Title: Method for measuring length of optical fiber
Inventor: TANAKA AKIRA
IPC: G01M11/00
Filed: 1985-06-07
Abstract: PURPOSE:To measure the length of an optical fiber accurately and easily by measuring the peak wavelength of an output light from the optical fiber. CONSTITUTION:Four optical fibers are used as optical fibers which measure a length. The length of each of these optical fibers is known and the peak wavelength of the light transmission spectrum is constant. An LED consisting of GaAlAs is used as a light emitting element 2. When an input light 3 from the LED is inputted to optical fibers 1, the peak wavelength approaches gradually the peak wavelength of the light transmission spectrum from that of the input light 3 in accordance with increase of a length L. Relations between the optical fiber length L and an output light peak wavelength lambda are shown by a line having a large gradient. Thus, the peak wavelength lambda of an output light 4 from an optical fiber whose length L is unknown is measured to determine the length L accurately.

Title: Band management system in multimedia router
Inventor: IBATA MITSUNORI
IPC: H04L12/801
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To perform communication without falling back a FAX band to a low band by previously registering a terminal type such as telephone/FAX and reserving band width in accordance with a terminal. SOLUTION: When a FAX terminal 31 makes a call out and performs FAX communication, a dial number is exchanged between a PBX 11 and a multimedia communication device 1 through a PBX interface part 101 based on a previously defined procedure. When a band managing part 110 receives a call out frame, it extracts the opposite party dial number in the frame and collates it with a FAX terminal registration table 111. It retrieves whether the opposite party is a FAX terminal or not from the dial number of an incoming destination. When the opposite party is a FAX, band research in a sending end communication device is performed. When a band is reserved, a frame transmitting and receiving processing part 112 sends a call out frame and adjusts whether band reservation is possible or not among the device 1, a repeater and a receiving end device.

Filed: 1990-05-14
Abstract: PURPOSE:To eliminate the crack of a package, the deformation of a wire and the like and to enhance reliability by a method wherein an interconnection pattern formed on a resin cap and a semiconductor chip are connected directly by using a bump, the semiconductor chip is not covered with a resin for mounting use or it is covered with a low-stress resin for mounting use and it is mounted and sealed. CONSTITUTION:A semiconductor chip 3 is housed inside a recessed part 1a of a cap 1; bumps 4 formed on one face are connected to interconnection patterns 2 via inner connection parts 5. That is to say, the chip 3 and the interconnection patterns 2 of the cap 1 are connected via the bumps 4, and no bonding wire is used at all. A board 6 is connected to the interconnection patterns 2 via outer connection parts 7. The recessed part 1a is not filled with a resin or the like. Since the chip 3 is not covered with a resin, no interface which stores moisture exists even when the cap 1 made of a resin absorbs moisture.

Abstract: PURPOSE:To obtain the area of an input point at high accuracy by comparing a reference voltage that varies according to which area on a resistance sheet has the input point with the output voltage of a constant current supply circuit supplying a constant current to the resistance sheet. CONSTITUTION:An erasure level output circuit 12 generates reference voltages V1-V3, and outputs them to an erasure area detection circuit 13.
