Title: Pattern generating device
Inventor: UEDA GENZO
IPC: G01R31/28
Filed: 1985-09-03
Abstract: PURPOSE:To make generation of test waveform patterns easy by making update period of a clock generating circuit to each address counter progressively small. CONSTITUTION:If becomes possible to designate rise time and fall time of pattern data on a memory only by information of time by storing pattern data making access period accessing (n) address of a pattern data memory 12. Consequently, it becomes not necessary to deal with data and timing separately. Furthermore, as update period of a clock generating circuit is made progressively small as 18a, 18b, 18c, pattern data of relatively long period can be stored in the state of small storing capacity of the memory 12 by designating combining pattern data of different period of generation. Accordingly, generation of multifarious waveform patterns of relatively long period is made easy without enlarging memory capacity.

Title: Distorted picture preparing and processing system
Inventor: MONZEN HIROKUNI
IPC: G06T1/00
Filed: 1989-07-27
Abstract: PURPOSE:To prepare a naturally distorted picture only with the processing of data by executing position conversion by using a coordinate transformation processing part, smoothing processing part and density transformation processing part, smoothing density between picture elements and afterwards, executing the conversion of density. CONSTITUTION:A coordinate transformation processing part 1 inputs picture data 4 and a shape definition parameter 5 and calculates the coordinates of a position corresponding to each picture element shown by the picture data 4. A smoothing processing part 2 smoothes the density between the picture elements in a picture to be converted according to the correspondence of the position coordinates and a density conversion processing part 3 converts the smoothed density between the picture elements. Then, picture data 6 observing the picture shown by the picture data 4 are generated through a wave glass expressed by the shape definition parameter 5.

Title: Transmission system of inter-terminal control signal
Inventor: YAZAWA SHIGEHIKO
IPC: H04L12/52
Filed: 1983-10-18
Abstract: PURPOSE:To transmit assuredly information without reducing the transmission capacity of a data signal by compensating an inter-station control signal with an inter-terminal control signal which is transmitted by a frame preceding or following the inter-station control signal by a prescribed number of frames and at the juncture with a digital exchange. CONSTITUTION:An inter-station control signal OS transmitted by a bit b8 of a frame F(m) of each of channels CHi (i=1-24) is compensated by an inter-terminal control signal TS' transmitted by the bit b8 of a frame F(m-1) preceding the frame F(m) by a frame and held at a buffer Bi for inter-terminal holding. The signal OS is transmitted to a digital exchange via a data speed converting circuit DVTi. Therefore if an inter-terminal control signal TS has a level change in the F(m), the effect of the signal OS is deleted for each section of a digital junction line DPV just by delaying the changing time point of the level of the signal TS up to the next frame F(m+1).

Title: Sample and hold circuit
Inventor: SUGIBASHI FUJIHIKO
IPC: H03F3/45
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a sample and hold circuit insusceptible to the parasitic capacity. SOLUTION: A hold capacity CH1 is charged/discharged at a sampling voltage in a sample state and disconnected from the input voltage in a hold state. An MOSFET 54 connected with the hold capacitor CH1 is then operated by feeding a current thereto thus producing a voltage corresponding to the hold voltage. When a current of substantially identical magnitude in the sample state and hold state is made to flow the MOSFET 5, voltage fluctuation at the terminal of the MOSFET 54 is suppressed at the time of transition from the sample state to the hold state and thereby, the effect of the parasitic capacitor on the hold voltage can be suppressed. When the potentials at the source terminal and the drain terminal of the MOSFET 54 are substantially equalized between the sample state and hold state, the effect of the parasitic capacity on the hold voltage can be suppressed furthermore.

Filed: 1993-07-14
Abstract: PURPOSE:To enable the high-speed processing of image data compression by removing an adder and an incrementer from a DPCM circuit and providing an AND gate, exclusive OR gate and carry look ahead circuit. CONSTITUTION:An output W, for which the bits of an output U from an exclusive OR gate 13 and an output V from an exclusive OR gate 14 are inverted by an inverter 15, is inputted to a selector 6. When the code bit of the output U is '0' and predictive error is '0' or positive, the output U is selected and when the code bit is '1' and the predictive error is negative, the output W is selected. Therefore, the selector 6 passes the absolute value of the predictive error through level detection 3 and outputs the conventionally similar category from a terminal 103. On the other hand, a selector 7 selects either an output (u) or an output (w) similarly, passes an additional bit through a shifter 8, conventionally similarly shifts the additional bit to the side of the most significant bit and outputs it to a terminal 104. Thus, the predictive error can be decomposed into the category and the additional bit, and code inversion processing can be performed simultaneously with predictive error arithmetic.
