  • Patent number: 10240785
    Abstract: A solenoid valve driving apparatus includes switching means for ON/OFF-controlling application of a direct current voltage to a solenoid of a solenoid valve, and signal outputting means. A first period and a consecutive second period are set as a valve opening operation period of the solenoid valve. When the signal outputting means outputs the PWM signal to the switching means, a duty ratio of the output signal is set to be higher in the second period than in the first period so that a power supplied to the solenoid is larger in the second period than in the first period. As a result, a valve opening operation is performed in the solenoid valve reliably, and loud noise generation during the valve opening operation is suppressed.

    Abstract: A corrosion-resistant semiconductor device includes fuse elements that can be cut by laser light. An upper portion of the fuse elements is covered with a porous insulating film so that, when laser light irradiated from a rear surface of a semiconductor substrate is collected at selected fuse elements, the fuse elements generate heat, expand, and rupture. An array of intersecting metal lines forming windows is disposed over the fuse elements to permit rapid expansion of the fuse elements when irradiated with the laser light. A silicon nitride film having a uniform thickness is formed on a front surface of the semiconductor device to prevent entry of moisture.
