Title: Disk-shaped magnetic recording medium
Inventor: YOSHIDA YUTAKA
IPC: G11B5/82
Filed: 1988-04-28
Abstract: PURPOSE:To decrease the difference between the reproduced outputs near the outermost circumference and the innermost circumference in a range where a recording wavelength is short by incorporating metal powder having the coercive higher than 1,400oersted and a resin of a specific vinyl chloride copolymer into a magnetic layer. CONSTITUTION:The ferromagnetic powder incorporated into the magnetic layer of the disk-shaped magnetic recording medium is the metal powder having the coercive force higher than 1,400oersted and a liquid dispersion contg. the vinyl chloride copolymer as a binder contg. at least an epoxy group, hydroxyl group and sulfonic acid radical in said powder is supplied onto a nonmagnetic base and the resin cured by a heating treatment is added thereto to form the magnetic layer. A ferromagnetic metal alone or the alloy thereof (Fe, Co, Ni, Fe-Ni, Fe-Co, Fe-Ni-Co, etc.) is usable as the metal powder. The saturation magnetization quantity is preferably >=20emu/g and the specific surface area 40-65m<2>/g. Since the vinyl chloride copolymer is used as the binder, the dispersion of the metal powder is improved and the effect with the reproduced product is much more remarkable.

Title: Watch
Inventor: MOCHIZUKI EIJI
IPC: G04G99/00
Filed: 1991-02-07
Abstract: PURPOSE:To enable a person handicapped in seeing and/or hearing to recognize the indication of watch function from the finger touch easily by indicating the watch function by braille with indication parts able to project and sink in the surface for indicating the function. CONSTITUTION:Normally, there is nothing projected on the indication surface 5 of a watch body 1 and the surface is plane. When the time indication is necessary, by pushing an indication button 3, indication parts 1b project out of the indication surface 5 to indicate figures, etc., as braille. For example, by using a metal or semiconductor for the indication parts 1b which swells by the effect of electric current, the indication parts 1b swell during current passing and project out of the indication surface 5. Also, by using electromagnet 6 and permanent magnet 7 in combination for the indication parts 1b, the electromagnet 6 and the permanent magnet 7 repulse each other during current passing and the permanent magnet projects out of the indication surface 5. By this, a person handicapped in seeing and hearing can easily recognize the indication of the watch function by finger touch.

Title: Run-away monitor timer circuit device
Inventor: MASUDA CHINATSU
IPC: G06F11/30
Filed: 1994-05-18
Abstract: PURPOSE:To monitor abnormality such as a of a run away CPU by comparing the timer value that a timer outputs with the expected value stored in an expected value register, and generating and outputting a system reset signal when their coincidence is detected. CONSTITUTION:An expected value rewriting means 12 rewrites the expected value, stored in the expected value register 13 when the CPU of a microcomputer 11 is in normal operation, into a new expected value which does not match the timer value outputted by the timer 3. A coincidence circuit 14 compares the timer value outputted by the timer 3 with the expected value stored in the expected value register 13 to detect their coincidence. A system reset signal generating circuit 5 generates and outputs a system reset signal when the coincidence circuit 14 detects the coincidence between the timer value and expected value. Consequently, abnormality such as a run away of the CPU of the computer 11 can be monitored without impeding operation as a general timer.
