    摘要： An extrusion molding apparatus for a ceramic molded product which is capable of passing a ceramic material smoothly through a filter unit is disclosed. The extrusion molding apparatus comprises a mold (11) for molding a ceramic molded product, a screw extruder (4) for supplying a ceramic material (80) to the mold (11), and a filter unit (3) for filtering the ceramic material (80) at the extrusion outlet (41) of the screw extruder (4). The screw extruder (4) has built therein a screw (40) for kneading while at the same time leading the ceramic material (80) forward, and further has, on the front part thereof, a spatula portion (5) adapted to move over the inlet surface (30) of the filter unit (3) and there is a predetermined distance D between the spatula portion and the inlet surface (30).

    摘要： A ceramic heater which can be produced easily, induces no increase of production cost and can restrict the resistance change of a heating body due to migration. According to the present invention, a gap is formed between a ceramic sintered body and a heating body. Thus, migration in which cations are seized within the gap is caused so as to impede the cations from entering into the heating body. This makes it difficult for the cations to migrate and the volume in which the heating body is expanded is secured by the gap 13.

    摘要： A gas component detecting element using particles of metal oxide. The particles are prepared and calcined, and then subjected to a treatment which enlarges a specific surface area thereof. Catalyst particles are supported on the surface of these particles, and then the particles are sintered. The gas component detecting element is formed from these particles. A detector formed in this way can be used for a long period of time without any change in characteristics.
