Title: Rotary magnetic head drum
Inventor: AZUMA RIYUUSUKE
IPC: G11B5/52
Filed: 1989-12-25
Abstract: PURPOSE:To provide the rotary magnetic head drum made of plastic by insert molding free from cracking by forming a molding member so as to have the coefft. of thermal expansion of about 1/4 to 3 times the coefft. of thermal expansion of an insert member. CONSTITUTION:The core material 11 is molded to a drum shape and particularly to the drum shape in such a manner that the part to serve as an important reference plane is formed. The drum 1 is formed of the core material 11 as skeleton and the thin plastic 12 which covers the surface thereof. Since the plastic 12 covering the core material 11 is thin, the shrinkage after the molding is suppressed to an extremely low level. In addition, the coefft. of thermal expansion of the molding member is about 1/4 to 3 times the coefft. of thermal expansion of the core material 11 and, therefore, the difference in the thermal expansion with the core material 11 and the difference in the shrinkage there from are confined within the tensile stress of the plastic 12. The cracking is, therefore, obviated even if the layer of the plastic is formed thin.

Title: Optical fiber coupler for heterodyne detection
Inventor: KAJIOKA HIROSHI
IPC: H04B10/29
Filed: 1987-12-29
Abstract: PURPOSE:To perform high-performance heterodyne detection by deviating the characteristic polarization axes of a single polarization optical fiber and a double refractive index optical fiber by 45 deg. from each other, determining the length of the double refractive index optical fiber under specific conditions, and connecting at least one of remaining projection terminals of a directional coupler to a photodetector. CONSTITUTION:The single polarization optical fiber 5 and double refractive index optical fiber 6 which constitute a circular polarization fiber part 4 are connected having their characteristic optical axes deviated by 45 deg. from each other, and the length of the double refractive index optical fiber 6 is so determined that l=2mL+ or -L/4 (where (m) is an integer and L is beat length). Local oscillation laser light passes through the single polarization optical fiber 5 of the circular polarization optical fiber 4 to become a linear polarized wave. This is split into two orthogonal polarization modes and propagated in the double refractive index optical fiber 6 and supplied to the directional coupler 3 in a circular polarized state. Consequently, a communication wave which is projected from an optical cable 9 and incident on the incidence terminal 7a of an optical fiber coupler 1 interferes with a local oscillation wave from a local oscillation laser 8 in the directional coupler to perform the heterodyne detection excellently.
