Abstract: In an electric load driving device, in the case of a high-side output mode, an output FET is supplied, when connected with a higher-potential side than a load, at its gate with a boosted voltage higher than a battery voltage in response to one control signal as selected from two control signals by a switch signal. In the case of a low-side output mode, the FET is supplied, when connected with a lower-potential side than the load, at its gate with the battery voltage in response to the selected signal. These cases are switched in response to a signal indicating the bit value of the output mode setting data which are stored in advance in a nonvolatile memory.

Abstract: A method for blow molding a superplastic metal plate by in relation to time applying to it pneumatic pressure that is based on a maximum value of a strain rate of the superplastic metal plate as a set pattern of pneumatic pressure in relation to time when the metal plate is subjected to a high-speed blow molding after being heated to a desired temperature, comprising the steps of: entering data on a shape into which the metal sheet is to be blow molded and on properties of a material of the metal plate to store the data in a storage; determining a set pattern of a pneumatic pressure in relation to time from the entered data on the shape and the properties of the metal sheet; dividing the set pattern of the pneumatic pressure into an appropriate number of parts in relation to time; determining the values of parameters for controlling the pneumatic pressure for each part divided from the set pattern of the pneumatic pressure; and controlling the pattern of the pneumatic pressure using the determined values of t
