Abstract:
A toner container is removably installable in an image forming apparatus having a communication portion and a positioning hole. The toner container includes an electronic data storage device disposed on a surface of the toner container, to communicate with the communication portion in the image forming apparatus, the electronic data storage device having an engaged hole; and a positioning projection, formed in the surface of the toner container, to engage the engaged hole of the electronic data storage device and the positioning hole in the image forming apparatus. The positioning projection inserts into the positioning hole in the image forming apparatus with the positioning projection engaging the engaged hole in the electronic data storage device to determine an installation position of the toner container relative to the image forming apparatus and set the electronic data storage device relative to the communication portion in the image forming apparatus.
Abstract:
An expander-compressor unit (10) includes a two-stage rotary expansion mechanism (3) having a first cylinder (41) and a second cylinder (42). In the expansion mechanism (3), a suction port (71) facing a working chamber on the upstream side in the first cylinder (41) and a discharge port facing a working chamber on the downstream side in the second cylinder (42) are formed. An intermediate plate (43) is provided between the first cylinder (41) and the second cylinder (42). In the intermediate plate (43), a communication passage (43a) for allowing communication between a working chamber on the downstream side in the first cylinder (41) and a working chamber on the upstream side in the second cylinder (42) is formed. The communication passage (43a) does not communicate with the working chamber in the first cylinder (41) during the suction process, and communicates with the downstream working chamber in the first cylinder (41) at or after the end of the suction process.
Abstract:
An expander-compressor unit (30) includes: a closed casing (1) holding an oil at a bottom portion thereof; a motor (2) provided in the closed casing (1); a compression mechanism (3) for compressing a refrigerant and discharging it into the closed casing (1), the compression mechanism (3) being disposed below the motor (2) in the closed casing (1); an expansion mechanism (4) disposed below the compression mechanism (3) in the closed casing (1); and a coupling mechanism (50) for coupling a compression mechanism side shaft (5) to an expansion mechanism side shaft (6). An oil supply passage (53) for supplying the oil to the compression mechanism (3) is formed in the compression mechanism side shaft (5). An oil suction port (53A) is provided in a portion of the compression mechanism side shaft (5), the portion being above the expansion mechanism (4).
Abstract:
A nonaqueous electrolyte secondary battery which has a positive electrode containing lithium cobalt oxide as a positive active material, a negative electrode containing a graphite material and a nonaqueous electrolyte solution containing ethylene carbonate as a solvent and which is charged with an end-of-charge voltage of at least 4.3 V. Characteristically, the battery uses, as the positive active material, lithium cobalt oxide obtained by firing a mixture of a lithium salt, tricobalt tetraoxide (Co3O4) and a zirconium compound and having particle surfaces onto which the zirconium compound adheres.

Abstract:
A developer carrier which holds a developer on a surface and is rotatable includes: a plurality of grooves which is formed on the surface, wherein each of the grooves is wavy-lined, an inclination direction of the grooves to an axis of the developer carrier is cyclically changed in an opposite direction, and the grooves are respectively arranged at intervals.
Abstract:
An expander-compressor unit (200A) includes a closed casing (1), a compression mechanism (2), an expansion mechanism (3), a shaft (5), and an oil pump (6). The shaft (5) couples the compression mechanism (2) to the expansion mechanism (3) so that power recovered by the expansion mechanism (3) is transferred to the compression mechanism (2). The oil pump (6) is disposed between the compression mechanism (2) and the expansion mechanism (3), and supplies an oil held in an oil reservoir (25) to the compression mechanism (2). An oil supply passage (29) is formed in the shaft (5) so that the oil discharged from the oil pump (6) can be supplied to the compression mechanism (2). A lower end (29e) of the oil supply passage (29) is located below an inlet (29p) of the oil supply passage (29) formed in an outer circumferential surface of the shaft (5).
Abstract:
A rotary expander includes: a cylinder (61); a piston (62) disposed inside the cylinder (61); closing members disposed with the cylinder (61) being sandwiched therebetween; and an injection passage for introducing further a working fluid in the expansion process of the working fluid. An introduction outlet (65c) of the injection passage leading to the working chamber (69) is provided at a position located inwardly away from the inner circumferential surface (61b) of the cylinder (61), on one of the closing members, in such a manner that the injection passage and the discharge passage are not communicated with each other.
