Provided is a fuel cell characterized in that a base material comprises a carbonaceous porous body having electrical conductivity in a part or the whole part and that a unit cell in which the respective layers of electrode/electrolyte/electrode are formed on the surface of the base material assumes a structure in which the base material is impregnated with liquid fuel (for example: methanol solution) and the surface of the electrode formed on the outside surface of the base material is exposed to air. The carbonaceous porous body having an electrical conductivity is allowed to have jointly functions as an electrode·collector, an impregnating medium for liquid fuel and oxidizing agent gas and a cell supporter, whereby a separator can be unneeded, and therefore a fuel cell which can reduce a size of a fuel cell system and which can exhibit a high output is provided by making use of the above unneeded space as a field for convecting and diffusing oxidizing agent gas or the liquid fuel.

[OBJECT] The object is to provide an applicator which enables substantially exact indication of the end state of the fluid to improve long-term use, convenience and the like and which can inhibit writing failures with a low cost, by preventing dew condensation. [MEANS FOR SOLUTION] An applicator includes: a rear barrel 1; an ink occlusion element 10 accommodated in rear barrel 1; an ink occlusion element receiver 20 opposing the front end part of ink occlusion element 10; a see-through front barrel 30 fitted to the opening of rear barrel 1, a detection tube 40 inserted in front barrel 30 for flowing ink from ink occlusion element 10; a joint core 50 supported by detection tube 40 and flowing out ink from ink occlusion element 10; and a pen core 60 supported by detection tube 40 and disposed on the opposite side of joint core 50 with a detection space 63 from joint core 50. Detection tube 40, joint core 50 and pen core 60 are formed into an integral structure. It is possible to exactly grasp the ink end state in a visual manner, based on the presence/absence of ink in detection space 63 of detection tube 40.
摘要:
A water-base white pigment ink for ballpoints comprising titanium oxide, a complementary colorant consisting of a pigment or a pseudo-pigment prepared by dyeing a particulate resin with a dye, a resin emulsion, a thickening agent, water, a polar solvent and other additives, in which the mean particle diameter of the pigment is 100 nm or above, that of the pseudo-pigment is 200 nm of above, and that of the resin particles of the resin emulsion is 200 nm or above, and which has a viscosity of 500 to 5000 mPa.s. This ink makes it possible to draw a clear line having a color tone equivalent to that of a poster color event across writing paper having a dark hue, is stable event after long-term storage, and can smoothly flow without interruption to permit continuous writing.
摘要:
Provided is a writing instrument in which a pen tip comprising a fibrous feed or a plastic feed is coated with a coating agent comprising a substance providing a cap-off property, wherein a fluorine base surfactant and/or a silicone base surfactant are added to an ink for the above writing instrument, and/or a substance which is solid at room temperature and has a solubility of 5 % or less in an ink solvent at room temperature and which has a polar functional group is added to the coating agent, whereby the writing instrument having an excellent cap-off performance can be obtained.
摘要:
A water-base ballpoint ink prepared, without using conventional water-soluble organic solvents which have been used for ink in the prior art, e.g., glycols, glycerin or glycol ethers, by adding at least one member selected from among reducing sugars mainly comprising maltitol, reducing sugars mainly comprising sorbitol, reducing dextrin, reducing maltodextrin, DOLLAR g(a)-cyclo-dextrin, DOLLAR g(b)-cyclodextrin and maltosylcyclodextrin as the componen t for protecting a ballpoint tip from drying, at least one member selected from among adducts of polyglycerol with alkylene oxides, adducts of glycerol with alkylene oxides and adducts of trimethylolpropane with alkylene oxides as the component for protecting drawn lines from feathering, improving the smoothness of ink flow, and retaining the lubricity thereof, and a viscosity modifier. The ballpoint ink gives good feelings in writing and is excellent in the smoothness of ink flow and the protection of a ballpoint tip from drying.
摘要:
Provided are an oil-based ink composition of a chromatic color having excellent stability with the passage of time, containing at least a colorant comprising a halochromic dye of a basic dye and an organic acid and an organic pigment, a butyral resin and an organic solvent and a ballpoint pen characterized by filling an ink reservoir with the above oil-based ink composition of a chromatic color.
摘要:
The writing instrument of the present invention having an excellent cap-off performance is characterized, as shown in, for example, Fig. 3, by that in a writing instrument 10 having a pen tip 13 comprising a fibrous feed or a plastic feed, the pen tip 13 described above is coated with a substance which is solid at room temperature and in which a solubility in an ink solvent is 10 % or less at room temperature among substances providing the pen tip with a cap-off property. This writing instrument 10 is such excellent in a cap-off performance that the good writing performance is obtained even after the pen tip is left standing in the air over a long period of time.
摘要:
Provided is a writing instrument having an ink tank part for storing ink, wherein an ink 11 contained in the ink tank part 31 comprises an ink component 12 and a layer-separative component 13 which separates to be a layer from the ink component 12; both of a specific gravity and a surface tension of the layer-separative component 13 are smaller than those of the ink component 12; and the ink 11 can freely move in the ink tank part 10. This provides a writing instrument and a liquid applicator which are excellent in visibility of an ink-remaining amount.
