Title: Air-fuel ratio controller for engine
Inventor: KONO YASUSHI
IPC: F02D41/14
Filed: 1987-09-25
Abstract: PURPOSE:To prevent misfire from occurring by changing the preset roughness allowable value to be smaller at the time of such driving that an air-fuel ratio will turn to the more lean side than a lean upper limit air-fuel ratio where the air-fuel ratio is preset. CONSTITUTION:At the time of driving an engine 1, an injector 8 is controlled by an air-fuel ratio control device 102 according to a driving state detected by a driving state detecting device 101 from an engine speed signal and each output signal of an air flow sensor 5 and an idle switch 9 at a control unit 15, making it perform air-fuel control. And, roughness showing the combustion instability of the engine 1 is detected by a roughness detecting device 103, and an air-fuel ratio is controlled to the lean side so as to cause the detected roughness to become less than the specified allowable value. At this time, when the air-fuel ratio to be controlled has turned further to the lean side than a lean upper limit air-fuel ratio, the allowable value is made smaller by a roughness allowable value changing device 104.

Title: Optical modulator
Inventor: NUMAJIRI HIROO
IPC: G02F1/313
Filed: 1988-09-30
Abstract: PURPOSE:To increase modulating speed and to use light wavelength over a wide range by split incident light for many optical waveguides by a variable waveguide type optical deflecting element and varying the propagation constants of the waveguides, individually and electrically. CONSTITUTION:The variable phase waveguide type optical deflecting element 4 is used as the deflecting element of the optical modulator. The variable phase waveguide type optical deflecting element 4 splits the incident light for the waveguides, so when the propagation constants of the waveguides are varied individually and electrically, projection light beams passed through the respective waveguides shift the phase. The light, therefore, has a specific angle to the optical axis l and goes to parallel light through a cylindrical lens 6 and is converted on a different optical path P2 through a lens 6 and not transmitted through an optical fiber 7. Thus, the propagation constants of the waveguides of the variable phase waveguide type deflecting element 4 are varied electrically, individually, and repeatedly, so the light can be modulated. Consequently, the modulating speed is made fast, and wide-range light wavelength can be used.

Abstract: PURPOSE:To permit the easy adjustment of a clearance size and to obtain a good weld zone by applying thermal deformation to a strip and moving a strip supply table to adjust the tension of the strip thereby adjusting the clearance between the end edges of the adjacent strips. CONSTITUTION:A signal is fed from an automatic clearance detector 4 to a central control panel 16 which in turn emits an operation command to a driving machine 13 of the strip supply table 5 and the heating element of a heater D when the size of the clearance for welding between the end edges of the adjacent strips 1 approaches the limit of a permissible value.The table 5 is moved rightward by the machine 13 according to the operation command to increase the left side tension of the strip 1 and the calorific value is controlled by decreasing the current of the heating element in the heater D successively from the left toward the right when the clearance size increased. The strip 1 is curved toward the right and the clearance is narrowed. The clearance size is thus maintained always within the permissible value, at which size the winding of the strip 1 is executed. The end edges thereof are at the same time pressed and restrained by rolling down rolls 3 and are welded by an automatic welding machine 14.

Title: Uninterruptible power supply
Inventor: OSHIMA HIROSHI
IPC: H02H7/12
Filed: 1989-09-22
Abstract: PURPOSE:To prevent malfunction by a method wherein a power source is switched into a commercial power source when the overcurrent of the output of an inverter is detected by a first detecting means while a load current is detected by a second detecting means on the side of a load to judge whether trouble is in the title device or on the side of the load. CONSTITUTION:When the output of an inverter 3 is increased by some reason and a first level detector 11 is operated through a current transformer 10, an output overcurrent signal OC1 is outputted. The signal OC1 drives a switching controller 15 to switch a thyristor 6 into another thyristor 7 whereby inverter power supply 3 is switched into commercial power supply 1. A level is detected by a detector 13 through a current transformer 12 on the input side of a load a to input a signal OC2 into an overcurrent main factor discriminating circuit 16. The circuit 16 dicides whether the cause of the overcurrent is in the inverter device 3 or on the side of the load 8 by the input signals OC1, OC2. When the cause of the overcurrent ia decided that it is in the inverter device 3, the commercial power supply 1 is continued while it is returned to the inverter power supply 3 when the overcurrent is released after it is dicided that the cause of the overcurrent is on the side of the load 8. According to this method, malfunction, due to the faulty cooperation of two sets of overcurrent detectors, may be prevented.
