Abstract: A drum cartridge is configured to be detachably mounted on an apparatus main body in a state where a toner cartridge is mounted on the drum cartridge. A first shutter and a second shutter are configured such that: when the drum cartridge is mounted onto the apparatus main body in a state where the toner cartridge is mounted on the drum cartridge, the first shutter moves from a first closed position to a first open position and the second shutter moves from a second closed position to a second open position, and when the drum cartridge is detached from the apparatus main body in a state where the toner cartridge is mounted on the drum cartridge, the first shutter moves from the first open position to the first closed position and the second shutter moves from the second open position to the second closed position.

Abstract: An information transaction device is connected to an information holding device including a storage unit storing personal information and includes a sharing approval reception unit configured to receive approval of sharing of the personal information by an information sharing destination device from a user associated with the personal information, a provision approval reception unit configured to receive approval of provision which is transmission of the personal information to an information provision destination device, from the user associated with the personal information, a sharing instruction unit configured to, in a case where the sharing approval reception unit receives the approval of the sharing, instruct the information holding device to perform the sharing, and a provision instruction unit configured to, in a case where the provision approval reception unit receives the approval of the provision, instruct the information holding device to perform the provision.

Abstract: An information transaction device stores catalog information including detailed information related to one or more datasets including personal information providable to an information provision destination device from an information provision source device. The information transaction device receives a provision request for the dataset from the information provision destination device. The information transaction device outputs a transmission request for the dataset indicated by the provision request to the information provision source device.

Abstract: In foam molding for molding a foam-molded article from a foaming material, heat is applied while controlling the amount of foaming of the foaming material, control of the amount of foaming of the foaming material is halted, heating of the foaming material is removed and the foaming material is molded into a desired shape. The foaming material can be molded into a prescribed shape and at high speed even if the molded article is a complicated one.

Abstract: A twist-forming process and a coining process for a crank shaft are carried out by using one twist-forming press including a twist forming section and a coining section, and a stopper height adjusting means for determining the crank pin arrangement and for finely adjusting the twist angles is integrally incorporated into the twist-forming press.

Abstract: A thermoplastic resin having excellent impact resistance and heat resistance obtainable by polymerizing 93 to 30 parts by weight of a monomer mixture comprising 20 to 90% by weight of at least one .alpha.-alkylaromatic vinyl monomer, 10 to 40% by weight of at least one vinyl cyanide monomer and 0 to 60% by weight of at least one vinyl monomer copolymerizable therewith (100% by weight in total) in the presence of 7 to 70 parts by weight (in terms of solid) of a rubber latex of a large particle size having a particle diameter of at least 0.2 .mu.m obtained by adding 0.

Abstract: A thermoplastic resin composition having excellent impact resistance and heat resistance which comprises 5 to 95% by weight of a graft copolymer (I) obtained by polymerizing 93 to 30 parts by weight of a monomer or a monomer mixture for grafting comprising 30 to 100% by weight of at least one monomer selected from the group consisting of styrene, .alpha.-methylstyrene, acrylonitrile and methyl methacrylate and 0 to 70% by weight of at least one copolymerizable monomer having CH.sub.2 .dbd.C< group in the presence of 7 to 70 parts by weight (in terms of solid) of a rubber latex of agglomerated particles having a particle diameter of at least 0.2 .mu.m obtained by adding 0.

Abstract: In a process comprising adding an ethylenic monomer or monomer mixture (B) to a rubbery polymer (A) latex, emulsion-polymerizing it to produce a graft copolymer (C) latex, then adding an acidic substance or an electrolyte to said graft copolymer (C) latex to partially coagulate the latex, thereafter either first adding an ethylenic monomer or monomer mixture (D) and then adding a suspension polymerization stabilizer or simultaneously adding an ethylenic monomer or monomer mixture (D) and a suspension polymerization stabilizer, and carrying out suspension polymerization to obtain a graft copolymer (E) in the form of beads, a process for producing an impact-resistant resin wherein:(1) said rubbery polymer (A) contains at least 60% by weight of a diene monomer component and has a degree of swelling of 10-35, a gel content of 70% by weight or more and a weight average particle diameter of 0.2-0.5.mu. and the major part of the particles has a particle diameter ranging from 0.03.mu. to 1.0.mu.
