Abstract: The invention discloses a fumigant composition for pest control comprising a chemical compound represented by formula (I) or/and a pesticidally acceptable reagent. By administering an effective amount of the fumigant composition for pest control disclosed in the invention into a closed space is capable of effectively killing a variety of pests, and will not have a considerable health impact on human and harm to the environment; given an appropriate operation is taken.

Abstract: A computer apparatus includes a first cover, a second cover, a motherboard, an expansion device and a detach assisting assembly. The second cover is detachably disposed on the first cove, and has an accommodation space and an opening. The motherboard is disposed between the first and second covers. The expansion device disposed in the accommodation space and connected to the motherboard is drawable from the accommodation space through the opening. The detach assisting assembly disposed in the accommodation space includes a slidable member and a rotatable member. The slidable member is slidable relative to the second cover for rotating the rotatable member to drive the first pressing part to press a side of the expansion device away from the opening, and thereby at least a part of the expansion device protrudes from the accommodation space through the opening.

Abstract: The disclosure provides a fixation structure, for accommodating and fixing a storage module, including an accommodating housing. The accommodating housing includes a fixed housing and a movable housing. The fixed housing includes a bottom frame and a side frame. The side frame stands on three adjacent sides of the bottom frame to form an opening therebetween. The movable housing is detachably installed on the bottom frame to close the opening and forms an accommodation room with the fixed housing. The storage module is located in the accommodation room. The fixed housing and the movable housing are made of metal.

Abstract: A HDD tray structure is disclosed. The HDD tray structure includes a tray housing, a flexible printed circuit board (FPC) installed on the tray housing, and at least one indicator, wherein one end of the FPC has a metal pad electrically connected to a connector of a printed circuit board, and the other end of the FPC is in electrical contact with the indicator, so as to control the on/off state of the indicator.

Abstract: An automatic retractable device of a flexible printed circuit board is described. The automatic retractable device of the flexible printed circuit board comprises a bracket, two elastic components and two rollers. By combining the elastic components, the rollers and the flexible printed circuit board, the flexible printed circuit board can revert to an original position after the flexible printed circuit board is used.

Abstract: A slidable motherboard tray structure is disclosed for holding and moving a motherboard. The slidable motherboard tray structure is featured in using leverage principle to design handle elements pivotally connected to a motherboard tray housing, so that pushing force is generated between the respective handle elements and supporting elements, thereby enabling the motherboard located in the motherboard tray housing to slide to a predetermined position, thus achieving the purposed of automatically positioning and saving force.
