| 20090038150 | METHOD FOR PRODUCING COMPRESSOR, AND COMPRESSOR - A method for producing a compressor comprises an aligning step and a welding step. The compressor includes a casing and an inside part that is housed in the casing. The casing includes a first portion on its inner surface, and the inside part includes a second portion. The second portion faces the first portion. In the aligning step, the first portion and the second portion are caused to face each other. In the laser welding step, laser light is applied to at least part of the portion where the first portion and the second portion face each other, whereby the casing and the inside part are laser-welded together. | 02-12-2009 |
| 20090068046 | COMPRESSOR AND MANUFACTURING METHOD THEREOF - The compressor includes a first constituent element and a first slider. The first constituent element is capable of being laser welded. The first slider is composed of cast iron capable of being laser welded and having a carbon content of from 2.0 wt % or more to 2.7 wt % or less. This first slider is joined to the first constituent element by laser welding without using a filler. | 03-12-2009 |
| 20100061871 | COMPRESSOR SLIDER, SLIDER PREFORM, SCROLL PART, AND COMPRESSOR - A compressor slider has a carbon content of 2.0 wt % to 2.7 wt %, a silicon content of 1.0 wt % to 3.0 wt %, a balance of iron that includes unavoidable impurities, graphite that is smaller than the flake graphite of flake graphite cast iron, and a hardness that is greater than HRB 90 but less than HRB 100 in at least a portion of the slider. | 03-11-2010 |
| 20100284844 | METHOD FOR MANUFACTURING COMPRESSOR SLIDER, AND COMPRESSOR - A method for manufacturing a compressor slider includes a slider preform manufacturing step, a resin coating step, and a machining step. In the slider preform manufacturing step, an iron slider preform in which at least one property selected from the tensile strength and the tensile modulus of elasticity is greater than that of flake graphite cast iron is manufactured using a prescribed mold. In the resin coating step, the slider preform is not machined, but the resin coating layer is formed on all or a part of the slider preform. In the machining step, only the resin coating layer is machined, and a completed slider is obtained. | 11-11-2010 |

| 20100208209 | OPTICAL APPARATUS AND PROJECTION TYPE IMAGE DISPLAY APPARATUS - An optical apparatus includes a frame, having optical components, mounted on a casing by means of an auxiliary member. The casing is provided with a groove in which the frame is inserted and a mount section to which a first part of the auxiliary member is fixed. The frame is provided with a frame-side positioning section engaged with a second part of the auxiliary member when the frame is inserted in the groove and then set at a predetermined angle of rotation. The auxiliary member is provided with the first part fixed to the mount section of the casing and the second part engaged with a frame-side positioning section. The first and the second part of the auxiliary member are formed in positions separate from each other while the second part is engaged with the frame-side positioning section under the elastic force of the auxiliary member. | 08-19-2010 |

| 20100141900 | LIGHT SOURCE DEVICE AND PROJECTOR - A lamp unit configuring a light source device capable of efficiently cooling a light source by a simple structure includes a light source and a plurality of air outlets for discharging the cooling air for cooling the light source. The plurality of air outlets include a first air outlet for discharging the cooling air in a first direction and a second air outlet for discharging the cooling air in a second direction. The cooling air discharged through the first air outlet is different in airflow rate from the cooling air discharged through the second air outlet, and the first direction is different from the second direction when viewed in the direction of the optical axis of the light source. | 06-10-2010 |
