Abstract: A driving device of an IGBT includes a high potential side switch device group having a plurality of switch devices and, one end of each switch device being connected to a high potential side; a low potential side switch device group having a plurality of switch devices and, one end of each switch device being connected to a low potential side; an drive type selective input terminal to which a drive type selection signal corresponding to drive type of the IGBT connected to the driving device is inputted; a direct drive type control unit and an indirect drive type control unit generating a control signal controlling complementarily the high potential side switch device group and the low potential side switch device group corresponding to the drive type of the IGBT; and a selector selecting the control signal controlling the high potential side switch device group and the low potential side switch device group corresponding to an inputted drive type selection signal.

Abstract: An inkjet recording medium obtained by forming a coating layer containing a pigment and a binder on the surface of a base material and coating layer is subsequently pressed onto a heated mirror finished surface to dry to form an ink absorbing layer through a cast coating method, wherein pigment contains a colloidal silica that has a primary particle diameter of from 10 nm to 100 nm while the ratio of the secondary particle diameter to primary particle diameter is from 1.5 to 3.0.

Abstract: A driving device 10 of an IGBT 1 comprises a high potential side switch device group having a plurality of switch devices M1 and M1?, one of ends of each switch device being connected to a high potential side; a low potential side switch device group having a plurality of switch devices M2 and M2?, one of ends of each switch device being connected to a low potential side; an drive type selective input terminal 10b to which a drive type selection signal corresponding to drive type of the IGBT 1 connected to the driving device 10 is inputted; a direct drive type control unit 23 and an indirect drive type control unit 24 generating a control signal controlling complementarily the high potential side switch device group and the low potential side switch device group corresponding to the drive type of the IGBT 1; and a selector 25 selecting the control signal controlling the high potential side switch device group and the low potential side switch device group corresponding to an inputted drive type selection sign

Abstract: A practice mode can be inserted into an RPG program without giving the player a sense of boredom. Because the distinction between the practice mode and the game is eliminated, the player is not given the sense that the progress of the game is being interrupted and the problem of the player losing interest can be resolved. Also, because of the construction of a new training system wherein training for special moves, that are difficult to remember, is easily stored on the screen, the player can focus on the progress of the game and can have increased interest in the game.
