A manually drivable food cutter includes a cap with a axle journal, a blade shaft including one or more blades disposed thereon, a vessel connected to the blade shaft, a base connecting the cap and the vessel, a gear shaft set above the base, and a gear part transmitting the rotation of the cap to the blade shaft on the base, the gear part including one or more gears. In the present invention, a silicon substrate is annealed with N2O gas under a low pressure of 10100 Torrs to form an oxynitride film on the silicon substrate, or a previously formed thermal oxide film is annealed with the same gas under the low pressure to be nitrified. In order to improve the precision in the diagnostic support technology, the property of data acquired by an optical organism measurement system is utilized in order to create and display information representing a change in the condition of each person. Because the pressure-receiving portion of the thrust receiver rotates about the axis of the shaft portion accompanying the expansion and contraction of the trim rod, a twisting generated at the abutment point can be minimized to suppress generation of an abnormal sound. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle.
