摘要： A high-performance filter for an intake air for a gas turbine according to the present invention includes a low-efficiency filter media and a high-efficiency filter media superposed closely on each other in the named order from an upstream side in a direction of an air flow. Each of the filter media is formed with a filtering area of 20 to 35 m2. The filter media having a filtration efficiency of 40 to 70% for particles having a particle size of 0.3 &mgr;m is disposed as a layer upstream in the air flow direction, and the filter media having a filtration efficiency of 90 to 99.99% for particles having a particle size of 0.3 &mgr;m is disposed as a downstream layer. In addition, a filter unit according to the present invention is made using the above filter, Thus, even when the filter unit is used for atmospheric dusts including a high concentration of dusts having a particle size of 0.3 to 0.5 &mgr;m, a life of 8,000 hours or more, and the deposition of the atmospheric dusts in an air compressor or the like in a conventional gas turbine plant can be alleviated, thereby preventing a reduction in power-generating output and ensuring that it is unnecessary over a long period of time to carry out the washing or cleaning of the air compressor and the like and the replacement of the filter. In addition, the filter unit can be placed in a reduced space.

摘要： An electronic timepiece havig a stepping motor driving time indicating hands is provided with a system whereby the stepping motor is selectively driven at one of three different drive power levels, in accordance with the load currently being applied to the motor. Detection of the load level is performed by momentarily sampling a voltage induced in the motor drive coil during a short time interval following a drive pulse. The system provides rapid response to changes in load level, highly stable control, and excellent tolerance to variations in characteristics of different stepping motors and circuit components.

摘要： A pulse motor for clockworks and the like in which the rotor comprises two spaced-apart permanent magnetic disks mounted upon a common shaft and rotatable with respect to a stator. The stator comprises a respective pair of magnetic poles in the plane of each disk, the poles of the pair being interconnected by a shank and a coil wound upon the respective shanks, the coils lying on opposite sides of the rotor. The coils can be excited independently to cause the respective pair of poles to magnetically cooperate with the respective disk and rotate the motor in the forward or the reverse sense.
