Abstract: A tactile and proximity sensor includes a light source, a light receiving section, and a cover. The light source emits light. The light receiving section receives light and generates a signal providing a result of the received light. The cover includes an elastic body that deforms under external force and that covers the light source and the light receiving section. The cover includes a reflective section that reflects light between the light source and the light receiving section and a transmission section that allows light to pass through in a first direction from the light source and that allows light to pass through in a second direction from the light receiving section.

Abstract: The present invention provides a release sheet and a pressure-sensitive adhesive sheet superior to a release sheet using a conventional ethylene polymer in peeling property. Specifically, in an ethylene polymer to be used for a release sheet for a pressure-sensitive adhesive sheet, (i) the spin-spin relaxation time (T2) of proton of the amorphous region and the ratio of the amorphous region calculated from the relaxation time (T2) are adjusted to certain ranges, or (ii) the bearing ratios obtained by measuring the surface of a release sheet containing the ethylene polymer with an atomic force microscope is adjusted to a certain range.

Abstract: An expoxy resin composition, an epoxy resin cured product obtained therefrom, and a bonding method using the composition are disclosed. The epoxy resin composition comprises an epoxy resin composition comprising (A) 100 parts by weight of an epoxy resin, (B) from 1 to 80 parts by weight of a heat activatable hardener, and (C) from 10 to 100 parts by weight of an aromatic thermoplastic resin powder having a glass transition temperature of 120.degree. C. or more and an average particle diameter of 200 .mu.m or less, said components (A), (B) and (C) being present in a phase separation state.

Abstract: A color image recording apparatus comprises edge detection device with image sensors for detecting longitudinal edges of electrostatic recording paper, and mark detection device for detecting registration marks formed at an equal pitch along the edges of the recording paper. Both edges are detected at a first pass thereof through the edge detection device, and the detected output is stored in a memory. During each of second and subsequent passes, detected data is compared with the initially stored data to correct for expansion and shrinkage of the recording paper. Oblique motion of the recording paper is detected from the timing difference between registration marks formed on opposite sides of the recording paper, which timing difference is used to change line recording timing.

Abstract: An improved automatic roll-in take-up roller for winding and unwinding a continuous sheet-like recording medium is disclosed, which comprises a plurality of cams disposed inside a hollow cylindrical body of the take-up roller for releasably holding a leading end of the recording medium inside the take-up roller, and a switching guide unit disposed immediately upstream of take-up roller for guiding the recording medium toward the take-up roller or a cutter. After the leading end of the recording medium is retained on the take-up roller, the guide unit can be displaced to a position spaced far distant from an outer peripheral surface of the take-up roller so that a large number of turns of the recording medium can be wound around the take-up roller. The cams are arranged along a longitudinal axis of the take-up roller at such a distribution that the recording medium is automatically aligned even when the leading end of the recording paper is inserted into the take-up roller in an obliquely displaced condition.

Abstract: An epoxy resin coating composition comprising a rubber-modified epoxy resin which is obtained by reacting an epoxy resin with a carboxyl group-containing butadiene-acrylonitrile rubber, a phenoxy resin, a metal powder, a curing component, and an organic solvent. This composition is especially useful as a coating for fuel tanks particularly, gasohol fuel tanks. The cured coating from the composition has excellent properties of heat resistance, chemical resistance, corrosion resistance, flexibility and weldability.
