Title: C position circuit of trunk circuit
Inventor: HASUMI TAKASHI
IPC: H04M7/00
Filed: 1983-11-22
Abstract: PURPOSE:To obtain a C position circuit while using an inexpensive miniature relay by charging discharging the second condenser by the output of the first detection circuit, inputting the discharge into a comparator, and driving a C position relay by the output of the second detection circuit. CONSTITUTION:When a dial pulse is sent out by changing a switch SWO OFF  ON OFF ON..., a charging current flows a condenser CC2. This charging current of said CC2 flows when SWO changes from on to off, therefore the minus input of a comparator CMO exceeds a plus input to which comparison voltage is added to. The excess makes a condenser CC3 discharge via a diode D1. Because the CC3 is made to discharge gradually by a resistor R6 placed between power sources, the CC3 does not add voltage exceeding the comparison voltage to the plus input of a comparator CM1. Therefore, the CM1 does not change and a trasistor Q0 continues on-state.

Title: Speaker system
Inventor: HARA KOZO
IPC: H04R1/02
Filed: 1986-09-17
Abstract: PURPOSE:To transduce an applied music signal into an acoustic energy with less loss by fixing a rear plate to a molding cabinet via an interposed substance having a different property from that of the cabinet in a speaker system formed by fitting the rear plate to the formed cabinet. CONSTITUTION:The interposed substance 6 having a different property from that of the cabinet 1 is adhered to the cabinet 1 by an adhesives at a position mated with a step difference fitted with the rear plate at the rear end of the cabinet 1. The rear plate 3 is screwed to the interposed substance 6 by a fixing screw 4 and a box is formed. When a music signal is inputted, the cabinet having weak strength tends to be resonated. Since the interposed substance 6 having a different property is fixed to the cabinet 1, the resonance hardly takes place because of the effect of attenuating the resonance by different kinds of materials. Thus, the music signal is transduced into an acoustic energy without being interferred by mechanical resonance, the music reproduction with high fidelity is attained.
