| 20090025492 | APPARATUS FOR ADJUSTING POSITION OF VERTEBRAL COLUMN OF DUMMY MODEL FOR ESTIMATING FEELING OF SITTING IN SEAT - An apparatus for adjusting a position of the vertebral column of a dummy model for estimating the feeling of sitting in a seat almost exactly mimics the characteristics of the vertebral joints of a human being. The apparatus comprises a pelvic plate; a plurality of lumbar joints, stacked on the pelvic plate so as to be spaced apart from each other, and having joint springs installed in front and rear portions thereof centered around a rotation center interconnecting two adjacent ones thereof; femur joints rotatably installed below the pelvic plate, and connected with one end of each femur bar; and pelvic pivoting members transmitting rotating force of the femur joints, which is caused by vertical pivoting of the femur bars, to the pelvic plate, and changing a vertical angle of the pelvic plate. | 01-29-2009 |
| 20090056481 | PELVIS ASSEMBLY FOR DUMMY MODEL - A pelvis assembly for a dummy includes a pelvic plate attached to a lumbar region of the dummy, and one of more pelvic units, attached to the pelvic plate to transmit motion from a femur bar of the dummy to the plate. Each pelvic unit includes a hip joint, attached to the femur bar; a rotary axle, a first end of which is attached to the hip joint, and which is disposed laterally, to rotate together with the hip joint when the femur bar pivots vertically; and one or more pelvic angle adjusters, installed near a second end of the rotary axle, to transmit rotation of the rotary axle to the pelvic plate, thereby changing a vertical angle of the pelvic plate. | 03-05-2009 |

| 20100195065 | Exposure apparatuses - An exposure apparatus may include a light source generating light; a hologram mask, on which a hologram pattern is formed; and an optical unit movably disposed on the hologram mask to guide the light generated from the light source to the hologram mask. An exposure apparatus may include a light source generating light; a hologram mask, on which a hologram pattern is formed; a prism, separated from the hologram mask, such that one surface of the prism is disposed opposite the hologram mask; and a water supply device to supply water to a space between the prism and the hologram mask. | 08-05-2010 |
| 20100208226 | Holographic exposure apparatuses - A holographic exposure apparatus may include an object to be exposed, a holographic mask on which a pattern to be transferred onto the object is formed, a stage to support the mask, and a gap adjustment unit disposed between the mask and stage in order to move the mask relative to the stage. A holographic exposure apparatus also may include an object to be exposed, a mask spaced apart from the object, a holder that holds the mask, and a stage on which the holder is movably mounted such that a gap between the mask and object is adjusted. In addition, a holographic exposure apparatus may include a stage, a prism supported by the stage, a mask spaced apart from the prism and supported by the stage, and a gap adjustment unit disposed between the mask and stage in order to move the mask relative to the prism. | 08-19-2010 |
| 20100208316 | Holographic exposure apparatuses - A holographic exposure apparatus may include a main body, a mask stage supported by the body, a holographic mask supported by the mask stage, and a driving unit disposed between the body and mask stage. A holographic exposure apparatus may include an object supported by a substrate stage, a holographic mask spaced apart from the object and supported by a mask stage, a main body supported by the mask stage, and a driving unit disposed between the mask stage and body to control a gap between the mask stage and body. A holographic exposure apparatus may include a main body, a mask stage supported by the body, a holographic mask supported by the mask stage, and a piezoelectric element disposed between the body and mask stage. The body may include a support arm that supports the element. The mask stage may include a seat arm that supports the element. | 08-19-2010 |
