摘要： A lifting-lowering assembly for a stylus arm employs two flat portions having a pivot axis in the vicinity of the intersection of the two portions, a stylus arm rest on the first portion, and, an upwardly extending member on the second portion. The upwardly extending member cooperates with an electromagnetic device to rotate the assembly about the pivot axis. Air trapped under the first and second flat portions tends to permit gentle lifting and lowering operations by damping the rotational motion of the assembly.

摘要： A method for lapping two flats of substantially the same dimensions in an element having a cone-shaped tip. The method includes the steps of contacting a first region of the cone wherein a flat is to be lapped while the cone is in contact with the lapping surface; rotating the element to a second region wherein a second flat is to be lapped while the tip is in contact with the lapping surface without the cone tip contacting or disturbing the lapping surface; contacting the second region of the cone with the abrasive lapping surface for a predetermined time; and repeating the previous steps until the two flats have been lapped. The time each region contacts the lapping surface is substantially equal and the time during which the element is rotated is small compared to the time each region contacts the lapping surface.

摘要： Apparatus for orienting a cutting stylus having a mounting face and a cutting face includes a base member having a flat, nonadhesive surface and a stylus holding fixture. The stylus holding fixture includes a mounting block having a surface vertical to the flat, nonadhesive surface of the base member. The cutting stylus is attached with epoxy to the vertical surface of the mounting block which forms the proper angle to orient the cutting face of the stylus for subsequent lapping on a lapping machine. A capping plate having a recess for the cutting stylus is attached to the mounting face of the mounting block. With the stylus mounted in the mounting block the stylus holding fixture may now be placed on a lapping machine for the stylus lapping process.

摘要： A stylus assembly for damping impulsive radial motion of the stylus during playback of a grooved video disc record. Included in the stylus assembly is a moment arm perpendicularly attached at the free end of the stylus arm and parallel to the disc record when the stylus is engaged for playback. A mass is mounted to the moment arm to contribute increased inertia to lateral motion of the stylus only in a direction radially across the record. The mass is designed to permit tracking a record groove in the presence of groove eccentricity but to resist motion due to impulsive forces imparted by record defects or particulate matter thereon.

摘要： A composite stylus assembly, provided for a grooved disc record playback system, includes a playback stylus supported on a free end of an arm. The other end of the arm is supported by a flexible mount in a cartridge. The stylus rides in the groove of the record for information recovery. The arm is located within a hollow tube which is supported at one end thereof by the flexible mount. The free end of the tube includes a mechanism which aids in the steady inward movement of the tube relative to the disc center when relative motion between the disc and the playback stylus is established. When the playback stylus retraces the same groove convolution, the inward motion of the hollow tube exerts enough force on the stylus arm to enable the playback stylus to ride over the walls of the groove.

摘要： A method of polishing a roof-shaped, or bevelled, tip having a predetermined angle on the end of an optical fiber is disclosed. The method comprises placing an optical fiber in contact with an abrasive tape at an angle corresponding to the desired predetermined angle. The fiber is moved towards the tape beyond the point of contact so as to cause a bend in the fiber. Upon moving the abrasive tape, the compliance of the fiber, by virtue of the bend, provides a pressure of the fiber against the tape to enable polishing to occur. As polishing continues the pressure decreases until enough material is removed so as to eliminate the bend and impart the predetermined angle to the fiber tip. The fiber may be rotated to polish the other side in a similar manner, if so desired.
摘要翻译： 公开了一种在光纤端部抛光具有预定角度的屋顶形或倾斜尖端的方法。 该方法包括以对应于期望的预定角度的角度放置与研磨带接触的光纤。 纤维向胶带移动超过接触点，从而导致纤维的弯曲。 在移动砂带时，由于弯曲，纤维的顺应性提供了纤维抵抗胶带的压力，以使抛光发生。 随着抛光继续，压力降低，直到足够的材料被去除，以便消除弯曲并赋予纤维尖端预定的角度。 如果需要，纤维可以以类似的方式旋转以抛光另一侧。
