Title: Method and device for reducing wear of valve seat in pipe line
Inventor: MIZOGUCHI MITSUJI
IPC: F16K3/22
Filed: 1995-01-23
Abstract: PURPOSE: To improve the wear resistance by operating a driving device so that a stem may be turned at a low speed when a valve disc approaches a valve seat and the flow rate in the pipe line is small while at a high speed when the valve disc is sufficiently away therefrom and the flow rate becomes large to reduce the possibility of rubbing the valve seat by the valve disc when being opened/closed. CONSTITUTION: An eccentric valve A provided with a disc-shaped valve disc is used for controlling the pipe line E, and a stem to turn the valve disc is connected to an output part of a two-stepped driving device B. A control means D consists of a controller 41 and a throttle valve 24, and the supply of the compressed air from a compressor 43 to the two-stepped driving device B is adjusted by the throttle valve 42 through the controller 41 to operate the driving device B both at a high speed and at a low speed. When a disc-shaped valve disc of an eccentric valve A approaches the valve seat and the flow rate of the pipe line E is small, the driving device B turns the stem at a low speed. When the valve disc is sufficiently away from the valve seat and the flow rate becomes large, the stem is turned at a high speed.

Title: Magnetic recording medium
Inventor: NAKAMURA NOBUO
IPC: C08L67/02
Filed: 1982-01-20
Abstract: PURPOSE:To improve the corrosion resistance for a magnetic recording medium, by using a substrate of a polyester film having the density of Na or K less than a specific level at the surface part and then forming a ferromagnetic thin film on said substrate. CONSTITUTION:A substrate film is controlled so that the density of Na or K is set at <=0.03atom% at the surface part of a polyester film to be used to a substrate. Then a thin film of iron, cobalt and nickel or an alloy containing mainly  said elements is formed on the substrate film by a vacuum vapor deposition process, etc. Thus a desired magnetic recording medium is obtained. This recording medium has no rust nor discoloring, etc. due to corrosion although it is left for a long time at a high temperature and high humidity. On the contrary, if Na or K exists in a high density, a local battery is formed to cause the local corrosion. In addition, the water condensation is caused on the surface to elute the impurities. Then the corrosion current increases to spread the corrosion over the entire surface.

Abstract: PURPOSE:To start the operation automatically after power restoration, by setting a power failure/power restoration memory again to restart the execution of an unprocessed job if a power failure is generated during the execution of the job or the start of the job is set during the power failure. CONSTITUTION:When the power failure is recovered, a power failure/power restoration detecting part 3 detects it to input a signal to a clock part 5, and therefore, the power restoration time is inputted to a power failure/power restoration time holding part 6 and is stored. An information processing part 1 reads out information which indicates whether a power failure event holding signal from a power failure event holding part 4 is generated or not; and if it is generated, the information processing part 1 reads the occurrence time of the power failure and the power restoration time from the holding part 6 through a data bus 9. Job scheduling time information set to the clock part 5 is read out, and the occurrence time of the power failure is compared with the execution start time of each job, and jobs are executed before the other unprocessed jobs if they are scheduled during the time from the power failure time to the power restoration time.

Abstract: PURPOSE:To stabilize air-fuel ratio control at boundary area between lean and enrich driving conditions by controlling air-fuel ratio on the basis of intake air pressure or intake air amount with a load below the set level as well as of throttle opening with a load over the set level. CONSTITUTION:In a control circuit 1, a lean correction factor is operated by width of injection pulse and engine speed, and so is an enrich correction factor by throttle opening detected by a throttle opening sensor 6 and engine speed.
