Abstract: A device, for disobstructing ateriosclerotic lesions in proximity to the origin of lateral branches or bifurcations of an artery. The device includes a stent having two sections. One section is adhered along approximately two thirds of its total length to a balloon. The other section corresponds to the final third of the length of the stent does not completely adhere to the balloon and is partially expanded before its use. A proximal end of a metallic guide wire passes through the mesh of the partially expanded section which has been previously introduced into a secondary branch or bifurcation in the artery. The wire provides an access to the secondary branch for introducing a second balloon or a second stent for the disobstruction of the secondary branch or bifurcation.

Abstract: A semiconductor booster circuit is disclosed that boosts a power-supply voltage to approximately twice the original voltage. When a reference clock signal is at the ground voltage, an inverted clock signal becomes the power-supply voltage, and the power-supply voltage is conducted from the power supply input terminal by way of a third FET transistor and stored in a first capacitor, and the stored voltage of a second capacitor is delivered from an external output terminal by way of a second FET transistor. Conversely, when the reference clock signal is at the power-supply voltage, the power-supply voltage is conducted from the power supply input terminal by way of a fourth FET transistor and stored in the second capacitor, and the stored voltage of the first capacitor is delivered from the external output terminal by way of the first FET transistor.

Abstract: Streams of data including explicit synchronization patterns (such as entire T1/E1) are transmitted utilizing an unstructured data format, while streams not containing explicit synchronization patterns (such as fractional T1/E1) are sent utilizing a structured data format, i.e., the data structure itself provides for circuit alignment at the receiving end. In addition, SDH VC-12 frames are transmitted over the IP network by encapsulating the entire frame (payload and overhead) into an RTP packet. Furthermore, the clock is reconstructed (clock recovery) from the packet stream at the receiver's side.

Abstract: In a label switching router placed at one end of an LSP set by using CRLDP, a bidirectional LSP setup TLV preparing portion prepares a bidirectional LSP setup TLV included in a bidirectional setup label request message transmitted in an up direction to a label switching router placed at the other end of the LSP. Based on an external bidirectional LSP setup request accepted by a bidirectional LSP setup accepting portion, a bidirectional LSP setup TLV analyzer analyzes the bidirectional LSP setup TLV in the message. When the message is received from the label switching router at the other end, a bidirectional LSP processor performs an LSP setup request in a down direction as opposed to the up direction. Based on the analyzed result by the bidirectional LSP setup TLV analyzer, and an explicit route preparing portion prepares an explicit route on which a router to be relayed in the down direction is prescribed.
