Title: Flow control device for valve
Inventor: ASANO HIROSHI
IPC: F15B13/044
Filed: 1989-08-11
Abstract: PURPOSE:To prevent the hunting and response delay of a valve and stabilize the flow control by adding devices measuring the fluid pressure at the inlet and outlet of the valve, and multiplying a command signal by the inverse number of the square root of the difference between the inlet pressure and the outlet pressure. CONSTITUTION:Pressure gauges 5-7 measuring the fluid pressure are provided at the inlet and the outlet of a valve 1. An arithmetic device 9 determines the difference DELTAP between inlet pressures 6 and 7 and the outlet pressure 5 and calculates the inverse number of its square root. It multiplies a deviation signal between the command flow and the measured flow or a command signal PID-controlled with the deviation signal by the inverse number. The stable flow control can be continued without causing the hunting and response delay of the valve 1.

IPC: G06F11/28
Filed: 1984-10-05
Abstract: PURPOSE:To make debugging having complicated memory access sequence reproducing the state similar to an actual environment by detecting a sequence made up of plural memory requests, and detecting debug interruption. CONSTITUTION:A comparing section 6 sets the kind of actual memory request instructions and information of access address as one input, and sets the kind of memory request instructions read out from a debug information storing section 4 according to an address pointer 5 and the information of access address as another input and compares them.

Title: Correcting system of set duty of speed controller for car
Inventor: MASUDA JIRO
IPC: B60K31/06
Filed: 1985-09-21
Abstract: PURPOSE:To reduce the stationary error in constant speed traveling due to the set deviation by correcting the set duty by the correction value of the set duty which is obtained from the speed difference between the traveling car speed and the set car speed, when the difference exceeds a prescribed nonsensitive band width for a certain time or more. CONSTITUTION:In the SD initialization, the set duty SD is read out from a standard control line when the set car speed VM is memorized. Then, the difference VM-Vn between the traveling car speed VN and the set car speed VM is obtained, and the output duty DU is changed according to the speed difference. In this step, Vi=(Vn-Vn-1)Tc/DELTAt+Vn, DU=(100/VB)(VM-Vi)+Sd, in which Vi is the value obtained by advance-angle-compensating the traveling car speed Vn according to the advance angle time Tc. In the forestage, the set duty itself is corrected by the equation SD (100/K)(VM-Vn)+SD. In this case, the protection time for a certain time T is set so that SD correction is carried out so far as the time when the nonsensitive band width in which SD is not corrected is exceeded is longer than the ordinary car speed variation.
Patent JP-H0495987-A (JP)
Title: Temperature detecting and correcting method
Inventor: YOSHINO HIROBUMI
IPC: G05D23/24
Filed: 1990-08-07
Abstract: PURPOSE:To prevent a user from being kept waiting without executing copying in a correction mode by stopping succeeding correction in the case that a measured correction quantity is converged to a specified quantity or under. CONSTITUTION:A correction term DELTAt which is a point is obtained by the difference of the detected temperature (ts) detected at the contact position and the non-contact position of a thermistor with the roller. When DELTAt is within the range of a fixed value, it is compared with the previous DELTAt. In the case that the difference is equal to or under the fixed value, for example, 1 deg.C, DELTAt is not updated by judging that the inner part of a fixing unit becomes a thermal equilibrium state, and the measurement of DELTAt is not executed next. In the case that the difference exceeds the fixed value, DELTAt is updated to DELTAt which is newly measured. Thus, the user is prevented from being kept waiting without executing the copying in the correction mode.

Title: Data transmitting method
Inventor: MATSUMURA TOMOYOSHI
IPC: H04L29/10
Filed: 1982-11-30
Abstract: PURPOSE:To perform effective data transmission by operating a serial input/ output control part in interruption operation mode during data reception or operating in DMA mode during data transmission in a binary synchronous communication system. CONSTITUTION:The binary synchronous communication system is unable to estimate data length during reception, so an interruption system is employed. When data is received from a communication circuit, the serial input/output control part 30 generates an interruption signal INT. Consequently, a CPU10 reads received data RXDA to process plural received data from a multistage receiving buffer 35. A DMA system is utilized for transmission. Transmit data TXDA is transmitted according to a DMAC40 without the intervention of the CPU10. Consequently, there is no limitation of interruption delay during transmission, and effective data transmission is performed by the multistage receiving buffer during reception.

Abstract: PURPOSE:To obtain a foamed sheet showing excellence in design and durability as an ornamental sheet by a method wherein a plastisol prepared by dispersing methacrylate resin in a plasticizer for vinyl chloride resin is applied partially on a foamable soft vinyl chloride resin layer and then heated. CONSTITUTION:After a foamable PVC layer 2 is formed on a substrate 1, a plastisol prepared by dispersing methacrylate resin in a plasticizer for PVC neither dissolving nor swelling this resin is applied on a part of said layer in which a projection is desired to be formed. The plasticizer in the plastisol migrates into the foamable PVC layer 2 in the part 4 coated with the plastisol, and as the result, this part 4 obtains a higher foaming ratio faster than the other part. Consequently, the projection can be formed therein, and further a methacrylate resin protection layer 4' strengthened by the separation of the plasticizer from the resin in the plastisol is formed on the surface of the projection.
