Title: Manufacture of optical demultiplexer
Inventor: ABE TAKAHIRO
IPC: G02B6/34
Filed: 1988-07-19
Abstract: PURPOSE:To demultiplex two arbitrary wavelength between two standard wavelength by deriving in advance a relation of a beat point in two wavelength and a parameter for determining an argument of melting and drawing. CONSTITUTION:A relation of a beat point in two standard wavelength (lambdaA, lambdaB, provided that lambdaB>lambdaA) and a parameter T for determining an argument of melting and drawing is derived in advance, and it goes to an argument of melting and drawing corresponding to the beat point in which the parameter T goes to (lambdaB-lambdaA)/(lambda2-lambda1). For instance, in a measuring system containing low-pass and high-pass optical filters, when each germanium sensor Ge selects and receives light beams of 1.3mum and 1.55mum by the filter, the parameter T as shown by the expression I is set in each beat point. In such a case, T denotes a parameter for showing how many times a coupling ratio reciprocatively goes and comes between '0'% and 100% between 1.3mum and 1.55mum. In such a way, demultiplexing between two arbitrary wavelength (lambda1, lambda2, provided that lambda2>lambda1) between the wavelength lambdaA, lambdaB can be designed freely.

Filed: 1981-11-05
Abstract: PURPOSE:To have an efficient mirror finish of surfaces to be ground, by removing especially those films formed at projected parts among passive films produced on the surfaces to be gound. CONSTITUTION:Because the amount of elution owing to electrolytic elution depends upon the electrolytic current according to Faraday's Law, an experimental result is obtained as in the diagram beside, about the relation of the surface roughness ground to the amperage density. In this case the work to be ground is stainless steel SUS304, with a surface roughness of 1mum Rmax approximately, and the amperage density is a value corresponding to the impressed voltage 3-23V. The solid line shows the experiment with a grinding  time of 1min and the broken line, longer than one minute. The 4 volts is approx. 0.3A/cm<2> and 20V approx. 2.5A/cm<2> in the practical impression voltage range. Accordingly a pure mirror-finished surface with 0.3mum Rmax or less is obtained efficiently under the condition that the electrolytic liquid density is no more than 2.5A/cm<2>.
