Inventor: KATAHASHI HISASHI
IPC: C23C14/12
Filed: 1984-10-19
Abstract: PURPOSE:To form 'Permalloy(R)' film having a desired anisotropic magnetic field simply, by using gaseous mixture of Ar and O2 as sputtering gas, and regulating the partial pressure ratio thereof to a specified range, in DC opposed sputtering method. CONSTITUTION:In 'Permalloy(R)' film formation by DC opposed target sputtering method, gaseous mixture of Ar and O2 is used for sputtering gas and partial pressure ratio of O2 to Ar therein is regulated to 0.01-0.1 range. Negative voltage is impressed to a target 1 under existence of the gaseous mixture to generate plasma between the targets 1, 1, and 'Permalloy(R)' film is formed on a substrate 2. Thereat, since the targets 1 are arranged symmetrically to the substrate 2, film thickness distribution is made small, and the ratio of partial pressure of O2 to that of Ar is varied in 0.01-0.1 range. Thereby, 'Permalloy(R)' film in which size of anisotropic magnetic field is controlled is obtd.

Title: Method and device for tapering optical fiber
Inventor: MIMURA MICHIHIKO
IPC: G02B6/287
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To permit rapid processing of a stable shape and to reduce the cost of optical parts by shortening of processing time and an improvement in a yield by forming an AC arc discharge region within a groove of an insulating block and stretching an optical fiber in this groove. SOLUTION: Tapered parts 6b are formed at the optical fiber 6 by stretching the optical fiber 6 while heating the optical fiber with a heating means.

Title: Impact type serial printer
Inventor: KAMITSUBARA KINJI
IPC: B41J25/304
Filed: 1989-08-24
Abstract: PURPOSE:To prevent paper from becoming contaminated due to its contact with an ink ribbon by enlarging the gap between the ink ribbon and the paper based on recognition of a type. CONSTITUTION:A control part 1 controls the whole printer and at the same time, always interprets whether print is present at present moment. If printing is underway, the control part 1 connects a signal to a printing head regression mechanism drive part 2 so that a printing head 4 is controlled to be set to a normal printing position. The printing head retract mechanism drive part 2, receiving the signal, drives a printing head retract mechanism 3 to be fixed to a normal printing position. Next, if the control part 1 interprets that printing is not underway, the control part connects a signal to the printing head mechanism drive part 2 so that the printing head is moved backward. In addition, the printing head mechanism drive part 2 moves the printing head backward and enlarges the gap between an ink ribbon and printing paper. Therefore, printing paper is not contaminated by contact with an ink ribbon 5, even when the paper is fed laterally without printing action.

Abstract: PURPOSE:To make the movement of a hood as smooth as possible by unifying the joint of the first and the second guide devices almost concentrically with a position regulating device when a board member is moved from the moving position to the storing position. CONSTITUTION:When a board member 20 on which a hood is folded and loaded is moved from the moving position to the storing position, a gearing pin 98 for locking operation is moved to an intermediate position to set the hood to the opening position. As a result, the pin 98 is contacted again to the third projection 74, and the first lever 66 is positioned to the gearing position again. Consequently, at the time when the board member 20 is restored to the storing position from the moving position, the relative position in the up and down direction and in the rail axial direction between the first rail 51 and the second rail 52 is set securely at the specific position by the operation of the locking mechanism 60, even though the alignment of the first rail 51 and the second rail 52 of the guide rail 50 is not completed adequately.
