摘要： A plate heat exchanger gasket includes an elongate body and a first number of elongate projections projecting from an upper side of the body and extending along the gasket's longitudinal extension. Each projection is defined by a top and two opposing flanks extending from the top. Referring to a cross section perpendicular to the gasket longitudinal extension, for each of a second number of unsymmetrical projections of the projections, a first area defined by an outer flank of the flanks, the body upper side and a normal of the body upper side extending through the top of the unsymmetrical projection, is smaller than a second area defined by an inner flank of the flanks, the body upper side and the normal of the body upper side extending through the top of the unsymmetrical projection. This normal is displaced from a center normal of the body upper side.

摘要： Embodiments relate to a Gaussian synapse device configured so that its transfer characteristics resemble a Gaussian distribution. Embodiments of the Gaussian synapse device include an n-type field-effect transistor (FET) and p-type FET with a common contact so that the two FETs are connected in series. Some embodiments include a global back-gate contact and separate top-gate contact to obtain dual-gated FETs. Some embodiments include two different 2D materials used in the channel to generate the two FETs, while some embodiments use a single ambipolar transport material. In some embodiments, the dual-gated structure is used to dynamically control the amplitude, mean and standard deviation of the Gaussian synapse. In some embodiments, the Gaussian synapse device can be used as a probabilistic computational device (e.g., used to form a probabilistic neural network).

摘要： A power conversion device that performs power conversion between a DC circuit and an AC circuit includes a power conversion circuit including a plurality of sub-modules, a failure detection device that detects an internal failure of the power conversion circuit, and a control device that generates an operation command controlling operation of each of the plurality of sub-modules. The control device acquires a voltage value of a capacitor included in each sub-module, calculates a deviation between a variance value indicating a variation in the voltage value of the capacitor included in the sub-module in a reference period and a reference variance value in the sub-module for each of a plurality of sub-modules, determines a failure section of an internal failure based on the deviation in each sub-module when the internal failure is detected, and outputs an operation command based on a determination result to each sub-module.

摘要： A lead member includes a plurality of lead terminals, and the lead terminals extend from the inside to the outside of a mold resin. Each of the lead terminals has a base portion and a tip end portion on the outside of the mold resin. The base portion is disposed on a region side having a semiconductor element and extends in a direction protruding from the mold resin. The tip end portion extends in a direction different from the base portion and is disposed on the opposite side to a region having the semiconductor element as viewed from the base portion. The length by which the base portion extends differs between a pair of lead terminals adjacent to each other, among the lead terminals. At least a surface of the base portion of each of the lead terminals is covered with a coating resin.
