A knife edge seal assembly includes at least one knife edge and at least one honeycomb ring seal. In the receiver, a light-transmitting medium and a photodiode are placed on the same substrate, a wavelength-selecting filter is attached perpendicularly or obliquely to the end face of or to a cut section at the midpoint of the medium, the filter transmits only the assigned wavelength included in the incident light having multiplexed wavelengths, and the PD detects only the assigned wavelength. When the unregistered character data is included, the apparatus generates new dictionary data of that character data using another dictionary and adds the generated new dictionary data to the dictionary. A protective metal shield is fastened to the substrate to protect the sensitive circuits of the image sensor from X-ray radiation damage. The delay through the clock network may drift due to temperature and supply-voltage fluctuations, which introduces phase errors in the distributed clock signals. The recycling device includes the interconnected components of a housing unit, a first door, a second door, an elongated barrel, an electrical plug, a utility motor, a utility belt drive, a rolling pin, a conveyor belt, a plurality of intake rollers, a shredding blade, a receiving bucket, a hydraulic press, a compression piston, and a control panel.
