Abstract: The present disclosure discloses a heated throw. The heated throw includes rectangular shawl body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicone key is fixed to a position, relatively close to a corner, on the shawl body. The silicone key is sewn on the shawl body to facilitate an operation and avoid a solution of directly operating by a controller, so that the heated throw is more convenient and fast to use. The electric heating layer and the silicone key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging heated throw state information and user control information with the silicone key through the connector.

Abstract: The present disclosure discloses an electric heating blanket. The electric heating blanket includes a rectangular electric heating blanket body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicon key is fixed to the central position on the electric heating blanket body. The silicon key is sewn on the electric heating blanket body to facilitate operation and avoid a solution of directly operating by a controller, so that the electric heating blanket is more convenient and fast to use. The electric heating layer and the silicon key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging electric heating blanket state information and user control information with the silicon key through the connector.

Abstract: The present application relates to the technical field of household electric appliances, in particular to a novel electric heating covering device, which includes a main controller integrated in a male connector and configured to realize real-time temperature control; an auxiliary controller provided with a built-in control circuit with an MCU and configured to acquire user control information; an auxiliary control power supply and communication line configured to connect the main controller and the auxiliary controller, wherein the main controller supplies power to the auxiliary controller through the auxiliary control power supply and communication line to realize two-way communication; a heating body provided with a heating wire and configured to convert electric energy into heat energy. Therefore, the present application only needs one power line for connection with the mains supply, and completely realizes real-time temperature control.

Abstract: A high-temperature forming device for imperfect single-crystal wafers used for a neutron monochromator includes a heating electric furnace, a temperature control system, a die system, a loading system, a vacuum protection system, and an auxiliary system. Where a furnace mouth of the heating electric furnace faces downwards, the heating electric furnace can be lifted vertically or a hearth of the heating electric furnace can be opened and closed. A vacuum protection cavity is formed by a glass cover and a blocking flange, a through hole is formed in one end of the glass cover, and the other end of the glass cover is closed. An operation opening is formed in the glass cover, the die system includes an upper die, a middle die, and a lower die, the middle die is a composite die.

Abstract: “Grid Plus T Tree” multidimensional index method in memory database partitions the whole record sets to different grid cells. Every grid data unit is connected with one data barrel, which loads records, through the grid directory. Every data unit is only mapped with one data barrel. For memory database, setting up a “T Tree” with these data units according to one field, so as to set up one “T Tree” for each data barrel according to one field. Then the grid directory can be presented by a k-dimensional (the dimension of keyword) array. The field ranges of these data units are called scale. Scale is the memory range of each “T Tree”. This invention successfully overcomes the shortcomings that the current index methods for memory database neither efficiently use the memory space nor suits multi-dimension.
