Title: Switching power supply protection circuit
Inventor: KURODA EIJU
IPC: H03K17/08
Filed: 1986-06-13
Abstract: PURPOSE:To obtain high immunity from external noise to the operation of a titled circuit by controlling the cut-off of a main switching transistor (TR) by a TR to eliminated the need for a latch circuit. CONSTITUTION:The latch circuit is eliminated to directly drive a TR 10 by an output of comparator 5, a power voltage Vcc is supplied to a power voltage drop detection circuit 70 in place of the output of a latch circuit driving a TR 17 to detect the drop of the power voltage Vcc and its detection output is used for the control. If the short-circuiting of a load takes place, the potential of a capacitor 41 rises and if it exceeds the reference voltage of a reference voltage source 22, the TR 10 is electrified to cut off the output of the comparator 2. Thus, even if the short-circuit state of the load is released, the output of the comparator 4 remains at a high level and the capacitor 41 keeps the state charged by a power voltage. Thus, the electrified state of the TR 10 is maintained and the output of the comparator 2 keeps the off-state.

Title: Telephone set
Inventor: SATO KAZUMI
IPC: H04M1/00
Filed: 1988-06-03
Abstract: PURPOSE:To inexpensively secure the safety of a caller by means of a simple circuit by providing a sound volume adjustment means and a sound volume control circuit reducing the sound volume of an earphone input when there is a ringing tone and setting it to a normal call level when the ringing tone stops. CONSTITUTION:If there is a sudden incoming call and there is the ringing tone in a reception sound line 1 when a receiver is waiting for the incoming call by an earphone 5 at the time of a waiting state, a ringing tone detection circuit 10 detects it. The sound volume control circuit 102 operates a variable attenuator 103, and controls the sound volume inputted to the earphone 5 to a level without pain through an amplifier 2 and a switch 3 since the earphone 5 is connected through the switch 3 and a sense line 104. Next, it is controlled that a pleasant reception is executed by returning the attenuator 103 to an original state and reducing an attenuation quantity when it comes to a call state by the off-hook of the receiver and the like. That the attenuator 103 is attenuated until the ringing tone is inputted to the line 1 avoids a moment leaking output from the earphone 5 due to the detection rise and delay of the circuit 101 and that of the circuits 102 and 103 as the operation of the circuit 2.
