20120309577 | REVOLVING APPARATUS FOR CONSTRUCTION MACHINE - An electric motor is arranged on a reduction device, and a wet braking device which gives braking force to a motor shaft is arranged on an upper end side of the electric motor. The wet braking device has a brake case which accommodates an upper end portion of the motor shaft, an adapter which is detachably disposed to the motor shaft in the brake case, a plurality of rotating side brake disks and a plurality of non-rotating side brake disks arranged on an outer peripheral side of the adapter and a brake piston which gives braking force to the motor shaft by frictionally engaging the rotating side brake disks and the non-rotating side brake disks with each other. At the time of performing a maintenance operation for the wet braking device, the wet braking device alone can be solely removed while keeping the electric motor assembled to the reduction device. | 12-06-2012 |
20130180809 | WET BRAKE DEVICE - A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided only on the non-rotating side brake disk in these rotating side brake disk and the non-rotating side brake disk. As a result, the weight of the rotating side brake disk can be reduced, and drag resistance of the rotating side brake disk rotating also in brake release can be reduced. | 07-18-2013 |
20130248303 | WET BRAKE DEVICE - A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided on the non-rotating side brake disk, and an oil groove is provided in a frictional engaging surface of this frictional material. It is configured such that, when a braking force is applied by a brake piston to the motor shaft, lubricant oil flowing into the brake case from a lubricant oil inlet port flows from the outer diameter side to the inner diameter side between the rotating side brake disk and the non-rotating side brake disk only through the oil groove. As a result, the lubricant oil having flowed into the brake case efficiently cools the frictional engaging surface. | 09-26-2013 |

20100143184 | METHOD FOR MANUFACTURING METAL NANORODS AND USE THEREOF - A method for manufacturing metal nanorods includes: a step of adding a reducing agent to a metallic salt solution; a step of radiating light into the metallic salt solution containing the reducing agent; and a step of leaving the light-radiated metallic salt solution containing the reducing agent stationary in a dark place so as to grow metal nanorods. Metal nanorods can be also grown by forming a mixed solution by fractionating the above light-radiated metallic salt solution and mixing the fractionated metallic salt solution into a non-radiated metallic salt solution containing the reducing agent, or mixing a non-radiated metallic salt solution and the reducing agent into the above light-radiated metallic salt solution; and leaving the mixed solution stationary in a dark place so as to grow metal nanorods. | 06-10-2010 |
20100229684 | METAL FINE PARTICLES, COMPOSITION CONTAINING THE SAME, AND PRODUCTION METHOD FOR PRODUCING METAL FINE PARTICLES - The present invention provides metal fine particles which have selective wavelength absorption characteristics in a wavelength region from visible light to near infrared light, and have sharp absorption characteristics, and influences little the surrounding wavelength, and therefore, they yield tones having high chroma. The present invention provides metal fine particles wherein an aspect ratio is in a range from 1.1 to 8.0, a maximum absorption wavelength in plasmon absorption is in a range from 400 nm to 1,200 nm, and an absorption coefficient at a peak position of the maximum absorption wavelength is in a range from 6,000 to 20,000 L/mol·cm (measurement concentration: 1.6×10 | 09-16-2010 |
20120329123 | METHOD FOR DETACHING CULTURED CELLS, CELL DETACHMENT DEVICE USED IN SAID METHOD FOR DETACHING CULTURED CELLS, AND INCUBATOR - Disclosed is a method for detaching cultured cells that can selectively detach cultured adhered cells. The scaffold to which the cells adhere is configured from at least a cell adhesion factor containing carbon nanotubes, and by means of radiating laser light in a spot shape on the scaffold in a region where cells are adhered, a shock wave is generated by the heat arising by means of the photothermal conversion of the carbon nanotubes, and by means of this shock wave, the cells are caused to be in a non-adhered state. | 12-27-2012 |
