IPC: H03J5/24
Filed: 1990-10-11
Abstract: PURPOSE:To reduce the noise figure(NF), gain deviation, image disturbance, etc., at the time of receiving high bands so as to improve various kinds of characteristics by supplying power for high band to a switching diode not through a resistor, but a tuning coil exclusively used for high bands only when the high bands are received. CONSTITUTION:One end of a tuning coil L5 exclusively used for high bands is connected to the anodes of 1st and 2nd switching diodes D2 and D3. In addition, the one end is connected to the cathode of a 3rd diode D4 and, at the same time, the other end is grounded through a capacitor C5. In this input turning circuit 3, the diodes D2 and D3 are turned on by supplying power BH for high bands to the coil L5 at the time of receiving high bands. Consequently, the voltage V1 across the connecting point of the cathode of the diode D1 and coil L1 of an FM trap circuit 2 can be raised to a sufficiently high level. Therefore, the NF gain deviation can be improved by about 1 dB and image disturbance ratio can be improved by about 4 dB at the time of receiving high bands.

IPC: A63B53/04
Filed: 1991-09-30
Abstract: PURPOSE:To displace the sweet spot of a club head toward the toe thereof, and enable the trajectory of a golf ball to be effectively corrected by dividing a head body into a soft head section at the toe and a heavy head section at other areas, and forming the breadth of the head body to be relatively large over a range from a toe section to a heel section. CONSTITUTION:A golf club head is divided into a head body H for a wood club, a soft head section LH at a toe, and a heavy head section HH at other areas. In addition, a different type of material with different specific gravity is, for example, used for each section to obtain approximately the same weight as a conventional club head. According to this construction, the width l of the head over a range from a toe section to a heel section can be made larger than the width l' of a conventional club head, thereby enabling a player to feel as if a sweet spot I.P is shifted toward the toe. Also, the trajectory of a golf ball stroked with the cub head can easily corrected toward a straight flight line via the gear effect of the head.

Abstract: PURPOSE:To prevent a motor with power source by means of a three-phase power supply from reversing and causing an unforeseen accident by comparing a phase difference value between two waveform shaping signals obtained by shaping two-phase voltage waveforms taken out from power given to the motor with a normal phase difference value. CONSTITUTION:A waveform shaping circuit 21 gives square-waved signals 21A, 21B obtained by shaping two-phase voltage waveforms of a given detection input l2C to the input-output port 24 of CPU 25. Then, the phase difference value between the square-wave signals 21A and 21B is processed by comparison operation by means of a reference value and CPU25. When the phase difference value is within the range of the reference value, a normal signal 25A is given to an operation controller 400 and to a closing circuit 12 so that three-phase power 300 is given as driving power l2B to a motor 200. Also, when the phase difference value is outside the range of the reference value, a phase abnormal signal 25B is given to the phase-changing circuit 11 of an input controller 1 so that predetermined phases are switched and the driving power is changed to positive three phases.

Abstract: PURPOSE:To suppress an excess of control, at the time of controlling an inverter frequency to move a load, by reversing an input signal to an effective power regulating means after the completion of the movement of a load and by making the input signal quantity larger than that before the inversion of polarity. CONSTITUTION:A switch 21 is closed when an inverter 1 closes a switch 4 during a supply of power. At the time of the movement of a load, the frequency of the inverter 1 is lowered, the corrected quantity of the frequency is inputted to a regulating circuit 15, the output of the regulating circuit 15 becomes a frequency-lowering signal by V/F converter 16 to lower the output frequency of the inverter 1, and the electric current of the inverter 1 decreases gradually so that the corrected quantity of the current becomes zero. However, when the output of the regulating circuit 15 is retained, power flows backward after the output of the inverter 1 became zero. When the polarity of the corrected quantity is inverted by the reverse power, the frequency rises with a large restoring force.
