Abstract: PURPOSE:To obtain an optical fiber coupler which can be used in a wide wavelength area by making a refractive index of a core of at least one piece of optical fiber different from a refractive index of a core of the other optical fiber. CONSTITUTION:As for an optical fiber coupler 11, a melting point part 14 is formed by fusing and drawing a part of two pieces of optical fibers 12, 13 whose fiber diameter and mode field diameter are equal, and also, whose refractive indexes of cores are different from each other. One optical fiber 12 of the optical fibers 12, 13 consists of a core 15 whose material is SiO2 obtained by doping GeO2 and a clad 16 whose material is SiO2. The other optical fiber 13 consists of a core 17 whose material is SiO2 and a clad 18 whose material SiO2 obtained by doping F to SiO2. A refractive index of the core 15 whose material is SiO2 obtained by doping GeO2 is higher than that of the SiO2 core 17, and as for both the fibers 12, 13, since the refractive indexes of the cores 15, 17 are different, even if the fiber diameter and the mode field diameter are the same, propagation constants of each of them are different, and the coupler 11 having a satisfactory symmetric property of a shape and an excellent characteristic is obtained.

Filed: 1991-09-05
Abstract: PURPOSE:To suppress the adhesion and accumulation of metallic dust generated due to discharge on the optical window surface by providing a static gas chamber which can hold a space to generate no gas flow even if any gas circulates around the optical window. CONSTITUTION:A static gas chamber 7 is provided near an optical window 3 at the end section of a laser tube 1, and a space is preserved to generate no gas flowing even due to the gas circulation.

Filed: 1983-11-30
Abstract: PURPOSE:To vary both rise and fall delay times of an input pulse with a small- scale circuit by supplying an integrated output pulse to a comparator which can give the hysteresis variation to the fall and rise threshold levels. CONSTITUTION:An inverted input pulse is supplied to an integration circuit, and an integrated output pulse is supplied to a comparator 6 which can give the hysteresis variation to the fall and rise threshold levels.

Title: Multi-cavity mold device
Inventor: OBARA MITSUHIRO
IPC: B29C45/26
Filed: 1994-09-22
Abstract: PURPOSE: To offer a balance in filling cavities without recourse to a temperature control and reduce the thickness of a manifold. CONSTITUTION: A resin flow to cavities is branched into eight in total through a primary runner 29, a secondary runner 30, and tertiary runners 31a, 31b disposed to be flush with each other. The tertiary runner 31a is a reverse tertiary runner turned back to the primary runner 29. The tertiary runner 31b is a forward tertiary runner directed oppositely to the runner 29. The diameter of the forward tertiary runner 31b is determined to be larger than that of the reverse tertiary runner 31a. Intrinsically, a resin flow to the forward tertiary runner 31b is not smooth in comparison with a resin flow to the reverse tertiary runner 31a. However, this tendency can be compensated with the setting of the diameters. Since the primary runner 29, the secondary runner 30, and the tertiary runners 31a, 31b are disposed to be flush with each other, a manifold 21 can be reduced in thickness.
