A collapsible shipping container includes a floor, a roof, and a pair of bifolding sidewalls, that collapse accordion style to place the sidewalls and roof in a configuration wherein the roof is collapsed onto the sidewalls, and the sidewalls are collapsed onto the floor. The container further includes a pair of end walls having upper and lower end wall sections. The upper end wall sections may be lowered by activation of a power source to lie on the roof in the collapsed configuration. Collapse and erection of the shipping container may be accomplished with the aid of auxiliary equipment, such as a fork lift.

The invention relates to a liquid-metal printed circuit board, and in particular relates to a flexible printed circuit board and a preparation method thereof.

The present invention provides a flatbed knitting machine equipped with the movable sinkers, each of which is capable of moderating shape restriction for a torque spring and a sinker even when stresses of the torque spring is prevented from being too large in a sinker opened state, for a part of the movable sinker receiving actions from a sinker jack. A passive arm 11c of a sinker 11 diverges from a portion between a support receive part 11a and a function arm 11b. Even when a sinker jack 12 is made to retreat in the direction of being apart from a needle bed gap 2 and the sinker 11 is made into an opened state, a suppressing pressure from a suppressing part 12d to the other end 13b of the torque spring is weakened, so that a stress of the torque spring can be prevented from being too large in the opened state of the sinker 11. The suppressing part 12d and the leading edge part 12c of the sinker jack 12 need not be made closer to each other and restriction for shapes of the sinker 11 and the torque spring 13 can be moderated.

The present invention relates to a preference determination apparatus, an air conditioning control system, a preference determination method and an air conditioning control method for alleviating constraint for preference determination achievement, alleviating the burden of preference notification for the submitter, and reducing possibility of controlling unstability. A preference determination type air conditioning control apparatus provides a preference determination component, a control plan memory component for storing a control plan, for each of a temporary preference and a continuing preference, that has stipulated a rule for changing the control setting value of the air conditioning in response to said preference for air conditioning from a submitter, a control plan decision component for deciding the control plan that corresponds to the determination result of the preference determination apparatus, as the control plan to be implemented by air conditioning equipment, and equipment control component for controlling air conditioning equipment based on the control plan. The preference determination component provides an input means for receiving a preference for air conditioning from a submitter, and a determination processing means for determining, according to a notification count, whether the preference from the submitter is a temporary preference or a continuing preference.

The invention discloses an optimization method for providing multi-market and local services for a multi-energy virtual power plant, and belongs to the technical field of power demand response. The method mainly comprises the following steps: (1) primary optimization: converting nonlinear and non-convex problems into a mixed integer linear programming problem by using a linearization technology, and carrying out rolling optimization by using real-time information every 24 hours based on a scene; (2) secondary optimization: taking 24 hours as a period, and using real-time information to roll and optimize once again every 30 minutes based on the scene; and (3) three-stage optimization: performing rolling optimization every 5 minutes by adopting second-order cone (SOC) convex relaxation withthe period of 30 minutes based on an optimal power flow (OFP) equation. The litigation method is based on multiple market and local service scenes and a rolling optimization model, modeling is carriedout on the VPP under the condition that uncertainty is considered, local network constraints are relieved through an optimized result, and reactive power support is provided for a power grid.

The invention discloses a MOS power device and a method for forming the same. The MOS power device comprises a first conductive type of voltage-withstand layer, a first conductive type of barrier layer on the voltage-withstand layer, a second conductive type of well region in the barrier layer, first conductive type of source regions in the well region, gates on the barrier layer, a first electrode on the gates and the barrier layer, and a second electrode under the voltage-withstand layer, wherein the barrier layer comprises multiple barrier child layers, the first barrier child layer wraps the well region, the (i+1)th barrier child layer wraps the ith barrier child layer, and the dosage concentration of the ith barrier child layer is greater than that of the (i+1)th barrier child layer. In the MOS power device, the barrier layer is a multi-child-layer structure with gradually changed dosage concentration. Equivalently, multiple barriers are provided so that the on-state voltage drop is decreased, low total amount of doped impurities is achieved, the withstand voltage of the MOS power device cannot be reduced obviously, and a restriction between the on-state voltage drop and the voltage-withstand capability is relieved.
