Abstract: In a mail sending apparatus, an attached file generation unit generates an attached file in which an access method for a designated file is described. A mail tool attaches the attached file to a mail message to form mail data, and transmits it to a designated destination through a mail server. In a mail receiving apparatus, a mail reader extracts the attached file from the mail data received through a mail server. An attached file analysis unit analyzes the access method described in the attached file. A file reception unit accesses a file management/transmission tool in accordance with the access method to receive and display the designated file.

Abstract: A proxy server is present in the path between the client and server, and intervenes in communication therebetween. Upon receiving a request from the client according to the HTTP protocol, the proxy server specifies a server based on the request, and determines the communication protocol to be used in the communication with the specified server. If the CM protocol is determined, the proxy server generates request data suitable for the CM protocol by adding necessary information, so as to implement the request contents included in the request, and communicates with the server. The proxy server sends back the processing result based on the request to the client according to the HTTP protocol.

Abstract: An aqueous coating composition wherein fine grains coated with water soluble resin composed of three monomers are contained in aqueous medium, each of said fine grains are composed of aqueous resin of ethylenically unsaturated monomer and aqueous colloidal silica, which are coexistent each other. Therefore, the aqueous coating composition is superior in not only contamination resistance, but also waterproof and weatherproof. The paint film formed by the above aqueous coating composition is excellent in its strength. Accordingly, this aqueous coating composition is useful for a coating base of exterior type coating material.

Abstract: An anti-theft apparatus for use in a vehicle-mounted electronic component includes a removable control panel. Protrusions on a first side of the control panel engage holes in a first side of an equipment body of the electronic component and function as hinges as the control panel is rotated to a mounted position. A first electrical connector on the equipment body engages a second electrical connector on a rear surface of the control panel and a biasing member exerts a force against the rear surface of the control panel. The control panel includes a recess in a second side into which a locking protrusion of a locking mechanism in the equipment body extends. A button actuates the locking mechanism retracting the locking protrusion and allowing the biasing member to eject the control panel from the equipment body. The locking protrusion is retracted by a sliding cam or directly by depression of the button.

Abstract: When an operating unit (10) of a vehicle-mounted electronic equipment is attached to its equipment body (20), a first engaging portion (18) and a second engaging portion (24) of engaging means are engaged and the operating unit is turned around the engaging means in a direction in which the operating unit contacts the equipment body substantially completely. In this case, a releasing member (11) moves a locking member (4) to a releasing position. Under such situation, a locking portion (7) of the operating unit and a locking portion (6) of the equipment body are aligned in position. The locking member (4) is then turned to a locking position where the locking means is locked to thereby complete the attachment of the operating unit to the equipment body.

Abstract: An in-focus detecting device comprising a photo-electric converter element for converting an object image formed on the image receiving surface thereof through an image forming lens, a drive mechanism for controlling the focusing position of the lens, a focus degree detecting circuit for detecting the degree of focus in a prescribed distance measuring frame of the image receiving surface and the degree of focus outside the frame on the basis of the output signal of the photo-electric converter element, and a control circuit, responsive to the output of the focus degree detecting circuit representing that the degree of focus in the distance measuring frame is below a prescribed level, for comparing the degree of focus in the distance measuring frame with the degree of focus outside the frame to determine the direction of the image forming lens to be driven.

Abstract: A process for producing an optical element wherein an optical molding is formed by using a mold and thereafter released from the mold by supplying a gas to the boundary between the mold surface and the optical molding. In the process, no localized external force is applied to the optical molding during the release thereof, and therefore undesirable deformation or flaws of the optical molding are not caused.

Abstract: An optical element whose focal length is variable comprises a medium whose refractive index is variable by temperature, a heating device for imparting heat to the medium to cause an index gradient resulting from a temperature distribution to be created in the medium, and a device for controlling the amount of heat imparted to the medium by the heating device to vary the shape of the index gradient formed in the medium.

Abstract: An optical device is composed by sandwiching a deformable member between sandwiching members. The deformable member has a shear modulus decreasing toward the inside. The deformable member may be a combination of a core and a coating with different shear moduli or a single body having a continuoudly decreasing shear modulus. The sandwiching members may be a flat plate either transparent or opaque or a lens with or without reflecting film. Because of inner soft and outer hard elastic nature of the deformable member, the sandwiching members can easily change their relative position to change an optical path and an imaging position of the optical device with good durability.
