  • Patent number: 10580669
    Abstract: After a discharge of a processing liquid is stopped, a position of a liquid surface within a nozzle can be observed. A substrate processing apparatus includes a substrate holding mechanism and the nozzle. The substrate holding mechanism is configured to hold a substrate. The nozzle is configured to supply the processing liquid to the substrate. The nozzle includes a pipe member and an observation window. The pipe member has a horizontal part and a downward part extended downwards from the horizontal part, and is configured to discharge the processing liquid from a tip end of the downward part. The observation window is provided at the horizontal part of the pipe member.

  • Publication number: 20100209841
    Abstract: The present invention provides a method for producing a toner including preparing an emulsified dispersion which contains emulsion particles by emulsifying or dispersing an oil phase containing at least a pigment and any one of a binder resin and a binder resin precursor in an aqueous medium, and granulating toner base particles by converging the emulsified dispersion, wherein the Casson yield value of the single oil phase before being emulsified or dispersed in the aqueous medium is 0.5 Pa to 20 Pa; and the temperature Tn of the emulsified dispersion in the preparation of the emulsified dispersion, the temperature Ts of the emulsified dispersion in the granulation of the toner base particles, and the glass transition temperature Tg of the toner base particles satisfy the relation Tn<Ts<Tg.

  • Publication number: 20070106776
    Abstract: For the first use of an authentication device, a remote machine makes a query of an address of a local machine to be permanently assigned to the remote machine, to which the authentication device is connected, to a management server. In response to the query, the management server determines the local machine to be permanently assigned to the remote machine and notifies the remote machine of an address of the local machine. The remote machine remotely controls the local machine specified by the address notified from the management server.
