Title: Solenoid valve controller
Inventor: WATANABE NOBUYA
IPC: F16K31/06
Filed: 1983-04-30
Abstract: PURPOSE:To secure a stable control characteristic all the time without entailing any excessive power consumption, by making a solenoid valve operate on such voltage as higher than the rated voltage at a suchlike operation range that rise time in the solenoid valve relatively comes long. CONSTITUTION:The ratio of T1 to T2 (the ratio of valve opening time to closing time) in a control signal to be added to a switch driving input terminal 9 grows large, and when a mean valve of the signal is larger than the setting voltage, no output is generated from a voltage comparator 11 and a relay switch 12 is thus opened. Therefore, a transistor switch Tr3 is in a state of being turned off, and rated power voltage by a first power source 7 is impressed on a solenoid valve's driving coil 1. Next, the valve opening time comes little as well as the ratio of T1 to T2 comes little, and when the output is generated out of the voltage comparator 11, the relay switch 12 is turned on whereby the transistor switch Tr3 is also turned on, cuasing a power circuit at the side of a second power source 6 to get operating, and such voltage as higher than the rated voltage is impressed on the driving coil 1 so that the soelnoid valve is opened in a good respective manner.

Title: Fuel cut control device for internal combustion engine
Inventor: KAMIOKA RYUICHIRO
IPC: F02D41/00
Filed: 1986-04-05
Abstract: PURPOSE:To continually perform an optimum synchronous increase so as to prevent an engine stall, by changing a decision value of engine speed change in which fuel is increased in accordance with the time of a fuel cut when supply of the fuel is restarted. CONSTITUTION:In a control circuit 10, fuel is cut thereafter a throttle valve 21, detected by a throttle switch 22, is placed in the fully-closed position, further when an engine speed, detected by a crank angle sensor 6, decreases to a predetermined speed lower than the fuel injection-cut engine speed, supply of the fuel is restarted. Here the control circuit, which small decrease a decision value of engine speed change in a predetermined time after restarting of the fuel supply when the fuel is cut for a long time, performs a synchronous increase in the earlier timing. While the control circuit, which large increases the decision value of the engine speed change in the predetermined time after the restarting of the fuel supply when the fuel is cut for a short time, performs the synchronous increase delaying its start timing. In this way, air-fuel ratio can be prevented from being placed in overlean and overrich conditions.

Abstract: PURPOSE:To provide a hot rolled stainless steel sheet where the scale of a uniform thickness is easily generated and no surface scale flaw is generated by forming and connecting the lump-shaped scales at high density in the ferritic stainless steel. CONSTITUTION:The surface roughness is set to >=20mum Rmax by grinding thc slab surface with a grinding wheel or the shot-blast, or by other method before the slab made of ferritic stainless steel is inserted in a slab heating furnace to perform the hot rolling. As a result, the uniform and thick scale is easily formed while the slab is heated, and the hot rolling is performed thereafter. When the lump-shaped scale 3 is formed on the surface of thc slab 1, thc roughness is remarkable, and a number of scale flaws are generated. When the double scale where the outer layer is made of Fe oxide 4, and the inner layer is made of Fe or Cr oxide 5 covers the surface to form the uniform and thick scale 6 with small roughness, few scale flaws are found after the hot rolling. The temperature to form the uniform and thick scale is reduced, and the property of the stainless steel is improved through the grain refining of the crystal, etc.
