Title: Gas turbine engine
Inventor: URASATO MASAFUMI
IPC: F01M13/00
Filed: 1980-12-10
Abstract: PURPOSE:To release only clean air into the atmosphere, by passing air mixed with oil mist, through lubricating oil in an oil sump so that the oil mist clings to the lubricating oil. CONSTITUTION:The front ends 80A, 90A, 100A of oil pipes 80, 90, 100 secured in lubricating oil return ports 8, 9, 10 are located near the bottom of an oil sump 2. As gas mixed with oil mist and flowing into the oil sump 2 from the return ports 8-10 through the pipes 80, 90, 100 goes out into space 52 through oil 51 staying in the sump 2, the oil mist clings to the oil. The gas is thus removed of the oil mist. As the gas removed of the oil mist through the oil 51 flows to an air breather 44 through the space 52, the gas again gets to contain a small quantity of oil mist. This oil mist is filtered off by a wire net 44B when the gas passes through the air breather 44.

Title: Indicator of electric cleaner
Inventor: HIRANO AKIHIRO
IPC: A47L9/19
Filed: 1987-07-13
Abstract: PURPOSE: To suppress the reduction in sucking force or generation of abnormal sound by providing an indicator bar mounted on an opening and closing plate and pressing the opening and closing plate by the atmospheric pressure to open a hole when the pressure of a dust collecting chamber is reduced by the accumulation of dust in a body. CONSTITUTION: When dust is not so much accumulated in a dust collecting bag 4, an opening and closing plate 10 still closes a hole 8 by the energizing force of a spring 12 to prevent the inflow of air to the dust collecting chamber 3 since the pressure in a dust collecting chamber 3 is not suddenly reduced even by ON of the power source of an electric blower 11. When dust is considerably accumulated in the dust collecting bag 4, the opening plate 10 is moved to open the hole 8 since the pressure in the dust collecting chamber 3 is suddenly reduced by the load of the dust collecting bag 4 when the power source of the electric blower 11 is on, and the force of the air added to the opening and closing plate 10 overcomes the pressure in the dust collecting chamber 3 and the force added to the opening and closing plate 10 by the spring 12.  The air flows from a chamber 7 into the dust collecting chamber 3 to cool the electric blower 11. Since an indicator bar 13 mounted on the opening and closing plate 10 is also moved, the accumulation of dust in the dust collecting chamber 3 can be found by the change of the position of the indicator bar 13.

Abstract: PROBLEM TO BE SOLVED: To improve a yield without generating the traces of cutting, etc., by a method in which the central part of an ingot is subjected to boring and peripheral machining and the ingot is cut slice by slice. SOLUTION: In the boring and peripheral machining of the central part of an ingot 1, a drill 2 which has a longitudinal extraction hole 3 in the middle and a cutting blade 4 of diamond, etc., in the lower end part is used, a coolant of water, oil, etc., having a prescribed pressure is passed forcibly through the hole 3, and the temperature of the cutting blade 4 at the end of the drill 2 is prevented from increasing. By passing the coolant forcibly through the hole 3, chips generated in the machining of the ingot 1 are discharged outside with the coolant. Since the boring and the peripheral machining can be carried out in the state of the ingot 1, in the next process of cutting, the cutting of unnecessary parts is eliminated, curtailing a cutting time.

Title: Method and device for controlling rolling of metallic strip
Inventor: KANEYASU SHINTARO
IPC: B21B39/14
Filed: 1994-07-26
Abstract: PURPOSE:To surely prevent meandering of a metallic strip even if high tension acts on the metallic strip by setting the rolling force on one side where the metallic strip biases by meandering higher than the rolling force on the other side on the inlet side of a rolling mill thereby preventing the meandering of the strip. CONSTITUTION:Rolls 38, 39 of the rolling mill 2 are so constituted that the rolling forces at both ends of the axial line direction of these rolls vary with each other. The meandering of the stainless steel strip 1 is detected by a meandering detecting means 3 disposed on the inlet side of the rolling mill 2 for this stainless steel strip and the rolling mill 2 is controlled to prevent this meandering by action of a control means. The meandering of the metallic strip 1 is detected on the inlet side of the rolling mill 2 and the rolling forces of the rolling mill are so controlled as to make the rolling force on one side where the metallic strip progresses by meandering and biasing larger and to make the rolling force on the other side where the metallic strip meanders to part from the mill smaller. As a result, the component of force acts in the strip width direction from the one side to the other side, by which the metallic strip is moved to the other side and the meandering of the metallic strip on the inlet side of the rolling mill is prevented.
