Abstract: This invention relates to a process for preparing bisphenol A of good heat stability by heat-treating bisphenol A containing a very small amount of impurities in a molten state at 185.degree. to 220.degree. C. for 5 to 60 minutes in an oxygen-free atmosphere and the process yields bisphenol A of good heat stability which shows reduced coloration when heated. Bisphenol A prepared by this process has excellent properties relating to color and is particularly suitable as raw material for the manufacture of polycarbonates where the requirement for color is strict.

Abstract: Provided is a stream signal transmission device that can eliminate transmission delay fluctuation with a fast change such as network jitter with high accuracy and synchronize a plurality of streams. The stream signal transmission device includes at least one reception unit that receives a stream signal to which a time code is attached from a network, at least one extraction unit that extracts the time code from the stream signal received by the reception unit, and at least one delay control unit that determines an output time by adding a predetermined fixed delay to a time indicated by the time code extracted by the extraction unit, and outputs the stream signal received by the reception unit after holding the stream signal up to the output time.

Abstract: Embodiments of the invention reduce damage to a disk recording medium when a slider flying above the disk recording medium inside a magnetic disk drive comes into contact with the disk recording medium due to slider vibration. In one embodiment, a magnetic head slider includes a front pad, a rear pad, and carbon protective films. The front pad includes a step bearing surface disposed on the side of a leading end and leading side rail surfaces formed on the step bearing surface. The rear pad includes a rear step bearing surface disposed across a deep groove surface from the front pad and a trailing side rail surface formed on the rear step bearing surface. The carbon protective films are formed on regions including vertices of slider corner portions, respectively. The leading side rail surfaces and the trailing side rail surface are formed substantially on the same level. The carbon protective films are harder than a slider base material and have a small coefficient of friction. The films have a film thickness of about 10 nm or more.

Abstract: Embodiments of the invention provide a slider structure able to lower a flying height compensation ratio caused by a projecting deformation of an air bearing surface of a slider by a flying height control mechanism and afford a change in flying height with a low control power. In one embodiment, a slider is provided with a leading edge, an air bearing surface, and a trailing edge. The air bearing surface includes a front pad, the front pad being made up of a front step bearing surface, leading rail surfaces, and side step bearing surfaces. The air bearing surface also includes a negative pressure groove surface surrounded by the front pad. The air bearing surface further includes a rear pad, the rear pad being made up of a rear step bearing surface formed at the same depth as the depth of the front step bearing surface and positioned on the trailing edge side, a trailing rail surface, an intermediate groove deeper than the trailing rail surface, and a trailing pad surface lying at the same height as the trailing rail surface. The front and both sides of the trailing pad surface are surrounded by the trailing rail surface.
