Title: Pulse motor driver
Inventor: OKAWARA HIROTO
IPC: H02P8/22
Filed: 1991-06-04
Abstract: PURPOSE:To obtain a low vibration, low noise driver by providing means for controlling the driving frequency of a pulse motor and a driving means for modifying the driving waveform of the pulse motor according to the driving frequency. CONSTITUTION:A control microprocessor 101 delivers a data corresponding to the voltage being applied on each phase of a motor to a D/A converter 102. The input value is then subjected to D/A conversion 102 and delivered, as an actual voltage value, to a driver 103. Rotational direction of a pulse motor 104 is determined through combination of four output voltages from the driver 103 and the rotational speed is determined by the intervals of the output voltages. The combination of voltage and the interval of output voltage are determined by means of the control microprocessor 101. If n=2, m=0, for example, voltages on the table has such values as phase A = inverted phase A = phase B=00h, inverted phase B=ffh which are then subjected to D/A conversion through the D/A converter 102 to bring about phase A = inverted phase A = phase B=0V, inverted phase B=5V.

Filed: 1986-06-10
Abstract: PURPOSE:To obtain the titled medium which can maintain an error rate and S/N in the good state for a long period of time by providing a honeycomb- shaped underlying layer on a high-polymer film and providing a diagonally vapor deposited film thereon. CONSTITUTION:The honeycomb-shaped underlying layer 2 is provided on the high-polymer film 1 and the diagonally vapor deposited film 3 is provided thereon; further, a protective layer 4 is provided thereon. A PE terephthalate having 10mum thickness is used as the high-polymer film 1 and an NiCr layer is provided to 0.25mum thickness as the underlying layer 2. The NiCr (34wt% Cr) is formed by depositing the same as columnar particles on the film 1 by a high-frequency sputtering method so as to segregate the Cr on the particle surfaces, then immersing the film for 3sec in a dilute hydrochloric acid so that dissolution progresses selectively in the parts except the segregated parts to form the projections in the honeycomb shape.

CONSTITUTION:In the window-type air conditioner, the outside air is delivered to the side of a condenser 5 by the propeller fan 2 driven by a fan motor 3, and the air heated to a high temperature by absorbing heat in the condenser 5 is discharged to the atmosphere. In this case, the mouth ring 1 provided at the partition plate 4 separating the suction side and the blow-off side from each other is projected from the plate to a height H=15-30mm. on the suction side, instead of being projected to the blow-off side. Accordingly, air is casued to flow while sufficiently spreading to end parts of the condenser 5, the pressure on the blow-off side is reduced, and backflow is prevented. In addition, by bending an end face of the ring 1 to the inside with a radius of curvature R=5-10mm., condensed water rolled up by the fan 2 is prevented from entering the suction side to adhere to the fan motor 3 or the like.
