Title: Grinding of magnetic head
Inventor: OKU TSUNEO
IPC: G11B5/53
Filed: 1990-11-13
Abstract: PURPOSE:To grind a work into a desired shape by a method wherein a tape forming guide is moved to a specified protrusion value of the work, a vacuum pump is started to stick a grinding tape on an internal surface of the guide by air-suction and then, a motor for driving the grinding tape is rotated. CONSTITUTION:Magnetic heads 13a and 13b yet to be worked to a work support plate 12 are mounted on a work support plate rotating shaft 10 and a work support plate rotation driving section is lifted to be combined with a work support plate support shaft 11. Then, tape forming guides 7a and 7b are moved to a position equivalent to a specified work protrusion value while vacuum pumps V and P are started to stick a grinding tape 2 on inner circumferential surfaces of the guides 7a and 7b by air-suction. When a motor for driving the grinding tape is rotated, the tape 2 is kept in contact with a magnetic tape sliding surface under a specified pressure. At the same time, a drive motor 10a starts a fast rotation as specified to repeat normal and reverse rotation for a specified time with a timer preset. The motor 10a is stopped and the work support plate is taken out. Thus, a series of operations are ended.

Filed: 1990-11-08
Abstract: PURPOSE:To obtain an organic photoreceptor prevented with the surface peeling, the rise of residual potential and the occurrence of black stripes by cleaning and roughening the surface of a photosensitive layer before forming a vacuum thin film on the surface of the organic photosensitive layer as a surface protective layer. CONSTITUTION:For the cleaning method of a photosensitive layer, the dipping method, shower method, and steam cleaning method may be applied, the dipping method is preferable, and it is sufficient to dip the photosensitive layer in a hexane solvent at 20 deg.C for about 60 sec in this cleaning method, for example. A mechanical rubbing means pressing and rubbing a fabric or a brush is used for the surface roughening method, and many buffs may be used for the buff rubbing treatment. A vacuum thin film is formed on the surface of the organic photosensitive layer as a surface protective layer after the cleaning process and the roughening treatment are completed. Such problems as the defective toner cleaning, the rise of residual potential due to repeated use, and the occurrence of black stripes caused by it are prevented.

Title: Detector for predetermined characteristic of object such as coin
Inventor: JIYOSEFU ERU REBASEERU
IPC: G01N21/84
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To accurately detect and identify an object (coin) consisting of a different metal by generating an electromagnetic field within a region with an electromagnetic speed sensor for detection when the object such as coil is located at a predetermined specific position. SOLUTION: A coin 10 where a center region 12 and a circumferential rim part 14 are formed by another metal is introduced into an automatic vending machine, reaches pot cores 20 and 22 of an electromagnetic sensor on a rail 16, and enters the space between openings 52 and 54, thus preventing light from a light source 44 of a photosensor from entering a photocell 46. When the coin 10 travels and exit the regions of the openings 52 and 54, light beams reach the cell 46 again, the outside or a rim part 14 of the coin 10 crosses the space between the coils 40 and 42 of the electromagnetic sensor at the position, thus causing a change in the electromagnetic field created by the coils 40 and 42 due to the electromagnetic characteristics of a constitution material.  By detecting the change, the type, dimension, and area of the material for constituting the coil 10 and the thickness of the coin 10 are detected. The same inspection can be executed when the coin 10 initially reaches a light path or interrupts the light path.

Title: Method for correcting gain of flow sensor
Inventor: ABE TAKESHI
IPC: G01F1/20
Filed: 1990-11-09
Abstract: PURPOSE:To correct a gain with high accuracy by increasing calibration frequency without lowering the accuracy of the automatic calibration function of sensitivity by renewing the gain on the basis of the average value of the gain estimated value at the time of correction and a plurality of the estimated values of the previous time.

Title: Thin film head for perpendicular magnetic recording
Inventor: TODA JUNZO
IPC: G11B5/11
Filed: 1987-12-02
Abstract: PURPOSE:To improve the recording and reproducing efficiency by constituting a protective film of a magnetic material and providing a superconductive film between the magnetic protective film and a main magnetic pole. CONSTITUTION:When a driving current flows to the thin film coil 24 of a head at a temperature lower than the critical temperature of a superconductive film 26, a main magnetic pole 25 is excited and a magnetic field is generated from its front end to perform magnetic recording. At this time, this magnetic field is shielded by the existence of the superconductive film 26 and is not leaked to a magnetic protective film 27, and therefore, the magnetic field is not generated from the magnetic protective film 27. The external leaked magnetic field from the side of a magnetic recording medium 11 is absorbed by the magnetic protective film 27, and this absorbed magnetic field has not an influence upon the main magnetic pole 25 by the existence of the superconductive film 26, and the medium is not demagnetized because concentration of the external leaked magnetic field to the main magnetic pole 25 is prevented. Thus, the recording efficiency is improved by the elimination of the leak of the magnetic field from the main magnetic pole to the magnetic protective film 27, and the reproducing efficiency is improved because the main magnetic pole 25 effectively absorbs the required magnetic flux recorded on a magnetic recording medium 11.
