Title: Surface treatment method of semiconductor
Inventor: KETSUSAKO MITSUNORI
IPC: H01L21/26
Filed: 1991-05-16
Abstract: PURPOSE:To restrain carriers from being recombined on the surface of a semiconductor. CONSTITUTION:A silicon oxide film which contains nitrogen at an atomic ratio of 5% or higher is applied onto a substrate by a photo-assisted CVD method which uses a low-pressure mercury lamp as a light source. A potential with respect to electrons is lowered on the surface of a semiconductor by a stable positive fixed electric charge formed in a dielectric film; a trap level at the interface between the semiconductor and the dielectric film is occupied by the electrons. On the other hand, the concentration of holes near the interface is lowered. As a result, the recombination speed of carriers is reduced, and an effective surface passivation can be realized.

Title: Delay circuit
Inventor: MORISUE KAZUNARI
IPC: H03K17/28
Filed: 1981-07-15
Abstract: PURPOSE:To prevent malfunction due to a transient noise, and to speed response during testing and in case of emergency, by adjusting a delay time according to the level of an input voltage. CONSTITUTION:An input voltage VIN applied to an input terminal IN is lower than a set voltage VS1 normally, and VIN<VC1. Therefore, the output of a comparator CP1 is at a level H and an NPN transistor TR turns on to charge a capacitor C2 to a charging voltage VC2 through a resistance R9. Initially, VS1<VC2, so the output terminal OUT of a comparator CP2 is at a level H. When the voltage VIN rises until VS1<VIN<VC2 where VS1 is the 1st warning state, the output of the comparator CP1 goes up to the level L to turn off the TR, and the capacitor C2 is charged through a resistance R10 to change the state of the terminal OUT to the level H. When the voltage VIN rises until VIN<VC2<VS1, the terminal OUT changes in state to the level H immediately.

Title: A/d converter
Inventor: KITA MASAHITO
IPC: H03M1/08
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of an A/D converter whose frequency band of an input signal differs and to reduce the chip occupation area of the A/D converter. SOLUTION: A first operational amplifier 31, a second operational amplifier 36 which is connected to it in parallel and can operate at higher speed and a selection means 3 for selectively setting the first operational amplifier 31 and the second operational amplifier 36 to an operation state are installed. When the frequency of an input signal is low, the first operational amplifier 31 is selectively operated and the second operational amplifier 36 is selectively operated when the frequency of the input signal is high by the selection operation of the selection means 3. Thus, power consumption is reduced when the frequency of the input signal is low. Since a part except the first operational amplifier 31 and the second operational amplifier 36 can be shared for realizing the A/D converter different in the frequency band, the chip occupation area of the A/D converter can be reduced.

Filed: 1980-08-13
Abstract: PURPOSE:To quickly and accurately perform convergence adjustments by displaying information on the completion of correction of each adjusting point. CONSTITUTION:Dot patterns projected on a screen 32 represent adjusting points on which the convergence correction is performed. A television camera 30 detects convergence lag and, by its detecting signal, convergence amounts are automatically written in the memory of a digital convergence section 24. When corrections of an adjusting point are completed, a coincidence detecting signal is added to a pattern generating section 16 through a completion displaying counter 28 from a convergence coincidence detecting section 31, and the completion of the correction of the adjusting point is displayed on the screen 32. Corrections of each adjusting point are performed by repeating this procedure. Since adjusting points on which corrections are completed become clear, convergence adjustment is performed quickly and accurately.

IPC: F02D45/00
Filed: 1982-06-29
Abstract: PURPOSE:To prevent generation of engine stall by prohibiting feedback control if a specific driving condition is satisfied when the idling revolution number is controlled by feeding back the flow-rate of the intake air which detours around a throttle valve. CONSTITUTION:An idle revolution-speed control valve 26 is interposed into a by-pass passage 24 which is installed so as to detours around a throttle valve 18 in an intake passage, and is controlled, in the idle driving stage by a digital control circuit 54 according to the difference between the engine revolution number which is obtained from the output of a crank angle sensor 44 and the aimed idle revolution number.

Title: Radial-piston motor
Inventor: UBUKATA HARUKI
IPC: F03C1/40
Filed: 1980-08-14
Abstract: PURPOSE: To stable the speed changing operation of a motor for effecting speed control in three stages, by smoothing the action of a plunger for driving a collar for  placing an eccentric drum in a medium speed position.  
     CONSTITUTION: When achangeover value 17 is shifted to a position C, a port B is connected to a pump 18 to supply pressurized oil to a passage 11a. Since a check valve 14 is provided between a piston chamber I and the passage 11a, the pressurized oil flows into a piston chamber H first. Plungers 8B, 8A are pushed out rightward and leftward by the supply of the pressurized oil into the piston chamber H and moved until collars 9A, 9B come into contact with an inside wall. Subsequently, the oil pressure in the piston chamber H rises to open the check valve 14 so that the oil flows into the piston chamber I to move an eccentric piston 6 downward. As a result, the eccentric piston 6 is placed in a medium speed position by the collars 9A, 9B. The wrong action of the plunger 8A, 8B is prevented by the interposition of the check valve 14.
