IPC: G02F1/37
Filed: 1988-06-24
Abstract: PURPOSE:To improve switching characteristic by forming a proton injection area having a width which is narrower than the space between two optical wave guides and having at least a depth which is nearly as same as that of the optical wave guide along the optical wave guides between them. CONSTITUTION:An AlGaAs buffer layer 101 and an AlGaAs clad layer 102 are grown on a GaAs substrate 100. Between the two optical waveguides 110a and 110b on an incident side formed just under the edge of an Au strip 301 for impressing stress, the area (H<+> proton injection area) 109 including the center of no light emission and recombination, having the width which is much narrower than the space between the optical wave guides and having the depth which reaches the AlGaAs clad layer 102, is formed along a light propagation direction in the almost middle of the optical wave guides 110a and 110b. Therefore, free carrier generated in one optical waveguide 110a does not diffuse to the other optical waveguide 110b. Thus, the mismatching quantity of phase larger than in the case that the H<+> injection area is not formed can be obtained and the switching characteristic can be improved.

Title: Brake toggle joint
Inventor: KITA YASUO
IPC: B60T13/567
Filed: 1982-09-09
Abstract: PURPOSE:To increase the space efficiency, by enhancing the rigidity of a diaphragm rotating section only at a part of the external configuration of a power piston having a non-circular shape in cross section where the curvature diameter is increased, and restricting the relative rotation of the power piston and a shell. CONSTITUTION:The shell 1 and the power piston 10 have non-circular shapes in cross section, that is, they have parts having increased curvature diameters and decreased curvature diameters. In such cross sections, as the rotating part 12a of the diaphragm 12, that is, the part having a small curvature diameter has a great change in the perimeter resulting from the movement, it is required that it is expanded circumferentially, while in the case of the rotating part 12b having a large curvature diameter, it is little required that it is expanded circumferentially. Thus, by increasing the rigidity of the rotating part 12b more than that of the rotating part 12a, the guiding of the power piston 10 for the shell 1 becomes more positive, and the relative rotation of them can be prevented.

Title: Control device for internal combustion engine
Inventor: FUKUI WATARU
IPC: F02D45/00
Filed: 1992-06-17
Abstract: PURPOSE:To make backup control possible even if one of signal systems fails, by generating cylinder discrimination signals, which are different from each other, synchronizing with the engine rotation, and by controlling the engine on the basis of the respective cylinder discrimination signals. CONSTITUTION:This device is provided with cylinder discrimination signal generating means 21 and 22 for generating cylinder discrimination signals C1 and C2, and a control means 3A. The plural pulses composing the respective cylinder discrimination signals C1 and C2 contain the pulse having the first pulse width corresponding to a reference position, and the pulse having the second pulse width which is narrower than the first pulse width and is unrelated to the reference position. Then, on the control means 3A, a reference position signal T' is generated on the basis of the logical sum of the respective cylinder discrimination signals C1 and C2 composed of plural pulses corresponding to the respective cylinders, and the engine is controlled on the basis of the respective cylinder discrimination signals C1 and C2 and the reference position signal T'. Thus, when one of the cylinder discrimination signals C1 and C2 fails, the engine can be controlled on the basis of only the other cylinder discrimination signal.

Inventor: GOTO TAKAO
IPC: A61B5/055
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent an eddy current from flowing through a magnetic shunt plate and residual magnetization from being generated without interposing a shield coil between a gradient coil and a magnetic shunt plate. SOLUTION: In this equipment, a gradient current Iy for imaging is allowed to flow through an inner/upper side Y-axis gradient coil 1Yti and an inner/lower side Y-axis gradient coil 1Ybi to form a comparatively small photographable area suited to a comparatively small concerning site. On the other side, the current Iy is also allowed to flow through a medium/upper side Y-axis gradient coil 1Ytm and a medium/lower side Y-axis gradient coil 1Ybm but the direction of the current is opposite to that at the coil 1Yti and the coil 1Ybi. Thus, the generation of the eddy current and residual magnetization is suppressed to improve a picture.

IPC: H03K5/13
Filed: 1994-07-11
Abstract: PURPOSE:To prevent bus fight between input/output buffers by delaying timing for an output gate to be enabled by delaying an output control signal. CONSTITUTION:An output control signal 13 for an output gate 15 is supplied through a delay means 17. The output control signal 13 is delayed by a variable delay circuit 30 of the delay means 17. The timing for the output gate 15 to turn to the enable state is delayed by delaying the output control signal 13.

Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To transfer a sanitary flushing device freely as the contents of stored set states are left as they are held in the sanitary flushing device, in which the set state of sanitary functions such as the supply of flushing water, the blowoff of hot air, etc., can be stored. SOLUTION: An electronic controller 100 for the sanitary flushing device has a back-up RAM 107, in which data are stored even under a nonconductive state. When 'a high temperature' is selected in a discharged-water temperature set button 13g installed to an operating section 13A, the current state of a tact switch is decided, the fact that a temperature is changed over to 'the high temperature' is stored in the back-up RAM 107 of a sanitary flushing device body under either state of 'off', 'a low temperature' or 'an intermediate temperature', and the temperature of discharged water is set under the state of the high temperature.  When a power supply is turned off and the sanitary flushing device is transferred and the power supply is turned on again in a transfer destination, data stored in the back-up RAM 107 are read, and the temperature of discharged water is set under the state of the high temperature on the basis of the data.
