An electronic vehicle horn outputs a warning sound by exciting a diaphragm using a piezoelectric device that is driven with a composite signal generated, in part, by modulating a first fundamental square wave with a first modulating square wave and setting a frequency deviation at the time of the modulation in a predetermined range, modulating a second fundamental square wave with a second modulating square wave and setting a frequency deviation at the time of the modulation in a predetermined range, and generating the composite signal by mixing the modulated first fundamental square wave and the modulated second fundamental square wave.

Provided are a device for automatically generating route restriction information of intersections between main roads and narrow streets, and a method therefor. With respect to a specific intersection which is an intersection between a main road and a narrow street, firstly, it is determined to prohibit a right turn and passing through the intersection. Under these conditions, when it is sufficiently confirmed, by using external information, that the right turn and passing through the intersection can be allowed at the specific intersection, the route restriction regarding the direction is released. Probe information and traffic restriction data are used for the external information.

Device and method for generating route restriction information of intersection, computer program for generating route restriction information of intersection, and recording medium for recording computer program

A primer () for forming a resin frame () is formed on an outer end portion () of a separator () of a fuel cell. An electrodeposition coating device () includes an upper frame () and a lower frame (), and covers only the outer end portion () of the substrate () with a center portion () of the substrate () left uncovered. When the substrate () is sandwiched between the upper frame () and the lower frame () of the electrodeposition coating device (), an annular electrodeposition chamber () is formed with the outer end portion () of the substrate () located in the electrodeposition chamber (). Then, the electrodeposition chamber () is filled with an electrodeposition coating solution (), and electrodeposition coating is performed. Then, cleaning is performed by using purified water, and drying is performed by using hightemperature air.
