Title: Narrow-band electric discharge pumping laser device
Inventor: TAKAHASHI HIDEMI
IPC: H01S3/1055
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a polarized light separating mirror by reducing the light intensity load to the mirror by placing the mirror on the position where a beam is magnified by means of a prism. SOLUTION: The deterioration of and damage to the polarized light separating film of a polarized light separating mirror 2 are caused by the electric field strength of light at a multilayered film. Since the pulse width of an excimer laser is as short as 10-20 ns, the electric field strength of light is high and an element is apt to be deteriorated and damaged. This means that the more the energy density of light increases, the more the polarized light separating film is deteriorated or damaged. Therefore, the mirror 2 is constituted so that a beam 101 which is magnified in beam size through a prism 31 may be made incident to the mirror 2. When, for example, the magnification of the prism 31 is triple, therefore, the beam intensity (power density per unit area) at the mirror 2 is reduced to 1/3.  Since the beam intensity is reduced, the deterioration of and damage to the mirror 2 are suppressed and the service life of the mirror 2 is prolonged.

Filed: 1989-12-01
Abstract: PURPOSE:To attain high speed access by providing a lens including a face of diffraction grating structure, a light source whose oscillating wavelength is varied, and an actuator moving the light source in the optical axis direction. CONSTITUTION:A micro Fresnel lens 102 is formed to the face of a lens 101 and parameters such as curvature and refractive index of the face of the lens 101 including the lens 102 are selected so that the divergence light from a wavelength variable semiconductor laser 103A is made converged to a spot 104A.

Besides, the corner part of the trench is cut off, and it becomes the orientation of (110). The film thickness of the sidewall of the trench and the bottom face of the gate insulating film 15 are almost same, and the film thickness at the corner part KB is thicker than the film thickness of the bottom face. Accordingly, the lowering of dielectric resistivity of the trench bottom part and the breakdown of the gate insulating film can be suppressed.

Filed: 1990-11-21
Abstract: PURPOSE:To enhance easiness in inserting a control rod, secure the water zone, simplify the shuffling procedures for fuel aggregate, and provide possibility of enlarging the fuel aggregate by furnishing a cruciform cylindrical arrangement surrounding a control rod. CONSTITUTION:A cruciform cylindrical arrangement 2 surrounding a control rod 3 is provided in a lattice-shaped space formed by a fuel upper part lattice plate 1 and a lower part lattice plate. This cylindrical arrangement 2 forms a guide surface for the rod 3 and also secures a water zone.

In this manner, the cylindrical arrangement 2 serves as a channel box for fuel aggregate, so that such a box is no more needed particularly to contribute to reduction of materials used. Because the cylindrical arrangement 2 is left at the time of shuffling of the fuel aggregate, the rod 3 will not tumble, even though all aggregate in the four parts is removed, and the working procedures can be simplified. The fuel aggregate not having any channel box to be inserted in space quadri-divided by the cylindrical arrangement 2, can be embodied in a large sized.

Filed: 1993-11-22
Abstract: PURPOSE:To decrease speckle noises while maintaining interference for hologram formation even if a holography technique is applied by moving the optical element disposed in the optical path of the optical device in the state of maintaining its optical surface. CONSTITUTION:The optical surface 13 of a plane mirror 10 is provided with a driving part 14 to permit movement of this plane mirror 10 back and forth in a direction A. A reference opposite surface 11 for moving the optical surface of the plane mirror 10 while maintaining the state of the optical surface is disposed and the optical surface 13 is maintained in the state of pressing the optical surface from behind via a bearing 12. As a result, the optical surface 13 moves parallel according to the reference opposite surface 11, by which the optical surface 13 is maintained. Then, the influence of the movement of the plane mirror on the optical path and wave front of the luminous flux after reflection does not arise. The dust, etc., on the optical element move and the scattered light change according to the movement. The speckle patterns caused by the scattered light, therefore, move according to the movement of the plane mirror 10 and the stationary appearance of the speckle noises is averted.

Title: High load transmission belt
Inventor: TAKAGI SHINICHI
IPC: F16G5/16
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To lengthen the service life of a belt, and to reduce weight by forming a block as the belt by covering a periphery of a reinforcing material with a resin, arranging the reinforcing material at least in a beam part, and without practically arranging the reinforcing material in side pillars and lock parts. SOLUTION: An aluminum alloy and steel are cited as a reinforcing material 13 constituting a block 5, and a resin 14 to cover the reinforcing material 13 is formed of a reinforced resin which has a comparatively large friction coefficient and is excellent in abrasion resistance and in which woven fabric such as chemical fiber and glass fiber and a filler are mixed by using hard rubber, a hard polyurethane resin having higher rigidity than elastomer constituting a center belt. The reinforcing material 13 is arranged only in a beam part 8, and it is formed without arranging the reinforcing material 13 in side pillars 6 and 7 and lock parts 11 and 12. Therefore, the side pillars 6 and 7 is easily elastically deformable, and absorb most of stress even if lateral pressure is applied from a pulley, and can prevent damage of the block.  A boundary 15 between the beam part 8 and the side pillars 6 and 7 can be reinforced, and weight of the block can be reduced.
