Title: Aluminum and aluminum alloy plate for fluorocarbon resin coating
Inventor: SASAKI YASUNORI
IPC: E04C2/26
Filed: 1985-02-14
Abstract: PURPOSE:To improve coated film quality and productivity by forming a rough surface on which the number of crests having a specific height is not less than the necessary number per specified measuring length using a roughened roller. CONSTITUTION:Al and Al alloy plates for fluorocarbon resin coating are rolled by a roller whose surface is roughened. In one of the rolling direction and the orthogonal direction to the rolling direction at least, the maximum height of crests per measuring length of 25.4mm is in a range of 2.5-3.5mum and crests are made so that the number of crests whose height is not less than 1.27mum is 25 or more per measuring length of 25.4mm. The number of crest is desirable to be not more than about 200 because of the transferring capacity of the roughened roller.

Title: Temperature detetor for organic photoreceptor drum
Inventor: KANAZAWA YASUTO
IPC: G01K13/08
Filed: 1995-01-24
Abstract: PURPOSE: To accurately control temperature by accurately detecting the surface temperature of an organic photoreceptor body drum, and to prevent the photoreceptor body drum from being damaged by constituting an insulation film of a polyethylene having a molecular weight equal to or more than a specific value. CONSTITUTION: After a heat-sensitive element 5 is mounted on a retaining body, the entire surface for mounting the element of a heat-sensitive element- retaining body is covered with an insulation film 6. Polyethylene with a molecular weight of 10<6> or higher is used as a constituting material of the film 6. Since the polyethylene has a small surface resistivity of approximately 10<13> Ω in an electrical insulating material, the adhesion of toner owing to electrification can be effectively prevented. Polyethylene with a molecular weight of 10<6> or higher is called ultra-high-molecular weight polyethylene, and has a small coefficient of friction of approximately 0.15 and is excellent in self-lubrication property and wear resistance, thus semi-permanently preventing the wear damage of the film.  Polyethylene with a molecular weight of 10<6> or higher includes ultra-high-molecular weight polyethylene and ultra-high-molecular weight polyethylene tape.

Title: Optical drawing apparatus
Inventor: KOMATA KIMIO
IPC: G03F1/88
Filed: 1987-02-10
Abstract: PURPOSE:To provide an exposure control function and to prepare a spot pattern by a simple method without regulating the quantity of light according to the thickness of a ruled line and without regulating a width or providing a filter, by spirally arranging light impervious or pervious windows in a predetermined circular region. CONSTITUTION:A spot pattern 41 is constituted by spirally arranging a large number of dots 42 as light pervious windows. In a spiral case, when a spiral is cut at the angles equal from the center, the cut segments become long toward the outer periphery. Therefore, when the pitch P between the dots is fixed, the dots are not radially overlapped, and the inside dots and outside dots are arranged so that the positions thereof are slightly shifted. When this pattern 41 is irradiated with light, the light passes from the light pervious dot parts and the number of the obtained light spots correspond to the number of the dots. Therefore, when the dots are spirally distributed with respect to the number and size corresponding to the diameter of a circle, exposure amount can be kept constant regardless of the thickness of the ruled line.
