Abstract: An IC test device includes a test circuit board and a test fixture. The fixture includes an interposer, a test socket, and a fastener. A protrusion is formed at a bottom face of the interposer, and a space is formed besides the protrusion. A plurality of first contacts is formed at the bottom of the protrusion for soldering with corresponding pads of the test circuit board. A plurality of second contacts is formed on a top face of the interposer and electrically connected to the first contacts. The socket defines a guide groove for receiving an IC. A plurality of conductors are arranged corresponding to the guide groove and extend through the test socket. Each conductor has a bottom end electrically connected to one corresponding second contact and a top end for contacting a pin of the IC. The fastener is mounted on the test socket to press the IC.

Abstract: A monitoring system for turbulence of the atmospheric boundary layer under a wind drift sand flow environment includes: a meteorological tower, a hot-wire bracket and a plurality of observation frames, which are vertically and cooperatively arranged in parallel. The hot-wire bracket is arranged close to the meteorological tower, and the plurality of observation frames are symmetrically distributed on the two sides of a region formed by the meteorological tower and the hot-wire bracket. The meteorological tower is cooperatively provided thereon with a first group of experimental instruments for measurements; the hot-wire bracket is cooperatively provided thereon with a hot-wire probe assembly; and each observation frame is cooperatively provided thereon with a second group of experimental instruments for measurements.

Abstract: A method for processing a device shell, includes: applying an ink layer onto a film to form a membrane; attaching the membrane to an outer surface of the device shell; and removing the film from the membrane attached to the outer surface, such that the ink layer remains on the outer surface.

Abstract: A monitoring system for turbulence of the atmospheric boundary layer under a wind drift sand flow or sand dust storm environment comprises: a meteorological tower (6), a hot-wire bracket (9) and a plurality of observation frames (10), which are vertically and cooperatively arranged in parallel. The hot-wire bracket (9) is arranged close to the meteorological tower (6), and the plurality of observation frames (10) are symmetrically distributed on the two sides of a region formed by the meteorological tower (6) and the hot-wire bracket (9). The meteorological tower (6) is cooperatively provided thereon with a first group of experimental instruments for measurements; the hot-wire bracket (9) is cooperatively provided thereon with a hot-wire probe assembly (8); and each observation frame (10) is cooperatively provided thereon with a second group of experimental instruments for measurements.

Abstract: A view definition enhancement system for gastrointestinal endoscope diagnosis and treatment (ESCGV) comprises a washing bottle (1) and a liquid delivery pipe (2) led out from the washing bottle (1). The liquid delivery pipe (2) pumps washing liquid to a liquid inlet system of a gastrointestinal endoscope or an observation window of the gastrointestinal endoscope through a first peristaltic pump (3); and the washing bottle (1) is further provided with a stirring and heating subsystem capable of stirring and heating the washing liquid. A view definition enhancement method for gastrointestinal endoscope diagnosis and treatment comprises steps of: 1) adding the washing liquid into the washing bottle (1); 2) magnetically stirring the washing liquid in the washing bottle (1), and heating the washing liquid at the same time; 3) setting the temperature of the washing liquid to 25-38° C.; and 4) delivering the washing liquid into the observation window of the gastrointestinal endoscope.

Abstract: The multifunctional shoes for walking and skating with single roller mainly include a pulley assembly and the shoe body. The pulley assembly consists of a bracket, a roller, a shaft, pushing rods, springs, pushing rod assembly and fastening bolts. The shaft passes through the center of the roller fixing the roller in the slots of the bracket. The pushing rods and the springs are provided on the top of the bracket with the pushing rod assembly provided in the bracket. The pulley assembly is secured to the shoe by fastening bolts. The pushing rod assembly includes a pushing rod head, a rear connecting plate, springs, connecting bolts of the pushing rods, pushing rods, a front connecting plate and fastening bolts with the pushing rods connecting bolts and pushing rods welded to the front connecting plate while the springs seated on the connecting bolts of the pushing rods. The roller can be extended and retrieved in the direction perpendicular to the ground.

Abstract: An assembly type skateboard-ramp includes several groups of ramp, two sides of which have swallow-tailed tongue and groove joints respectively. The ramp has a curve face and an opposite vertical face. Each group of ramps has same form and gradually decreased size. The swallow-tailed tongues of ramps of a group are inserted in corresponding swallow-tailed grooves of ramps of another group. These skateboard-ramps can be assembled and disassembled.

Abstract: A shoe with elastic sole is disclosed. The shoe comprises an inner sole, an outer sole, an upper, and an elastic sole comprising a U-shaped cavity that has openings at the two lateral sides of the sole and a U-shaped spring pad made of carbon fiber plate provided in the cavity and between the inner sole and outer sole forming a highly elastic sole structure. A U-shaped spring tab is added to the core of the U-shaped portion of the U-shaped spring pad. Alternatively, the openings of the cavity at the two lateral sides of the sole can be closed, forming a totally enclosed cavity structure. Additionally, another U-shaped cavity with a U-shaped spring pad can be provided in the anterior portion of the sole, thus forming a sole structure with U-shaped spring pads both in the anterior and heel portion of the sole. A ventilation structure is provided between the inner sole and the outer sole.
