Abstract: The present invention adopts a microbial preparation production method comprising: a step for mixing crushed waste gypsum with a culture medium containing microorganisms to obtain a mixed liquid; and a step for culturing the mixed liquid. The particle diameter of the crushed waste gypsum is at most 30 mm.

Abstract: Provided is a three-dimensional object producing method that includes applying an object forming liquid to powder including a base material and an organic material to form a solidified product, and removing the powder deposited on the solidified product from the solidified product using a powder removal liquid including an organic solvent. The following formulae are satisfied RED of non-forming part<1.20 and RED of forming part>0.55. The forming part is a portion of the powder to which the object forming liquid is applied and RED of the forming part is a distance between HSP of the forming part and HSP of the organic solvent. The non-forming part is a portion of the powder to which the object forming liquid is not applied and RED of the non-forming part is a distance between HSP of the non-forming part and HSP of the organic solvent.

Abstract: A carrier for forming an electrophotographic image is provided. The carrier comprises carrier particles each comprising a core particle and a coating layer. The coating layer comprises a coating resin and inorganic particles comprising chargeable particles A and conductive particles B. The amount of the inorganic particles is from 195 to 350 parts by mass with respect to 100 parts by mass of the coating resin. The carrier particles consist of small carrier particles (D1?25 ?m), medium carrier particles (25 ?m<D2?38 ?m), and large carrier particles (38 ?m<D3). A constituent element variation, that is a ratio of an amount of a constituent element of the inorganic particles contained in the coating layer of the small carrier particles to an amount of the same constituent element of the inorganic particles contained in the coating layer of the medium carrier, is from ?10.0% to 10.0%.

Abstract: A disk wheel for a motor vehicle includes an inner rim portion and a disk portion which are formed integrally with each other. An outer rim portion which is independent of the inner rim portion and disk portion is rigidly fitted on the outer circumferential surface of the disk portion. The inner and outer rim portions are different in thickness from each other, so that the inner rim portion is provided with greater rigidity without increasing the overall weight of the disk wheel.
