Abstract: A nail blocking member for a nail gun. The nail gun includes a firing portion for firing a nail. When an object is pressed upon the nail blocking member by the firing portion, the nail is fired by the firing portion to enter the object. The nail blocking member includes a main body having a contact face, with a formation groove concavely disposed on the contact face, and a guiding block protruding from the formation groove. An object is pressed upon the contact face by the firing portion, and a nail is fired by the firing portion to enter the object to hit the guiding block, such that the nail is guided by the guiding block to move toward the formation groove, so as to be bent along the formation groove and reversely folded back into the object.

Abstract: A nail gun structure includes a body portion including a punch portion; an air cylinder between the body portion and a swaying clamp arm, and having a telescopic rod pivotally connected with the clamp arm, the air cylinder having a piston, a first bore and a second bore disposed along an axial direction of the telescopic rod, the piston connected with the telescopic rod and reciprocating to control the communication of the second bore; and a control valve disposed between the air cylinder and the body portion, and having a tube set connected with an air source and also between the air cylinder and the body portion. When the air source and the tube set communicate with the first bore, the piston moves to allow the communication of the second bore. After the clamp arm clamping a wooden board, the punch portion punches to launch the nail.

Abstract: A clamping device comprises a fixing frame for assembling to a nail gun, a clamping arm pivoted to one side of the fixing frame and swung relative to a nail output of the nail gun connected to the fixing frame, a cylinder having a telescopic rod and linked to the clamping arm, and a pipeline fluidly communicated with the cylinder and a pneumatic supply. The fixing frame is fixed corresponding to the nail output so as to easily assemble and disassemble. An air pressure through the pipeline is driving the telescopic rod and the clamping arm to swing relative to the fixing frame. A lay-up is clamped by the clamping arm to abut against the nail output for nailing and piercing. It may be easily detached from the nail gun after finishing constructing so that the multiple functions of the nail gun may be achieved.

Abstract: A barrel assembly of a nail gun comprises a sleeve member, a cover member, a bush, and a firing pin. The sleeve member is connected with the gun body and includes a chamber, a firing hole, and a transporting portion. The cover member is covered at the end of the sleeve member having the firing hole. Two ends of the bush are respectively inserted into the fireproof groove and protruded from the cover member. A limit hole is passing through the bush for fluidly communicating with the firing hole. Two ends of the firing pin are respectively connected with the gun body and inserted into the chamber of the sleeve member. The gun body is operated to drive the firing pin to shift in the chamber, and further firing the nails through the firing hole toward the limit hole of the bush to send out.

Abstract: A tie locking device includes a main body and a rotatable press cover. The main body includes a fixing section and at least one wall connected with the fixing section. The press cover has a pivoted end pivotally connected with a pivoted section of the main body. The pivoted end of the press cover and the pivoted section of the main body together define an inlet for a tie to enter the main body. A valve board is disposed on the main body and movable within the main body between a first position distal from the inlet and a second position proximal to the inlet. The valve board is formed with a toothed section. After the valve board is moved to the second position, the toothed section bites the tie and the press cover is pressed onto the main body to fix the valve board and the tie.

Abstract: A method of single photon emission computed tomography (SPECT) using dual-isotopes of [99mTc]TRODAT-1 and [123I]ADAM is provided. Through SPECT, anomalies in dopamine and serotonin system are diagnosed with their photos in one examination. Thus, cost and labor for two examinations are saved and uses of SPECT are reduced.

Abstract: A lutetium-based phosphor having the chemical formula: xLu3Al5O12.yGd3Al5O12:CePrEuTb, and being capable of radiating reddish orange-red spectrum when activated by a shortwave light emitted by an InGaN light-emitting diode. The invention also discloses a warm white LED using the lutetium-based phosphor that produces orange-red light having the peak wavelength ?max>560 nm, half width>125 nm and color rendering index Ra?75 when activated by the LED radiation ?=420˜500 nm.

Abstract: Pick-resistant handcuffs having two fixed, arc-shaped hooks and one pivotable, arc-shaped hook. The two fixed ring hooks engage each other to form an accommodation chamber for receiving the pivoting hook penetrating into an open side of the accommodation chamber. Central channels are cut in the teeth outer periphery and accommodate a stop projecting part between the lateral edges of the teeth that inhibits unlocking the stop members of the ratchet attached to the two fixed hooks. Elastic members biased toward the teeth are disposed on either side of the stop projecting part act independently to provide ratchet stops to each tooth edge, and the stop projecting portion blocks insertion of a pick and unlock both of the two ratchets simultaneously.
