    Abstract: The signal transmission flat cable provided includes a first layer of substrate membrane, a second layer of a plurality of parallel traces for transmitting the signal, a third layer of finger array and a fourth layer of thin polyester membrane. The third layer of finger array covers the second layer. The fourth layer of thin polyester membrane is used to protect the second layer and third layer. The signal transmission flat cable is characterized in that the plurality of finger arrays are provided in the third layer at a plurality of predetermined locations along the flat cable and each of the plurality of finger arrays is spaced from each other by a given distance. A glue material is provided to bond the fourth layer and the second layer along the given distance. As a result, the flat cable has the module capability by which an user may cut away the excess portion of the flat cable depending on different requirement, such that the remaining portion of the flat cable may be inserted into the keyboard socket on the motherboard of a computer.

    Abstract: A magnetic disk device includes a flexible printed circuit board having a first portion provided with read/write ICs for read/write heads and first printed patterns connected to the read/write ICs and a second portion positioned within the first portion, an end of the second portion being connected to the first portion so as to be bendably projected from the first portion, the second portion being provided with a servo IC for the servo head and second printed patterns connected to the servo IC, the flexible printed circuit board being mounted on an actuator body such that one end of the first portion lies outside the actuator and the second portion lies on the actuator body. The magnetic disk device also includes first lead wires of the read/write heads extending to the flexible printed circuit board and being connected to the first patterns, and second lead wires of the servo head extending to the flexible printed circuit board and being connected to the second printed patterns. The first lead wires and the read/write ICs are on one side of an imaginary plane while the second wires and the servo IC are on an opposite side of the imaginary plane, the imaginary plane passing through the tip end of an arm structure and a shaft of the actuator body and being parallel to the shaft.

    Abstract: Membrane switch assembly comprises a substrate, a flexible membrane, and a separator between the substrate and the membrane. The substrate has circuit conductors thereon and has an integral tail onto which the conductors extend. The separator is a flexible film and has an integral tail insulator which extends over the surface of the tail in insulating relationship to the conductors on the tail. The tail insulator has an opening adjacent to its end through which the tail extends so that the end portions of the conductors are exposed and can be connected to external circuitry. In alternative embodiments, the tail insulator may extend from the membrane or from an additional layer or covering panel which is positioned in covering relationship to the membrane. Also, the tail may extend from the membrane in which case the tail insulator can extend from either the separator or the substrate.
