A laminate comprises a gas barrier layer and an inorganic compound layer, the gas barrier layer being formed of a material that includes at least an oxygen atom, a carbon atom, and a silicon atom, the gas barrier layer having an oxygen atom content rate that gradually decreases from the surface of the gas barrier layer in the depth direction, and having a carbon atom content rate that gradually increases from the surface of the gas barrier layer in the depth direction. An electronic device member includes the laminate, and an electronic device includes the electronic device member. The laminate exhibits an excellent gas barrier capability and excellent transparency, and does not produce cracks (i.e., the gas barrier capability does not deteriorate) even when the laminate is folded. The laminate exhibits an excellent gas barrier capability and an excellent impact-absorbing capability even if an impact is applied from the outside.

A hoisting and lowering driving engagement multi-row chain is disclosed, in which bending of the connecting pins in the chain is suppressed to avoid fatigue failure. Additionally, the load carrying balance in the chain width direction is improved, and contact vibrations and contact noises generated between the chain and the hoisting and lowering sprockets are suppressed. Endurance of the bush in the chain is thereby improved. Bending of connecting pins is avoided by press-fitting bushes, through which connecting pins pass, into intermediate tooth plates. This also improves load carrying balance widthwise. Contact noises and vibrations between the bushes and sprockets are suppressed by providing bushes with a separate sprocket engagement portion having a larger diameter than the press-fitting portion of the bushes.

The invention provides a laminated glass and a method of producing the same. This laminated glass includes first and second transparent glass plates and an interlayer film interposed therebetween. This interlayer film has functional ultra-fine particles which have a particle diameter of up to 0.2 &mgr;m and are dispersed therein. Due to the incorporation of the ultra-fine particles thereinto, the interlayer film is provided with various additional functions such as heat insulation, ultraviolet ray absorption and the maintenance of a sufficient radio transmittance. Therefore, the laminated glass becomes suitable as an architectural or automotive laminated glass.

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.
