A susceptor device comprises a base body, an electrostatic absorbing inner electrode which is disposed on a bottom surface of the base body, a power supplying terminal, an insulating sprayed layer which coats the electrostatic absorbing inner electrode and a connecting section for the power supplying terminal and the electrostatic absorbing inner electrode, and a temperature controlling section. The insulating sprayed layer and the temperature controlling section are attached together unitarily via the bonding agent layer. The flange of the base body fits to a notched section of the temperature controlling section such that the electrostatic absorbing inner electrode, insulating sprayed layer, and the bonding agent layer should be sealed from thereoutside. It is possible to form a thin supporting plate and improve controllability for temperature on the plate sample and transparency for the plasma.

A power converter for converting energy from a green power unit as e.g. a solar cell into energy fed into the commercial grid is described. The object is to provide a versatile modularized power converter with eased access to control of the power switches. Another object is to improve the electrical efficiency. This is achieved by using an independent controller on a DC / DC module and an independent controller on a DC / AC module, whereby the two independent controllers communicate with each other and the outside world by means of a communication bus. Further, the DC / DC module of the power converter comprises a transformer which transfers energy from the DC / DC module to the DC / AC module. This design enables independent control of the modules and eases controllability of the power switches in order to suppress retroaction from pulsations generated on the mains when supplying energy to a single phase grid. Hereby the electrical efficiency of the power converter is increased. Also, an active snubber circuit is described which further increase the efficiency.

There have been problems in that a dedicated apparatus is needed for a conventional method of manufacturing an organic thin film transistor and in that: a little amount of an organic semiconductor film is formed with respect to a usage amount of a material; and most of the used material is discarded. Further, apparatus maintenance such as cleaning of the inside of an apparatus cup or chamber has needed to be frequently carried out in order to remove the contamination resulting from the material that is wastefully discarded. Therefore, a great cost for materials and man-hours for maintenance of apparatus have been required. In the present invention, a uniform organic semiconductor film is formed by forming an aperture between a first substrate for forming the organic semiconductor film and a second substrate used for injection with an insulating film formed at a specific spot and by injecting an organic semiconductor film material into the aperture due to capillarity to the aperture. The insulating film formed at the specific spot enables formation of the organic semiconductor film with high controllability. Further, the insulating film can also serve as a spacer that holds the aperture, that is, an interval (gap) between the substrates.

The present invention provides a fuel feeding apparatus and method for improving the controllability of mixing process and mixing ratio of fuel and combustion air, and a combustion system and method for effecting new combustion properties. The fuel feeding apparatus of the combustion system has fuel feeding means, combustion gas extraction means, steam supply means, mixing means and fuel gas introduction means. The combustion gas extraction means extracts combustion gas of a combustion area therefrom. The mixing means mixes the fuel of fuel feeding means with at least one of combustion gas extracted from the furnace and steam of a steam generator. The fuel gas introduction means introduces a mixed fluid of combustion gas, steam and fuel to the combustion area as a fuel gas, and allows the fuel gas to be mixed with the combustion air. A step of mixing the fuel with the combustion gas after extracted from the furnace and a step of mixing the fuel gas with the combustion air are stepwisely carried out, so that the controllability of mixing process and ratio of the air and fuel is improved. Such a control of fuel gas flow enables control of characteristics of flame and production of flame with new properties in the combustion area.

It is an object of the invention to improve the utility of an electromagnetic absorber system which is disposed in a suspension system of a vehicle and which generates a damping force by a generation force of a motor. The electromagnetic absorber system 18 is equipped with high-speed-motion responding means, thereby obviating an insufficiency of the damping force and a deterioration of the controllability in a high-speed stroke motion. More specifically, a hydraulic absorber 64 is provided in combination with the electromagnetic absorber system such that the hydraulic absorber 64 operates in the high-speed motion in which an electromotive force of the motor 68 exceeds a power source voltage Further, two motors having mutually different T-N characteristics are provided, and the two motors are selectively operated depending upon a stroke speed. Further, a variable resistor is interposed between the motor and the power source, and a resistance value of the variable resistor is increased in the high-speed motion to realize a decrease in a time constant of the motor, etc. Moreover, to cope with a large extent of unevenness of a road surface, an active stroke motion is performed by a drive force of the motor, thereby preventing the high-speed motion from being performed.

A simple yet effective and robust identification method is presented using process step responses for process identification that can provide a continuous transfer function with time-delay without iteration. A cascade relay provides accurate and reliable more points on the process frequency response. The internal model principle is employed to design single-loop controller of PID or high-order types with best achievable control performance for controller tuning, e.g. both single and multivariable cases are covered. The process identification and control design portions can be easily integrated into a control system auto-tuning package. Further, a general control scheme for disturbance rejection is given which can significantly improve disturbance rejection performance over conventional feedback systems with time delays. Practical issues such as noises, real-time implementation and tuning guidelines are also provided. The present invention provide general, systematic, effective, and applicable methods for process identification and control for a wide range of industries such as process and chemical plants, food processing, waste water treatment and environmental systems, oil refinery, servo and mechatronic systems, where a system model is needed for analysis, prediction, filtering, optimization and management, and / or where control or better control is required for their systems.
