Abstract: A fan chassis includes: a wall panel; and an upper panel that is connected to an upper end of the wall panel, and a lower panel that is connected to a lower end of the wall panel. A cross sectional shape of the upper panel and the lower panel is substantially U-shape. The wall panel includes a plurality of projections to be inserted into mounting holes of a fan. At least either one of the upper panel and the lower panel includes a through hole into which an upper end part or a lower end part of the fan is to be fitted. An inner dimension between the upper panel and the lower panel is shorter than an outer dimension of the fan in a vertical direction. The upper panel and the lower panel deform elastically in a direction in which the upper panel and the lower panel move apart from each other.

Abstract: A transmission apparatus includes a case including first, second, and third stages, each stage having one slot, each slot allowing free insertion and removal of a board; a first control board; a first communication unit connected with the first control board and performing radio communication; and a second communication unit connected with the first control board and performing communication faster than the radio communication. The first control board is mounted in the slot of the first stage. The first communication unit is mounted in the slot of the second stage, and the second stage is provided on one side of the first stage. The second communication unit is mounted in the slot of the third stage, and the third stage is provided on a side opposite to the first communication unit with respect to the first stage. The second communication unit is arranged adjacent to the first control board.

Abstract: The present invention is to provide an adapter mounting structure in which the degree of freedom of mounting an adapter is high, which has a mechanism simple and uncomplicated in the structure, in which adapter mounting and assembly work are easily performed, and which can be manufactured at low cost, an adapter mounting method, and an electronic device with the adapter mounting structure. An adapter fixation structure for fixing an adapter 6 including a sheet metal part 5 including a front support hole, and a sheet metal part 4 which is disposed in parallel with the sheet metal part 5 and has a rear support hole at a place where a penetrating shaft from the front support hole is tilted from the vertical direction with regard to the sheet metal part 5, wherein the adapter 6 is inserted from the front support hole to the rear support hole along with the penetrating shaft, and is held and fixed to the sheet metal part 5 while being tilted from the vertical direction.

Abstract: A lid or door hinge structure is provided, which can reduce the number of components and eliminate the possibility of detachment from a body portion as a result of opening or closing motion and also is durable very much. In assembling, a protuberance 4 of a lid 2 is inserted in a recess 5 of a body portion 1. A recess 6 of the body portion 1 and a thorough hole 8 of the lid 2 are pivoted by each other by an L-shaped pin 7. The L-shaped pin 7 is then accommodated in an accommodation space 11 formed in the lid 2 by turning it about a pivotal axis.
