In a silver halide photographic material, at least one mercapto complexing agent for silver salt is contained in at least one photographic constituting layer and at least one anion or betaine type cyanine sensitizing dye is contained in silver halide emulsion layer to improve photographic defects such as reduction of sensitivity, softening in tone, etc.
摘要:
Lithographic printing plates having high ink receptivity, suffuring no ink stains and having much improved printing endurance can be produced by silver complex diffusion transfer process from lithographic printing plate materials comprising a support having thereon at least both silver halide emulsion layer and physical development nuclei layer wherein the diffusion transfer processing is carried out in the presence of 2-mercaptobenzoic acid derivatives or, besides this 2-mercaptobenzoic acid derivatives, at least one compound selected from the group consisting of alkanolamines and cyclic imide compounds which may be contained in at least one layers of the lithographic printing plate materials and/or the diffusion transfer developing solutions.
摘要:
In production of lithographic printing plates by developing a photographic material comprising a support having thereon at least both silver halide emulsion layer and physical development nuclei layer by silver complex diffusion transfer process to form transfer silver to be used as ink-receptive portions of the lithographic printing plates, when the development is carried out in the presence of a cyclic imide compound (alone or in combination with sulfites, thiosulfates, thiocyanates or alkanolamines) as defined hereinafter, ink-receptivity of the transfer silver image portions and printing endurance of thus obtained printing plates are improved. Moreover, the non-image portions have no or substantially no stains.
摘要:
Method for making lithographic printing plates by silver salt diffusion transfer process is disclosed. That is, lithographic printing plates having excellent printing endurance are obtained by carrying out the diffusion transfer processing in the presence of a compound having the ring structure ##STR1## which may be present in at least one constitutive layer of the printing plate materials (photographic materials) used for making the printing plates or in the diffusion transfer processing solution.
摘要:
A heat exchanger includes a plurality of bent parts where a direction of slope of the heat exchanger changes from an upward direction to a downward direction or from a downward direction to an upward direction. The plurality of bent parts is provided on each of a side of an air inlet and a side of an air outlet. The heat exchanger is provided such that all of the plurality of bent parts is visible when the heat exchanger is seen from a front side of a casing. Drain pans are provided below each of the plurality of bent parts that are on the side of the air outlet.
摘要:
An apparatus is disclosed which projects light onto a retina of a viewer, to thereby allow the viewer to perceive a display object via a virtual image. The apparatus includes: an emitter emitting light; a modulator modulating the light; a display unit outputting the modulated light to the retina of the viewer through an exit of the display unit, to thereby display in an image display region an image representative of the display object in the form of a virtual image; and a controller controlling the emitter and the modulator so that the image is displayed in the image display region. The controller detects a relative motion of the viewer with respect to a position of the viewer, and performs at least one of control of a display/non-display status of the image, and control of a display position of the image, in accordance with the detected relative motion.
摘要:
An axial flow fan is provided having an airfoil shape that improves efficiency of the axial flow fan and increases the structural strength and workability/formability of the thin trailing edge portion. The axial flow fan includes a blade having a suction surface, a pressure surface, and a trailing edge surface; the suction surface has the same in shape as a predetermined airfoil including an NACA-series airfoil; a trailing edge portion on the pressure surface is different in shape from the predetermined airfoil. A feature is that the blade trailing edge portion including the trailing edge portions on the oppositely facing pressure and suction surfaces and the trailing edge, has a thickness greater than that of a trailing edge portion of the predetermined airfoil and strength equaling or exceeding a predetermined strength.

An electronic connector terminal and its method of formation comprising a terminal base material 2 formed from a thin metal plate including and a high cost metal plating layer 17, which covers the terminal base material 2. The terminal base material 2 is preferably formed by punching from the thin plate and includes an outer peripheral edge or lateral part 4 having at least one contact 6, and planer parts 5 defined by front and back surfaces of the punched-out piece. The high cost metal plating layer 17 on the planer parts 5 has a lesser thickness than the thickness of a high cost metal plating layer 17 on the lateral part 4.
