Abstract: A radio receiving apparatus is used at a sporting event to provide a spectator with additional information and contact with the participants in the event. In an automobile racing event, each of the automobiles can be equipped with a two-way radio for communication between the driver and the crew as well as with a telemetry transmitter for sending data concerning the operation of the automobile. The telemetry data is combined with other information relating to the car's involvement in the race and this data is combined to produce parameter data. A hand-held receiver receives both the audio conversation and the parameter data for one of the selected cars and produces audible sounds and concurrently produces a display of a graphic image on a screen with information derived from the parameter data. Thus, the user of the receiving apparatus can both hear a selected driver and at the same time see a display of performance information about the car and driver in the race.

Abstract: An object of the present invention is to provide a method of double color-molding a key top that is superior in design. In order to achieve this object, according to the method of double color-molding a key top provided in the present invention, at a first shot, a light-permeable resin layer is injection-molded, and simultaneously, a convex portion that corresponds to a planar shape of a closed loop in a letter, figure, sign, etc., is formed on a back surface of the light-permeable layer. In a second shot, a light-shielding resin layer is injection-molded on both an outer region and an inner region which are defined by a convex pattern of the convex portion on the back surface of the light-permeable resin layer. Since a gate trace, which remains after performing the gate-cut on the light-shielding resin layer, resides inside the key top, it is invisible from the outside of the key top. In this way, the design of a key top can be improved.

Abstract: An object of the present invention is to reduce unwanted voice echoed back to the transmitting party in an IP telephone. In order to achieve this object, in the curl cord of the present invention, two microphone lines connected to a differential input type microphone are respectively wired at approximately the same distance from a single speaker line connected to a single end output type speaker. Thereby, noise signals caused by cross-talk to the microphone lines from the speaker line transmitting the voice signal of the transmitting party will be of the same phase and same amplitude. By cancelling out these noise signals by means of common mode rejection in the differential amplifier provided in the base unit, it is possible to reduce the echoing back of unwanted voice to the transmitting party.
