Abstract: A printing operation is repeatedly performed with respect to one substrate 2, the printing operation including the step of loading the substrate 2 (the step ST1), then contacting an upper surface of the substrate 2 with a mask 13 (the step ST4), reciprocating a squeegeeing operation to slide squeegees 33b on the mask 13 in contact with the substrate 2 to transfer a paste Pt on the mask 13 to the substrate 2 (the step ST7 and the step ST8), separating the substrate 2 from the mask 13 for a snap off (the step ST9), and while unloading the substrate 2 (the step ST11), performing mask cleaning to remove the paste Pt that is adhered to a lower surface of the mask 13 (the step ST12).

Abstract: To improve the freedom in material selection of cutter while suppressing increase in loads on the operator, a sliced specimen preparing apparatus of the present invention includes a cutter storage section storing a plurality of cutters, a specimen block cutting unit holding a cutter and slicing a surface layer of a specimen block, and a cutter transfer unit transferring a cutter stored in the cutter storage section to the specimen block cutting unit and replacing the cutter held by the specimen block cutting unit, the specimen block cutting unit is movable between a sliceable position where a blade edge of the cutter is oriented obliquely downward and a replacement position where the blade edge of the cutter is horizontally or oriented obliquely upward, and the cutter transfer unit replaces the cutter held by the specimen block cutting unit when the specimen block cutting unit is located at the replacement position.

Abstract: Provided are a screen printer and a screen printing method capable of reducing poor printing by realizing smooth rolling of a paste. When a squeegee 32 is slid on a mask 5 so as to transfer a paste Ps to a substrate 2, leakage prevention members 33 are slid on the mask 5 along with the squeegee 32 so as to prevent the paste Ps on the mask 5 from leaking out of both sides of the squeegee 32. The height H0 of the paste Ps on the mask 5 is greater than the height Hm of the leakage prevention members 33 from the upper surface of the mask 5, and the paste Ps located at a position greater than the height Hm of the leakage prevention members 33 is rolled.

Imaging light is taken in the camera in a state that the upper illuminating part and the lower illuminating part are individually operated in a mask imaging step and a board imaging step, respectively.

Abstract: At the two ends of a pair of clamping members (9a) which sandwich and clamp a board (10) from the Y direction, mask supporting members (9b) forming a rectangle frame are disposed, and a screen mask (12) is supported from below by the mask supporting members (9b) in a state that the board (10) abuts against the under surface of the screen mask (12). A downwards bending of the screen mask (12) can be prevented, and the time and labor of maintenance can be decreased by preventing the deposits of paste on the screen mask (12) that occur due to the bending.

Abstract: A pressing mechanism that presses a dam member 30 against a screen mask 12 has a guide shaft 32 that guides a direction of movement of the dam member 30 during pressing operation and a compression spring 33 that forces the dam member 30 in an axial direction of the guide shaft 32. A printing pressure value at which the dam member 30 is pressed against the screen mask 12 is made stable, to thus make stable an effect of preventing effluence of the paste to the outside of a print width on the screen mask 12.

Abstract: There is provided a capacitor that has excellent transient response characteristics, can be used as a distributed constant type noise filter, and can be used as a composite component having two functions of a capacitor and a distributed constant type noise filter through further reduction of an ESL of a solid electrolytic capacitor with a solid electrolytic capacitor of which capacitance is easily increased. There are prepared two capacitor element pieces 121 where both ends of an anode body of each of the capacitor element pieces form anode lead-out portions 122 and 122 and both surfaces of a middle portion of the anode body form cathode lead-out portions 123. The two capacitor element pieces 121 and 121 are stacked so that the cathode lead-out portions 123 and 123 overlap with each other and the anode lead-out portions 122 and 122 are substantially orthogonal to each other. Accordingly, a capacitor element 120 is formed.

Abstract: Sliced specimens can be automatically and continuously prepared and burdens of an operator can be reduced while accuracy required for the sliced specimen is maintained. The sliced specimen is prepared by relatively moving a specimen block transfer section and a cutter, and when a slicing operation to adjust the height position of the specimen block is continuously performed so that the cutting surface of the specimen block is located at a sliceable position, the cutter is moved so that a contacting area of a blade edge of the cutter that firstly contacts the specimen block after the height position adjustment is sequentially changed, every time previously set number of times of slicing operation is completed. Thereafter, the height position of the blade edge of the cutter after the change is measured by a detector, and based on the measurement information of the detector, the sliceable position is corrected and the slicing operation is resumed.
