Title: Screw coupling type propelling pipe structure
Inventor: NASU TAKU
IPC: F16L15/04
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a screw coupling type propelling pipe structure capable of reducing damage due to friction with sediment or the like in propulsion and reducing the resin material cost and construction cost of a resin coating. SOLUTION: A screw coupling type propelling pipe 10 is formed by screw- joining an outer resin coated steel pipe 10a coated with resin 13 and an outer surface resin coated steep pipe 10b. The resin coating of a screw part 11 outer surface of a succeeding outer resin coated steel pipe 10a with respect to the propelling direction is a resin coating having the same hardness as that of the resin coating 13 of the outer surface resin coated steel pipe 10a, and on the other hand, a resin coating 14 having a hardness higher than that of the resin coating 13 of the screw part 11 outer surface of the outer surface resin coated steel pipe 10a is applied to the screw part 12 outer surface of the preceding outer surface resin coated steel pipe 10b.  A resin coating having a higher hardness is applied only to a portion liable to be damaged in propulsion, so that the resin coating material cost and the resin coating construction cost including off-line can be reduced.

Title: Electronic oil pressure controller of internal- combustion engine
Inventor: SAITOU ATSUSHI
IPC: F01L9/10
Filed: 1983-03-26
Abstract: PURPOSE:To simplify the construction of oil pressure source by using the same oil pressure source to supply working oil of the servo mechanism of a fuel injector and working oil which is applied for driving an intake and discharge valve. CONSTITUTION:Fuel is supplied for the nozzle part 32 of a fuel injector by a fuel supply pump 69 which is driven by an engine 68. By a working oil supply pump 76 which is driven by the engine 68, the same working oil is supplied for the servo mechanism part 33 of the fuel injector and a valve mechanism part 62 which opens and closes a valve 36. Quantities of working oil supplied for those parts are controlled by solenoid parts 31 and 63 which are controlled by an electronic controller R, respectively. Since the oil as working oil is fed from a system different from a fuel system, the fuel injector and the valve mechanism may be provided with superior responsibility even if the quality of fuel is low. Since the working oil supplied has one oil pressure source, it may be made simple.

Title: Thermoplastic resin film winding method
Inventor: HOSOI MITSUGI
IPC: B29L7/00
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To suppress winding creases so as to obtain a wound roll with an excellent wound form by controlling winding-out tension to the specific percentage of winding tension at the time of winding out a thermoplastic resin film from one film roll and winding it on the other roll to obtain a product roll. SOLUTION: Optimum constant winding tension differs depending on the sort, stretching degree or thickness of a film. In case of a biaxial stretched polyester film of about 5μm in thickness, the optimum constant winding tension is normally about 3-8kg/m, desirably 4-6kg/m. Unwinding tension, on the other hand, is to be lower than winding tension and is controlled to be in a range of 40-80% of winding tension. In case of unwinding tension being less than 40% of winding tension, travel of the film is not stabilized so as to generate even more creases. In case of exceeding 80%, creases are generated due to winding crease included in a raw cloth roll so as not to be able to obtain a wound roll suppressed in winding creases.

In the spiral swirling/separating chamber 2, foreign matters (large) 8 is imparted with a turning flow while foreign matters (small) 9 and the cleaning matters 10 are imparted with a swirling flow by a swirling unit 3 disposed in the center of a shaft. The heavy foreign matters (large) 8 are precipitated on a bottom plate 7 while the foreign matters (light) 9 and the cleaning matters 10 float temporarily and then the foreign matters (light) 9 fall down to the lower side when passing through a spiral slit 5 due to the difference of shape.  The cleaning matters 10 are floated upward and introduced through a cleaning matter outlet pipe 6 toward a circulation/collection line or a counter.

Filed: 1988-03-09
Abstract: PURPOSE:To protect an induction motor against an overcurrent by preventing a controller for an electric rolling stock from starting when the difference between the maximum value and the minimum value of the rotating speed of the motor becomes larger than a predetermined set value. CONSTITUTION:A switch 4a is switched to a minimum value detector 1 side at the time of power drive, and a slip frequency is added by an arithmetic unit 3 to the minimum value FMIN of signals FM1-FMn representing the rotating frequencies of induction motors M1-Mn as an inverter frequency signal FINV. On the other hand, the switch 4a is switched to a maximum value detector 2 side at the time of braking, and the slip frequency is subtracted from the maximum value FMAX by the unit 3. A logic unit 5 subtracts the value FMAX and the minimum value FMIN, and when the difference is larger than a predetermined set value, a signal OFF for preventing an inverter from starting is output.
