Title: Manufacturing method of metallic short fiber
Inventor: NAKAGAWA TAKEO
IPC: B23P17/06
Filed: 1979-05-29
Abstract: PURPOSE: To successively cut producing superfine fibers with a uniform dimensional shape or physical properties, by turning a column-shaped metallic block with a tool having a prescribed rake angle and depth of cut.  
     CONSTITUTION: A metallic block 1 of column shape is turned by a lathe with a tool 3 having a prescribed rake angle θ and depth of cut, and needle-shaped short fibers 6 of noncircular cross section are successively cut and produced with a natural crack of the material. When the rake angle is negatively applied larger to a cutting edge part of the tool 3, fine and hard fibers 6 are obtained. While a smaller amount of its feed allows the fibers to tend to have their smaller cross sections. If appropriately selected the amount of rake angle, cutting speed and feed motion, the superfine short fiber 6 with a relatively uniform dimensional shape and physical properties can be easily obtained in a quantity production.

Abstract: PURPOSE: To provide a method for eliminating noise from a base band television(TV) picture signal such as luminance or chrominance passed through a noise leading route. CONSTITUTION: An input 12 receives a luminance component Y1 and reaches a node 16 through an one-frame delay circuit 14 and a luminance component Y2 reaches a node 20 expressing a luminance component Y3 delayed by two frames through an one-frame delay circuit 18. The luminance component Y1 passes through a minus 1/4 amplitude gain amplifier 22, the luminance component Y2 passes through a plus 1/2 amplitude amplifier 24 and the luminance component Y3 passes through a minus 1/4 amplitude amplifier 26. Functions -1/4V1 , +1/2V2 , -1/4V3 are outputted from a node 30 and coupled with each other by a coupling circuit 28. An output on a line 34 is the average of low level picture information (noise or movement) in respective frames which are mutually unrelational and reduced from the luminance signal Y2 by a subtracter circuit 36.  Noise removal to be attained by a system 10 is equal to V[(-1/4V1 )<2> +(1/2V2 )<2> +(1/4V3 )<2> ]. The square route is equal to 2dB noise improvement.
