Title: Ringer circuit
Inventor: ICHIKAWA SHUJI
IPC: H04M1/00
Filed: 1995-04-17
Abstract: PURPOSE: To generate a ringer tone even from any kind of telephone set without increasing an oscillated frequency while realizing a ringer with less noise. CONSTITUTION: An amplified output of a transistor(TR) Q2 is fed back to its base to oscillate the TRQ2 . An output of output TRs Q3 , Q4 is a sine wave. When the sine wave oscillation output is fed to a circuit driving a ringer IC by rectifying and integrating the oscillation output, since a current waveform appearing between input terminals of a rectifier circuit is not a pulse but a sine wave, the fluctuation in the current waveform at the output of an integration circuit is reduced and its mean current is increased, resulting that the ringer IC is driven independently of a load (element constant of the integration circuit). A black telephone set can be driven.

Title: Protection method at shaft lock of dc motor
Inventor: HORIE HIDEO
IPC: H02P6/06
Filed: 1992-03-17
Abstract: PURPOSE:To suppress the heating at motor lock so as to prevent the burning of a motor by detecting the current flowing through a DC motor, and inputting this current value into an integration circuit equipped with a time constant much larger than the start time of a DC motor, and setting a current limit value so that it may be extremely small when the integrated value gets over the specified criteria. CONSTITUTION:Assuming that the current for starting a motor M in the case of starting the motor M in the condition that the motor M is locked is 3A and that the resistance value of a resistor RD for detecting the current of the motor is 1OMEGA, the potential at point A becomes 3V. Moreover, the potential at point B is determined by a resistor R1 and a capacitor C1. And an integration circuit AA has a time constant much larger than ordinary start time. Accordingly, if the motor M is started in locked condition, the potential at point B goes up gradually, and when it reaches soon the voltage where a transistor Q1 is turned on, this lowers the base potential of a transistor Q11 for power control, so only about 0.6A flows through the motor M. Hereby, the heating in the case where the motor is locked can be suppressed.
