Title: Pickup arm
Inventor: MATSUMURA ASAYUKI
IPC: G11B3/31
Filed: 1985-11-08
Abstract: PURPOSE:To suppress resonance of a pipe itself and to reproduce with high fidelity by inserting the first arm member into a groove or a through hole provided in the second arm member and filling a gel-like member in the gap of the two arm members. CONSTITUTION:A pipe 12 has tapered form and has outer diameter that can be incorporated inside of a pipe 11. After incorporating the pipe 12 inside of the pipe 11, a gel-like member 13 is injected into a space formed by the pipe 11 and pipe 12. In above-mentioned constitution, as the size and weight of the pipe 11 and pipe 12 are different, they are different in resonance frequency. Accordingly, when one pipe is resonating, another is not resonating, and an effect to suppress resonance is given. Further, as the gel-like member 13 is interposed between them, resonance is suppressed all the more. Thus, reproduction of high fidelity becomes possible.

IPC: H04M19/00
Filed: 1985-11-12
Abstract: PURPOSE:To prevent a silent reverse circuit from oscillation and to stabilize the circuit by arranging a silent reverse filter on the signal input side of a polarity inverting level shifting circuit and impressing a polarity inversion control signal and a reference voltage to the filter. CONSTITUTION:A two-wire (W) detector 11 detects a voltage V applied between chip rings and an AC cutting circuit 12 is driven to remove voice inputted from a telephone set 21 and to input only a DC component to a function generating circuit 13.

Filed: 1984-11-30
Abstract: PURPOSE:To prevent fluctuation of idling engine speed or engine stoppage, at the time of connecting an external load to an idling speed control equipment, by increasing engine speed to a specific level beforehand and then virtually allowing operation of load. CONSTITUTION:In an engine in which idling engine speed is adjusted to a target level by opening or closing a throttle bypass valve 6 installed in the sucked air duct, when an external load is connected to the engine, a load control switch 25 is turned on and load control signal ISs are thereby put into a control equipment 30, a target value for iding engine speed is computed on the basis of various operation parameters of the engine. The target value is set at such an idling speed that engine stoppage cannot occur even after an external load is added, and the external load is actually operated when the reaching of the idling speed to the target value is detected after the by-pass valve is opened. Likewise, the idling speed is reduced beforehand when the load is disconnected.
