Title: Production of perpendicular magnetic recording medium
Inventor: MEGURO MASASHI
IPC: G11B5/845
Filed: 1989-02-15
Abstract: PURPOSE:To improve the squareness ratio and surface characteristic in the perpendicular direction of the perpendicular magnetic recording medium by impressing a magnetic field in the longitudinal direction of a nonmagnetic base to a magnetic coated film contg. acicular magnetic powder, and then impressing a rotating AC magnetic field thereto to perpendicularly orient the coated film. CONSTITUTION:The device of this method is constituted of a longitudinally orienting mechanism part 2 which impresses the magnetic field in the longitudinal direction of the nonmagnetic base 1 to the magnetic coated film contg. the acicular magnetic powder formed on the nonmagnetic base 1 and a perpendicularly orienting mechanism part 3 which impresses the rotating AC magnetic field to the magnetic coated film. These parts are provided in this order at a prescribed spacing in the traveling direction (arrow A) of the nonmagnetic base 1. The rotating AC magnetic field is impressed to the magnetic coated film after the acicular magnetic powder is aligned approximately in the longitudinal direction of the nonmagnetic base 1 and, therefore, the orientation of the acicular magnetic powder in the thickness direction of the magnetic coated film is smoothly executed. Since there is no need for increasing the intensity of the AC magnetic field more than needed in the impression of the rotating AC magnetic field, the disturbance in the orientation by a demagnetizing field and the surface roughening by magnetic flocculation is suppressed.

Title: Alkaline-zinc battery and its manufacture
Inventor: HAYASHI AKIRA
IPC: H01M6/06
Filed: 1987-02-20
Abstract: PURPOSE:To obtain high discharge utilization even in very high rate discharge such as stroboscope discharge by selectively amalgamating only zinc particles in the vicinity of the surface facing a positive mix of a gelled negative electrode. CONSTITUTION:Nonamalgamated zinc alloy powder is used as zinc alloy powder, and a separator 3 in which a thin layer containing, for example, mercuric oxide or mercury salt which is soluble or difficult to dissolve in an alkaline electrolyte is formed on the surface facing a gelled negative electrode 4 is used. Only the zinc alloy particles of the gelled negative electrode 4 which are in contact with the separator 3, that is, facing a positive mix 2 are amalgamated. Thereby, in spite of the very small content of mercury, the performance in very high rate discharge such as stroboscope discharge is increased.

Title: Ttl circuit
Inventor: TAWARA AKINORI
IPC: H03K19/088
Filed: 1984-02-29
Abstract: PURPOSE:To attain wire dot connection while decreasing a time when the output logic transits from L to H by introducing a transistor (TR) which is turned on at the trnsient state where the output logic is switched from L to H. CONSTITUTION:A TR41 of an output section 43 is turned on temporarily only when the output logic OUT transits from L to H. A TR42 is connected in series with an output 18 of an output TR17 to form a conducting path leading to a power supply VCC. That is, when the TR42 is turned on, its conductive path is formed. Since the TR42 is turned on/off respectively according to turning on/off of the TR41, the conducting path is formed only when the logic OUT transits from L to H to charge rapidly a load capacitor CL thereby decreasing the time required for the logic OUT transited from L to H. The TR42 is turned on only at the transition and turned off in other cases, the wire dot connection is attained.

Filed: 1989-02-17
Abstract: PURPOSE:To enhance reliability in detection by obtaining 1st and 2nd counter electromotive force direction detection circuits which respectively detect the direction of counter electromotive force generated in a motor according as a disk table is pulled or pushed. CONSTITUTION:When the disk table is pulled, the counter electromotive force heading toward the 1st counter electromotive force direction detection circuit 81 from the diode D4 of a driving circuit 5 for the motor 4 is generated. A transistor TRTr11 is connected and an L signal is supplied to a control circuit 7. The circuit 7 decides based on the L signal that the table is pulled, and it actuates a TRTr1 and Tr4 and rotates the motor 4. It judges that the table reaches an opening position by actuating a limit switch 3, and it stops the Tr1 and the Tr4 and stops the motor 4. Since the counter electromotive force heading toward the 2nd counter electromotive force direction detection circuit 82 from a diode D2 is generated by pushing the table, the action same as above is performed. Whether the table is pulled or pushed is detected by the circuits 81 and 82.
