Abstract: A method for preparing a silver halide emulsion. The method comprises supplying bromine and/or bromine ion at a plurality of processing stages to silver halide host grains to form a phase rich in silver bromide in the vicinity of the apexes of the grains. The host grains are substantially of a cube or octahedron and have a silver chloride content of about 95 mole % or more, and a silver bromide content of about 0 to about 5 mole %. The bromine and/or bromine ion is supplied at the plurality of stages by adding and mixing in a reaction vessel at least one of (i) a water soluble bromine compound, (ii) silver halide grains having a smaller average grain size and a larger silver bromide content than the silver halide host grains, and (iii) a bromine or bromine ion precursor represented by a certain formula (S). In at least one stage of the plurality of processing stages the bromine and/or bromine ion is supplied when the formation of the silver bromide-rich phase is at least 80% complete in the previous stage.

Abstract: In a forcibly cooled casting apparatus including a lower surface plate and an upper cooling plate covering the lower surface plate with a casting mold therebetween, a plurality of tube members extend through the casting mold and having a lower end supported on a receiving base of the surface plate and an upper end received in a positioning hole of the cooling plate. A sleeve provided on the cooling plate supports a protection case within which extends a cooling nozzle which passes through the cooling plate. The cooling nozzle is connected to a source of cooling fluid and has a tapered tip which fits in the upper end of the tube member so that cooling fluid can flow through the tube member. A spring compressed within the protection case biases the cooling nozzle into fluid tight contact with the tube member. A detector is provided for detecting improper positioning of the cooling nozzle.

Abstract: A lower mold made of a metal mold is disposed on a stool and an upper mold consisting of a sand mold is guided and fitted to the lower mold in such a manner as to define a cavity for a product. Tubular members are disposed at several positions in such a manner as to penetrate through the upper and lower molds and the cavity. A cooling plate equipped with cooling nozzles fitting to the projecting ends of the tubular members from the upper mold is disposed in such a manner as to clamp the upper and lower molds between it and the stool. The cooling nozzles are communicated with a cooling medium tube disposed on the cooling plate so that a cooling medium supplied to the cooling medium tube is uniformly distributed to the cooling nozzles.

Abstract: A forced cooling casting apparatus has a loop track for guiding a stool having a lower mold fitted thereto and having a punch-out portion. A plurality of stations are sequentially disposed on the loop track for effecting the steps of cleaning the lower mold, arranging an upper mold, inserting tubular members for cooling, setting a cooling plate having a plurality of cooling nozzles for passing a cooling medium through the tubular members, pouring a molten metal, effecting cooling in several stages, removing the cooling plate and taking out the resulting casting. A cooling medium tube communicates with the cooling nozzles, having a coupler and disposed on the cooling plate. A cooling medium feeder is connected to the coupler and/or a cooling medium jet device for cooling the lower mold, and is disposed at each of the cooling stations.

Abstract: An inclining molten metal charging apparatus for forced cooling casting which includes a fixed frame; an inclining frame pivotally supported by the fixed frame and reciprocatingly inclined at a predetermined angle; a stool having positioned on and fitted thereon a casting mold, a plurality chillers used for directional solidification and a tubular member internally chilled as a functional component such as a bolt fastening hole in a resulting casting; a stool support mechanism for carrying the stool into and out from a space defined by the inclining frame; a clamp mechanism for having a function of clamping the stool at a predetermined position inside the space, and equipped with a push member for pushing the casting mold to the stool when the clamp mechanism effects clamping; a molten metal vessel receiving a molten metal at the end of the forward stroke of the inclining frame and completing the charge of the molten metal into the casting mold at the end of the returning stroke; a cooling nozzle fitted to th

Abstract: An apparatus for cooling the molten metal in a mold in order to cause directional solidification. The apparatus includes a pipe extending into a mold cavity, which is defined by a space between mold pieces, with cooling fluid flowing therethrough.

Abstract: A fishing spinning reel of a type having a housing and rotatably carrying a rotary shaft having a handle, a rotor mounted on a front part of the housing and including a bail arm for retaining the fishing line for rotation with the rotary shaft, and a spool provided at the end of the rotor, includes a sleeve member having a flange formed at a front part of the housing so as to project into a recess formed in a rear part of the rotor, and a braking disc clamped by a braking member fitted to the portion of the sleeve behind the flange. A one-way engaging mechanism is interposed between the braking disc and the rotor to keep these members away from each other when the rotor is being rotated in the forward direction and to make these members engage with each other when the rotor is being rotated in the backward direction. A leaf spring provided at the rear side of the braking member is adapted to be pressed by a manipulation arm mounted on the housing and extending in the axial direction of the spool.

Abstract: A spinning reel for fishing in which a ratchet for inhibiting reverse motion of the rotor and a click gear are provided separately in a sleeve mounted with a rotor, and a holding piece designed to hold both sides of said ratchet is provided to a pawl engaged with said ratchet so that when the rotor rotation reverses, said pawl is automatically engaged with the ratchet by dint of said holding piece connected to said ratchet, and when the rotor rotates forwardly, said pawl separates from the ratchet owing to the holding connection of said holding piece to the ratchet, thus allowing engagement of the pawl and ratchet to prevent rotor reversion with no need of using any spring means therefor. Also, an elastic click pawl is provided engageably with the click gear provided separately from the ratchet, whereby it is possible to optionally select the number of teeth, material, shape, hardening treatment, etc.

Abstract: A method of culturing monogastric animals which comprises feeding the animals a feed in which part of the protein is supplied by a urea-isobutyraldehyde condensate.
