摘要:
A valve block and a valve block unit which allow simplification and miniaturization of a pipe arrangement. The valve block includes at least one flow switching valve including a valve body, the valve selectively switching between conductions of a fluid (heat medium), a first pipe (heating outward-flow main pipe) and a second pipe (cooling outward-flow main pipe), switched by the flow switching valve, allowing the fluid to be conveyed therethrough, and a third pipe (first branch pipe) that selectively communicates with the first pipe or the second pipe, the flow switching valve, the first pipe, the second pipe, and the third pipe being connected to each other.

A film feeder/winder is capable of winding films compactly, feeding films backward and keeping films damage-free. A plurality of films wound in a magazine case are fed one by one into a film guide. The film guide is partially openable, so that a film being fed backward can be looped by protruding from the film guide. Films are fed into a scanner/exposure unit for scanning and printing. After printing, films are fed into another magazine case and wound into a roll. It is possible to print any additional films by inserting them into an inlet opening of an extra passage branching from the film feed path. Also, a film being fed backward may be guided into this extra passage until it protrudes from the inlet opening. Both magazine cases have guides and rollers for smoothly winding films around their respective film take-up cores.

A halogen lamp includes a pair of lead members, a filament bonded to and between the pair of lead members and a glass bulb encasing and sealing the filament and at least portions of the pair of lead members. The lamp further includes a support member made of non-conductive material and adapted for fixedly interconnecting legs of the pair of lead members, with the support member being disposed within the glass bulb. The lead members and the filament are bonded together by plasma welding.

An image reading device for photographic printing comprising an optical lens mechanism, a monochrome CCD image device arranged at a focal position on an optical axis of the optical lens mechanism, a filter rotation plate having a plurality of color filters rotatably arranged on the optical axis, and a cut filter for blocking unnecessary light arranged on the optical axis, wherein a light quantity correction means for obtaining stepwise spectral characteristics is arranged on the optical axis. The reflected light due to the conventional ND coating and the influences of the boundary plane and the parallel degree between the cut filter and the color filter are disappeared, whereby the occurrence of flare, ghost and color divergence can be prevented.
摘要:
A control strip holder having a light interrupting door opened and closed by the instruction of an external open-and-close instruction means is installed on the exposure table of an automatic printing and developing machine, which is provided with the open-and-close instruction means. The control strip is automatically drawn out from the holder, held onto the exposure table by air-suction and transferred to the developing unit. The control strip is drawn out by the holding force of the exposure table. As a structure for concentrating the holding force on the driving of the control strip, a mask plate is provided on the control strip holder to cover almost all the holding zone of the exposure table. The leading end of the control strip remaining outside the control strip holder is held on the exposure table by a force which is stronger than exerted on normal paper. Thus, the control strip is transferred to the developing unit through the outlet by the paper conveying belt of the exposure table.
