A non-contact heat fixing toner, comprising a binder resin, a colorant, an infrared absorbing agent, a first wax and a second wax, wherein a difference between the maximum peak temperature in the differential thermal curve in the first wax and Tg of the binder resin is within the range from \u22125 to +10\xb0 C. Carrier wafers and wafer arrangements of this type can be used in particular in the field of handling technology of semiconductor wafers. Mechanisms for agitation may be integral and removable with the growing tank or may be adapted for a quick connection and disconnection with the growing tank. The refresh read operation uses a reference resistance with a smaller margin from a resistance distribution than a normal read operation. When the value of a signal representative of the remaining amount of fuel in a fuel tank becomes lower than a predetermined threshold value, the control device controls the first and second inverters such that the voltage level of the alternating voltage is changed in order to notify a user external to the vehicle of the low remaining amount of fuel. The hydraulic controller for a hydraulic drive unit includes a housing that includes an electric motor housing configured to house an electric motor, an oil pump housing configured to house a hydraulic pump, and a valve housing configured to house valves are integrated together.
