摘要： A manufacturing method for key tops includes the steps of molding a light-shielding film on a to-be-peeled shield by a plane printing, effecting colored printing to provide a readout part at a predetermined position on it in the state of a plane sheet prior to the 3-D molding, then sucking a printed light-shield film sheet on a metal mold with an evacuation system, adsorbing said light-shield film sheet onto the wall face in the metal mold. A push mold may be used with a suction system so as to be positioned in the female mold. Materials such as silicone are put into this metal mold for one-piece molding. A laser processing is effected on the surface of a key top prepared in a 3-D shape to form a desired pattern. By making the light-shield printing and pattern printing in the state of a plane sheet prior to the 3-D molding and effecting only a pattern processing by laser cut in the state of a stereographic shape, a laborious coating has been omitted which also results in improved accuracy of printing and at the same time a reduced number of steps.

摘要： An optical line terminal (OLT) that configures a passive optical network (PON) system in cooperation with an optical network unit (ONU). The OLT has a controller to control a link state with the ONU. The controller generates, in one case, a control signal specifying a first low power consumption mode in which the ONU operates in the low power consumption mode in an upstream direction, and generates, in another case, the control signal specifying a second low power consumption mode in which the ONU operates in the low power consumption mode in both upstream and downstream directions. Further, the generated control signal is transmitted to the ONU.

摘要： A communication apparatus includes a main-data processing unit that performs predetermined data processing on input data, and operates by switching two states of a sleep state as a state where an operation of the main-data processing unit is stopped and a normal state as a state where the main-data processing unit is operating. The communication apparatus includes a filtering unit that extracts communication state information for indicating a communication state from the input data, and a signal processing unit of a sub-data processing unit that shifts the main-data processing unit to a sleep state or a normal state based on the communication state information.

摘要： The present invention provides a communication apparatus on a subscriber side that, in a point to multi-point communication system, transmits upstream data transmitted from a lower-level device to a station-side device based on a data transmission start time and a transmission duration time notified from the station-side device. The communication apparatus includes a logical-link control unit that determines number of links to be used, which is number of logical links to be used for an upstream data transmission in a next bandwidth update cycle, based on an accumulated data amount in an upstream buffer unit that accumulates upstream data to be transmitted to the station-side device.

摘要： An OLT transmits an inquiry frame for checking a link and checking a data accumulation amount from an ONU. The ONU returns an inquiry response frame. When the ONU detects no uplink-traffic, the ONU writes to that effect on the response frame and transmits the response frame to the OLT. The OLT monitors a downstream traffic. When the OLT recognizes, based on a result of the monitoring or the inquiry response frame, no uplink or downstream traffic, the OLT instructs the ONU to transition to a low power consumption mode. When the ONU receives the instruction, the ONU transitions a function unit corresponding to instruction content to the low power consumption mode. When the ONU does not receive the inquiry frame for a predetermined time, the ONU transitions function units other than a function unit that performs communication control to the low power consumption mode. The OLT stops the transmission of the inquiry frame while the subscriber side apparatus transitions to the low power consumption mode.

摘要： A key switch wherein a key top 1 made of thermoplastic resin and a extruding part 2 made of thermoplastic elastomer are integrally formed, thereby improving clicking touch of a contact member, such as a metal belleville spring, a resin film dome or the like, which is placed underneath the extruding part and preventing breakage and laceration of the contact member. Further, a key switch is constructed such that extruding parts 2 of a plurality of key tops 1 are integrally linked by means of a U-shaped bridging member 3 made of thermoplastic elastomer, thereby causing elastic deformation of the bridging member 3 at the time of pressing one of the plurality of key tops 1 so that an extruding part 2 of an adjacent key top is prevented from operating together.
