Title: Device for supplying molten metal
Inventor: OKADA YUJI
IPC: B22D35/00
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enable the supplying of molten metal under perfectly closing condi tion and to improve the workability by arranging a degassing treatment appara tus, in which inert gas is fed into the molten metal through a supplying course of the molten metal from a storing vessel to enable bubbling. SOLUTION: At the same time of the degassing treatment of the molten metal 36, this molten metal 36 is fed into the storing vessel 12 and can be supplied from the storing vessel 12 to a fixed quantity vessel 22. When the molten metal 36 fills up into the fixed quantity vessel 22, a valve 18 is closed and a valve 26 is opened and the inert gas is fed into the inner part of the fixed quantity vessel 22 from a pressing passage 24 to pressurize the inner part of this fixed quantity vessel 22. The molten metal 36 in the fixed quantity vessel 22 is supplied into an injection sleeve through the molten metal supplying passage 28 by this pressure.  In such a way, since while continuously executing the degassing treatment to the molten metal 36, the molten metal 36 after the treatment can be supplied, the deterioration of the molten metal 36 caused by the contact with the air can be prevented, and the workability is improved.

Filed: 1988-07-01
Abstract: PURPOSE:To enable low-cost, simplified identification of defective chips by a method wherein the thickness is sensed of an off-spec marking applied to a defective chip for discrimination between defectives and nondefectives. CONSTITUTION:A roller 3, installed at the tip of a guide 2, travels on the surface of a chip 1 fixed immovable on an adhesive sheet 4, sensing a difference  x, attributable to the thickness of an off-spec marking 8, between a defective chip 1a and nondefective chip 1b. The difference  x is utilized in discriminating between the defective chip 1a and the nondefective chip 1b. Owing to the roller 3, the chip surface is protected from damage. A platform 7 is placed under the adhesive sheet 4 before a discriminating process so that the adhesive sheet 4 will not experience distortion under the moving guide 2. The result is a low- cost, simplified method for identifying defective chips, in which method the height difference, in presence between the surface of a defective chip carrying an off-spec marking and that of a nondefective chip not carrying such a marking, is utilized.

Title: Edge for speaker
Inventor: NOGUCHI HIROTOSHI
IPC: H04R7/20
Filed: 1978-12-29
Abstract: PURPOSE:To improve an internal loss and make it possible to make an acoustic pressure frequency characteristic flat by laminating or soaking a thermoplastic resin onto or into a compound material where synthetic pulp and synthetic fiber are mixed and by metling synthetic pulp to bind fiber. CONSTITUTION:Synthetic pulp consisting of high-density polyethylene and acrylic fiber are mixed with rate 1:1 to form a compound material of an approximately 40g/m<2> scale. This compound material is caused to include emulsion consisting of ionomer resin and is dried, and after that, synthetic pulp is melted to form an edge material of an approximately 60g/m<2> scale. Elastic modulus E of this edge material is 4.5X10<9>dyn/cm<2>, and the internal loss is tandelta=0.10. Normally, a paper edge has elastic modulus E of 12X10<9>dyn/cm<2> and an internal loss of tandelta=0.04. Thus, this edge material has no air-permeability and has a large internal loss, so that the acoustic pressure frequency characteristic of the speaker can be made flat.
