    摘要: A pressure sensitive adhesive sheet comprising a substrate, an intermediate layer superimposed thereon and a pressure sensitive adhesive layer superimposed on the intermediate layer, characterized in that the pressure sensitive adhesive layer exhibiting an elastic modulus at 23° C. ranging from 5.0×104 to 1.0×107 Pa, the intermediate layer exhibiting an elastic modulus at 23° C. which is not greater than the elastic modulus at 23° C. of the pressure sensitive adhesive layer, or the intermediate layer exhibiting an elastic modulus at 40° C. of less than 1.0×106 Pa. At the time of working of the back of an adherend having a surface whose unevenness height differences are large, this pressure sensitive adhesive sheet is preferably stuck to the adherend surface to thereby protect it during the working. In particular, when the adherend is to be ground to an extremely small thickness, the pressure sensitive adhesive sheet enables performing the grinding at a uniform thickness without the occurrence of dimples.

    摘要: An image forming apparatus includes a toner supporting roller, an aperture electrode assembly including one or more apertures and associated control electrodes, a controller and a back electrode roller. The toner supporting roller supplies charged toner particles to the underside of the apertures of the aperture electrode assembly. The controller selectively generates a potential difference between each of the control electrodes and the toner supporting roller. A coulomb force generated by the potential difference attracts the toner particles towards the apertures of the aperture electrode assembly. When no voltage is applied to the control electrodes in generating a blank line, no voltage or a reverse voltage is fed to the back electrode roller. Thus, undesired toner particles are not inadvertently transferred to a printing paper, such that blank image areas spattered with unintentionally transferred toner particles are minimized.

    摘要: An apparatus is provided for supporting a shift lever for a transmission the shift lever including a ball-like portion which is on the shift lever and has spherical surfaces of a fixed curvature at least on a part of the lower and upper sides. A receiving surface has a concave spherical surface of nearly the same curvature as the lower spherical surface of the ball-like portion and is in contact with the lower spherical surface, and a retaining surface has a concave spherical surface in surface contact with the upper spherical surface of the ball-like portion and holds the ball-like portion between the concave spherical surface and the receiving surface. A retaining member is installed from above to cover the ball-like portion, and an elastic displacement section is projectingly formed on the lower side of the retaining member to enclose the upper part of the ball-like portion and is elastically deformable in the radial direction of the ball-like portion. The retaining surface is formed on a part of the elastic displacement section which faces the ball-like portion. The ball-like portion is held in between the receiving surface and the retaining surface with the elastic force of the elastic displacement section, and a frictional force based on the elastic force acts as the shift-lever operating load.

    摘要: A device for selectively lifting a multiplicity of needles which are mounted to an upstanding, rotatable cylinder for up and down sliding motion. Each needle has a shank with two butts formed in vertically spaced positions thereon, so that there are formed tow rows of such butts extending circumferentially of the cylinder. The upper one, for example, of the two rows of butts includes a group of butts that are longer than the other butts of the same row. Slidably supported adjacent the cylinder are a pair of cams which are independently moved, as by solenoids, toward and away from the cylinder and which have sloping cam surfaces for relatively sliding engagement with the respective rows of butts when the cams are thrusted toward the cylinder in rotation. The vertical distance between the sloping surfaces of the two cams is so determined in relation to that of the butts on each needle shank that when the upper cam is first moved toward the cylinder for lifting the needles having the longer butts by making relatively sliding contact therewith, the other cam can be subsequently moved toward the cylinder without being loaded by the lower butts of the needles being raised. Then, as the longer upper butts ride off the upper cam, the following needles will be raised as their lower butts ride onto the lower cam.
