Abstract: PURPOSE:To obtain an unwinding control device free from sagging and tensile distortion by performing its speed control in such a way as to obtain the unwinding speed conformed to the specific equation from an unwinding diameter, a take-up diameter, a final take-up diameter and the take-up speed. CONSTITUTION:In a speed command circuit 9, the final coil diameter Da of a take-up machine 5 is set at a setter 10, squared at a square-law circuit 11, this arithmetic result Da<2> is subtracted from the set value K of a setter 12 at a subtracter 13, and from this arithmetic result, a square root is obtained at a square root circuit. The divisor of the coil diameter Da is obtained at a divider 15, and the divided result is multiplied by the take-up speed N2 of the take-up machine 5 at a multiplier 16 so as to obtain a speed command N1. The take-up speed N2 is detected at a tacho-generator 17 directly connected to a motor 6, and the set value K of the speed command circuit 9 is set from the take-up diameter D2 of the take-up machine 5 and the unwinding diameter D1 of an unwinding machine 1 according to K = D1<2> + D2<2>. The line speed with the constantly conformed take-up quantity can be thus obtained by the speed command N1 to this unwinding machine 1.

Title: Fluororubber coating composition
Inventor: FUKUSHI TATSUO
IPC: B05D7/00
Filed: 1992-11-27
Abstract: PURPOSE: To obtain a compsn. for coating fluororubber which does not require the treatment of a metallic surface with a primer before coating, does not cause gelling, has stability and is rapidly vulcanized after coating.  
     CONSTITUTION: The compsn. for coating fluororubber contains 2-50 pts.wt. Schiff base of an amine-contg. silane compd. based on 100 pts.wt. fluororubber and such an amt. of an org. solvent that the amt. of solids ranges from 10 to 60 wt.% of the entire compsn. as essential elements. Since the amine-contg. silane coupling agent as a vulcanizer for fluororubber is inactivated in the form of the Schiff base and used in the compsn., the compsn. does not cause gelling during transportation and storage and has stability over a long time. Since the Schiff base is decomposed by heating after coating to liberate the active amine-contg. silane compd., the compsn. can rapidly be vulcanized. Since the amine-contg. silane coupling agent acts to stick the fluororubber to a metallic surface, the treatment of the metallic surface with a primer before coating is not required.

Title: Optical filter and liquid crystal display element using optical filter
Inventor: HADO HITOSHI
IPC: G02B5/30
Filed: 1987-12-17
Abstract: PURPOSE:To apply optical correction characteristics having a liquid crystal cell to an optical filter and to attain cost down by laminating plural thin films having uniaxial optical axes to be almost rectangular to the thickness direction of the thin films so that the optical axes of adjacent thin films form the deviation of a fine angle and the whole optical axes are twisted in a prescribed direction. CONSTITUTION:Since the optical axes of adjacent thin films 26 have the deviation of a fine angle in an optical filter, the angle of rotation which has a fine angle to an incident light can be obtained. Since the whole of the plural laminated thin films 26 has a prescribed twist angle phi, the incident light is optical rotated by the twist angle phi. Namely, similar action to a liquid crystal display element consisting of two super twist type liquid crystal display elements can be obtained. Consequently, high contrast having no color can be obtained, and since only one liquid crystal cell is used, cost down can be attained.

Title: Diode phase shifter
Inventor: HIRAHATA NAOMI
IPC: H01P1/185
Filed: 1988-12-19
Abstract: PURPOSE:To apply impedance conversion between a main line and a pad gradually and to reduce the deterioration in the VSWR by forming a conversion section between a main line and a square pad with a DC cut capacitor mounted thereto. CONSTITUTION:A drive bias voltage is supplied externally from a bias pad 10 and fed to a diode 3 via the main line and a load line. In this case, the drive bias voltage is turned on/off to vary the susceptance value of a device line 8 when viewing from the main line 7 and also the transmission phase. The difference between transmission phases is a phase shift quantity. Moreover, since a DO cut capacitor 4 exists to the input and output side, the drive bias voltage does not give effect on other circuit connecting to the phase shifter. Since the connection part between the main line 5 and the pad is formed tapered, gradual impedance conversion is attained and reflection is suppressed.
