Abstract: ABSTRACT         An electrophotographic copying process and apparatus fast in operation and capable of making reproduced images having substantially the same image density is provided.  In accordance with the present invention, pre-exposure is carried out only when a photosensitive member is to be used for image formation after elapsing a predetermined time period during which the photosensitive member has been kept unused.  The present invention is fast in operation and minimal in power consumption because the pre-exposure is skipped when un-necessary.  However, since pre-exposure is effected when necessary, the image density may be maintained at constant.

Abstract: ABSTRACT        A method and an apparatus for detecting a fault and a fault direction in electric lines.  The voltage and current is measured simultaneously at at least one location in the electric lines to form a voltage and current step signals (Su, Si) based on the measuring.  A Cartesian coordinate system is established defining four quadrants and an origin.  The coordinate system has one coordinate corresponding to the voltage step signal Su and another coordinate corresponding to the current step signal Si, wherein each pair of the simultaneously measured signals Su, Si forms a point in the coordinate system and the points define a line of motion progressing from one quadrant to a next adjacent quadrant.          Predetermined triggering boundaries are established in each of the quadrants as well as  predetermined boundary zones to a predetermined depth from each triggering boundary towards the origin.  The progress of the line of motion is monitored relative to the triggering boundaries and the boundary zones.          At least a triggering boundary in the next adjacent quadrant is displaced upon a detection and a monitoring step that the line of motion has entered the boundary zone of the one quadrant.  A fault is detected upon a detection in the moni-toring step that the line of motion has transgressed a triggering boundary and a fault direction is detected based on the quadrants in which a fault detection is made.  A triggering signal is generated upon a detection in the monitoring step that the line of motion has transgressed a triggering boundary.

Abstract: ABSTRACT OF THE DISCLOSURE     A laterally shiftable needle bar of a tufting machine, carrying a plurality of laterally spaced needles, is reciprocated in a vertical path for simultaneously inserting loops of yarn, carried by the needles, through a base fabric, the fabric being fed in a linear longitudinal path beneath the needles.  Each needle has an individual looper below the base fabric, in registery and  cooperating with the needle for engaging and temporarily holding the loop of yarn, inserted by the needle through the base fabric, as the needle is retracted During a firs portion of a cycle of the needle bar, prior to the insertion of the needles through the base fabric, a needle bar shifting assembly shifts the needle bar laterally, in one direction or the other.  Then, after the needles have penetrated the base fabric, the needle bar shifting assembly shifts the needle bar laterally in an opposite direction, so as to cause the needles to move, the penetrated position of the base fabric laterally out of its normal linear path and align the needles with their loopers beneath the base fabric for engagement of the loops by the loopers, as the needles are withdrawn vertically from the base fabric.  The resiliency of the base fabric returns the shifted portion of the base fabric to its original linear path across the machine and the yarn inserting cycle is then repeated.  By appropriate maniuplating of the lateral shifting of the needle bar one or, indeed, a plurality of longitudinal rows of tufts are produced by each needle and its individual looper.

Abstract: CONTINUOUSLY VARIABLE FIBER OPTIC DELAY LINE          Abstract of the Disclosure A continuously variable optical delay line having a first substrate  (66,  70)  and a second substrate  (95). the first substrate is composed of a quartz block (70) with  a  large  radius  of  curvature  along  its  length, supporting a silicon substrate  (66) having a plurality of  longitudinal, parallel  v-grooves  (68).   A single length  (121)  of single mode  optical fiber  is wrapped around the first substrate (66, 70)  in helical fashion with each loop being secured  in one  of the v-grooves (68).  The portions of the fiber (121) in the v-grooves (68) are lapped and polished to create a flat coupling surface extending  laterally  and  longitudinally  across the first substrate (66, 70).  The second substrate (91) is  composed of a quartz block with a single v-groove holding a segment of single mode fiber (95).  The radius of curvature of this v-groove is substantially smaller than  that  of  the  first  substate,  such that the flat coupling surface of the second substrate (91) is shorter than that of the first substrate  (66).   The first and second  substrates  are  placed  together  such  that  the fiber in the second substrate is coupled to the fiber in the  first  substrate.   By  moving  (142)  the  second substrate  longitudinally  with respect  to  the  first substrate,   a   continuously  variable  delay   can  be obtained.   The continuously variable delay line can be combined with a separate discretely variable delay line to  created a  longer continuous variable  delay.   The continuous variable delay line can be formed with only one v-groove (68) in the first substrate (66).
