Abstract: An electric noise absorber, comprising hollow cases that are shaped so as to surround the periphery of electric cable of an electronic device and are filled with a magnetic substance, such as grain ferrite, which absorbs electric noise on the electric cable. The hollow cases are molded to fit the electric cable and the quantity of magnetic substance is adjusted to reduce as much electric noise as desired. Consequently, the electric noise absorber is made easily and has no extra units.

Abstract: A substrate support of integral construction, by which substrate (20, 39) can be fixed angularly to a plate (22, 40) and which comprising a base (3, 33), a fixing portion (1, 31) for coupling the base (3, 33), a first projection (7, 37) extending from the base (3, 33), and a second projection (8, 38) extending from a wall (9) extending from the base (3, 33). The substrate (20) is gripped by the base (3, 33), the first projection (7, 37) and the second projection (8, 38) so that the end of the substrate (20) can be inserted into the space between the first projection (7, 37) and the second projection (8, 38) and the substrate (20) can be fixed angularly to the plate (22, 40).

Abstract: A device for spacing boards, like printed circuit boards, or a board and a mounting surface, like an electronic device chassis, a fixed distance apart. The device is constructed to interlock with other such devices so that boards mounted with these devices may be stacked. A peg-and-notch coupling provides horizontal stability, while a bottom anchor and top latch secure the lower and upper boards, respectively, providing stable vertical stacking.
