A slot line (1) is constituted of a slot (4) formed in a surface electrode (3) of a dielectric substrate (2) and two slot lines (1) are arranged with a gap (5) between them in such a manner that the surface electrodes (3) are separated from each other. A slot resonator (6) having an open end on the gap (5) side is provided on the forward end side of each slot line (1) and these slot resonators (6) are arranged to be coupled with each other. Furthermore, each surface electrode (3) is provided with a slot tab (8) branched from the gap (5). Consequently, leakage of high frequency signals through the gap (5) can be suppressed using the slot tab (8).

The invention relates to a control device and, for the first time, advantageously permits a number of individual partially flexible printed circuit boards (20a, 20b, ) to be arranged in a manner that makes it possible to optimally disentangle signal and current paths while simultaneously reducing the investment in expensive flexible surfaces (20) to a minimum. The invention helps in saving on flexible surfaces (20) and to design flexible component parts in order to make an optimal utilization possible and so no waste results. The individual partially flexible printed circuit boards (20a, 20b, ) are preferably laminated on an aluminum base plate (10). The edge areas (25) of the partially flexible printed circuit board (20a, 2b, ) are formed by appropriate measures whereby obtaining a reliable sealing by means of a molded seal. The invention is suited for mechatronic control units, particularly for control devices for mounting in a transmission or engine of a motor vehicle.

[PROBLEMS] To prevent mistake of fitting position and fitting direction of each substrate when a plurality of substrates is fitted in a base member. [MEANS FOR SOLVING PROBLEMS] Backlight unit X in a LCD device comprises such as a plurality of LED substrates 10 respectively mounting a plurality of LED elements 11 for illuminating each division multi-divided from the entire area of a LCD panel, and Chassis 1 as a base member in which LED substrates 10 are aligned and fitted, wherein Fitting position distinguishing mark 12 indicating a designed (qualified) fitting position of a relevant LED substrate 10 in Chassis 1 is recorded on each of a plurality of LED substrates 10. Fitting position distinguishing mark 12 is the mark graphically displaying the area to be covered by a relevant LED substrate 10 in the entire Chassis 1 when the LED substrate 10 is fitted in Chassis 1 as designed. And on every LED substrate adjusted in a designed fitting direction relative to Chassis 1, Fitting position distinguishing mark 12 is recorded in an area which is nearly the same area but other than the center nor vicinity thereof in LED substrate 10.

The invention relates to a channel-shaped connection device for electrical lines, especially signal and ignition lines, of internal combustion engines. At least one support element (2) is provided for preferably pre-assembled electrical lines (3) and components (7) and can be inserted, preferably pushed into receiving elements (4) of the channel-shaped connection device (1).
摘要:
In order to provide a wired circuit board in which electrical continuity inspection can be omitted and a connection structure of the wired circuit board, in connection between a first wired circuit board 1 and a second wired circuit board 2, a first connection terminal 13 and a second connection terminal 14 are abutted against each other in the direction in which they are opposed along the respective longitudinal direction of the wired circuit boards, and are arranged in line with each other, and a solder bump 15 is provided so as to continuously extend over surfaces of the first connection terminal 13 and the second connection terminal 14. Consequently, the solder bump 15 is not interposed between opposed surfaces of the first connection terminal 13 and the second connection terminal 14, thereby allowing electrical connection by the solder bump 15 between the first connection terminal 13 and the second connection terminal 14 to be confirmed from the appearance by visual observation.
