Title: Method for temporarily damping lens mold piece for reducing lens hole defect in manufacture of contact lens
Inventor: MAIKERU UIDOMAN
IPC: B29D11/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce a lens hole or a paddle flaw by temporarily coating one of the surfaces of both mold pieces with a chemical agent to enhance the wettability of the surface of the coated mold piece to a reactive monomer mixture. SOLUTION: A recessed mold piece has a flange bringing the surface for forming the optical surface of a lens and a projected mold piece into engagement with each other. After the recessed mold piece is passed through a registering and arranging station, the flange part of the mold piece is treated with a surfactant so that the surfactant does not come into contact with the optical surface of the mold piece. Subsequently, the recessed mold piece is filled with a reactive monomer mixture at a filling and assembling station 50 and matched with the projected mold piece so as to form pair. The assembly of the paired mold piece is pre-cured in a pre-curing module 60 and polymerization is completed in a curizing zone 75 and the mold pieces are separated by a mold piece separation device 90.  At this time, an excessive lens material is separated from a lens blank by the surfactant of the recessed mold piece to be held to the projected mold piece.

IPC: C23C14/34
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To average erosion, to prolong the life of a target and to enhance the utilization efficiency of the target by packing a low m.p. metal into the part where the target material is eroded. SOLUTION: When the erosion of the target 22 formed of the target material progresses, the surface of the target 22 is partially eroded and an eroded part 27 as if a hole is drilled is generated and the bottom of the eroded part 27 arrives at a backing plate 21. The low m.p. metallic material consisting of the metal of the compsm. component of the target material such as, for example, indium or tin or its alloy, or the alloy thereof is dissolved and the low m.p. metal 28 is packed into the eroded part 27 formed in such a manner. As a result, the backing plate 21 is sputtered in the eroded part and the formed material thereof is prevented from forming a film on a substrate. Even if the target life runs out, the low melting metal is packed into the eroded part and the further sustained use of the target 22 is possible.

Title: Fault diagnostic method
Inventor: OKOCHI SATOSHI
IPC: G06F11/22
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To prevent a wrong fault diagnosis in consideration of fault diagnostic results of all electronic devices. SOLUTION: The objective electronic devices are diagnosed successively. A ROM is diagnosed first (102) and its diagnostic result is stored (104). Then a font ROM is diagnosed (106) and the diagnostic result is stored (108). Further, a DRAM is diagnosed (110) and the diagnostic result is stored (112). Even if a diagnostic result indicating abnormality is obtained halfway, all the electronic devices are thus diagnosed without any interruption, so the diagnostic results of all the electronic devices can be obtained and such inaccurate diagnostic results that only an electronic device whose error is diagnosed first is considered to be abnormal although more than one electronic devices get out of order can be evaded.

Title: Production of two-dimensional data from three-dimensional cad standard data
Inventor: SEKI MAKI
IPC: G05B19/4097
Filed: 1991-09-30
Abstract: PURPOSE:To selectively produce only the NC data on a desired part by acquiring the two-dimensional data on an optional projecting direction from the given three-dimensional CAD standard data. CONSTITUTION:The data on the ruled line vectors and the dots which prescribe a projection plane pi0 and the area designating planes pi1-pii are set and inputted via a keyboard 3. Then a projection subject area V enclosed by the planes pi1-pii and the plane pi0 are calculated by the arithmetic processing of a CPU 1. Only the shape elements included in the area V are orthogonally projected on the plane pi0 among those shape elements on the three-dimensional CAD standard data which are read into a RAM 2. Thus the three-dimensional projection data on each shape element is obtained. Then the two-dimensional data that define the plane pi0 as an X-Y plane are obtained from each of three- dimensional projection data and stored in the RAM 2 or a data base of a floppy disk 9. The NC data producing function of the CPU 1 is actuated to the two- dimensional data produced with designation of the projecting direction and the area V. Thus it is possible to produce only the NC data on a necessary part set on the basis of a desired projection plane.

Filed: 1987-10-30
Abstract: PURPOSE:To effectively hold a centered state and to fix an optical fiber in a package by centering a laser diode and the optical fiber and then using a microscope used for said centering. CONSTITUTION:The system is provided with the microscope 21 for observing the optical fiber 11 and the laser diode package 15 and a laser source for supplying laser energy for fixing the fiber 11 on the package 15. Centering is executed so that light from the laser diode 14 in the package 15 can be efficiently made incident on the fiber 11 and laser energy is focused on a fixed position on the screen of the microscope. The fixed position is moved to a fixed point of the fiber 11 in the package 15 and then laser energy is radiated to fix the fiber 11 on the package 15. Consequently, accurate positioning can be attained and the optical fiber 11 can be prevented from being shifted due to thermal distortion generated at the time of fixing.
