An image forming apparatus includes an image forming unit that forms an image on a transfer medium on the basis of image data, a feeder that feeds the transfer medium, and a control unit that manages image data and controls the image forming unit and the feeder. In a case where a base image and an overprint image are printed by the same image forming apparatus, the control unit can manage first image data of the base image and second image data of the overprint image by associating the data with each other, and when a jam of the transfer medium is detected during output of an overprint image, the control unit causes a transfer medium to which the base image is output by the image forming apparatus to be replenished for print instead of a jammed transfer medium removed by jam processing.

Image forming apparatus, image forming method, and image forming management apparatus

There are included an image forming unit for forming an image on continuous paper, a continuous paper conveying unit for conveying the continuous paper, and a control unit for controlling the image forming unit and the continuous paper conveying unit, wherein, after conveyance is started by the continuous paper conveying unit in printing preparation and before printing is started, the control unit is enabled to perform meandering prevention approach control of stabilizing conveyance of continuous paper that is being conveyed, and allows switching between performance and non-performance of the meandering prevention approach control and/or changing a level of the meandering prevention approach.

The present invention relates to a method of removing water and a free acids content in an electrolytic solution for a lithium battery, and to an electrolytic solution for a lithium battery having a low water content and acids content. The present method is characterized by comprising steps of (a) leading an inert gas through the solvent having a water content of 100 ppm or lower under heating of the solvent to vaporize water together with the solvent to thereby reduce the water content of the solvent, and (b) dissolving the lithium electrolyte in the solvent while maintaining a temperature of the solvent at 20&deg; C. or lower. The present method can make the water content at most 3 ppm and the free acids content less than 1 ppm.

A novel compound 5-(2,4-dioxotetrahydro-3-furanylmethyl)norbornane-2,3-dicarboxylic acid anhydride has been provided. The compound is prepared by hydrogenating 5-(2,4-dioxotetrahydro-3-furanylmethyl)-5-norbornene-2,3-di-carboxylic acid anhydride. The compound may be used as a hardening agent for epoxy resins, a raw material of producing polyimides, polyamides and polyesters, and a raw material for a plasticizer for vinyl chloride polymers.

5-(2,4-Dioxotetrahydro-3-furanylmethyl)norbornane-2,3-dicarboxylic acid

Methylnorbornene dicarboxylic anhydride is produced from a C.sub.6 -C.sub.7 fraction containing 5-methylcyclopentadiene by carrying out the reaction in the presence of a maleic anhydride and a protonic acid at a temperature of 0.degree.-50.degree.C., whereby the 5-methylcyclopentadiene is isomerized to 1-MCPD and 2-MCPD which undergo a Diels-Alder reaction to form methylnorbornene dicarboxylic anhydride.

Tertiary alcohols are produced by the hydration of an isoolefin in the presence as catalyst of an acidic cation exchange resin such as a sulfonated styrene-divinylbenzene copolymer, and a polyhydric neo-type alcohol such as neopentyl glycol. The process is useful for separating isobutylene from a hydrocarbon mixture containing its isomers via preparation of the alcohol, separation from the unreacted hydrocarbons and dehydration of the tertiary butyl alcohol to isobutylene.

A method of stabilizing a catalyst for the conversion of aromatic hydrocarbons in the presence of hydrogen such as the isomerization of C.sub.8 aromatic hydrocarbons to increase the content of p-xylene, is carried out by contacting a catalyst in advance of start-up with hydrocarbons in the liquid phase at a temperature preferably of about 50.degree. to about 250.degree. C. and preferably at elevated pressure up to about 50 Kg/cm.sup.2 in the absence of hydrogen; the catalyst being prepared by the acid leaching of a hydrogen form mordenite to produce a mordenite having a silica to alumina molar ratio of about 15 to 21. Preferably, the hydrocarbons used for the contacting have the composition of the feed to be converted.

A C.sub.8 aromatic hydrocarbon mixture which typically may consist essentially of xylenes and ethylbenzene, the latter being present in an amount of not more than 40 weight percent, is converted to a product containing an increased proportion of p-xylene by bringing it into contact with an acid leached hydrogen form mordenite having a silica to alumina mole ratio of 15-21 at a temperature in the range of 180.degree. to 250.degree. C. under a pressure of atmospheric to 200 Kg/cm.sup.2. Hydrogen may be present in the system in a mole ratio of hydrogen to C.sub.8 aromatic hydrocarbon mixture of 0-10. The reaction may be conducted in the vapor phase or in the liquid phase.
