There is provided an extrusion head that is capable of largely increasing a production speed rather than a conventional head that extrudes supplies a high viscous melt-coating composition. In an extrusion headthat comprises a die ringhaving an exit portionand a nipplearranged in vicinity of the exit portion, whereby a core wire passageis provided to an inside of the nipplein an axial direction, and a high viscous melt-coating composition is pressure-fed into a space, which is formed by the die ringand the nipple, toward the exit portionwhile drawing out a core wire W from the core wire passage to the exit portion, and thus a cord-like coated core wire is extruded from the exit portionof the die ring while coating the core wire W with the high viscous melt-coating composition, a stagnation reservoir of the high viscous melt-coating composition is provided in vicinity of the exit portion by providing a wall surfaceperpendicularly to a proceeding direction of the core wire W at the exit portion

The present invention relates to a separator and spacer for use in non-aqueous inorganic electrolyte cells using oxyhalides as both a solvent and cathode active material, and an alkali metal as anode active material. There is provided a non-aqueous inorganic electrolyte cell which has a good discharge performance, preservability, and a safety to resist the charging at 5 V caused due to erroneous operations and accidents, by specifying a content of glass involved in the separator made of mainly glass fibers, specifying the type of synthetic resin of other components than glass fibers, or by specifying an oxyhalide absorbance of materials from which the separator and the spacer are produced.

For the preparation of a catalytic composite for purifying exhaust gases, first, at least one perov-skite-type compound oxide of the formula RMO.sub.3, where R is La or a combination of La and Ce, and M is Co, Mn or a combination thereof, is supported together with cerium dioxide and alumina sol on a heat resistant carrier made of an inorganic oxide selected from the group consisting of cordierite and mullite, and then iron and palladium are further supported together thereon. As a result, a catalytic composite having a high degree of oxidation activity at low temperatures and also having excellent heat resistance can be obtained.

A catalytic composite for purifying exhaust gases is disclosed which comprises ceramic fibers, oxidation catalysts supported on the surface of the ceramic fibers and in the interstices between the ceramic fibers, and inorganic binders for binding the oxidation catalysts to the ceramic fibers, the catalytic composite being provided with vent holes for the passage of exhaust gases. Also disclosed is a method for preparing the catalytic composite.

The invention relates to a nonaqueous electrochemical cell comprising an alkali metal anode, an oxyhalide or other cathode-electrolyte solvent which is liquid at ambient temperature, and a porous carbonaceous cathode collector, the cathode-electrolyte containing at least polyethylene terephthalate as an additive for minimizing the voltage delay, i.e. a large voltage drop in an initial stage of discharge.

A self-cleaning type cooking oven with a cooking chamber which has a function to pyrolytically eliminate food soils accumulated on walls of the cooking chamber. The cooking oven includes a heater for supplying heat into the cooking chamber so as to allow to pyrolytically degrade the food soils and an exhausting passage coupled to the cooking chamber to exhaust gases generated due to the pyrolytical degradation to an ambient atmosphere. In the exhausting passage is provided an oxidizing catalyst which oxidizes the gases introduced thereinto for exhausting and also provided a gas sensor to detect a gas component therearound. Also included in the cooking oven is a heat control unit electrically connected to the heater for controlling heat supply into the cooking chamber, the heat control unit being responsive to a gas signal therefrom to determine a heating time period for chamber cleaning. With the temperature of the cooking chamber being kept at a predetermined cleaning temperature, the heat control unit samples the gas signal at a given time interval to detect a variation of amount of the gas component and detect an inflection point from decreasing to increasing or vice versa in the gas-component variation to determine the heating time period in conjunction with the inflection point, the food soils being substantially degraded by heating during the heating time period.

An oxygen conductive solid electrolyte plate has first and second opposite surfaces, First and second electrodes fixedly extend on the first and second surfaces of the electrolyte plate respectively. A spacing frame hermetically secured to the first surface of the electrolyte plate surrounds the first electrode. The spacing frame has an opening. A sealing plate hermetically secured to the spacing frame defines a chamber in conjunction with the electrolyte plate and the spacing frame. The chamber accommodates the first electrode and opens into an environment only via a window defined by the opening in the spacing frame. The window allows oxygen molecules to flow from the environment into the chamber by diffusion.
