摘要： A binary information display apparatus displays braille information with high accuracy by means of four braille pins, which are actuated by a stepping motor having a stepping angle of 45.degree. and, hence, eight step positions. The apparatus includes four pins; a triplet cam which acts on ends of three pins out of the four pins so as to independently urge such three pins to selectively project from a display surface of a pin-supporting member and to selectively retract the same behind the display surface; a stepping motor for rotating the triplet cam about an axis thereof; and a fourth cam portion which actuates the remainder of the four pins. The motor can perform consecutive seven steps at 45.degree. intervals, starting from a position where a rotation restricting projection on the fourth cam portion abuts a stopper step surface on the pin-supporting member, without causing rotation of the fourth cam portion. The state of the fourth pin is therefore not changed during such consecutive stepping of the stepping motor over seven steps. With the above-described structural arrangements and resulting operations thereof, it is possible to display eight types of braille information. Similarly, eight types of braille information can be displayed by reversing the motor. Consequently, sixteen types of braille information can be produced by the apparatus of this invention.

摘要： A cooling apparatus for electronic components comprising a plurality of radiating fins formed in a heat sink which is in contact with the electronic components, where at least one pair of the radiating fins are formed in parallel with one another. A motor for driving a fan to air-cool the electronic components fits in a groove formed by the radiating fins such that the motor axis is in the longitudinal direction of the groove. A motor-body support is provided on the radiating fins so as to support the motor fitting in the groove. A printed board is connected to a terminal of the motor and set up on the upper ends of the radiating fins, and a holding ridge is formed on the printed board for fitting in the groove so as to cooperate with the motor-body supports in clamping the motor therebetween.

摘要： A motor drive control method and an apparatus therefor in a motor used in an adjusting device for adjusting a physical amount such as a temperature of a heat-generating member, wherein a load on a bearing of the motor caused by frequently repeating drive/stop of the motor can be reduced; thereby, prolonging the service life of the motor. The temperature of the heat-generating member is detected by a temperature detection sensor. A comparison calculating unit calculates a temperature change rate K.sub.n or the like in order to recognize the temperature of the heat-generating member and a change state (such as, a temperature change rate), and selects a rotating speed change characteristic appropriate for the change state at such time. An indication signal for changing the rotating speed of the motor on the basis of the selected characteristic is outputted to a motor control driver in order to perform drive control for the motor. In this manner, drive/stop of the motor can be avoided from being frequently repeated, and a load on the bearing of the motor is reduced.
