Title: Ion water making apparatus
Inventor: IKENO SHINOBU
IPC: C02F1/46
Filed: 1988-08-26
Abstract: PURPOSE:To prevent the presence of an org. acid radical in formed ion water and to easily supply a calcium source by using calcium carbonate as the calcium source. CONSTITUTION:The carbonated water formed in a container 7 is brought into contact with calcium carbonate stones 10 in a calcium ion-containing water making means 9 to obtain raw water containing a calcium ion at high concn. This raw water is supplied to an electric cell 11 to form alkali ion water 15 containing a calcium ion in a concentrated state in a cathode chamber 16 by electrolytic reaction. The alkali ion water 15 thus formed contains no org. acid radical and the acidic water formed in an anode chamber 17 also contains no org. acid radical. The replenishment and replacement of calcium carbonate stones 10 become easy because only the replacement of said stones in a packing container 90 may be performed and dissolving work is unnecessary. The replenishment of carbon dioxide is also easy since it is performed by the replacement of a carbon dioxide cylinder.

Title: Optical demultiplexer
Inventor: NISHI NORIO
IPC: G02B6/34
Filed: 1983-11-15
Abstract: PURPOSE:To obtain an optical demultiplexer which has wide passing wavelength band width by allowing diffracted light from a diffraction grating to travel backward through a corner cube, and making it incident to the diffraction grating again. CONSTITUTION:An incident light beam from an incidence fiber 13 is converted by a distributed index rod lens 14 into parallel luminous flux, which strikes the diffraction grating 16 installed at a specific angle through a glass block 15. The diffracted light within a wavelength range lambda-lambda2 converges on the reflective surface of a corner cube 17-a and then guided as backward traveling divergent light to the diffraction grating 16 again. The parallel luminous flux diffracted again by the diffraction grating 16 passes through the distributed index type rod lens 14 to converge on the end surface of a projection fiber 18-a. Similarly, diffracted light within a wavelength range lambda3-lambda4 is reflected by a corner cube 17-b to converge on a projection fiber 18-b.

Title: Polishing
Inventor: WATANABE SEIICHI
IPC: B24B1/00
Filed: 1988-08-27
Abstract: PURPOSE:To accomplish a fine polishing operation by a method wherein a hardened region is formed by implantation of ions into a member to be polished and a desired thin film is polished accurately by using the hardened region as a guide to a polishing operation. CONSTITUTION:A silicon dioxide layer as an insulating layer 2 is formed on a silicon wafer as a member 1 to be polished; after that, ions are implanted into the silicon wafer as the member 1; hardened regions 41, 42 are formed. Another silicon wafer as a base stage 3 is pasted on the insulating layer 2. After the base stage 3 has been pasted, the member 1 is polished. Since the regions 41, 42 are formed, a polishing speed is slowed sharply as soon as a polishing operation reaches the regions 41, 42. Accordingly; this can be used as a positioning part to finish the polishing operation. Thereby, a desired thin film can be polished accurately; an accurate polishing operation can be accomplished.
