摘要： A weft picking system of a loom comprises a weft winding-guide arm which wounds a weft yarn around a stationary drum in order to measure a weft length to be required for one pick of the weft yarn. The weft winding-guide arm is driven by a pulse motor whose revolution speed is slowly decreased from a predetermined level toward a stoppage of revolution of the pulse motor so as to measure a predetermined part of a required weft length, while is slowly increased into the predetermined level since the initiation of the pulse motor revolution so as to measure a remainder part of the required weft length, thereby effectively preventing the weft yarn from being cut.

摘要： A pressure sensing device constructed of a high molecular conductor kept in contact at all times with at least one pair of electrodes in a circuit and wherein the resistance of the conductor is sensitive to external forces oppositely applied by an actuator and a spring. Changing of the relative value of the forces changes the conductor resistance thus changing the circuit resistance.

摘要： A scanning circuit device for providing analog switching action for a one dimensional image sensor, comprising a voltage source (1) for providing a sawtooth wave, a first (Da.sub.1 -Da.sub.3) and a second (Db.sub.1 -Db.sub.3) group of diodes, and a first (Ra.sub.1 -Ra.sub.3) and a second (Rb.sub.1 -Rb.sub.3) group of resistors. The two groups of diodes become sequentially conductive in response to the sawtooth wave, with the result that a set of circuit elements (S.sub.1 -S.sub.3) connected in parallel with the second group of diodes are sequentially scanned electrically. The diodes used as analog switches are easier to fabricate than transistors.
