Abstract: The present invention is formed by detecting the charged particles generated during film peeling and fragility breaking, so that it is possible to specify a peel occurring time and a fragility breaking time, with a high sensitivity and a high accuracy. In this way, it becomes possible to correctly measure the peel strength and the fragility breaking strength. The method of the invention comprises the steps of pressing an indenter into a test object and measuring an indentation load as well as an indentation depth, while at the same time detecting charged particles omitted from a peel starting point or a breakage starting point; specifying a peel occurring time and a fragility breaking time when charged particles are increased; measuring a peel strength and/or a fragility breaking strength.

Abstract: A coater blade and backing roll combination contains a coater blade having an elastic steel blade with a wear-resistant coating formed thereon. The wear-resistant coating has a hardness greater than that of the elastic steel blade and is provided on an edge of the blade to define a coater surface for contacting with a moving surface of coated paper on the backing roll. The backing roll has a concave outer surface having a curvature corresponding to a quadratic equation and the coater surface has a concave curvature corresponding to the quadratic equation.

Abstract: A roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer is disposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.

Abstract: An automotive seat having a seat belt buckle holder is disclosed, which includes a seatback part having a pad covered with an outer skin member, and a seat belt assembly having a belt equipped with a buckle. The pad is partially cut away to form a rectangular recess which is so sized as to accommodate the buckle. The outer skin member is cut in L-shape for providing the outer skin member with an openable part. The openable part is detachably fastened, by means of a fastener, to the pad.

Abstract: A car seat comprising a seat slide mechanism, a seat reclining mechanism and, walk-in system. The walk-in system is provided with a wire to unlock the seat slide means and the wire is arranged to loosen when the seat-back is swung backward by the reclining mechanism.

Abstract: A lens-fitted photographic film package having exposure structure includes a light-tight securely closed film casing provided with a taking lens, a film container containing an unexposed film, a removable light-tight film container having a spool to which a leading end of the film is attached, and a film-advancing member externally operable for rotating the film spool to wind the film around the spool in the light-tight film container one frame every exposure.

Abstract: A method for connecting two circuit boards characterized in that by using rubber connectors, each having an open part for receiving circuit boards, an edge of a first circuit board requiring connection inserted into the open part of the rubber connector, followed by pressing a second rubber connector against the circuit board to complete connection of the two circuit boards.

Abstract: A method of magnetically recording photographic pictures into a magnetic disc contained in a magnetic disc pack. According to this method of recording image signals of the photographic pictures, the photographic pictures formed on a roll-shaped print are successively taken by a video camera before being cut from one frame to another, and the image signals of the photographic pictures are magnetically recorded into a magnetic disc. In consequence, the flow of the existing photographic processing laboratory system is not impaired. Further, photographed subjects of the video camera are not separated from one another, so that the photographed subjects can be processed easily at the time of video taking.

Abstract: A DAP (Deformation of Aligned phase of Nematic) type liquid crystal display is enabled with a voltage having a periodically variable effective value. The displaying color of the DAP type liquid crystal display is changed by cyclic variation in the effective value of the applied voltage.

Abstract: Liquid crystal material suitable for use in small display devices and consisting of one or more biphenyl or terphenyl compounds and one or more ester compounds, whereby low threshold voltage characteristics of one type of compound are complemented by the low viscosity and good response characteristics of the other type of compound, and liquid crystal material having good overall characteristics is achieved.
