A heater including a plurality of first dielectric vanes and a plurality of second dielectric vanes arranged about a longitudinal axis, each first dielectric vane and second dielectric vane having a plurality of wire guiding grooves, a heater wire structure wound around the first and second dielectric vanes in wire guiding grooves, and wherein the heater wire structure substantially avoids contact with bottoms of the wire guiding grooves of the second dielectric vanes.

A heater comprises a cap 20 formed by joining and fixing together curved peripheries 10a as peripheries of two semi-elliptical heat-generator-containing sheets 10 of generally the same shape. The heat-generator-containing sheet 10 comprises a waterproof inner layer sheet 2, an air-permeable sheet 5 disposed so as to cover the entire surface of the inner layer sheet 2, and a plurality of heat generators 3 interposed between and held by the inner layer sheet 2 and the air-permeable sheet 5, which ...

A rod-shaped heater provided is composed of a carbon wire heating element 2 sealed in a small or large diameter quartz glass tube, a small diameter quartz glass tube portions 3a and 3b charged with compressed wire carbon members at opposite ends thereof; a sealed terminal section 10 having connection lines 11a and 11b for power supply held between the compressed wire carbon members charged in the small diameter quartz glass tube. The connection lines and the carbon wire heating element are elect...

A heater includes a heating member formed in a plate shape that includes a substrate-heating surface on which a substrate is mounted and a heating member rear surface which is on the opposite side of the substrate-heating surfaces. The heater also has a resistance heating element embedded therein. An auxiliary member is placed on the side of the heating member rear surface of the heating member and has an opposing surface which opposes the heating member rear surface. A planar gas path for gas e...

A heater having a substrate composed of a heat-resistant and electrically insulating material, a heater element formed on the surface of the substrate in a belt-shape in the longitudinal direction containing an alloy of Ag and Pd having a weight ratio Ag/Pd of 90/10 to 70/30, glass, and an inorganic oxide and/or an inorganic nitride of 0.1 to 20 wt % to the weight of the alloy of Ag and Pd, and a power supply terminal part formed in connection with the heater element. The heater is suited to use...

A heater has a cylindrical metallic shell, a heater body partly disposed in a front end portion of the metallic shell, an electrode disposed in a rear portion of the metallic shell and electrically connected to the heater body, and a terminal adapted to be capped with an electric connector. The terminal includes a terminal body for power supply to the heater body through the electrode and an engaging portion formed on an outer circumferential surface of the terminal body so as to be engageable w...

A generally rectangular shaped heater having an open front and a pyramid shaped roof is designed with a double wall at its rear section. Air is blown into the cavity between the two walls where it absorbs heat and is thereafter expelled through ducts which project through the front of the heater. A grate is recessed in a horizontal opening below the open front of the heater and damper means are provided to admit air below the grate and thereby facilitate the combustion of the material deposited ...

The invention relates to a heater (1) for use in a room of a dwelling, preferably with a convection surface (3) and, in the case, for example, of a hot-water heater, with a water tank with an inlet and an outlet aperture. To obtain a design more advantageous concerning the use, the heater according to the invention has a separate closed storage chamber (7) containing a latent heat storage medium (8), the storage chamber (7) being heatable by radiation, convection or electrically.

Connecting conductors located within at least one heating field for heating conductors are configured so that they do not luminate in operation and are not bowed or shifted out of place by thermal loading. For this purpose the conductor is corrugated and also securely anchored at regular center-spacings, it having with respect to the heating resistor greater resistance cross-sections. This achieves for a very simple construction an optically advantageous glow pattern of the heater in every opera...
