Title: Traveling controller of carrier truck
Inventor: SASAKI KO
IPC: G05D1/02
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To smoothly perform the steering of a carrier truck by controlling the brake force of one drive wheel in accordance with the speed of the carrier truck. SOLUTION: When three traveling sensors 10A to 10C detect that a traveling path is curved, a control part 20 control both drive motors M1 and M2 so that smooth steering can be performed along a set traveling path. That is, a steering angle calculating part 40 recognizes a steering angle by calculating the difference between the revolving speeds of both motors M1 and M2 based on the difference of voltages of both tacho generators(TG) 32A and 32B, and the part 20 controls the revolving speeds of both motors M1 and M2 so that the steering angle may not exceed a fixed value.  A power generation braking control parts 34A and 34B set the optimum resistance value so that the optimum brake force can be given to a drive motor to which conduction is cut off so that smooth steering can be performed along a traveling path at a currently traveling speed and makes a resistor of the resistance value consume voltage that is generated by the drive motor.

Filed: 1987-12-10
Abstract: PURPOSE:To decrease the rate of generation of a defective picture element based on a disconnection and a short circuit of a connecting film by covering completely the surface, especially, the side face of a display driving element with an insulating film. CONSTITUTION:In a metallic film forming process, a metallic film 3 under an amorphous silicon layer is formed by a pattern containing not only a place where a display driving element 40 is to be provided but also its peripheral part. Accordingly, in the next display driving element forming process, after the amorphous silicon layer 4 has been grown and the display driving element 40 has been formed in a prescribed place on the metallic film 3 by its dry etching, it is unnecessary to perform etching to the metallic film 3 of its peripheral part. In an insulating film forming process continued from said process, an insulating film 6 is stuck so as to cover at least the display driving element being free from undercut and its peripheral part. In such a way, when a metal crush as aluminum, etc. has been stuck onto the insulating film 6 in the next connecting film forming process, it does not occur that said metal is disconnected in a rupture part of the insulating film 6, or short-circuit to the lower side part of the display driving element, and the probability for generating a defective picture element in a display panel is decreased remarkably.

CONSTITUTION:A radio receiver comprises a synchronizer A, a high frequency amplifier B, a wave detector C, a low frequency amplifier D, a power amplifier E, an output part, etc., and frequency graduations are changed over to BC band, SW band, FM band, etc., before the operation of a DC motor, and the intensity of electromagnetic waves is read with a volt meter. And, a wireless set is adjusted so that the intensity to each frequency may be lowest. Next, the DC motor is operated to examine the electromagnetic waves, and in the case that the change of the electromagnetic waves is small, it is diagnosed that an armature is normal. Moreover, if the change is large and the frequency distribution is specified, it is diagnosed that it has deteriorated. As a result, the maintenance required at proper period becomes possible by investigating and monitoring the situation of the deterioration from outside the DC motor periodically.
