Abstract: An EMI/RFI shielded printed circuit board housing of compact design suitable for computer system products (such as, e.g., bridges and repeaters) permits such products to be used on office work surfaces or in a wall-mounted, high density storage system within an office environment. The housing has a five-sided printed-circuit-board container with a back wall defining at least one window for exposing an electrical connector that requires access from the exterior of the container, a removable front cover, a removable trough-shaped rear cover for covering the container back wall and protecting the exposed connector located thereat. The back wall is equipped with support features for permitting the housing to be supported in the high density storage system during use. The container and front cover have a plurality of interior surfaces coated with an EMI/RFI shielding material. In other aspects of the invention, the housing has printed-circuit-board-support features for precisely positioning and supporting the printed-circuit-board within the housing in such a way as to avoid contact between the printed circuit board circuitry and the EMI/RFI-shielding material. In addition, the housing has a connector-access button defining a recessed interior volume into which extends a male electrical connector mounted on the printed circuit board.

Abstract: A designating mechanism generates filtering designation data, which designate the contents of filtering, reverberating designation data, which designate the contents of reverberation, and characteristics data, which express the combined contents of filtering and reverberation. A parameters generating mechanism generates filtering parameters expressing filtering characteristics, and generates reverberating parameters expressing reverberation characteristics. A readout device reads out a first operating algorithm, which designates filtering designation data, and a second operating algorithm, which designates reverberating designation data, from a memory mechanism wherein a plurality of operating algorithms are stored. A computing mechanism creates a digital filter having characteristics corresponding to filtering parameters, based on the first operating algorithm, creates an operating unit having reverberation characteristics corresponding to reverberating parameters, based on the second operating algorithm, operates this digital filter and this operating unit in a time shared manner, and processes filtering and reverberation in parallel.

Abstract: An apparatus includes a system controller which calculates a ratio of a first signal to a second signal and adjusts a control parameter of an electrophotographic reproduction process so that the density of fog indicated by the ratio is within a predetermined range. A first optical sensor outputs the first signal by detecting a reflectance of a non-image area on the photoreceptor between a developing unit and a transfer charger. A second optical sensor outputs the second signal by detecting a reflectance of a surface of the photoreceptor between a cleaning unit and a charger. The system controller controls developer including toner and carrier to be agitated when the ratio obtained after adjusting the control parameter is still outside the predetermined range. Since the density of fog is detected with accuracy by calculating the ratio, copy quality is stabilized even when temperature changes. Moreover, even if the ratio is outside the predetermined range as a result of the supply of toner which has deteriorated due to a heat history, the deterioration of toner is restored by agitating the developer. It is thus possible to prevent copy quality from being degraded.

Abstract: A fabrication method for a microstructure having a vacuum sealed cavity therein including the process steps of forming an aluminum filled cavity in a silicon substrate and heating the structure such that the aluminum is absorbed into the silicon material leaving a vacuum in the cavity. A silicon substrate (10) is coated with an oxide layer (12) which is patterned in accordance with a desired cavity geometry and an etching step is carved out by either a conventional wet or dry etch to form a cavity. The structure is covered by a layer (14) of aluminum which also fills the cavity. The aluminum layer (14) is then planarized by known techniques available in the art to produce a planar structure and then overcoated within a thin oxide film (16). Finally, the structure is heated, that is, it is sintered at a temperature in excess of 525 degree centigrade which causes the aluminum in the cavity to become absorbed by the silicon wafer and thereby providing the vacuum cavity (18) now fully enclosed in the substrate.

Abstract: A card type semiconductor device which has a main circuit board (2) equipped with primary modules such as a CPU (10) and an I/O sub-system chip (13) and a first sub-circuit-board (3) equipped with a main memory (9). The main circuit board is connected to the first sub-circuit-board through an FPC (4). Further, a first TCP (5) equipped with the CPU and a second TCP (6) equipped with the I/O sub-system chip are mounted on both of the top and bottom surface of the main circuit board in such a manner that the second TCP is placed just opposite the first TCP. The card type semiconductor device is used as a card type computer by bending the FPC and facing the main circuit board to the sub-circuit-board and enclosing the main circuit board and the sub-circuit-board in a card-shaped thin housing. Thereby, reduction in size and thickness of the card type semiconductor device can be achieved. Further, a high density packaging can be realized. Moreover, an operation of the card type semiconductor device can be performed at a high speed. Furthermore, the performance of the card type semiconductor device can be easily and most appropriately changed in a short time at a low cost without changing the primary modules only by replacing the sub-circuit-board with another circuit board.
