IPC: B23K11/30
Filed: 1983-11-10
Abstract: PURPOSE:To provide a wide current conducting area without fluid conductive material and to conduct satisfactorily electricity to a rotary electrode roll by interposing the circumferential projecting part of a stationary current conducting shaft in the annular surface of said roll and pressing the plane on the annular surface of the roll by means of the plural pressing brushes disposed in the projecting part. CONSTITUTION:Sintered brushes 9 consisting of graphite-silver are inserted via pressing springs 8 to plural peripheral holes 6 in the circumferential projecting part 5 of a stationary current conducting shaft 2. Half-split electrode rolls 3 having ball bearings 4 are inserted onto the shaft 2 and are fitted and fastened by means of bolts. The outer surface 9c having the largest possible area at the tips of the brushes are pressed to the plane 12c on the annular surface of the roll 3.

Title: Photograph film player
Inventor: SHIMADA MASAKI
IPC: G03B21/00
Filed: 1988-08-25
Abstract: PURPOSE:To prevent unsightly videos produced in the course of frame forwarding by detecting that a roll of film is in a reproducible state and outputting video signal only when the film is in the reproducible state. CONSTITUTION:Pictures of a roll of film are read by an image pickup element 4 and outputted after the pictures are converted into video signals by means of an encoder 5. Upon receiving a frame forwarding instruction from an instruction input section 7, a film driving means 6 forwards the frames of the film 2 and a frame forwarding sensor 8 detects the frame forwarding and supplies detect signals to the encoder 5. Upon receiving the detect signals, the encoder 5 stops the output of the video signals. When the film forwarding is completed and a prescribed frame of the film 2 is set to the optical axis, the detect signals from the sensor 8 are stopped and the encoder 5 starts to output the video signals. Since the output of the video signals is inhibited while the frame forwarding operation of the film is carried on, unsightly video signals do not appear.

IPC: D01D5/16
Filed: 1985-09-27
Abstract: A method of producing a flat polymeric yarn is disclosed which includes the steps of melt spinning a polymer to form a plurality of running filaments, combining the filaments to form a running bundle of filaments, and then guiding the running bundle into contact with a ribbon of fluid so as to apply a controlled quantity of the fluid to the bundle. The fluid coated bundle is guided over a plurality of serially arranged curved braking surfaces, and it is then withdrawn by means of a draw roll so as to draw the running bundle to an extent which exceeds its plastic limit. The application of the fluid to the bundle in accordance with the present invention results in a hydrodynamic friction, rather than a sliding contact friction, between the bundle and braking surfaces, and produces yarn of very uniform quality while also avoiding wear of the braking surfaces.
