摘要:
A print job often includes secret information, and information may suffer sniffing from devices that execute distributed processing of jobs, or on the network. Therefore, executing the distributed processing of a print job including secret information reduces the robustness in terms of security protection. Hence, upon reception of a job, a task manager (TM) issues, to a dynamic job scheduler (DJS), a request of target devices of distributed processing according to a security level indicating the importance level of data included in that job. The DJS notifies the TM of the target devices, and the TM transmits divided jobs to the target devices.

摘要:
When data of a print job are stored on another device or a file server, data transfer is required to obtain image data, and the start of a print process and a preview process take time compared to a print job whose data is stored in a local storage device. Hence, a print job is started, and it is checked if data for all pages of the print job are locally held. If data for all pages of the print job are locally held, a print process is continued; otherwise, data for remaining pages are obtained and undergo the print process parallel to the print process for a first part.
摘要:
This invention relates to a printing system configured to output printing media having undergone print processing by a print apparatus to a plurality of destinations including a specific destination which has a structure allowing an operator to take out the printing media. In the system, output of printing media to the specific destination is restricted while the operator takes out the printing medium outputted to the specific destination, and in case that the number of printing media necessary for a job processed by the print apparatus is smaller than a predetermined number, the system is controlled not to output to the specific destination a printed material formed from printing media smaller in number than the predetermined number. This invention can achieve efficient printing by controlling not to stop the print operation of the system as much as possible.

A layout apparatus lays out a document by referencing personal information registered on a per user basis. Even if no particular print setting is input for a print job by a user, excellent prints customized for each user are thus provided.
摘要:
Following executing print processing according to a first print job, in the event of executing printing processing according to a second print job which has different sheet attributes from the first print job, a printing apparatus according to the present invention, which subjects sheets having various types of sheet attribute to printing processing, outputs a change instruction for changing the sheets loaded in a predetermined paper feed tray in response to completion of the printing processing according to the first print job.
摘要:
A vanadium electrolytic solution containing highly concentrated and dissolved vanadium is produced by a method wherein a vanadium compound selected from the group consisting of ammonium metavanadate and vanadium pentaoxide is subjected to a reduction operation in the presence of inorganic acids. At this time, by repeating the addition of the concentrated inorganic acids and the vanadium compound, a tetravalent and pentavalent vanadium solution of 3.4 mol/l is obtained.In addition, the resulting vanadium electrolytic solution is electrolyzed, whereby tetravalent vanadium is reduced to be trivalent on the negative electrode and is oxidized into pentavalent vanadium on the positive electrode, and then pentavalent vanadium is reduced into tetravalent vanadium by a reducing agent to form a discharged couple of trivalent and tetravalent vanadium, and an electrolytic solution is obtained which is capable of being charge-discharged.This electrolytic solution can be used as the electrolytic solution for redox batteries using vanadium as the active material in both positive and negative electrodes.
摘要:
Novel syntheses of dihalovinylcyclopropanecarboxylates, including potent insecticides, are described. The processes begin with the reaction between an alkenol and an orthoester to produce a .gamma.-unsaturated carboxylate, followed by the catalyzed addition of a carbon tetrahalide to the double bond and dehydrohalogenation to produce a cyclopropane derivative.
摘要:
A process of preparing 2-trifluoromethylpropanol by vapor phase contact reaction between 2-trifluoromethylpropanal trimer and hydrogen in the presence of a catalyst of which the principal component is reduced nickel. The hydrogenation reaction can easily be completed at about 30.degree.-150.degree. C. and at the atmospheric pressure. The starting material is hydrogenated nearly theoretically and with very high selectivity factor for 2-trifluoromethylpropanol.
摘要:
Crude hexafluoroacetone (HFA) containing chlorofluoroacetone(s) (CFA) as well as hydrogen halide(s) is purified by initially allowing the crude HFA to be absorbed in water to give an aqueous solution in which HFA and CFA are in the form of their respective hydrates, adding a calcium compound such as carbonate, hydroxide or oxide to the solution to neutralize the hydrogen halide(s), and decomposing the hydrated CFA by first adding an alkali metal compound such as K.sub.2 CO.sub.3 or Na.sub.2 CO.sub.3 or an alkaline earth metal compound such as Ca(OH).sub.2, Ba(OH).sub.2, CaO or BaO to the solution and subsequently adding a mineral acid such as HCl or H.sub.2 SO.sub.4 to the same solution. This procedure results in complete decomposition of CFA without causing decomposition of HFA and spontaneous separation of the liquid reaction system into two layers, one of which is exclusively HFA hydrate. Accordingly it is easy to separate pure HFA hydrate from the decomposed impurities.
