IPC: H01S5/06
Filed: 1994-08-03
Abstract: PURPOSE:To enable reading out of control signals from input signal light without affecting a main signal system of a wavelength converter which converts the signal light of a certain wavelength to signal light of another wavelength.

Title: Treatment of selenium-containing waste water
Inventor: NEGISHI HAJIME
IPC: C01B19/00
Filed: 1991-07-23
Abstract: PURPOSE:To reduce the concentration of selenium by separately adding a metal salt reacting with selenium to produce a slightly soluble salt and a soluble Fe salt not containing SO<2->4 to a selenium-containing waste water in two steps and further maintaining the pH of the reaction solution within a specific range. CONSTITUTION:Raw water containing SeO<2->3 and SeO<2->4 is mixed with a metal salt such as BaCl2 reacting with Se to produce an insoluble salt, thus forming a slightly soluble salt by the reaction of the metal salt with the SeO<2->3 and the SeO<2->4. The suspension containing the precipitates is mixed with a soluble Fe salt such as FeCl3 not containing SO<2->4 in an amount of three times the sum of the remaining SeO<2->3 and SeO<2->4 and further neutralized into a pH of 4.0-5.5 to fix the salt as the insoluble Fe2(SeO3)3. The suspension containing the mixture of the produced precipitates is mixed with a high molecular coagulant for its sedimentation-concentration. The sedimented precipitates are dehydrated and removed as cakes. The remaining overflow is mixed with Na2SO4 and subsequently with an alkali aqueous solution to adjust its pH. A trace amount of suspensoids remaining in the water are filtered off to obtain the clear treated water reduced in the concentration of selenium.

Title: Manufacture of superconductor
Inventor: SUGAWARA KAZUSHI
IPC: H01L39/00
Filed: 1987-07-22
Abstract: PURPOSE:To enable an n-type superconducting layer to be manufactured, by adding boron elements to a perovskite oxide composed of a IIIA element, a IIA element, copper and oxygen. CONSTITUTION:A cylindrical sample (Y1Ba2Cu3O6+delta) having a diameter of 1cm and a thickness of 5mm is prepared by a powder calcining process for example (Te is about 95K). Boron ions 3 accelerated at 100KeV are implanted in this cylindrical sample at a high dose of 10<18>cm<-2>. When boron ions are implanted in the superconductor 1 in this manner, it can be considered that the boron implanted layer 2 has a depth of about 2-3mum from the surface. Since carriers introduced by the boron doping are electrons, a dose exceeding 1X10<18>cm<-2> corresponds to a carrier concentration per unit volume over 3X10<21>cm<-3>, that is higher than the carrier concentration (p-type) of 3X10<21>cm<-3> of the undoped Y1Ba2Cu3O6+delta. Thus, the conductivity type of the boron implanted region is inverted from P-type to n-type.
