Title: Magnetic recording and reproducing device
Inventor: FUSE KENJI
IPC: G11B15/675
Filed: 1988-12-01
Abstract: PURPOSE:To attain recording and reproduction with respect to a cassette different in a system by providing a means which performs switching and setting in the first position and the second position of a linear track head. CONSTITUTION:When a tape cassette 21 for a herical scan system is loaded, a magnetic tape 13 is pulled out from a first tape cassette 21 and loaded on a cylinder device. At that time, the linear track head 40 is set in the first posi tion where a hindrance for the pulling-out of the magnetic tape 13 does not exist from the first tape cassette 21 by a second means 42. When a second tape cassette 54 for a linear track system is loaded, the magnetic tape is not pulled out from the second tape cassette 54, and the linear track head 40 moves to the second position by a second means 42 and is abutted on the magnetic tape in the second tape cassette 54. Thus, recording and reproduction can be performed in the tape cassette for the linear track system using a fixed head in a magnetic recording and reproducing device by the herical scan system.

Title: High speed re-closing earth switch device
Inventor: SAIDA TOSHIYUKI
IPC: H01H33/91
Filed: 1992-11-12
Abstract: PURPOSE:To break certainly the induction current which does not form any current zero point by protruding an arc electrode from a stationary contacting piece which is in direct coupling with a main circuit conductor, and sending a gas in a puffer chamber blowing to the tip of a movable contacting piece. CONSTITUTION:When pole opening proceeds, an arc 20 moves toward an arc electrode 21 positioned nearer geometrically than a stationary contacting piece 13, and part of the current flows to the arc electrode 21. Arcs 24 are generated between it 21 and a movable contacting piece 17, and finally all current substantially transfers to the arc electrode 21. The current path follows from a conductor 8, to a resistor 22, the arc electrode 21, arcs 24, the movable contacting piece 17, and a grounding terminal part. Thus generates the condition that the resistor 22 is automatically inserted in a breaking current circuit serially. The gas compressed in a puffer chamber 25 is passed through an exhaust hole 26 and released from the tip of the movable contacting piece 17 to blow to the arcs 24. As the separating distance of the two contacting pieces 13, 17 has become sufficiently large, the arcs 24 go out certainly and the breaking is completed.

Title: Image forming method
Inventor: EGUCHI GAKUO
IPC: B41M5/00
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent a printed image from becoming discolored without deteriorating transparency by applying a transparent liquid containing chitosan or the salts of organic and inorganic acids of chitosan to the surface of a recording medium containing an artificial boehmite before or/and after the formation of an image, in an ink jet method. SOLUTION: Chitosan salts are cited as salts obtained from an inorganic and an organic acid. The preferable viscosity of a transparent liquid is 10,000-100,000cps. To limit the viscosity of the transparent liquid within this range, it is preferable to use the chitosan with a molecular weight of 300,000 or less, and also is preferable to limit the amount of the chitosan contained in the transparent liquid within the range of 0.1-10wt.% for the total amount of the transparent liquid. A solvent should be of such a type that it is chemically stable and a vapor pressure is low and the chitosan compound is smoothly soluble and further, it is the same as a solvent used in a water soluble dye ink.  For the timing of applying the transparent liquid and the ink, it is preferable to apply them after the interlocking of the chitosan in the earlier applied transparent liquid or the dye in the ink with a recording medium.

Title: Vibro-isolating bush
Inventor: HATANO KATSUYA
IPC: F16F15/08
Filed: 1992-10-15
Abstract: PURPOSE:To reconsile control stability and cushionability by installing an insert and a vibrationproof rubber body in space between an inner cylinder and an outer cylinder, and forming the central part of an inner cylinder outer circumferential surface into a spherical convex and an insert inner circumferential surface into a spherical concave along the convex, respectively. CONSTITUTION:An inner cylinder 2 is installed in an outer cylinder 2, while an outer circumferential surface 11a of a bulge part 11 at the central part is formed into a spherical convex, and a ringlike insert 3 being well in slidability is installed in space between the outer circumferential surface 11 a and an inner circumferential surface of the outer cylinder 2, and the outer circumferential surface 3b is formed into a plane in contact with the inner circumferential surface of the outer cylinder 2, while the inner circumferential surface 3a into a spherical concave along the outer circumferential surface 11a, respectively, and two vibrationproof rubber bodies 4A, 4B are inserted into space between both the openings of the outer cylinder 2 and an inner cylinder 1. When a shaft straight directional vibration is inputted, the bulge part 11 comes into contact with the outer cylinder 2 via the insert 3, maintaining the rigidity of a vibro-isolating bush, and control stability is securable. When the axial vibration is inputted, the insert 3 slides on the inner circumferential surface of the outer cylinder 2 in a state of being engaged with the bulge part 11, whereby a spring constant of the vibro- isolating bush becomes lessened by each deformation of the vibrationproof rubber bodies 4A, 4B, so good cushionability is thus securable.

Abstract: PURPOSE:To perform a proper optical scanning by storing correction information corresponding to optical scanning intensity irregularity information and controlling the light output of a light source according to the stored correction information when actual optical scanning is performed so that the irregularity in optical scanning intensity is corrected. CONSTITUTION:A cylindrical lens 28 closest to a surface to be scanned on the optical path of an optical system for scanning is shifted or slanted slightly in a direction crossing its generating line orthogonally to reflect a part of scanning light by the surface of the cylindrical lens 28. Further, a photodetector 40 is arranged on the output terminal side of an optical fiber to detect and convert a part of the reflected scanning light into an electric signal at respective input terminal positions of the optical fiber 36, and a reference optical scan is made by using light from a light source 14 which performs light emission with specific intensity. At this time, the optical scanning intensity information is generated from the light intensity of light-reception of each optical fiber 36 and the correction information corresponding to said information is stored and when an actual optical scan is made, the light output of the light source 14 is controlled according to the stored correction information so that the irregularity in optical scanning intensity is corrected. Thus, an excellent optical scan is attained.

Title: Method and circuit for controlling slew rate of motor coil
Inventor: MAGGIO KENNETH J
IPC: H02P6/06
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent a control circuit from being broken without increasing costs, complexity, and power consumption, by controlling a coil current of a stator coil winding of a multi-phase DC motor, and eliminating or reducing current and voltage spikes being generated during commutation. SOLUTION: A stator coil winding 10 of a brushless DC motor performs Y-type connection and successively connect edge parts VA, VB, and VC of a coil A 14, a coil B 16, and a coil C 18 of a three-phase coil winding to a high- voltage side driver or a low-voltage side driver. Then, current flows from the coil A 14 to the coil C 18 after a high-voltage side commutation. And then, current flows from the coil A 14 to the coil B 16 due to a low-voltage side commutation. In this case, the low-voltage side commutation performs control so that the current of the coil B 16 increases from zero to a constant level as the current of the coil C 18 decreases to zero. Also, the high-voltage side commutation performs control so that the current at the coil A 14 decreases to zero and at the same time the current of the coil C 18 increases to a steady level from zero.
