Title: Flow controller for power steering device
Inventor: TAKEUCHI KATSUYUKI
IPC: B62D5/087
Filed: 1991-05-31
Abstract: PURPOSE:To solve using a simple structure the problem of the discharge of a pump being decreased when the open area of a restricting passage is restricted as the differential pressure between portions in front of and behind a fixed orifice is increased with an increase in the viscosity of a fluid at low temperatures and a control spool is largely displaced, in a revolution sensing type flow controller in which the control spool is displaced by the differential pressure between the portions in front of and behind the fixed orifice caused by an increase in the discharge of the pump so as to perform variable control of the open area of the restricting passage. CONSTITUTION:A control spool 23 is formed from synthetic resin which greatly contracts at low temperatures from a union 21 in which a sliding hole 21c against which the control spool 23 slides is formed, and at low temperatures a clearance formed on the outer periphery of the control spool 23 is enlarged and a fluid located in front of a fixed orifice 31 and acting on the control spool 23 is made to leak from the clearance toward a restricting passage 24a so as to reduce pressure in front of the fixed orifice 31.

Inventor: WATANABE HISAYASU
IPC: F24H1/00
Filed: 1995-04-28
Abstract: PURPOSE: To suppress occurrence of water hammer at the time of starting filling a bathtub with hot water by opening a water flow control valve when a preset minute wait time has elapsed from the time of receiving a time measuring signal of a time measuring part to open a hot water supply control valve. CONSTITUTION: A hot water supply pipe 17 is provided with a bypass passage 28 which bypasses a water flow control valve 26, and at the time of starting filling a bathtub with hot water the water flow control valve 26 is closed before a hot water supply control valve 5 is opened, and after a minute wait time has elapsed from the time of opening the hot water supply control valve 5 and flow through the bypass passage 28 has been stabilized, the water flow control valve 26 is opened. Because the flow rate is increased from a flow rate of zero to a flow rate in the bypass passage 28 and after the stabilization of the flow the water flow control valve 26 is opened to increase the flow rate stepwise, the variation of the flow rate is kept smaller than that when the flow rate is changed straight from a flow rate of zero to a target flow rate, and water pressure variation becomes small.  Water hammer caused by rapid water pressure variation can be suppressed.

Abstract: PURPOSE: To improve a compression efficiency by providing on the crank-shaft side of a piston holder which has a higher coefficient of thermal expansion than that of a piston constituent member to properly adjust and even a clearance between the piston and a cylinder in compressing operation.  
     CONSTITUTION: At a specific insertion location 8a which is at the inner side of an open end of a piston 8 made of an Fe20 or the like in one body with a bottom on the side of a crankshaft, is fixed a disk keeper 17 of a piston wall keeper which is made of carbon steel for example having a higher coefficiency of thermal expansion than that of an FC and has a spherical bearing face 16 at the center.

Abstract: PURPOSE: To perform a predictive control of MLSS concentration exactly with an allowance for growth amount by controlling the amount of sludge inside aeration tank by making a predictive calculation of concentration of mixed liquor suspended solids (MLSS) in aeration tank.  
     CONSTITUTION: Using the actually measured values of entering sewage amount, entering sewage SS concentration, MLSS concentration at the outlet of aeration tank, returned sludge amount, and returned sludge concentration, the amount of grown sludge and the growth rate are obtained from an equation of sludge balance at the inlet and outlet of the aeration tank with an allowance for the residence time. Then, the MLSS concentration at the outlet of the aeration tank is claculated from values obtained by predicting the growth rate on that day on the basis of the growth rates in the past, and then the residence time is calculated by using the predicted value of inflow and the amount of returned sludge in the following scheduled operations. Also, after the calculation of predicted MLSS concentration after the residence time at the outlet of the aeration tank for entering sewage at the present time, it is compared with the set value of MLSS received separately, and if the set value is unsatisfying, recalculation is made by changing returned sludge amount and the returned sludge amount is determined by aiming at the MLSS concentration as a target.

Title: Initializing device of semiconductor integrated circuit
Inventor: KAWAI SATORU
IPC: G06F1/24
Filed: 1982-07-27
Abstract: PURPOSE:To eliminate the complication of the operation for initialization, by initializing a device only when data in a specific area of an RAM does not coincide with initializing pattern data at the time when an initializing pulse inputted. CONSTITUTION:The initializing pulse is given when an electric power is supplied to an LSI, and the initializing operation is performed by an initializing circuit 3 when initializing pattern data does not coincide with data in an area A of an RAM1, and a normal control operation is started after initializing pattern data is written in the area A. Hereafter, when the initializing pulse is inputted by a sudden change of the power source voltage or a noise pulse, read data from the area A and input pattern data are compared with each other. If they do not coincide each other, the initializing operation is performed and data is written; but if they coincide each other, the initializing operation is performed only when it is required. Consequently, since the time set is not performed as long as data is held in the RAM after the device is initialized once, the time set is not performed more than needs.
