Title: Alkali water maker
Inventor: TSURUTA KUNIHIRO
IPC: C02F1/68
Filed: 1984-10-18
Abstract: PURPOSE:To obtain alkali water without using a power source by housing a filter packed with the solid basic substance contg. Mg or MgO into a retention vessel in providing the clearances. CONSTITUTION:A filter 7 packed with the solid basic substance 6 contg. Mg or MgO is housed into a retention vessel 8 in providing the clearances. By this constitution, alkali water can be obtained without using a power source. There is no dirt in water and the elevation of pH is maximumly reached to 10 and water can be made to weak alkalinity. Furthermore since the chemical reaction is mild, the daily dissolving quantity of Mg or MgO is remarkably slight and it can be used for a long period and the formation of residue such as magnesium hydroxide is little and the handling is easy.

Abstract: PROBLEM TO BE SOLVED: To quickly confirm and process a scanned image by the terminal of each one without lowering job efficiency by storing the relation between document type data and a transfer destination address, deciding the transfer destination address of image data and transferring the image data to the transfer destination address. SOLUTION: Read image data is successively stored in a buffer memory 26, and a document type identifying part 33 identifies a document type. The part 33 fetches document identification symbol data and document identification IDs registered in an ARDB 41 from the ARDB 41 and discriminates whether a document type ID coinciding with the extracted identification symbol data exists. The part 33 transmits the coinciding document type ID to a transfer controlling part 40 when the document type ID coincides as a result of the discrimination. The part 40 refers to the data of the ARDB 41, determines a transmission destination address corresponding to the received document type data and transfers the image data to each client terminal on the basis of an address where the image data is determined.

Abstract: PURPOSE:To press a carrier plate uniformly and machine the surface of a polishing material into a specular surface with high accuracy by providing an elastic member for horizontally pushing back the inclined condition of a pressing board for pressing the top of the carrier plate on a supporting shaft. CONSTITUTION:A supporting shaft 17 is depressed at a defined pressure pressing a carrier plate 12 downward by means of a pressing board 13 which is rotatably and inclinably provided on the supporting shaft 17 to press a silicon wafer 11 against the top of a surface plate 10, thereby, polishing the bottom face of the wafer 11 by the rotation of the surface plate 10. At this time, the pressing board 13 together with the carrier plate 12 tends to be inclined downward in the advancing direction of the rotation of the surface plate 10 due to the polishing resistance of the silicon wafer 11 which is in contact with a polishing surface. However, the pressing board 13 is horizontally returned due to the elastic force of a spring member 18 which is interposedly provided in the supporting shaft 17 and is rotated maintaining a horizontal condition. Hence, the silicon wafer which is stuck to the bottom face of the carrier plate 12 is uniformly pressed against the surface plate 10, and finished into a flat specular surface without inclination with high accuracy.

Title: Decorative part for timepiece or the like with stone clamping claw for decoration and its manufacture
Inventor: OHIGATA YUICHI
IPC: G04B45/00
Filed: 1989-08-28
Abstract: PURPOSE:To enable mass-production by obtaining a stone clamping claw for decoration with >=94% relative density after sintering by a metal powder injection molding method which uses stainless steel powder as a raw material. CONSTITUTION:A green molding formed integrally with a timepiece-side main body 1c by injection molding is passed through a degreasing and sintering process to become a stainless-steel metal blank. At this time, metal powder grading, binder, degreasing, and sintering conditions, etc., are selected properly to secure >=94% relative density. Then rough polishing and intermediate polishing are carried out by barrel polishing. This is carried out by exactly the same method with the clamping to stone clamping noble metal. Namely, a lower hole for stone setting is chamferred so as to absorb an irregularity in stone height and the claw is bent with the same tool with the noble metal clamping to clamp a stone. In this case, the claw which stands upright at 90 deg. after molding and has a phi0.3mm diameter and 0.6mm height is bent from its base up to 50 deg. with a slight 4kg force and the quantity of deformation which is enough to clamp the stop is obtained manually with a deforming level which enables mass- production.
