Abstract: PURPOSE:To improve arc resistant property while keeping thermal impact resistant property at the time of shutting large current by constructing an insulated nozzle using a material prepared by impregnating tetrafluoroethylene resin with an inorganic filler agent to have a specified thermal shock destruction resistance coefficient. CONSTITUTION:An insulated nozzle 10 of a puffer type gas-blast circuit-breaker is composed of a material prepared by impregnated tetrafluoroethylene resin with an inorganic filler agent, e.g. boron nitride 12.

Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To simplify a mass registration work and attain a mass of desired ion seed in a precise manner by a method wherein a magnetic flux density is calculated when a beam of ion seed is detected by a mass analyzer and a relation between a magnetic flux density and the mass of ion seed is utilized. SOLUTION: In a mass analyzer of an ion inplanting device, as regard to optional tow ion seeds, magnetic flux density is measured when a beam of ion seed is detected. The mass (m) of the ion seed and a magnetic flux density B as a result of measurement are substituted for a reduction formula (m=αB<c> +β) expressing a relation of both elements. In the equation, a multiplier c=2.07 is defined and unknown parameters α, β are calculated in advance in reference to an actual measured value of optional ion seed. Then, the mass (m) of ion corresponding to the generated magnetic flux density is calculated in reference to this reduction formula. Accordingly, it is satisfactory that two ion seeds are registered in a mass table, its registration work can be simplified and so it is possible to calculate a desired mass (m) of ion seed in a high precision.

Abstract: PURPOSE:To correct the non-linearity of a track and the scan by making a pair of magnetic heads scan on loci overlapping with each other in the track width direction in a normal reproduction mode and then editing the signals received from those heads. CONSTITUTION:A tape 4 is fed toward an arrow with revolutions of a rotary drum 1.
