Title: Magnetic head slider
Inventor: TOKUYAMA MIKIO
IPC: G11B5/60
Filed: 1990-04-16
Abstract: PURPOSE:To prevent a damage due to the contact between a slider and a magnetic disk by fitting the magnetic head so as to be protruded to the face of the magnetic disk from an end face of a floating slider and providing a moment of inertia interrupt means between the slider and the magnetic head. CONSTITUTION:A magnetic head 6 movable in the vertical direction with respect to a floating face 20 of a slider 1 is provided to the floating slider 1 through the forming of air film onto a magnetic disk 100 so that the magnetic head 6 is extended to a face of the magnetic disk 100 from the floating face 20 at the tip of a moving member 5. In this case, the mass of the slider is far heavier than that of the magnetic head. Thus, only the magnetic head is made close to the magnetic disk to allow a damage to be decreased even when the both are in contact with each other.

Title: Magnetic head cleaning tape and signal recording method to magnetic head cleaning tape
Inventor: MATSUBAYASHI YOSHITERU
IPC: G11B5/86
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To improve cost effectiveness and process ability without deteriorating the electromagnetic transformation characteristic while unnecessitating a magnetic head at the time of recording by bringing a cleaning tape having specified residual magnetic flux density, surface roughness and coercive force into contact with a mother tape having the magnetic layer provided with a specific coercive force and transferring thereto. SOLUTION: The cleaning tape is produced by forming the magnetic layer in such a manner that a magnetic coating material mixed and dispersed with an abrasive such as Al2 O3 , etc., a magnetic powder such as farrous alloy and an additive is applied on a film such as PET. At this time, the coercive force of the tape in the running direction is set to >=600 Oe, the residual magnetic flux density to >=1000 G, and the surface roughness to 5-30nm. On the other hand, the magnetic coercive force of the mother tape, to which a signal is preliminarily recorded, is set to 2000-5700 Oe to enable the signal recording on the cleaning tape having the coercive force of 600-2000 Oe. By means of transferring the signal of this mother tape to the cleaning tape with a contact transfer system, the magnetic head is unnecessitated and the satisfied electromagnetic conversion characteristic is obtained.

Title: Rubber reinforced monovinylidene aromatic compound polymers and manufacture
Inventor: JIYURIAN HEREN JIYOSEFU MARIA
IPC: C08F279/02
Filed: 1983-06-03
Abstract: A rubber-reinforced polymer of a monovinylidene aromatic compound. e.g., styrene, having rubber of two different particle sizes distributed through the polymer matrix and exhibiting a desirable balance of gloss and toughness properties is continuously prepared using mass polymerization techniques. Specifically, the rubber-reinforced polymer is prepared by polymerizing a solution of the rubber and monovinylidene aromatic compound in the presence of a graft promoting initiator, e.g., dibenzoyl peroxide, and at conditions sufficient to form a dispersion comprising a continuous phase of polymer having discrete, rubber particles of a particle size from 0.5 to 1.5 micron dispersed therethrough. Subsequently, additional amounts of rubber are added to the polymerization mixture and polymerization continued at conditions such that the newly added rubber is dispersed throughout the continuous polymer phase as discrete particles having a particle size from 4 to 10 microns. The polymerization is completed and the rubber subsequently crosslinked.

Abstract: PURPOSE: To provide a continuous injection molding machine which can improve the production capacity with simplified construction by closing the cavity port of a mold immediately after completing an injection molding and retaining the closed state to cool it so as to thereby shorten the molding step.  
     CONSTITUTION: When upper and lower molds tightened at clamp E are fed to an injection molding section A and molten metal is injected into the cavity in the mold, a manifold 4 is immediately slightly floated from both mold rows 2, 2 upon retarding of an injection cylinder 5 to thereby close the cavity port 3 by the seal 7 of the manifold 4. This state is retained, and the molds are moved to a cooling section B even if the molten metal in the cavity is not yet sufficiently hardened. The molds are cooled at the section B in the state that the respective cavity ports 3 are closed by sealers 8 integrated with the seals 7 to thus gradually harden the molten metal in the cavity. Accordingly, it can transfer the molds from the completion of injection to the cooling section in short time.

Abstract: PURPOSE:To reduce a pattern distortion irrespective of both a center axis slip and an electron lens distortion produced in time of sealing an electron gun and a vacuum envelope, by installing a positive pole electrode between a positive electrode and a shield mesh electrode independent of the positive electrode that is stuck and made up on the inner wall of a funnel. CONSTITUTION:An electron gun to be installed inside a neck 13 consists of an electron beam generating electrode group 20, a paired vertical deflecting plate 22, a paired horizontal deflecting plate 23, a collector electrode 24 for secondary electron absorption and pattern distortion correction use, a shield mesh supporting electrode 25, a shield mesh electrode 26 and a shield electrode 24 between deflecting plates. A positive pole electrode 40 is impressed with the specified high voltage out of an anode 34 via a conductive contact arm 41. The region of an electron lens 37 conductive toward the extension of deflection is almost determined with a distance for a diameter of the shield mesh 26 or thereabouts whereby this distance is negligible at the region of the anode 34 so that such a tube structure that these problems such as an error of sealing accuracy in the electron gun, positioning accuracy in a valve spacer 29, out of roundness in a funnel 12, inclination in the neck 13, etc., will not concern distortion in an electron lens 37 can be brought to fruition.

Abstract: PURPOSE:To quicken a read speed of picture information by tentatively storing information read by plural arrays of photoelectric conversion elements arranged in parallel to a storage means and adding the information to output information of the photoelectric conversion elements. CONSTITUTION:Sets of information Ain, Bin read by photoelectric conversion elements Ai, Bi arranged in parallel are digitized by A/D converters 11A, 11B respectively and the digital signal is transferred to address 13A, 13B. The adder 13B adds both the information sets and outputs the result, while the information Ain is stored in a memory 12 and read and the adder 13A adds it to the information Bin and the result is outputted. Thus, the output information of the adder 13A is Ai1+Bi2 and the output information of the adder 13B is Ai2+Bi2 for times t-2t. Thus, the read speed is decreased to 2S/t (S is read resolution) and the read speed is quickened without decreasing the resolution.

Title: Method for shortening access time of cd-rom driving device and cd-rom driving device therefor
Inventor: UEDA YOSHIHISA
IPC: G11B7/085
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To shorten an access time by adjusting a revolution of a CD-ROM disk with a move of an optical pickup and controlling the number of revolutions corresponding to a target address when the pickup is positioned at the target address. SOLUTION: When an accessing operation is started, a spindle revolution speed adjusting part 7 detects the rotation of CD-ROM disk 1 based on a revolution control signal from a digital signal processing part 5. It detects also a moving direction of an optical pickup 2. When the pickup 2 is moved in the radial direction of the disk 1, the moving amount is detected by an encoder 3, which transmits pulses to a microcomputer 6 and the spindle revolution speed adjusting part 7. The adjusting part 7 outputs a kick signal and a brake signal along with the move of the pickup 2 based on the number of revolutions of the disk 1, the moving direction of the pickup 2, and its moving amount. A driving part 8 receiving this signal outputs a signal to the spindle motor 9 to adjust the number of revolutions of the disk 1.
