Abstract: To reduce a chance that the driver overlooks the object that should be seen, a visual guidance device for guiding a visual line of a driver of the vehicle to an object existing ahead of the vehicle includes an object recognition unit for recognizing the object, and a display control unit for causing the display device to display the visual guidance virtual image for guiding the driver's visual line to a position corresponding to the object recognized by the object recognition unit on a windshield of the vehicle. The display control unit sets a length of the visual guidance virtual image to be displayed by the display device in the vehicle width direction to a length in accordance with a status of the object existing ahead of the vehicle.

Abstract: An alert system includes a display device, a display control unit, and a target recognition unit. The display control unit: when the number of targets recognized by the target recognition unit is equal to or more than an upper limit number, sets a display range of a surrounding icon as a whole circular area; and in a state where the number of targets is equal to or more than the upper limit number and the display range of the surrounding icon is set as the whole circular area, when the number of targets increases, reduces the size of the surrounding icon.

Abstract: 4,4'-Diamino-1,1'-dianthraquinonyl compounds which are obtained in a known manner and which are easy to agglomerate or aggregate owing mainly to their too fine particle size are conditioned by heating an aqueous suspension consisting essentially of the 4,4'-diamino-1,1'-dianthraquinonyl compound and water in the presence or absence of a mineral acid or an alkali. The thus obtained 4,4'-diamino-1,1'-dianthraquinonyl pigments are used in paints, printing inks, coloring of plastics and the like. The aqueous suspension is preferably prepared by desulfonating a 4,4'-diamino-1,1'-dianthraquinonyl-3,3'-disulfonic acid compound in a mineral acid such as sulfuric acid and then mixing the desulfonation reaction mixture with water or by once isolating the resulting 4,4'-diamino-1,1'-dianthraquinonyl compound and mixing the isolated compound with water.

Abstract: Crude 4,4'-diamino-l,l'-dianthraquinonyl-3,3'-disulfonic acids or salts thereof are purified by subjecting an aqueous solution containing the crude products to salting-out using inorganic salts, the aqueous solution being adjusted within a range of from acid to neutral region, whereby a product usable as such for the production of 4,4'-diamino-1,1'-dianthraquinonyl red pigments having excellent pigmentary properties is obtained in high yields with industrial advantages.

Abstract: A desulfonation reaction mixture of 4,4'-diamino-1,1'-dianthraquinonyl-3,3'-disulfonic acid obtainable in a conventional manner is mixed in the form of an aqueous acid suspension with a surface active agent, followed by filtration, whereby filterability and flowability of the produced 4,4'-diamino-1,1'-dianthraquinonyl pigment are efficiently improved.

Abstract: A suspension type transporter suspends a bolt drawing machine through a trolley and a hoist above a pressure container having many bolt attached thereto and transports the bolt drawing machine to a target position. A track settling portion having a guide is provided on an outer periphery of a lid of the pressure container. The suspension type transporter for the bolt drawing machine comprises a guide mechanism which restricts movement of the bolt drawing machine in the air by the guide. The guide mechanism of the transporter is provided with a position detector which can detect a position of the bolt drawing machine. A positioning controller of the suspension type transporter controls the transporter so that the transporter starts at slow speed, is then accelerated to a prescribed speed and is gradually decelerated near the target position.

Abstract: Copper phthalocyanine pigment which is a coloring material for ink or paint is prepared by allowing, for example, phthalate, urea, and cuprous chloride to react in a hydrophilic solvent in the presence of a catalyst and at least one element selected from the group consisting of aliphatic tetracarboxylic acids, benzophenone 3,3',4,4'-tetracarboxylic acid or anhydride thereof, pyromellitic acid or anhydride thereof, copper phthalocyanine sulfonic acids, copper phthalocyanine carbonyl imide, tetrahydrophthalic acid or derivative thereof, pyromellitic imide or derivative thereof, sulfophthalic acid, derivative thereof or the salt thereof and benzene carboxylic acid.
