Title: Method for deciding traveling form of self-traveling vehicle
Inventor: NOGO HIDETOSHI
IPC: G06F19/00
Filed: 1987-04-23
Abstract: PURPOSE:To automatically decide the traveling form of a self-traveling vehicle by using the map data storing the traveling environment as a map to decide the traveling environment around the route points and deciding the traveling form of the vehicle based on the decided traveling environment. CONSTITUTION:A traveling form is decided from the map data 2 storing the traveling environment of a self-traveling vehicle 1 and based on the flag state of the traveling environment around a route point Pn. When a pass flag shows '1', the vehicle cannot pass the route of the point Pn. Thus a CPU 3 discontinues the search of the routes following said unpassable route and returns to a point preceding by one point to search another route point. While a decided traveling form is stored into the route data 4 together with the coordinates of the point Pn in case a traveling form is decided with a flag '0'. Then the CPU 3 gives a command to the vehicle 1 via a radio interface 5 for the data 4a stored in a memory 4 after all data on the route between the given start and end points are obtained. Then the vehicle 1 travels between given route points in a designated traveling form.

Title: Heating facility for molten steel metal
Inventor: SHINODA TSUYOSHI
IPC: H05H1/36
Filed: 1994-04-15
Abstract: PURPOSE:To reduce the quantity of arc deflection and reduce the partial abrasion of an electrode by electrically connecting cables from a plurality of electrodes on molten metal side to each arc electrode through molten metal so that currents may cross each other within the molten metal. CONSTITUTION:Cables are electrically connected so that the current from one electrode on molten metal side to one plasma torch or an arc electrode through molten metal 5 and the current from the other electrode 6 to the other torch 2 or arc electrode through metal 5 may cross each other within the metal 5. Here, though the two arcs 9 receive attraction, but it receives force in the opposite direction to the electrically corresponding electrode by the flow of the current shown by an arrow, so it becomes repulsion. Accordingly, it works in the direction where the attraction and repulsion offset each other, so it reduces the force to deflect the arc 9 as the sum total. Moreover, since two electrodes 6b are connected, in the case that the electric circuit is viewed from the torch 2 or the arc electrode, it becomes the same as it is equipped with two electrodes 6, so the amount of arm deflection decreases the same as in the time of one piece.

Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide low resistance and to prevent shorting between electrodes by providing outer connection electrodes on both surfaces of a first conductivity type semiconductor substrate. SOLUTION: Aluminium is vapor-deposited on both surfaces of an N-type semiconductor substrate 2 and a first electrode 8 and a second electrode 10 are installed by plating processing and the like. Outer connection terminals are connected to the first and second electrodes 8 and 10. When the thickness of the N-type semiconductor substrate 2 is set to be L, the area of the first electrode 8 to be S and specific resistance to be ρ, a resistance value R between the first and second electrodes 8 and 10 becomes ρ×L/S. The specific resistance of the semiconductor substrate 2 is larger than that of metal or it can be controlled by impurity concentration and desired specific resistance can be obtained. Since the semiconductor substrate 2, is thin, semiconductor inductance becomes small and inductance can be reduced by enlarging the area of the electrode 8. Resistance with small inductance is obtained and the electrodes 8 and 10 are arranged on both surfaces of the semiconductor substrate 2. Consequently, a part between the electrodes 8 and 10 is prevented from shorting.
