IPC: H02M7/797
Filed: 1989-10-03
Abstract: PURPOSE:To prevent the deterioration of a power factor by deviating the phase of first and second current commands with respect to the phase of an AC voltage respectively by a predetermined amount. CONSTITUTION:The phase of a first current command I is shifted so as to compensate a phase difference between an AC voltage Vm and a component corresponding to the first current command (effective current command) I among the current component constituting an input current while the phase of a second current command (power source compensating current command) I is shifted so as to make a current component corresponding to the AC voltage Vm inputted into a current control loop as an external turbulence zero. According to this method, the deviation of the phase of the input current cf a PWM converter with respect to the AC voltage Vm is compensated whereby the deterioration of a power factor can be prevented.

Title: Manufacture of liquid crystal display panel
Inventor: YOSHIDA NOBORU
IPC: G02F1/1341
Filed: 1986-10-29
Abstract: PURPOSE:To obtain a highly reliable liquid crystal display panel which is free from fluctuation of the dimensions of a sealing agent, by applying the sealing agent to an injecting hole in a state where two transparent substrates in the vicinity of the injecting hole of the panel are pushed toward another by means of a pressing jig, etc., with a fixed pressure and completely sealing the panel after the sealing agent is sucked in the panel by removing the pressure. CONSTITUTION:A panel is pressed with a fixed pressure by means of a panel pressing jig 6 and the panel is depressed before applying an enclosing agent 4 to an injecting hole 4. When the sealing agent 5 is applied to the injecting hole 4 under this condition and the pressure is removed by removing the jig 6 after applying the agent 5, the panel returns to its original state where it is not depressed and the sealing agent 5 is sucked in the panel. The panel pressing conditions (pressure, pressing place, etc.) depend upon the shape of the panel. Therefore, a liquid crystal display panel which is high in airtightness, reliability, and quality and free from fluctuation of shape and dimensions is obtained.

Inventor: ISHIBASHI TATSUO
IPC: G01V8/12
Filed: 1992-09-02
Abstract: PURPOSE:To obtain a liquid sensor for pipeline which does not function erroneously and detects liquid correctly when the liquid begins to flow again into the pipe line after temporary exhaustion of the liquid from the pipeline. CONSTITUTION:The liquid sensor being installed on the way of a pipeline in order to detect liquid therein comprises an inlet pipeline 3, an outlet pipeline, a central pipeline 5 of which both ends communicate with the inlet and outlet pipelines 3 and 6, respectively a prism 7 extending in the axial direction of the central pipe line 5 while opposing thereto, and light emitting elements 8, 9 disposed oppositely to the reflecting faces 7b, 7c of the prism 7.

Filed: 1994-10-24
Abstract: PURPOSE: To simplify a converting circuit for output signal by controlling the feed of a film on the basis of the comparison result of the output signal of a plurality of perforation detecting means with a threshold signal corresponding to each detecting means. CONSTITUTION: A threshold signal for PS1 and a threshold signal for PS2 are switched on the basis of the perforation detection result of sensors PS1 and PS2 inputted through a comparator CP1, and their digital threshold signals are transmitted to a D/A converter, converted into analog voltage therein, and set in the comparator CP1. On the basis of the comparison result of the output signal of a plurality of perforation detecting means with the threshold signal corresponding to each detecting means, the feed of a film is controlled. Thus, the detecting levels of the sensors can be independently set, so that a precise perforation detection can be performed. Further, the comparator can be commonly used to reduce the number of part items.

Title: Portable electronic computer terminal
Inventor: FUNANE TORU
IPC: G06F1/26
Filed: 1990-09-27
Abstract: PURPOSE:To improve the operability of a portable electronic computer terminal by selecting the desired one of battery units based on the detection voltage of plural voltage monitors. CONSTITUTION:When a voltage monitor circuit 12 serving as a detector means detects that the terminal voltage of a battery unit 14 drops to less than a prescribed level, interruption signals is sent to a CPU 2 every two seconds, for instance. The CPU 2 executes a program, e.g., a commodity order receiving program stored in a ROM 3 or a RAM 4 and at the same time displays an application screen to a liquid crystal display LCD 7. Under such conditions, the circuit 12 detects the drop of the terminal voltage of the unit 14 and supplies an interruption signal to the CPU 2. The CPU 2 starts a processing routine in response to the received interruption signal. As a result, the consumption of a battery is warned during the execution of the application program and the processing is carried on as it is without exchanging the unit 14.

Abstract: PROBLEM TO BE SOLVED: To display a biological signal so as to equally scroll the waveform of biological signal at the frame rate of a monitor by displaying the biological signal to be displayed on a display means while shifting it for prescribed quantity when the frame rate of a photographing means is delayed rather than that of the display means. SOLUTION: A CPU 212 monitors the frame rates of a TV camera 107 and a monitor 117 and, when the frame rates are equal, '0' is outputted to a latch 213, but when the frame rate of the monitor 117 is accelerated rather than that of the TV camera 107, 'shift quantity' is outputted. A comparator 215 compares the value of a memory for storing a value corresponding to a display area with the output value of a horizontal counter 214 for control and a digital switch 203 is turned on/off. A buffer memory 114 for waveform is made into a double screen buffer composed of RAM 201 and 202 and the initial value of a read-out horizontal counter 211 is set for picture element clocks corresponding to the 'shift quantity' successively from '0' and read out. Thus, the display waveform is successively moved to left at the frame rate of the monitor 117.
