摘要： PROBLEM TO BE SOLVED: To reduce the reactive current of an optical element by forming a current/voltage impressing electrode structure in the partial area of an optical waveguide and an insulating part in a buffer layer, a clad layer, or both of the buffer and clad layers positioned in a light beam spot transforming area. SOLUTION: After a silicon oxide film 106 is formed on the whole surface of a substrate 102, proton implanted areas 107 are formed in a waveguide area having a uniform film thickness and a thick tapered area except parts of about 50μm in thickness by implanting protons into a clad layer 104 through ion implantation by using a photoresist as a masking material. After removing the photoresist mask, silicon oxide films 106 which are formed on the ridge waveguide and into which the protons are not implanted are removed. Then an upper electrode 108 is formed by using an oblique vapor deposition method so that electrodes may be formed on the side walls of the ridge. Electrode windows are formed only in the parts which do not contains implanted protons. The reactive current of a waveguide type optical element can be reduced by providing the proton-implanted areas in no-current injected areas.

摘要： PROBLEM TO BE SOLVED: To provide a detector for detecting a polarity of a line voltage of an analog telephone line with a simple and inexpensive circuit configuration that completely isolates a secondary side from a primary side and can extract a detection output of a line voltage polarity of the analog telephone line. SOLUTION: The detector for detecting a polarity of a line voltage of an analog telephone line is provided with a discharge circuit where a capacitor is connected to the analog telephone line via a high resistance resistor and a switch is included to cause a discharge current to flow from the capacitor and with a detection circuit that has the secondary side placed while being isolated from the primary side to detect flowing of the discharge current to the primary side. With the switch turned off, the capacitor stores a charging DC voltage by the charging current and the detector is configured such that when the switch is closed, utilizing the detection of the direction of the discharge current flowing through the discharge circuit can detect the polarity of the voltage between terminals L1, L2 of the telephone line.

摘要： PROBLEM TO BE SOLVED: To provide an element structure for confining an injected carrier in a luminescent region, producible as a silicon or germanium light-emitting element, and a manufacturing method thereof.SOLUTION: A narrow passage for a carrier, or a one-dimensional or two-dimensional quantum confinement region, is fabricated between an electrode and a luminescent region. Due to quantum confinement, a band gap in that portion is widened, constituting an energy barrier for both electrons and holes, so that a similar effect to that of the heterostructure of an ordinary III-V group semiconductor laser is obtained. Because no other elements than those used in an ordinary silicon process are used, with only controlling the shape of the element involved, manufacturing at low cost is possible.

摘要： PROBLEM TO BE SOLVED: To efficiently duplicate the session information of an active gateway server which performs a normal operation to a standby gateway server standing by for a fault or the like of the active gateway server, in an access gateway device which controls the access of a user in a network system. SOLUTION: Changed session information for each call or data within the changed session information is duplicated from the active gateway server to the standby gateway server in the order of priority. The duplication of high priority session information is achieved even when the band of a network is insufficient or the like, and low priority session information which cannot be duplicated is duplicated when the band or the like of the network is sufficient.
