    Abstract: The iron core motor device has an iron core motor with a rotor (10). The rotor (10) can be rotatably driven about a predetermined angle by electromagnetic induction in dependence on a phase position of the current supply of a two phase spool (21, 22) wound on an iron core. A control device (51) generates a drive signal based on the phase information of reverse voltages with different phase, which are induced in the two phase spools (21, 22). The control device (51a) reduces the reverse voltage which is induced in the spool whose current line is interrupted by phase switching of the supply of the two phase spools (21, 22). A predetermined time delay (TD) is provided with the switch-off time control of the switching device. This is connected to the spool (21) whose current line is interrupted.

    Abstract: AN IRON MOTOR DEVICE INCLUDES AN IRON CORE THE MOTOR THE ROTOR OF WHICH IS ROTATIONALLY DRIVEN A PRE - SET ANGLE BY ELECTROMAGNETIC INDUCTION RESPONSIVE TO PHASE SWITCHING OF CURRENT SUPPLY TO TWO - PHASE COILS WOUND ON AN IRON CORE, AND A DRIVING CONTROL UNIT FOR GENERATING A DRIVING CONTROL SIGNAL BASED ON THE PHASE INFORMATION OF DIFFERENTIALLY PHASED BACKWARD VOLTAGES INDUCED IN THE TWO - PHASE COILS. THE DRIVING CONTROLUNIT CAUSES SHORTING OF THE BACKWARD VOLTAGE INDUCED IN THE COIL THE CURRENT SUPLLY IN WHICH IS INTERRUPTED BY PHASE SWITCHING OF CURRENT SUPPLY TO THE TWO - PHASE COILS BY PROVIDING A PRE - SET TIME DELAY IN THE TURN - OFF TIMING OF THE SWITCHING DEVICE CONNECTED TO THE COIL THE CONDUCTION IN WHICH IS INTERRUPTED. THE METHOD FOR DRIVING CONTROLLING THE IRON CORE MOTOR DEVOCE IS ALSO DISCLOSED.

    Abstract: PROBLEM TO BE SOLVED: To provide a motor producing high torque by reducing cogging. SOLUTION: A motor 10 is constituted of a shaft 11, a stator 30 fixed to the shaft 11, and a rotor 20 disposed so as to rotate around the shaft 11 against the stator 30. The rotor 20 has a magnet 23 so formed as to have 10×(n) magnetic poles ((n) is a natural number). The stator 30 holds a ring 33 fixed to a stator housing 31 and an insulator 35 wound with a coil 36, with its one end fixed to the ring 33 and the other end formed with a salient pole section 34b. The salient pole section 34b has an iron core 34 which constitutes a magnetic circuit together with the magnet 23 of the rotor 20. The magnetic core 34 is so disposed as to have 12×(n) magnetic poles ((n) is a natural number).

    Abstract: PROBLEM TO BE SOLVED: To provide a compact reproducing apparatus for a digital image or the like, which can easily be operated while avoiding complicatedness.
    SOLUTION: The reproducing apparatus has connection terminals 3, 4, 5 directly connected to video input terminals of a television receiver or the like, and outputs at least either of image data and audio data stored in a storage medium 6. Thus, no troublesome work such as wiring is required. Further, since having only to load the storage medium 6 to a loading unit 8 resulting in being connected to the television receiver permits output of image data or the like to the television receiver or the like, troublesome operations can be avoided unlike those in prior arts. Moreover, since the apparatus is sized just to directly connect the terminals 3, 4, 5 to video input terminals, the apparatus is sized compact and excellent in the portability.

    Abstract: PROBLEM TO BE SOLVED: To provide a motor which can prevent lubricating oil from leaking out of a bearing while a distance between a reference plane for the attachment of the motor and the chucking plane of an optical disc is reduced and avoid the wear of the chucking part, by preventing a turntable and the bearing from being brought into direct contact with each other. SOLUTION: This motor 10 has a stator 22 and a rotor 20 turned relatively to the stator 22. A bearing 72 supports a shaft 40 with lubricating oil. A lubricating oil leakage preventive member 76 for preventing the lubricating oil of the bearing 72 from leaking into a turntable 24 side is provided between the turntable 24 and the bearing 72. A thrust bearing 74 for preventing the turntable 24 and the bearing 72 from being brought into direct contact with each other is provided between the turntable 24 and the bearing 72.

    Abstract: PROBLEM TO BE SOLVED: To suppress excessive torque, and to prevent break of a mechanism portion and a circuit portion by providing a clutch mechanism which causes a rotation inputting portion to race idle, if torque exceeds a constant value, between the rotation inputting portion and an accelerating mechanism. SOLUTION: Between a handle 8 being a rotation inputting portion and the rotation inputting gear 4 of an accelerating mechanism, a generator 1 has a clutch mechanism 20 for suppressing an excessive rotation input. When the handle 8 is rotated at an excessive rotational speed, the clutch mechanism 20 operates. Namely, a wave washer 24 is deflected by the force of its clutch board 21 which tries to rotate the gear 4 excessively along with the handle 8, and protrusions 22 of the clutch board 21 comes off from holes 23 of the gear 4. Consequently, the handle 8 operates so as to run idle as against the gear 4. The clutch mechanism 20 performs this action by its combination with a control circuit to be formed on a circuit board in the generator. Consequently, it is possible to rotate the gear at an appropriate speed and to perform generation.
