A method for manufacturing a toner includes a pre-mixing step and a coating step. In the pre-mixing step, a secondary aggregate of the fine resin particles is disaggregated, while toner base particles and fine resin particles are mixed and stirred using a rotary stirring apparatus. Thus obtained disaggregated fine resin particles are fixed to the surface of the toner base particle. Thus, a fine resin particle-fixed toner is obtained. The rotary stirring apparatus includes a rotary stirring section, a temperature regulation section, a circulating section, and a spraying section. In the coating step, a liquid is sprayed to the fine resin particle-fixed toner with the spraying section using the rotary stirring apparatus. Thus, a film of the fine resin particles is formed. In the pre-mixing step and the coating step, temperature regulation is conducted in the temperature regulation section.

A substrate processing apparatus comprises a multifunctional nozzle having a double-pipe structure. An inner flow path of the multifunctional nozzle is connected to a first supply suction system through a supply suction pipe. An outer flow path is connected to a second supply suction system through the supply suction pipe. The first supply suction system and the second supply suction system have respectively chemical liquid supply sources, rinse liquid supply sources, inert gas supply sources, and ejectors. Such a configuration makes it possible to selectively supply the chemical liquid, supply the rinse liquid, and supply the inert gas and suck in through the inner flow path and the outer flow path of the multifunctional nozzle.

Remote installation system and method for enabling a user to obtain any software through a communication line and automatically install it without taking a long time and requiring labor. A host computer transmits first and second key tables and to a terminal and a display displays keywords, included in these tables on a screen. The user selects keywords, which correspond to his target software, on the screen and the host computer sends a list of software, which corresponds to the keywords he selected, to the terminal. He selects his target software prom the list which is informed to the host computer. The host computer selects it from a software group and stores it on a hard disk of the terminal through a communication line, after checking its operation circumstances using a circumstance file. It is automatically registered in the system and its drive icon is displayed in a storage window. A sub-directory for a distribution destination is automatically created corresponding to the selected software thereby reducing the user's workload.

A brushless motor includes a rotor having permanent magnets and a coil for rotating the rotor. In the motor, a switching element is connected between the coil and a power source, a magnetic sensor is provided for detecting the position of one of the permanent magnets of the rotor to control the switching operation of the switching element, and a delay circuit is provided for delaying a signal from the magnetic sensor and then applying the delayed signal to the switching element.With this arrangement, the apparent hysteresis width of the magnetic sensor can be broadened and the prior art problem is avoided wherein variations in the hysteresis width of the magnetic sensor results in disabled rotation of the rotor.
