In a switching power supply circuit of the invention, a low-voltage node capacitor is connected between a primary-side low-voltage stable potential node and a secondary-side low-voltage stable potential node, and a high-voltage node capacitor is connected between a primary-side high-voltage stable potential node and an anode of a rectifier element. Thereby, it is possible to provide the switching power supply circuit which achieves, with a simple configuration, both of noise reduction and potential stabilization of stable potential nodes.

Switching power supply circuit with reduced noise and potential stabilization of stable potential nodes

A switching power supply circuit includes a pair of input nodes to which an input voltage is applied, a pair of output nodes from which an output voltage is outputted and to which a load is connected, a cascode element and a coil connected between the input node and the output node, and a control circuit outputting a drive signal that controls a conduction state of the cascode element. The control circuit controls the conduction state of the cascode element in response to a potential of a point connecting a normally-on type transistor and a normally-off type transistor that constitute the cascode element.

Switching power supply circuit

A mold-in fastening member which is composed of a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate. The mold-in fastening member bends in conformity with a two- or three-dimensionally complicated shape of a molded article. The mold-in fastening member prevents the surface having the engaging elements from being covered with a foamable liquid molding resin during a mold-in process, thereby preventing the engaging elements from losing the engaging function.

Hooking member for in-mold molding

A hook surface fastener excellent in the heat resistance, flame resistance, retention of hook shape, and pull-out resistance of hook engaging elements (fibers). The hook surface fastener is composed of a base fabric and the hook engaging elements formed on the base fabric. The base fabric is a woven fabric composed of warp yarns, weft yarns and fibers constituting the hook engaging elements. The warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers. The weft yarns are substantially non-twisted, paralleled yarns of polyphenylene sulfide fibers and heat-fusible fibers having a melting point or softening point each being 230&#xb0; C. or lower. The polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0% so that the retention of hook shape is good. The fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers. Therefore, the pull-out resistance of the hook engaging elements (fibers) is good even if a resin coat layer is substantially not provided on the back surface of the base fabric. A hook surface fastener substantially free from the resin coat layer has a good heat resistance and flame resistance.

Hook surface fastener

A fabric separable fastener member is provided which comprises a fiber for a base fabric and a fiber for a fastening element firmly anchored by the fused fiber for the base fabric and which is excellent in flexibility and durability without a back-coated layer. The separable fastener member comprises (&#x3b1;1) a ground warp, (&#x3b1;2) a ground weft containing a binder fiber, and (&#x3b1;3) a pile yarn, and the pile yarn (&#x3b1;3) is anchored by the fused binder fiber. In the separable fastener member, each of the ground warp (&#x3b1;1), the ground weft (&#x3b1;2) and the pile yarn (&#x3b1;3) comprises a polyester fiber, the mass ratio of the ground warp (a1) relative to the ground weft (a2) is 40/60 to 80/20, and the mass ratio of the total amount of the ground warp (a1) and the ground weft (a2) relative to the pile yarn (a3) is 90/10 to 50/50.
