An objective lens (OL) according to the present invention comprises, in order from an object side, a first lens group (G) having positive refractive power, and a second lens group (G) having negative refractive power. The first lens group (G) comprises a positive meniscus lens (L) having a concave surface facing the object side, a positive lens (L) dispose close to an image of the positive meniscus lens (L), and a diffractive optical element (DOE) having a diffractive optical surface (D). The second lens group (G) is composed of three cemented lenses (CLto CL) which are configured with a positive lens and a negative lens cemented each other. When d00 denotes a distance from the object side to the positive meniscus lens (L), and TL0 denotes a distance from the object side to the objective lens rear end surface, 0.11&#x2266;d00/TL0&#x2266;0.19 is satisfied.

A confocal scanning microscope including: an objective system (second objective lensand objective lens) illuminating a sample SA with illumination light; a scanning mechanismscanning the sample SA to obtain an intensity signal; and a scanning optical systemprovided between the scanning mechanism and the objective system. The scanning optical system composed of, in order from the scanning mechanism side, a first positive lens group G1, a second negative lens group G2, and a third positive lens group G3. The third lens group has two chromatic aberration correction portions each formed by a positive lens and a negative lens or negative lens and positive lens. Glass materials are selected such that one performs chromatization and the other performs achromatization, thereby providing a confocal scanning microscope capable of correcting lateral chromatic aberration generated in the objective system in the specific wavelength region by the scanning optical system.

A monitoring device for an image forming device receives from the image forming device usage information indicating a history of manipulations by a user and reduction information indicating that the image forming device is operating in a reduction mode. When having received reduction information, the monitoring device determines the priority of maintenance work on a function the provision of which has been halted indicated by the reduction information, registers the determined priority in a management table in association, and outputs the registered reduction information and associated priority. When the received usage information indicates a manipulation with respect to a function the provision of which has been halted indicated by the received reduction information, the priority corresponding to the reduction information is determined to be relatively higher than when there is no manipulation with respect to the function the provision of which has been halted indicated by the received reduction information.

The invention realizes access authentication by a simple method using an existing hardware construction while assuring security when a user accesses a monitoring service display screen of a monitoring host from a client PC. A WEB page provided by a monitoring host apparatus is accessed from a WEB page intended for an administrator using an image forming apparatus, a device serial number of the image forming apparatus is used for authentication, thereby omitting an authentication operation using a log-in/account. Thus, problems experienced by the user or the administrator of the monitoring host in managing the log-in/account and a password are minimized.

Monitoring host apparatus, image forming apparatus, and access control method for access to their web pages

In an image forming apparatus capable of communicating with a monitoring device for monitoring the operating states of a plurality of image forming apparatuses, the operating amount of a part is detected, information about the operating amount is stored in relation to the part, and the stored information is sent to the monitoring device, the first consumed level of the part, which is calculated by the monitoring device based on the sent information, is acquired, and the acquired first consumed level is output in relation to the part. The second consumed level is calculated based on the stored information. When the first consumed level is acquired from the monitoring device, the first consumed level is output. When the first consumed level cannot be acquired from the monitoring device, the calculated second consumed level is output.

Image forming apparatus and information processing method thereof

An information processing apparatus on a network stores data in the form of albums in each of which a plurality of data are archived, and the information processing apparatus provides stored albums to communication terminals via the network in an efficient manner. The information processing apparatus detects the device type of a communication terminal and determines whether a part or all of data included in an album should be provided at a time to the communication terminal, depending on the detected type of the communication terminal. This makes it possible even for a communication terminal having low communication performance to receive data via the network without encountering an error.

Providing an album to a communication terminal via a network

It is an object to provide a zoom microscope of a simple structure which can expand a variable-power range. In order to achieve the object thereof, the zoom microscope includes a replaceable infinity correction objective lens, an aperture stop, an afocal zoom system, and an imaging optical system which are arranged in this order from a specimen side. Further, the aperture stop is disposed on or near a rear focal plane of the objective lens.

This invention relates to a service which manages data using an information processing server on a network and allows another user to browse the managed data in accordance with an instruction from a data owner. Also, this invention particularly relates to a case wherein a terminal that the other user uses to browse the managed data is a compact information processing apparatus such as a mobile phone or the like. Upon providing the managed data and appended data associated with the managed data to a terminal of the other user, the information processing server changes the appended data and a method of providing the appended data in correspondence with the performance of the terminal of the other user. For example, upon displaying image data on a mobile phone of the other user, if message information associated with that image data has a large information size and cannot be fully displayed on the mobile phone of the other user, the information processing server changes the message information to shorter information, and provides the changed information to the mobile phone of the other user. The server causes the mobile phone of the other user to display a link to full message information, and allows it to receive the message information by accessing that link.

Upon receiving a request from a communications terminal, a server apparatus performs some processes and returns processing results to the communications terminal. Before returning the processing results, the server apparatus sends the communications terminal a response containing an address needed to acquire the processing results to prevent communications from being cut off due to a communications timeout which occurs, for example, if the processing on the server takes time.
