Title: Mounting device
Inventor: MATSUKI TAKAMASA
IPC: G12B9/04
Filed: 1988-03-11
Abstract: PURPOSE:To mount and dismount a cover which covers the side face of the housing without holding the cover by hand by providing means which are to be engaged and are provided to project to the side wall of the housing and engaging means which engage with the means to be engaged to the cover. CONSTITUTION:Hook parts 2a, 2a are first inserted into long holes 3a, 3a of a fitting 3 and the cover 2 is hooked to the fitting 3. The cover 2 is fixed near to the prescribed mounting position and screw holes 6, 6 in the lower part of the cover 2 are approximately mated with the position opposite to supporting parts 5, 5 of the housing 1. The cover 2, therefore, stays put without being removed or dislodged even if the cover 2 is not held by hand. In addition, there is no need for mating the screw holes 6, 6 of the cover 2 and the screw holes of the supporting parts 5, 5. The mounting of the cover 2 to the housing 1 is completed when the lower side of the cover 2 is fixed by screws 7, 7. The screwing operation is thus carried out without holding the cover 2 and the workability is thereby improved.

When the voltage fed to the constant current circuit 5 is detected at the detection circuit 8 and fed to the control circuit 9, the ON-OFF control of the switching circuit 7 is made in response to the detected signal, and when the DC current is ON or OFF, the average current changes, the current is smoothed with the smooth circuit 6, it is made constant at the next constant current circuit and fed to the subscriber line from the coupling circuit 4. Further, taking the ON time shorter and OFF time longer, the average current is small and the voltage fed to the constant current circuit 5 can be taken as less the specified value.

Filed: 1986-03-13
Abstract: PURPOSE:To excellently operate a pulse frequency modulation circuit by releasing the continuous level state and bringing the state into the normal state even when a frequency modulation pulse is a high or a low level consecutively and its operation is stopped. CONSTITUTION:A current source 1 causes a current proportional to the amplitude of an input signal to flow to discharge the electric charge in a capacitor C, and a comparator 2 detects the voltage across the capacitor C to output a pulse setting a monostable multivibrator circuit 3 when the voltage is a reference voltage VREF or below. The circuit 3 outputs a pulse of a prescribed width tau, a switch circuit 4 closes the circuit 3 by the time tau equal to the pulse width and a constant current source 5 charges the capacitor C. Then the output level of a pulse frequency modulation PFM of the circuit 3 is averaged by an averaging circuit 6 and the level is compared with the reference VREF1 or VREF2 by a comparator 7 or 8. The comparator 7(8) detects whether the output of the circuit 6 is a consecutive high or low level respectively, a reset circuit 9 or a set circuit 10 controls the circuit 3 causing the consecutive level to be released and bring the state to the normal operation.

Abstract: PURPOSE:To ensure an assured defeating action, by supplying the voltage increasing with the time constant to a series circuit of a constant voltage diode and a resistance when the power source is applied and actuating a working circuit only when the constant voltage diode conducts. CONSTITUTION:For the output of the feedback transformer 9 of a TV picture receiver, a low-voltage power source is supplied to the voice circuit 10 via the rectifying/smoothing circuit 8. This voltage is reduced down to the 1st voltage through the voltage stabilizing circuit 11 and supplied to the AFC circuit 12 and circuit 10. At the same time, the output voltage of circuit 8 is supplied to a series circuit of constant voltage diode ZD13 and resistance 14 and then connected to the working control terminals 20 and 21 of circuits 10 and 12 respectively from the joint of ZD13 and resistance 14 and via diode 15 and resistance 17 or D16 and resistance 18. The ZD13 is set so that is conducts with the 2nd voltage higher than the 1st voltage. The output of power source applying circuit 8 rises with a time constant, and D15 and D16 conduct during nonconduction of ZD13 to make the circuits 10 and 12 inactive. Then D15 and D16 are cut off with conduction of ZD13, and thus circuits 10 and 12 work.
