摘要： PROBLEM TO BE SOLVED: To provide a vibrator which can promote miniaturization. SOLUTION: In the vibrator 1, a magnetic circuit section is formed by a pair of magnets 8 arranged side and side and a first yoke 11 and a second yoke 9 opposed to face each other via the magnets 8. A driving coil 12 for making current flow in a direction perpendicular to a direction of a magnetic field is inserted between the magnets 8 and the first yoke 11 and current to the driving coil 12 is controlled by a current controlling section 16. Further a dead-weight 7 is fixed to an outer periphery of the magnet 8 and the dead- weight 7 is supported by a spring member 5. Thereby when current flows through the driving coil 12 at a definite period, the magnet 8, the dead-weight 7 and the second yoke 9 make reciprocal linear vibration in a direction where arranged side by side by cooperation between driving force and pressing force of the spring member 5. In order to increase the reciprocal linear vibration, the device 1 may be extended in the direction where arranged side by side and volume increase of the device 1 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To perform the start appropriately by minimizing the output pulse at the starting stage to be supplied to a coil, and enlarging the output pulses in order more than the previous output, thereby increasing the amplitude of a needle to the specified amplitude. SOLUTION: At start, starting is performed in the starting procedure present in a start setter 50. In this setting the output pulses at the initial stage of starting to be supplied to the coil 11 of an electromagnetic minimized, and then the output pulses are enlarge more than the pervious output is average, whereby the amplitude of the needle is increased gradually, and then it is shifted into normal operation mode geared to the output of a sensor 39. Then rate of enlarging the output pulses more than the previous output is decreased at the point of time when the amplitude of the needle reaches the smaller amplitude than the specified amplitude, an when it reaches the specified point, it is shifted to normal mode, whereupon it can be smoothly connected to the normal operation mode to perform the oscillation of specified amplitude. Hereby, the start can be performed appropriately.

摘要： PURPOSE:To operate at a high speed by providing a plurality of coils radially at one of a pair of magnetic materials moving relatively to flow currents of reverse direction to adjacent coils, and forming radially at least one slit. CONSTITUTION:A plurality of concentrical recesses 14 are formed on a stator 3 for forming one of a pair of magnetic materials (the other is omitted) moving relatively. An air coil 15 is wound therein, and terminals 15a, 15b are connected so that currents flowed to the adjacent coils 15 become reverse. At least one slit 16 is radially formed on the stator 3. The terminals 15a, 15b are inserted to a terminal board 17 so as not to contact with the stator 3 by a side plate 23. The other magnetic unit is moved by a magnetic flux generated at the stator 3 by flowing a current to the coil 15 and a magnetic flux of the other magnetic unit, not shown. Slits 16 are formed on the stator 3 to prevent an eddy current from generating. Thus, the magnetic force is increased to operate at a high speed.
