Abstract: A pneumatic tool with a forward and reverse rotation structure includes a housing, a retaining member, two push buttons and a positioning pin. The housing includes an installation space. The retaining member is arranged inside the installation space to divide it into two push button accommodating cavities. The two push buttons movably slide inside the two push button accommodating cavities. The retaining member restricts the sliding ranges of the two push buttons. The positioning pin penetrates into the housing to allow the retaining member to be secured by the housing and the positioning pin. Accordingly, the retaining member is secured firmly while allowing it be removed for replacement and repair, the positioning pin is prevented from slippage, and any slipping off or snapping off of components between the sliding block of the push button and the slot wall of the retaining member can also be prevented.

Abstract: A semiconductor device includes a substrate and a light collimator layer. The substrate has a plurality of pixels. The light collimator layer is disposed on the substrate. The light collimator layer includes a light shielding layer disposed on the substrate, a plurality of transparent pillars disposed in the light shielding layer, and a plurality of optical microlenses disposed on the pixels.

Abstract: A method for forming a semiconductor device is provided. The method includes providing a substrate having a scribe line, forming a sensing pixel array in the substrate, forming a plurality of transparent pillars over the substrate, and forming a light shielding layer over the substrate and the transparent pillars. The sensing pixel array has a plurality of sensing pixels, and each of the transparent pillars is correspondingly disposed on one of the sensing pixels of the sensing pixel array. The method further includes performing a first cutting process to form an opening directly above the scribe line, while leaving the remaining material covering the scribe line, and performing an etching process along the opening to remove the remaining material until the scribe line is exposed.

Abstract: A pneumatic tool including a gun body, a rotating valve, a valve bushing and a trigger set is provided. The rotating valve is disposed at the gun body and includes at least one opening. The valve bushing sleeves the rotating valve and includes two ports. The trigger set is operably disposed at the gun body and is operably coupled to the rotating valve. A rotation of the trigger set causes the rotating valve to rotate to a first position relative to the valve bushing such that the at least one opening of the rotating valve is aligned to one of the two ports, and the rotation of the trigger set causes the rotating valve to rotate to a second position relative to the valve bushing such that the at least one opening of the rotating valve is aligned to the other one of the two ports.

Abstract: An pneumatic tool includes a front section, a rear section connected to and disposed behind the front section, a driving unit, and an air cylinder unit. The rear section includes a main body, a handle connected to the main body and adjacent to the front section, and an intake passage in fluid communication with the outside. The air cylinder unit includes a first cylinder mounted within the rear section, a second cylinder connected to the first cylinder, an extension portion extending into the handle, and an inclined intake channel having an inlet in fluid communication with intake passage, and an outlet in fluid communication with the first cylinder. The rotor unit is mounted rotatably within the first and second cylinders for activating the driving unit.

Abstract: A collapsible keyboard includes a keyboard base, at least one section hinge, a key base, at least one fixed hinge, at least one movable hinge and a plurality of keys. The keyboard base has a plurality of first sections. The section hinge connects the plurality of first sections so that the first sections are rotatable with respect to each other. The key base has a plurality of second sections provided on the first sections. The fixed hinge connects the second sections so that they are rotatable with respect to each other. The movable hinge connects one of the first sections and one of the second sections. The keys are provided on the second sections.

Abstract: A holding apparatus engages with an information input device, particularly a foldable keyboard, for supporting portable electronic devices such as pocket PC, Palm PC, PDA, mobile phone and the like. The holding apparatus includes a receiving dock which has connector spindles pivotally engaged with the input device and a slot. A bracket is provided to slide in the slot at a first position to flatly fold on the input device to facilitate carrying when not in use. The bracket may be slid in the slot at a second position and be unfolded at a selected angle against the input device for the receiving dock to support the portable electronic device when in use.

Abstract: A portable keyboard comprises a flexible substrate, at least two key groups disposed on the flexible substrate, a circuit board disposed on the flexible substrate, a connector electrically connected to the circuit board and a fixative element having a first connecting portion and a second connecting portion disposed on the substrate. As the flexible substrate is properly tensed to let the first connecting portion join the second connecting portion, the overlapped key groups and the circuit board are all wrapped by the flexible substrate. The folded keyboard is pocket size and easily transported and deployed.
