Title: Signal processor
Inventor: FURUHATA TAKASHI
IPC: H04N5/922
Filed: 1986-05-30
Abstract: PURPOSE:To improve the S/N of a signal and waveform distortion by adopting the constitution that the 1st and 2nd basic circuits having a transfer function approximated by a specific function are connected in cascade to form a basic circuit and a means is used to form the titled unit combining the input signal via the basic circuit and the input signal not through the basic circuit in a prescribed ratio. CONSTITUTION:The 1st basic circuit 10 has a transfer function approximated by functions expressed in equation 1 or 2, where omegais an angular frequency of an input signal, T is a constant having the unit of time, and (k) is a constant. The 2nd end basic circuit 20 is constituted by connecting time axis conversion circuits 200, 300 before and after the circuit 10 in cascade. The circuits 10, 20 are connected in cascade to constitute the basic circuit 100. The input signal Si through the circuit 100 and a coefficient device 33 and the input signal not through them are added by an adder 34 and the said both signals are combined in a prescribed ratio to obtain an output signal So. Thus, a pre-emphasis circuit whose phase characteristic is linear emphasizing the amplitude of the signal at a middle or a high frequency and a de-emphasis circuit having an opposite amplitude characteristic to the amplitude characteristic of the pre-emphasis circuit and whose phase characteristic is matched with the said circuit over a wide frequency range are realized in this way.

IPC: F02D1/04
Filed: 1986-05-29
Abstract: PURPOSE:To aim at stabilizing the rotational speed of a Diesel engine at a low rotational speed, by making the fitting section of a tension lever concentric with the center axis of a governor lever, and by making the fitting section of a governor lever eccentric from the center axis of the governor lever. CONSTITUTION:A pair of right and left bearings 4 are rotatably fitted on a governor lever shaft 17, and are formed with tension lever fitting sections 41 concentric with the governor shaft 17 and governor lever fitting sections 40 which are made to be eccentric toward the side remote from a shifter 26 adapted to receive governor force. Further, governor levers 7, 9 are rotatably fitted on the fitting sections 40, and a tension lever 8 is secured to the fitting sections 41. With this arrangement, when a governor lever is rotated relative to the tension lever during low speed operation, the governor lever is rotated about the center axis of the fitting sections 40 so that the lever ratio of the governor is small. Accordingly, it is possible to effectively use governor force to enhance the rotational stability of the engine.
