Patent JP-S61168967-A (JP)
Title: Semiconductor device
Inventor: YAMADA TAKAHIRO
IPC: H01L29/772
Filed: 1985-01-22
Abstract: PURPOSE:To obtain a static induction transistor (SIT) having ideal current saturation characteristics, by providing a first gate region near the source region of a channel and a second gate region near the drain region. CONSTITUTION:An N<->-type well 102 is provided on a P-type substrate 101. An N<+>-type source region 103, an N<+>-type drain region 104, a P<+>-type first gate region 105 and a second gate region 106 are provided on the inner surface of the well 102. There is formed a saddle-point-type potential barrier by the first gate region 105. The potential barrier of the inherent gate region 112 is controlled only by the static induction effect of a voltage applied to the first gate region 105. Since the shielding effect of the second gate region 106 ensures the independency to the drain voltage, ideal saturation characteristics can be obtained while maintaining the high transconductance of an unsaturation- type SIT.

Title: Flip-flop circuit
Inventor: TANAKA HIROSHI
IPC: H03K3/286
Filed: 1978-02-02
Abstract: PURPOSE:To make it possible to generate an output in a preset state even in case of driving a flip-flop circuit while unable to determine its operation, by making different base-emitter voltages of transistors constituting the circuit. CONSTITUTION:When set-reset input signal inversion S and inversion R which are inhibited by a normal set-reset flip-flop circuit are both in an input state, ''0'', base- emitter forward voltage VBE(11) of emitter electrode E11 of multi-emitter transistor Q102 is higher than voltage VBE(21) of emitter electrode E21. As a result, when clock signal (phi) changes from a high potential to a low potential and the flip-flop consisting of Q102 and Q202 becomes stable, Q202 is turned ON  earlier than Q102. Therefore, the preset state, namely, ''1'' as X and ''0'' as inversion X are outputted.

IPC: B60L3/08
Filed: 1995-01-27
Abstract: PURPOSE: To give an alarm by deciding whether or not a driver performs avoidance operation by deceleration operation and the signal of deceleration when turning car speed and actual car speed before entering a curve are compared and a sharp curve is judged and predicting the possibility of deviation from a lane when the driver does not perform avoidance operation. CONSTITUTION: A curve is detected accurately before entering the curve by a curve detecting means 41. Turning car speed is arithmetically operated on the basis of the radius of curvature and the width of a lane, turning car speed and actual car speed before entering the curve are compared by a sharp-curve detecting means 44, and a sharp curve, in which there is the possibility of deviation from the lane, is judged precisely when actual car speed is larger than turning car speed. Whether or not a driver conducts avoidance operation by an accelerator and a brake is judged by a lane-deviation judgment means 45. When avoidance operation is not performed and car speed remains high, the possibility of deviation from the lane is predicted before entering the curve, and an alarm is given and the attention of the driver is called.

IPC: G03G15/20
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a fixing cleaning device constituted so that a cleaning roller and a blade are not locked by toner with extremely simple constitution.

Filed: 1992-01-27
Abstract: PURPOSE:To deal with the reduction of pattern width and a gap by letting magnetic flux flow along a direction in contact with a pattern to be read. CONSTITUTION:A magnetic semiconductor element 11 and a magnet 13 are interposed between terminal parts 2a of a pair of magnetic path members 2, a gap 3 faced to a pattern P to be read is provided between other terminal parts 2b, and a non-magnetic member 4 is interposed. Then, the gap 3 and the non-magnetic member 4 are moved along the surface of sheet paper or the like. When the moving gap 3 and non-magnetic member 4 arrive at a position faced to the pattern P to be read, magnetic flux B flowing in the non- magnetic member 4 while losing magnetism up to the moment flows through the pattern P having high permeability and the loss of the loop of the magnetic flux B is reduced. Then, the magnetic flux B to be detected by the magnetic semiconductor element 11 is increased and the pattern P is read. In this case, the gap of the pattern P to be read is made narrower than conventional by selecting the magnetic field intensity of the magnet 13.

Title: Program loading system
Inventor: ISHIHARA KENJI
IPC: G06F9/445
Filed: 1989-01-20
Abstract: PURPOSE:To reduce hardware quantity for initial program loading by repeatedly writing read data from a read only memory to a storage device and loading the data from the read only memory to the storage device. CONSTITUTION:In the instruction arithmetic processing unit of a system which executes processing with addressing one instruction, an initial program stored in a read only memory (ROM) 1 is written to one part of a data register (MDR) 3 of a storage device (RAM) 2 for loading the program. Then, for example, a non-processing (NOP) instruction is set to the remained area and after that, the contents of the MDR 3 are repeatedly written to the RAM 2 as the read data from the ROM 1. Then, the data are loaded from the ROM 1 to the RAM 2. Thus, with the small quantity of the hardware such as the addition of a circuit to fix and set the NOP instruction to one part of the MDR 3, the program can be loaded from the one instruction word length of the ROM 1 to the plural instruction words length of the RAM 2.
