IPC: G02B6/12
Filed: 1989-11-30
Abstract: PURPOSE:To improve mass productivity and to facilitate production by applying a UV curing resin as a core material having the refractive index higher than the refractive index of a clad part and having transparency on the surface of a base material and masking the region exclusive of the waveguide forming part on the surface of this UV curing resin and then irradiating the resin with UV rays. CONSTITUTION:The UV curing resin as the core material 2 having the refractive index higher than the refractive index of the clad part and having the transparency is applied on the surface of the base material 1 which is so formed that the surface thereof serves as the clad part. After the region exclusive of the waveguide forming part 2a on the surface of this UV curing resin 2 is masked 3, the UV curing resin 2 is irradiated with the UV rays and cured to form the waveguide 2'. The masking 3 and the uncured UV curing resin 2 are successively removed; thereafter, a clad material 5 consisting of the transparent material having the refractive index lower than the refractive index of the core material 2 is laminated over the entire part of the waveguide forming part.

Title: Solder-precoated wiring board
Inventor: EMA TOMIYO
IPC: H05K3/34
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent damage of solder precoating and generation of warp of a boad itself, when solder-precoated wiring boards are stacked for dealing, by arranging a plurality of dummy lands having an equivalent form to that of solder-precoated lands, on a waste board linked with the outer peripheral part of a mounting board. SOLUTION: A plurality of dummy lands 8 having equivalent thickness to that of solder-precoated lands 6 are arranged in symmetric positions on a waste board 4. When the solder-precoated boards 1 are stacked and dealed, the adjacent boards are put in the state that the board surfaces and solder-precoated lands 6 and the dummy lands 8 arranged around the lands 6 are pressed with an average pressure. It does not happen that, as in the conventional solder- precoated wiring board, the solder-precoated lands 6 are strongly scrubbed by the adjacent board, so that the lands 6 are scarcely damaged. A force warping the solder-precoated wiring board is not applied to the board, so that the board itself is not warped.

Title: Method of trimming roller plate material
Inventor: SUGITANI KUNITAKA
IPC: B21B15/00
Filed: 1990-11-14
Abstract: PURPOSE:To prevent interference between trimmed chips and a chute during trimming both ends of a strip to be rolled by a rolling mill, by pushing up both ends of the strip with the use of push-up rollers so as to form the strip into a dog-leg shape while shearing the same with the use of a trimming blade. CONSTITUTION:A strip S is conveyed toward a trimming blade 1, and when a cut-out part in a connected section of the strip S is detected by a connected part detecting device 5, a control device computes a time for shearing the connected part by the trimming blade 1, and delivers an instruction for elevating push-up rollers 4, to a hydraulic elevating device. Accordingly, the push-up rollers 4 are elevated up to a predetermined height, and accordingly, the widthwise ends of the strip S are pushed upward so that the strip is deformed into a dog-leg shape in a section orthogonal to the longitudinal direction. The strip S is fed to the trimming blade 1 in this condition. The deformation in such a dog-leg shape is reverse to the twisting direction of trimmed chips C, thereby it is possible to reduce the degree of twisting of the trimmed chips.

Title: Method and apparatus for enhancing distorted graphic information
Inventor: NUJIEHARII SANPASU JIYAYANTO
IPC: H04N5/14
Filed: 1994-12-14
Abstract: PURPOSE: To reduce a distortion effect by using an adaptive time and space post-filter equipped with a separable spatial and timely constituting element. CONSTITUTION: A time filter 110 and a space filter 112 are both adaptive. An output 114 of the filter 110 is connected with an input 116 of the filter 112. When a transmitted frame group 101 reaches a decoder 14, a sub-band decoder 100 generates a decoded frame 102. This frame group 102 is relatively distorted due to an error and/or other numerous factors at the time of transmission and/or quantization. Post-three waves in the form of the time post-filter and the space post-filter emphasize the sensing quality of the decoded frame 102. This is performed by generating a partially post-filtered frame group 103 from the filter 110, and this frame group is transmitted to the filter 112. The filter 112 outputs a frame group 104 re-constituted by obtaining the frame group 103, for example, a picture contrast matrix.
