Abstract: PURPOSE:To improve the picture quality by providing a back coating layer of specified surface roughness which contains carbon black of specified particle size, a filler of specified hardness, and polyurethane having secondary and/or tertiary hydroxide groups as the side chain on the opposite side of a nonmagnetic supporting body to the magnetic layer side. CONSTITUTION:The magnetic recording medium consists of a nonmagnetic supporting body 1, a magnetic layer 2 formed on the supporting body, and a back coating layer 3 provided on the back surface of the supporting body 1. The layer 3 contains a binder and a filler dispersed in the binder. The binder contains specified polyurethane, namely, such one containing secondary and/or tertiary hydroxide groups as at least the side chain. As for the filler to be incorporated with the carbon black of 10-70 mmu average particle size, such a material having >=3 Mohs' hardness is used. The surface roughness of the layer 3 is specified to <=0.026 Ra. After applying a magnetic coating material on the surface of a nonmagnetic supporting body, the coating film not dried is subjected to orienting treatment and surface smoothening treatment. Thereby, stable traveling property and excellent picture quality can be obtained with reduction of dropout.

Title: Reduction projection type exposure device
Inventor: SAKAMOTO SHINGO
IPC: G03F9/00
Filed: 1989-06-23
Abstract: PURPOSE:To prevent the direct adhesion of dust while also obviating the error of the detection of an origin due to fouling by covering the upper section of the origin mark of a coordinate system positioning a wafer stage, on which a semiconductor substrate is fixed, with a transparent substance in a reduction projection type exposure device transferring a pattern on a mask onto the semiconductor substrate through a reduction projection lens. CONSTITUTION:Structure in which a columnar transparent plate 3 having the same diameter as an origin mark base 2 is closely stuck to the upper sections of origin marks 1 formed by shaping stepped sections to the origin mark base 2 composed of quartz, etc., in order to prevent the fouling of dust, etc., is formed. Accordingly, the direct adhesion of dust onto the origin marks 1 is prevented while an adverse effect on the detection of an origin can be reduced remarkably because the height of the origin marks 1 and dust differs even when the fouling of dust, etc., attaches on the flat top face of the columnar transparent plate 3.

IPC: G06T1/00
Filed: 1990-06-20
Abstract: PURPOSE:To accelerate memory check by performing data check by a central processing unit after reducing data size by a graphic display controller capable of performing fast processing, etc. CONSTITUTION:'0' data is filled(fill) in a check area. Thence, the data is reduced and transferred as performing an OR arithmetic operation by the graphic display controller(GDC) 7. Reduced data is checked by a CPU 1. Since output shows '1' if even 'one 1' exists in input data in the OR arithmetic operation, it is judged that original data also show all '0's when the reduced data show all '0's. '1' data is filled in the check area. The data is reduced and transferred as performing an AND arithmetic operation by the GDC 7. The reduced data is checked by the CPU 1.

Title: Enclosed rotary compressor
Inventor: SHIMAMOTO YOSHIYUKI
IPC: F04C29/02
Filed: 1984-08-01
Abstract: PURPOSE:To prevent oil inside a compressor from reducing, by forming each interconnecting passage leding discharge gas into an axial direction of the compressor in a lower end plate and a cylinder body respectively, while interconnecting it to a conduction groove formed with the interconnecting passage in an upper end plate and opened in a radial direction of the compressor. CONSTITUTION:In this compressor, compressed gas enters a discharge space C, passing through each of interconnecting grooves 8b and 4a' formed in a compressor axial direction of a lower end plate 8 and a cylinder body 4, and collides with a wall surface of a conduction groove 11a opened in a compressor radial direction of an upper end plate 11, thus its flow varies. Therefore, this high temperature, high velocity compressed gas will not collide with stator winding 2a directly so that a lowering of reliability due to a temperature rise in the stator winding 2a is preventable. And, the compressed gas is made to collide with the wall surface of the conduction groove 11a whereby gas is separatable from lubricating oil, thus discharge of the lubricating oil to the outside of the compressor is reducible.
