Title: Method and device for assembling magnetic head
Inventor: ODA KAZUO
IPC: G11B5/60
Filed: 1989-06-21
Abstract: PURPOSE:To allow a core to be positioned and fixed by means of a shim by inserting the core which is attracted by magnetic force into a long hole via a V-groove, aligning this long hole into the groove of the slider, inserting the core into the groove, and inserting the V-shaped shim into the spacing between the core and the groove. CONSTITUTION:The position of the core 4 attracted by the magnetic force is regulated by the V-groove. The attraction is released when the core 4 is inserted into the long hole 39 communicating with the V-groove 38. The core 4 is inserted into the groove 3 of the slider 2 when the long hole 39 is moved. The approximately V-shaped shim 5 is inserted into the groove 3 while the shim is brought into sliding contact with the core 4 and the core 4 is fixed to the slider 2 by the elastic force of the shim 5. The core 4 and the shim 5 are smoothly inserted into the groove of the slider 2 in this way. The method for assembling the magnetic head in which the core 4 is securely fixed by the shim 5 is thus obtd.

Title: Light irradiating method
Inventor: GOTO YOSHINORI
IPC: B05C9/14
Filed: 1984-07-31
Abstract: PURPOSE:To permit uniform irradiation of surface of long-sized articles having different outside diameters by allowing the axial centers of an article to be irradiated and irradiating part by moving a furnance body veritically depending on the outside diameter of the aritcle to be irradiated, and executing lighting with appropriate distance for an article having a small outside diameter. CONSTITUTION:When an article W to be irradiated such as metallic pipe, coated with a photosetting paint passes through a light irradiating zone, a furnace body 4 is moved vertically to a degree in accordance with the ouside diameter of the article until the axial center C of the article W to be irradiated coincides to the axial center C of the light irradiating part. Accordingly, the distance from each lamp 5 to the surface of the article W to be irradiated becomes always same, so uniform irradiation is accomplished. Since large irradiating quantity is required for an article having a large outside diameter, the whole lamps 5 are lit, but if the outside diameter is small, the distance of lighting is increased, and pairs of the lamp 5b and mirror 6 are moved toward the axial center C. By this method, uniform irradiation is realized with optimum power consumption.

Filed: 1979-12-08
Abstract: PURPOSE: To eliminate the staying of air bybbles generated in a communicating oil channel on the occasion that one auxiliary oil reservoir is employed by arranging the master cylinder in an inclined manner.  
     CONSTITUTION: Within the main body 1 of a cylinder are provided the 1st piston 3 and the 2nd piston 3' which partition the 1st oil pressure chamber 4 and the 2nd oil pressure chamber 4' respectively, and thus the tandem-type master cylinder is constituted. In the upper part of the main body 1 an oil tank R is provided and is communicated with the oil pressure chamber 4 through a bypass hole 10 and a supply hole 11, while being communicated with the oil pressure chamber 4' through an oil channel 13. Since the main body 1 of the cylinder is arranged in the inclined manner as a whole, the oil channel 13 is also inclined, and therefore, even when air bubbles are generated in the oil channel 13, they are guided and discharged into the oil tank R, not staying in the oil channel. Thus, normal operation of the master cylinder can be secured.

Abstract: PURPOSE:To prevent the miserasion of an ordinary tape, by opening a cassette holder with a push of an ejection button via a rotary member having two function parts, and at the same time, switching a function changeover switch to the ordinary tape side. CONSTITUTION:A rotary member 13 is attached rotatably to a shaft 15 of a chassis 6, and function parts 13a and 13b touch a function changeover switch 11 and a mobile member 16 respectively. The cam part of a cam plate 12 of an ejection button 10 touches a projected part 14. With a push of the button 10, the member 13 is turned counterclockwise at the cam part.

Abstract: PROBLEM TO BE SOLVED: To facilitate quantitative determination of surface properties by irradiating the surface of an object with the light from a diffused light source having a shield mask thereby obtaining the information of reflected image including the dark field part caused by the shield mask. SOLUTION: The surface of an object (e.g. a glass) 3 is irradiated with the light from a white diffusion light source 1 having a shield mask 2 and the image of light reflected on the surface is picked up by means of an image pickup unit 5, e.g. a CCD camera, and fed to a processing unit 6. It is then corrected in order to eliminate the effect of illumination by other than the light source, blur of the optical system caused by the shield mask 2, etc. The dark field part of the reflected image caused by the shield mask 2 brings about a dark state of low brightness but an image of high brightness can be obtained even at the shielded part if the surface to be evaluated is roughened. Roughness on the surface of the object 3 is determined quantitatively based on the reflected image including the dark field part caused by the shield mask 2.

Title: Magnetic recording medium and its production
Inventor: KONDOU MAKI
IPC: G11B5/738
Filed: 1989-06-26
Abstract: PURPOSE:To obtain a medium having excellent sliding resistance against a magnetic head by using a chromium nitride (Cr2N) layer having high hardness or a mixture of Cr2N and CrN as a base layer. CONSTITUTION:The base layer 2 on a substrate 1 consists of a Cr2N layer having enough mechanical strength which protects the magnetic recording medium from damage caused by contact or collision of a magnetic head, or the base layer consists of a mixture layer of Cr2N and CrN. A CrN layer is not used because of its inferior bardness. After the base layer 2 is formed, there are formed an intermediated layer 3, magnetic layer 4 and protective layer 5, or further protective layer 6, for example, by physical vapor deposition (PVD) method such as sputtering. Thereby, the obtd. disk has enough surface flatness which can maintain a stable floating state of a head even when the head floats at small height from the disk. Thus, the medium has excellent sliding resistance to the magnetic head.

Title: Sheet feeder
Inventor: HAMADA TATSUO
IPC: B65H3/06
Filed: 1990-06-19
Abstract: PURPOSE:To prevent generation of accompanied rotation at a shaft in a sheet feeder of an electronic photographic machine by attaching a roller which is rotated in contact with a sheet, aside from a feeding roller, and by providing a frictional resistance applying means for giving a load to its rotation. CONSTITUTION:A feeding process of a sheet P is started in a stand-by state that a driving force from a motor is not transmitted to a shaft 3 because of no-load rotation of a one-rotation control clutch 12, and the shaft 3 is stopped. When a feeding signal is sent to a feeding solenoid 11, a claw part 11a of the solenoid is released and the driving force from the motor is transmitted to the shaft 3 through the one-rotation control clutch 12. A feeding roller 1 in the shape of a half moon fixed to the shaft 3 is rotated so as to feed the sheet P, which is separated one by one by a separating pad 4 and sent to a resist roller 8. After the feeding roller 1 makes one rotation, it is brought into the stand-by state again, while the sheet P is carried on interposed between a driven roller 2 and the separating pad 4, whereby accompanied rotation is prevented.
