Title: System for compressing and extending video signal
Inventor: KAI YOSHIHIDE
IPC: H04N19/593
Filed: 1989-02-21
Abstract: PURPOSE:To compress a video signal by executing the weighting addition of a signal level in plural referring picture elements, forecasting the signal level of the noticed picture element and subtracting the forecasted level from the true signal level of the noticed picture element. CONSTITUTION:An input video luminance signal Y is converted to a digital signal through an A/D conversion circuit 1Y, given to a frame memory 2Y and stored. The memory 2Y reads the luminance signal of the picture element in a position different from that of the writing picture element parallelly with the writing of the luminance signal Y and gives the read signal to a noticed picture element level forecast circuit 3Y. The circuit 3Y obtains the forecast signal level of the noticed picture element and gives it as a subtraction input to a subtractor circuit 4Y. The luminance signal from the memory 2Y is directly given to the circuit 4Y as an input to be subtracted. A different level between the true signal level of the noticed picture element and the forecast signal level of the noticed picture element is obtained from the circuit 4Y and given to a code quantization circuit 5. For color difference signals I and Q, the different level is samely given to the circuit 5 and an optimum approximation vector number is obtained from the respective different levels. Then, the data are compressed and outputted to a transmission control system.

Title: Video signal processing circuit
Inventor: KAMEMOTO KAZUHIRO
IPC: H04N5/45
Filed: 1991-03-06
Abstract: PURPOSE:To prevent a picture of a sub-pattern from being abnormally lighted or darkened when a main pattern and the sub-pattern are displayed simultaneously on one picture tube by varying a slice level and a gamma correction quantity depending on a level of a luminance signal of the sub-pattern. CONSTITUTION:A luminance signal (Y signal) is fed to a Y signal input terminal 20, a Y signal subject to signal processing is extracted from emitters of transistors(TRs) 12 and fed to a Y signal output terminal 22. The TR 1 is formed to be an emitter follower and the TR 2 forms a constant voltage source. For example, when the Y signal having a high average modulation is supplied to the TRs 1, 2, a diode D1 for gamma correction is conductive at most of the pattern period and the gamma correction effect is produced. Moreover, a capacitor C1 is charged by the on-current of the TR 2, a base voltage of the TR 2 rises and an emitter voltage rises. Thus, a slice voltage gets higher and the picture of the sub-pattern is prevented from abnormally getting brighter.

Abstract: PURPOSE:To perform energy-saving of an electric forklift truck by regeneratively braking the truck when the rotating speed of a motor is high and switching to a plugging brake when the speed decreases. CONSTITUTION:When a reverse switch RS is closed while an electric truck is traveling forward, an armature MA is first switched to reverse polarity, and a field energy is applied through a field resistor R1 to a field MF, thereby forming a field magnetic flux.

Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently set the Reynold's number Re of a measurement part and to prevent a body to be tested and a wind tunnel balance from being applied with an excessive shock due to the change of air current state in the beginning of a wind tunnel test. SOLUTION: According to values representing the Reynold's number set value Re of the measurement part 8, the Mach number set value M of the measurement part, and all temperatures T0a, T0b.K2 of a collection tunnel 6, a total pressure arithmetic circuit 39 derives the target total pressure P01 of the collection tunnel and then the opening degree of a pressure governor valve 5 is controlled.

Filed: 1994-03-11
Abstract: PURPOSE:To form an interpolated image, for which unsharp is inconspicuous, even when the frame rate of ultrasonic image pickup is low by performing interpolating operation while non-linearly weighting an interpolation coefficient so that the inclination can be enlarged near any specified %. CONSTITUTION:A received signal from a probe 2 is processed by an ultrasonic transmission/reception part 2, converted to a digital signal by an A/D converter 3 and stored in any one of image memories 4, 5 and 6 for each image frame. Next, the interpolation coefficient outputted from an interpolation coefficient generation part 14 is multiplied to the data read out of the respective image memories 4, 5 and 6 by multiplying parts 7, 8 and 9. In this case, when a frame scanning rate gets close to 50%, the inclination of interpolation coefficients alphaand beta near 0.5 is enlarged, the time duration near 0.5 is decreased, the ratio of the time to display a source image almost as it is increased, and the unsharp of this image is decreased. Thus, even when the frame rate is low, the unsharp of the image caused by interpolation processing can be made inconspicuous.

Title: Memory unit
Inventor: SUGIMOTO EIJI
IPC: G11C11/412
Filed: 1978-04-06
Abstract: PURPOSE:To obtain a memory circuit which features no malfunction and high performance and can be reduced in area when formed into an IC for the memory unit using IGFET, by performing the charge of the data line with the delay corresponding to the delay time of the address line. CONSTITUTION:Output DP of inverter GC2 features the delay of tD and tE compared with precharge signal P by the rise and fall due to inverter GC1 and GC2. And tD is larger than delay tB of the address line, and the precharge is given in the period of TP-tD. The level of address line AA1 is activated in low-level period TA of signal P and features the delay of tA and tB at rise and fall each. Data line DA is charged in only period Talpha and Talpha2 during which signal P and PD overlap. And tD tB is set, and thus the address signal is 0 in the effective precharge period. Thus, the memory element and the data line are isolated from each other. As a result, the overlap between the precharge signal and the address signal is avoided, thus obtaining an IC-formed memory circuit free from malfunction.

Abstract: PURPOSE:To prevent a shortage of a dielectric breakdown strength and an increase in a leak at a low electric current by a method wherein, before a first-conductivity-type impurity layer is formed, a groove is formed, a distance between the first-conductivity-type impurity layer and a first-conductivity-type buried layer is shortened and the first-conductivity-type impurity layer is brought surely into contact with the first-conductivity-type buried layer. CONSTITUTION:A first-conductivity-type buried layer 12 is formed in the main surface of a semiconductor substrate 11; in addition, a second-conductivity-type epitaxial layer 13 is formed on the semiconductor substrate 11. Then, a groove 18 is formed in the surface of the second-conductivity-type epitaxial layer 13; a firstconductivity type impurity layer 16 is formed inside the secondconductivity-type epitaxial layer 13 from the bottom of the groove 18; after that, an oxide film layer 17 is formed. In this case, when the groove 18 is formed in advance in a region to form the first-conductivity-type impurity layer 16, a distance between the first-conductivity-type buried layer 12 and the first-conductivity-type impurity layer 16 is shortened; when the first conductivity-type impurity layer 16 is formed in this region, the first-conductivity-type impurity layer 16 is brought surely into contact with the first- conductivity-type buried layer 12. Thereby, it is possible to prevent a shortage of a dielectric breakdown strength and an increase in a leak at a low electric current.
