Abstract: A method for manufacturing a semiconductor device includes: providing a wafer-bonding stack structure having a sidewall layer and an exposed first component layer; forming a photoresist layer on the first component layer; performing an edge trimming process to at least remove the sidewall layer; and removing the photoresist layer. In this way, contaminant particles generated from the blade during the edge trimming process may fall on the photoresist layer but not fall on the first component layer, so as to protect the first component layer from being contaminated.

Abstract: A grip device for a pole includes a grip and a wrist strap unit. The grip has a connecting part that defines a connecting space therein, and that has a lower portion and a protruding portion disposed in the connecting space. The wrist strap unit includes a connecting member that engages removably the connecting space, and that has a tail part. The tail part is pivotable between a locked position, where the tail part is adjacent to the lower portion so that the connecting member is retained in the connecting space by the protruding portion, and an unlocked position, where the tail part is away from the lower portion and the protruding portion so that the connecting member is permitted to be separated from the connecting part.

Abstract: A telescopic tube assembly includes a telescopic tube subassembly having a first tube and a second tube, a tubular member, a sleeve member, at least one retaining member, an actuating sleeve, and a biasing member for biasing the actuating sleeve to a locked position. When the actuating sleeve is in the locked position, the retaining member is engaged in a cavity of the tubular member to guard against axial movement of the second tube relative to the first tube. When the actuating sleeve is moved to an unlocked position against a biasing force of the basing member, the retaining member is disengaged from the cavity to permit the axial movement of the second tube.

Abstract: An adjustable and retractable rod includes an external pipe fitting, a multi-section rod and a positioning unit. The multi-section rod includes a first and at least one second foldable rod, where the first and second foldable rods have the same outer diameter, and the positioning unit includes a linkage rope, a positioning component and a locking component, which are used to pull the external pipe fitting and the first foldable rod relative to each other. The linkage rope can be dragged, and the locking component and the positioning unit interlocked or separated. When the locking component and the positioning component are interlocked, the external pipe fitting can be connected to the multi-section rod unit in an unfolded state. When the locking component moves away from the positioning component, the first and second foldable rods of the multi-section rod are folded and in parallel relative to the external pipe fitting.

In response to pressing of the actuating end region, the latch block is displaced from a locked position, where the blocking end region is in blocking engagement with a shoulder surface of the inner tubular member, to an unlocked position.

Abstract: A telescopic tube assembly includes a telescopic tube subassembly having first and second tubes, a tubular member configured to move with the second tube, an outer sleeve sleeved on the first tube, a retaining member, an actuating member, and a biasing member. When the second tube is in an extended position, the second tube extends out of the first tube, and the retaining member is engaged in a cavity of the tubular member so as to guard against axial movement of the second tube. When the second tube is in a retracted position, the second tube is received in the first tube, and the retaining member is retracted to be disengaged from the cavity so as to permit the axial movement of the second tube.

Abstract: A telescopic rod includes a large-diameter rod segment, a small-diameter rod segment, and a clamping unit. The large-diameter rod segment is telescopically joinable to the small-diameter rod segment, and includes a uniform-dimension main region, a marginal region, and a dimension reducible region which has left and right grip areas defined by an elongated gap and proximate and distal transverse slots communicated with the elongated gap. The clamping unit is displaceable between an untightened state and a tightened state, where the dimension reducible region is squeezed by the clamping unit such that the left and right grip areas tightly and evenly grip the small-diameter rod segment.

Abstract: A collapsible tubular rod includes a tubular rod body which has first and second rod segments and which is convertible between collapsed and assembled states, a socket body fixed in the first rod segment, a plug member configured to be brought into rotatable engagement with the socket body, a guiding sleeve sleeved on the plug member, and a spring-loaded pin received in the plug member so as to extend outwardly of the guiding sleeve, and a connecting cord. When the tubular rod body is in the assembled state, the plug member and the guiding sleeve are guided by the socket body to permit the spring-loaded pin to extend outwardly of an outer surface of the first rod segment.

Abstract: A clamping device includes a flexible sleeve secured to one segment of a telescopic rod and having a collar for receiving the other segment, and two lugs displaceable between untightened and tightened positions, and an elastic lining member disposed on the collar such that, as a result of displacement of the lugs from the untightened position to the tightened position, the elastic lining member is strained to acquire a biasing force that biases the lugs back toward the untightened position, thereby facilitating telescopic movement of the telescopic rod during length-adjustment.

A releasably clamping member has a radially expandable tubular plug mating with and axially movable relative to the inner friction surface so as to be displaced from a normal position for gripping the connecting cord to an expanded position for tension adjustment of the cord when an actuator is actuated manually to move axially or radially.

Abstract: A positioning sleeve includes first and second surrounding portions adapted to surround outer and inner tube sections of a telescopic rod, respectively. The second surrounding portion has a plurality of angularly spaced-apart recessed parts and a plurality of compressible retaining units respectively disposed in the recessed parts. Each retaining unit is connected to the corresponding recessed part, and has an engaging part projecting toward a through hole in the second surrounding portion, and a deformable space defined between the engaging part and the respective recessed part. The deformable space is deformed when the inner tube section is friction-fitted into the second surrounding portion and when the engaging part of each retaining unit abuts the inner tube section.
