regenerative feedback to a NAND circuit forming a latch which maintains the transistor on when the input terminal would otherwise be left floating. Alternatively, when the terminal is connected to supply potential, the transistor is maintained "off", precluding loss of power.

Title: Optical semiconductor device
Inventor: ITOU MASANORI
IPC: H01L27/144
Filed: 1984-04-03
Abstract: PURPOSE:To omit the bias power source of an FET, by inserting a light conducting cell on the source side of the FET, and applying the self-bias to the gate of the FET. CONSTITUTION:A light conducting cell PC is inserted to the side of a source S of an FET. The self-bias is applied to a gate G of the FET. Thus the FET is operated. Under the state light hnu is not inputted the cell PC, a deep bias voltage is applied to the gate G of the FET, and the FET is in the OFF state. When the light hnu is inputted, the resistance of the cell PC is decreased, the bias voltage of the gate G of the FET becomes shallow and the FET is turned ON. Thus the detected output of the light is obtained at an output terminal OUT.

Abstract: PURPOSE:To save developer and to reduce power consumption by providing a potential application means that applies potential to a photosensitive body during a non-image period. CONSTITUTION:A drum bias is applied to the photosensitive drum 1 from a constant voltage transformer 9. In this case, the potential of the drum is controlled by the constant voltage transformer 9.

Also, at the same time, the constant voltage transformer 9 is turned on, and a drum bias is applied to the photosensitive drum 1. This application continues until the main motor is turned off, that is, until the rotation of the photosensitive drum 1 stops. Thus, during the non-image period in which electrification is not carried out, the potential having the same polarity as that of developer is applied to the photosensitive body, the area where the development means acts on it.

Title: Synchro-mesh for gear type transmission
Inventor: YAMANE NORIHIDE
IPC: F16H3/12
Filed: 1988-03-23
Abstract: PURPOSE:To make the advancing action of a sleeve smooth as large stop ability is insured by inclining at least the one side of surfaces of each cone in two stages, and forming the other side of its surfaces of an elastic material layer. CONSTITUTION:A peripheral cone surface 25B of a clutch gear 25 is inclined in two stages, and an elastic material layer 29 is made to adhere to an inner peripheral cone surface 27A of a synchronizer ring 27 to form a frictional layer. Thus the elastic material layer 29 is compressedly deformed during synchronizing action to increase a frictional contact area between the synchronizer ring 27 and the clutch gear 25, and restored to its original state when the synchronizing action has ended to sharply reduce the frictional contact area. The sleeve 22 can therefore be smoothly advanced to a position where it meshes with the clutch gear 25 after the completion of the synchronizing action as large stop ability for the synchronizing action is insured.
