IPC: E02D3/12
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To appropriately from a soil improvement element in soil while restraining the discharge of slime. SOLUTION: A communicated first nozzle 50, a second nozzle 52 concentric with the first nozzle 52, a third nozzle 56 located upstream from the first and second nozzles 50, 52, and a fourth nozzle 58 located further upstream from them are formed at the end of a rod member 12. A soil is excavated by insertion of the rod member 12 into the ground, and after the rod member 12 is inserted to a predetermined depth, the A- and B-liquids of a quick-setting material are ejected respectively from the first and second nozzles 50, 52. Also, as clean water at a predetermined pressure is ejected from the third nozzle 56, the rod member 12 is rotated and gradually drawn back to construct a soil improvement element containing the setting material in a predetermined area under the ground.  Clean water is ejected from the fourth nozzle 56 in such a manner that the range of the clean water ejected is smaller than the range of the clean water ejected by the third nozzle 56 to form a curtain of clean water in a gap between the rod member 12 and ambient soil.

Title: Malicious call retrieval system in mfc signal system
Inventor: HAYASHI KUNIHIKO
IPC: H04M3/42
Filed: 1988-04-18
Abstract: PURPOSE:To eliminate the need for holding an expensive interstation relay line for a long time by retrieving the location of a caller subscriber from a caller subscriber number printed out on a typewriter of an incoming station. CONSTITUTION:An incoming station 9 receives a forward signal 1 including an incoming subscriber number and connects the signal to an incoming subscriber 4. When the incoming subscriber 4 of the incoming station 9 recognizes the service of malicious retrieval service, the exchange of the incoming station 9 sends a backward signal 2 signifying the caller subscriber number request from a resistor 10 and receives a forward signal 3 including the caller subscriber number sent from the outgoing station. The exchange of the incoming station 9 stores the caller subscriber number and prints out the caller subscriber number on the typewriter 5 when a malicious call notice (hooking) signal is received. Thus, it is not required to trace back the talking line and the long time holding of the expensive interstation relay line is not required.

Filed: 1995-04-21
Abstract: PURPOSE: To introduce an initial defect into a connecting member without the formation of microcracks by forming the rupture part of the connecting member as a weak part being weak in strength in the production process of the connecting member. CONSTITUTION: After silicon nitride raw material is used and press-formed, it is maintained in a nitrogen atmosphere at 1650-1800 deg.C for 4 hours and then sintered to form a rectangular parallelopiped-shaped sintered body 4. Next, a pair of bottomed cylindrical metal cylinder bodies 41, 42 is prepared, and the sectional shape of the hollow part of the metal cylinder bodies 41, 42 almost coincides with the sectional shape of the sintered body 4, and the length of the hollow body is a half of the length of the sintered body 4. The sintered body 4 is severally pressed into the metal cylinder bodies 41, 42 at both its ends to form a state where the end faces of the metal cylinder bodies 41, 42 abut on each other for obtaining a torque limiter. The result of the shear fracture test of the obtained torque limiter is 121kg/cm<2> as fracture load value. Stress concentrates at the central portion of the sintered body 4 located at the abutted part of a pair of metal cylinder bodies 41, 42, and the above central portion therefore ruptures.

Title: Liquid distribution pump
Inventor: SAITO MASAYASU
IPC: F23K5/04
Filed: 1987-04-20
Abstract: PURPOSE:To facilitate stopping of suction by providing a transparent liquid distribution container thereby enabling visual confirmation of the level of liquid sucked from a large container. CONSTITUTION:When small quantity of liquid is sucked from a large container, an outer air flow-in valve 9 in a pump body 2 is fully pulled out, and a hose 5 is inserted into the large container. When a bellows tube 6 is compressed and recovered, air in a container 1 is discharged through check valves 8a, 8b to the outer air, and thereby negative pressure is produced in the container 1 so as to suck liquid from the large container. Since the container 1 is molded from transparent plastic, rising liquid level in the container 1 can be confirmed when the pump body 2 is operated continuously. Upon reaching a desired liquid level, operation of the pump body 2 is stopped and the outer air flow-in valve 9 is fully pushed in. Consequently, outer air flows into the container 1 and the pressure in the container 1 is recovered to normal level thus stopping suction of liquid.
