Title: Forming die for plasma display panel back plate and forming method of back plate
Inventor: MATSUZAWA HIROSHI
IPC: H01J11/34
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To facilitate enlargement of a screen by obtaining barrier ribs high in dimensional accuracy and uniform in height, by alternately layering plates of the same thickness as the barrier ribs and plates of the same thickness as the width of cells and causing the plates of the same thickness as the width of the cells to project by the height of the barrier ribs to form groove parts in stripes. SOLUTION: Metallic plates A of the same thickness as barrier ribs and metallic plates B of the same thickness as the width of cells are machined into linear shapes, and the metallic plates A and the metallic plates B are alternately placed one on another. This is fixed so that no gaps are produced and that linearly machined edges of the metallic plates B uniformly project, thus forming a stripe forming die. Groove parts in the stripe forming die so obtained are filled with a paste-like barrier-rib forming material comprising a low melting-point glass powder, a butyral resin, a solvent, a dispersant, etc., and this is bonded under pressure to a glass substrate fitted with electrodes. Then, the stripe forming die is peeled off.  The glass substrate with a barrier-rib molding thus formed thereon is retained at a fixed temperature to remove a binder and baked, thus forming desired barrier ribs of good shapes.

IPC: G11B5/39
Filed: 1989-06-28
Abstract: PURPOSE:To decrease noises by forming the thickness of the electrode film near a track width to a gently tapered thickness, providing a bias means thereon and varying the distance between the bias means and a magneto-resistance effect element. CONSTITUTION:The element and the bias means are near in the track width part when the means for biasing is formed on the gentle electrode 6 via an insulating film 9; therefore, a sufficient DC bias magnetic field is impressed and high output is obtd. On the other hand, the element and the bias means part when the element and the bias means part from this part; therefore, the bias magnetic field lowers and the output lowers. The noises from the parts exclusive of the track width part are decreased in this way. Since the sectional area of the electrode patterns is increased, the resistance in the electrode part is lowered and the contribution of the electrode layer occupying the resistance over the entire part of the head is extremely minimized. The thermal noises of the heads are thus decreased.

Abstract: PURPOSE: To analyze a sample regarding different tests of a wide range without adding a treating stage during analyzing of the sample with high reliability at an evaluation curve by designating an input variable to one of subsections, and thereby conducting several types of operations to obtain the correlation with specific concentration. CONSTITUTION: The effective designation of ambiguous evaluation curve C=f (X) to a subsection can be conducted by adding specific input variable introduced from the change S(t) of the time dependence of a measured amount S.

To raise the analyzing accuracy, it should be remarkably altered as the function of the concentration C as much as possible. In case of measuring turbidity, the end point value of the turbidity, the value of plateau and maximum change rate are normally used. As several types of operations, the concentration calibration is accurately conducted by a training operation, and the analyzing operation includes the designation of a calibration curve X=f<-1> (C) to the subsection.

IPC: G02B6/26
Filed: 1986-07-16
Abstract: PURPOSE:To reduce insertion loss and to obtain uniform branching characteristics by composing an optical branching and coupling element of a branch-shaped internal layer which extends in the axial directions of pleural optical fibers and an external layer covering it, and decreasing the refractive index from the internal layer successively. CONSTITUTION:This element consists of the internal layer 13 which connects the optical fibers 10-12, an intermediate layer 14 formed at its outer periphery, an external layer 15 formed at the outer peripheries of the fibers 10-12, and matching layers 16-18 provided between the fibers 10-12 and layer 13. The refractive index of the layer 14 is between the refractive indexes of the layers 13 and 15. In this constitution, even if there is interface mismatching between the layers 13 and 14 and light is transmitted through the light 14, the light is reflected totally by the interface between the layers 14 and 15, so the light is propagated in the layer 13 again. Thus, the light loss is reduced. Further, the layers 16-18 are provided to reduce the coupling loss between the optical fibers and optical branching and coupling element and then reduce the light loss. Consequently, the uniformity of light output between output ports becomes superior.
