A method for performing a liftoff operation involves printing a liftoff pattern using low-resolution patterning techniques to form fine feature patterns. The resulting feature size is defined by the spacing between printed patterns rather than the printed pattern size. By controlling the cross-sectional profile of the printed liftoff pattern, mask structures may be formed from the liftoff operation having beneficial etch-mask aperture profiles. For example, a multi-layer printed liftoff pattern can be used to create converging aperture profiles in a patterned layer. The patterned layer can then be used as an etch mask, where the converging aperture profiles result in desirable diverging etched features.

A sheet processing apparatus according to the invention includes a conveying portion that conveys a sheet; and an abutment member against which an end of the sheet in a conveying direction abuts, the sheet being conveyed by the conveying portion. Herein, the abutment member is movable so as to change a distance between the abutment member and the conveying portion adjacent to the abutment member based on sheet information about the stiffness of a sheet, when an end of the sheet in the conveying direction is abutted against the abutment member.

A method of optimizing the timing between signals to be latched and a respective latching clock signal is suggested wherein test timings are provided according to which a delay test value of a clock delay line (CDL) are generated. According to the delay test values a clock signal (C) and a sample signal (S) are received through said clock delay line (CDL) and through said sample signal line (SSL), respectively. Respective phase differences for the distinct delay test values are obtained. A delay value is chosen and set for operation for which the respective obtained phase difference fits best to given target timing data.

A sealing structure which seals a container body and an aerosol valve without providing a seal member between them. An aerosol container employing the seal structure comprises a bottomed cylinder like container body and an aerosol valve firmly fixed to the opening of the container body. The seal structure between the container body of the aerosol container and the aerosol valve is formed of a valve support portion of the container body and a step portion of the aerosol valve. The aerosol container is manufactured by deforming a corner of the step portion into a curved surface shape from a square shape by applying an annular force to the step portion from a convex surface by plastically deforming a lower part of a cover cap and a part of the container body while pushing the cover cap downward.

A leadframe (100) for electronic systems comprising a first sub-leadframe (110) connected by links (150) to a second sub-leadframe (120), the first and second sub-leadframe connected by tiebars (111, 121) to a frame (130); and each link having a neck (151) suitable for bending the link, the necks arrayed in a line (170) operable as the axis for bending the second sub-leadframe towards the first sub-leadframe with the necks operable as rotation pivots.

The invention discloses a track-type movable light steel keel, which comprises a main keel, an auxiliary keel and a suspension rod. The main keel is divided into an upper keel and a lower keel. The keel is connected in a crisscross manner, and the relative position of the lower keel and the upper keel can be adjusted by sliding to achieve the purpose of adjusting the horizontal position of the lower keel; Effective length of the rod. The advantages of this track-type movable light steel keel are: because the upper keel and the lower keel adopt a sliding fit structure, and the effective length of the boom can be adjusted by the horizontal adjustment code, not only can the horizontal position of the lower keel be adjusted laterally by sliding, but also The vertical height of the main keel can be adjusted longitudinally, so that the installation position of the ceiling or wall can be adjusted flexibly; it not only saves the construction time on site, improves the work efficiency, but also has a better overall effect of the ceiling.

The invention relates to the technical field of stainless steel pipe fittings, in particular to a ring clamp type anti-freezing stainless steel pipe fitting, including a connector and a connecting pipe. The connector includes a limit ring, a No. 1 inner snap ring, a No. 2 inner snap ring and an outer snap ring. The connecting pipe includes a flow end, an outlet end and a connecting end. The number of outlet ends is 2, and the connecting end is welded to the connecting head; the second internal snap ring provides a buffer space for the connecting pipe inserted into the connecting head, which reduces the difficulty of inserting the connecting pipe and is easy to weld; The No. 1 inner snap ring and the No. 2 inner snap ring provide a buffer space for the connector to shrink inward, and the outer snap ring provides a buffer space for the connecting pipe to expand outward, so as to prevent the connector and the connecting pipe from freezing off; the connecting pipe and the connecting pipe of the present invention The connection effect and sealing between the connectors are more stable and reliable, and the connecting pipe is easier to enter the connectors, which reduces the difficulty of welding and prevents the connectors from freezing off.

The present invention discloses one kind of heating screw for plastic processing machine and its making process. The heating screw includes one screw, at least two sections of porous refractory bricksin one line inside the screw, and one heating element set inside the long through hole in the porous refractory bricks. The heating screw has the advantages of simple structure, easy installation, etc. It is applied in plastic pelletizing machine, plastic injection molding machine, blow molder, plastic extruding machine and other plastic processing machines.

The invention relates to the technical field of connector equipment, and provides an absorption connector. The absorption connector comprises a male seat and a female seat which are connected with each other, wherein magnets which are attracted to each other are respectively arranged on a connecting surface of the male seat and a connecting surface of the female seat; the periphery of the female seat is circumferentially extended to form a peripheral wall; the male seat is sleeved in the peripheral wall. The male seat and the female seat are adopted in the absorption connector; the periphery of the female seat is circumferentially extended to form the peripheral wall, so that the male seat can be firstly sleeved in the peripheral wall; then the magnet on the connecting surface of the male seat is attracted to the magnet on the connecting surface of the female seat, so that the male seat and the female seat can be steadily connected with each other. Therefore, compared with the conventional connector, the connector has the advantages that through the limiting on the male seat by the peripheral wall of the female seat, and the mutual absorption of the two magnets, the male seat can be steadily connected with the female seat, which avoids the problems of difficult alignment, inconvenient insertion / removal and loose connection of the male seat and the female seat.
