Title: Automatic tracking device
Inventor: SAKAMOTO HITOSHI
IPC: G11B5/588
Filed: 1984-02-13
Abstract: PURPOSE:To reduce the drop-out of a head reproduction signal and the impulsive noise of a head displacement detecting signal, by multiplying an amplitude change component signal of the head RF output by a head displacement signal after binary coding both signals. CONSTITUTION:The amplitude of the RF output (a) of an amplifier 26 is varied by frequencies. The output of an envelope curve wave detector 28 is supplied to a BPF30, and only the amplitude change component is extracted. The output (b) of the BPF30 is converted into the 1st binary signal C by the 1st comparator 40. In the same way, the output (d) of a BPF22 is obtained by deleting an undesired low band component out of the output of an STG16 and converted into the 2nd binary signal (e) by the 2nd comparator 42. Both signals C and (e) are supplied t to an EX-OR44 serving as a multiplier for operation. At such a binary coding process, the drop-out amplitude to the waveheight of a noise pulse are reduced down to a level equivalent to the amplitude change component of an RF signal or a head shift signal.

Title: Detecting method for induction motor of defective phase
Inventor: TANAKA MASANORI
IPC: H02K11/00
Filed: 1980-02-29
Abstract: PURPOSE:To provide rapid protection for the wound rotor type or squirrel cage type induction motor by a method wherein sound generated by the motor in operation is detected and subjected to frequency discrimination and a secondary circuit phase defect is discovered when the amplitude of a certain frequency component is larger than the predetermined level. CONSTITUTION:A microphone 2 is located near the induction motor 1 to collect the sound the induction motor 1 generates while in operation. The detected signal travels across the amplifier 3 and LPF4 and is coverted into a signal of a specified frequency range. The LPF4 output is then compared for its amplitude to the reference level E in the comparator 5. When the amplitude of the LPF4 output is larger than that of the reference level E, the comparator 5 transmits a signal across FF6 and energize the warning unit 7. A phase defect in the induction motor 1 generating a sound of certain frequency due to torque pulsation known as Go rges phenomenon, proper frequency setting in the LPF4 enables the rapid detection of a phase defect.

Title: Relay driving circuit
Inventor: HIGUCHI TOSHIHIRO
IPC: H01H47/00
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce the heating of a relay by providing a resistor connected in series to a coil and a capacitor connected to the coil in parallel to the resistor. SOLUTION: When a driving transistor 3 is ON, charges are accumulated in a capacitor 4-1 with the lapse of time, and the voltage applied to a coil is gradually reduced from a rated voltage. However, since the voltage of an operable voltage or more is applied to the relay for the operating time or more, a contact is closed. Thereafter, the voltage applied to the relay 1 is further reduced, and the voltage of the rated voltage proportionally distributed to the internal resistance of the coil and the resistance of a resistor 4-2 is finally applied to the coil. However, since the resistance is determined so that this voltage is higher than the voltage for returning the relay 1, the relay 1 is never returned. Further, the power consumption is reduced by reducing the voltage, and the heating value is consequently reduced.
