摘要:
A method for producing an aldehyde, which comprises reacting an olefin with carbon monoxide and hydrogen in a hydroformylation reaction zone in the presence of a rhodium catalyst having an organophosphorus compound as a ligand, wherein a reaction solution withdrawn from the hydroformylation reaction zone, which contains an unreacted olefin, an aldehyde product and the catalyst, is countercurrently contacted with carbon monoxide and hydrogen in a contact tower to separate and recover the unreacted olefin without substantially deactivating the rhodium catalyst and supplying the recovered unreacted olefin together with the carbon monoxide and the hydrogen to the hydroformylation reaction zone.

A machining oil applying apparatus that applies machining oil onto a thin metal plate that is being conveyed toward a press apparatus includes: an upper surface applying unit that is impregnated with machining oil, contacts an upper surface of the thin plate and applies the machining oil onto the upper surface; a lower surface applying unit that is impregnated with the machining oil, contacts an lower surface of the thin plate and applies the machining oil onto the lower surface; and an applying unit moving portion that causes the upper surface applying unit and the lower surface applying unit to move reciprocally in a direction perpendicular to a conveying direction of the thin plate, wherein the upper surface applying unit and the lower surface applying unit always move in respectively opposite directions perpendicular to the conveying direction.
摘要:
According to this invention, there is provided an image printing system which causes a plurality of image printing apparatuses to share and concurrently process an image printing job for outputting a plurality of prints based on image printing conditions and image information supplied from an information processing apparatus. In the image printing system of the invention, each of the image printing apparatuses interactively connected to each other has a proof/wait selection function of selecting a proof mode of outputting a single print or a wait mode of displaying image printing conditions and waiting. A master machine to which image printing conditions and image information are supplied from an information processing apparatus executes image printing operation in the proof mode or wait mode, and transfers the image printing conditions and image information to another image printing apparatus.
