Abstract: PROBLEM TO BE SOLVED: To provide an improved technique for obtaining the delay characteristics of semiconductor layers in a multilayered stack by achieving desirable changes in optical thickness and composition. SOLUTION: A saturable absorber mirror which is used at the time of locking the mode of a laser uses the multilayered stack of compound semiconductor layers which is arranged under a multilayered stack of dielectric layers forming a smooth edge filter and alternately contains narrow and broad energy band gaps. The narrow energy band gap layers are alloy-modulated in a digital mode and the energy band gaps of the layers are changed so that the mirror offers a desired group-delay dispersing characteristic.

Abstract: PROBLEM TO BE SOLVED: To provide a tracing system for a jumper cable containing both optical fibers and electrical wires. SOLUTION: Conventional problems are solved by a system composed of optical receptacles, which are mounted on a pair of patch panels and which contain metallic conductors, and jumper cables which contain optical fibers and electrical wires terminating in a plug connector at each end and which are connected to the optical receptacles by the plug connectors. Each patch panel includes manually operated switches and electrical circuitry containing a light emitting device, with each circuit electrically connected to a metallic conductor inside the optical receptacle on each patch panel. If the switch on one patch panel is in the active state, a voltage in the metallic conductor is applied, making the light emitting device give off light in the corresponding receptacle on the other patch panel. If the switch is in the normal state, the light emitting device gives off no light.

Abstract: PROBLEM TO BE SOLVED: To provide a method for transmitting a paging message used for a base station in a wireless communication system. SOLUTION: The method for transmitting a paging message used for a base station in the wireless communication system includes a step of adopting a super paging time slot format, where super time slots periodically repeated are included to transmit the paging message to a wireless terminal. The super time slot has time slots, and each time slot is used to transmit the paging message to the wireless terminal.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method for metallic-testing a subscriber line that provides both voice and digital subscriber line services. SOLUTION: The voice service is provided by a voice switch and the DSL service is provided by a digital subscriber line access multiplexer (DSLAM). Each of them includes a metallic line test unit. The voice line in the voice switch has a connection to a first metallic line test bus connected to the voice switch metallic line test unit via a first relay set. The DSL line in the DSLAM card has a connection to a second metallic line test bus, which is also connected between the DSLAM metallic line test unit and the subscriber line. A second set of relays control the connection of the metallic line test bus to the subscriber line. A signal is sent from either metallic test unit to cause the relays to change to provide a clear path for metallic testing.

Abstract: PROBLEM TO BE SOLVED: To provide an improved shape memory material for an optical fiber connector application. SOLUTION: A connector for joining an optical element, especially an optical fiber is disclosed. The connector is a sleeve made of a simple shaped memory polymer(SSMP) into which the optical fiber is inserted, and the sleeve is heated to collapse the sleeve around the optical fiber. The SSMP material is not crosslinked and can be manufactured by a variety of techniques including extrusion. Various methods for forming the bore of the connector and expanding the size of the bore from the memory state to the metastable state are disclosed.

Abstract: PROBLEM TO BE SOLVED: To provide a method for monitoring the performance of part of a path in a communication transport network and the network. SOLUTION: A network element has a performance monitoring facility operating to report overall error rate at the element in the network path and the communication transport network is equipped with a management system which calculates the performance of a segment of the path between two elements from the reported overall error rates at the element. Monitoring can be performed by management software by using standard interfaces for gathering the reported error rates. Since not are paths require TCM, the processing that the network management system requires is not great.

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for restricting call terminations, when a mobile unit is roaming. SOLUTION: This invention provides the method and apparatus for restricting call terminations to a roaming mobile unit. A serving MSC(mobile switching center) that is an MSC to provide call processing to a mobile unit which is not a home MSC among mobile units, sends a registration notification request to the home location register(HLR). The HLR retrieves the termination access code parameter from itself and sends the parameter to the serving MSC. The termination access code parameter includes a value that indicates if the mobile unit is allowed to accept roamer port calls. A VLR(visitor location register) associated with the serving MSC stores the parameter. When a call request comes in the serving MSC and requests a roamer port call with the mobile unit, the serving MSC checks the value of the termination restriction code to determine if the roamer port call should terminate, or complete, the call.

Abstract: PROBLEM TO BE SOLVED: To provide an outer coating layer of double coated optical fibers which improves the microbending loss. SOLUTION: The coating layer is improved by the addition of very small clay platelets. The clay platelets are aligned along the axis direction of optical fibers. The clay platelets are small enough to be essentially transparent to the UV curing radiation.

Abstract: PROBLEM TO BE SOLVED: To provide a method for determining the feature of particles in a colloidal suspension while the particles are settling. SOLUTION: The method includes the step of measuring changes in strength between interference patterns produced by combining partially coherent first and second radiation portions while the particles are settling. The first and second partially coherent radiations are derived from the same source; the first portion permeates a portion of the suspension while the second portion permeates a reference path.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system that allow a mobile phone to record phone conversations or a memo of a user. SOLUTION: In this system a function for recording phone conversations and memo is given to a user and the user manages the function similarly to the case with voice mail, and a recorder is incorporated into a mobile network system or the mobile phone. The user can record important information for a phone conversation without the need for using a tool of writing or writing paper.
