Inventor: SHODA KANAME
IPC: E02D17/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an earth retaining device having very small frictional resistance in the case of movement. SOLUTION: A moving earth retaining device 1 is so constituted that a pair of right and left sheet pile units 2 and 2 are connected with joint members 3 and, at the same time, that they are moved in a groove with an outside driving device. In that case, a caterpilla 7 capable of rotating along a moving direction in the groove provided to the outsides of the sheet pile unit 2 so as to apply earth pressure in the groove to the caterpilla 7. By the constitution, since the caterpilla 7 is brought into contact with a side wall of the groove to rotate when this earth retaining device 1 is moved in the groove, resistance in the case of movement is very small in comparison with the conventional device even if large earth pressure is applied to the sheet pile units 2.

Title: Pressing device
Inventor: KUBOYA MASAHIRO
IPC: B23Q3/18
Filed: 1992-10-22
Abstract: PURPOSE:To position a work by pressing the work and a jig to a base table under steady force, and to-miniaturize a pressing device and to make it thinner. CONSTITUTION:In a no-load state shown in a figure (a), the flow path of the second hose joint is closed by the second solenoid operated valve to feed compressed air through the first solenoid operated valve from the first hose joint into a pressing device. Since the compressed air pushes the second rubber film 4 from the inside of the pressing device, as shown in a pressurized state in a figure (b), a iron piece 5 leaves a magnet 6, and the second rubber film 4 expands outward. Next when the flow path of the first hose joint 10 is closed by the first solenoid operated valve to stop the flowing in of the compressed air, and the flow path of the second hose joint 11 is opened outward by the second solenoid operated valve, the compressed air flows outward, and the pressing device therefore returns to the no-load state shown in the figure (a).

Title: Stabilized power unit circuit
Inventor: KUMADA KIYOSHI
IPC: G05F1/56
Filed: 1989-11-27
Abstract: PURPOSE:To protect a stabilized power circuit with high accuracy against an overcurrent and a short-circuit by dropping the difference of potentials between both ends of a current detecting resistance connected in series to the emitter of a pnp transistor less than the level of the voltage accordant with protection against the overcurrent or the short circuit. CONSTITUTION:A current detecting resistance R1 is connected in series to a pnp transistor TR 1. An output voltage detection means 10 contains a voltage detecting circuit 11 to detect whether the output voltage Vo is higher than a prescribed level or not. A 1st current limiting means 8 detects the difference of potentials between both ends of the R1 when the Vo is kept higher than the prescribed level. Then the means 8 limits the base current so that said difference of potentials is dropped less than a prescribed holding voltage level when the difference of potentials exceeds the overcurrent detecting voltage level. A 2nd current limiting means 9 detects the difference of potential when the Vo is less than a prescribed level, then limits the base current so that the difference of potentials of the R1 is reduced less than a prescribed holding voltage level different from the holding voltage level set at detection of the overcurrent when the Vo is lower than a prescribed level when the voltage difference goes to higher than the output short-circuit detecting voltage.
