Title: Steering control unit in crawler-type mobile farming machine
Inventor: OTSUKA KOJI
IPC: A01B69/00
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide the subject steering control unit designed to quickly perform a one-side-braked turn with small turning radius by making a steering lever fall deeply during turning by selecting one-side speed-reducing turn mode. SOLUTION: On tilting a steering lever e.g. left by one-side speed-reducing turn mode, a left lever direction-detective switch and a lever tilt angle sensor give signals to a controller, which, in turn, actuates a reverse/speed reduction changeover clutch 66 to perform a speed reduction driving on a left crawler to effect turning left. At this time, when the steering lever is further tilted in a large way, the lever tilt angle sensor detects this movement, and the clutch 66 is let out by a turn mode automatic changeover means integrated into the controller, setting a brake 9 in motion. Thereby, quick transfer from the one-side speed-reducing turn mode to one-side braked turn with small turning radius can be accomplished by a simple operation by such a simple operation as to merely making the steering lever fall, thus enabling a desired course to be changed quickly and safely through avoiding dangers.

Abstract: PROBLEM TO BE SOLVED: To provide a device which can be used easily by everybody and by which the leak place of a fluid can be inspected and detected surely. SOLUTION: A leak-place detecting device is constituted as a movable probe 10 which supports two or more sound-wave detectors by keeping a constant distance. Output signals from the sound-wave detectors 11a, 11b are passed through an adaptive filter, they are converted into digital signals by an A/D converter, a cross-correlation function is numerically calculated by a DSP on the basis of the digital signals, and the direction of a leak point is judged so as to be displayed on an LED display 14. The cross-correlation function is computed by an FFT method, the Blackman-Chewkey method or the like. When the sound-wave detectors are brought into contact with a pipe or a can body having a leak, an LED display device in a direction close to a leak point is turned on, and the probe is moved to the direction. When an LED device in the center is turned on, it indicates that a leak point exists between the sound- wave detectors.
