IPC: G11B17/043
Filed: 1988-12-15
Abstract: PURPOSE:To attain miniaturization, thinning, and light weight by applying brake on the movement of a cassette when it is inserted and ejected by a first elastic member always functioning in a direction to close an aperture part against a shutter, and a second elastic member functioning in the direction to close the shutter only when the inserting operation and ejecting operation of the cassette are performed. CONSTITUTION:The first elastic member 125 which always functions in the direction to close the aperture part against the shutter 122, and the second elastic member 123 which function in the direction to close the shutter only when the inserting operation and ejecting operation of the cassette 150 are performed are provided. And the brake is applied on the movement of the cassette 150 when it is inserted and ejected by the first and second elastic members 125 and 123 via the shutter 122. Therefore, it is not required to attach a cassette braking mechanism at a disk ejecting mechanism, and the disk ejecting mechanism can be formed with the one with simple structure and not taking much space. In such a way, the miniaturization, the thinning, and the light weight of a device can be attained.

Title: Orientation processing method for magnetic field
Inventor: OGISU KENJI
IPC: G11B5/845
Filed: 1986-12-27
Abstract: PURPOSE:To perform a superior perpendicular orientation processing, by arranging magnets at both sides so that the same polarity of them are confronted with each other for the magnetic plane of a coating type magnetic recording medium using acicular magnetic powder, and impressing a rotary alternate magnetic field almost in parallel with the magnetic plane. CONSTITUTION:The magnets 2 and 3 are arranged so that the magnetic poles 2a and 3a, and 2b and 3b can be confronted with each other interposing the medium, and the AC current is impressed on a coil 4 so as to confront the magnetic poles with the same polarity. Therefore, the alternate magnetic fields are generated between the magnetic poles 2a and 2b, and between the 3a and 3b. And the magnetic field generated between the magnetic poles are compressed mutually, then, they become almost parallel magnetic fields in an area in the inside of the magnetic pole. Now, when the medium is traveled between the magnets 2 and 3, a magnetic field orientation processing is applied on a magnetic coating film coated on the medium in a perpendicular direction. In such way, it is possible to perform the superior perpendicular orientation processing without generating the turbulence of orientation or deterioration in surface property.

Title: Steering unit for vehicle
Inventor: NISHI YUTAKA
IPC: B62D117/00
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a steering unit for a vehicle to improve the deflection suppression performance against disturbances acted on the vehicle such as a crosswind, without losing the information on the road condition, as well as to enable the setting of the correct steering force in normal turn. SOLUTION: For the ratio α, the steering reaction torque against the overall steering torque, the upper limit αmax and the lower limit αmin are determined. So, the lower limit αmin at which the steering holding force is ensured to a certain extent and the information on the road condition can be detected sensitively. Furthermore, determination of the upper limit αmax at a relatively low level at which steering force setting is easily made makes it possible that correct steering force and vehicle behavior suppression force under the effect of disturbances are both made available throughout the entire running speed range.

Title: Seat for vehicle
Inventor: MARUTA TSUTOMU
IPC: B60N2/20
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent backward torsion caused by an excessive load on a seat back, by installing a stopper mechanism at a circular movement support portion of a seat cushion and the seat back restraining located on the compartment inner side that restricts the backward circular movement while allowing the forward circular movement of the seat back. SOLUTION: In this seat, the circular movement support portion of cushion and back frames located on the compartment inner side is integrally equipped with a stopper mechanism for the seat back 10b. When an excessive load is applied on the seat back 10b from the front so as to move it circularly backward, the fitting pin is received and supported by a small projection of the lower arm. Thus, the backward circular movement of the seat back 10b is restrained. In this received state, the bonding strength of the seat back 10b to a seat cushion 10a is high enough to efficiently disperse the excess load acting on the seat back 10b to the seat cushion 10a. As a result, the risk of backward torsion of the seat back 10b due to the excess load is eliminated.

Filed: 1987-12-16
Abstract: PURPOSE:To realize high speed, miniaturization and cost reduction by connecting a printing chip to the tip of a superconducting member, suspending a printing member on a coil so that the member is retractable, and installing a means to return a moved printing member from an initial position on a printing head. CONSTITUTION:A printing member 22 which is not energized during non-printing but is energized by means of a return spring 23 is positioned by engagement between a flange 28 and a support member 26. When printing is performed, the coil 21 is energized for a specified period of time. A magnetic flux generates in the coil by the energization. In the meantime, a magnetic flux which cancels the magnetic flux generates in a superconducting member 22, and therefore, a drive force P to move the printing member 22 generates in said member, so that it moves from an initial position toward the right hand resisting the energization force of a return spring 23 to perform printing with a printing chip 25. If the energization of the coil 21 is discontinued, each magnetic flux disappears, and the printing member 22 is energized by the return spring 23, returning to an initial position.

Title: Method of dip-soldering of flat package ic
Inventor: SHINDO TAKESHI
IPC: H05K3/34
Filed: 1990-11-20
Abstract: PURPOSE:To prevent a soldering bridge between IC-lead terminals from occurring by a method wherein a solder-pulling dummy terminal is provided near the outermost lead terminal of the flat package IC. CONSTITUTION:A printed circuit board 1 is moved in the direction of the arrow A on a flowing solder 7.
