摘要:
A planographic printing plate material comprising a support and a light sensitive layer provided on the support, the light-sensitive layer being composed of (A) an inorganic material; (B) at least one metal and/or metal compound [(A)/(B) are capable of reacting with each other upon application of electromagnetic radiation] and (C) an organic compound capable of affecting the reaction between the inorganic material (A) and the metal and/or metal compound (B), wherein the inorganic material (A), the metal or metal compound (B), and the organic compound (C) are in contact with each other. When the light-sensitive layer is exposed to electromagnetic radiation, a difference in the hydrophilic or oleophilic nature of the exposed areas and the unexposed areas results, whereby a planographic printing plate is obtained which can be mounted on a printing machine and printed without any other treatments.

摘要:
A process for reducing the size of halftone dot images obtained by exposing and developing a metal image-forming material comprising a support, a thin metallic layer composed mainly of aluminum on the support and a photosensitive resin (or photoresist) layer on the thin metallic layer uniformly by first applying a solution capable of swelling the photosensitive resin layer to those parts which are to be subjected to dot size reduction, and then applying a reducer solution to the parts so treated.
摘要:
The present invention provides an axial-flow fan capable of entirely cooling an object to be cooled even when the distance between the object to be cooled and an air discharge opening of the axial-flow fan is short. A plurality of stationary blades 11A to 11E are disposed at intervals in a rotating direction of a rotor and located inside an air discharge opening 16 of an air channel 19. Each of the plurality of stationary blades 11A to 11E has an external end portion 11a connected to an inner wall portion of a fan housing 3, an internal end portion 11b connected to a peripheral wall portion 11B of a motor case 10, a discharge-side edge portion 11c formed between the external end portion 11a and the internal end portion 11b and located at a side of the air discharge opening 16, and a suction-side edge portion 11d formed between the external end portion 11a and the internal end portion 11b and located at a side of the air suction opening 14. An outer surface of the bottom wall portion 10A of the motor case 10 is located closer to a side of the air suction opening 14 than the discharge-side edges 11c of the plurality of stationary blades 11A to 11D are located.
摘要:
[Problems]To observe a state of an infant without attaching measurement instruments to an infant, thereby enabling early detection of various diseases and reducing a parent's mental burden ascribable to the observation. [Means for Solving the Problems]An imaging device 2 photographs an infant to output a motion picture of the infant as digital data, and an analyzing device 1 determines movement of at least one limb out of the four limbs of the infant from the motion picture of the infant photographed by the imaging device 2 to identify a disease and/or symptom of the infant from the movement of the limb.
