Title: Back washing method for filter device
Inventor: MARUYAMA SHINSAKU
IPC: B01D29/62
Filed: 1985-02-25
Abstract: PURPOSE:To perform effective back washing even for a filter device using a membrane having inferior permeability for air and to reduce the amt. of waste liquid produced by the back washing by performing no discharge of liquid contained within the filter device prior to air scrubbing. CONSTITUTION:Dome liquid is discharged by opening a pressurized air line 12 from a dome drain line 14, then the liquid is discharged by closing the line 14, feeding air from the line 12 to pressurize the inside of the dome, then closing the line 12 and opening a waste back washing liquid line 15, until no liquid is contained in the line 15. Or, the back washing waste liquid is discharged by opening the back washing waste liquid line 15, 16 at the same time until no liquid remains in the line 15, and closing the line 16 instantaneously. The line 15 is then closed and a scrubbing air line 13 and a line 15 to be opened during scrubbing are opened, and air is fed from a liquid feeding line 8 and discharged from the line 15 performing thus scrubbing the hollow yarn membrane in the filter device 4 with the air. Finally, a line 13 is closed and a drain line 16 is opened, thus the back washing liquid is discharged completely.

Filed: 1987-02-18
Abstract: PURPOSE:To obtain the same calorific value per unit time as that of propane gas or natural gas even from low calorie gas by providing a gas pressure regulator which can depressurize or pressurize the supply gas pressure. CONSTITUTION:Provision is made of a gas pressure regulator 8 which, being connected to a gas joint 1 formed in a gas passage 1a, can depressurize or pressurize. In a case where the gas to be used is propane gas, a selector switch 10 is first adjusted to propane gas mode, and then, a control device 11 is operated to activated an igniter 6 to make sparks. A gas vale 2 then opens to allow a gas flow from the gas joint 1 to the gas passage 1a. The gas pressure regulator 8 operates so that the pressure of said gas may become the preset gas pressure. The gas jets-out from a nozzle 4 under a regulated gas pressure, and flows to a gas burner 5. A gas flow rate sensor 9 senses whether there is a preset gas flow rate, and, if not, causes the control device 11 to output a control signal to correct the pressure of the gas pressure regulator 8.

IPC: F04C29/04
Filed: 1987-02-18
Abstract: PURPOSE:To enable a compressor to decrease an outflow amount of oil to a system from an electric motor chamber through a delivery pipe, by providing a small duct between a duct, fixed to an enclosed vessel, and the enclosed vessel. CONSTITUTION:Refrigerant gas, which is delivered from a delivery hole 14 containing lubricating oil, is separated into a refrigerant and oil in a delivery chamber 15, and a compressor allows the oil to flow along a wall of an enclosed vessel 10 and the refrigerant gas to flow moving in the inner side from the oil. The refrigerant passes through a communication path 16 of a fixed scroll 1, communication path 17 of a block 9 and a duct 18 position in the bottom part of the communication path 17 being introduced to an electric motor chamber 19, but here the oil, which is disturbed by a small duct 23 positioned between the duct 18 and the enclosed vessel 10, is prevented from being guided to the electric motor chamber 19 by the attraction of the refrigerant. Accordingly, the oil, which is prevented from being attracted to the refrigerant allowed to flow into a system via a delivery pipe 20 from the electric motor chamber 19, drops down to the bottom part of the enclosed vessel 10.

Title: Zero-phase current transformer and its manufacture
Inventor: OKADA SUSUMU
IPC: H01F41/02
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the output sensitivity of a zero-phase current transformer to a zero-phase current by reducing the residual voltage when the current supply to a load is made by arranging a set of conductors which perpendicularly pass through a core in parallel with each other in the same plane which is not parallel with each side of the core. SOLUTION: Primary conductors 3a-3c are arranged in parallel with each other in the same plane so that the conductors 3a-3c may perpendicularly pass through the hollow section of a core 5. The conductors 3a-3c are arranged so that the angle θ between a straight line connecting the cross sections of the conductors 3a-3c to each other and a straight line L0 may become a certain value, namely, the plane may not become parallel with each side of the core 5 and, at the same time, the angle θ is set at the optimum value so that the residual voltage in a secondary conductor may become the minimum. A simple appropriate measure to minimize the residual voltage is to rotate the primary conductors 3a-3c in the window of the core 5.  In this case, the rotation is performed while the residual voltage in the secondary conductor is measured and the optimum angle is decided by finding the inclined angle at which the residual voltage becomes the minimum.

Title: High strength bolt steel
Inventor: ISOGAWA KENJI
IPC: C22C38/22
Filed: 1983-03-07
Abstract: PURPOSE:To manufacture a bolt steel with superior delayed fracture characteristics and high strength by reducing the S and P contents of a low alloy steel as a high strength bolt steel to the utmost and by specifying the ratio between the S and P contents. CONSTITUTION:When a steel bar for a bolt is made of a low alloy steel contg. 0.35-0.45% C, 0.1-0.5% Si, 0.5-1.5% Mn, 0.8-1.3% Cr and 0.05-0.35% Mo, the P and S contents of the steel are reduced to <=0.015% P and <=0.010% S, and the value of S+(1/2)P is adjusted to <=0.015%. Since S forms MnS as an A-type inclusion by bonding to Mn and accelerates delayed fracture, the S content is reduced to <=0.010% so as to restrict the area of the MnS inclusion in the structure to <=0.05%. P segregates on the austenite grain boundaries together with S and makes the boundaries brittle, so the P content is reduced to <=0.015%. A high strength bolt with >=130kg/mm.<2> strength can be manufactured.
