A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.

The present invention provides a motion mechanism applied to an inward-folding flexible screen terminal, comprising an intermediate support structure, left and right support structures, and left and right movable support plates. The intermediate support structure is provided with a synchronous reverse rotation connecting mechanism. The left and right movable support plates are rotatably connected to the left and right support structures at the intermediate support structure, respectively. Rotation of the left and right movable support plates can be directly planned according to the relationship between gears and racks, and the gear indexing circle diameter can be increased in finite space by using virtual center design, so that the racks are driven to generate a larger sliding distance by rotating a small angle, i.e., sliding a chassis to increase the accommodating space of the screen closed state. Moreover, the effect of accurately controlling sliding is also achieved, and designing a certain transmission ratio by means of the principle of gear and rack transmission to realize the design of the rotation angle can produce the required sliding amount.

A motorized leg (1) is provided with a lower knee member (110), an upper knee member (120), a knee joint mechanism (130) coupling the lower knee member (110) and the upper knee member (120) such that the angle therebetween can be changed, and an extendable device (140) capable of changing the angle between the lower knee member (110) and the upper knee member (120) by extending and contracting. The extendable device (140) comprises a motor (M) and a transmission (T) that transmits power from the motor (M). The transmission (T) comprises a first transmission mechanism (T1) that transmits power from the motor (M) at a first gear ratio, and a second transmission mechanism (T2) that transmits power from the motor (M) at a second gear ratio different from the first gear ratio.

A pulley and a structure having the pulley connected with a driven unit are provided. The pulley includes a wheel portion and a lug portion. The wheel portion includes two circular end surfaces opposing each other and a side surface connecting the two end surfaces. The side surface includes a main arc face and a branch arc face. The branch arc face has a head end connected to the main arc face and a tail end configured to connect a strap. The branch arc face has a width in an axial direction of the wheel portion smaller than a width of the main arc face. The lug portion is fixed to the wheel portion, disposed at a position adjacent to the branch arc face along the width of the main arc face and extends to protrude beyond the branch arc face in a radial direction of the wheel portion.
