Abstract: PURPOSE: To prevent the rusting of a constituting instrument such as a switch- board and the like in a high temperature and humidity chamber by the mechanism wherein a compressed air producing, purifying and dehumidifying devices and the like are provided within a board of a dust preventing structure and the purified air is supplied into other board of the same structure and a part of air is circulated.  
     CONSTITUTION: In a boad of a dust preventing structure, a compressor 7, a freezer type air dryer 11, a filter 8, 9, 10, a vacuum valve 13, 14 and the like is provided and the dehumidified and purified predetermined pressure air (about 5mm H 2 O) is supplied from a feeding port 11 through an air passage opening 5 between walls to a switch-board 2, 3, 4 of a dust preventing structure and above-described air is circulated through a valve 6 to a board 1. The compressed air is prepared from outside air introduced from a filter 23, 24 and the circulating air. When the pressure in the switch-board 2, 3, 4 is reached to about 5mm H 2 O, the vacuum valve 14 stops  the supply of air and initiates the supply of air when lowered below a predetermined pressure. Accordingly, the rust generation at the switch-board is prevented.

Title: Magnetic head
Inventor: FUJIOKA YOSHIHARU
IPC: G11B5/187
Filed: 1982-07-30
Abstract: PURPOSE:To allow to contact a contact sliding surface of a magnetic recording medium to a magnetic recording medium stably by the negative pressure of an air flow, by providing an arrow-shaped groove which extends from the upstream side to the downstream side in its relative movement direction of the magnetic recording medium in an area of said contact sliding surface except head gap parts. CONSTITUTION:The groove 17 extending from the upstream side to the downstream side in the relative movement direction (shown by an arrow A in a figure) is provided in the contact sliding surface of the magnetic head for the magnetic recording medium except at gap parts 12 and 13. When the magnetic recording medium moves in contact with the contact sliding surface relatively as shown by the arrow A, an air flow is generated in the gap part formed by the groove 17 between the head body and magnetic recording medium to flow along the groove 17. Namely, the air flow flows in the groove 17 from the upstream side to the downstream side of the head. However, the air flow decrease in density gradually because the groove width of the groove 17 increases gradually, so a negative pressure is generated eventually.

Abstract: PURPOSE:To prevent defective fixing by arranging three points, centers of rotation of a driving roller and a driven roller and the center of oscillation of a holding lever, to form an obtuse angle triangle making the center of rotation of the driven roller an apex. CONSTITUTION:A heating roller 4, a pressure roller 5 and a holding lever 9 are so arranged that three points i.e. centers A, B of the two rollers 4, 5 and the center of oscillation C of the holding lever 9 form an obtuse angle triangle that makes the center of rotation B an apex, and so constituted that when the heating roller 4 is rotated, the pressure roller 5 is energized to move in the direction of biting, that is, the direction of rotation of contact of the two rollers 4, 5. Consequently, the vertical angle becomes close to two right angles and the distance between centers A, B of two rollers 4, 5 is shortened. Rollers 4, 5 come into contact with outer peripheral part etc. of the pressure roller 5 or heating roller 4 elastically deformed and specified pressure contacting force acts between rollers. Thus, a toner image on the recording paper is pressed, heated and fixed. When fixing action is completed and rotation of the heating roller is stopped, pressure contacting force between rollers 4, 5 is lowered to original condition.

Then, in the region wherein the Al composition ratio is made from 0.3 to 0, 20 seconds are made one time unit and at first, the shutter of an Al cell is opened for 19 seconds in 20 seconds, next for 18 seconds in the 20 seconds and in this way, repeated to gradually reduce the Al composition in a crystal film grown in 20 seconds and simultaneously, the temperature of the Al cell is lowered by cooling and the vapor pressure of Al is also reduced. A thin film which has the thickness of approx. 50 nm and a gentle gradient Al composition ratio is formed by repeating the process for 20 seconds 12 times.
