Title: Traveling control method for unmanned carrier
Inventor: TABATA HIDEMITSU
IPC: G05D1/02
Filed: 1985-08-13
Abstract: PURPOSE:To suppress the fishtailing phenomenon and to stabilize the steering actions by increasing the deviation amount delivered from a route sensor which functions to reduce the reference speed delivered from a speed command circuit in accordance with the difference of torque between right and left drive means. CONSTITUTION:A comparator 21 delivers the steady signal S to a speed command circuit 22, a route sensor 23 and amplifying circuits 24 and 25 respectively when the output of a speed difference detector 20 exceeds a set level. When an unmanned carrier is driven a rectilinear route having no recess/projection an approximately equal torque is applied to the right and left motors 6 and 11 and no steady signal S is delivered from the comparator 21. Thus the gains of both circuits 24 and 24 are reduced. This suppresses the fishtailing phenomenon and stabilized the steering actions of the carrier. If one of both drive wheels rides on a recess/projections area of the route, the drive current produces a difference between both motors 6 and 11 and the signal S is delivered. As a result, the reference speed (v) given from the circuit 22 is reduced together with the increased deviation amount (v) of the sensor 23 and the increased gains of both circuits 24 and 25. Then the steering responsiveness is improved. As a result, the unmanned track is set back to its normal drive route.

Abstract: PURPOSE:To increase only the quantity of the intrusion of light to the n-type clad layer side having low resistivity without augmenting the distance of the intrusion of light to a p-type InGaAlP clad layer having high resistivity, and to reduce the optical density of an active layer by forming an optical guide layer between the active layer and an n-type clad layer. CONSTITUTION:Since an optical guide layer 12 having a refractive index higher than clad layers 11, 14 is formed brought into contact with an active layer 13, light is mainly wave-guided in the optical guide layer 12. Consequently, the optical density of the active layer 13 is made smaller than normal double hetero-structure having no optical guide layer having the same active-layer thickness by approximately forty %, and a COD optical output is increased by approximately one and a half times. Since the intrusion of light to the outside of the active layer 13 is extended to the optical guide layer 12 and n clad layer 11 side, the sum total of the thickness of the optical guide layer 12 and the clad layer 11 on the n side must be increased to 1.5mum in order to prevent the augmentation of absorption loss in a GaAs substrate 10.
