摘要:
A titanium dioxide powder which has a rutile content of 80% or more and a BET surface area of 30 m2/g or more; and a method for producing the titanium dioxide powder wherein a titanium tetrachloride gas, an oxygen gas, a hydrogen gas, and steam are reacted in a gas phase, which comprises supplying the steam in the chemically equivalent amount necessary for oxidizing all of the titanium tetrachloride gas or more. The titanium dioxide powder is suitably used as a coating material for a glass substrate and a filler. The method can be employed for arbitrarily producing a titanium dioxide powder which is composed of fine particles having a great specific surface area and also has a very high rutile content or an anatase type titanium dioxide powder having a high specific surface area.

A fuel cell which utilizes the biogenic metabolism to produce a high current density is provided. The fuel cell generates electric power in such a way that the fuel is decomposed stepwise by a plurality of enzymes and those electrons formed by oxidation are transferred to the electrode. The enzymes work such that the enzyme activity of the enzyme involved in decomposition in the early stage is smaller than the sum of the enzyme activities of the enzymes involved in decomposition in the later stage. In the case where a coenzyme is involved, the enzyme activity of the oxidase that oxidizes the coenzyme is greater than the sum of the enzyme activities of the enzymes involved in the formation of the reductant of the coenzyme, out of the enzymes involved in the stepwise decomposition of the fuel.

A vinylidene chloride copolymer film or a laminated film far more excellent in barrier properties than the conventional films provided. A vinylidene chloride copolymer film comprising 88% to 93% by weight of vinylidene chloride and 12% to 7% by weight of at least one monomer copolymerizable with vinylidene chloride and having a ratio (Q/P) of 1.5 or more, wherein Q is the integrated intensity of the peak at 2&thgr;=38° and P is the integrated intensity of the peak at 2&thgr;=15°, each as determined by the wide angle X-ray reflection method, shows excellent barrier properties. Further, a laminated film comprising a base film and a vinylidene chloride copolymer layer which comprises 88% to 93% by weight of vinylidene chloride and 12% to 7% by weight of at least one monomer copolymerizable with vinylidene chloride and which has a ratio (I/J) of 1.4 or above, wherein I and J are the peak intensity and base line intensity at 2&thgr;=38°, respectively, and a half band width of the peak at 2&thgr;=38° of 3° or below, each as determined by the wide angle X-ray reflection method, shows excellent barrier properties.
摘要:
It is an object to provide a printer apparatus, a control method of such an apparatus, and a printer system, in which a proper control can be performed in consideration of a change in network load. When a load of a transmission path is measured and a data reception from a host is interrupted, a waiting time of the data is extended in accordance with the measured load, thereby realizing the object. The set operating conditions are transmitted to the host and are also automatically set into the other printers connected to the network to which the printer is connected via the host, thereby realizing the object.
摘要:
A polyamide resin composition which comprises: (A) an aromatic polyamide resin comprising preferably a terephthalic acid component and a diamine component comprising at least one of an aliphatic diamine component and an alicyclic diamine component; (B) a fibrous reinforcement; and (C) at least one additive selected from the group consisting of a salt of the group I, II and III metals of the periodic table of a higher fatty acid salt and an acid ester, a partially saponified ester and a metal salt of an aliphatic carboxylic acid of 26-32 carbons.The resin composition is of high fluidity and mold-releasing properties as well as of high heat resistance and rigidity, so that the composition can be molded with decomposition of the resins.
摘要:
A fuel cell is provided having a structure in which a cathode and an anode face each other with an electrolyte layer therebetween. The cathode includes an electrode on which an oxygen reductase and the like are immobilized, and the electrode has pores therein, water repellency is imparted to at least part of the surface of the electrode. Water repellency is imparted by forming a water-repellent agent on the surface of the electrode. The water-repellent agent includes a water-repellent material such as carbon powder and an organic solvent such as methyl isobutyl ketone that causes phase separation with water. When the electrode has pores therein, there are provided a fuel cell that stably provides a high current value and a method for manufacturing the fuel cell.
摘要:
A thermal printer has a thermal head for performing printing on a continuously fed recording sheet. A platen roller is mounted to undergo rotation for feeding the recording sheet between the platen roller and the thermal head. A cutting member cuts the recording sheet after printing is performed thereon by the thermal head. A sheet presenter mechanism discharges the recording sheet cut by the cutting member to the exterior. The sheet presenter mechanism is mounted to undergo movement to vary a discharge direction of the recording sheet.
