An injection molding tool is described for the production of disc-like information carriers, in particular in the form of CD’s andor DVD’s. The printer comprises a platen comprising a print surface, an advancing mechanism adapted for moving a print substrate in a transport direction over the print surface and a print station adapted for providing the phase change inkjet image on a first surface of the print substrate in a print area of the print surface. A first sourcedrain to gate distance is between each first sourcedrain region and the first gate structure. The gradient magnetic field coil device is provided which can suppress generation of eddy current magnetic field even if there is a relative position deviation between the main coils and shield coils. The intake pressure sensor for detecting the intake pressure on the downstream side with respect to the throttle valve is disposed adjacent to a head cover and is attached in a state wherein it is spaced away from an upper face of the throttle body. The bitmap may be generated by drawing the plurality of objects.
