To carry out drying of printing ink with the use of Nano sized high-temperature dryness steam. Nano sized high-temperature dryness steam being clustered on Nano oder is generated and jetted to the print side of printed material so that the Nano sized high-temperature dryness steam imparts intramolecular vibrational energy to ink of the print side. Consequently, the Nano sized high-temperature dryness steam being clustered on Nano oder not only passes through fiber pores in the printed material but also collides with the ink of the print side. The Nano sized high-temperature dryness steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink containing polar molecules. The ink is dried by the intramolecular energy.

A recessed portion is provided in first and second insulating films, the first insulating film being stacked on a semiconductor wafer, the second insulating film being stacked on the first insulating film. The first and second insulating films are processed to form wiring in a formation region of the semiconductor wafer in which an acceleration sensor is to be formed. After a sacrificial film is stacked on the wiring and processed, a conductive film is stacked on the wiring and processed to form a plurality of thin film structures in the formation region. The recessed portion surrounds the formation region.

A drive apparatus for a hybrid vehicle is provided with a motor, a clutch that transmits and cuts off a driving force between the motor and an engine, and a control device that performs an operation control for the motor and the clutch. If there is an engine start request during driving of a wheel by the motor, the control device increases an operating pressure of the clutch to start the transmission of torque from the motor to the engine side, and detects a transmission torque to be transmitted via the clutch. The control device also performs a control that sets an output torque of the motor as equal to a torque that is the sum of the transmission torque and a request torque for wheel driving, which is determined based upon an accelerator opening.

In a semiconductor device having an SOI structure and a method of manufacturing the same, influence by a parasitic transistor can be prevented, and no disadvantage is caused in connection with a manufacturing process. In this semiconductor device, an upper side portion of a semiconductor layer is rounded. Thereby, concentration of an electric field at the upper side portion of the semiconductor layer can be prevented. As a result, lowering of a threshold voltage of a parasitic transistor can be prevented, so that the parasitic transistor does not adversely affect subthreshold characteristics of a regular transistor. Owing to provision of a concavity of a U-shaped section, generation of etching residue can be prevented when etching a gate electrode for patterning the same. Thereby, a disadvantage is not caused in connection with the manufacturing process.
