IPC: H02J3/18
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a power factor controller whose power factor can be raised by adding a phase advance capacitor whose capacity is smaller than an existing equal capacity phase advance capacitor at the time of changing a facility and small capacity capacitors can be made to follow a sequential supply/interruption operation. SOLUTION: A power factor controller 1 selects the capacity of a capacitor so that the power factor becomes 100% on the basis of the reactive power of a facility. The controller 1 is divided into phase advance capacitors C1, C1, C1< of equal capacity in accordance with a situation. When it cannot be divided into the phase advance capacitors of equal capacity, a phase advance capacitor C2 of small capacity corresponding to the capacity of the remaining capacitor is added. The phase advance capacitor C1 of equal capacity is controlled and then the phase advance capacitor C2 of small capacity is controlled.

Title: Clock with radio receiving function
Inventor: SATO TAKESHI
IPC: G04G15/00
Filed: 1987-12-18
Abstract: PURPOSE:To clearly indicate a user when a set time comes, by arranging a clock which outputs a radio sound when said set time comes so that an alarming signal is outputted if the output radio sound is at a low level. CONSTITUTION:When time coincidence is found to a set time in a set time coincidence circuit 1, a radio receiving circuit 2 starts receiving signals. The received audio signals are outputted from a speaker 7 via a selecting circuit 6. Meanwhile, when the receiving circuit 2 starts receiving signals as described above, if the level of the received audio signals is smaller than a predetermined level, a level detecting circuit 3 outputs a signal to actuate a signal sound sending circuit 5. Simultaneously, the selecting circuit 6 is switched to the side of the signal sound sending circuit 5, so that an alarming sound produced in the circuit 5 is generated from the speaker 7. Therefore, even when the level of received signals of the radio is smaller when the set time comes, the user can be positively informed of the fact that the set time comes.
