An anatase-type titanium oxide powder having a ratio of rutile to anatase of 10% or less and a BET specific surface area of 20 to 80 m2/g. Since the titanium oxide powder has a large specific surface area and a low ratio of rutile to anatase in comparison with a conventional titanium oxide powder and excels in dispersibility, the titanium oxide powder is suitable for various applications.

A porous electroconductive material is provided. The electroconductive material enables efficient enzymatic metabolic reactions on electrodes and yields electrodes having immobilized enzymes thereon which remain stable in any working environment. The porous electroconductive material, which has a three-dimensional network structure, is formed from a skeleton of porous material and a carbonaceous material covering the surface of the skeleton. The porous material constituting the skeleton is foamed metal or alloy. This porous electroconductive material is made into an electrode, and enzymes are immobilized on this electrode. The resulting electrode with immobilized enzymes thereon is used as the anode of a bio-fuel cell.

摘要:
A mechanism that attains high-speed processing by distributing a great deal of processing to a plurality of devices upon processing does not perform processing distribution which considers hardware resources of devices used in distributed processing. When rendering processing of a print job is executed by distributed processing using devices connected to a computer network, it is determined whether hardware or software rendering processing is executed (S1102, S1103). Image processing devices which can implement hardware or software rendering processing are sought from devices connected to the computer network (S1104, S1106). Based on the determination and seek results, devices to which jobs divided from the print job are transmitted are notified (S1108).

摘要:
A dynamic behavior estimate system of an automotive vehicle includes a parameter reading unit which reads an input signal indicative of one of vehicle behavior parameters when the vehicle operates in a curved path. A discriminating unit outputs a detection signal indicative of discrimination of an instability of the vehicle when an inference value from the above one of the vehicle behavior parameters exceeds a reference value. A slip angle detecting unit detects a maximum slip angle that can hold a lateral force of front or rear wheels of the vehicle below a critical value, and sets the reference value equal to the maximum slip angle. An inference value setting unit determines an inference value from the above one of the vehicle behavior parameters, and sets the value, used by the discriminating unit, equal to the inference value, thereby allowing the discriminating unit to detect whether the inference value exceeds the reference value.
