Title: Lubricating method for pinch roll
Inventor: NISHI TOMOO
IPC: B21B39/08
Filed: 1979-03-29
Abstract: PURPOSE:To prevent generation of the seizure and abrasion of the pinch roll at the position contacting the strip edge, and to improve the durability of the pinch roll, by feeding the lubricant oil to the position contacting the strip edge on the outer surface of the pinch roll. CONSTITUTION:Under the condition that the locating interval of the oil sprays 4, 4, on both sides of the pinch roll is adjusted correspondingly to breadth of the strip A being carried by upper and lower pinch rolls 2, 3, the lubricant oil is applied to the outer surface of the pinch 2 at the position contacting the strip edge, at the same time as the travel of the strip A. By thus applying the lubricant oil, the part contacting the strip edge on both sides of the upper pinch roll 2, is made extremely slippery against the strip A, so that generation of the friction between the strip edge and the upper pinch roll 2 is prevented more thoroughly as compared with the strip's middle part. As a result, the generation of seizure and abrasion of the pinch roll at the position corresponding to both side edges of the strip A can be prevented without hindering the carrying function of the upper and lower pinch rolls 2, 3.

Title: Accessing method for optical disk device
Inventor: ONO KAZUHIKO
IPC: G11B7/004
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To move an optical pick-up to a target position at a high speed, by moving an objective lens so as to focus on a target layer when a recording layer of target information differs, and then calculating the distance between two physical positions, that is, the current position and the target position. SOLUTION: First, the position of an optical pick-up for reading current position information recording on a disk is checked. Then, it is judged whether the recording position of target information is equal to the current recording layer. When the recording position of target information is not equal to the current recording layer, an objective lens is moved in a direction perpendicular to the disk so as to focus on the target layer. Then, the current position of the optical pick-up is checked. The current position and the target position are converted to physical positions on the disk, and the distance between the relative two points is calculated. Thus, the optical pick-up may be moved to the target position at a high speed without reading the position information recorded on the disk during moving.  After the movement, the pick-up is caused to access the target information recording position while the position information recorded on the disk is checked. Thus, high-speed access is easily carried out.

Title: Sinter operation control
Inventor: TASHIRO KIYOSHI
IPC: C22B1/16
Filed: 1978-04-05
Abstract: PURPOSE: In sintering raw material, fine granules less than 1 mm is controlled in acidity, whereby the reduction strength and sintered ore and NO x  generation are controlled to a desired value heretofore unattainable.  
     CONSTITUTION: It has been found that the acidity (CaO/SiO) of sintering raw material affects sintered reduction strength and NO x  generation as shown in the figure, in which the reduction strength indicates the resistance against pulverization in a reducing atomosphere at 500 to 600°C. In sintering operation, NO x  generation in exhaust gas and reduction strength of product are first observed, then the curves in the figure are used to shift these values to a desired value. For example, if NO x  generation is too high, the acidity in part of less than 1mm in the raw sintering ore is incresed. If the reduction strength is too low, the acidity in part of less than 1mm in the raw material is reduced.
