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.

The apparatus includes circuits for detecting sequential carrier phases of a complex baseband signal and storing the detected carrier phases. A phase predictor is responsive to the detected carrier phases for producing a predicted carrier phase. A circuit is also provided for compensating for a carrier phase deviation of the complex baseband signal in response to the predicted phase. An error detector detects an error associated with data discriminated from the complex baseband signal and a controller controls the phase predictor to minimize the error.

A wheelchair is disclosed in which a body support frame pivoted to a main frame can move from a seated posture to a stand-up posture and vice versa without using an external elevating force. The wheelchair includes the main frame for supporting driving wheels and auxiliary wheels and a body support frame formed by interconnecting a lower limb support member, a waist support member and a back rest member to one another. The forward portion of the main frame and the tip portion of the waist support member are turnably supported by a pivot, and an extension member for turnably supporting the waist support member with the pivot as the support point is interposed between the main frame and the waist support member. The motive force for the stand-up operation of the body support frame relies upon the push-up force of the user of the wheelchair (the body lift-up force of the user by his or her upper limbs) and the force of the extension member.

A negative electrode active material for an electric device includes an alloy containing silicon in a range from 27% by mass to 100% by mass exclusive, aluminum in a range from 0% by mass to 73% by mass exclusive, niobium in a range from 0% by mass to 58% by mass exclusive, and inevitable impurities as a residue. The negative electrode active material can be obtained with a multi DC magnetron sputtering apparatus by use of, for example, silicon, aluminum and niobium as targets. An electric device using the negative electrode active material can achieve a high cycle property while keeping a high discharge property.

A boiler steam amount measuring method for continuously measuring a temporal change in an amount of steam from a steam boiler, includes: first measuring a differential pressure between a pressure at a first detection position that is a predetermined position in a can body of the steam boiler or a steam outflow path, and a pressure at a second detection position in the steam outflow path separated from the first detection position toward a downstream side; first calculating a pressure loss coefficient based on the differential pressure measured by flowing a predetermined flow rate of steam or fluid instead of steam into the steam outflow path, and the predetermined flow rate; and second calculating continuously the amount of steam based on the differential pressure measured in the first measuring and the pressure loss coefficient calculated in the first calculating, and outputting the calculated amount of steam as a measurement value.
