A flexible flat circuit cable includes first and second flexible circuit substrates extending in an extension direction. The first flexible circuit substrate has a first surface forming a first conductor layer and an insulation layer, and the second flexible circuit substrate has a first surface forming a second conductor layer and an insulation layer. A bonding material layer is applied at a predetermined section between the first flexible circuit substrate and the second flexible circuit substrate to bond the first and second flexible circuit substrates together in such a way to maintain a predetermined spacing distance between the first and second flexible circuit substrate and forming a gapped segment at sections where no bonding material is applied. The first and second flexible circuit substrates form a cluster section within the gapped segment, which has opposite ends respectively forming first and second connected sections each of which forms a connection plug or is provided with a connector.
Abstract:
According to the present invention, on a double-sided substrate 1, a plurality of through-holes 2 connected to one wire 6 for plating as well as wiring are collectively arranged within a narrow range close to the connection portion. After a plating process, a penetrating hole 12 is formed and the connection potion is cut off. Thus, the wire 6 for plating and the collectively arranged through-holes 2 are made independent of one another so that no electric conduction occurs among the wire 6 for plating and the through-holes 2.
Abstract:
Planar illumination device comprise light-emitting illumination elements arranged on a carrier, containing an electrically conductive layer and an insulating 5 layer (LEDs). The light-emitting illumination elements are connected to current feed lines in the form of a conductor path. The light-emitting illumination elements are arranged as a succession of identical units on a continuous conductor path, in each case on the electrically insulating layer of the carrier. The current discharge from the light-emitting illumination elements is represented by a conductor discharging the current and by means of a connection to the electrically conductive layer of the carrier. The planar illumination device has any number of units extending in the longitudinal and transverse direction. Cutting zones, along which any units or groups of units can be separated off or separated out, are arranged between the units.
Abstract:
Synchronization between command and address signals commonly coupled to a plurality of memory devices to be operated in parallel and a clock signal coupled to the memory devices is achieved, while suppressing an increase in the clock wiring length. A semiconductor device has a data processing device mounted on a wiring substrate and a plurality of memory devices accessed in parallel by the data processing device. The data processing device outputs the command and address signals as a first frequency from command and address terminals, and outputs a clock signal as a second frequency from a clock terminal. The second frequency is set to multiple times of the first frequency, and an output timing equal to or earlier than a cycle starting phase of the clock signal output from the clock terminal can be selected to the command and address signals output from the command and address terminals.

The first device region comprises a plurality of serially-connected devices deposited on the carrier, and the second device region is adjacent to the first device region and comprises a plurality of serially-connected devices. The voltage potential of the plurality of the serially-connected devices in the first device region is substantially the same as that of the plurality of the serially-connected devices in the second device region whereby damage due to short circuit of the adjacent plurality of serially-connected devices is avoided.
Abstract:
An end of a first line and an end of a second line of a first write wiring pattern are arranged on both sides of a third line of a second write wiring pattern. Circular connection portions are provided at the ends of the first line and the second line. Through holes are formed in portions of a cover insulating layer above the connection portions, respectively. First connecting layers made of copper, for example, are formed to fill the through holes of the cover insulating layer. A substantially rectangular second connecting layer made of copper, for example, is formed to integrally cover upper ends of the connecting layers. This causes the first and second lines to be electrically connected to each other through the first and second connecting layers.
