Title: Traveling method for unmanned carrier
Inventor: ISHIDA HIROTERU
IPC: G05D1/02
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to change the course of an unmanned carrier traveling along traveling lines crossing at a large angle. SOLUTION: Whether a course change based on a traveling program is to be executed or not is judged, and when an address mark indicating a position for changing a course is detected, the right and left wheels of a traveling device are rotated mutually in reverse directions to rotate the traveling device by 90 deg. from the unmanned carrier (steps 210 to 214). In a state maintaining the rotational angle, front and rear traveling devices are traveled in the revese directions, so that the unmanned carrier is turned to change its advancing direction and traveled along the changed traveling line (steps 216 to 226). Consequently, the advancing direction of the unmanned carrier can be turned to an optional direction in narrow space.

IPC: H03B5/18
Filed: 1986-06-19
Abstract: PURPOSE:To extend the variable range of the oscillation frequency by impressing a voltage, which is changed reversely to the DC voltage, which is impressed to a varactor diode of a resonance circuit, based on a transistor (TR). CONSTITUTION:The output from a subtractor 22 is given to the base of a TR 21 for the purpose of changing the base potential of the TR 21 reversely to the change of a tuning voltage BT, and the base bias of the TR 21 is reduced and a voltage VCB between the collector and the base is raised when the tuning voltage BT rises. An input capacity Cob is reduced in this manner to raise a maximum oscillation frequency. If the tuning voltage BT is reduced, the base bias of the TR 21 is raised and the voltage VCB between the collector and the base is reduced to increase the input capacity Cob, thereby reducing a minimum oscillation frequency.

Abstract: PURPOSE:To prevent dust generation in respect of retractable spike tire by projecting spikes in the use of a hydraulic bag at the instant of slip, in stepping the brake pedal and operating the handle button etc. CONSTITUTION:Occurrence of slip causes a iron ball 18 mounted on a body to be actuated, a wire 16 to be drawn and a stopping iron 14a to be hauled, thereby, a lever 11 is moved to extend a instantaneous spring 8 for pressingly move a piston 7. Hydraulic pressure is thus supplied to a hydraulic bag 4c via a hydraulic pipe 5a, a shaft portion 5b and hydraulic pipes 4a, 4b to expand the bag. A spike 3, therefore, is projected to provide bite for an ice and snow 22 on road face. At this moment, an operating device is applied to a handle and associated with a brake pedal operation. Such a constitution permits occurrence of dust to be controlled and slip to be prevented.
