Title: Hydraulic device and automatic cluth device
Inventor: SAKATA TAKATOSHI
IPC: F04C14/26
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent generation of high temperature and high pressure immediately after starting a hydraulic pump in a hydraulic device including the hydraulic pump. SOLUTION: A bypass passage branching from a branch point (d) of a discharge path of a hydraulic pump and reaching an oil tank 15 is provided. A flow control valve 20 is provided in the bypass passage. When speed of rotation of a pump axis is low immediately after starting the hydraulic pump, less flow runs in the discharge path 17 and the flow control valve 20 opens. Therefore, oil is returned from the oil tank 15 to the oil tank through the hydraulic pump, the discharge path 17 and the bypass passage so as to be circulated. When the flow increases with increasing the speed of rotation of the pump axis, the flow control valve 20 closes the bypass passage.

Title: Electrolyte-holding member for nonaqueous solution battery
Inventor: KITAGAWA AKIRA
IPC: H01M50/414
Filed: 1983-04-19
Abstract: PURPOSE:To obtain a nonaqueous solution battery having sufficient liquid-leakage resistance, a small increase in its resistance and a small self deterioration rate by mixing an anion-exchange resin with a solvent-resistant fiber different from said resin, then forming the mixture into a sheet which is used as the electrolyte-holding member. CONSTITUTION:Aminoethylcellulose fiber sufficiently immersed in electrolyte before being dried, is mixed with very-fine polyparaphenylenetelephthalamide fiber in a ratio by volume of 1:3. After the mixture is subjected to rolling before needle punching to make a nonwoven sheet, it is made as thin as possible by use of a very small amount of an epoxy adhesive. The thus obtained nonwoven fabric is used to form a paper-like electrolyte-holding member 4 having an anion-exchange ability. After metallic lithium is packed into a case formed by attaching a gasket 2 to a sealing plate 1, electrolyte and the holding member 4 are poured into the case. Next, an outer can 3 packed with a positive mixture is attached to the case to seal the battery, thereby constituting a nonaqueous solution battery. This battery, even when it is left at a relative humidity of 90% for 60 deg.C for 50 days, is not expanded, has sufficient liquid-leakage resistance and a very small increase in its resistance. Besides, the self deterioration of the battery can be minimized.

Title: Anchor screw and pile press-in method using the same
Inventor: KITAMURA MORIO
IPC: E02D7/00
Filed: 1990-03-19
Abstract: PURPOSE:To utilize a lower excavation body as a reaction anchor when a pile is pressed in by dividing an anchor screw into two parts in its axial direction to form a lower and upper excavation body and providing a connection mechanism therebetween to make both bodies independently rotatable. CONSTITUTION:When a fluid is supplied to a connection mechanism 5 provided in an anchor screw 1, a lower excavation body 3 is connected to an upper excavation body 4. When a rotational force is applied to the screw 1 under such condition, both bodies 3, 4 rotate together and excavate the ground. When the ground has been excavated to a predetermined depth, supply of the fluid is stopped to release the connection. Under such condition, a rotational drive source 15 is driven so that only the upper excavation body is rotated to discharge the soil. And then rotation of the body 4 also is stopped so that a jack 21 is extended to press a pile 20 into an excavated bore. Since the lower excavation body 3 has been screwed into the ground at this moment, the pile 20 is smoothly pressed thereinto using said body as a reaction anchor.

Title: Encoder device
Inventor: ITO TAKASHI
IPC: G01D5/244
Filed: 1985-04-01
Abstract: PURPOSE:To detect the position of the rotating disk with a high accuracy by increasing and decreasing the external magnetic field, winding the detecting coil at the ferromagnetic substance in which the strength of the magnetization is rapidly changed and counting the counted value of the impulse-shaped voltage obtained without supplying the electric power to the detecting coil. CONSTITUTION:When rotating disks 9 and 10 fitted to both edges of a permanent magnet 8 are rotated, by increasing and decreasing the external magnetic field close to projecting parts 9a and 10a formed at the circular circumferential part of the rotating disk, the strength of the magnetization of ferromagnetic substances 31-35 is rapidly changed. Consequently, without supplying the electric power to detecting coils 51-55 wound to the ferromagnetic substance, a large impulse-shaped induced voltage can be obtained. Thus, the encoder device can be realized which is comparatively easy in the constitution and little in the power consumption.
