IPC: H02P7/29
Filed: 1981-09-29
Abstract: PURPOSE:To remove the ripple section of back electromotive force by extracting the high frequency of the variation section of voltage drop between the emitter and collector of a transistor connected in series with an armature circuit as pulses and sampling the output of a back electromotive force detecting circuit by the pulses. CONSTITUTION:A bridge circuit is formed by the motor 2 and resistors 3-5, and a differential amplification circuit 6 detects the back electromotive force of the motor 2 from voltage between the terminals A, B of the bridge circuit. Voltage drop between the collector and emitter of the transistor 11 increases in order to hold constant currents because the impedance of an armature drops when a commutator is short-circuited by means of a brush. The voltages pulses are shaped to predetermined width by means of a by-pass filter 9 and a monostable circuit 10. An analog switch 7 is controlled by the pulses, and the output of the difference amplifier 6 is transmitted to a sample holding circuit 8.

Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a corrugated retainer for a ball bearing to hardly cause the occurrence of seizure between a ball and a retainer to hold a lubricant for a long period, and provide an increased life for a bearing. SOLUTION: Axially expanding ball holder 3 and flat part 4 are formed at intervals of a given distance in the peripheral direction of an annular holding plate 2. Spherical recessed parts 3a and 3a, situated close to the flat part 4, and semicylindrical bodies 3b and 3b in a bent state are connected to the ball holding part 3. The ball holding parts 3 of the annular holding part 2 are combined together facing each other to form a pocket 6 to hold the ball 5. During rotation, the ball 5 is rotated in a state to make contact with the inner surfaces of the semicylindrical bodies 3b and 3b but since a speed is delayed in a contact position, a fear of seizure occurring is almost eliminated. Further, the vicinity of a joint between the ball 5 and the annular holding plate 2 makes no contact with the ball 5 and specified spaces 10 and 11 are formed to form a lubricant reservoir. Instead of bent semicylindrical bodies 3b and 3b, a semicylindrical body having an axial direction coinciding with a pitch circular direction may be emploed.
