Title: Differential speed arithmetic method for four-wheel steering type automated guided vehicle
Inventor: CHINBE HIROSHI
IPC: B62D7/14
Filed: 1994-10-25
Abstract: PURPOSE: To enable stable traveling and to improve the accuracy of following to a leading guide by providing an automated guided vehicle, which can independently drive four wheels, and calculating differential speed with the speed of that driving wheel as the function of steering angle of two wheels for which following control is performed by the leading guide. CONSTITUTION: Since the truck of the automated guided vehicle is traveled along a leading guide 2, steering angles ϕ3 and ϕ2 of right side traveling wheels are respectively controlled to be changed by a driving motor so that deviation amounts δ3 and δ2 from the leading guide 2 can be '0' by a guide sensor integrated with the right front wheel and a guide sensor integrated with the right rear wheel. Next, steering angles δ1 and δ4 of the left side wheels are decided to be orthogonal to rotation radius ρ1 and ρ4. Thus, since the four rotation radius orthogonal to the arbitrary steering angle of all four traveling wheels are gathered to one point C, respective traveling wheel advancing direction V1-V4 are orthogonal to the respective rotation radius and side slip on the ground to travel the carrier can be minimized.

IPC: G01L9/16
Filed: 1988-11-15
Abstract: PURPOSE:To make it possible to detect pressure highly accurately by using a piece of amorphous wire having high permeability as a magnetic core. CONSTITUTION:Inlet ports 1a are connected to paths for fluid. The fluid enters through the inlet ports. When the pressure of the fluid is changed, a pressure sensitive part 4 is displaced. A magnetic core 3 comprising a pipe 5 and a piece of amorphous wire housed in the pipe 5 is displaced by said displacement. When the fluid flows through the right inlet port 1a, the displacement of the magnetic core is increased in the + side. When the fluid flows through the left inlet port 1a, the displacement of the magnetic core 3 is increased in the - side. When the fluid pressures are applied from both right and left sides, the core is displaced in proportion to the pressure difference. A diaphragm is used for the pressure sensitive part 4. In this way, the pressure can be detected highly accurately.

Abstract: PURPOSE:To minimize the range of power interruption required for maintenance work by feeding load current intermittently from an intermittent load unit connectable with an arbitrary receptacle to a branch breaker on the distribution board side and then detecting a branch line, on which the current flows intermittently, by means of a galvanometer on the distribution board side. CONSTITUTION:Plug terminal 7 of an intermittent load unit 2 is plugged into a desired receptacle 5. Contacts are then switched with a timing set by a multi- timer 4 thus connecting/disconnecting the intermittent load unit 2 with/from a power supply at a predetermined time interval. Consequently, a load current flows intermittently into branch breakers 21, 22...2N in a distribution board 10 at a predetermined time interval. Load currents flowing on the branch lines of the branch breakers 21, 22...2N are then measured by means of a galvanometer 1 on the distribution board 10 side. When a branch breaker in the distribution board 10 corresponding to a desired receptacle 5 is measured, indication on the ammeter 12 of the galvanometer 1 varies at a predetermined time interval and thereby a target branch breaker can be specified under live state.
