Title: Liquefaction prevention structure of ground, its construction method, and ground improving method
Inventor: KOBAYASHI KAZUTO
IPC: E02D3/10
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent liquefaction of weak ground by having a plurality of circular-arc gravel drains connecting respective base ends to a gravel shaft and its lower part. SOLUTION: In the neighborhood of a structure 1, at least one small-sized shaft 4 is excavated until a bottom part reaches the layer of earth 2 having possibility of liquefaction. Next, excavation is performed by a circular-arc pipe jacking method as a circular-arc hole 5 extending to the layer of the earth 2 from the lower part of one shaft 4 reaches the other shaft 4, and respective circular-arc holes are filled with gravel. The gravel is charged into the shaft 4 to be filled. Thereby a plurality of circular-arc gravel drains 6 can be installed in the layer of the earth 2. Since excessive gap water produced in an earthquake is quickly drained on ground through the gravel shaft of both the gravel shafts from each circular-arc gravel drain 6, the liquefaction of the layer of the earth 2 can be prevented.  In addition, since the gravel shaft can be installed near sideward of the structure 1, a ground occupying area can be lessened.

Title: Medium accumulating mechanism
Inventor: KATO KIYOTAKA
IPC: B65H31/38
Filed: 1990-07-16
Abstract: PURPOSE:To accumulate media dropped in an accumulation section without being shaped in disorder by continuously reciprocating both side guides via a link mechanism so as to vary in space. CONSTITUTION:A link mechanism 14 provided for reciprocating side guides 4, 5 so as to vary in space is driven by a motor 25. When medium 1 is carried in a side-shifted or oblique-running state, the medium 1 runs on the side guide 4 or 5 right after the side portion passes in between the entrance of an accumula tion section 2, or an infeed belt 9, and an idle roller 10. Although the side por tion of the medium 1 catches in some case on the side guide slope 4b or the slope 5b without fully dropping in the accumulation section 2, at this time the side guides 4, 5 are put in reciprocation between positions A-A' and between position B-B', respectively, and so the medium 1 slips off the side guid slope. The medium 1 is later aligned with other media 1 for accumulation.

Title: Motor-driven actuator and its controlling method
Inventor: OSATO KAZUMI
IPC: H02K37/22
Filed: 1997-06-25

SOLUTION: In the initial-position recognizing operation of a motor-driven actuator 1, when the command of the initial-position recognizing operation of an output shaft 11 is sent from a controller 20 to a stepping motor 2, the output shaft 11 is rotated until a first stopper 12 of a fourth gear 8 is stopped by one of two second stoppers 13. For example, when the signal having a pulse number corresponding to the rotation of the output shaft 11 rotating by 100 deg. is sent to the stepping motor 2. The first stopper 12 is rotated necessarily until it and the second stopper 13 are engaged to stop by each other, irrespective of the rotational position of the output shaft 11. After the stopping, similar to sending pulse signals to the stepping motor 2 for returning the output shaft 11 by 5 deg., the initial position of the output shaft 11 is recognized accurately.

Abstract: PURPOSE:To reduce influence of retention of chemicals at a downstream side of a wafer holding point and to improve cleaning, rinsing effects of the wafer by providing a lifting member whose one end is vertically moved abutting on the underside of an outer periphery of the wafer to roll to move the wafer between holding rods. CONSTITUTION:A wafer 5 is held by holding rods 6a, 6b and a cross rod 14. When a motor 18 is rotated, a lifting member 11 is moved upward, and the rod 14 lifts the wafer 5. As a result, the wafer 5 is rolled in a direction A with the rod 6b as a fulcrum, and held by the rods 6b, 6c. In this case, the upward position of the shaft 14 is controlled by suitably setting a speed of the motor 18, and the wafer 5 is not lifted more than required. Thus, retention of chemicals at a downstream side of the holding point is eliminated, and cleaning effect of the wafer can be improved.

Title: Picture recorder
Inventor: SHIBAIKE SHIGETO
IPC: H04N1/21
Filed: 1990-07-13
Abstract: PURPOSE:To make the recorder small and to reduce the cost without increasing a load to a circuit by slowing down a read frequency of an image pickup element more than a standard TV frequency at least at recording. CONSTITUTION:A shutter 2 is opened at first at recording and closed again after a prescribed exposure time elapses. Then a switch 6 is thrown to the position of a recording means 8 and a CCD 3 starts reading again and an output is given to a signal processing circuit 5 and the output speed is set to a 30Hz being a half the frequency of the NTSC system. Thus, 1/15sec is required for the scanning of one frame. The signal processing circuit 5 receives the signal and gives an output to the recording means 8, which makes recording. In this case, since an output signal from the circuit 5 has a frequency of 30Hz, only information by 1/2 field is recorded in a recording signal on one track by one head. Thus, since the length of each track is enough to be 1/2 because the information quantity is halved and the cylinder is made thinner by the reduction.
