| 20120217705 | SLIDING MEMBER - An annular sliding member which is used in a mechanical seal, is attached to a rotating shaft, and slidably comes into contact, by being applied with energizing force in the axial direction, with another annular sliding member attached to a housing, wherein the sliding surface which comes into contact with the other sliding member is formed from: a dynamic pressure generating groove which guides a fluid to be sealed from a region to be sealed to the side of a region to not be sealed of the sliding surface, and a concave-convex section configured from a plurality of minute grooves which have a shallower depth than the dynamic pressure generating groove. | 08-30-2012 |
| 20140167361 | MECHANICAL SEAL - A mechanical seal has a structure wherein a plurality of sealed-fluid-accommodating blocks separated in the circumferential direction are formed on either the sealing face of a fixed ring or the sealing face of a rotating ring so as to communicate with a sealed fluid accommodation space. Pumping parts for creating a pumping action due to the fixed ring and the rotating ring sliding while undergoing relative rotation are formed on a bottom part of the plurality of sealed-fluid-accommodating blocks. The pumping parts formed on the bottom parts of the plurality of sealed-fluid-accommodating blocks are provided with an intake pumping part which acts in a direction in which the sealed fluid is drawn in and a discharge pumping part which acts in a direction in which the sealed fluid is discharged. | 06-19-2014 |
| 20140217676 | SLIDING PARTS - Sliding parts are provided where a plurality of dynamic pressure-generating grooves for generating dynamic pressure via the relative rotational sliding of the stationary ring and the rotating ring are formed in a circumferential direction on a sealing face of one of a stationary ring and the rotating ring so as to communicate with a sealed fluid-containing space, and pumping areas for generating pumping action via the relative rotational sliding of the stationary ring and the rotating ring are formed within the dynamic pressure-generating grooves. | 08-07-2014 |
| 20150014938 | BRUSH SEAL - A brush seal includes a bristle part formed by multiple bristles attached to a stationary part between the stationary part and a rotational part that undergo relative motion by maintaining a space in between; and a back plate attached adjacent to the bristle part on its low-pressure side to restrict the movement of the bristle part. The brush seal for sealing a fluid between the stationary part and rotational part is characterized in that the bristle part is formed by the multiple bristles such that the multiple bristles arranged in a direction of fluid are mutually fixed between a base end and a free end to form planar bristles arranged continuously in layers in a circumferential direction to form the bristle part. | 01-15-2015 |
| 20150014939 | BRUSH SEAL - A brush seal includes a bristle part formed by multiple bristles attached to a stationary part between the stationary part and a rotational part that undergo relative motion by maintaining a space in between and a back plate to restrict the movement of the bristle part. Such brush seal for sealing a fluid between the stationary part and the rotational part includes the bristle part formed by the multiple bristles such that the multiple bristles arranged in a direction of pressure difference between the high-pressure side and the low-pressure side are mutually fixed between a base end and a free end to form planar bristles, and these planar bristles are arranged continuously in layers in a circumferential direction to form a circular bristle part, wherein circumferential grooves are formed on the sliding surface of the bristle part on its free end side. | 01-15-2015 |
| 20150042045 | SLIDING COMPONENT - Provide a sliding component that reduces the leakage rate of sealed fluid and significantly improves the lubrication characteristics at startup or stop, while being actuated by means of fluid lubrication in the rotation phase, thereby achieving the effects of sealing and lubrication at the same time. The sliding component is characterized in that: on one sealing face of a pair of sliding parts that slide relative to each other, multiple positive pressure-generating mechanisms that comprise extremely shallow parallel grooves running roughly in parallel with the sealing face and having submicron-level height differences are provided independently in the circumferential direction; the extremely shallow parallel grooves connect to the high-pressure fluid side, but are isolated from the low-pressure fluid side by a seal area; and extremely shallow thin grooves are formed at the bottom of the extremely shallow parallel grooves. | 02-12-2015 |
| 20150084286 | SLIDING COMPONENT - A sliding component is characterized in that, on one sealing face of a pair of sliding parts that slide relative to each other, multiple positive pressure-generating mechanisms that include extremely shallow parallel grooves running roughly in parallel with the sealing face and having submicron-level height differences are provided independently in the circumferential direction, and that extremely shallow thin grooves are formed on the sealing face on the low-pressure fluid side of the extremely shallow parallel grooves, wherein the extremely shallow parallel grooves communicate with the high-pressure fluid side, and the extremely shallow thin grooves communicate with the extremely shallow parallel grooves, but are isolated from the low-pressure fluid side by a seal area, thereby reducing a leakage rate of sealed fluid and significantly improving lubrication characteristics at startup or stop at the same time. | 03-26-2015 |

| 20140128799 | PHOTODYNAMIC THERAPY USING PHOTOSENSITIZING AGENT OR 5-AMINOLEVULINIC ACID - It is to provide photodynamic therapy (PDT) and photodynamic diagnosis (PDD) which are suitable for the diagnosis and therapy of a part requiring a certain degree of deep penetration, such as subcutaneous cancer and lymph nodes surrounded by blood vessels and fat. This is solved by performing PDT and PDD targeting cancer by administering a composition comprising a photosensitizing agent such as a tetrapyrrole-based compound (photofrin, protoporphyrin IX, etc.) or ALAs such as 5-aminolevulinic acid (ALA), ALA methyl ester, ALA ethyl ester, ALA propyl ester, ALA butyl ester, ALA pentyl ester, or a hydrochloride, phosphate, or sulfate thereof followed by irradiation with excitation light at a wavelength of 480 to 580 nm. | 05-08-2014 |
| 20140188034 | THERAPEUTIC AGENT FOR ALLERGIC RHINITIS - Provided is a therapeutic agent capable of treating allergic rhinitis in a safe, simple, and noninvasive manner substantially without side effects and physical distress to patients. Provided is a therapeutic agent for allergic rhinitis for 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) comprising 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt of the 5-aminolevulinic acid or the derivative as an active ingredient, and used in ALA-PDT in which light having a wavelength of 400 nm to 700 nm is irradiated; and particularly provided is a therapeutic agent for allergic rhinitis in a locally applied solution form, a water-soluble ointment-dissolved form, a jelly-dissolved form, or the like. The therapeutic agent does not require the conduct of 5-aminolevulinic acid-based photodynamic diagnosis (ALA-PDD) for detecting a site of protoporphyrin IX (PpIX) accumulation radiating light having a wavelength of 610 nm to 650 nm under irradiation of excitation light having a wavelength of 380 nm to 420 nm before ALA-PDT. | 07-03-2014 |
