Abstract: The mixing state of static mixing is optimized, so that it is possible to form silver halide emulsion particles in small sizes with an excellent mono-dispersion characteristic. An aqueous solution of haloid salt is blown out from a first nozzle into a mixing chamber as a rectilinear flow of turbulent flow, and before eddy viscosity formed when the rectilinear flow is blown out from the first nozzle of a small diameter to the mixing chamber of a greater diameter reaches a maximum, or before a maximum flow speed of the rectilinear flow is reduced to {fraction (1/10)} or below, an aqueous solution of silver nitrate is blown out from a second nozzle as a crossflow of turbulent flow which crosses the rectilinear flow at a substantially right angle and is entrained by the rectilinear flow, so that the two solutions are allowed to mix and react with each other instantaneously, and a liquid resulting from the mixing and reaction is discharged from a discharge duct.

Abstract: A submerged jet injection nozzle includes a nozzle exit disposed downstream of an orifice section and greater in diameter than the orifice section. The occurrence of cavitation due to a fluid injection is positively promoted so that the crushing effect of the cavitation is utilized fully and the decay in the energy of the injected fluid is reduced thereby increasing the work done by the submerged fluid injection.

Abstract: An externally ornamental golden color part such as a wrist watch case, band or bezel comprising a thermal resistance substrate and a titanium nitride coating deposited on said substrate and including in a portion of the thickness of said coating at least one member selected from the group comprising Al, Si, V, Cr, Fe, Co, Ni, Cu, Zn, Ge, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Sn, Sb, Ti, Hf, Ta, W, Ir, Pt and Au.

Abstract: An ornamental part for watches such as a watch case having a composite coating layer consisting essentially of titanium and titanium nitride, the ratio of the two components being varied in the direction of the thickness of the layer. The composite coating may be formed by the physical vapor deposition method in which the titanium in the vapor phase is reacted with nitrogen under a glow-discharge condition. The coating thus formed has a gold color and excellent physical and chemical properties.

Abstract: Relatively large hologram storage plates, e.g., those storing a large number of discrete entries such as character definitions for a large character set, comprise an array of mini-holograms arranged in different memory plate sections.A different photodiode array is associated with each hologram plate section (for efficiency, some elements of different diode arrays may be common). When the stored contents of any mini-hologram are interrogated by a coherent light beam, the stored information is derived via the associated photodiode array and converged (as by OR logic) to memory output terminals.

Abstract: A multiplexed holographic recording system employs plural transparent positive pictures, each representing a different pictorial or video information content, which embody differing, unique pre-assigned spatial frequencies. A hologram is formed of the positive pictures, the reconstructed image from the hologram being identical in smoothed intensity distribution to a composite picture formed by superposition of the positive pictures.Spatial frequency filters are employed to remove, from the object beams transmitted through the positive pictures driving hologram formation, spatial frequency components assigned to other pictures. Accordingly, crosstalk between the multiplexed pictorial information is obviated.
