Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for obtaining desired phase of optical characteristics of a Fabry-Perot(FP) etalon, using many photodetectors. SOLUTION: Many photodetectors are matched passively at various positions to an incident light beam to detect optical signals at different phases sent from an FP etalon. The invented FP etalon and a photodetector array are usable as a frequency discriminator in an optical system, having a need for a specified phase which the optical characteristic of the FP etalon has.

Abstract: PROBLEM TO BE SOLVED: To realize a laser module with the use of an existing optical sending circuit for optical communication apparatus using low oscillation threshold lasers, and improve the optical output characteristics at no signal or zero signal time. SOLUTION: A laser oscillation threshold adjusting circuit, having an laser module and an optical transmission circuit in an optical transmission module used for optical communication apparatus, is provided. To adapt a low oscillation threshold laser module 10 to an optical transmission circuit 20 for high oscillation threshold lasers, a resistor 30 is added to connect the anode and cathode of the laser module, and the resistance of the resistor 30 is determined by taking the difference current of a threshold to be raised and the voltage drop between the laser anode and the cathode into consideration.

Abstract: PROBLEM TO BE SOLVED: To provide an integrated circuit comprising a structure where an inter-line capacitance is reduced, and to provide a manufacturing method for an integrated circuit wherein an impurity is prevented from causing a destructive reaction with a conductive element present in the next layer of a multi-layer integrated circuit structure. SOLUTION: A cap layer or barrier layer which prevents an impurity from moving in a low permittivity material prevents the impurity from causing a destructive reaction with a conductive element present in the next layer of a multi-layer integrated circuit structure. Related to an integrated circuit, a diffusion preventive barrier layer is deposited between a first dielectrics layer and a conductive layer above the integrated circuit. The diffusion-preventive barrier layer is the next metal layer which is formed, on the spot, at the dielectrics layer comprising impurity, and further, a process including polishing is performed with a multi-layer dielectrics structure. The on-the-spot deposition at the cap layer or barrier layer prevents a layer comprising impurities from being exposed to an atmosphere, and the cap layer or barrier layer prevents the layer from being contaminated with water content, hydrogen, etc.

Abstract: PROBLEM TO BE SOLVED: To enable a user to restart a program, without penalty of lost time by surely performing exact tracking of execution time and by periodically updating execution time even when a program crush occurs. SOLUTION: Concerning the method for monitoring the use of the execution time of demonstration evaluation software, the number of clocks is monitored while running a software program and through the whole execution, the lapse of execution time is updated periodically. The lapse of execution time is stored inside a key in a concealed file or in software registry. Until the lapse of execution time exceeds a prescribed evaluation time, the program is continuously operated, and then running is disabled until the program is registered by the user.

Abstract: PROBLEM TO BE SOLVED: To provide a superior optical cable fixing structure which can be grounded by fixing a metal wire through easy handling without damaging its coated optical fibers. SOLUTION: In a fixation block 31, a V-sectioned slit 32 is formed to fix a metal wire 1, and a V-shaped cutting tool 33 composed of a couple of cutting parts is provided at the inner part of the slit 32 except its insertion hole part. The angle of the V-shaped cutting tool 33 is equal to the angle of the V-shaped slit 32 and the cutting parts of the cutting tool 33 are arranged along a couple of slit surfaces of the slit 32. The cutting tool 33 is a single member formed of a conductive material such as metal and grounded. The metal wire 1 can be fixed and grounded by the cutting tool 33 in the slit 33 only by pushing the metal wire 1 with an insulating coating 2 into the slit 32.

Abstract: PROBLEM TO BE SOLVED: To provide a system that automatically reassigns an echo canceler to another facility in the case that it is decided that a facility to which the echo canceler has been assigned does not generate vast profit from echo cancelation. SOLUTION: The echo canceling system provided with self-deactivation processing of this invention includes an echo canceler and an echo detector employing an adaptive filter. The adaptive filter decodes an estimate value of an echo signal in existence in an unprocessed signal received from a near-end of a communication channel. The echo detector compares the energy of the unprocessed received signal with the energy of the received signal whose echo is canceled. When the difference is high, the echo canceler is left as active. The difference, that is, the estimated echo energy is small, the echo canceler is deactivated and the echo detector selects the unprocessed received signal as its output. In the case that a plurality of channels for echo cancelation is to be served, the deactivated echo canceler is reassigned to serve for another communication channel.

Abstract: PROBLEM TO BE SOLVED: To provide an EMI(electromagnetic interference) module cover by which EMI is reduced. SOLUTION: In the EMI cover, conductive side panels have elastic canti-levers formed from them and each of the canti-levers has a fixed end formed as part of the side panel and a free end without modular coupler. By this constitution, when the module is to be mounted on the chassis, the elastic canti-levers can be bent. The elastic canti-lever part has bosses near the movable free end. The bosses protrude from the side panel toward the outside by an enough length for providing a conductive pass between the conductive surfaces which are adjacent to the side panels when the module is mounted on the chassis.

Abstract: PROBLEM TO BE SOLVED: To provide a method and device for reducing accumulation of static electricity, while a semiconductor wafer surface is being cleaned (cleaned or rinsed) in order to protect circuits and devices formed on the semiconductor wafer. SOLUTION: This method of cleaning a semiconductor wafer surface has steps of introducing an additive to deionized water to prepare a conductive cleaning solution (A) and cleaning the semiconductor wafer surface with the conductive cleaning solution (B). The additive is preferably carbon dioxide gas and forms ions in the conductive cleaning solution by reaction with deionized water. Carbon dioxide (CO2) is made to react with deionized water (H2O) and forms H+ ions and HCO3- ions.

Abstract: PROBLEM TO BE SOLVED: To provide a device and a method in which optical beams are passively redirected in a relatively simple, effective and inexpensive manner. SOLUTION: An optical communication system includes a device and a method in which optical signals, that pass the device, are displaced in a lateral direction or sterred. The system includes a transmitting device 22, which transmits the optical signals, a receiving device 24, which receives the signals, and at least one optical guiding element 10. The element 10 is a transmission medium to capture and transmit optical information by having tip part shapes. For example, a portion of light beams, which propagate in a first direction and enter into a first tip part 12, are practically redirected along a transmission axis. Moreover, the light beams which propagate along the axis outside a second tip part 14, are redirected to a second direction that is displaced in a lateral direction from the first direction.
