Title: Three dimensional picture display method
Inventor: GOTO YOSHIHIRO
IPC: G06T15/08
Filed: 1986-11-25
Abstract: PURPOSE:To prevent a display picture from being deviated from an actual form as a visual point to a member 1 to be inspected approaches just above by displaying the longitudinal side of a rectangular voxel according to the change of the angle of elevation formed by a normal erected on a visual point surface with respect to a vertical plane to the longitudinal axis of the member to be inspected. CONSTITUTION:The spatial part of the rectangular voxel 4 is completely buried and displayed between contour points #1-#n and the three dimensional picture of the member 1 to be inspected is constituted and displayed. The length of the horizontal side La of the rectangular voxel 4 is defined to be constant and the length of the longitudinal side Lb is changed and displayed. Namely, the plane 5 vertical to the longitudinal axis (z) of the member 1 to be inspected, for instance, a body axis is defined to be one slice surface, the normal 7 is erected to the visual point surface 6 situated in a certain direction and an angle with respect to this slice surface, when an angle formed by the plane 5 when the normal 7 intersects with the center of the slice surface is defined to be the angle of elevation alpha, the horizontal side La is mode constant without depending on the angle alpha of elevation and the longitudinal side Lb is changed. The voxel 4 is a longitudinally long rectangle when the angle of elevation is small to the slice surface of the visual point surface 6, as the angle alpha of elevation becomes larger, the longitudinal side Lb grows small and it is a square when the angle of elevation is 90 deg..

Title: Photoscanning device
Inventor: SUZUKI TAKASHI
IPC: G02B26/10
Filed: 1985-12-12
Abstract: PURPOSE:To obtain an excellent image formation spot almost without any aberration even through a single lens by using such a single lens that the distance from the optical axis to the image formation position on a scanned plane is proportional to an angle of deflection and both surfaces are aspherical and rotationally asymmetrical as a scanning lens. CONSTITUTION:Luminous flux emitted by a light source is reflected by a mirror surface SM by an angle theta of deflection corresponding to the rotation of a polygon mirror 5. The scanning lens 1 is so set at a point III on the scanned plane where a coordinate value Y is proportional to the angle theta of deflection. The scanning lens 1 is such a single lens that the features of both aspherical surfaces S1 and S2 are utilized at high level, aberrations are small, and wide-angle deflection is possible. Namely, a curve is formed on a meridian plane, the inclination and curvature in the meridian plane attain the purpose of the scanning lens at an optional point on the curve, and the curvature of the cross section (sagittal cross section) which contains the main light beam and perpendicular to the meridian plane is obtained at the optional point on the curve. In this case, it is considered that the surface is formed.

Title: Production of stamper for optical disk
Inventor: MINEGISHI SHINJI
IPC: G11B7/26
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the thickness of a photoresist layer and to form low-height pits by preparing a photoresist soln. to a low viscosity. SOLUTION: The photoresist soln. diluted to a viscosity of <=4cP is applied by a spin coater on a glass master disk 1. This photoresist is baked at <=100 deg.C after application to form the photoresist layer 2 of a prescribed film thickness. The photoresist layer 2 is subjected to laser cutting by using an He-Cd laser or Kr laser. Next, the exposed parts 2a of the photoresist layer 2 are eluted by an alkaline developer to form groove parts which are pits. While the film thickness of the spin coated photoresist layer 2 is determined by the number of revolutions of the spin coater, the photoresist soln. has the viscosity as low as <=4cP and, therefore, the photoresist layer 2 is formable to the thinner layer in spite of the low number of revolutions of the spin coater.  Then, the low- height pits are formed and the manufacture of the stamper for optical disks dealing with a trend toward higher densities is made possible.

Title: Energy absorber installing structure
Inventor: SON MINE
IPC: B62D25/08
Filed: 1994-10-20
Abstract: PURPOSE: To provide an energy absorber installing structure by which a large crack running in the axial direction is not generated in an energy absorber at impactive collapsing deformation time and which can sufficiently absorb impact energy and does not exert adverse influence on an occupant. CONSTITUTION: Installing members 2 and 3 are connected to each other by flexible connecting rods 4, and are held on both ends of an energy absorber 1, and are installed on a car body or the like. Projecting parts 6 coming into line contact, point contact or partial surface contact with an inside hole 1b and/or the outer periphery of the energy absorber 1, are arranged on the installing member 2. Therefore, the energy absorber 1 is held in a right position. Since the projecting parts 6 come into line contact or the like with the inside hole 1b and/or the outer periphery of the energy absorber 1, a broken piece does not enter between the inside hole 1b and/or the outer periphery and the projecting parts 6. Therefore, a large crack running in the axial direction is not generated in the energy absorber 1 in a collapse advancing process.  Therefore, impact energy can be sufficiently absorbed.
