Abstract: An object of the present invention is to provide a wheel drive device capable of suppressing a temperature increase in an electric motor and a power conversion device and suppressing occurrence of a failure of an electric component. Provided are: an electric motor having a stator 60 and a rotor 40; a stator holder 80 that holds the stator 60; a power conversion device 100 that converts power supplied to the electric motor; and a wheel which accommodates the electric motor, the stator holder 80, and the power conversion device 100 on the inner peripheral side. The stator holder 80 includes a flow path 90 through which a cooling medium flows. The flow path 90 is arranged between the stator 60 and the power conversion device 100.

Abstract: A high-frequency circuit device includes a dielectric member 1, a shielding conductor 2 surrounding the dielectric member 1, a support member 3 for fixing and supporting the dielectric member 1, and a pair of transmission lines 4 each of which is formed of a microstrip-line. Each of the transmission lines includes a substrate 6 formed of a dielectric material, a strip conductor 5, and an earth conductor layer 9. An end portion of the strip conductor 5 faces part of the dielectric member 1 and functions as a coupling probe for input/output coupling. Each of the transmission lines 4 is formed of a strip line, a mictostrip line, a coplanar line or the like, and has low-loss when connected to a circuit board.

Abstract: The improved method for treating waste gases by exposure to electron beams which comprises adding ammonia to a waste gas containing sulfur oxide (SO.sub.x) and/or nitrogen oxides (NO.sub.x) and thereafter exposing the gas to an electron beam so as to remove the sulfur oxides and/or nitrogen oxides therefrom is characterized by first mixing ammonia gas uniformly with air, then forming a homogeneous gas-liquid mixture from said gaseous mixture and water, and spraying said homogeneous mixture into a reactor. Efficient desulfurization can be realized even if the temperature of the waste gas being treated is fairly high at the exit of the reactor and the concentration of ammonium sulfamate in the by-product ammonium sulfate can be reduced.

Abstract: In an electronic mail associated type computer system network equipped with a computer system for executing a job and a general-purpose electronic mail system, a user of an electronic mail can freely recognize a condition of an execution result of a job performed in the computer system and a job execution result. Also, these results are available from a desired output device for the user. When a mail processing unit employed in the computer system analyzes a mail statement about the job execution derived from the electronic mail system, and the job execution is completed, this mail processing unit sends to the electronic mail system, such a mail statement for the completion of the job execution containing information about fail/safe execution result. Upon receipt of this report, the user designates the output device into a response mail so as to output the job execution result from the designated output device.

Abstract: In an arrangement of a mail terminal 1, an electronic mail system 2, a job control terminal 4, and a computer system 3, a user makes a proposal of a file operation via a mail by way of the mail terminal 1. The electronic mail system 2 stores therein the proposal mail, exchanges this proposal mail with the job control terminal 4, and furthermore distributes a file operation result to the respective mail terminals. The job control terminal 4 receives a mail from the electronic mail system 2, and interprets the proposal mail, thereby executing a conversion from a mail ID into a host ID, a judgement of an access authorization with respect to the designated file, and a production of an instruction to the computer process system 3. Furthermore, an execution host computer is selected by monitoring operation conditions of the host computers.

Abstract: A job control terminal creates a unit configuration table indicating the configuration of units connected to each of a plurality of processors in a multi-processor system. The job control terminal also creates an operating state table indicating an operating state of each processor including a CPU using ratio, I/O using ratio, memory using ratio, response time, and so on. When the job control terminal receives electronic mail for requesting job execution from a user through an electronic mail terminal, the job control terminal selects a processor assigned to execute the requested job based on the unit configuration table and the operating state table. When it is determined from the states of the processors that the requested job cannot be executed, information indicating that the job is unacceptable is transmitted from the job control terminal to the electronic mail terminal.

Abstract: A process for desulfurization and denitration of waste gas by multi-stage electron beam irradiation and an apparatus used for the process are constituted so that the waste gas is passed through the electron beam irradiation zones in multiple irradiation chambers that are arranged in such a way that the center-to-center distance (m) between two neighboring electron beam generators is not shorter than distance X calculated by the formula, X=2.alpha.+tV wherein 2.alpha. means distance over which an absorbed dose extends into a waster gas, t means a residence time (sec.) of waste gas in a non-irradiation zone, and V stands for the flow velocity of waste gas, whereby t can be reduced to 0.01-0.5 seconds, so that irradiated energy can be utilized efficiently and a maximum effect can be obtained with a minimum expenditure of irradiation energy. Therefore, the waste gas can be treated rapidly and economically.
