Title: Reducer for groundwater pressure acting on underground structure
Inventor: KOBAYASHI EIJI
IPC: E02D31/02
Filed: 1987-06-18
Abstract: PURPOSE:To cut down the cost of constitution by a method in which an upwardly extending water-conveyance tube is connected to a water-collecting tube set on the bottom of an underground structure, and an effluence tube is connected through an automatic valve to the water-conveyance tube. CONSTITUTION:In case the pressure of groundwater is low, a spherical valve 12 is landed on the soft vinyl chloride spherical valve 11 of a valve seat to interrupt a water-conveyance tube 5 and an effluence tube B. In case the groundwater pressure rises, groundwater collected in a water-collecting tube 3 set on the bottom of an underground structure A goes up in the tube 5 to push up the valve 12 until touched by a valve ball-pressing and drain port 10. The groundwater goes into the lower valve chamber 8 from the tube 5, rises in the aperture between the inner wall of the chamber 8 and the valve 12, enters through the drain port 10 into the upper valve chamber 9, and goes out through the tube 6 to the outside of the structure A.

Title: Production of magnetic head
Inventor: HONKE MASAHIRO
IPC: G11B5/265
Filed: 1984-07-18
Abstract: PURPOSE:To increase the junction intensity and to improve the reliability by securing the linkage between a gap forming groove and a junction groove and heating and melting the adhesive within the groove when blocks are adhered together and deleting air bubbles completely. CONSTITUTION:Center cores 30 and 34, an R/W core 31 and erasion core 35 are joined together and cut at the center part and then sliced to obtain magnetic cores. The linkage is secured between a gap forming groove 42 and a junction groove 40 of the core 30, and a glass adhesive 44 is heated and melted in these grooves. A groove 46 for coil inserting window is formed to the core 31 together with a sloping groove 48 corresponding to the groove 42. The gap distribution accuracy is improved since all core blocks are clamped correctively and fused with heat. In such a way the number of manufacturing processes in reduced and the mass productivity is improved. The air bubbles if produced at the groove bottom part can be deleted out of both the gap forming and junction surfaces since the linkage is secured between both brooves 42 and 40. Thus the quality of a magnetic head core is improved.

Title: Electrodynamic electroacoustic transducer
Inventor: SHIRAKI MANABU
IPC: H04R13/00
Filed: 1988-06-20
Abstract: PURPOSE:To obtain an electrodynamic electroacoustic transducer such as a speaker to generate or receive an acoustic signal having satisfactory accuracy by providing coils for generating oscillating force on both sides of a permanent magnet so that a condition in the case of attracting the permanent magnet and that in the case of repulsing the permanent magnet can be the same in order to oscillate an oscillating body. CONSTITUTION:When an alternating current having a magnitude based on the acoustic signal is applied to coils 23'a and 23'b for generating the oscillating force in a speaker 28, since force to generate a reciprocating oscillation along the axial direction of a magnetic cavity 22' occurs, a permanent magnet 21' oscillates in a reciprocating way along the axial direction in the magnetic cavity 22'. Therefore, an oscillating body 20' fixed to the permanent magnet 21' oscillates and can generate an acoustic signal tone having an appropriate wavelength and an appropriate magnitude. Further, a stator yoke 16' forms a circumferential wall 16'a having a shape to wrap the permanent magnetic 21', closes even a magnetic path generated from the radial direction of the permanent magnet 21' with this circumferential wall 16'a, and prevents the occurrence of radial directional leakage magnetic flux.

Abstract: PURPOSE: To arbitrarily turn a bucket and to retain the turning angle of the bucket by simple mechanism by horizontally displacing sheave group on a main trolley and sheave group on an auxiliary trolley via ropes guided from a drive unit externally installed of the respective trolleys.  
     CONSTITUTION: After turning driving ropes 20, 20' are engaged from both ends 19, 19' of an equalizer beam 27 on a main trolley 9 to guide drums 22, 22' on respective auxiliary trolleys 10, they are coupled with both ends of a drive unit 23 on a girder 11. In order to turn a tucket 18, sheave group E are turned by the tension and loosening of the ropes 20, 20' upon driving of the drive unit 23. Since the bucket 18 is, however, inclined at turning position, the drums 22, 22' are rotated to move the sheave group F through differential reduction gear 42 and shaft 35 by half in the same direction as the sheave group E to thereby correct the lengths of the respective ropes after the group E when the ropes 20, 20' are drawn or loosened in movements.

Filed: 1987-06-17
Abstract: PURPOSE:To decrease the number of programs to be produced by writing the test data stored in a storing means into a cache memory when this memory is tested and then reading the stored test data out of the cache memory for the test of the cache memory. CONSTITUTION:The test data to be written into plural cache memories 11 included in a main memory 2 are stored temporarily in a CPU 1. The these test data are written into the memories 11 when these memories 11 are tested. These written data are read out of the memories 11 for test of each memory 11. Thus it is possible to easily produce a test program 21 to each compartment of the memory 11 with no consciousness of the algorithm of each compartment of the memory 11. As a result, the manhour needed for production of test programs can be reduced.

Title: Hammer for escape
Inventor: SEKINO IWAO
IPC: B60R21/00
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To easily break glass even when it is tempered glass, laminated glass or wire reinforced glass by making a head end of a long shaft of a glass holding part into a conical tapered part and furnishing a conical striking part on a head end of the tapered part. SOLUTION: A grip 33 is gripped so that a head 2 comes to be upward and a striking part 21 frontward. Thereafter, the striking part 21 is brought down in the F direction powerfully so that it is made contact with glass as breaking object. Consequently, as a glass holding part (outside) and a handle part make an angle at 95 deg., the striking part 21 makes roughly vertically contact with the glass. Thereafter, as stress is concentrated on a head end of the striking part 21, the glass is broken and the head end of the striking part 21 penetrates into the glass. At this point of time, when it is tempered glass having residual stress, breakage spreads over the overall glass due to inside stress and the whole glass is broken.  In the case of laminated glass, as the striking part 21 has an apex angle of 80 deg. when the head end of the striking part 21 penetrates, a first drilled hole is enlarged.

Title: Electromagnetic stirring method for molten steel in mold in continuous casting plant
Inventor: MIYAHARA SHINOBU
IPC: B22D11/10
Filed: 1980-10-30
Abstract: PURPOSE:To prevent slag inclusion and to produce an ingot of good quality by installing a pair of electromagnetic stirrers of specific length in specific positions near the meniscus on the long sides of a mold. CONSTITUTION:Electromagnetic stirrers 2, 2' give horizontal rotating flow to the molten steel in a mold 1, and the legnth thereof is slightly shorter than the long side length of the mold 1. They are installed near the upper stream side of the molten steel flow in the mold 1 respectively. Hence, the velocity of flow of the molten steel in the mold accelerated by the stirrer 2 is fairly decelerated in one corner part (b) of the mold 1 because the stirrer 2 is not installed across the  long side of the mold. This decelerated molten steel is again accelerated by the  other stirrer 2', after which it is again decelerated in the other corner part (a),  and from this point on, the similar cycles are repeated and the molten steel is  uniformly and electromagnetically stirred in a horizontal direction. Thereby, the  slag inclusion into the molten steel near the meniscus is prevented.
