Title: Method and equipment for reflow soldering
Inventor: NAGAI KOICHI
IPC: H05K3/34
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to apply appropriate quantity of heat to each substrate even if the temperature in a furnace changes, by setting the reflow time appropriate for each stage for each substrate when a reflow-soldered substrate reaches a reflow section, and then reflow-soldering the substrate for the set reflow time.

For continuous production, succeeding substrates 1 are put on the conveyor line one after another and the placing interval between the substrates 1 is recognized by the detection of the substrates 1 by the substrate detecting sensor 2. A control unit 3 classifies the substrate placing intervals into several stages according to a predetermined criterion. When the reflow-soldered substrates 1 reach a reflow section 5, the control unit 3 changes the setting of reflow time to the one appropriate to each stage for each substrate 1 and then each substrate 1 is reflow-soldered for the set reflow time.

Title: Optical element and optical wavelength shift method
Inventor: CASSIDY STEPHEN A
IPC: G02F1/35
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To make possible shifting a wavelength of an optical signal with simple constitution by irradiating first, second coherent waves with wavelengths different from each other on a variable refractive index part, generating an interference pattern and generating a refractive index grating moving along a one-dimensional optical waveguide with the time with this interference pattern. SOLUTION: The variable refractive index part 1 is formed on a part of the one-dimensional optical waveguide 2 by a medium whose refractive index is changed by light intensity, and the grating is formed on the variable refractive index part 1. That is, two external interferable beams 3, 4 interfere with each other to form the interference pattern, and by modulating the refractive index of the variable refractive index part 1 with this interference pattern, the grating is formed there. When the interferable beams with the wavelengths different from each other are used as the interferable beams 3, 4, the interference pattern is moved with the time along the one-dimensional waveguide 2, and a Doppler shift occurs in the wavelength of the reflected signal, and the wavelength shift is realized. Thus, the optical wavelength is shifted with simple constitution.
