Title: Building method for continuous underground wall and striation drilling device
Inventor: MURAKAMI SUSUMU
IPC: E02D5/20
Filed: 1988-12-29
Abstract: PURPOSE:To improve the efficiency of building a continuous underground wall by drilling circular holes of the predetermined depth in the ground per predetermined space, and drilling the striation till the predetermined depth in the ground between the adjacent circular holes with a wire saw, etc., and filling the underground wall material in it. CONSTITUTION:Circular holes 3 reaching to the impermeable layer 2 are drilled in the rock-bed along the planned underground water-barrier wall per predetermined space, and a casing comprising a bit is rotated and stroked to be pressed down. Next, the striation 4 having the width as same as the thickness of the planned water-barrier wall is drilled between the adjacent circular holes 3, 3 till it reaches to the impermeable layer. A wire saw, etc., is traveled in parallel to the lower of the bay of a frame 7 in which the wire saw is stretched to cut the space between the circular holes 3, 3, to form the striation 5 corresponding to the width of a cutter. Further, a cut-off sheet 18 made of the synthetic resin, etc., is inserted to be put up into the striation 5. Thereby, the stration of the required minimum can be easily and accurately drilled to the desirable depth.

Title: Moving seat for spectator
Inventor: NAKAJIMA SUSUMU
IPC: G01V15/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To dispense with guide mechanism by installing sensors at a seat body, and advancing the seat body straight by a driving body installed at the seat body while making a track correction between the sensors and detecting markers installed so as not to impair levelness of the floor face. SOLUTION: When a moving seat body 17 starts advancing, first and second advance sensors 14a, 14d are arranged outside of first and second advance detecting markers. When the body 17 starts meandering to the right due to a floor face state or the like, the first advance sensors 14a approaches the first advance detecting marker, and the sensor 14a is put in operation and outputs a signal. Then a main control panel 18 decelerates a first driving part 8a driving the left side part of the body 17 so as to make a track correction of the body 17 to the left. When the sensor 14a goes away from the detecting marker, operation is stopped, and the main control panel 18 equalizes the speed of the driving parts 8a, 8b again. When the body 17 meanders to the left, the sensor 14d is put in operation, and the driving part 8b is decelerated to correct the body 17 to the right. The floor face of a gymnasium or the like can therefore be used safely.

Title: Balanced transmission circuit
Inventor: MATSUNAGA HIROSHI
IPC: H04L25/08
Filed: 1989-12-25
Abstract: PURPOSE:To allow a transmission circuit itself to identify whether cable interconnecting equipment is broken or a power supply of a sender circuit is interrupted by connecting a variable resistive element as a collector load of a transistor(TR) of an emitter follower circuit. CONSTITUTION:When a -5.2V power supply is interrupted, no voltage is applied to MOSFETs 12, 13 and the MOSFETs 12, 13 reach a high impedance state. As a result, a current required to activate TRs Q13, Q4 does not flow to bases of the TRs Q13, Q14 being components of an emitter follower circuit 11. Thus, inputs of a receiver side amplifier 4 are not all at a high level and the input is kept almost to -2V. Thus, the power interruption information is sent to the receiver side by the transmission circuit itself.
