Title: Image display device
Inventor: UNEMURA TOYOAKI
IPC: G09G1/20
Filed: 1994-07-06
Abstract: PURPOSE:To highly precisely display a picture on a display element by storing data obtained by time-sequentially sample-holding RGB video signal at every horizontal synchronous period through the use of reference/four phase clocks, sequentially reading them and controlling PWM. CONSTITUTION:A four phase clock generation part 55 divides the frequency of CLK generated by a horizontal synchronizing signal H in a reference clock (CLK) generation part 51 into two, and it outputs CLK 0 to 3 whose phases are 0, 90, 180 and 270 degrees. A modulation control part 57 time-sequentially sample-holds a digital video signals 50RGB by using CLK 0 to 3 and a pulse which a pulse generation part 56 generates from a vertical synchronizing signal V, a signal H and CLK 0. The control part 57 stores data which are sample-held at every horizontal synchronous period, reads them and controls the start/end of the selection of PMW and CLK 0 to 3 from high-order/low-order bits of data. Thus, the display element 47 can display the highly precise image for personal computer without raising a clock frequency.

Title: Power source converting circuit
Inventor: DOUKAN TAKAKUNI
IPC: H03F3/343
Filed: 1988-06-24
Abstract: PURPOSE:To reduce the power consumption required for power conversion and the occupied area by connecting a constant current source consisting of a current mirror circuit to an internal circuit like an LSI in series and applying an external supply voltage to this series circuit and providing a clamping circuit in parallel with this internal circuit. CONSTITUTION:An internal circuit 3 and a constant current source 4 are connected in series between the earth and an external power source which applies VEE (-5.2V). A clamping circuit 6 is connected in parallel with the internal circuit 3. The constant current source 4 consists of a current mirror circuit 51 and a current source 50 of the current mirror circuit. The clamping circuit 6 clamps a VSS terminal at -3.0V. The variation to reduce a voltage VSS of the internal power source is controlled by the constant current source 4 and the variation to increase VSS is clamped by the clamping circuit 6 to obtain a fixed internal voltage. Since the constant current source gives a fixed current to the internal circuit and the clamping circuit, the fixed voltage VSS is obtained independently of the current flowing to the internal circuit. The current mirror circuit controls a large output current with a small input current to reduce the power consumption required for power conversion.

Abstract: PURPOSE: To improve productivity by shifting parts to a parts to a part supply plate to prepare for incorporating parts in a next furnished workpiece after parts are scrapped in a predetermined scrap place by an assembling robot when the parts are defectively incorporated at each assembling station.  
     CONSTITUTION: A pin 10e abutting against a pivotal member 10c and depressed by the lift of a head 10b is inserted in the head 10b. When a sensor cooperating with the pin 10e in the head 10b detects defective fitting a clamp 10 is lifted to lift a clutch outer A from a power unit case W.

Title: Knocking detector
Inventor: IIJIMA TAMOTSU
IPC: F02P5/153
Filed: 1980-11-05
Abstract: PURPOSE: To detect a knocking without extraneous influences such as an engine's chaterring by detecting an ionic current.  
     CONSTITUTION: An ignition plug 2 and an ion probe 3 are disposed oppositely on a line passing through a center of a combustion chamber. For detecting a ionic condition, an ionic current level is inputted to a knocking distinguishing circuit. In the absence of a knocking, the ionic current shows a peak of a relatively moderate curved line in the region of the maximum burning pressure. At an occurance of the knocking, because of a momentary rise of the ionic current, the ion probe 3 exhibits a stiff peak of the current. A comparison of an output of the ion probe 3 with a preset level may detect a knocking, thereby having no extraneous influence on the detection.
