Abstract:
A bus structure may include two or more soft buses and one or more soft separation layers. The two or more soft buses may be stacked side by side with respect to each other. The one or more soft separation layers may be sandwiched between two adjacent soft buses of the two or more soft buses.
Abstract:
A foldable information processing apparatus includes a hinge part that foldably couples two housings with each other, a crank-type structured flexible printed circuit board that passes through the hinge part and electrically connects the two housings to each other, and a protector that protects an end surface of the flexible printed circuit board from a contact with the hinge part.
Abstract:
A tunable high impedance surface device (100) includes a conductive ground plane (105) and a plurality of conductive elements (110-114) electrically connected to the conductive ground plane (105). The device (100) also includes a plurality of capacitive elements (120-124) operable to vary a predetermined electromagnetic characteristic of the apparatus and standoffs (130, 132) between the plurality of capacitive elements (120-124) and the plurality of conductive elements (110-114). In one form, laser-drilled and electrically conductive micro-vias (136, 138) extend through the standoffs (130, 132) thereby electrically connecting the plurality of capacitive elements (120-124) to a data bus (140). The capacitive elements (120-124) may be integral with a circuit board (144) that supports the plurality conductive elements (110-114). Either the capacitive elements (120-124) or the conductive elements (110-114) are mechanically flexible and selectively movable to controllably adjust the distance (142) between the capacitive and conductive elements.
Abstract:
A hybrid structure of multi-layer substrates comprises a first multi-layer substrate and a second multi-layer substrate. The first multi-layer substrate stacks up first metal layers, first dielectric layers alternately and has VIAs. A border district of a first metal layer connects with a border district of the corresponding first dielectric layer. The border districts are separated from adjacent first metal layers and adjacent first dielectric layers. The second multi-layer substrate stacks up second metal layers and second dielectric layers alternately. A border district of a second metal layer connects with a border district of the corresponding second dielectric layer. The border districts are separated from adjacent second metal layers and adjacent second dielectric layers. The VIAs are located at the border districts of the first dielectric layers and each VIA has electric conductor therein to connect one first metal layer with one second metal layer.

Abstract:
An insulating substrate (17) includes a surface conductive layer (25) fixedly laminated on a surface of the plate-like semiconductor body (21) via a surface side fixing member (24, 26). The surface side fixing member (24, 26) includes a first fixing portion (26) for fixing one part (25a) of the surface conductive layer (25) located underneath the joint portion (15) of the electrode terminal (14), and a second fixing portion (24) for fixing the other part (25b) of the surface conductive layer (25) which is not located underneath the joint portion (15), and a fixing strength exhibited by the first fixing portion (26) is smaller than that exhibited by the second fixing portion (24).
Abstract:
A flexible circuit board (20) having a substantially rigid substrate (22) and an electrical resistance heater trace (24). The substantially rigid substrate (22) has a first portion (26), a second portion (28), and a bend region (30). The bend region (30) interconnects the first portion (26) and the second portion (28). The electrical resistance heater trace (24) is formed on the bend region (30) of the substrate (22). The first portion (26) of the substrate (22) is capable of being folded relative to the second portion (28) of the substrate (22) to form at least one bend (72, 172) in the bend region (30) when an electric current is applied to the heater trace (24). There is also an electronic control unit (60, 160) that includes the flexible circuit board (20) and a method of assembling an electronic control unit (60, 160).

Abstract:
In part, and in addition to apparatus and methods presented, an expansion board to be connected/disconnected to/from its mother board easily is provided. A face of a CDC (Communication Daughter Card), which is an expansion board to be connected to the mother board of a computer system is covered by an insulating sheet. In the CDC, an edge of one end of this insulating sheet is extended so as to form a projection. A user can take this projection with fingers, thereby carrying and connecting/disconnecting the CDC to/from the mother board easily.
