Patent JP-S6123910-A (JP)
Title: Optical range measuring device
Inventor: KOBAYASHI KEIICHI
IPC: G01C3/06
Filed: 1984-07-12
Abstract: PURPOSE:To tape accurate range measurement without any influence of disturbing light even on an evil condition where there is much disturbing light by adding a projection period modulating circuit, reference volage setting circuit, difference detecting circuit, subtracting circuit, etc. CONSTITUTION:Projection light 24 from a laser diode 1 which is modulated by the projection period modulating circuit 13 is converted by a photodetection output voltage converting circuit 6 into a voltage. Its photodetection signal is supplied to discriminating circuits 14A and 14B, which discriminate between an output at a turn-on time and an output at a turn-off time. Those two outputs are passed through amplifying circuits 15 and subtracting circuits to obtain photodetection signals after disturbing light noises are separated. The photodetection signals are inputted to a range detecting circuit 10 and a photodetection quantity detecting circuit 18. A voltage (a) proportional to the quantity of photodetection is supplied to the difference detecting circuit 12, which detects the difference from a reference voltage (b) as the output of the reference voltage setting circuit 11. This difference is fed back to a light emission quantity control circuit 7 through the modulating circuit 13. A control circuit 7 controls the quantity of projection light on the basis of the difference voltage. Consequently, the quantity of photodetection is made constant regardless of the influence of disturbing light.

Title: Method for controlling winding speed automatically in tire bead molding
Inventor: CHO AGUN
IPC: B21C47/02
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To make a winding speed constant while a portion for one bead core is taken up by a winder in tire bead molding and to prevent the quality deterioration of a bead. SOLUTION: While a bead wire 1 coated with rubber is being fed downstream at a speed greater than a feed speed V1 by an accumulator 3 installed downstream from a pull roll 2 which gives a constant feed speed to the bead wire 1, the bead wire 1 is taken up at a constant winding rotational speed V1 by a winder 4. After that, with the rotation of the pull roll 2 continued, the rotation of the winder 4 is stopped at a prescribed winding position. Next, in a cutting/ taking-out process in which the bead wire 1 is cut and taken out from the winder 4, the movable pulley 6 of the accumulator 3 is returned to a starting position.

IPC: B41F7/32
Filed: 1986-06-23
Abstract: PURPOSE:To perform the composition management highly accurately by means of a small and easy-to-handle device, by providing an alcohol concentration detector, a temperature detector and a hydrogen ion concentration detector in order to detect the composition of moistening water being fed to a printing machine and to control the addition of specific solute into the moistening water on the basis of the detection result. CONSTITUTION:In case of an alcohol dampening system for an offset printing machine, a portion of moistening water being fed from a pump 2 toward a vessel 3 is taken through a bypass pipe 9 at a detecting section 8 of the device, then measured and returned through a pipe 10 to a moistening water tank 1. On the basis of signals fed from various sensors arranged at a detection section 8, a control section 11 calculates the temperature of the moistening water, the alcohol concentration and the pH level then controls such that the composition and the temperature of the moistening water converge to the levels preset by a digital switch based upon the detection result. Since all sensors necessary for control are collected in the detecting section 8, the structure is simplified and the handling is facilitated resulting in an almost completely automated control.
