Provided is a porous polytetrafluoroethylene (PTFE) membrane that satisfies the following expressions: 0.2≦F≦4.0; 0.2≦R≦1.0; and R≧−0.1F+0.5, for the Frazier number F [cm3/sec/cm2] and the water entry pressure R [MPa]. This porous PTFE membrane may be a single-layer membrane. This porous PTFE membrane has the properties suitable for use as a waterproof air-permeable membrane, and achieves a good balance between high water resistance and high air permeability.
摘要:
This invention relates to an encapsulated pharmaceutical dosage form comprising a practically insoluble compound or salt and an intracapsular fluid, and/or a surfactant and/or cellulose derivative. It provides for increased oral absorption as compared with the conventional system because, on release of capsule contents from the capsule shell, the practically insoluble compound or salt undergoes diminution in crystal size.
摘要:
A voltage conversion circuit of the present invention is equipped with means for generating a first voltage stabilized with respect to ground potential of a semiconductor integrated circuit device including the circuit, means for generating second voltage stabilized with respect to an external supply voltage of the semiconductor integrated circuit device, and selection means for selecting either the first voltage or the second voltage. The first voltage age, stabilized with respect to the ground potential, is selected and used as the voltage at the time of normal operation, and the second voltage, stabilized with respect to the external supply voltage, is selected and used at the time of aging test. In this case, means for trimming the first voltage and/or the second voltage is, preferably, provided to raise the voltage accuracy.

Provided is a method including: a step A of extruding a mixture containing a polytetrafluoroethylene (PTFE) fine powder having a standard specific gravity (SSG) of 2.19 or less and a liquid lubricant into a sheet using a flat die so as to obtain a PTFE sheet; a step B of rolling the PTFE sheet by passing the sheet between a pair of rolls in a longitudinal direction of the sheet; a step C of stretching the rolled PTFE sheet in a transverse direction of the sheet; a step D of removing the liquid lubricant from the PTFE sheet; and a step E of stretching the PTFE sheet, from which the liquid lubricant has been removed, both in the longitudinal direction of the sheet and in the transverse direction of the sheet, for example, at an area stretch ratio of 150 to 700, so as to make the sheet porous. According to this production method, it is possible to increase the PF value of the porous PTFE membrane.
