摘要： First, a mixture of a polytetrafluoroethylene fine powder and a liquid lubricant into a sheet-form body extending in a first direction. Next, the liquid lubricant is removed from the sheet-form body. Then, the sheet-form body is stretched by a factor of 40 to 250 in the longitudinal direction at a temperature equal to or higher than a melting point of polytetrafluoroethylene, and the stretched sheet-form body is further stretched by a factor of 3 to 40 in the width direction. Thus, a highly air-permeable porous polytetrafluoroethylene membrane is obtained.

摘要： The present invention provides a water-proof sound-transmitting membrane including a polytetrafluoroethylene (PTFE) porous membrane, in which the waterproofness is enhanced further with little lowering of the sound transmittance. The water-proof sound-transmitting membrane includes the PTFE porous membrane. The PTFE porous membrane includes a first porous layer, and a second porous layer stacked on and integrated with the first porous layer by a binding force acting between PTFE matrices. The first porous layer and the second porous layer each are composed of PTFE with a number-average molecular weight of 5.0×107 or more determined by a standard specific gravity method. At least one layer selected from the first porous layer and the second porous layer has an average pore diameter of 1 μm or less. The water-proof sound-transmitting membrane has a surface density of 1 g/m2 to 10 g/m2.

摘要： A high-performance information processing technique permitting updating of an instruction buffer ready for effective prefetching to branch instructions and returning to the subroutine with a small volume of hardware is to be provided at low cost. It is an information processing apparatus equipped with a CPU, a memory, prefetch means and the like, wherein a prefetch address generator unit in the prefetch means decodes a branching series of instructions including at least one branched address calculating instruction and branching instruction to a branched address out of a current instruction buffer storing the series of instructions currently accessed by the CPU, and thereby looks ahead to the branching destination address. The information processing apparatus further comprises a RTS instruction buffer for storing a series of instructions of the return destinations of RTS instructions, and series of instructions stored in the current instruction buffer are saved into the RTS instruction buffer.
