Title: Method for controlling yarn processing position of weft knitting machine and device therefor
Inventor: MORITA TOSHIAKI
IPC: D04B7/26
Filed: 1992-06-17
Abstract: PURPOSE:To previously process a yarn and precisely change over the processed yarn at a desired knitting position. CONSTITUTION:A yarn 12 fed to a weft knitting machine 10 is processed by a yarn processing device 18 to change over properties of yarn. In the yarn processing device 18, it is required to previously operate at an operation position C in order to change over the yarn 12 at a change over position B on a knitted fabric 11. A controller 21 calculates the operation position C from a set value of set circuit 22 and pattern data of memory 23 and when it is detected that yarn feed position to knitting needle attains the operation position C by an encoder 16, the yarn processing device 18 is operated. Length of the yarn from the yarn processing position A to the operating position is nearly equal to sum S of loop length for knitting a part from the operation position C to a changeover position D.

IPC: G02F1/13
Filed: 1977-12-28
Abstract: PURPOSE: To apply an effective voltage, optimum to a temperature, to a liquid- crystal display panel by providing a temperature detecting method and by allowing effective voltages in a selection state and unselection state to vary with temperature.  
     CONSTITUTION: Temperature detecting method 1 consists of thermistor 8, capacitor 9, P-MOSFET 10, inverters 10 and 12, AND gates 13 and 16, NAND gate 15, and octal counter 14 and performs the digital conversion of temperature corresponding to time constants of thermistor 9 and capacitor 9. On the other hand, counter 2 counts eight clock pulses CP 2 , and digital comparator 3 compares the counting contents of counter 2 with the number of clock pulses obtained by digital-converting the temperature by temperature detecting method 1, so that when they agree each other, a signal will be outputted. By this signal, duty-signal generating circuit 4 varies the duty of an output signal to control digit and segment driver circuits 5 and 6, thereby controlling an effective voltage applied to liquid-crystal display panel 7. In this way, the control is so done that neither crosstalk nor application of an unneeded overvoltage will occur.
