Title: Flexible disk device
Inventor: YANO NORIO
IPC: G11B5/024
Filed: 1985-10-15
Abstract: PURPOSE:To cope with the high recording density as well while keeping the existing constitution of the mechanism and the recording format, by switching in many steps the delay of the time when the erasion is started for both edges of a data area in the radius direction against the writing start of data. CONSTITUTION:The erase-on delay time is set in many steps so that it is set at 300mus with the most outer circumferential track 0 and then increased toward the inner circumference by 100mus at every 20 tracks. In such a way, the erase-on delay time of a flexible disk device can be set within a prescribed setting range even in case the inversion density of a magnetic flux is increased with the distance (x) between the record/reproduction gap and the erasion gap and the revolving variance of a recording medium set as conventional. Thus the recording density is improved while keeping the conventional, recording/reproducing head and the size and accuracy of a driving motor for the recording medium since the erase-on delay time is switched in steps.

Filed: 1989-09-05
Abstract: PURPOSE:To prevent water from remaining in a water flowing pipe even in such a structure that the cooled purified water is supplied through the water flowing pipe by carrying out such a reverse water supply operation that the pure water passed through a water purifying unit is returned to a water supply tank when water supply is finished. CONSTITUTION:The source water in the water supply tank 9 is allowed to flow through the water flowing pipe 10 where contaminants and malodor are removed by the cleaning action of superfine porous membrane of a water purifying filter 12 and activated carbon. When the water supply action of a water supply unit 11 is stopped, the forward signal Sa outputted from the water supply unit 11 to a control unit 16 is stopped and a backward signal Sb is outputted for a specified period. Thus, the gear pump in the water supply unit 11 is reversely revolved for the specified period, and the pure water remained in the water flowing pipe 10 is moved to the reverse direction opposite to the water supply direction to be returned into the water supply tank 9. As a result, the water flowing pipe 10 communicating to the outside through a water supply port 14 is early dried and kept hygienic without the propagation of various germs and the sticking of deposit.

Title: Drift compensation circuit
Inventor: TANIMOTO YOSHIO
IPC: H03M1/10
Filed: 1990-08-31
Abstract: PURPOSE:To compensate a drift at each device completely by obtaining a difference between a mean voltage and an integration voltage by a 2nd differential amplifier and giving its output to other input of a 1st differential amplifier. CONSTITUTION:A 2nd differential amplifier 8 detects a difference between an output voltage (f) of an averaging circuit 6 and an output voltage (g) of an integration device 7 to control an output voltage (b). Thus, since the output voltage (g) of the integration device 7 is a mean voltage of an output voltage (c) of the 1st differential amplifier 1, the ideal relation of equation is always kept. Thus, an optimum input is always given to an A/D converter 4 and drift of each device such as the 1st differential amplifier 1 is compensated.
