Abstract: An image forming apparatus includes an image forming section, sheet type list storage, an authentication section, a display controller, and a display section. The image forming section forms a data image on a sheet. The sheet type list storage stores user sheet type lists therein on a user-by-user basis. The user sheet type lists each include one or more sheet types extracted from among sheet types included in a sheet type list. The sheet types are sheet types that the image forming section is capable of coping with. An authentication section authenticates a user. The display controller generates a sheet type selection screen based on a user sheet type list corresponding to the user authenticated by the authentication section among the user sheet type lists stored in the sheet type list storage. The display section displays the sheet type selection screen generated by the display controller.

Abstract: A steam turbine includes an outer casing (19) that is provided with a first steam outlet port (54), through which exhaust steam flowing through the entire length of a flow path (21) defined between an inner casing main body (45) and an outer casing main body (51) in a direction along an axis (O1) is discharged to the outside of the outer casing (19), and a second steam outlet port (55), which is provided in the outer casing main body (51) and through which the exhaust steam passing through a portion of the flow path (21) or the exhaust steam not passing through the flow path (21) is discharged to the outside of the outer casing (19); a first valve (28) that adjusts opening of the first steam outlet port (54); and a second valve (32) that adjusts opening of the second steam outlet port (55).

Abstract: A steam turbine includes an inner casing which has an inner casing body in which a first main flow path to which steam is to be supplied from an inner introduction port is defined, an outer casing which has an outer casing body which defines a second main flow path between the inner casing body and the outer casing body and an upper discharge port and a lower discharge port which are in the outer casing body and through which exhaust steam is to be discharged, an upper valve and a lower valve configured to adjust a flow rate of the exhaust steam which has been discharged, and a control unit which can independently control the upper valve and the lower valve.

Abstract: The image forming apparatus includes a first control section and a second control section. The first control section includes first nonvolatile memory having a log saving area and, upon occurrence of an error, acquires an error log and saves the error log into the log saving area. The second control section includes second nonvolatile memory for storing second software therein and, upon occurrence of an internal communication error causing an interruption of communications with the first control section, the second control section erases the second software and saves in the second nonvolatile memory a communication error log necessary for analysis of the internal communication error.

Abstract: A steam turbine (1) includes an inner casing (3) which has an inner casing body (15) in which a first main flow path (11) to which steam is supplied from an inner introduction port (16) is formed, an outer casing (5) which has an outer casing body (20) which forms a second main flow path (120) between the inner casing body (15) and the outer casing body (20) and an upper discharge port (23) and a lower discharge port (24) which are provided in the outer casing body (20) and through which exhaust steam (S2) is discharged, an upper valve (7) and a lower valve (8) which adjust a flow rate of the discharged exhaust steam (S2), and a control unit (9) which can independently control the upper valve (7) and the lower valve (8).
