A drawing apparatus is connected to a compound design apparatus. The design apparatus includes at least a display for displaying a drawing, a data base device for storing therein reference data to analyze the drawing, a storage for storing therein analysis data of the drawing, and a computing unit connected to the drawing apparatus to analyze the drawing. The computing unit may include a drawing evaluating section for extracting a graphic image of a particular mechanism part from the drawing generated by the drawing apparatus and for evaluating the graphic image, an analysis model generator for generating, according to a profile of the graphic image, an analysis model having a mechanism equivalent to the graphic image, an analyzer for reading mechanical characteristic data from the data base device, supplying the data to the analysis model, and analyzing the mechanism, and an analysis evaluating section for evaluating analysis results attained from the analyzer. The analysis results evaluated by the evaluating section are delivered to the drawing evaluating section, thereby evaluating the mechanism part graphic image.

An audio apparatus includes an electronic graphic equalizer, in which a plurality of frequency characteristics corresponding to various space configurations are stored preliminarily and a plurality of frequency characteristics corresponding to various types of music are also stored preliminarily. Suitable frequency characteristics are selected from these two groups of frequency characteristics according to a specific spatial configuration and a specific music to be reproduced and combined to obtain a frequency characteristics suitable for the configuration and the music.

An alarm device for a vehicle comprises sensors for detecting abnormal states of the vehicle, a logic circuit for receiving the outputs of the sensors and producing one or more alarm speech designation signals and an alarm speech generator responsive to the alarm designation signal. The logic circuit includes a priority circuit for determining the order of precedence of the abnormal states represented by the detection signals on the basis of the degree of emergency, so that the alarm speech is concerned with the most emergent alarm when two or more abnormal states are detected simultaneously. The logic circuit may further include a switch circuit for disabling at least one of the detection signals so that a vehicle driver having taken notice of particular alarms is not disturbed by excessive alarming.
