PROBLEM TO BE SOLVED: To provide a flexible flat cable aimed at prevention of degradation of smoothness of rotating movement of a rotating shaft, prevention of degradation of flexibility of a flat cable, and prevention of degradation of durability of the flat cable. SOLUTION: The flexible flat cable with gap parts is provided with a first substrate 11, a first conductive layer, a second substrate 21, a second conductive layer, an adhesive layer 3, and a cluster part 4. The first substrate 11, extended in an extension direction, is equipped with a first surface and a second surface. The first conductive layer is formed on the first surface of the first substrate 11. The second substrate 21, equipped with a first surface and a second surface, is arranged in correspondence with a position of the first substrate 11, and the second surface of the second substrate 21 is opposed to the second surface of the first substrate 11. The second conductive layer is formed on the first surface of the second substrate 21. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
A fluid control apparatus is provided which makes it possible to effortlessly perform cable connection even when a plurality of the fluid control apparatuses are disposed adjacent to each other. The fluid control apparatus includes fluid control units to control a flow rate or pressure of a fluid, an electric circuit board to send and receive a signal to and from the fluid control units, a casing to accommodate therein the fluid control units and the electric circuit board, and an apparatus-side connector interposed between the electric circuit board and a cable electrically connected thereto. The fluid control apparatus further includes a connector board configured to mount thereon the apparatus-side connector. The connector board is secured to the electric circuit board with at least a part of the connector board in surface contact with the electric circuit board, or overlapping the electric circuit board with a clearance therebetween.
Abstract:
A method and circuit board arrangement for an intrinsically safe portable device includes two or more circuit boards having a frame structure that forms a contiguous boundary around a space between the circuit boards. In the space there are circuit components mounted on both circuit boards, and a connector that connect the two circuit boards. An encapsulant material fills the space bounded by the frame structure between the circuit boards to exclude airborne material from coming into contact with the encapsulated circuit components.
