Abstract: A terminal comprises a terminal body including a pair of terminal plates spaced opposite each other in a height direction, and a pair of elastic contact members arranged on respective inner sides of the pair of terminal plates. Each elastic contact member includes an elastic arm having an extension direction inclined with respect to a length direction of the terminal body. The elastic arms are adapted to clamp to a mating terminal inserted therebetween along the extension direction to achieve electrical connection between the terminal and the mating terminal.

Abstract: A thickness planer has a housing, a motor housed in the housing, a controller having a control board configured to control driving of the motor, at least one intake port provided in the housing, at least one outlet port provided in the housing, an air flow passage that is provided within the housing and configured such that air taken in from the at least one intake port flows therethrough toward the at least one outlet port via the motor, and a fan that is configured to generate flow of air from the at least one intake port to the at least one outlet port through the air flow passage. A particular region of the controller is arranged on the air flow passage.

Abstract: A working machine may be configured to operate with electric power supplied from a first power supply or a second power supply and configured to be used in a state of being in contact with a ground. Each of the first power supply and the second power supply may include a battery cell; a housing configured to house the battery cell; a power cable extending from the housing and configured to discharge electric power; and a connector disposed at an end of the power cable. The housing of the first power supply and the housing of the second power supply may have different shapes from each other. The working machine may include a power supply receptacle to which either the first power supply or the second power supply is configured to be detachably attached; and a connector coupler configured to be coupled with the connector.

Abstract: A thickness planer includes a motor, a planing part, a placing part, a feeding part, and a battery pack mounting unit. The planing part is configured to be driven by the motor and plane a workpiece. A workpiece is placeable on the placing part. The feeding part is configured to feed the workpiece placed on the placing part to the planing part. A battery pack for supplying power to the motor is attachable to the battery pack mounting unit.

Abstract: Disclosed is a composite pellet used as a raw material in a kiln process for the production of phosphoric acid, which is of a core-shell structure with an inner ball encapsulated with a shell, the inner ball mainly consists of a inner ball material and a binding agent, and the shell mainly consists of a cladding material and a binding agent; the inner ball material mainly consists of a carbonaceous reductant powder, and phosphate ore powder and silica powder, the inner ball is combined with the shell through the binding agent to form the core-shell shaped structure. The preparation of the composite pellets comprises the steps of preparing the inner ball, preparing the cladding material, forming, drying and solidifying composite green pellets etc. The composite pellets prepared by the present invention have a smaller range of formulation fluctuation, more stable quality, higher strength and better performance.

Abstract: A rotary kiln for reducing phosphate ore in kiln phosphoric acid process, comprising a kiln body, a kiln head box, a kiln tail box and a driving device for driving the rotation of the kiln body, wherein a fuel burner is provided at the kiln head, a feed pipe and an outlet flue connected to an external hydration tower are provided at the kiln tail box, the upper part of the kiln body is provided with no air pipe, the outlet flue is provided in the radius range of the kiln body with the axis of the rotary kiln as a center, and the fume conveying direction in the outlet flue is substantially parallel to the axis direction of the rotary kiln or has an included angle of less than 45° thereto. The rotary kiln can effectively mitigate the phenomenon of ring forming in the kiln tail of the rotary kiln.
