Title: Process for prebaking substrates coated with positive photoresist based on naphthoquinonediazide and phenolformaldehyde resin
Inventor: SIGUSCH REINER DIPL ING
IPC: G03F7/16
Filed: 1983-02-21
Abstract: In a process for prebaking substrates coated with positive photoresist based on naphthoquinonediazide and phenolformaldehyde resin, the substrates are brought in less than three seconds to the prebaking temperature, which is in the range from 110 to 140 DEG C, and the prebaking time is set in the range from 5 to 60 seconds depending on prebaking temperature. The process makes possible a good resist adhesion, low solvent residues, high photosensitivity, good etch resistance and the elimination of stresses in the photoresist layer. The process is used in photolithography procedures for manufacturing integrated circuits. <IMAGE>

Patent DE-3344329-A1 (DE)
Inventor: KEILHAU KARL FRIEDRICH
IPC: A63B49/08
Filed: 1983-12-08
Abstract: A racket for ball games and more specifically, a tennis racket, has a frame forming a racket head, a shank and a grip secured to the shank with a force fit so that the grip may be turned in relation to the racket head into different settings. The force fit connecting elements are simple to manufacture, yet permit an exact stepless setting and a satisfactory transmission of the forces produced while still avoiding a slip clutch effect. The grip and the racket shank are joined with each other by a surface area of substantial size which assures the required frictional engagement for the force fit in the angular direction while providing a form locking connection in the axial direction. The shank is part of an integral, one-piece handle bar which also has a cylindrical section and a conical section integrally interconnecting the shank to the cylindrical section.

Title: Adjusting device for drill-bit carriers
Inventor: KNUT MICHAEL
IPC: B23B29/034
Filed: 1984-04-21
Abstract: The invention relates to an adjusting device for drill-bit carriers in reboring tools for metalworking, for adjusting the drill-bit cutting edge to a specific working diameter. The aim of the invention is to develop an adjusting device, in which the components for securing the set screw axially in position allow an essentially play-free axial support of the set screw in both setting directions for the purpose of improving the adjustment operation. The object on which the invention is based is to improve the axial support of the set screw on an inner retaining ring. This object is achieved, according to the invention, in that the inner circumferential groove receiving the inner retaining ring in the guide bore of the basic body has a conical groove flank and a straight groove flank and, in relation to the spread-open inner retaining ring, a smaller annular cross-sectional diameter, with the result that the inserted inner retaining ring is laid with expanding tension against the straight groove flank of the inner circumferential groove in a manner free of play. <IMAGE>

Title: Method and device for monitoring ground movements and locating their depth
Inventor: EISENBLAETTER JUERGEN DR
IPC: G01S11/14
Filed: 1984-05-25
Abstract: In order to identify and locate the depth of ground movements, especially of settlements, subsidences or shifts in the case of tunnel, road or dam constructions, a U-shaped acoustic waveguide is fitted in the location of the movement. The sound waves produced by friction of the moving material on the limbs of the waveguide are detected by means of two sound-emission recording devices. The distance of the movement from the surface of the earth is determined electronically from the time difference between the acoustic signals and the known total length of the waveguide.

Title: Process for producing packing material bodies
Inventor: VOSS GERD DIPL ING
IPC: B29C48/50
Filed: 1984-06-09
Abstract: In a process for producing pourable spherical segment-shaped packing material bodies of plastic with a surface which is externally convex and internally concave, the plastic is introduced from a filling hopper through an opening into a bush surrounding the extruder screw. The plastic is plasticated and, because of the velocity difference prevailing over the melt cross-section, emerges from a die orifice with a curved surface. The plastic strand is cut off directly at the die orifice and still before a significant expansion has taken place. The plastic material is fed into a space between the extruder screw and a bush (28) provided with longitudinal grooves (35) in the material feed zone (13). This provides a possibility for some of the plastics granules to escape into the longitudinal grooves (35), resulting in an increased and more constant transport of material through the extruder.

Title: Apparatus for drilling a hole with an electron beam
Inventor: HOWARD CURTISS GILMORE
IPC: H01J37/31
Filed: 1984-07-31
Abstract: During the drilling of holes of very small diameter in workpieces 24 by means of an electron-beam drilling machine, the material 40 discharged from the workpiece has a great tendency to travel back along the beam path and settle as a deposit 50 in the interior of the electron gun 22. Provision is made for the deposit to settle for the most part in a recess 54 at the margin 60 of a rotatable, inner diaphragm 44 which is arranged near the beam path inside the electron gun. The deflection angle  alpha  of the electron beam is accurately set so that the material discharged from the workpiece settles in the recess, from which the material is removed by means of a wiper. A nose 64 is arranged in the recess at the margin of the diaphragm and helps to remove small quantities of deposits 50 which are still adhering to the stationary parts of the electron gun near the diaphragm. In this embodiment, an elastically flexible wiper, such as, for example, a wire brush 66, is used in order to remove adhering deposits from the margin of the diaphragm. <IMAGE>
