Abstract: PURPOSE: To enable to control an operating speed or the like smoothly by a single lever operation, by combining each check valve with a variable pressure reducing valve, in the titled circuit for a hydraulic motor for slewing a hydraulic type crane or the like.  
     CONSTITUTION: When tilting the lever 12 in the direction A, if the amount of pushing-in a rod 10 of the first variable pressure reducing valve 8, that is, the angle of tilting the lever 12 in the direction A is reduced, the secondary pressure of the valve 12 is lowered and the pressing forces for the second check valve 42 and the fourth check valve 44 are reduced by the corresponding amounts. According to this, a hydraulic fluid from a main pump 1 is supplied to a motor 3 through the first  check valve 41, the fourth check valve 44 and the second port 22, while a part of  the fluid is returned to a tank 13 through the check valve 41, the check valve 44  and the fourth port 24, so that the pressure of the fluid supplied to the motor 3 is  reduced. Accordingly, by gradually tilting the lever 12 from a neutral position to  the direction A, the rotation of the motor 3 can be controlled smoothly and a rotor  4 can be accelerated.

Title: Temperature controller
Inventor: TSUCHIYA KATSUHISA
IPC: F24H1/10
Filed: 1993-05-28
Abstract: PURPOSE:To provide a temperature controller which prevents the overshooting of a temperature of hot water supply by changing a gain for setting a heating rate and from which a stable set temperature is rapidly obtained even when the overshooting, in which the temperature of hot water supply to a member to be heated exceeds a set temperature, is generated.

Title: Mutual inductance element
Inventor: SUGITA YOSHIHIRO
IPC: H01F19/00
Filed: 1989-05-19
Abstract: PURPOSE:To obtain a mutual inductance element having a stabilized coupling coefficient by interconnecting an inductance part through the intermediary of a magnetic member. CONSTITUTION:Two or more inductance parts 2 and 3 are positioned through the intermediary of a magnetic member 4, and the magnetic member 4 constitutes a part of the route of a magnetic flux which interlinks with the inductance parts 2 and 3. To be more precise, as the inductance parts 2 and 3 are positioned through the magnetic member 4, the case where a mutual inductance element 1 having the same coupling coefficient K shows increases in the thickness of the magnetic member 4 above those as compared with the case where an insulating sheet is used. As a result, the effect of the slight irregularity in thickness inflicted on the coupling coefficient K becomes small which can be neglected practically. Also, as the magnetic member 4 increases in thickness, the distance between the inductance parts 2 and 3 in increased, and a short circuit is hardly generated between electrodes. As a result, the title mutual inductance element, having uniform coupling coefficient between each of the inductance parts, can be mass-produced in a stable manner, and also the mutual inductance element having no short circuit between electrodes can be obtained.
