The present invention provides a novel fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, for example by way of application of Pulse Electro-Thermal Deicing/Defrosting (PETD) or equivalent technique thereto, by configuring it to increasing its resistance to a value at which the system's reactance at its working frequency is comparable to, or less than, its electrical resistance. Advantageously, the inventive system may be advantageously configured to comprise the same form factor and interface as a conventional fins-on-tubes type evaporator/heat exchanger component, such that the inventive evaporator/heat exchanger system may be readily utilized for replacement thereof.

A laminate packaging flat cell comprises a laminate film formed by combining polymer and metal with each other; a power generating element formed of a plurality of electrode plates and separators, and hermetically sealed by the laminate film; and an electrode terminal lead coupled to the electrode plate. In the laminate packaging flat cell of the present invention, the power generating element is hermetically sealed by forming a thermally welded portion on an outer periphery of the laminate film, and the electrode terminal lead protrudes from the thermally welded portion, and a through-hole is provided in a position thereof contacting the thermally welded portion.

The ballistic structure for personal protection according to the present invention includes a plurality of rigid structures, separated from one another, in which at least one rigid element is formed by layering of leaves made of high molecular weight polyethylene tapes arranged in parallel and unidirectional fashion wherein these leaves are cross-plied and pressed at high temperature, with adhesive polymers being laid down on at least one face of the single leaves, and in which at least another rigid element is formed by a layering of unidirectional resin-impregnated yarns, wherein each layer of unidirectional yarn is crossed with the subsequent one. Such layering is pressed at high pressure and at high temperature. In a preferred embodiment, the rigid structure, which is the first to be impacted by the bullet, is made of a rigid element composed of ultra high molecular weight polyethylene yarn. The values of trauma obtained by the bullet impact are considerably reduced with respect to a monolithic layering of the same weight.

Disclosed is a wooden electric piano keyboard with a cantilever type structure. Each white key (1) and each black key (2) are mounted on a chassis through a front stop block (6) and a middle stop block (8). A support (12) is fixed at one end, which is away from a player, of the chassis (7). A rear stop block (10) is disposed on the support (12) and located under one end, which is away from the player, of each white key (1). The support is also provided with a cantilever shaft (11). One end of a cantilever bar (4) is provided with a cantilever shaft sleeve (15), and the other end of the cantilever bar (4) is provided with a counterweight block (3) to adjust the weight of the cantilever bar (4). The cantilever shaft sleeve (15) is sleeved on the cantilever shaft (11). A clamping nail (9) is fixed in an opening formed on the cantilever bar (4), and one end of the clamping nail (9) is disposed on an upper surface of the end, which is away from the player, of each white key (1). The support is (12) also provided with an upper stop block (5), and the upper stop block (5) is located above the other end of the cantilever bar (4) and deviated to a direction away from the player. According to the wooden electric piano keyboard, playing touch sense of conventional pianos can be realistically simulated.

The invention discloses an omnidirectional wheel, a moving device and a control method of the moving device, belonging to the field of intelligent tools for riding instead of walk. The omnidirectional wheel comprises a center wheel and a plurality of peripheral wheels which are arranged in an arrayed mode along the circumference by taking the axis of the center wheel as an axle center, wherein a peripheral wheel braking assembly is arranged on the center wheel, and the peripheral wheel braking assembly can control the resistance when the peripheral wheels rotate. By arranging the peripheral wheel braking assembly for controlling the resistance when the peripheral wheels around the center wheel rotate on the center wheel, the problems in the related technology that the motion of the moving device in a braking process can not be controlled because of other reasons and the braking performance is relatively low are solved, thereby achieving the effects of increasing the resistance when the peripheral wheels rotate by the peripheral wheel braking assembly and preventing the peripheral wheels from rotating randomly.

A transparent conductive film includes a metal filler and a colored self-assembled material adsorbed to the surface of the metal filler. This transparent conductive film can prevent diffuse reflection of light on the surface of the metal filler.

A semiconductor memory device (1) has a FET (10) (first field-effect transistor), a FET (20) (second field-effect transistor), a contact plug (32) (first conductive plug), contact plugs (34) (second conductive plugs), and a detection circuit (50). The FET (20) is provided in a double well (40). M (m is a natural number) contact plugs (32) are connected to a diffusion layer (22) of the FET (20) while n (n is a natural number) contact plugs (34) are connected to a diffusion layer (24). Here, m is smaller than n. The detection circuit (50) detects the difference between the output of the FET (10) and the output of the FET (20).

An composite heater is disclosed. The heater may include a base additively manufactured from a first matrix material, and a heating element additively manufactured adjacent the base from a second matrix material and an electrically and thermally conductive fiber that is at least partially encased in the second matrix material.

A sealing device (1) in which, even when a seal member (6) having a core metal (4) and a sealing section (5) is fitted on a piston member (3) that axially reciprocates in a bottomed circular cylinder (2), force required for the fitting can be suppressed to a low level and as a result the core metal (4) of the seal member (6) is not deformed. The wall thickness of a circular cylindrical portion (42), fitted on the piston member (3), of the core metal (4) is reduced to provide the circular cylindrical portion with spring properties. Alternately, slits (44) are equally arranged on the circumference of the circular cylindrical portion (42) of the core metal (4) or, alternatively, the circular cylinder portion (42) is constructed from claws (45).
