Abstract: PURPOSE:To obtain highly concentrated emulsion polymer dispersion having a large particle diameter, by emulsion-polymerizing vinylidene fluoride with the aid of a persulfate as a polymerization initiator in the presence of a specified fluoro-carboxylic acid (salt). CONSTITUTION:In emulsion-polymerizing vinylidene fluoride; use is made of, as a polymerization initiator, a persulfate[e.g., K2S2O8, (NH4)2S2O8], and to this polymerization system is added a fluoro-carboxylic acid or its salt represented by formulaIor II, wherein X is H, an alkali metal or an ammonium ion, m is 1-3 and n is 1 or 2[e.g., H(C2F4)COONa, H(C2F4)2COONH4, C3F7COONa or C3F7COONH4]. Since the number of polymer particle nuclei formed during the initial period of polymerization is controlled and the number of polymer particles becomes low, it is possible to obtain a highly concentrated emulsion polymer dispersion having a large particle diameter.

Title: Device for producing high-purity distilled water
Inventor: SHIYOUTAN SEIICHI
IPC: B01D1/30
Filed: 1989-05-26
Abstract: PURPOSE:To prevent intrusion of impurities by connecting a deaeration pipe to the upper end of a heating kettle and discharging steam from an evaporator through a filter permeable only to a gas. CONSTITUTION:The pure water in the heating kettle 1 is heated by a heater 9 and evaporated, and the vapor is introduced into the evaporator 13 via a connecting pipe 12. The pressure in the kettle 1 is increased due to the evaporation of pure water, hence the deaeration valve 31 is closed, and the unnecessary dissolved gas such as CO2 is discharged through the first deaeration pipe 30. The steam ascends in a columnar space formed by the inner wall of an inner cylinder 15 as a vortex, the steam collides with a collision plate 20 and a baffle 21, and the mist is removed. The steam is then introduced into a demister 23, and the deposition of condensed mist on the surface of the filter 24 is prevented. The purity of distilled water is improved in this way.

Title: Paper sheet feeding mechanism of character identification device
Inventor: KAWAMOTO TAKAHIRO
IPC: G06K13/103
Filed: 1987-05-29
Abstract: PURPOSE:To feed paper sheets one by one reliably by forming both the reverse roller and a picker roller in such forms as having the contacting faces with recessed and projected cross section, respectively. CONSTITUTION:A paper sheet 8 fed out of a pusher roller 3 goes between both a picker roller 4 having the recessed outline and a reverse roller 5 having the projected outline. At this time, the reverse roller 5 turns reversely to the transportation direction so that if two or more sheets 8 are fed out of the roller 3, the backing force is applied to the lower sheet. In addition, since the picker roller 4 in contact with the sheet 8 turns in the transporting direction, the sheet 8 is subject to the feed-out force. At this time, since the two rollers 4 and 5 have the concaved and the convexed face, respectively, the feed-out force against the sheet 8 acts more particularly in the opposing areas of the picker roller 4 when the sheet is fed out while the backing force acts more particularly in the middle area of the reverse roller 5.
