| 20110240401 | CARBONACEOUS ACOUSTIC DIAPHRAGM AND METHOD FOR MANUFACTURING THE SAME - A carbonaceous acoustic diaphragm whose density is reduced while retaining the required stiffness is provided. Carbon nanofibers and spherical particles of PMMA are mixed into a carbon-containing resin such as a polyvinyl chloride resin, and the mixture is carbonized to vaporize the spherical particles of PMMA, thereby forming a porous structure having pores with the carbon nanofibers in a powdered form uniformly dispersed through amorphous carbon. By forming a multilayer structure by combining the porous layer with a layer that does not use PMMA, the density can be further reduced while retaining the stiffness. | 10-06-2011 |

| 20110129288 | LIQUID APPLICATOR - The present invention is a liquid applicator which, in its assembled state an applying part, joint, and front barrel are fixed to a barrel body front end portion, the step of an indented/projected engaging portion on the inner peripheral side of the applying part rear end portion is abutted from behind against and engaged with the step of an indented/projected engaging portion on the outer peripheral side of the forward part of the joint. At the same time, an indented/projected engaging portion on the outer peripheral side of the applying part rear end portion is abutted against and engaged with an indented/projected engaging portion on the inner peripheral side of the front barrel's forward part, and an indented/projected engaging portion on the inner peripheral side of the front barrel rearward part is engaged with an indented/projected engaging portion on the outer peripheral side in the rearward part of joint, whereby applying part, joint and front barrel are formed so as to fix the applying part to barrel body by means of the joint and the front barrel. | 06-02-2011 |
| 20100297901 | COLORING COMPOSITION FOR PREVENTING SEE-THROUGH OF CLOTH, COLORING METHOD USING THE COLORING COMPOSITION AND CLOTH WHOSE BACK IS COLORED - The present invention relates to a coloring composition for preventing see-through of cloth which comprises, on the basis of the total mass of the composition, a pigment in an amount ranging from 0.002% by mass to 1% by mass; a polymer particulate dispersion; and water. | 11-25-2010 |
| 20100272496 | FLUID FEEDER OF APPLICATOR - To provide a fluid feeder of an applicator having a structure that allows a fluid to flow into a tubular member and be positively pressurized at the time of an ejecting operation, which can readily eject the fluid even if the fluid becomes unlikely to flow out and which allows the user to readily use over a long period of time even if a high-viscosity fluid is used. In the fluid feeder of an applicator, at the time of the closed state, the periphery of a base of a rod-like part comes into hermetic contact with the inner peripheral surface of a fore part of a tubular member. When the thrust against pressing end is weakened after an open state and then the fluid is pressurized before returning to the closed state, the plunger-like part is inserted into the cylinder surface so as to pressurize the fluid held in the space between the inner surface of tubular member and the outer surface on the front side of a step of a valve member, whereby the fluid is flowed out from an ejection opening that is in a state where the periphery of base of valve member is released from the inner peripheral surface of fore part of tubular member. | 10-28-2010 |
| 20100239942 | FUEL CELL - A fuel cell equipped with at least an air electrode side power collector layer, an air electrode catalyst layer, a polymer electrolyte membrane, a fuel electrode catalyst layer and a fuel electrode side power collector layer and provided with a porous body layer having a porous body at a liquid fuel side of the fuel electrode side power collector layer assumes a structure in which the porous body layer is provided with a gas flow velocity (superficial velocity in the layer) of 10 to 5000 cm/s at a differential pressure of 100 kPa. The porous body layer is a diffusion medium of a fuel into the fuel electrode catalyst layer and a discharge resistor of gases comprising carbon dioxide and steam which are electrode reaction products and a vapor of the liquid fuel in progress of electrode reaction. An interface of the gases and a gases layer are also provided. | 09-23-2010 |
