Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in picture quality when encoding is performed by detecting moving vectors between frames of image data. SOLUTION: A simple motion detecting circuit 3 detects the motion quantities (simple moving vector) between image data (current field image) inputted from outside an encoder 1 and image data (retrieved field image) inputted from a frame memory 2 and outputs them to a decision circuit 4. The decision circuit 4 determines the reduction rate of the image according to horizontal and vertical motion quantities inputted from the simple motion detecting circuit 3 and outputs information on it (image size parameter) to an image size converting circuit 5. The image size converting circuit 5 reduces the image of the image data inputted from the frame memory 2 according to the reduction parameters inputted from the decision circuit 4 and outputs the image to an encoding circuit 6. The encoding circuit 6 encodes the image data inputted from the image size converting circuit 5.

Title: Series/parallel converter
Inventor: SUCHIIBUN CHIYAARUZU KAARUTON
IPC: H03M9/00
Filed: 1986-10-15
Abstract: A serial bit stream (10) and a clock signal (14) at a frequency equal to the bit rate divided by an integer n are passed in opposite directions via respective delay lines (31-37, 41-47) to respectively the data (D) and clock inputs (C) of n flip-flops (21-28), which thereby each latch a respective one of n bits of the bit stream during n/2 bit periods. During the next n/2 bit periods the outputs (Q) of the flip-flops (21-28) are stable, and the n bits are latched in a parallel data latch (12). The delay lines comprise transmission lines terminated with their effective characteristic impedances (38, 48). The converter is particularly useful for bit rates greater than 1Gb/s.

IPC: G02F1/1337
Filed: 1992-09-11
Abstract: PURPOSE:To enable the execution of feedback control of an adequate gap value with every substrate so that an always stable rubbing treatment can be made. CONSTITUTION:The position in the direction perpendicular to the surface of the substrate is measured by a measuring means 5 prior to the execution of the rubbing treatment and this value is converted to the quantity of electricity, which is then outputted to a central processing unit (CPU) 2. This CPU 2 once stores the measured value of the substrate surface into a random access memory 6. The gap value between the previously measured substrate and a rubbing roller is stored into a read only memory 3. The displacement quantity of a stage to be lifted is calculated in accordance with these values. The stage is lifted by a lifting driving mechanism 9 by as much as the height corresponding to this displacement quantity. Further, the substrate is brought near to the rubbing roller by driving a horizontal moving mechanism 8 for a stage base. The rubbing roller rotationally driven by a driving mechanism 7 for rotating the roller rubs the substrate by maintaining an adequate rubbing pressure.

Abstract: PURPOSE:To obtain a sheet type flow rate control valve which can obtain a necessary control flow rate without increasing the valve dimension and deteriorating the responsiveness of the valve by installing a rod having a flange part at the top edge of the outlet side edge part of a main valve. CONSTITUTION:A rod 10 is installed onto the edge part on the outlet 1B side of a main valve 2, and at the top edge part, a flange part 10D having the larger diameter than that of a small diameter part 10C is installed. A fluid power in the valve closing direction acts onto the main valve 2 by the fluid which passes through a metering orifice 2A when the valve is opened. At the same time, in the flange part 10D, a fluid power in the valve opening direction acts onto the main valve 2 by the fluid which flows out from between the inner walls of the flange part 10D and a valve case 1. Since the influence of the fluid power which acts onto the main valve 2 is eliminated, a necessary flow quantity can be obtained without increasing the valve dimension and deteriorating the responsiveness.

Abstract: PURPOSE:To uniformize the composition of an epitaxially grown film on a substrate for epitaxial growth use by a method wherein gas A is made to flow in almost parallel to the surface of the substrate and gas B, which has a nature that the gas B is preferentially taken in a crystal compared to the gas A, is made to flow almost all over the surface of the substrate from a position opposed to the surface of the substrate to perform an epitaxial growth. CONSTITUTION:An epitaxial growth is performed on a substrate 21 using gas obtainable by mixing gas A and gas B having a nature that the gas B is preferentially taken in a crystal compared to the gas A. Here, the gas A is made to flow in almost parallel to the surface of the substrate 21 and the gas B is made to flow almost all over the surface of the substrate 21 from a position opposed to the surface of the substrate 21 to perform the epitaxial growth. Accordingly, as the gas B is made to flow in such a way as to come being diffused uniformly in the flow of the gas A almost parallel to the substrate all over the surface of the substrate from over the substrate 21, a concentration difference in the gas B within the surface of the substrate can be lessened. Thereby, the concentrations of the gases A and B can be held uniformly on the substrate 21 and the composition of an epitaxially grown film which is crystallized on the substrate 21 can be uniformized.
