Abstract: PURPOSE:To improve liquid sucking and holding properties by carrying out wet-type paper making process by using alkali-containing silicate glass fibers with an average diameter of 0.3-1.0mu and bonding them together without adhesive and then forming a mat-type separator. CONSTITUTION:Alkali-containing silicate glass fibers with an average diameter of 0.3-1.0mu are dispersed in the water whose pH value is kept in 2-3 and are subjected to wet-type paper making process and then a water glass layer that forms a bonding layer is generated on the surface of the glass fiber.

Abstract: PURPOSE:To prevent thin bellows from corroding while maintaining the cooling performance for enhancing the reliability of bellows by a method wherein the inside of holding members is filled with corrosion resisting means while radiating structures are protruded inside a liquid channel to seal the liquid channel. CONSTITUTION:The inside of cooling structures 13 is filled with a corrosion resisting means 14, i.e., grease 14 while radiating parts 13-4a protrude inside a liquid channel 12b of the main body 12. The holding members of the cooling structures 13, i.e., flanges 13-2 are fixed to respective openings 12a of the main body 12. Thus, a cooling solution fed from a pipe 2-3 does not infiltrate into bellows 13-1 filled with the grease 14 but runs through the liquid channel 12b. At this time, the cooling solution cools down the protruding radiating parts 13-4a resultantly cooling down the heat conductive metal fittings 13-3 heated using an LSI 1-1. Through these procedures, respective LSIs 1-1 closely adhering to the contact surfaces 13-3a of the heat conductive metal fittings 13-3 can be cooled down so that the corrosion resistance of the bellows 13-1 as well as the maintenance of high cooling performance may be assured.

Title: Memory chip
Inventor: BROX MARTIN
IPC: G11C7/22
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To obtain a memory chip which can prevent an IC from entering a troublesome operating mode during a power enhancement operation by a method wherein an internal operating voltage and a control voltage which expresses the state of the internal operating voltage are generated in response to the application of an operating voltage which is supplied from the outside. SOLUTION: A chip ready (CHRDYp) signal is supplied to a control circuit. When an internal voltage which is generated to operate a memory circuit reaches an operatable level, it becomes active. The control circuit generates an output signal as an internal row address strobe (RINTp) signal. An RASn signal is in an inactive state. However, the CHRDYp signal is in an active state. Then, the RASn signal is shifted to an active state from the inactive state. On the other hand, the CHRDYp signal becomes active only when it is still active. Thereby, when a memory chip is in a power enhancement operation, it is guaranteed so as not to be operated in an undesired mode.
