Abstract: The object of the present invention is to provide a method of stably producing a high quality organic EL device by surely avoiding adverse influence due to organic matters and the like when an organic layer is formed on a surface of, for example, a substrate having an anode formed thereon. The means for resolution is characterized in that the inside of an organic EL device production apparatus equipped with an organic film-forming chamber for forming an organic layer on a surface of, for example, a substrate having an anode formed thereon is cleaned with an ozone gas, and the organic layer is then formed.

Abstract: An electrically-driven coarse and fine movement apparatus comprises a movable member, a driving device for driving the movable member, a first operation handle, a first rotary shaft fixed to the first operation handle, a second operation handle, disposed coaxially with the first operation handle, for rotating the first rotary shaft, a rotation restricting member for restricting a rotation of the second operation handle, which is accompanied with the rotation of the first operation handle, a rotation detector for detecting a rotational quantity and a rotational direction of the first rotary shaft, a discriminating device, linked to the second operation handle, for judging whether the second operation handle is operated or not to output a judging signal, and a controlling circuit for controlling the driving device so as to provide the movable member with a coarse movement in accordance with an operation of one operation handle of the first and second operation handles and to provide the movable member with a fi

Abstract: An electrically-driven moving apparatus for a microscope includes a control device for rotating and stopping an electric motor on the basis of outputs of a detector for detecting a rotational quantity of an operation handle and of a detector for detecting a position changing quantity of a stage. There may be provided a speed control device for changing over the stage to extremely slow fixed speed control when using an objective lens having a high magnification. The stage may be moved at a relatively high speed in response to an operation of a rotary handle for a rough movement and moved at a relatively slow speed in response to an operation of a rotary handle for a micro movement. A braking device is provided on the rotary handle, and reaching of the stage to a movement limit position can be also sensed by the operator.

Abstract: An electric revolver apparatus of a microscope comprises a revolver holding a plurality of objective lenses, a drive device for driving and braking the revolver based on a command signal from the outside of the electric revolver apparatus, a detection device for detecting a predetermined amount of rotation of the revolver and outputting a detection signal to brake the drive device, and a delay circuit for delaying the detection signal for a predetermined period of time and outputting it to the outside to delay the brake starting time of the drive device based on the command signal from the outside.

Abstract: A focus detecting apparatus of the present invention comprises (a) an image projection unit which projects a first checking light through a first region out of two regions formed by splitting a space into two along a border plane including the optical axis of the objective optical system, onto the measured object to form an image of the light source thereon, and (b) an image detection unit which condenses a second checking light emerging from the image of the light source through the second region opposed to the first region with the border plane inbetween, on a light-receiving surface of a photodetector to form image of the measured object thereon. The image projection unit comprises a first converging optical system, which has a first refractive power in a first plane parallel to the border plane, which has a second refractive power substantially different from the first refractive power in a second plane parallel to the optical axis of the objective optical system and perpendicular to the border plane.

Abstract: An electrically driven type microscope may include an interchanging device which interchanges a plurality of objective lenses, a determination device for determining which of the lenses is disposed in an optical path of the microscope, an adjusting system of which adjustment is effected during observation of a sample, a manually settable operating system for drivingly operating the adjusting system, a data recording portion for recording plural sets of manual setting information, each set corresponding to a different objective lens and containing information indicating at least one manual setting of the operating system for the corresponding objective lens, an electrical driving system for driving the adjusting system, and a driving control circuit for controlling the electrical driving system based on information from the set of manual setting information corresponding to an objective lens determined to be in the optical path by the determination device in association with an interchange effected by the inte

Abstract: A controller performs two-way serial communications between a plurality of devices at one time through a reduced number of data communication lines by use of a serial communication line and a serial port adapter connected to a CPU and an external device. The controller includes the CPU, a serial communication device constituting the adapter, and a discriminator. The serial communication device includes an interface having output and input ports, an output buffer circuit, an input buffer circuit and a data I/O terminal for transferring data. The output port is connected via the output buffer circuit to the data I/O terminal. The data I/O terminal is connected also to the input port via the input buffer circuit. A single two-way serial data communication line is thus formed. The discriminator is provided in the CPU when a specified identification code is inputted to the input port of the serial communication device, data can be received.
