Filed: 1986-01-14
Abstract: PURPOSE:To improve stability and responsiveness of the device in the caption by providing a compression signal conversion means and a integrating means between a computing means and a valve-opening signal generating means. CONSTITUTION:A compression signal conversion means 11 and an integrating means 12 are provided between a computing means 18 and a valve-opening signal generating means 13, said compression signal conversion means 11 transmitting a compression signal W which presents larger compression ratio as the difference signal V becomes larger while smaller compression ratio as the difference signal V becomes smaller, and said integrating means 12 time- integrating said difference signal V. Due to the above construction, the responsiveness of the whole control system can be improved by said compression signal conversion means 11 to realize a closed loop controlling system with less steady-state deviation, while the steady-state deviation can be made better by the provision of said integrating means 12 at the cost of worsening of the responsiveness. Thus, valve-opening signal with satisfactory stability and responsiveness can be obtained from said valve-opening signal generating means 13.

Title: Freezing device
Inventor: SUGIYAMA KUNIO
IPC: F25B1/00
Filed: 1989-01-12
Abstract: PURPOSE:To improve return of liquid from a condenser to a receiver by a method wherein a bypass pipe is connected through a solenoid valve, performing an opening motion during operation, to a line between the upper part of the receiver and the low pressure pipe on the outlet side of a vaporizer, and a pressure in the receiver is reduced to a value lower than that in the condenser. CONSTITUTION:In the station of a motion (operation), with a solenoid valve 12 brought into an opening state, a part of high pressure gas in a receiver 3 flows through bypass pipes 11a and 11b to a low pressure pipe 9. Though a pressure in the receiver 3 is adjusted to approximately the same value as that in a condenser 2 by means of a pressure uniformizing pipe 10, through the flow of high pressure gas to the low pressure pipe 9, the pressure in the receiver is reduced to a value lower than that in the condenser 2. Namely, since, in addition to a fact that a liquid refrigerant is returned to the receiver 3 under gravity, it is positively returned through the action of a difference between pressures, return of a liquid refrigerant is improved. Further, even when a transient state in which a pressure in the receiver 3 is increased to a value higher than that in the condenser 2 is created due to some cause, it can be immediately restored to a normal pressure state through the solenoid valve 12 and the bypass pipes 11a and 11b.

Title: Method for information write
Inventor: SHIBATA ISAMU
IPC: H04N1/053
Filed: 1981-01-20
Abstract: PURPOSE:To determine correctly the write position of a photoreceptor without photodetectors, by synchronizing a sweep signal, which drives an acoustic optical modulating element, with a clock signal which outputs information signals successively. CONSTITUTION:A counter 31 counts a clock signal by a reset signal inputted at a constant period, and a sweep signal which has the output frequency increased successively is applied from a voltage-frequency converter 34 to an acoustic optical modulating element 5, and the laser beam is deflected successively to scan a photoreceptor 13. Meanwhile, the clock signal is inputted to a memory 35, and stroed information signals are outputted successively synchronously with the clock signal, and the laser beam is modulated optically by a modulating circuit 14. Thus, since the sweep signal and the clock signal are synchronized with each other on a basis of the reset signal, a picture write position of the photoreceptor 13 is determined correctly.

Title: Method for coding video frame sequence, system and medium usable by computer
Inventor: EDWARD F WESTERMAN
IPC: H04N7/50
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system to discriminate dynamically a size of a picture group (GOP) as a function of a picture change activity in a video frame sequence and to provide a product of a computer program. SOLUTION: In the image statistics with respect to one or plural intra-frame characteristics of a video frame sequence, a preset threshold value (331) is compared to decide whether the statistics is conducted in a current GOP or a new GOP is started. A frame in the video frame sequence is intra-coded and each of succeeding frames of a variable number is subject to 2-way prediction coding (B). Each B frame in succession to an I frame is coded from the I frame by using only forward prediction motion estimation. On the occurrence of prescribed deterioration in a picture, a new GOP is started for the processing. One example of an intra-frame characteristic to be monitored is the number of macro blocks that are intra-coded in each coded B frame. This number is compared with a threshold value and the threshold value may be a part of a total number of macro blocks in a frame.

Title: Platen roll
Inventor: NOMA HIDEYUKI
IPC: B41J11/02
Filed: 1985-01-17
Abstract: PURPOSE:To enable a paper to be moved smoothly, by providing a coating of a specified silicone base releasable material on a synthetic rubber layer. CONSTITUTION:The synthetic rubber layer of a platen roll is coated with a silicone composition in which compounds of formulas 1, 2, 3, 4 and a catalytic amount of platinum or a platinum compound are mixed with each other as plastic silicone resin components in a weight ratio of 1:1-1:30. Since the surface of the platen roll thus obtained has the coated silicone base film having excellent releability and a low coefficient of friction, when the platen roll is used as a flat platen in a word processor or various printers, the paper will not adhere or stick to the platen. Accordingly, the paper is fed extremely smoothly, and adhesion of scum of dust is effectively prevented from occurring, resulting in an advantage of favorable printability on the surface of the paper.
