Title: Route changeover control system, changeover control method and recording medium
Inventor: SHINTANI KAZUNORI
IPC: H04L1/22
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To solve a problem of selecting a faulty AIS frame even when an original active route is normal so long as the faulty AIS frame continues (until AIS is detected) in a transmission system of a redundant configuration including the active route and a standby route. SOLUTION: A changeover control section 410 uses information outputted respectively from a changeover trigger detection section 408 that detects a changeover trigger from a phase matching section 101 in a reception node that matches a phase of a signal from a route X with a phase of a signal from a route Y and information from a faulty AIS frame detection section 409 that detects a 'faulty AIS frame' and controls a SEL section 411. Though the configuration above, non-break changeover control can be realized.

Title: Insulated-gate field-effect transistor
Inventor: ISHIKAWA TOMONORI
IPC: H01L21/338
Filed: 1988-06-22
Abstract: PURPOSE:To perform a higher speed operation by employing AlAsSb, AlPSb or AlSb as a gate insulating layer and InGaAs or InAsSb as a channel layer. CONSTITUTION:Since an InGaAs layer or an InAsSb layer is employed as a channel layer 10, the drift speed of electrons is accelerated in an element channel. That is, these material have small effective mass of the electron and large mobility. Further, the decrease in the drift speed of the electron in a high electric field can be suppressed. Further, since a gate insulating layer 11 is formed of AlAsSb, AlPSb, AlSb, a large conduction band discontinuity is provided between the InGaAs and the InAsSb as the channel layer. Thus, since its gate breakdown strength is large and the high concentration secondary electron gas can be induced that much, a high speed operation can be performed.
