摘要： PURPOSE:To utilize the space of a material yard effectively by forming a load detecting means, a material soil-discharge position detecting means conducting detection as a material soil-discharge position and a material soil-discharge control means carrying out material soil discharge. CONSTITUTION:An induction line 2 is laid along a predetermined traveling path, on which a car 1 travels, a magnetic field generated from the induction line 2 is detected by a pair of pickup coils 3 mounted on the car 1, and the car 1 is steered and controlled. A command, by which a material is shifted from an upper floor Z1 to an upper floor Z2, is received from a control room 10 through a wireless installation 6 for the car 1, the head pressure and bottom pressure of a bucket cylinder are detected by a working-machine hydraulic sensor 23 and the rolling angle, etc., of a car body by a sensor 27 for detecting the inclination of the car body respectively in the course of the transport along the induction line 2, and a position, where the load applied to a bucket reaches a specified set value or more, is used as the position of the discharge of the material. The material is not discharged so far as the material does not collide with the bucket, and the material is discharged toward this side from the interior of the upper floor Z2.

摘要： PURPOSE:In a device for automatically transfering materials from a material yard into a hopper to form the material into a piled timber in a concrete plant or the like, to reduce labor required for works and to improve working efficiency by radio-controlling an unmanned working car which can freely run along an induction line. CONSTITUTION:Different kind of materials are accommodated in material yards Z1-Zn, and can be suitably transfered to hoppers H1-Hn provided at plural number of different positions by a wheel loader (vehicle) 1. An induction line 2 is laidly provided on a road surface where the vehicle 1 runs, and the lateral slippage of the vehicle 1 from the induction line 2 is determined on the output of a pair of pickup coils 3 provided on both the sides of the body of the vehicle 1 to control the steering of the vehicle. In addition, the vehicle 1 is provided with a radio transmitter 6 for radiocommunicating with a radio transmitter 11 provided in a command section 10. Various kind of commands sent from the command section 10 are inputted into a controller mounted on the vehicle, and an engine accelerating command and a working machine command are generated on an inputted command and the output of various kind of sensors to control the operation of the vehicle 1.

摘要： PURPOSE:To improve the memory efficiency by listing up the operations conducted by an operator, dividing these operations until no common operations are available, and storing a basic operations pattern program as the divided results in the memory, thereby making use of the stored memory in controlling the vehicle. CONSTITUTION:Different materials which are loaded in three material storing parts U1-U3 are transferred and loaded to product receiving hopper H1-H3 as applicable by means of an operating vehicle 1 such as a wheel loader. In a transfer system where the vehicle l is automatically run through the communication with a commanding station, an on-vehicular automatic control device is provided with the memory which lists the operations conducted by an operator, divides these operations until no common operations are available, and stores the basic operations pattern program as the divided results. This on vehicular automatic control device allows the combination of a plurality of basic operations pattern programs according to this operating command to be prepared when the operating commands from the commanding station 10 are received and the relevant operations to be automatically conducted.

摘要： PURPOSE: To provide a freezing preventive pavement structural body which is easy to construct and excellent in durability and easy in maintenance control by installing a layer made of a conductive powderlike substance near the front surface of a pavement body and heating the surface of the pavement body by energizing this layer. CONSTITUTION: A conductive layer is installed near the front surface of a pavement body wherein the conductive layer comprises conductive carbon, a metallic powderlike substance, resin, asphalt, cement or the like which are mixed with a binder. The conductive layer is electric-wired by burying a terminal in the layer and so forth, thereby heating the front surface of the pavement body. This construction makes it possible to provide a freezing preventive road surface which is easy to construct and excellent in durability and easy in maintenance control.

摘要： PROBLEM TO BE SOLVED: To easily cope with an existing vehicle additionally to reduce cost, and to enhance followability of automatic steering by constituting a steering wheel and the like of a vehicle to be directly operated with a turn driving means such as a motor so as to perform the automatic steering. SOLUTION: In the case of automatic traveling, a pair of plate members 25A and 25B are turned to have the bent relation with a predetermined angle each other, and a motor pulley 23 is horizontally moved toward a steering wheel 22 to compressively contact the periphery of the steering wheel 22. In this condition, a pair of sensors disposed in the front of the vehicle, detect magnetic flux emitted from an induction line disposed on a load, and controlling signal for changing traveling direction of the vehicle is output from a controller to a motor. Thereby, the motor is turned toward a predetermined direction by predetermined turning amount, the steering handle 22 is turned toward the predetermined direction by predetermined turning amount to be steered with the turning of the pulley 23 by the predetermined turn amount in the prescribed direction, and the vehicle automatically travels along a predetermined route.
