Patent KR-840001750-B1 (KR)
Title: Compound covering material of tubular metal members
Inventor: MARCHAL RENE
IPC: F16L58/16
Filed: 1981-06-18
Granted: 1984-10-19
Abstract: Composite outer coating for ferrous metal pipes contain (a) a hardened epoxy or heardened polyester resin bonding layer in contact with the metal, (6) a hydraulic binder-impregnated fiber layer, and (c) an outer sealing layter The coating is deposited by applying to the metal an ambient temp. -hardening epoxy- or polyester resin-contg. compsn; immediately winding a hydraulic binder-impregnated fiber layer around the member; spraying with a sealing layer; and hardening. The coating adheres well to the metal pipe. The coating provides more protection than a coating in which the hydraulic binder-impregnated fiber layer is replaced by a sprayed-on glass fiber- reinforced hydraulic binder layer. Macroelement formation is also reduced.

Granted: 1992-06-01
Abstract: A circuit for aupplying charging current to a battery and which includes a rectifying circuit operatively arranged to provide an unfiltered rectified output and a current regulating circuit connected in series. The current regulating circuit includes a controlled current-carrying stage and a control stage operatively arranged to control conduction of the controlled stage in response to an input signal representative of the unfiltered rectified output from the rectifying circuit. The control stage (38, Figures 2, 3, 4A, 4B, 5A, 5B) is provided with an internal negative feedback path (33-35, Figures 2; 48-50, 52, Figures 3; 3a, 33b, 34, 35, 43, Figures 4A, 4B; 58-61, Figures 5A, 5B) and allows the controlled stage (39-42, Figures 2, 3, 4A, 4B; 64, Figures 5A, 5B) to pass current during periods when the unfiltered output from the rectifying circuit (36, Figures 2, 3, 4A, 5A; 36 min  Figures 4B, 5B) is between a first level, defined by voltage across the battery (24) and a higher second level. External negative feedback may be provided from the controlled stage (39-42, Figures 2, 4A, 4B) to the control stage (38, Figures 2, 4A, 4B).

Title: Method and apparatus for attaching fly strips to a slide fastener chain
Inventor: MIYAGAWA GAZUO
IPC: D05B33/00
Filed: 1985-09-11
Granted: 1987-03-26
Abstract: The method involves sewing a leading end of a preceding fly strip piece (P1) in a sewing machine and then sewing a trailing end. A succeeding fly strip (P2) is then driven towards the machine faster than the machine feed rate so that the leading and trailing ends of the succeeding and preceding strips respectively abut. Such abutment occurs when the preceding strip is being sewn. During driving, the succeeding strip is supported so that its leading end does not overlap or bunch at the preceding strip trailing end. The method also involves continuously delivering a slide fastener chain to the machine for sewing onto the strips.

Title: Positioning method
Inventor: TABATA MITSUO
IPC: H01L21/30
Filed: 1987-02-10
Granted: 1990-05-12
Abstract: The aligning method forms a grating pattern on one object, and a checkerboard-like grating pattern is formed, also as an alignment mark, on the other object. A light beam emitted from an alignment light source is radiated onto the checker-board-like grating pattern of the second object. The light beam diffracted by the checkerboard- like grating pattern is guided onto the grating pattern of the first object. The light beam diffracted by the grating pattern of the first object is detected by a detector. Since the light beam emitted from the light source is diffracted by the checkerboard-like grating pattern, a relative position of the objects can be detected, irrespective of the distance therebetween. The objects are accurately algined, based on the detection result.

Abstract: This system uses one stepping motor to perform  the  sending, receiving, copying and rewinding modes in facsimile system. By the use of this system the  weight  and  costs  can  be  reduced.  The components of this system comprises a solar gear  (2b),  an  idler arm (28),  idler  gears  A,B  which  selectively  connect  to  the read-out gear and the recording gear, a  driven  gear  (33)  being able to spin like the driving axle by an idler  arm  (35),  and  a C- idler gear, placed in the forward part of  the  idler  arm  (35) enabling it to spin freely, always connects to the gear (33),  and also selectively  connects  to  the  readout  gear  (24)  and  the recording gear (25).
