Title: Yarn breakage detection method for doubling winding
Inventor: TATEFURU SHIROU
IPC: B65H63/036
Filed: 1984-02-15
Abstract: PURPOSE:To reliably detect all cases of yarn breakages in the whole yarn path with one detector by disposing a yarn eveness detector in a traverse area and detecting that at least one yarn is broken before doubling due to an output of the detector accompaning with the incoming and outgoing of the yarn. CONSTITUTION:Every time reaching the traverse end, the yarn enters a detection groove 8a of a yarn evenness detector 8. At every such moment, a pulse signal 0 is output from the yarn evenness detector 8. The detector 8 is adapted to output a signal proportional to the thickness of yarn Y or its variations, so that the crest value V1 of the output signal 0 is proportional to the thickness of yarn Y. For example, if one yarn before doubling is broken at a time tB, the crest value is V2 which is a half of the crest value V1 in the normal condition. Accordingly, the output signal 0 is guided to a comparator 9 to be compared with a preset value VC, and if one or more yarns before doubling are broken, a yarn breakage signal B is output from the comparator 9. Thus, due to one time of yarn breakage detection, various yarn breakages caused in the whole yarn path of the yarn doubling equipment can be detected effectively.

IPC: H02J15/00
Filed: 1984-02-15
Abstract: PURPOSE:To suppress overvoltage and low voltage at a current changing point of the 2nd superconductive coil by feeding back the variation ratio of a capacitor voltage to a voltage control circuit. CONSTITUTION:The 1st superconductive coil 3 for energy accumulation is charged with energy by a DC power supply 1 and then a switch 2 is opened to circulate current through semiconductor switches 4, 5 and diodes 6, 7. Under said condition, energy is transferred from the 1st superconductive coil 3 to the 2nd superconductive coil 13 for load while controlling the 1st and 2nd chopper circuits 22, 23. In this case, a voltage variation detecting ratio detecting circuit 24 having a differential element and an arithmetic circuit 25 are added and a current supply ratio D1 is calculated from the variation DV of the capacitor voltage Vc by the circuit 25 and inputted to a current supply ratio control circuit 20. Consequently, energy excessively charged from the 1st chopper circuit 22 to a capacitor 8 can be suppressed to a low level immediately after the transfer of current from the 2nd superconductive coil 13 to a flat part.

Abstract: PURPOSE:To increase the number of picture elements effectively without providing fine structure and high density arrangement of a CCD by a method wherein, when a plurality of gate electrodes are biased at a required potential selectively, corresponding light sensing regions are connected to an output diode through inversion layers and optoelectric transducing signals are outputted from corresponding parts of the CCD. CONSTITUTION:An infrared detector 1 is composed of a plurality of gate electrodes 7 which are electrically isolated from each other and define respective light sensing regions individually and an output diode 9 which is provided in common for the respective light sensing regions. If one of the gate electrodes 7 is biased at a required potential, an inversion layer 13, i.e. an opposite conductivity type layer, is formed in a one conductivity type semiconductor substrate surface immediately below the biased gate electrode 7. The opposite conductivity type layer 13 is connected to an opposite conductivity type region 6 of which the diode element 9 is composed and the depletion layers 14 of both the layer 13 and the region 6 are unified. As a result, only the part immediately below the biased gate electrode 7 operates as a light sensing region. Therefore, by applying the bias potential to the respective gate electrodes 7 successively, the parts immediately below the respective gate electrodes 7 can be made to operate as the light sensing regions successively. With this constitution, one infrared detector can be made to operate effectively as a plurality of picture elements.

Abstract: PURPOSE:To reduce errors attributed to the constitution, and improve accuracy, by detecting the deviation between reference bodies and intersections of a base lattice, and calibrating the reference point of an electron beam. CONSTITUTION:On a table on which material to be worked is mounted, reference bodies 24a... are set at specified positions in each field so as to correspond with each field 21a-21f.
