Filed: 1987-12-21
Abstract: PURPOSE:To obtain an epoxy resin molding material for semiconductor sealing, excellent in humidity resistance and moldability as well as low-stress property, by adding an epoxy-modified polybutadiene to an epoxy resin. CONSTITUTION:This epoxy resin molding material contains an epoxy-modified polybutadiene. It is usually desirable that the epoxy equivalent of the polybutadiene is about 150-1500. When it is below 150, no effective low-stress property can be attained. When it is above 1500, the strength of the molding material is decreased undesirably and flashes are formed. It is particularly desirable that the epoxy equivalent of the polybutadiene is about 200-400. It is desirable that the polybutadiene is added in an amount of about 0.3-5wt.% based on the total weight of the epoxy resin molding material for sealing.

Title: Floatation treatment
Inventor: KATO ISAMU
IPC: C02F1/24
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To enable safely and surely obtaining treated water of good quality in a floatation treating method in which after dissolved gas containing water is fed to the lower part of a feed well, it is raised in the feed well by specifying the average rising flow velocity of water in the feed well. SOLUTION: In a floatation device whose feed well is of open type, raw water and pressured water flow into a floating tank through a feed well 3 from inflow pipes 4, 5 respectively to perform solid-liquid separation. And the treated water rises between a tank body 1 and an inner tank 2 from the lower end of the inner tank 2 and is discharged from a treated water trough 6. On the other hand, floated scum is raked up by a scum rake 7 and is filled into a scum box 8 and is discharged from a discharge port. In this case, the average rising flow velocity of water flowing in the feed well 3, that is, mixed water of the raw water and pressured water is set within the range of 0.05-0.22 m/sec. In this way, floating separation property of suspended matter stuck to fine bubbled is improved to eliminate a decrease in water quality of the treated water.

Filed: 1991-12-09
Abstract: PURPOSE:To warm intake air with exhaust heat as well as to improve the extent of a space efficiency in an engine room by changing a long inlet pipe, having a heating part between an inlet port and an exhaust port situated in and around an exhaust pipe, over to a short inlet pipe using a part nearer to the exhaust port than the heating part in common. CONSTITUTION:Four branch intake pipes 20A-20D are connected to intake manifolds 14A-14D of respective cylinders 11A-11D of an engine 10. When first valve 22A-22D and second valves 38A-38D are closed, fresh air passes through the longest passage (long intake pipe) from a throttle valve 36 and receives heat from two exhaust pipes 18A, 18B. When the first valve 22A-22D are opened, the fresh air enters the straight branch intake pipes 20A-20D (short intake pipe). Doing a proper use like this, fuel consumption is improved, dispensing with any intake pipe in a separate system, and the extent (of space efficiency is thus improved.

Title: Thin film forming device
Inventor: TAKI MASAYOSHI
IPC: C23C14/28
Filed: 1992-12-04
Abstract: PURPOSE:To increase film forming speed. CONSTITUTION:A target 3 is arranged in a chamber 1 and a substrate 6 is arranged opposite to the chamber 1. A space formed between the target 3 and the substrate 6 is surrounded by a sticking preventing plate 13. When the target 3 is irradiated with laser beam L after the chamber 1 is evacuated, atoms is emitted from the target 3. A part of the atoms flies to the substrate 6 and another part flies to the inside wall surface of the sticking preventing plate 13. The atoms flying to the inside wall surface of the sticking preventing plate 13 fly to the substrate 6 without sticking to the inside wall surface of the sticking preventing plate 13 as a fluorine based oil is applied on the inside wall surface of the sticking preventing plate 13. As a result, since the whole atoms emitted from the target 3 finally fly to the substrate 6, the film forming speed of the thin film formed on the substrate 6 is increased.

Abstract: PURPOSE:To obtain the title sensor capable of measuring the concn. of oxygen contained in a solution to be measured with high accuracy even if calibration is not performed. CONSTITUTION:A measuring chamber 13 having an electrolyte received therein is formed so as to be surrounded by the upper surface 3a of a first insulating substrate 3 and the side wall 9a of the window part 9 of a second insulating substrate 11.
