The present invention provides a die bonder capable of stripping a die without fail, or a highly reliable die bonder or pick-up method using the die bonder. When a die to be stripped out of plural dies (semiconductor chips) bonded to a dicing film is to be tossed and stripped from the dicing film, the dicing film corresponding to predetermined positions out of the peripheral portion of the die is tossed to form stripping start points and then, the dicing film corresponding to portions other than the above predetermined positions is tossed to strip the die from the dicing film.

An optical fiber ribbon includes a plurality of optical fibers encapsulated within a matrix material, where the optical fiber coating(s) and the matrix material(s), and optionally any ink layers thereon, are characterized by compatible chemical and / or physical properties, whereby the fiber coating and matrix and any ink layers therebetween can be reliably stripped from the optical fibers to afford a suitable strip cleanliness. Novel ink formulations that can be used in the making of such fiber optic ribbons, methods of making such ribbons, and their use are also described.

Provided is a water-resistant sound transmitting member that is reliably released from a release paper when a protruding section of a tab is pulled. A production method for this water-resistant sound transmitting member (2) includes: a step in which a first layer (71), a preliminary film body (61), a second layer (72), and a preliminary tab body (63) are laminated in said order and a laminate (52a) is prepared; a step in which a blade (90) is inserted from the first layer (71) in the laminate (52a) towards the preliminary tab body (63), the first layer (71), the preliminary film body (61), and the second layer (72) are cut and a first adhesive layer (21), a water-resistant sound transmitting film (11), and a second adhesive layer (22) are formed, and a notch (13n) that connects to the end surfaces of first adhesive layer (21), the water-resistant sound transmitting film (11), and the second adhesive layer (22) is disposed in a surface on the second layer (72) side of the preliminary tab body (63); and a step in which the preliminary tab body (63) is cut and the tab (13) is formed.

The invention discloses a negative plate delaminating device, comprising a rack and a delaminating component. The delaminating component is arranged on the rack and comprises clamping mechanisms, a plate-releasing mechanism, a bottom-locating mechanism, a plate-loosening mechanism and a plate-receiving mechanism, wherein the clamping mechanisms are mutually arranged above the rack at interval in the longitudinal direction; the plate-releasing mechanism is used for delaminating deposition metal plates from the two sides of the negative plate; the bottom-locating mechanism is used for locating the bottom end of the negative plate; the plate-loosening mechanism is arranged at the two transverse sides of the rack and comprises a push rod which moves along the transverse direction and arrangedon the rack for thrusting the negative plate; and the plate-receiving mechanism comprises at least one plate-receiving platform which can vertically move and is used for bearing the deposition metal plates. According to the negative plate delaminating device in the embodiment of the invention, the plate-receiving mechanism is arranged below the delaminating component to bear the delaminated deposition metal plates, thus the work noise and the device damage caused by impact of the device below are both avoided; and the deposition metal plate can not be scratched during the process of sliding, thus the appearance and the quality are reliable.

A wedge-shaped jig (6) is inserted into a gap between a first substrate (21) and a second substrate (22) at a corner (221) of the second substrate (22) and separation of the attached first substrate (21) and second substrate (22) starts to proceed; then, a second suction pad (53) of a second suction portion (51), which is the closest to the corner (221), moves upward. Then, first suction pads (43) of first suction portions (41a), (41b), and (41c) sequentially move upward such that one side of the second substrate (22) separates from the stacked body. Although the second substrate (22) warps as the separation of the second substrate (22) proceeds, each of the plurality of first suction pads (43) elastically deforms. Therefore, the first suction pads (43) can be prevented from being detached from the second substrate (22), and the substrate (22) can be securely separated from the stacked body.

The bolt of the present invention can reliably peel coating even when fastened with a low torque, and can secure sufficient conductivity. A coating peeling part for peeling coating is formed at a tip end of an axis part in which a regular screw part is formed. The coating peeling part includes crushing parts having a trapezoidal top part and having a flank which is projected at a different angle with respect to the flank of the regular screw part; and a protruding part which is arranged adjacent to the crushing parts and whose top part projects beyond the outer diameter of the regular screw part.

Disclosed is a method of suction of an object to be worked (15) upon a suction unit (14) and a method of manufacturing a ceramic capacitor, which employ a plastic sheet (11) being air permeable in the thickness dimension thereof as a suction sheet, having improved air permeability while maintaining a small diameter for the pores (aperture diameters) that are the air permeable paths for ensuring the air-permeability. The plastic sheet (11) is a non-porous sheet whereupon two or more through holes are formed that pass therethrough in the thickness direction. The through holes are straight holes that pass through the plastic sheet in direct lines. The diameter of the through hole is less than or equal to 20[mu]m. The air-permeability of the plastic sheet in the thickness direction is less than or equal to 10seconds / 100mL, a Gurley number measured in accordance with JIS P8117. Under the methods disclosed herein, the plastic sheet (11) is positioned upon the suction face of the suction unit (14).

PROBLEM TO BE SOLVED: To provide a rotary valve capable of enhancing the certainty of the adhesion prevention of raw materials.SOLUTION: A rotary valve 1 transporting raw materials to an input port of a pressurizing and steaming device includes: a supply port 5 for the raw materials; a discharge port 6 for the raw materials; a casing 4 in which an inner peripheral surface 11 is formed between the supply port 5 and the discharge port 6; a rotor 3 forming a plurality of pockets 10 in the casing 4 and rotated in the casing 4; and a steam supply port 15 for injecting steam into the pockets 10. The steam supply port 15 is formed at the inner peripheral surface of the casing 4 at a side where the rotor 3 is returned from the discharge port 6 to the supply port 5 and formed in a position where the steam is injected into the pockets 10 opened to the discharge port 6.
