摘要:
A process of producing modified wood by impregnating dried wood with a mixed solution composed of phthalic anhydride as a polybasic acid anhydride and epichlorohydrin as an epoxy compound at a mol ratio of 1:1 to 1:30 by dipping the wood in the mixed solution, withdrawing the impregnated wood from the mixed solution, and heating the wood to a temperature of from 60.degree. C. to 180.degree. C. to simultaneously adding phthalic anhydride and epichlorohydrin to the hydroxyl groups of the wood. By the process of this invention, excellent dimensional stability and weather resistance can be imparted to the wood while retaining the properties specific to the wood.

摘要:
This invention provides an enhancer of the effect of adrenocorticoid on nephritis without enhancement of the undesirable side-effects of the said adrenocorticoid, comprising the water-soluble gum obtained from the stem and/or branch of Acacia species, e.g., Gum Arabic. The combination of the adrenocorticoid and the said water-soluble gum enhances the effect of the said adrenocorticoid on nephritis without enhancement of the undesirable side-effects of the hormone agent.
摘要:
When a holder of an ID card approaches an image formation instructing device for sending an image forming instruction to an image forming apparatus, an ID code stored in a RF-ID element built in the ID card is read by a RF communication device. When the image formation instructing device transmits an image forming instruction to the image forming apparatus in this condition, an image forming operation is executed and the number of sheets for image formation is counted by counting means. Further, the counted number of sheets for image formation is associated with an ID code having predetermined bearing on the personal ID code read by the RF communication device and thereafter stored and held in a number-of-sheets file. Thus, the number of sheets for image formation is managed without preparing a key counter, a key card, etc. and without special operation.
