摘要:
An interstage casing made of sheet metal includes a cylindrical receptacle-like body having a casing end wall on an end thereof and an open end opposite to The end. The omen end has an axial end surface and a radially inner surface which serve as a member of a spigot joint to be joined to the next interstage casing. The cylindrical receptacle-like body also includes a cylindrical side wall, a cylindrical portion joined between the casing end wall and the cylindrical side wall and having an outside diameter slightly smaller than an inside diameter of the open end, and a flat portion joined to the recessed portion and serving as an end surface of the casing end wall. The flat portion is adapted to be engageable with the end surface of the open end of an adjacent interstage casing. The flat portion has an outside diameter slightly larger than an outside diameter of the open end. The interstage casing further includes a recessed portion joined to The cylindrical portion and smaller in diameter than the cylindrical portion. The recessed portion provides a space for installing an O-ring therein.

摘要:
A strain detector in which a pair of magnetic layer patterns (5, 6) made of a magnetically permeable soft magnetic material are attached to a driven shaft (1) and a pair of detection coils (8, 9) are disposed to surround the respective magnetic layers for detecting a change in magnetic permeability of the magnetic layers which is caused when an external force is applied to the driven shaft. A magnetic yoke (15 or 16) is disposed around each of the detection coils (8 or 9) for promoting the passage of the magnetic flux therethrough, thereby decreasing flux leakage. The magnetic yokes (15, 16) each comprises an axially extending tubular member (15a) and radially inward outer and inner flanges (15d, 15e) extending from axially outer and inner ends of the tubular member, respectively. The magnetic yokes each may be made of a compacted core material containing magnetic powder and binder or assembled from a plurality of parts. A highly electrically-conductive, non-magnetic material (23) may be disposed directly between the inner ends (21b ) of the tubular member (21a) of the magnetic yokes (21) and the detection coils (8, 9) for magnetically isolating them without the need for any inner flange while allowing a compact structure.
摘要:
A silver halide photographic material and a photographic development method are described, wherein the development method is carried out using a processing liquid containing a dialdehyde series hardening agent, and the photographic material comprises a support having thereon at least a silver halide emulsion layer containing silver halide grains having a silver iodide content higher than 1.5 mole %, with the silver iodide distribution in the silver halide grains being homogeneous throughout the grains or the silver iodide content being higher in the internal portion than in the surface portion of the silver halide grains.
摘要:
A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support base having thereon a silver halide emulsion layer and a protective layer. The material contains a photosensitive silver halide emulsion and inside fogged silver halide emulsion as well as a disulfide compound. The disulfide compound is a compound represented by the general formula (I):A--S--S--B (I)wherein A and B independently represent an alkyl group, an aralkyl group, an aryl group, a heterocyclic group or ##STR1## wherein R represents an alkyl group, an aryl group, an aralkyl group, a heterocyclic group or an amino group. The material can form images having high contrast and a high maximum density. Further, the material has high sensitivity to light and can be developed at a low temperature in a reduced amount of time.
摘要:
A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support base having positioned thereon a silver halide emulsion layer and a protective layer. The silver halide emulsion layer includes at least two component layers including an upper layer and a lower layer. The upper layer is comprised of a photosensitive silver halide emulsion and the lower layer is comprised of a photosensitive silver halide emulsion and an inside fogged silver halide emulsion. The particle size of the inside fogged silver halide emulsion is smaller than that of the photosensitive silver halide emulsion in the upper layer and the lower layer. The material is highly sensitive and forms images which have high contrast and high density. The material is capable of forming images having a pure black tone. When the materials are processed they create substantially no stain even if a stopping bath is not utilized.
摘要:
A sealing device has a single rubber seal member provided with two oppositely directed seal lips which form a V-shaped cross-section and which are in contact with a spherical surface. Grease is filled in the V-shaped space. A portion of an outer fitting member protrudes inwardly to hold the seal member in place.

Anti-reflection film for a synthetic resin base comprises a first layer of silicon dioxide (SiO.sub.2) deposited on the synthetic resin base by evaporation, a second layer of alumina (Al.sub.2 O.sub.3) deposited on the first layer by evaporation, and a third layer of silicon dioxide (SiO.sub.2) or magnesium fluoride (MgF.sub.2) deposited on the second layer by evaporation. The first layer has a geometrical film thickness of 1 to 5 .mu., the second layer has an optical film thickness of .lambda./4, and the third layer has an optical film thickness of .lambda./4.
摘要:
A method for continuously producing a non-woven web having uniform distribution of filaments from natural or synthetic fibers comprising drafting with use of a high speed air-jet type drafting device a number of filaments which are fed from a filament source and blasting the drafted filaments onto a face of a moving collector, which is characterized in that the distribution of the filaments is controlled by passing the filaments through a filament distribution-controlling device comprising a filament guide passage having a narrow rectangular cross section and an air sucking means provided at least an one rectangular side wall of the filament guide passage, said controlling of the distribution of the filaments being performed with the air stream sucked spontaneously or positively from the air sucking means.
摘要:
A metal tube covered with a flexible and porous heat insulator is immersed in a processing liquid comprising a silica-containing salt and water followed by drying. The insulator is stiffened and clings to the tube, so that strength, durability and heat resistance is improved, and clamping is facilitated.
