Inventor: WATANABE NOBUAKI
IPC: A01B59/043
Filed: 1987-11-06
Abstract: PURPOSE:To maintain accuracy of control of tilling depth, by keeping action amount of advance and retreat of feed back link mechanism unchanged even by adjustment of height of hanging of rear cover. CONSTITUTION:Rotation of a rear cover 40 is transmitted through a rotary arm 62 and an advance and retreat rod 72 to a pushing arm and further a hydraulic cylinder is controlled through a pressure receiving arm to control tilling depth. The rear cover 40 can be changed by operation of a change lever 55 from the upper position wherein a connecting arm 65 is upward rotated and a flexible film 41 is bent to the lower position wherein the connecting arm 65 is downward rotated and the flexible film 41 is expanded. Since the longitudinal position of a pivot pin 67 is unchangeably set, the position of the advance and retreat rod 72 will not change. Consequently, accuracy of control of tilling depth is not influenced even by fluctuation of the rear cover position.

Filed: 1990-10-19
Abstract: PURPOSE:To detect a minute angle by providing a signal processing part which supplies an alternating current to a detecting coil, and detects the change of the impedance of the detecting coil in consequence to the rotation of a magnet part. CONSTITUTION:Two input terminals of an astable multivibrator 41 are connected to each one terminal of detecting coils 33, and each of the other terminals of the detecting coils 33 is connected to a high potential power source E. Pulses are generated with a constant frequency in the astable multivibrator 41. A pulse current is fed to the collectors of transistors Tr1, Tr2. A signal magnetic field proportional to the cosine value of the rotating angle theta of a magnet part 2 is applied to each soft magnetic wire 32. Since this signal magnetic field is proportional to the cosine value of the rotating angle theta of the magnet part 2, the average of the currents at both collectors is proportional to the cosine value of the rotating angle theta and the currents include components of modulated currents of reverse phases. The components of the modulated currents are converted to emitter voltages Ve1, Ve2 by emitter resistances R1, R2. These voltages Ve1, Ve2 are shut in the high frequency band region thereof by an LPF 42, detected by a wave detecting circuit and output.
