摘要:
A porous article wherein a sulfur containing atomic group is introduced onto at least a part of outer-inner surfaces of the article, a ratio (S/C) of the number of sulfur atoms (S) to the number of carbon atoms (C) on the surface onto which the sulfur containing atomic group is introduced is 7×10−4 or more, a ratio (O/C) of the number of oxygen atoms (O) to the number of carbon atoms (C) on the surface onto which the sulfur containing atomic group is introduced is 0.2 or more, and the ratio (S/C) and the ratio (O/C) are determined by means of an X-ray photoelectron spectrophotometer is disclosed.
摘要:
In a multi-layered printed circuit board on which an LSI having a plurality of power supply pins and a plurality of signal pins is mounted, and a grid array package which adopts the printed circuit board, some or all of the plurality of power supply pins are connected to a power supply pattern via an inductance pattern, thereby reducing generation of radiation noise.
摘要:
Thermoplastic pipes held by a pair of clamp mechanisms are fusibly interconnected. A torque wrench moves one clamp mechanism toward the other clamp mechanism and provides a signal when the force applied is a given value. A locking mechanism is operated in response to this signal to lock the torque wrench in position. The apparatus is programmed to release the locking mechanism at the end of a predetermined time period. Changes in the programmed conditions are effected in response to changes in the size of one of the clamp mechanisms.
