Abstract: In an apparatus, a gas containing CH4 and CO2 is supplied from a first supply unit to a synthetic gas production unit which generates a synthetic gas containing CO and H2 while heating a first catalytic structure; the synthetic gas is supplied to a gas production unit which generates a lower olefin-containing gas including propylene while heating a second catalytic structure; and a detection unit detects propylene discharged from the gas production unit. The first catalytic structure includes first supports having a porous structure and a first metal fine particle that is present in first channels of the first supports. The second catalyst structure includes second supports having a porous structure and a second metal fine particle in the second supports. The second supports have a second channels, a portion of which have an average inner diameter of 0.95 nm or less.

Abstract: According to one embodiment, a stabilizer includes a jaw portion which contacts a bottom of an apparatus, a fastener to fasten the stabilizer to a lateral side of the apparatus, and a foot portion extending from the bottom of the apparatus toward far side and in obliquely downward.

Abstract: According to the embodiment, a case supporting part supports a substrate case on an apparatus housing in a manner that allows the substrate case to move between a first position and a second position. The first position is contained in a first range extending in a predetermined direction parallel to the side surface of the apparatus housing where a maintenance target is provided closer thereto and covering also the position of at least part of the maintenance target. The second position is contained in a range extending in the predetermined direction and covering the position of the maintenance target with the range being narrower than the first range. A control substrate is arranged such that, when the substrate case is at the first position, a plurality of connections are placed at positions corresponding to the positions of respective electrical components to which the control substrate is to be connected.

Abstract: A printing apparatus includes a platen glass, a read part, a print part, a sheet receiving part, an important information detection unit to detect whether important information is included in the original document read by the read part, a paper existence detection unit to detect at least one of whether the original document exists on the platen glass and whether the output sheet exists on the sheet receiving part, and a notifying part to notify misplacement of the original document or forgetting to take the output sheet if the important information detection unit detects that the important information is included in the read original document and the paper existence detection unit detects that the original document or the output sheet exists.

Abstract: According to one embodiment, a parrying structure around sheet junction including a first transporting guide that guides a sheet medium, a second transporting guide that guides the sheet medium toward the first transporting guide at a larger angle than a predetermined angle with respect to a direction where the sheet medium is guided by the first transporting guide, and a third transporting guide that guides a leading edge of the sheet medium, which is guided by the second transporting guide and moved to the first transporting guide, toward the first transporting guide.

Abstract: A system board provided with electrical components is contained in a substrate frame, a reinforcing frame is pivotally fixed to an peripheral part of the substrate frame, and an HDD is mounted on the reinforcing frame in a vibration-damping manner. With this structure, the HDD is mounted on the system board in a floating state, and a space is formed between them as an airflow passage.

Abstract: A working part of a cleaning unit is moved with a processing unit, when the processing unit is inserted into and removed from a main body. A driving part of the cleaning unit stays in the main body regardless of the movement of the processing unit.

Abstract: In black-and-white printing, a system control section rotates a revolver including a plurality of color developing devices, moves each color developing device to a non-development position relative to an image carrying body, and develops a toner image on the image carrying body using a black developing device having a default position set at a development position.

Abstract: The present invention retreats all developing units of a color developing apparatus to a retracted position where the units are not rotated around the axis of rotation to develop a Bk latent image by color toner, while a Bk image is being developed, and retracts the units to a position wherein a photoconductive drum can be located to be opposite to a predetermined color developing unit in the shortest time, when color image formation is instructed.
