Title: Vessel with bow bulb
Inventor: ITO EIICHI
IPC: B63B1/40
Filed: 1985-04-17
Abstract: PURPOSE:To improve wave reducing effect in a ballasted-draft condition and decrease the ship resistance, by arranging a cutting at the upper forward portion of a bow bulb, and furnishing a rotary body which rotates around the axis perpendicular to the center surface of the ship at the cutting, to rotate freely by a driving unit. CONSTITUTION:A cutting 1a is formed at the upper forward portion of a bow bulb 1, and a rotary body 5 is placed inside the bow bulb 1. The rotary body 5 has a form similar to the upper forward portion of the bow bulb 1 at its periphery, and is formed to rotate freely by a driving unit 8 around the axis which is perpendicular to the center surface of the ship. When the upper half of the bow bulb 1 is exposed above the sea level in a ballasted-draft 3 condition, the water flow around the top of the bow bulb is converted by rotating the rotary body 5, and growth of waves is reduced by the exposed bow bulb 1. As a result, the resistance of the ship as a whole can be reduced.

Title: Injection work process
Inventor: TAKEMOTO KUNIHIRO
IPC: E02D3/12
Filed: 1978-07-07
Abstract: PURPOSE: To provide an injection work process whereby a simple and assured packer effect can be obtained as compared with the use of a conventional packer set and the injection pipe can be rotated and moved upward and downward freely.  
     CONSTITUTION: First a casing tube 1 is built in the ground at a predetermined location. Then an injection pipe 2 thinner than the tube 1 is inserted coaxially in the tube 1, with the bottom end reaching the lowest end of the injection zone 6. A rapid-curred or elastic filler 3 is filled in the lower portion of the gap between the tube 1 and the pipe 2. After curing of the filler 3, a caulking material 4 is filled in the upper portion of the gap. Then an injection liquid is injected into the zone 6 through the pipe 2. The filler 3 and the caulking material 4 act as a packer, to prevent assuredly the liquid from escaping upward along the peripheral surface of the pipe 2.

Title: Method and apparatus for purifying sewage and aerobic bacteria holding carrier
Inventor: NAKABASHI TAKAO
IPC: C02F3/10
Filed: 1995-04-07
Abstract: PURPOSE: To simplify the adjustment of the circulating amt. of treated water by always returning a predetermined amt. of treated water in a treatment tank using aerobic bacteria to the upper part of an anaerobic filter bed tank by an air lift pump and to always circulate a definite amt. of treated water and to prevent the outflow of fine 88 to obtain highly treated water. CONSTITUTION: Biologically filtered treated water in a treatment tank 5 is always returned to the upper part of an anaerobic filter bed tank 3 at a constant flow rate by a circulating air lift pump 33. Therefore, sewage is recycled from the anaerobic filter bed tank to the treatment tank 5 and, even if the circulating amt. of the air lift pump 33 is changed, it becomes unnecessary to adjust the water sending amt. of the air lift pump 33 sending water from a solid removing second chamber 2 to the anaerobic filter bed tank 3. Even when the air lift pump 33 is operated, sewage is always recycled to three tanks 2, 3, 5 and, therefore, the temporary lowering of the water level in the treatment tank 5 is eliminated and a definite amt. of treated water can be always circulated.

Filed: 1986-04-08
Abstract: PURPOSE:To eliminate the fluctuation of the gap space due to the fastening load of a fixing screw when a head base is fixed to a rotary drum by means of said screw, by providing a relief plane having a difference of level to the fixed plane of the head base at said fixed plane side to the head base so that at least the inner end part of a slit groove is included in the relief plane. CONSTITUTION:A relief plane 14 having a difference of level to the fixed plane 12 of a head base 2 at this plane side is provided to the base 2 so that at least the inner end part 13 of a slit groove 7 is included by the plane 14. Therefore no contact is produced between a rotary drum and at least the part 13 of the groove 7 when the base 2 is fixed by a fixing screw 9. Thus the peripheral stress state of the groove 7 has no change even with the fastening state of the screw 9 and therefore the groove 7 has no change of its own width. This causes no change of the gap space between head chips 3 and 4, which improves the VTR performance after a head is incorporated.

Consequently, the plugs 13 and 14 press switch pieces 9a, which flex down to separate contacts 9b. Thus, the wiring from the terminals 8 to the speaker is released and the plugs 13 and 14 and speaker 7 are connected directly.

Abstract: PROBLEM TO BE SOLVED: To improve the cooling efficiency of a pressure tank and reduce the weight of the tank. SOLUTION: A power is supplied to the rectifying/multiplying unit of a Schenkel-type DC high voltage power supply apparatus from an air-core high frequency step-up coil 2 which is housed in a pressure tank 10 filled with high pressure insulating gas. The whole pressure tank 10 is made of aluminum. If the flux from the step-up coil is applied to the tank 10, an eddy current is induced in the inner wall of the tank 10 and a flux cancelling the applied flux is generated and the flux does not leak out of the tank 10. The heat generated by the eddy current is transmitted through the aluminum material and radiated from the outer surface of the tank 10. It is not necessary to cool and circulate the high pressure insulating gas in the tank 10 and the tank 10 and the interior of the tank 10 are never overheated even if a special cooling means is not employed.
