Title: Manufacture of resin molded coil
Inventor: ITOU YOSHIHIRO
IPC: H01F41/12
Filed: 1983-01-14
Abstract: PURPOSE:To obtain a resin sealed coil having no defect in its cooling air passage by such an arrangement wherein an end insulator is provided outside the upper and lower ends of conductive wound layers, and a heat-resistive board which is hard to be impregnated with resin is arranged at the internal surface of a wound layer facing to a cooling air passage and an insulator treated by a hardening accelerator is also provided outside the layer. CONSTITUTION:A secondary coil 2 is provided on a wind frame 11, a lead wire 2b is drawn out and a glass tape 3 impregnated with a hardening accelerator is wrapped around it. A cooling air passage is formed by a space insulator 4, a conductor 6a is wound around through a heat-resistive board 12, and a primary coil 6 is wound by overlapping plural wound layers, one over another, through an insulator 7 between layers and a lead wire 6b is drawn out. Next, a glass tape 9 treated by a hardening accelerator is wound around it. Asbestos 8 is provided outside the upper and lower ends of wound layers of the coils 2, 6. Since heat-resistive boards 11, 12 are made by pasting mica boards 16 together, they are hard to be impregnated with resin. When the lower end of the coil is immersed in solution of hardening accelerator and it is caused to impregnate it under vacuum, the resin is gelled and it prevents resin not hardened yet from leaking and by heating the coil, a resin sealed coil excellent in cooling capacity can be obtained.

Title: Temperature compensating device of optical transmission system
Inventor: NAITOU HATSUHIKO
IPC: H04B10/293
Filed: 1983-01-13
Abstract: PURPOSE:To compensate simply the temperature dependancy of an optical transmission system by inserting a thermister having a temperature dependency reverse to that of the optical transmission system in series with an LED. CONSTITUTION:When a prescribed current flows to a light emitting element LED2, the light proportional to this current is fed to a photodetector PD2 via an optical fiber OF2 and converted into an electric signal. In the optical transmission system, the temperature dependency of an electric signal output to an electric signal input is shown in a figure. In connecting two thermisters R1T, R2T of the optical transmission system in parallel, the combined resistance value RT is expressed as RT=R1.R2.T/(R1+R2), where R1, R2 are resistance values of thermisters R1T, R2T respectively and T is a temperature in  deg.C. Thus, in setting the temperature dependancy of the combined resistance RT inverse to the characteristic shown in the figure, a current flowing to the LED2 changes with the change in the resistance value RT in response to the temperature change and the temperature dependency is compensated.

Abstract: PURPOSE:To obtain a highly stereoregular poly-alpha-olefin in high yields per unit weight of an active titanium catalyst, by polymerizing an alpha-olefin in the presence of a catalyst comprising an active titanium component, an organoaluminum compound and a specified aromatic carboxylic acid ester. CONSTITUTION:An alpha-olefin is polymerized in the presence of a catalyst comprising an active titanium component obtained by impregnating a magnesium halide with a titanium halide, an organoaluminum compound and an aromatic carboxylic acid ester of a moisture content <=500wt.ppm.

As the aromatic carboxylic acid ester, an alkyl ester of an aromatic monocarboxylic acid is desirably used. When the moisture content of the ester is higher than 5,000wt.ppm, the activity at the same addition ratio is poor. When the compounds are added so that the same activity may be obtained, the stereoregularity of the obtained poly-alpha-olefin is lowered.
