Title: Torque controller for brake tester
Inventor: INAMURA JUNZO
IPC: G05D17/00
Filed: 1984-11-20
Abstract: PURPOSE:To control a stop speedily and to test braking performance securely by providing a means which holds continuously a hydraulic controlled variable right when the detected value of the number of revolution detector for a brake decreases almost to zero. CONSTITUTION:A rotating drum is braked with set torque through hydraulic operation and the time up to the stop of the drum is measured. At this time, the hydraulic pressure is controlled by a torque control amplifier 6 and hydraulic control amplifier 8 so that the set torque is obtained. When the set torque begin to be applied in a brake test, the number of revolution decreases and the detected value of the number of revolution detector 24 for the brake becomes a zero set value OSET. This is detected by a comparator 25 and inputted to a memory 26. When the detected value of the detector 24 becomes the set value OSET, the limited hydraulic pressure right before the detection is applied continuously to perform stop control over the drum speedily. The hydraulic pressure is controlled when the number of revolution is almost zero, so an abrupt rise in hydraulic pressure is suppressed and the drum is rotated at the same drop rate, thereby taking the test accurately.

Abstract: PURPOSE:To increase pressure resistance at low cost by providing a laminated pipe consisting of a plurality of laminated tubular layers which are formed spirally into a linear member and arranged closely to each other in a laminated form with the specified apparent modulus of elasticity of each tubular layer A, B. CONSTITUTION:A laminated pipe 11 consists of steel pipe 12 as a tubular layer and a reinforcing layer 13 which is laminated in the steel pipe 12 in such a manner that the reinforcing layer may have the same axial line as the steel pipe 12. The outer diameter L13a of the reinforcing layer 13A is smaller that the inner diameter L12b of the steel pipe 12A, so that the reinforcing layer 13A which is a material for the laminated pipe 11 can be inserted into the steel pipe 12A quite easily. When an assembly 19 is inserted into a die 23 of drawing dies 21, the diameter of the steel pipe is reduced by the die 23 and thereby the steel pipe 12 and the reinforcing layer 13 are adhered tightly to each other. Thus the laminated layer 11 with a significantly increased pres sure resistance is manufactured. In addition, the modulus of the reinforcing layer 13 is smaller, as compared to that of the steel pipe 12. Consequently, the laminated pipe 11 has an improved pressure resistance as the tension of its internal wall is dis persed in a radial direction and equalized.
