Title: Resonator
Inventor: TANIGUCHI TETSUO
IPC: H01P1/205
Filed: 1992-01-10
Abstract: PURPOSE:To enable adjustment to a prescribed resonance frequency by providing an extracting terminal pulled out of a coil electrode and plural band-shaped trimming electrodes formed in a ground electrode so as to be connected with the ground electrode. CONSTITUTION:When a trimming electrode 30 is disconnected, the shield effect of a magnetic field component is reduced. This is equivalent to enlarge the magnetic field component of a resonator 10, and the resonance frequency of the resonator 10 is lowered. Further, when the number of electrodes 30 is increased, the change of the resonance frequency is enlarged as well. By increasing the number of electrodes 30 to be disconnected, the resonance frequency is lowered. In such a resonator 10, the resonance frequency is dispersed by fine difference such as the dimension such as the length or thickness of a coil electrode 14 and a gap between a ground terminal 16 and an extracting terminal 18 or the like. In this case, the resonance frequency can be set at a prescribed value by trimming the electrode 30 and in the case of manufacture, the number of defective articles can be decreased.

Filed: 1980-02-23
Abstract: PURPOSE: To enable a high-speed and accurate orientation to be performed by a small-sized NC controlling device by a method wherein the main shaft orientation is performed without being returned to an origin nor stopped in the rotation, in an OC machine tool.  
     CONSTITUTION: An angle M from the mechanical origin MRP to a stop position CP and an angle N from one rotation signal generating position RTSP to the origin MRP are preset in an internal switch 151. When an orientation command ORCM is issued during the rotation of the main shaft 101, the main shaft moves round at speed VOR and generates the one rotation signal RTS to cause -M to be set in an updown counter 153. When the main shaft further rotation and the content of the counter 153 is changed, -N is set in the counter. Thereafter, the main shaft 101 is driven according to an error voltage appearing in an output of a DA converter in proportion to the content of the counter 153, and when the content of the counter 153 is reduced to zero, a finish signal ORED is generated from AND gate 159 to cause the orientation control to be finished.

Abstract: PURPOSE:To prevent water included in effluent air from being frozen without lowering the result coefficient of a device by reducing the number of revolutions of a motor driving an air compressor in the case where temperature of the air effused from an expander is lowered to a set temperature or lower. CONSTITUTION:Provided in normal operation temperature of air sucked into a device is low, the temperature of effluent air from an expander 4 through an air compressor 1 and an intermediate condenser 3 is low. The temperature of the effluent air is detected by a temperature sensor 15 and is inputted to comparator means 16 of a controller 14 where it is compared with a set temperature inputted from setting means 17. As a result, if the detected temperature is lower than the set temperature, an instruction is outputted from output means 18 to an inverter 13. Frequency of AC voltage supplied from a commercial power supply 11 through a rectifier circuit 12 is lowered to reduce the number of revolutions of a motor 2. Hereby, capabilities of the air compressor 1 and the expander 4 are reduced, and finally the temperature of the effused air is raised to a freezing point or higher.
