Abstract: An azimuth processing device is designed for outputting azimuth data based on measurement data sequentially output from a compass sensor. In the device, an accumulation section selectively accumulates substantially new pieces of the measurement data. An offset data updating section updates offset data of the compass sensor based on plural pieces of the measurement data accumulated by said accumulation section. An azimuth data output section outputs the azimuth data based on substantially newest measurement data and the offset data.

Abstract: Detection is made of an activated direction of a vehicular operator device capable of being activated in at least two directions. In response to activation, in a first direction, of the operator device, informing sound is generated which varies over time with a first characteristic, and, in response to activation, in a second direction, of the operator device, informing sound is generated which varies over time with a second characteristic generally opposite to the first characteristic. For example, when a right turn is instructed, informing sound is generated with a characteristic to progressively raise the sound pitch from a relatively low sound pitch, while when a left turn is instructed, informing sound is generated with a characteristic to progressively lower the sound pitch from a relatively low sound pitch (, or vice versa).

Abstract: In accordance with a traveling state of a vehicle, a tone indicating, for example, that the vehicle is traveling is generated as a tone of a first performance part. Also, a variation in any of various states of the vehicle, such as an operating condition of a winker or flasher, is detected, and a tone corresponding to the detected state is generated as a tone of a second performance part. For example, ensemble data including the first and second performance parts may be employed.

Abstract: A sound source circuit is provided for a telephone terminal to reproduce chorus-effect imparted musical tones as incoming call sound or hold sound. Herein, original musical tone data &ohgr;c1 are slightly modified in pitches to produce musical tone data &ohgr;c2 with respect to a prescribed tone color. These musical tone data are periodically selected and synthesized together to form musical tone signals having a chorus effect, based on which the chorus-effect imparted musical tones be reproduced for the telephone terminal such as a portable telephone.

Abstract: A portable telephone apparatus has a communication unit for receiving a call signal to inform a user of an arrival of a call so that the user can start a talk, and a reproduction unit for processing music data in response to the call signal to reproduce a piece of music composed of two or more parts including a melody part and an accompaniment part so as to audibly notify the user of the arrival of the call. Allowing the user to compose music without need for an excessive amount of work, score data for a melody is inputted first (IN1), and style information and chord information are inputted in the process of creating an accompaniment part. Then, accompaniment data for drum, bass and chord parts are selected from a ROM 12 or RAM 11 based on the inputted style and chord information (SE1). The selected accompaniment data of two or more parts are merged with the score data of the melody (PR1) to create music data.

The system further includes a scale selector which is manually operable. Depending on the selected map scale, the displayed map is magnified or reduced.

Abstract: A navigation information announcing system for a motor vehicle comprises a tape player, circuitry for measuring the distance actually travelled by the vehicle, circuitry for reproducing distance information pre-recorded on a magnetic tape, and a comparator. A distance indicated by a reproduced datum from a magnetic tape is compared with the distance actually travelled so that the tape player performs a pause operation until the two distances equal each other. When these distances equal each other, the normal playback operation is reestablished so as to reproduce oral information pre-recorded on the magnetic tape, supplying the vehicle driver with directional information.

Abstract: An electronic trip meter for an automotive vehicle comprises an up-down counter, a memory circuit, an adder-subtractor, a display circuit, and other auxiliary circuits. The up-down counter produces a signal indicative of a remaining distance to a goal by subtracting an actually travelled distance from a preset distance between two points for displaying the remaining distance by the display circuit. When the vehicle reaches the goal, the adder-subtractor produces a signal indicative of the actually travelled distance in accordance with the output signals of the up-down counter and the memory circuit in which the preset distance is stored. The adder-subtractor output signal is then fed to the up-down counter for displaying the actual distance between the two points and to the memory circuit for correcting the preset distance whereby a remaining distance to the starting point in a return trip is easily and accurately obtained. The trip meter may be also utilized for a trip beyond the goal.
