Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a front-to-backside conduction board which has a high conductivity of conducting parts, a high air sealability, a high position accuracy, a superior smoothness, a superior flatness, and a wide variety of materials usable as an insulator, and allows the manufacturing labor and cost to be reduced, and a method of manufacturing a semiconductor mounting board using the front-to-backside conduction board made by that method. SOLUTION: Liner conductors are pressure-fitted at their top ends into an insulator being in a softened state in their lengthwise direction, and the insulator with the pressure-fitted conductors is hardened to manufacture a front-to- backside conduction board containing the linear conductors in the plate-like insulator, thus making the front side of the insulator conductive to its backside through the conductors. Semiconductor elements are bonded to the front-to- backside conduction board manufactured by such method, thereby manufacturing a semiconductor mounting board.

Respective pairs of the movable partitions are holizontally slidably arranged along the direction of the thickness of the glass sheet G and facing each other on opposite sides of the glass sheet G. The distance between the movable partitions in each pair can be adjusted so that their distances from the glass sheet G can be minimized.

Abstract: PROBLEM TO BE SOLVED: To form a semiprocessed glass product effectively suppressing generation of shrink at the glass surface after pressed and hence having a reduced margin for scraping in the direct press-forming method. SOLUTION: The upper surface of a glass gob on the forming surface of a lower die is cooled and the temperature inside the glass gob is brought close to that of the periphery of the glass gob by suppression of heat radiation from the glass gob. Thereafter, the fused glass fed to the forming surface of the lower die is pressed. The pressing of the glass gob is carried out with viscosity of 3.5-10.65 poise. Since the upper surface of the glass is quenched before the pressing of the glass, heat of the glass is rapidly removed and the temperature difference between the inside and outside of the glass is made closer and thus the glass can be pressed with a relatively high and uniform viscosity. Hence, heat contracting amount of the glass can be reduced and the difference of heat contracting amount between the inside and outside of the glass can also be reduced. Accordingly, generation of shrink on the surface of the glass is decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a process for producing glass panes which is capable of making the warpage of the glass panes smaller and an apparatus for production therefor. SOLUTION: This process consists in producing the glass pane by allowing fused glass 3 to flow down, forming the glass to a planar form by a forming body 2 and drawing the formed planar glass 3' downward while holding the glass by a pair of pulling rollers. Plural sets of a pair of the pulling rollers are arranged in the progressing direction of the glass in this process. The circumferential speed of a pair of the pulling rollers arranged above is set higher than the circumferential speed of a pair of the pulling rollers 6' arranged below.

Abstract: PROBLEM TO BE SOLVED: To provide a process for producing glass panes capable of lessening the shrinkage in the transverse direction of the glass panes after parting from a forming body and greatly improving the warpage of the glass panes. SOLUTION: This process consists in producing the glass pane by allowing fused glass 3 to flow down, forming the glass to a planar form by the forming body 2 and drawing the formed planar glass 3' downward while holding the glass by pulling rollers 6. Cooling rollers 7 for holding both ends of the glass pane 3' are disposed below the forming mold 2 in this process. In addition, the circumferential speed of these cooling rollers 7 is set smaller than the circumferential speed of the pulling rollers 6.

Abstract: PROBLEM TO BE SOLVED: To obtain a efficient filtration action and to effectively fulfill filter purification function utilizing a photocatalytic reaction by forming a filter device of filter material so that one end part in the longitudinal direction is opened and other end part is closed and also size of an opening is formed gradually smaller as nearer approaching the other end part. SOLUTION: An opening part 20 used for the inflow port of material to be filtrated is formed of many long fibrous bodies 11 in one end of the filter device. A bundled convergent part 21 is formed in other end thereof. A part surrounding space part 22 formed in a range from the opening part 20 to the convergent part 21 constitutes a filtration part 23 being a part performing filtration action. Filtration area of the filtration part 23 is made large by this constitution. Further, when space part being the flow path of fluid to be filtrated is formed into a shape which is gradually narrowed as nearer approaching the inner part (tip part), pressure decrease of introduced fluid is supplemented in some degree and pressure difference between respective positions on the inner peripheral face of the filtration part 23 is made small. Therefore, such action effect is obtained that deviation of collection is relaxed.
