Abstract: PURPOSE:To enable an instant drive of a bubble bath by a method wherein when the number of times when a filter circuit comes into a circulation reaches a set value, a reverse wash is carried out before an additional heating, so that the reverse wash of the filter circuit has been finished when a successive operation of a bubble generator or an additionally heating device is started. CONSTITUTION:A circulation circuit 1 interposed with a circulation pump is connected to a bath tub B, a bubble generator J1 is mounted on a metal mouth through which a go-passage of the circulation circuit 1 is connected to the bath tub B, and an additionally heating device J2 is connected to a part of the go-passage through a bypass circuit. A filter circuit 2 is connected to this circulation circuit 1. The filter circuit 2 is a closed circuit formed of outlet and inlet sides of the circulation pump connected with each other and inserted with a filter within the closed circuit. The filter circuit 2 works when the bubble generator J1 or the additionally heating device J2 is operated. With the bath device thus constituted, a control is made so that a sum of operation numbers of the devices J1 and J2 is stored in a memory means I, and if the stored sum has reached a set value at a time of input of a water charging signal, a reverse wash is carried out for a prescribed time period, and then, a water charger is operated.

Abstract: PROBLEM TO BE SOLVED: To suppress axial thermal deformation quantity caused by the temp. change in a camshaft by respectively providing regulating means regulating the axial deformation caused by a temp. change at both end positions of a printing region being the boundary part of the shaft and cylindrical part of a camshaft. SOLUTION: Annular grooves 31, 33 are formed at both end positions of a printing region of the shaft 13 in a camshaft 1 and engineering plastic constituting a cylindrical part enters the parts of the annular grooves 31, 33 at a time of injection molding and these parts become annular protruding parts 35, 37. Regulating means 30, 30' regulating the axial deformation caused by the temp. change at both end positions of the printing region are respectively constituted by the fitting structure of the annular groove 31, the annular protruding part 35, the annular groove 33 and the annular protruding part 37.  For example, when the shaft 13 and the cylindrical part 15 are ready to thermally expand axially by a temp. rise, by this fitting structure, the linear expansion of the cylindrical part 15 large in the coefficient of thermal expansion is regulated by the shaft 13 low in the coefficient of thermal expansion.

Title: Method for underground storage of gas
Inventor: MEEMETSUTO REIJIN TETSUKU
IPC: B65G5/00
Filed: 1991-07-24
Abstract: PURPOSE: To prevent the mixture of a storing gas and a substituting gas from occurring by injecting specified amounts of the storing gas and the substituting gas in a cavern, and generating a gas pressure which is larger than a minimum pressure by which the gases are carried from the cavern by a specified flow rate. CONSTITUTION: A salt cavern 10 is constituted by dividing into an upper chamber 24 and a lower chamber 26 by a flexible film 22 which is seal-provided on the cavern wall 28 along the peripheral section of the salt cavern. The amount of a substituting gas (remaining gas having a pressure required to derive a storing gas) which exists in the lower chamber 26 is a specified fixed amount, but the volume changes depending on the pressure, the flexible film 22 and the pressure of the stored gas in the upper chamber 24 on the top. When a sufficient stored gas is injected in the cavern 10, and the pressure rises, the flexible film 22 descends downward. When the storing gas is derived from the cavern 10, and the pressure is lowered, the flexible film 22 rises and returns to the original location.  For the filling of the gases into the cavern 10, a simultaneous injection of the substituting gas and the storing gas is preferable, and a pressure difference in the vertical direction of the flexible film 22 is kept small, preferably at zero.

Title: Motor drive circuit
Inventor: YOSHIHARA TAKAO
IPC: H02P8/00
Filed: 1986-08-08
Abstract: PURPOSE:To prevent a large current from flowing to a motor drive circuit thereby to prevent a power source from being damaged by connecting a reset signal at the time of turning ON the power source to the reset terminal of a monostable multivibrator. CONSTITUTION:A monostable multivibrator 1 is reset at the time of turning ON a power source by a resetter 4 connected to the reset terminal R of the multivibrator 1. Accordingly, since a signal is not output from the output terminal Q of the multivibrator 1 at the time of turning ON the power source, a transistor Tr1 is nonconductive. Thus, even if a transistor Tr2 is conducted at the time of turning ON the power source, only a rated current flows to the coil 2 of the motor. Therefore no overcurrent flows to the coil 2 of the motor.

Filed: 1991-07-25
Abstract: PURPOSE:To suppress the generation of the electromagnetic interference noise of an output circuit when a power supply voltage is high and to quicken the rise and the fall of the circuit when the power supply voltage is dropped.
