摘要:
A process for preparing a lithographic printing plate, which has excellent printability, durability and stability, which comprisingimagewise irradiating a lithographic printing plate material comprising a support having thereon a light-sensitive layer comprising, as essential components, (a) an inorganic material and (b) at least one member selected from the group consisting of a metal and a metal compound, both of which are in contact with each other and which, upon irradiation with electromagnetic radiation, react with each other forming a mutually diffused state and as a result, a difference in the hydrophilic property or in the oleophilic property occurs between the areas irradiated with the electromagnetic radiation and the non-irradiated areas, with electromagnetic radiation, andthen wetting the light-sensitive layer thereof with wetting solution containing (i) at least one compound selected from the group consisting of thiourea and a thiourea derivative and (ii) as an acid component, at least one compound selected from the group consisting of an inorganic acid, an acidic inorganic salt, and an organic acid.

An electric fan is provided, including a labyrinth structure with increased performance of preventing entry of a liquid into a receiving space to receive a stator and a rotor. A clearance is defined between an opposed wall portion of a base and an opposed wall portion of an impeller body, which are opposed to each other in an axial direction of a rotary shaft, to form a labyrinth structure. The opposed wall portion of the base and the opposed wall portions of the impeller body are shaped to form a volume expanding portion within the clearance. The volume expanding portion is constituted from a groove portion for expanding the clearance, having a volume larger than other portions within the clearance.

The present provides a heat-emitting element cooling apparatus which has a higher heat-emitting efficiency than that of conventional heat-emitting element cooling apparatus.A heat-emitting element cooling apparatus 1 includes a heat sink 7 and a fan unit 5. The heat sink 7 has a base 33 onto which a heat-emitting element is to be mounted, radiation fins of a first type 35, and radiation fins of a second type 37. The radiation fins 35 extend from an upper surface 33A in an upward direction. The radiation fins 37 extend from either of two side surfaces 33B and 33C in either of rightward and leftward directions. The radiation fins 35 and 37 continuously extend in forward and rearward directions respectively.

A travel control system for controlling a first travel vehicle which travels on a first travel course toward a junction between the first travel course and a second travel course and a second travel vehicle which travels on the second travel course toward the junction in a travel course network comprising the junction, includes counting means for counting a number of the first travel vehicle which exists in a predetermined junction area comprising the junction, and regulator means for stopping the second travel vehicle before the junction area when the counted number of the first travel vehicle is one or more. The regulator means advances the second travel vehicle into the junction area when the counted number of the first travel vehicle is zero.
