Abstract: There are provided a method of preparing nano-carbon comprising evaporating a material to be arced containing carbon as a main component by means of arc discharge which does not necessarily require a process container and so on, but uses an apparatus having a welding arc torch or an analogous structure to generate soot, a method of preparing an electron emitting source by supporting the soot, and an apparatus for preparing the same. A torch electrode 10 of an arc torch 1 as a first electrode is placed opposite to a material to be arced 2 using graphite as a second electrode. A voltage is applied between the torch electrode 10 and an edge portion of the material to be arced 2 to generate arc discharge, to evaporate the edge portion of the material to be arced 2 exposed to the arc discharge, to generate soot. The soot thus generated is deposited on the surface of a substrate opposite to an arc discharge-generating area through a mask having a patterned opening.

Abstract: A steering control device is provided that synchronizes the driving operations of swash plate control servomechanisms. In roll control, the control amount adjustment circuit FR separates and converts the roll control signal R into a roll servo drive control amount and a collective pitch servo drive control amount. The offset correction circuit OR offset-corrects the converted control amounts and outputs a servo control signal converted into the roll servo control amount RR and a servo control signal converted into the collective pitch servo control amount RC. The adder receives the roll servo control signal and the collective pitch servo control signal and adds them with a pitch control signal and a collective pitch control signal. Thereafter, the synchronous circuit DR synchronizes the added signals. The roll servo control output SR, the pitch servo output SP, and the collective pitch output SC are respectively output to the servo mechanisms with the same timing.

Abstract: A resolver for detecting the displacement amount of a passive body is provided with an excitation winding or a detection winding. The detection is based on a detection signal outputted from the detection winding as a result of an excitation signal inputted to the excitation winding. The excitation winding and/or the detection winding are composed of a combination of one or more sheet coils having one or more bore portions. The sheet coils are arranged at prescribed intervals in the lengthwise direction of a magnetic core to which the sheet coils are attached. A plurality of coil-storing grooves formed in a direction perpendicular to the lengthwise direction are provided in the core surface of the magnetic core. The coil portions of at least two portions of the respective sheet coils are accommodated in the coil-storing grooves.

Abstract: A capacitive pressure sensor (1) using mutual capacitance type is provided. The capacitive pressure sensor (1) comprises a dielectric layer (2), a ground electrode (3), transmission electrodes (4), reception electrodes (5) and a controller (6). The transmission electrodes and reception electrodes have a matrix structure (FIG. 3). An electric field is generated between the transmission electrodes and the reception electrodes by the controller. When the dielectric layer is deformed by a pressure applied to the ground electrode, a capacitance of the dielectric layer changes. The controller detects the unit detection area (10) where the capacitance changes and the pressure corresponding to the change in the capacitance.
