Abstract: When performing authenticated printing, an administrator must minutely grasp the consistency between account registered information held by a printer and account information input by each user, and this complicates an updating work. In addition, the user cannot perform printing if this updating work is not performed. In an embodiment of the present invention, therefore, the administrator sets a secondary identifier group updatable by a user, and the account registered information is automatically updated based on the account information input by the user.

Abstract: In a case where a first identifier that is communicated between the printing apparatus and the information processing apparatus to specify a type of a printing medium that is used in the printing apparatus, and a second identifier unique to each of a plurality of types of printing media are set in both the printing apparatus and the information processing apparatus, the second identifier set in each of the information processing apparatus and the printing apparatus is obtained. Based on the second identifier set in each of the information processing apparatus and the printing apparatus, the first identifier set in each of the information processing apparatus and the printing apparatus is determined, such that the types of printing medium corresponding to the first identifier set in the information processing apparatus and the printing apparatus match, and a different first identifier is set regarding a printing medium of a different type.

Abstract: A fibrous anhydrous magnesium oxysulfate having a rational formula of MgSO.sub.4.5Mg(OH).sub.2 has an excellent oil absorptivity and appropriate hygroscopicity. The fibrous anhydrous magnesium oxysulfate is prepared by a process comprising cooling and diluting, with water or an aqueous solution of magnesium sulfate, a slurry of magnesium oxysulfate having a rational formula of 2MgSO.sub.4.Mg(OH).sub.2.3H.sub.2 O, obtained by dispersing magnesium hydroxide or magnesium oxide into an aqueous solution of magnesium sulfate, and then subjecting the dispersion to hydrothermal reaction, to thereby decompose the 2MgSO.sub.4.Mg(OH).sub.2.3H.sub.2 O and produce fibrous magnesium oxysulfate having a rational formula of MgSO.sub.4.5Mg(OH).sub.2.8H.sub.2), and then heat-treating the fibrous magnesium oxysulfate having the rational formula of MgSO.sub.4.5Mg(OH).sub.2.8H.sub.2 O.

Abstract: A durable structure can be easily and safely demolished by using a demolition-facilitating agent comprising, as an effective principal component 50% to 100% by weight of quick lime particles having an apparent density of 2.0 or more, a weight per unit volume of 1.0 kg/l or more, a particle size of 15 mm or less, and an average particle size of 0.1 mm or more, and optionally, additional solid particles, for example, sand particles, which are inert to water, rigid, porous inorganic grains, for example, hydrated zeolite grains, or a water-absorbing organic material, for example, acrylonitrile-grafted starch in a manner such that the demolition-facilitating agent in the dry state is fed into holes formed in a durable structure to be demolished and then water is fed into the holes to allow the quick lime particles to react with water and thus expand, to demolish the durable structure.
