Abstract: A vacuum pad includes a support member that includes a vacuum passage and a bellows that is attached to the support member, and the cover body includes a cylindrical body portion, an attaching portion projecting from one end of the body portion, and a flange portion projecting radially outward from another end of the body portion. The cover body covers the outside of the bellows when the bellows contracts and holds a workpiece by suction.

Abstract: A suction board includes a nonwoven fabric sheet that has a uniform thickness and is formed into a disk shape, and a ring-shaped holding body that movably supports the nonwoven fabric sheet to an attaching adapter. The suction surface is formed by the flat surface of the nonwoven fabric sheet, and the nonwoven fabric sheet is provided with an air-impermeable region in the outer peripheral portion and an air-permeable region excluding the outer peripheral portion, and the density of the air-impermeable region is higher than the density of the air-permeable region.

Abstract: A pad of a pad-equipped lift device has a connecting portion that is attached to an end of a body and a flexible skirt portion that expands toward the distal end of the skirt portion, and the distal end of the skirt portion is deformed so as to shrink inward when air flowing along an end surface of the body flows on the inner side of the skirt portion.

Abstract: A lift device includes a body having a cylindrical shape and an elastic member having an annular shape. The body includes, at an axial end thereof, a flat surface configured to hold a workpiece. The elastic member is disposed on an outer periphery of the flat surface of the body, and includes an annular protruding portion that protrudes beyond the flat surface of the body in an axial direction of the body. The annular protruding portion has a circular-arc-shaped cross-section. Air supplied to the body flows along the flat surface of the body and the annular protruding portion of the elastic member.

Abstract: A non-contact transport device includes a deflector having a flange portion provided with a plurality of nozzle grooves extending radially outward and arranged equidistantly in the circumferential direction. The nozzle grooves are each formed to be hollowed with respect to an upper surface of the flange portion so as to have an arc-shaped cross section, and constitute lead-out channels together with a flat surface of a hollow of a body. A pressure fluid is supplied through a first port of the body into the body and flows through the plurality of nozzle grooves to a workpiece holding surface along first and second curved surfaces of the hollow. As a result, the pressure fluid flowing at high speed between the workpiece holding surface and a workpiece generates a suction force exerted toward the body side, whereby the workpiece is suctioned.

Abstract: A vacuum pad suctions a workpiece by utilizing a vacuum pressure, and includes a support member having a vacuum passage inside, a bellows secured to the support member, and a restriction member attached to an inner side of the bellows. When the bellows is contracted, the restriction member comes into the vacuum passage.

Abstract: A suction device includes an adapter having in the interior thereof a supply passage to which a negative pressure fluid is supplied, a bellows connected to a distal end of the adapter, and a pad member disposed at a distal end of the bellows and to which a workpiece is attracted under suction. In addition, the suction device attracts the workpiece under suction by a negative pressure fluid which is supplied to the pad member through the supply passage and the bellows. An attachment which is capable of being tilted with respect to the axis of the bellows is provided in the interior of the bellows. In the attachment, a main body portion thereof is disposed in facing relation to a suction surface of a skirt, and a shaft portion is inserted into the supply passage at a time that the workpiece is attracted under suction.

Abstract: A suction device includes an adapter having a supply passage to which a negative pressure fluid is supplied, a bellows connected to a lower end of the adapter, and a pad member formed at the distal end of the bellows. The pad member has plural first and second ribs on a suction surface that attracts a workpiece under suction. The first ribs are disposed on an outer circumferential side of an attachment provided in the center of the pad member and extend toward the outer circumferential side. The second ribs are provided on an outer circumferential side of the first ribs, and are disposed in a circumferentially offset manner with respect to the first ribs. Additionally, between the respective first ribs which are disposed alongside one another in the circumferential direction of a skirt, supply paths are formed to which the negative pressure fluid is supplied from the attachment.

Abstract: The present invention aims to provide an external-electrode discharge lamp able to suppress luminance variation, a manufacturing method for the lamp, and a backlight unit. A lamp (10) of the present invention includes a glass tube (11) sealed at both ends, and electrodes (18) and (19) provided around outer circumferential peripheries of the ends in the axial direction of the glass tube (11). During operation of the lamp (10), the electrodes (18) and (19) and the glass tube (11) between the electrodes (18) and (19) and a discharge space (14) equivalently function as first and second capacitors, whose capacitances are substantially the same.

Abstract: Pressed shape steel, made of a low cost general steel material that is not hardened, forms a frame with long grooves cut therein. Guide rails, made of a specialized steel material that can be subjected to a hardening treatment, are hardened. Thereafter, outer surfaces of the hardened guide rails are ground and the guide rails are integrally joined in the long grooves. Ball-rolling grooves are formed in the guide rails, thereby completing a guide-equipped frame for an actuator. Because the general steel material and the specialized steel material are principally ferrous materials, both exhibiting a Young's modulus at or above 170 GPa with substantially the same coefficient of linear thermal expansion, the frame needn't be increased in size or have a complex internal structure to reinforce the strength of the frame, and the guide rails remain securely retained in the grooves even if the actuator experiences changes in temperature.
