SOLUTION: A water turbine 8 of which the flow rate is changed in accordance with rotation number is provided in the downstream of a faucet 1, and rotation of a shaft 11 of the water turbine 8 is transmitted through a speed increasing gear mechanism comprising a first and a second gear mechanisms 14, 15 to a rotor 31. Induced power is generated in accordance with rotation of the rotor 31, this is used as driving power to accurate a rotation control circuit, the rotation control circuit generates a brake control signal BS corresponding to difference between a target rotation cycle of the water turbine 8 and a rotation cycle of the rotor 31 equivalent to a target flow rate, and this is outputted to a brake circuit. Braking force corresponding to rotation speed difference is applied to the rotor 31, the rotation cycle of the rotor 31 is controlled to coincide with the target rotation cycle, and a flow rate discharged from an outflow port 5 is controlled to be the target flow rate.

摘要： PURPOSE: To reduce the vibration and noise of a coil and a stator yoke by providing a means for preventing vibration and noise caused by the switching of coil current. CONSTITUTION: A brushless DC motor is constituted by combining a rotor 2 and a stator 10 and the rotor 2 consists of a rotor yoke 3, a back yoke 4, and a permanent magnet 5. The stator 10 consists of an upper first stator yoke X, a coil part, a bearing 18 for supporting a lower second stator yoke Y and a shaft 6 so that they rotate freely. A coil part 12 consists of resin bobbin 14 with flanges at both terminals and a coil winding 15 wound around it. The coil part 12 is subjected to vacuum press-fit treatment for press-fit impregnating thermosetting resin in vacuum and further is subjected to heat treatment for curing resin, and then is incorporated into the stator 10. As a result, the coil winding 15 and the bobbin 14 are completely sealed, thus suppressing the electromagnetic vibration of the coil winding generated owing to the high-speed switching of coil current.

CONSTITUTION:In producing device for a magnetic field which generates a uniform magnetic field in a gap 7, the saturation magnetic flux density of a soft magnetic material constituting a yoke 3 and a strut 4 is made higher than the saturation magnetic flux density of a soft magnetic material constituting a pole piece. Besides, the pole piece is divided into a central part 21 being movable in the vertical direction and a peripheral edge part 22 fixed to a permanent magnet 1 and the thickness of the peripheral edge part 22 is made larger than that of the central part 21, while a material having a higher saturation magnetic flux density than the soft magnetic material constituting the central part 21 is used as the soft magnetic material constituting the peripheral edge part 22 of the pole piece. According to this constitution, the strength of the magnetic field in the gap 7 is improved without complexing a structure and also a means for making the magnetic field uniform, which enables to fine adjustment of the magnetic field in the gap.

摘要： PURPOSE:To facilitate the manufacture of the title magnetic field generating device, to effectively concentrate magnetic flux in the vicinity of the center of the air gap and the generate a high strength magnetic field uniformly without increasing magnetic material by a method wherein the circumferential part of a permanent magnet part is formed thicker than the center part. CONSTITUTION:A magnetic circuit is composed of a pair of permanent magnet part 1, on which air gap 5 is formed, and a structure formed in such a manner that a pair of magnetic field adjusting pole pieces, which are fixed to the permanent magnet part 1 are, magnetically coupled by a tabular yoke 3 and a support pole 4. At this point, the thickness t2 pf the circumferential part 12 of the permanent magnet part 1 is constructed so as to become thicker than the thickness t1 of the center part 11. Concretely, first, a disc-shaped permanent magnet part of thickness t1 is formed, and then the circumferential part of thickness t2 is formed by increasing the magnet on the outside part only. Also, the piece 2 can be manufactured by a simple method in which only a tabular pure iron is cut and surface-process is conducted. Using the same quantity of magnet material as before, a high strength and uniform magnetic field can be generated from the part in the vicinity of the air gap center, and the magnetic circuit of the structure which is formed by the technique easier than that heretofore in use, can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal panel which is not affected on display by a spacer in the both of an effective pixel and a ineffective pixel without raising a cost and also which is excellent in display quality. SOLUTION: When a high frequency AC voltage is selectively applied on a piezoelectric element 1 from a high frequency power source control circuit so as to generate an ultrasonic vibration, the vibration energy is converged onto the fluid level of a fluid storage part 4, i.e., the position of a nozzle 5 by a concave lens 2. Thus hardening resin liquid in the fluid storage part 4 is made to be minimal liquid drops by the energy converted onto the fluid level and discharged via the nozzle 5. Then the minimal liquid drops are discharged at a plurality of places from the nozzle 5 to the position of the black matrix of a color filter board by head positioning control and, after that, the hardening resin liquid is hardened. Thus the liquid crystal gap spacer is formed in the black matrix being the area other than the effective pixel.

摘要： PROBLEM TO BE SOLVED: To make discharge liquid drops further finer without being influenced by a nozzle diameter. SOLUTION: In a solid ink jet printer, an ink solid at ordinary temperatures is heated and melted to be a liquid ink 12, and the liquid ink 12 is discharged by an ink jet method. In the printer, when a high frequency AC voltage is selectively impressed to a piezoelectric element 1 from a high frequency power supply control circuit to generate ultrasonic vibrations, the vibration energy is converged by a concave lens 2 to a level surface of an ink storage part 4, that is, a position of the nozzle 5. The liquid ink 12 in the ink storage part 4 is turned by the energy converged to the level surface to minute liquid drops (liquid drop diameter is smaller than 18 μm, preferably, not larger than 10 μm) and discharged from the nozzle 5 towards a recording paper.
