Inventor: SEKIDO KEIJI
IPC: H05K3/46
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To provide the method of manufacturing an insulating sheet having through-holes, which does not require an exclusive attracting plate for each through-hole pattern, even if the hole patterns of the through-holes which are formed in the insulating sheet (for instance a green sheet) vertically and have conductive layers on their inner circumferential surfaces are different, and does not require the replacement of the attracting plate. SOLUTION: An insulating sheet attracting plate 30, which has attracting holes 31 over the whole surface regardless of the pattern of a through-hole formed in a green sheet, is used. A porous sheet member 20 such as a paper sheet, etc., is placed on the attracting plate 30. An insulating sheet 1 is placed on the attracting plate 30 with the porous sheet member 20 therebetween. The inner circumferential surface of a through-hole 2 is coated (for instance screen printed) with conductive ink 8 by vacuum attraction. Although the ink 8 is sucked through the paper sheet 20 due to the porosity of the paper sheet 20, the flow of the ink 8 is blocked by the fiber parts of the paper sheet 20 and will not spread unnecessarily. Not only the paper sheet but also a cloth sheet or unwoven fabric cloth sheet may be used as a porous sheet.

Title: Loading direction control device for roll paper
Inventor: OBATA TAKIO
IPC: B65H43/04
Filed: 1993-10-20
Abstract: PURPOSE:To surely judge the adequacy of the loading direction of the roll paper and prevent erroneous loading by rotating the roll paper in the direction opposite to the paper feed side when the roll paper is loaded at a roll paper replenishment section, and detecting the unwinding direction of the tip of the roll paper with a roll paper unwinding direction detecting means. CONSTITUTION:When the replenished roll paper R1 is loaded to a roll paper replenishment section 13, a CPU drives a reverse drive motor M1 to reversely rotate the replenished roll paper R1 for a fixed time. When no tip swelling is generated on the reversed replenished roll paper R1 and detected by a roll paper tip detecting sensor S1 for a fixed time, the replenished roll paper R1 is judged to be in the proper loaded state, and the reverse drive motor M1 is stopped driving. If the roll paper tip detecting sensor S1 detects the tip swelling of the roll paper R1 when the replenished roll paper R1 is reversely rotated, the replenished roll paper R1 is judged to be erroneously loaded in the inadequate reverse unwinding direction, and an annunciator is operated to report it to a person in charge.

Title: Ion implantation device
Inventor: YASUDO TAMAKI
IPC: H01L21/265
Filed: 1990-10-23
Abstract: PURPOSE:To prevent local charge-up on a target by narrowing an arc chamber slit more at its central part than at both its ends and uniforming an ion density distribution CONSTITUTION:An arc chamber slit 3 is installed which is narrower at its central part than at both its ends. Plasma generates inside an arc chamber 1 and the plasma density is higher the more it goes toward the central part but lower the more it goes towarad the peripheral part. Positive ions thus pass the slit 3, which narrows only at the central part of high ion density to allow the same amount of the positive ions to pass through the central part as through the peripheral part. A drawn ion beam section 6 has an ion density distribution 7 uniform in the ion beam section. This eliminates local charge-up on a target.
