The present invention is directed to a stationary medical boom that can be easily installed on the floor of an existing operating room and that has one or more articulated arms used to position audio, video and medical equipment over an operating table in an operating room. The boom includes a stationary base configured to be attached to the floor of the operating room. One or more articulated boom arms are supported by the stationary base and extend out over the operating table. Articulated appendage arms, extending from the boom arms, are configured to support the audio, video and other medical equipment used in the operating room in the vicinity of the operating table. Both the articulated boom arm and the articulated appendage arm can be moved in either the X and / or Y directions. Consequently, the equipment supported by the appendage arm can be moved in virtually any position around the operating table.

The invention belongs to the technical field of clinical in-vitro detection and particularly relates to protein-free coated plate confining liquid. The protein-free coated plate confining liquid contains Tris-HCL buffer liquor with PH of 7.4, a macromolecular substance, a surfactant, mycose and sodium azide, wherein the macromolecular substance is one or a mixture of two of PEG (Polyethylene Glycol)-20000 and polyvinyl pyrrolidone. The coated plate confining liquid disclosed by the invention not only can be combined with a blank position on the surface of the coated plate to achieve a confining effect for the coated plate, but also can keep biological activity of antigen / antibody on the surface of the coated plate longer after the coated plate leaves a low-temperature environment. The confining liquid provided by the invention is protein-free confining liquid, low in cost, simple to operate, stable in properties, shorter in sealing time in comparison with BSA (Bull Serum Albumin), and capable of achieving the effects of lowering cost and stabilizing the coated plate.

The present invention relates to an injection nozzle (1) for an internal combustion engine, in particular in a motor vehicle. A first nozzle needle (3) controls at least one first injection opening (5). A second nozzle needle (4) controls at least one second injection opening (6). A control chamber (32) is connected via a throttle line (35) to a pressure chamber (34) in which it is possible to adjust the injection pressure. A first control piston (41) cooperates with a first needle unit (17) that includes the first nozzle needle (3) and the first control surface (43) of this first control piston (41) can be acted on by the control pressure prevailing in the control chamber (32). In the closed position of the first nozzle needle (3), there is an axial play (44) between the first control piston (41) and the first needle unit (17). A second control piston (42) cooperates with a second needle unit (30) that includes the second nozzle needle (4) and can be acted on with the control pressure on a second control surface (45). In a closed position of the second nozzle needle (4), the second control piston (42) rests against the second nozzle needle (4) on the second needle unit (30). At middle to high pressures in the pressure chamber (34), both nozzle needles (3, 4) can close quickly. With a rapid pressure increase in the pressure chamber (34), the second nozzle needle (4) can open quickly and the two nozzle needles (3, 4) can close quickly. With a relatively low to middle speed pressure increase in the pressure chamber (34), the second nozzle needle (4) does not open or only opens at a higher pressure.

An image capturing unit captures a periphery of a moving body through a transmitting portion. A heater is capable of heating the transmitting portion. An air-conditioning unit switches an air-conditioning state in the moving body between an inside air circulation state and an outside air introduction state. A control unit controls the heater. The control unit can make the heater operate intermittently, and perform control so that an OFF time of the heater during an intermittent operation will be shorter in the case in which the air-conditioning state is set to the inside air circulation state than the case in which the air-conditioning state is set to the outside air introduction state.
