Title: Steering gear for unmanned moving vehicle
Inventor: HASHIMOTO NAOTO
IPC: G05D1/02
Filed: 1985-03-22
Abstract: PURPOSE:To improve the run performance of an unmanned moving vehicle by providing a rear steering wheel with a stationary mode wherein the quantity of a shift on a linear run path is small and a nonstationary mode wherein the quantity of the shift is large or wherein a curved run is made. CONSTITUTION:The rear steering wheel 3 is directed in a leaving direction to a tape 9 as the reference line of the steering wheel 3 in the nonstationary mode and its steering angle is determined with the signal of a detector. In this mode, steering wheels 2 and 3 are in the direction narrowed toward the end, so its radius R of running is extremely small. Consequently, the wheels are converged on the tape 9 speedily on a linear run path. Further, a run with a small radius is made during a curved run. The steering wheel is directed to the tape 9 in the stationary mode and its steering angle is determined with the signal of the device 8. In this mode, the steering wheels 2 and 3 are in the same direction, so the radius R is relatively large. Consequently, the wheels are converged on the tape 9 slowly on the linear run path and large shifting is reduced, so that the unmanned moving vehicle becomes easy to run continuously within a small range.

Filed: 1992-02-07
Abstract: PURPOSE:To prevent short-circuit between a signal wire and a bus bar, by excluding wirings except bonding wires in the region between each bonding terminal and bonding pad which are connected by the bonding wires. CONSTITUTION:A bonding terminal 2C of a bus bar 2 and a bonding terminal 4a of a signal wire 4 are stuck on the upper surface of an IC chip 10 by using an insulative double-surface tape. A branching part 2b of a bus bar 2 is mechanically bent 180 deg. from above to the left and vertically overlapped so as to keep a distance (d). Thereby the main wiring part 2a of the bus bar 2 is arranged on the signal wire 4 so as to keep the distance (d) without coming into contact with the signal wire 4. Hence it can be prevented that a bonding wire comes into contact with the main part of a power supply line and generates short- circuit, without making a bonding wire loop for connection high. Thereby the reliability is improved, and a device can be thinned.
