摘要:
Method for subdividing the magnetic domains of a grain-oriented electrical steel sheet is improved so that the watt loss can be further lessened and the watt-loss improving effect does not disappear during stress relief annealing. An intrudable means is formed on the finishing-annealed steel sheet on or in the vicinity of strain which promotes the intrusion of an intrudable means. Sb or Sb containing material is a preferred intrudable means and the laser irradiation is a preferred method for imparting the strain and also for attaining the removal of a surface coating.
摘要:
A grain-oriented electromagnetic steel sheet has an ultra low watt loss and heat resistant subdivided magnetic domains. The electromagnetic steel sheet has spaced apart regions of plastic strain and an insulating coating disposed thereon. Intruders are thermally intruded into the spaced apart regions of plastic strain causing the subdivided magnetic domains to be heat resistant and maintaining the subdivided magnetic domains after stress relief annealing. Preferred intruders include Sb and Sb containing materials.
摘要:
The heat resistant subdivision of magnetic domains of a grain-oriented electrical steel sheet for improving the watt loss characterized by forming intruders therein is improved by pickling the steel sheet prior to the electroplating of the intrudable means. The partly exposed steel sheets are pickled by HNO.sub.3, H.sub.2 SO.sub.4 containing Fe.sup.3+, HCl containing Fe.sup.3+, and/or HBF.sub.4.

摘要:
The adhesiveness of a glass film and watt loss of a grain-oriented electrical steel sheet is improved by partially protruding the glass film into the steel sheet part thereof. To attain the partial protrusion, the steel sheet is subjected, prior or subsequent to decarburization annealing, to a treatment of the surface thereof to form unevenness, by a mechanical device, e.g., brush rolling, buff polishing, marking-off, sand papering, and grinding.

A negative electrode active material for an electric device includes an alloy containing Si in a range of greater than or equal to 27% by mass and less than 100% by mass, Sn in a range of greater than 0% by mass and less than or equal to 73% by mass, V in a range of greater than 0% by mass and less than or equal to 73% by mass, and inevitable impurities as a residue. The negative electrode active material can be obtained with, for example, a multi DC magnetron sputtering apparatus by use of Si, Sn, and V as targets. An electric device using the negative electrode active material can achieve long cycle life and ensure a high capacity and cycle durability.

摘要:
An airbag device for the body instantaneously activates an airbag without malfunctions.When an absolute value of an angular velocity detected by an angular velocity sensor exceeds a predetermined angular velocity value, angular velocity values are integrated from a most recent detected value to an oldest value within a predetermined time period, and if an absolute value of a resultant value of integral exceeds a predetermined value and an acceleration detected by an acceleration sensor is smaller than a predetermined acceleration, the airbag is inflated. Based on the value of the integral of the angular velocities, a case in which an angular velocity gradually increases is distinguished from a case in which an angular velocity momentarily increases, so the airbag device effectively prevents malfunctions caused by an action other than falling over. Additionally, because it is unnecessary to intentionally delay determination to prevent malfunctions, the airbag can instantaneously be inflated.

First, the emission amount of nitrogen oxides can be decreased close to zero as much as possible, and the emission amount of carbon monoxide is decreased to a permissible range. Second, energy saving by combustion at a low air ratio close to 1.0 is realized. Third, air ratio control is performed stably in a combustion region at a low air ratio.The present invention includes: a combustion step of burning hydrocarbon-containing fuel in the burner, thereby generating gas free of hydrocarbons but containing oxygen, nitrogen oxides, and carbon monoxide; a hazardous-substance decreasing step of bringing the gas into contact with an oxidation catalyst, thereby oxidizing carbon monoxide contained in the gas by oxygen and reducing nitrogen oxides by carbon monoxide; and a concentration ratio adjusting step of adjusting a concentration ratio of oxygen, nitrogen oxides, and carbon monoxide in gas on a primary side of the oxidation catalyst to a predetermined concentration ratio in which a concentration of nitrogen oxides on a secondary side of the oxidation catalyst is decreased to substantially zero or a value equal to or lower than a predetermined value and a concentration of carbon monoxide on the secondary side of the oxidation catalyst is also decreased to substantially zero or a value equal to or lower than a predetermined value.
