Abstract: PURPOSE:To connect a three-phase capacitor to a three-phase AC circuit without using a three-phase transformer and without causing a rush current, by selecting a closed phase of a semiconductor switch so that the switch is closed by a phase of zero of a terminal voltage of each phase semiconductor switch. CONSTITUTION:At the time when a U phase line voltage of a three-phase AC power source 10 is zero, a U shape positive direction thyristor FU and an FV phase negative direction thyristor NV are ignited, capacitors CU, CV of two phases of U phase and V phase are connected to the AC power source 10 without causing a rush current, and at the time when a voltage to a neutral point G of a common connecting point N is equal to a W phase voltage EW of the three-phase AC power source 10, a W phase negative direction thyristor NW is ignited, and a W phase capacitor CW is also connected to the AC power source 10. Thereafter, when a gate signal is applied continuously to all the thyristors, the positive and the negative thyristors of each phase conduct naturally in accordance with the polarity of power supply voltages EU, EV and EW, and the capacitors CU, CV and CW remain connected to the power source.

Title: Head for dot printer
Inventor: YOSHIDA HITOSHI
IPC: B41J2/275
Filed: 1990-04-10
Abstract: PURPOSE:To restrain vibrations of a back stopper and to reduce noises produced from a head by a method wherein a vibration absorbing means where the square root of the mass/rigidity ratio is equal to the vibration frequency of an armature at the time of printing is provided to the back stopper. CONSTITUTION:A vibration absorbing means where the square root of the mass (m0)/rigidity (K0) ratio is equal to the vibration frequency (omega) of an armature 8 at the time of printing is provided as a vibration absorber 51 on a back stopper 55. The back stopper 55 holds the armature 8 at its waiting position and, at the same time, works for stopping the armature when the same is pushed back on the reaction of the printing. Therefore vibration energy is given to the back stopper when the back stopper collides with the armature that is being pushed back. This vibration energy is consumed by vibratory leaf springs 53 of the vibration absorber 51. The vibration produced by the leaf springs releases less energy to the outside in the forms of noises unlike the vibration of the back stopper 55. Therefore the device can be made in such that gives comfortable environment for the operation with less noises.

Title: Phase comparison system
Inventor: SAITOU FUMIHIKO
IPC: H03L7/089
Filed: 1983-05-31
Abstract: PURPOSE:To realize a stable PLL circuit without decreasing the response speed against phase fluctuation by fixing a signal advancing the phase so as to control a signal delaying the phase. CONSTITUTION:A phase advance circuit 7 is triggered by an input signal Fi to feed a pulse Fi' having a prescribed pulse width Ti to a charge pump as a signal advancing the phase of an output signal F0, a phase lag circuit 8 compares the phase of the input signal Fi with that of the output signal F0 of an RLL circuit to feed the result to the charge pump as a signal delaying the phase of the output signal F0. Thus the charge pump conducts the operation repeating the transmission and absorption of electric charges at all times and responds instantly when there is a phase shift between the input signal Fi and the output signal F0. The charge pump keeps operation even at the synchronism, neither the response to the phase shift is unsharpened nor the response speed of a control voltage by it is lowered.
