Title: Fly-back line erasing circuit for cathode ray tube
Inventor: KAWAMURA KEIICHI
IPC: H04N3/24
Filed: 1987-07-29
Abstract: PURPOSE:To make proper and easy a fly-back line erasure based on the input of a blanking pulse by providing a switching circuit to change the division ratio of voltage divided circuit in accordance with the impressing of the blanking pulse so that an electric beam may not be discharged from the cathode of a cathode ray tube at the time of the generation of the blanking pulse. CONSTITUTION:In a condition in which the blanking pulse is not inputted to a transistor (TR)3, since a TR 2 is in an OFF-condition, a first grid G1 of a CRT is held at a prescribed bias voltage. Next, when the blanking pulse is inputted to the base of the TR 3, the TR 3 goes to an ON-condition, and its collector voltage V5 is reduced. A base voltage V4 of the TR 2 goes to a negative voltage, and sets the TR 2 to the ON-condition. As this result, a bias voltage V2 to the first grid G1 is increased to a negative direction, held at the cut-off voltage of the CRT or below, and a back-line erasing action can be attained stably and without fail.

Title: Magnetic recording medium
Inventor: GOMI KENICHI
IPC: G11B5/64
Filed: 1988-07-29
Abstract: PURPOSE:To obtain the medium of high quality free from cracks or exfoliation in its hardened surface layer by depositing layers selected from metal oxides, metal borides, metal nitrides and metal carbides to form a film on a nonmagnetic metal layer provided on a nonmagnetic substrate. CONSTITUTION:When an Al alloy is used for the substrate 1, for example, the nonmagnetic metal layer 2 is provided thereon and then layers which at least contain metal, selected from metal oxides, borides, nitrides and carbides are formed. The metal concentration in the metal compound layers is continuously varied along with the film thickness. Thereby, the adhesion strength between the Al substrate 1 and the surface layer 6 is increased and the coefficient of thermal expansion varies gradually from the substrate 1 to the surface layer 6. Thus, thermal deformation of the substrate 1 decreases and the obtained medium has high quality and is suitable for high density magnetic recording.

Title: Feed drive device
Inventor: SATO KYUICHI
IPC: F16H25/24
Filed: 1994-08-10
Abstract: PURPOSE:To prevent application of excessive compressive force to a bearing and generation of radial clearance. CONSTITUTION:Pretension is supplied to a ball screw 8 by means of a nut 10. When the pretension is eliminated through extention of the ball screw 8 due to thermal expansion, compressive force is applied to bearings 4, 7. A disc spring 24 is flexured and receives the compressive force, so that excessive compressive force is not applied to the bearings. A compression ring 27 pushes an outer ring 6b of the bearing 6 to the side of the disc spring 24, so that radial clearance is not generated between an inner ring 6a and the outer ring 6b.

IPC: B41J11/20
Filed: 1989-07-20
Abstract: PURPOSE:To enable a jammed paper to be taken out easily by attaching a support frame for a flat platen to a support frame of a main printer system in freely closing manner and holding paper tightly between the flat platen and the main printer system with the flat platen installed in such a manner that it rotates laterally in a paper transport direction and also rotates to the right and left in a paper width direction. CONSTITUTION:An upper unit 16 has a support frame 15 supported axially on a support frame 11 of a lower unit 12 by a pivot 17 in freely rotatable manner, and is freely closed to the lower unit 12. Consequently, if an upper positioning table 28 partly comes in contact with a lower positioning table 25 by inclination of a printing head 21 in a printing direction, or partly comes in contact with the lower positioning table 25 in a direction crossing a printing direction at right angles, an arm 1 rotates laterally in a transport direction and to the right and left in a paper width direction with pins 32, 34 as pivots by squeezing in the upper positioning table 28. Thus fine adjustment of both units is performed. Consequently, a jammed paper can easily be taken out.

Title: Method of removing molten iron from rockwool electric furnace
Inventor: MUTSUMACHI KENZOU
IPC: C03B5/26
Filed: 1988-07-28
Abstract: PURPOSE:To protect the bottom of the furnace by inclining the bottom of the furnace such that it becomes lower from the molten iron removal opening toward the opposite side for the purpose that only the molten iron above the level of the molten iron removal opening is discharged through said opening. CONSTITUTION:When the molten iron B is to be removed, the whole furnace is tilted by means of a tilting cylinder 8 to lift the molten iron removal opening 4 and incline the bottom of the furnace such that it becomes lower from the molten iron removal opening 4 toward the opposite side. Then, the molten iron removal opening 4 is opened by removing the closure lid 5 to discharge the molten iron B from the furnace bottom through said opening 4. As the molten iron B is discharged, that part of the molten iron B which is above the level of the molten iron removal opening 4, but the rest of the molten iron below that level stays in the furnace. On account of the remaining molten iron on the furnace bottom, the furnace bottom is protected from the rockwool material getting in contact with the carbon lining on the furnace bottom.

Filed: 1990-07-17
Abstract: PURPOSE:To appropriately detect an abnormal state of deviating from a proper irradiating state of a light beam spot by using an irradiating state detecting result and a reference value for showing a range of the proper state changeably set in advance in corresponding to a medium. CONSTITUTION:An amplitude value of an information reproducing signal 9 is observed by a microcomputer 10. Then, an offset signal from an offset impressing block 7 is impressed upon an adding point 11. Values of (b) and (c) of a focusing error signal obtained here are set as error detecting thresholds (t) of an error detecting block 6. In a similar manner, error detecting thresholds are set in a tracking servo circuit. When focusing errors are increased due to something like disturbance and external impact, etc., to exceed the error detecting thresholds, it is decided as the abnormal situation to be dealt with. Thus, by setting the error detecting thresholds for detecting the abnormal situation in corresponding to the disk to be used, the detection of the improperly abnormal situation is prevented.

Abstract: PURPOSE:To reduce the deterioration of symmetricalness of a record/ reproduction waveform that is caused by the fact that an erasion magnetic field is picked up by a back core which forms a closed magnetic circuit for record/reproduction, by attaching the back core to a back end face of a record/ reproduction core at the side opposite to the rubbing surface to a recording medium. CONSTITUTION:A square bar-shaped back core 2 the same in thickness as a record/reproduction core 1 is fixed to a back end face 11 of the core 1 via an adhesive or a spring, etc. These cores 1 and 2 form a closed magnetic circuit for record/reproduction. While the erasion cores 3 forming erasion gaps 6 are set at the places near a record/reproduction gap 5 at both sides of the core 1 as if they were set orthogonal to the head 1. The inner sides of both ends of a U-shaped erasion yoke core 4 are welded to the faces at both ends of the core 3 as if they enclosed an approximately T-shaped bar of the core 1 by means of an adhesive. Then a front panel is attached to both side faces of the front part of the core 1 by an adhesive, etc. so that the front panel of a nonmagnetic substance is positioned on the same surfase as the front end face of the core 1. Thus a magnetic head is completed.
