Solid phase synthetic methods of forming sulfur-linked disaccharides and oligosccharides are described, wherein a saccharide or oligosaccharide bearing a protected thiol-group at the anomeric carbon is immobilized onto a solid support at any position other than the anomeric carbon atom of the reducing sugar. The resultant immobilized thiol, or a derivative thereof, undergoes nucleophilic saccharide addition to provide a di- or oligosaccharide.

A housing contains a fuel cell, a lithium ion secondary cell, a wiring board on which a control circuit and the like are mounted, a light-emitting diode and the like. The bottom surface of the housing is covered with a bottom plate. A plurality of air-intake holes are formed in the bottom plate to supply air to the fuel cell. Two USB ports and are provided in the periphery of the housing. A plurality of air-discharge holes are formed in the upper portion of the periphery of the housing. Gas in the housing is discharged to the outside through the air-discharge holes. Furthermore, light from an LED provided in the housing works as an illumination for the fuel cartridge, which can facilitate checking of the fluid level of the fuel cartridge, thus, checking of the amount of remaining fuel.

PROBLEM TO BE SOLVED: To form an electrically conductive thin film formed of metal nanoparticles on various base materials at relatively low temperature in short time with simple procedures. SOLUTION: The electrically conductive film is formed by performing coating or patterning of an electrically conductive emulsion ink, which comprises an oil phase containing the metal nanoparticles and a water phase containing a reducing agent for the metal nanoparticles and/or a photocatalyst, on a base material surface, and then subjecting the ink to heat treatment and/or ultraviolet irradiation to reduce the metal nanoparticles. The heat treatment is preferably conducted at 40-100°C. The ultraviolet irradiation can be performed at room temperature. The oil phase comprises at least a non-aqueous dispersion medium and the metal nanoparticles dispersed in the medium. Preferably, the metal nanoparticles are obtained by the amine reduction method and coated with a protecting agent having a 10-20C linear/branched alkyl group. COPYRIGHT: (C)2011,JPO&INPIT

Electrically Conductive Emulsion Ink and Method for Producing Electrically Conductive Thin Film Using the Same

PURPOSE:To obtain an emulsion ink which includes a surfactant of a specific HLB in the oil phase and is composed of a water-in-oil type emulsion with its aqueous phase thickened, thus showing high emulsion stability at elevated temperatures and excellent temperature dependence of ink flowability and image quality. CONSTITUTION:The ink is composed of an emulsion having 10 to 50wt.% of the oil phase and 90 to 50wt.% of the aqueous phase where the surfactant in the oil phase has 3 to 5.5 HLB and the aqueous phase is thickened so that the viscosity reaches 15 to 350 poise, The surfactant is preferably a nonionic one such as sorbitan higher fatty acid ester. In order to thicken the aqueous phase a water-soluble polymer is added to the aqueous phase comprising water, electrolytes, a preservative, a fungicide and an evaporation retarder. The water- soluble polymer is, for example, an acrylic acid resin, or acrylic acid resin derivative such as sodium polyacrylate.

PROBLEM TO BE SOLVED: To provide a water-in-oil emulsion ink for stencil printing which has no odor, a good press stability, shelf stability, adhesion and solid filling in and little temperature dependence. SOLUTION: A water-in-oil emulsion ink comprising from 10 to 90 wt.% oil phase and from 90 to 10 wt.% aqueous phase contains a non-volatile mineral oil wherein the viscosity (at 40 deg.C) is larger than 10 mm2/s and, in a carbon distribution determined by ring analysis, the carbon content of the naphthene component is 34% CN or larger and the carbon content of the aromatic component is 20% CA or smaller.

PURPOSE: To obtain the subject ink having an arbitrarily adjustable color tone free from color separation, comprising a specific water-in-oil emulsion, by adding a water-soluble colorant to the water phase. CONSTITUTION: The objective ink comprising a water-in-oil emulsion composed of 10-50wt.% oil phase such as liquid paraffin and 90-50 wt.% aqueous phase and a water-soluble colorant (e.g. C. I. Direct-Yellowl) in the aqueous phase. Pigment (e.g. furnace carbon black) is preferably contained in the oil phase. COPYRIGHT: (C)1993,JPO&Japio

Emulsion ink for perforated plate printing

PROBLEM TO BE SOLVED: To provide emulsion ink for mimeograph printing, which is water in oil type (W/O type) emulsion ink capable of being colored at least with a green color, without elevating viscosity and also without causing the separation and degeneration of the ink even in its preservation at a high temperature, and without generating harmful substances on its incineration. SOLUTION: This emulsion ink for the mimeograph printing is provided by containing 10-90 mass% oil phase and 90-10 mass% aqueous phase and a coloring agent in at least any of the oil phase and aqueous phase, in which the coloring agent consists of a blue-coloring agent and yellow-coloring agent.
