Abstract: A vertical tire changer with a double-sided tool and an overturning structure is provided. The vertical tire changer includes a pedal, a base, an operating platform, a pulley, a double-sided tool rotating structure, a small pressing wheel structure, a large pressing wheel structure, a lifting seat and a rotating chuck. A wheel hub is clamped above the rotating chuck so that the rotating chuck rotates to a horizontal position. The ends of the double-sided tool rotating structure are provided with a straight hook portion and a bent hook portion respectively. The straight hook portion is configured for tire mounting, and the bent hook portion is configured for tire dismounting. The small pressing wheel structure and the large pressing wheel structure can both be contracted and extended in the using process. The small pressing wheel structure and the large pressing wheel structure play an auxiliary supporting role.

Abstract: A combined tire-disassembling device is provided, and includes a first shaft with a pressing wheel at an end of the first shaft, and a second shaft with a disassembling and assembling hook at a first end of the second shaft, where a combined frame is provided on the first shaft, a shaft hole matched with the second shaft is provided in the combined frame, one end of a driving oil cylinder of second shaft is connected with the second end of the second shaft, and the other end of the driving oil cylinder of second shaft is connected with the combined frame. A large horizontal tire changer is further provided, which includes a base platform, a sliding platform provided at one end of the base platform, a chuck assembly and a tire disassembling mechanism a hydraulic driving device and an operating console.

Abstract: An inductor magnetic core and an inductor using the same are disclosed. The inductor magnetic core includes a middle column, an upper yoke, a lower yoke, and at least two high magnetically-permeable side columns. The middle column is disposed between a middle part of the upper yoke and a middle part of the lower yoke, a coil is wound the middle column, and a saturation magnetic flux density of the middle column is higher than that of the upper yoke and the lower yoke. The at least two high magnetically-permeable side columns are disposed in interval between the upper yoke and the lower yoke, and two ends of each high magnetically-permeable side column are connected to outer edges of the upper yoke and the lower yoke, respectively. The inductor magnetic core and the inductor of the present invention improves utilization of the yoke, and also provide compact structure and simple production.

Abstract: The present invention discloses a tire disassembly and assembly booster arm device installed on an upright of a tire disassembly and assembly machine. The tire disassembly and assembly booster arm device includes a first tire pressing arm and a second tire pressing arm. A first polished shaft and a second polished shaft are symmetrically arranged on two sides of the upright. An air cylinder hanging frame is installed on the top surface of the upright, and an air cylinder is suspended on the air cylinder hanging frame. One end of a piston rod of the air cylinder is connected to a sliding frame connecting frame. A first sliding frame is connected to the first polished shaft in a sliding mode. The front end of the first sliding frame is hinged to the first tire pressing arm, and the rear end of the first sliding frame is connected to one side of the sliding frame connecting frame. A second sliding frame is connected to the second polished shaft in a sliding mode.

Abstract: Assay devices comprising substrates functionalized to comprise probe species on multiple separate regions are provided. Ten thousand to a hundred thousand separate regions can be provided in a substrate of one square centimeter. The separate regions can comprise separate probe species, or in another embodiment, multiple different probe species can be present on each single functionalized region. The probe species are selected to be specific for binding to target species of interest in a sample. Methods and systems for making these devices are also provided. The devices are useful, for example for assaying molecules in a human sample that are reactive to a large number of different allergens placed on the substrate.
