Abstract: A furniture unit is provided specially adapted for use in laboratories. The furniture unit includes a pair of spaced-apart uprights and vibration-dampening legs extending from the uprights for stably supporting the furniture unit on a floor surface. A belt-high structural beam comprising two opposing C-shaped beams is fixedly attached to the uprights to rigidly interconnect the uprights in a spaced relationship. A plurality of worksurfaces is provided, each having a pair of cantilever brackets configured to rigidly connect to a side of the belt-high structural beam and to extend laterally therefrom. The plurality of worksurfaces is separately adjustably supported on the belt-high structural beam for vertical height adjustment, with at least one of the cantilever brackets engaging the belt-high structural beam at a location between the uprights. Shelves are attached between the uprights above the plurality of worksurfaces.

Abstract: A furniture arrangement includes an overhead support defining an elongated overhead utility channel, and one or more lamps attached to the overhead support in recesses formed by the utility channel. A dome-shaped reflector or gull-wing-shaped light-distributing member is attached to the overhead support for distributing light from the lamps downwardly into side areas around the overhead support. The light-distributing members are positioned to both distribute light from the lamp and to visually shield contents of the utility channel from people standing around (or above) the side areas. The utility channel forms light-source recesses for receiving the lamps and lamp ballasts, and wireway recesses for receiving lay-in wiring and utilities, which wiring and utilities are guided by the light-distributing members into the wireway recesses.

Abstract: A thermosetting resin composition (a) comprising 60 to 97% by weight of a thermosetting resin containing dihydrobenzoxazine rings and 3 to 40% by weight of a novolac phenolic resin and a thermosetting resin composition (b) comprising 5 to 30% by weight of the thermosetting resin and 70 to 95% by weight of a novolac phenolic resin are cured fast, and the cured products thereof are excellent in mechanical properties and non-flammability.

Abstract: An image forming device connected to one or more data processing devices is disclosed, and includes a printer unit, a copying unit, a document transport unit for transporting documents printed in the printer unit to a document mounting unit on the copying unit, and a guide member for moving the printer unit between a first position adjacent to the document mounting unit on the copying unit and a second position separated from the document mounting unit. The data processing device sends print jobs to the printer unit, and if multiple copies are desired, the printed documents are sent to the copying unit by the document transport device and copied.

Abstract: A developing device includes a toner container for supplying toner; and a container receptacle for receiving the toner container therein. The container receptacle includes a positioning plate for positioning the toner container with respect thereto by making contact with a frontal end of the toner container in an insertion direction, and engaging means provided on the positioning plate. The engaging means has a first engaging member, and a second engaging member partially surrounding the contour of the first engaging member when viewed from a rear end of the toner container in the insertion direction.

Abstract: An electron beam emitting face (11) is exposed downward through a round hole (22) made in a support table (20) on which an electron beam irradiation unit (10) is mounted. Below the electron beam emitting face (11) a bottomed cylindrical member (60) is disposed on a performance board (24) mounted on a test head (40) with an opening of the bottomed cylindrical member facing the electron beam emitting face. A ring-shaped circuit board (53) is mounted on the upper end of the bottomed cylindrical member (60) and a ring-shaped airtight coupling mechanism (70) is provided, with the ring-shaped circuit board held between it and the bottomed cylindrical member. The ring-shaped airtight coupling mechanism (70) is airtightly connected to the support table to hold vacuous a space opposite the electron beam emitting face and the inside of the bottomed cylindrical member (60).

Abstract: An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped.

Abstract: It is a major object of the present invention to break down and level a heap-up of toner built in the hopper through dropping from the cartridge when feeding toner into the hopper and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper.

Abstract: An electrostatic latent image-developing device is equipped with a toner cartridge-holding means and a toner cartridge fitted thereto. The toner cartridge includes a container with a toner discharge openings, a toner contained in the container, and a sealing means for sealing the toner discharge opening. The sealing means is constituted by a tape member that is provided to move across the toner discharge opening, and a toner passage opening is formed in the tape member. The toner discharge opening is opened when the tape member is so moved that the toner passage opening is positioned at the toner discharge opening. The toner cartridge-holding means includes a hoist frame that moves up and down, and the toner cartridge is held in this hoist frame.

Abstract: An image forming apparatus which facilitates the input and output of copy paper. One embodiment includes an image forming apparatus with paper supply trays, a development area, a console and a sorter. By pressing a transparent paper mode key on the console, normal and projector paper are sequentially fed from the trays to the development area and then to the sorter. The sorter is set in one of three modes by a sorter instructor. A manual key on the console allows an operator to set the instructor to position the sorter in any one of the three modes. The pressing of the transparent paper mode key or the detection by a detector of transparent paper in the feeding tray results in the instructor setting the sorter in a non-sort mode despite the sort instructor having been previously set in a different mode.
