    摘要: A ceramic honeycomb catalyst carrier wherein a porosity is 20% or less and an average surface roughness (Ra) of a partition wall of the carrier is 0.5 &mgr;m or more is obtained by forming ceramic raw materials to obtain a ceramic honeycomb formed body; drying the ceramic honeycomb formed body to obtain a ceramic honeycomb dried-up body; roughening a surface of the partition wall of the ceramic honeycomb dried-up body by exposing the ceramic honeycomb dried-up body in an airflow in which polishing powders are included; and sintering the ceramic honeycomb dried-up body after a surface treatment, or, by forming ceramic raw materials to obtain a ceramic honeycomb formed body; drying and sintering the ceramic honeycomb formed body to obtain a ceramic honeycomb sintered body; and roughening a surface of the partition wall of the ceramic honeycomb sintered body by exposing the ceramic honeycomb sintered body in an airflow or a water flow in which polishing powders are included.

    摘要: A process for producing a cordierite-based ceramic honeycomb structure, includes kneading raw materials for cordierite with a forming aid to obtain a raw material batch, subjecting the raw material batch to obtain a honeycomb structure, and subjecting the honeycomb structure to drying and firing in this order to obtain a ceramic honeycomb structure whose crystal phase is composed mainly of cordierite. The raw material batch contains 65% by weight or more of raw materials for cordierite, comprising talc, kaolin and aluminum hydroxide and having crystal water. The kaolin has an average particle diameter of 5 &mgr;or more and a BET specific surface area of 10 m2/g or less and is contained in the raw material batch in an amount of 10% or more by weight. Formability during extruding, particularly lubricity and shape stability, are improved, for producing cordierite-based ceramic honeycomb structure having thin partition walls and high cell density, and improved mechanical strength (isostatic fracture strength) and improved catalyst coatability.

    摘要: A picture processor for a video conference device, etc., can be used easily by carrying it into a room other than the video conference room, has an object of enabling the display of the input picture to be switched freely even if the picture of the line drawing is displayed together with the input picture. The picture of a line drawing, etc., is held at the corresponding position even in cases where the display of the input picture is switched by updating the input picture data, which is stored in the input picture memory 40, on the basis of the line drawing date and by writing the picture expressed with the line drawing data directly in the input picture, which is stored in the input picture memory 40.

    摘要: According to this invention, there are provided a plurality of memories in which predetermined data are written and a plurality of gates. Parity check bits are grouped into a plurality of groups in response to the bit number of the addresses of the memories. Of the grouped parity checkbits, the parity checkbits corresponding to the addresses of the memories are supplied to the addresses and the outputs of the memories are supplied to the gates so as to decode the parity check bits, whereby a threshold value is identified on the basis of the outputs of the gates.
