Title: Hydraulic buffer for rear wheel of vehicle
Inventor: KASHIMA MITSUHIRO
IPC: B60G17/08
Filed: 1981-03-02
Abstract: PURPOSE:To prevent the Willy phenomenon of a vehicle, by providing a relief valve whose relief set pressure is changed in proportion to the pressure of an oil reservoir and by providing another relief valve which is closed at the time of acceleration to heighten the pressure of the oil reservoir and by connecting the relief valves in series with each other in the working oil passage of a hydraulic buffer whose tank is separately placed. CONSTITUTION:When a piston rod 2 performs compressing action, working oil flows from a lower chamber B into an oil chamber C and a comunication chamber D and the rise in the pressure of the chamber D is so slow due to the action of an orifice that a spool 17 is moved toward the communication chamber D. At that time, a relief valve 6 is opened to reduce the oil flow to an oil reservoir J. When a solenoid 33 is energized by the output of an acceleration sensor, an operating shaft 42 is retracted and a valve 40 is caused by the force of a spring 45 to close a passage M. As a result, the pressure of an oil chamber E and the communication chamber D is made higher than that of the oil reservoir J, by the set pressure of the spring 45, to move the spool 17 toward an atmospheric chamber 18 to increase the resistance to the flow to the oil reservoir J. A Willy phenomenon is thus prevented.

Title: Enclosed rotary electric compressor
Inventor: MURAMATSU SHIGERU
IPC: F04C23/02
Filed: 1984-02-20
Abstract: PURPOSE:To prevent sliding portions from being lubricated insufficiently due to oil foaming, by protrusively providing a disk flange on the peripheral portion of a cylinder block located below the surface of lubricating oil, so that the disk flange is placed in contact with the inside surface of an enclosed container, and by providing oil passages in the disk flange. CONSTITUTION:The peripheral portion of a disk flange 17 protrusively provided on the peripheral portion of the end bearing 6 of a compressor in an enclosed container 1 is placed in contact with the inside surface of the container. Plural holes 17a extend as oil passages through the flange 17. As a result, lubricating oil 14 is divided into an upper and a lower layers by the flange 17 so that even if an oil foaming phenomenon takes place on the surface 14a of the lubricating oil 14 which is in contact with coolant gas, bubbles do not reach the lower layer. For that reason, the lubricating oil supplied to sliding portions is always retained in the enclosed container 1.

Filed: 1985-02-18
Abstract: PURPOSE:To prevent decrease in capacity and lengthen life by covering a conductive substrate to which electrically active polymer is bonded as a film with an electrically inactive resin film. CONSTITUTION:Polystyrene or polyethylene is used as a resin used for covering. When the surface of an electrode is covered with the resin by immersing it into a solution, the resin concentration in the solution is increased so that resin molecules are interwined each other in the solution. When it is covered by vapor deposition, the resin is placed in the bottom of a container, and the electrode is hung above the resin, and the container is heated under a reduced pressure. Adhesion of an electrically active polymer to a conductive substrate is increased, and decrease in capacity caused by repeated charge-discharge cycles is prevented and life is lengthened.

Next, the temporary wirings are removed and a wiring is formed in each chip region. At that time, the wirings are formed by use of a predetermined wiring reticle according to the number and positions of defective element blocks 3A existing in the chip region 2. For example, one of the four blocks is a defective element block 3A, four reticles for chip region are used according to the position of said defective element block 3A. Shaded parts 10 are the regions the blocks in which are not used, namely, the regions where wirings are not formed.

Title: Shifting device under inoperative condition of continuously variable transmission
Inventor: KANOU KENSHIROU
IPC: F16H61/00
Filed: 1986-02-13
Abstract: PURPOSE:To restart a vehicle at a low gear speed upon engine stall, by setting a strength of a pusher spring to reduce a press contact force of a planetary cone against a ring at low loads, and moving the ring during the stop of the vehicle. CONSTITUTION:Only when a reaction force generated from an automatic pressure governor mechanism 4 at low load is less than a driving force required for driving an output shaft 3 from a planetary cone 2, a strength of a pusher spring 6 provided in a differential planetary mechanism type continuously variable transmission A is set to be greater than the required driving force, so as to complement the reaction force. Therefor, only when a load factor is lower than a certain value in the above case, the pusher spring 6 is required. Accordingly, even when a vehicle is stopped, a ring 7 may be moved to effect a shift operation. In the case that an engine stall occurs during high-speed running, for example, the shift operation may be carried out at this time, and a vehicle may be easily restarted at a low gear speed.

Filed: 1988-02-12
Abstract: PURPOSE:To improve an S/N and to miniaturize the title discriminator by winding a first coil, whose both edges are short-circuited and a second coil for signal detection, to an annular core, whose magnetomotive force and magnetic flux density have almost proportional relation and permeability is almost constant. CONSTITUTION:Coils 2 and 3 are operated as a secondary coil to a detected signal line 4, which is a primary coil, and a low frequency current and a high frequency current flow in the signal line 4. Then, the magnetomotive force is generated in a core 1. In correspondence to this generation of the magnetomotive force, electromotive force is generated in the coil 2, however, since the both edges are short-circuited for the coil 2, a current to cancel the change of a magnetic flux in the core 1 flows to the coil 2. Here, since the permeability is almost constant from a low frequency area to a high frequency are in the core 1 and the core 1 has a BH characteristic, which is almost linear, with the almost proportional relation between the magnetomotive force and the magnetic flux density, the inductive reactance of the coil 2 goes to small in the low frequency area and goes to large in the high frequency area. Thus, a low frequency component is canceled and the coil 3 outputs only a high frequency component.
