摘要:
The object of the invention is to prevent interference fringes of images and allow precise measurement of the thickness of a layer by the optical interferometry by limiting the surface roughness of a conductive substrate. The surface roughness of the conductive substrate provided in an electrophotographic photoreceptor is such that the maximum peak-to-valley roughness height (Ry)=0.8 to 1.4 μm, the centerline average roughness (Ra)=0.10 to 0.15 μm, the ten-point average roughness (Rz)=0.7 to 1.3 μm, the average peak-to-peak distance (Sm)=5 to 30 μm, and the peak count Pc=60 to 100. In such an electrophotographic photoreceptor, light for exposure can be scattered to an appropriate extent, so that interference fringes can be prevented, and an interference pattern is formed during measurement of the thickness of the photosensitive layer by the optical interferometry so that the thickness of the layer can be measured with a high precision.

摘要:
Disclosed is a heat-storage device provided with a supply pipe, a discharge pipe, and a heat-storage container that contains a heat-storage material. A heat-storage material layer comprising said heat-storage material is formed in the bottom of the heat-storage container. The supply pipe supplies a heat-carrying oil, which has a lower specific gravity than the heat-storage material, from outside the heat-storage container to the inside of the heat-storage material layer. The discharge pipe discharges the heat-carrying oil, which had been supplied to the inside of the heat-storage material layer, to the outside of the heat-storage container. The heat-storage device is also provided with a plurality of metal plates (members inside the heat-storage material layer) arranged vertically inside the heat-storage material layer. A metal plate is also disposed such that the upper end thereof is at a height greater than or equal to the vicinity of the upper surface level (L) of the heat-storage material layer. The disclosed heat-storage device is better than conventional heat-storage devices at preventing the heat-storage material from escaping the heat-storage container.
