Title: Manufacture of rotary cylinder
Inventor: NAKAJIMA HIROSHI
IPC: G11B15/61
Filed: 1988-01-06
Abstract: PURPOSE:To reduce the breakdown of a magnetic tape by forming a low friction layer thinner after executing puffing on the edge part of the head fitting window of a rotary cylinder base metal as well as cut-forming the low friction layer of the outer peripheral face of the rotary cylinder base metal in specified diameter and executing puffing once again. CONSTITUTION:After forming the outer peripheral face of the base metal 3 of a rotary cylinder by cutting it slightly smaller than the specified diameter a low friction layer is formed so that the outer peripheral face of this rotary cylinder base metal 3 becomes slightly larger than the specified diameter and the low friction layer of the rotary cylinder base metal 3 outer peripheral face is further cut in the specified diameter. The edge part 6 of the head fitting window of the rotary cylinder base metal 3 is subjected to puffing again by forming the low friction layer thinner after executing its puffing. The breakdown of a magnetic tape by the edge part 6 of the head fitting window can thus be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain a gas chromatograph in which mutual reference of a holding time between analyzed results of a plurality of devices is performed easily, by displaying the corrected holding time which is calculated on the basis of the value of the holding time in every analysis of one or a plurality of identical reference substances. SOLUTION: A gas chromatograph is provided with a computing part 8 which measures and computes a holding time of every peak as qualitative information and which contains an A/D converter and a computer. Then, by using a device to be used as a reference, e.g. a reference substance N, a component X to be measured, and a sample which contains methane M as a substance hardly interacting with a measuring column are analyzed. The relative holding time Tx =(tx -tm )/(tn -tm ) of the component X is found on the basis of a holding time tx , a holding time tn and a holding time tm . Regarding other devices under the same condition, the relative holding time is found in the same manner.  When the difference between the respective devices is within a prescribed range, the holding time of all components X to be measured is multiplied by a prescribed identical correction factor, and the holding time is corrected between the devices. When the difference is outside the prescribed range, a correction factor which is different for every component X to be measured is used. In addition, when the difference is large, the holding time is judged to be abnormal.

Abstract: PROBLEM TO BE SOLVED: To obtain a steel sheet having small surface roughness and excellent electromagnetic characteristic by using work rolls specified in the surface roughness in the first stand in the secondary cold-rolling and inclined polished work rolls having the specified surface roughness on and after the second stand. SOLUTION: In the first stand in the secondary cold-rolled process to the silicon steel hot-rolled sheet, oxide scale developed on the steel surface at the time of intermediate-annealing is easily peeled off and further higher friction coefficient is secured by using the work rolls having large surface roughness, such as 1.0-3.0 μm Ra. In one or more stands on the after the second stand, the inclined polished work rolls having 0.05-0.5 μm Ra are used. The enclosure of rolling oil into roll bite is prevented with this combination of rolls and the development of oil pit can be restrained. At the same time, the rolling with higher friction coefficient than that of the scratch rolls conventionally used, is executed. As an inhibitor component to the silicon, AlN, MnS, MnSe, etc., be used.

Abstract: PROBLEM TO BE SOLVED: To smoothly execute optical path length scanning over a long distance at a high speed, with a compact constitution. SOLUTION: A logarithmic helix mirror 1 is disposed rotatably around a spindle 2. The logarithmic helix mirror 1 is constituted by forming an outer contour 1-1 at the cross section perpendicular to the axial direction of the spindle 2 to a logarithmic helix shape having the center of the spindle 2 as an origin O and forming a tank (convex surface) 1-2 along the axial direction of the spindle 2 of the outer contour 1-1 formed to the logarithmic helix shape as a mirror finished surface. The mirror-finished surface 4-1 of a perpendicular reflection mirror 4 is directed towards the convex mirror finished surface 1-2 of the logarithmic helix mirror 1, so as to be perpendicular to a reflection optical axis 6. The light from an optical circuit or optical system, etc., is made incident along the optical axis 3.  In such a case, the reflection angle of the incident light on the convex mirror finished surface 1-2 is kept constant at all times, without depending upon the rotating angle of the logarithmic helix mirror 1. As a result, the reflection direction is made invariable and the light may be returned to the incident direction while the distance until the incident light arrives at the convex mirror finished surface 1-2 is changed.
