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.

In a network connecting a plurality of devices, the image processing function of each device, information for specifying each device, and the like are collected and controlled, and functions realizable by combining two or more devices are determined. Profiles indicating respective combinations are transferred to each device. Each device which has received the profiles displays executable functions based on the profiles, and performs control, such as the operation of the device, transfer of data, and the like, in order to realize a function selected from among the displayed functions.

Each of input and output devices previously forms device profile, and a host computer acquires virtual input/output device information including a pair of ideal input and output devices on the basis of the device profiles of these devices. If the virtual input/output device information is acquired, the input device demands to acquire a transfer path profile included in the virtual input/output device information, and then demands if the transfer path profile is acquired the output device registered in the acquired transfer path profile to connect a line. If the line connection is established, the input device performs data inputting such that the acquired transfer path profile is reflected in the device setting, and then it transfers the input data to the desired output device.

A working micro-electrode with a reference electrode prepared by coating a working micro-electrode with an insulating material except a working electrode portion, forming a silver layer on the coated surface, and then changing a portion of the silver layer into silver chloride which is the reference electrode; a working micro-electrode with a reference electrode and a counter electrode prepared by coating the working micro-electrode with the reference electrode with an insulating material, and then forming the counter electrode on the surface of the insulating material; and methods for preparing these composite micro-electrodes.Heretofore, even if the working electrode is thinly constituted, the merit of the micro-electrode has not been sufficiently utilized, since the reference electrode and the counter electrode have been thick. However, the present invention can solve this problem and can facilitate experiments in which the micro-electrode is necessary.Since an inexpensive material such as carbon can be used, the working electrode may be constituted so as to be disposable or can be cut off the used portion to repeatedly obtain a new electrode surface. Therefore, the working electrode of the present invention is economical.

A carbon micro-sensor electrode is disclosed which is prepared by impregnating, adsorbing or chemically modifying a pure composite carbon wire having many micropores extending to its surface and interior with a reactant such as an enzyme, a metal complex compound, an organic compound or a metabolite; and a method for preparing this carbon micro-sensor electrode is also disclosed.The above-mentioned electrode can be used for a long period of time, since the reactant is received in the many micropores. Furthermore, after used, the electrode may be cut off to expose a new electrode surface, and this new electrode surface may be coated with a material which does not impede an electrode reaction, whereby the reactant can be prevented from flowing out. Thus, the carbon micro-sensor electrode of the present invention can be repeatedly utilized.

A thermal storage unit has a thermal storage material which performs heat exchange through a fluid filled in a thermal storage body arranged within a vessel having an opening communicated to outside. The thermal storage body is a porous ceramic molding which contains the thermal storage medium.
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.
