A cooking chamber assembly in a microwave oven for improved which improves air tightness in the cooking chamber, and reduces assembly complexity, time, and cost. A tray which essentially forms a bottom surface of a cooking chamber of the microwave oven is surrounded by a unitary gasket. A groove formed in an inner edge of the unitary gasket is designed to receive an outer edge of the tray, and a lip formed on an outer edge of the unitary gasket is designed to provide an air tight seal with an inner surface of a case of the cooking chamber. An air duct which guides circulating air is attached to an inner portion of the case with a series of hooks, allowing the air duct to be attached without separate fastening members such as screws or bolts, thus further reducing manufacturing time and cost.

A refrigerator including an improved lower cover. The refrigerator comprises a main body having a storage compartment defined therein, and a lower cover mounted to the lower end of the front part of the main body such that the front part of the lower cover and the front part of the main body together form the same plane, wherein the lower cover is provided with an engaging member bent from the upper end of the lower cover toward the rear of the main body while being extended a prescribed length, the engaging member being successively formed in the lateral direction thereof, and wherein the main body is provided at the bottom part thereof with an engaging groove corresponding to the engaging member of the lower cover, the engaging member of the lower cover being engaged with the engaging groove of the main body. The lower cover is not protruded from the front part of the main body, and fixed parts of the lower cover are not exposed to the outside, whereby an aesthetic appearance of the refrigerator is provided, and formation of a gap between the lower cover and the lower end of main body is prevented.

A fuel gas generation device comprises a compartment containing a solid component and a chamber containing a liquid capable of causing a fuel gas generating chemical reaction when in contact with said solid component. A liquid permeable member is disposed between the compartment and the chamber and in contact with said solid component and a liquid supply system is disposed and arranged for delivering liquid from the chamber to the permeable member at a fixed rate. The device also includes a first chemical reaction space adjacent the permeable member where the fuel gas generating chemical reaction occurs and a second chemical reaction space linked to the first space. The volume of the first space is smaller than the volume of the second space. The device is useful for multiple purposes and generates and supplies a constant amount of fuel gas for mobile and portable fuel cells and the like continuously, stably, conveniently and inexpensively without using pressure adjusting valves and the like. The device includes a system capable of being applied to a wide range of uses for amounts of fuel gas. The operation of the device to maintain a constant reaction rate is based on the concentration of an oxidation catalyst material dissolved in the liquid, the performance of a solid oxidation catalyst material, the liquid supply rate, and/or the size of the surface area of a permeable member in contact with the liquid. The device is useful for maintaining a constant chemical reaction rate regardless or whether the oxidation catalyst is in liquid or solid form.

A test tape cassette is disclosed that includes a cassette housing and an analytical test tape. The test tape includes a plurality of analytical test elements, a spreading fabric for applying a body fluid, and an underlying reagent layer for detecting an analyte in the body fluid. The cassette housing has an application tip that has a guide path extending longitudinally to the test tape in an arched-shape and is uncurved at right angles thereto for supporting the test tape in a kink-free manner. The guide path has an apex area with a central opening that delimits a measuring window for an optical measurement on the test elements.

A metallic cast component (100), which is a housing component, includes a cast body (110) and at least one pipe (120) cored in the cast body (110) and through which a medium (F) is flowable. The pipe (120) includes a pipe connection (121, 122) formed at or in a surface of the cast body (110) on at least one of pipe end of the pipe (120). The pipe (120) also includes, at the pipe end, an enclosing bush (130) embedded in the cast body (110). The enclosing bush (130) effectuating a seal between the pipe end and the cast body (110). A method for manufacturing such a cast component (100) is also provided.

A heat sink that is disposed on a heating element and absorbs the heat generated by the heating element includes: a contact surface to which recessed grooves are formed and the region of which excluding the recessed grooves is in contact with the heating element; insertion members having a thickness, which permits them to fill the recessed grooves, and come into contact with the heating element by being inserted into the recessed grooves; and a turning mechanism that separates the contact surface from the heating element by turning the insertion members in response to a manipulation while abutting the extreme ends of the insertion members against the heating element. With such arrangement, there can be provided the heat sink that can reduce time and effort for removing the heat sink from the heating element while suppressing deterioration of heat absorption capability and an information processing device including the heat sink.

In a method for manufacturing electroactive polymer generators, a strip, including one layer of an electroactive polymer and electrodes applied to sections of this layer, is spirally wound in such a way that multiple electrodes are situated congruently on top of each other, in each case two electrodes situated on top of each other being separated from each other by a layer of electroactive polymer.

The objective of the present invention is to provide a method of forming a pressed paper piece by deep drawing a sheet of blank that is primarily made of paper in use of a punch and a die, and a production apparatus for implementing the method, whereby no distinguishable wrinkles are formed in upright portions of the pressed paper piece. The method of producing a pressed paper piece according to the present invention, implemented when deep drawing a sheet-like blank that is primarily made of paper in use of a punch and a die, includes maintaining a predetermined gap between a first blank holder and the die in an outer peripheral region of a process portion of the blank and applying a pressure to a radially inner region thereof via a second blank holder, thereby reducing wrinkling by an effect of integrated functions exerted in both regions of the blank.
