A wet type flue-gas desulfurization apparatus, into which exhaust gas containing mercury goes, includes an upstream absorption tower, an upstream absorbent spray nozzle and a make-up water supply unit on an upstream side of a desulfurization apparatus body in a flow direction of the gas. The upstream absorption tower has a circulation tank reserving absorbent slurry. The make-up water supply unit supplies make-up water into the circulation tank to keep the chloride ion concentration of the absorbent in the circulation tank not lower than 50,000 ppm. Thus, it is possible to provide a wet type flue-gas desulfurization apparatus by which Hg can be prevented from being released again from the desulfurization apparatus, the purity of recovered gypsum can be increased and the usage of industrial water can be reduced.

A calculating rule for obtaining ophthalmic values which are necessary for making eyeglasses, such as near-point distance, far-point distance, visual range, and addition, especially by which the eyeglasses-wearer can continue his work at the objective working distance with no asthenopia based on accommodation, from other ophthalmic values such as power of the ametropia, accommodation, etc., and for obtaining the resultant prism-diopter and base-direction of the prism for correcting heterophoria. The calculating rule comprises a rectangular slide rule and a circular rotating rule: the slide rule comprising a fixed rule consisting of scale (A) and accommodation and scale (D) of near-point distance, and a slide rule consisting of scale (B) of power of the ametropia equal to addition and scale (C) of far-point distance, and the marks for indicating, on the scale (D), near-point distance and the objective working distances with no asthenopia which vary in accordance with the accommodations; the circular rotating rule comprising a fixed circular rule (E) and a rotating circular rule (F).

A die structure for use in a laminated core manufacture wherein a plurality of apertured sheets are provided with projections formed from the portion of the sheet from which the apertures are formed to define an interlocked laminated stack. The first of the sheets is provided with a through aperture with the projection being eliminated so as to define a nonprojecting surface in the first of the sheets of the stack, with the projections of each of the subsequent sheets extending into and being interlocked with the preceding sheets in the aperture thereof. The punching apparatus for providing the apertures and projections is selectively operated to define either the formed aperture and projection structure or a blanked out apertured structure. The blanked out apertured structure defines the first of the sheets of the stack. The extent of the projections from the sheets is preselected to be no greater than the thickness of the sheets so that the projection of the sheets superjacent the first lamination is received fully within the blanked out aperture thereof. The blanked out sheets may be indexed to define a skewed axis dynamoelectric structure.

A dynamoelectric machine core, method of forming the same, and apparatus for forming the same. The core includes a stacked laminated yoke assembly having an annular array of radially inwardly opening recesses, a stacked laminated tooth assembly having an annular array of annularly spaced teeth defining therebetween winding slots, a dynamoelectric winding in the slots, and cooperating interlock means on the teeth and yoke core assemblies for locking the tooth core assembly to the yoke core assembly. The laminations are blanked out from a metal sheet and interlocked in stacked association with each other by suitable interlock structure formed therein. The teeth are blanked out from the yoke lamination and are subsequently secured to the yoke laminations of the yoke core assembly after the tooth core assembly of the teeth is provided with the dynamoelectric winding. The teeth may be held by a suitable jig during the winding operation which accurately disposes the teeth to define the tooth core assembly and which is removed subsequent to the mounting of the wound tooth core assembly to the yoke core.
