Abstract: A motor control device for controlling rotation of a motor by controlling a driving voltage applied to the motor is provided. The device includes a driving voltage control unit configured to control the driving voltage, and a detecting unit configured to detect rotation of the motor. The motor has operating characteristics indicative of relationship between the driving voltage and a rotation speed of the motor, where the operating characteristics have a specific dead-band range of driving voltages wherein the rotation speed of the motor is zero regardless of changes in the driving voltage. The driving voltage control unit performs a low rotation control operation including at least one alternating repetition of a first control operation and a second control operation. The first control operation adjusts the driving voltage to have a value outside of the dead-band range from a value within the dead-band range, while the second control operation adjusts the driving voltage to have the value within the dead-band range from the value outside of the dead-band range. The second control operation is performed after a specific first amount of motor rotation has been detected in the first control operation.

Abstract: A porous body, for a solid electrolytic capacitor, is made from a combination of titanium and aluminum in order to reduce dependence upon tatalum, a material which is now in extremely short supply. First, the titanium hydride and aluminum are milled into an extremely fine micro-powder. Then, the powders are mixed with the aluminum content in the range of 45%-65%, compressed into the desired body shape, and given a three-step heat treatment. In the first step, the body is heated at a temperature of 400.degree. to 500.degree. C. for a dehydrogenation. In the second step, the dehydrogenated body is heated to an alloying temperature which is higher than 500.degree. C., but lower than the melting point of aluminum. In the third step, the alloyed body is heated to a temperature which is higher than the melting point of aluminum (about 1000.degree. C.).
