Inventor: KURIYAMA YOSHIO
IPC: B21B45/02
Filed: 1978-03-24
Abstract: PURPOSE: To greatly improve the passableness of the strip, and to improve the stability and quality of the operation, by a specified angle inclining the injection angle of the lower spray nozzle toward the downstream of the flow of the strip, and by injecting the cooling water against the strip.  
     CONSTITUTION: The strip 1 is conveyed on the hot run table roller 2 from the right to the left along the direction of the arrow A, from the mill toward the coiler. A series of lower spray headers 3 for supplying the cooling water are installed among the hot run table rollers 2; the cooling water is injected from the nozzles 4 of these spray headers 3, inclining by an angle θ against the conveying direction of the strip, that is, toward the downstream of the conveying direction, within the range between the arrow B and the arrow C. The injection angle θ is tanged in about 5W30 degrees. If the angle is smaller than 5 degrees, the strip is floated, and if the angle is larger than 30 degrees, the cooling capacity for the strip is lowered, hence these cases are both undesirable.

Title: Automatic frequency controlling system
Inventor: OKINAKA HIDEO
IPC: H04B7/15
Filed: 1982-03-04
Abstract: PURPOSE:To attain an AFC (automatic frequency control) resistant to noise and having narrow band, by using a modulation wave with a PN code series for a reference pilot signal and controlling a local oscillating frequency with a difference between the carrier component of the pilot and a nominal carrier frequency. CONSTITUTION:In a reference pilot forming circuit 6, a carrier is modulated with the PN code series from a PN code generator 3 with a ring-balanced modulator 2 and outputted to an output terminal 5. Only the reference pilot of a reception signal (intermediate frequency) is inputted to a correlation device 9, where the PN code series and the pilot of the two-phase PSK wave are multiplied and correlation is taken for both. A phase locked circuit 11 controls the phase of the code series of a PN code generator 10 so as to maximize the correlation output. Thus, the carrier component of the original reference pilot are inputted to a carrier extracting circuit 12 and outputted to a PLL13 only when the input level is a prescribed threshold or over. The PLL13 outputs the frequency difference between the input signal and the nominal frequency signal as a control signal to control the local oscillating frequency so as to make the frequency difference to zero.

Abstract: PURPOSE:To obtain the title particles containing a uniformly dispersed colorant and excelling in hiding power by dispersing a colorant in a lowly viscous solvent, adding the dispersion to a urethane polymer, and emulsifying the obtained mixture in water containing an emulsifier and a protective colloid. CONSTITUTION:A process for producing colored fine high polymer particles comprising a polyurethane and a polyurea resin, wherein the purpose fine particles are obtained by mixing a dispersion prepared by dispersing a colorant in a lowly viscous solvent with a polyol resin and a polyisocyanate compound and/or a urethane prepolymer and emulsifying the obtained mixture in water or a paraffinic solvent containing an emulsifier and/or a protective colloid. Generally, a colorant is powdery and has a primary particle diameter of 1mum or below but it is in the form of lumps of several tens of mum because of secondary agglomeration. When it is agitated in the lowly viscous solvent, a turbulent flow is easily formed to give a shear sufficient to disintegrate the secondary agglomerated and to effect its uniform dispersion.
