Title: Production of liquid crystal panel
Inventor: TATSUTA SUMITAKA
IPC: G02F1/13
Filed: 1990-06-29
Abstract: PURPOSE:To shorten the process time for injecting a liquid crystal into the panel by reducing the air pressure in the panel through an aperture, then injecting a liquid crystal material into this aperture or an aperture provided separately therefrom. CONSTITUTION:A band-shaped sealing material 2 has at least one apertures penetrating the inside and outside of a panel gap in the case of injection of the liquid crystal material. The pressure reduction is started in such a manner that the air pressure in the panel is equal to or lower than the air pressure on the outside of the panel through this aperture 5, by which the pressure at least in the panel is reduced; thereafter the liquid crystal material is brought into contact with the aperture 5 or the aperture provided separately therefrom to inject the liquid crystal material into the panel. Only the pressures from both sides act always on the substrate 1 surface of the cell at this time and the expansion pressure does not act thereon and, therefore, the inside of the cell can be evacuated without peeling of microadhesive points 3. The pressure reduction is executed in a short period of time in this way without breaking the adhesive points.

Title: Electrode feed speed correcting device for electrolytic processing machine
Inventor: KONDO MORINOBU
IPC: B23H3/02
Filed: 1986-07-23
Abstract: PURPOSE:To hold a gap between processing electrodes at a proper value, by a method wherein, when a change factor of a current flowing through the gap between the processing electrodes exceeds the upper limit of a preset allowable range, the feed speed of the processing electrode is decreased, and when it is below a lower limit, the feed speed is increased. CONSTITUTION:Based on a voltage, regulated by a regulator 6, serving as a speed reference, a processing electrode 1 is fed in the direction of a workpiece 2 according to a processing progress with the aid of an electric motor 7. In which case, a voltage proportioning a current flowing through a gap between the electrodes 1 and 2 is generated at both ends of a shunt 9, and voltage signals therefrom are converted into a frequency pulse through a V-F converter 11 for counting. A ratio between a preceding and a present value per a unit time by means of a signal from a control device 18, is determined through the working or resistors 13a, 13b, D/A 14a, 14b, and a divider 15. An output therefrom is compared with reference values REF 1 and REF 2 responding to a ratio of 1.1 or 0.9, when the output exceeds 1.1, an electrode feed speed is decreased by means of a comparator 16a and a drive device 24a, and when below 0.9, the speed is increased. This constitution holds a gap between processing electrodes at a proper value, and prevents the occurrence of shortcircuit.

Title: Piping joint method for expansion pipe
Inventor: NASU TAKU
IPC: F16L1/024
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a piping joint method for expansion pipes that sufficiently absorbs, by way of deformation, the tensile load that acts on piping upon ground displacement owing to liquefaction or the like at an earthquake, with the aid of a simple means. SOLUTION: A pipe body 1c is laid through a wall 6a into a structure 6 under fixation by the wall 6a. An expansion pipe 11b having an axially expandable corrugated expansion portion 12b is deformed or axially compressively loaded from its original shape to have a corrugation pitch (n) smaller than that (m) of the original expansion pipe. The expansion pipe 11b is welded at its one end to the pipe body 1c and at the other to another pipe body 1d buried in the ground 9. An axial tensile load acting on the piping promotes its axial deformation, which sufficiently absorbs the tensile load, together with an increased elongation change from the load application to the next application of a further increased load when corrugations 13b in the corrugated expansion portion 12b fully elongate.

Filed: 1988-07-11
Abstract: PURPOSE:To enable even a unit of original image pattern formed at an end or corner of a original pattern plate to be exposed independently onto a wafer by providing means for freely moving masking plates or dousers relative to the optical axis while designing the masking plates in such a manner that they can select any desired unit of image pattern on the original pattern plate and make the selected unit of image pattern to be exposed onto the surface of the wafer. CONSTITUTION:One end of dousers 32-35 are supported by sliding elements 36a, 36b, 37a and 37b, respectively while the other ends thereof are supported slidably by sliding plates 53, 54 provided on a plate 31. The plate 31 is arranged on an exposure apparatus in such a manner that optical axis of light source is coincident with the central point Q of an aperture 31a. Different patterns are drawn in circuit patterns 5a-5i on a reticle 5, respectively. If the circuit pattern 5g located at the corner is to be exposed, for example, all the patterns other than the pattern 5g can be shielded from light since each of the dousers 32-35 can cover by itself a region extending over the central point Q from one edge of the aperture, namely about 4/5 of the area of the aperture. Accordingly, the circuit pattern 5g alone can be exposed onto the wafer.

Abstract: PROBLEM TO BE SOLVED: To draw an FPC bridged between a lens holder and a holder support member in an objective lens driver of an optical pickup device around so as to become advantageous from view points of a reduction in a thickness of the device, the degree of freedoms of designing the holder or the like. SOLUTION: In the objective lens driver 1 of the optical pickup device, FPCs 7, 8 of a symmetrical state are disposed to a virtual axis L2 passing centers of a slide shaft 3 and the lens between the holder 4 and a holder support member 2. These FPCs 7, 8 are disposed in a space between an outer periphery of the holder 4 and an inner periphery of the sidewall of the member 2, and drawn around in the state bent to surround the virtual axis extended substantially parallel to the shaft 3. A reduction in the thickness of the device can be realized as compared with the case that the FPCs 7, 8 are drawn around above and below the holder. Since it is not necessary to form a through hole for drawing around the FPCs at the holder 4, the degrees of the freedoms of designing the holder and laying out placing components are increased.
