Abstract: PURPOSE:To reduce the weight and to increase the sound absorbing ability while maintaining the rigidity and preventing the underwater sound absorbing wedge from bending by its own weight by setting a tapering direction almost at right angles to the surface of the plane sound absorbing wedge and joining another plane sound absorbing wedge. CONSTITUTION:A tapered plane sound absorbing wedge 1a and plane sound absorbing wedges 1b and 1c which are adhered almost at right angles to both surfaces of the sound absorbing wedge 1a while their tapering directions meet each other form a cross-shaped section, and sound absorbing wedge fitting bottom plates 2a-2c are fitted to the sound absorbing wedges 1a-1c. The bottom plates 2a-2c of the sound absorbing wedge 1 are coupled with a fitting base plate 3 with bolts, and cross-shaped sound absorbing wedges 1 are arranged on the fitting base plate 3 to form a sound absorbing wedge assembly. Consequently, while the rigidity is maintained and the wedge is prevented from bending by its own weight, the weight is reduced and the sound absorbing ability is improved.

IPC: C23F1/08
Filed: 1978-03-24
Abstract: PURPOSE: To enhance etching accuracy; increase etching speed; and simplify an etching process by cooling a material to be etched to below 20°C in a container and treating the cooled material with cooled HF gas.  
     CONSTITUTION: Material 14 to be etched is mounted on support plate 13 cooled with thermo-element 12 in container 10, and it is kept at below 20°C. On the other hand, HF gas is cooled to 0 W -30°C through transport pipe 20 cooled with refrigerator 22 and heat exchange block 21, and it is introduced into container 10 to etch material 14. At this time, container 10 is held under a press. of about 5.0 Torr with a pump. It is confirmed from laboratory work that etching selectivity is insufficient and this method is not of practical use unless the HF gas is cooled. This method is suitable for etching a silicon substrate coated with a silicon oxide film, a plasma treating process in a conventional method is made unnecessary, and etching accuracy can be enhanced.

Title: Die for die-casting
Inventor: SATOU KIMINORI
IPC: B22D17/22
Filed: 1994-03-04
Abstract: PURPOSE:To provide a die for die-casting, in which a pin for hole as cast can surely be used for a long service life, by bringing the whole periphery of a part of the pin for hole as cast projecting into a cavity into uniform contact with molten metal. CONSTITUTION:In the casting by means of the die 2 for die-casting, the molten metal M is supplied to a sprue 30, and pressed into the cavity 40 through a runner 32 and gates 34A, 34B by advancing a plunger 14. The molten metal M flowing from the first gate 34A collides against the projecting part 22 of the pin 20 for hole as cast and passes through gaps 36A, 36B on both sides of the pin 20 for hole as cast. Plural gear-shaped protruding parts are formed on the outer peripheral surface of the projecting part 22, and inflow pressure of the molten metal M is received by these protruding parts. Since the gap 36A is narrower than the gap 36B, the flow rate of the molten metal M passing through the gap 36B becomes larger than that passing through the gap 36A and the pin 20 for hole as cast is turned counterclockwise. In such a way, the pin 20 for hole as cast can surely be turned at the time of feeding with pressure the molten metal M so that the whole periphery comes into uniform contact with the molten metal.
