Title: Feedthrough emi filter
Inventor: OGATA YASUYUKI
IPC: H03H7/075
Filed: 1994-06-02
Abstract: PURPOSE:To provide a feedthrough EMI filter with a small variation or deterioration in filter characteristic, by using the EMI filter body containing an additive that lowers the sintering temperature and prevents the reaction between a dielectric body and a magnetic body. CONSTITUTION:In a feedthrough EMI filter, an outer circumferential electrode 1 is formed around a composite body 2. The composite body 2 is formed by sintering a mixture of dielectric material, magnetic material and an improvement additive. An inner electrode 4 with a lead terminal 3 is formed in the through hole of the sintered composite body 2. Through the additive added to the composite body 2, a reaction between the dielectric and magnetic materials can be provided in a sintering step. At the same time, the sintering temperature can be reduced, so a decrease in dielectric constant and initial permeability can be prevented. Consequently, a variation and a deterioration in filter characteristics can be reduced.

Title: Speed controller for wound-rotor induction motor
Inventor: ARIMA KANJI
IPC: H02P23/07
Filed: 1988-05-17
Abstract: PURPOSE:To cope with the magnitude of a load or low speed sufficiently without increasing ratings of an eddy current brake by changing automatically a resistance value of a secondary resistor in accordance with inflow power of the current brake and a motor. CONSTITUTION:Excitation current of an eddy current brake 3 is converted into voltage by a detection resistor IrR, and voltage relays RL1 and RL2 are operated in accordance with the magnitude of the excitation current of the eddy current brake 3. Accordingly, secondary resistance r1-r4 of a wound-rotor induction motor 1 are automatically changed over. When negative torque is applied to the motor 1, a resistance value of a secondary resistor is increased to reduce the torque of the motor, so that the eddy current brake torque can bear the negative load torque. On the other hand, in case of low speed, the resistance value of the secondary resistor is reduced, and the torque of the motor 1 is increased.
