In a breather system for a fuel tank having a tank body, a fuel supply port opened and closed by a fuel cap provided in a central portion of an upper wall of the tank body, wherein an upper end of a breather pipe is located to face a central portion of a fuel supply port. When the fuel supply port is closed by the fuel cap, a breather chamber is formed in the fuel cap and the breather chamber communicates with the breather pipe. Thus, when the fuel tank is inclined, fuel is prevented from entering the breather pipe, and the fuel supply port is not immersed in the fuel, thereby maintaining the sealability of the fuel supply port.

A sealing device for a rolling bearing device includes a metal core which includes a cylindrical portion fitted on an outer circumferential surface of an end portion of an outer ring, a circular ring portion extending radially inwards from the cylindrical portion while being in abutment with an end face of the end portion of the outer ring and an inward edge portion extending further radially inwards from a radially inward end portion of the circular ring portion so as to protrude towards an inner circumferential side of the outer ring and on which seal lips are mounted. A shielding portion made of an elastic material is mounted at a radially outward end portion of the circular ring portion in such a manner as to extend towards a flange portion so as to shield a clearance defined between the flange portion and the end portion of the outer ring.

The time period during which a wafer is stabilized to a predetermined temperature by increasing a thermal conductivity of a junction layer for bonding an electrostatic chuck layer and a support together, and the deterioration of the junction layer that is caused by active species generated by plasma is suppressed. Between the electrostatic chuck layer formed by sintering together a chuck electrode made of tungsten and an insulating layer made of alumina and the support, made of aluminum, for supporting the electrostatic chuck layer, the junction layer is provided to bond the electrostatic chuck layer and the support together. The junction layer is formed by impregnating a porous ceramic with a silicone-based adhesive resin. Further, rubber or a heat shrink tube made of a fluoric resin such as PFA is provided as a soft coating member so as to coat a side circumferential surface of the junction layer and the side circumferential surfaces of the electrostatic chuck layer and the support come into a tight contact with the heat shrink tube or rubber.

A radar level gauge for determining the filling level of a product in a tank, comprising a transceiver for transmitting and receiving microwaves, processing circuitry connected to the transceiver and adapted to determine the filling level, an antenna connected to said transceiver and arranged to emit and receive microwaves through an opening of the tank, and a microwave transmissive sealing member adapted to cover said opening and to provide pressure sealing of the tank. The sealing member comprises a metal grid layer providing structural strength, which metal grid layer has sealed openings formed to allow transmission of microwaves.The tank opening is thus divided into a number of smaller openings by the metal grid, thereby improving the mechanical strength of the sealing member. At the same time, the sealing member is designed to maintain its pressure sealing properties, e.g. by suitable dielectric filling of the openings.

The present invention provides a battery module. The battery module is formed by laminating a plurality of rectangular cells (10) and holders (20) and connecting them with the end plates at the outer side of the parallel direction thereof through jointing members to inhibit the projection deformation of a plurality of cells (10). The joining members (60, 70) join the first and second end plates (50, 51) to fasten the plurality of rectangular cells and the holders to be a single unit. Ends of the joining members are fastened to first securing parts (52u, 54u) and second securing parts (53u, 55u) on the first and second end plates. The first securing parts and the second securing parts are disposed at both ends of a center line (C-C) that penetrates through centers of the plurality of rectangular cells, the holders, and the first and second end plates. A distance between the center line and each of the first and second securing parts is smaller than a distance between each of the first and second securing parts and each of outermost surfaces of the first and second end plates.

Disclosed herein is a plate-shaped secondary battery constructed in a structure in which an electrode assembly of a cathode / separator / anode structure is mounted in a battery case, and the battery case is sealed by thermal welding, wherein the secondary battery has at least one valve (one-way exhaust valve), having a small thickness, mounted at a sealed portion, formed at the outer circumference of an electrode assembly receiving part of the battery case, for allowing internal high-pressure gas to be exhausted out of a battery cell and preventing external gas from being introduced into the battery cell. The secondary battery according to the present invention has the effect of effectively exhausting internal high-pressure gas generated during the abnormal operation of the battery, such as overcharge, out of the battery case, while maintaining the sealability of the battery case, thereby simultaneously improving the efficiency and safety of the battery.
