Abstract: The present invention provides a small sized wide wave-range spectroscope with a simple structure which requires a short time to measure light for measurement over a wide wavelength spectrum. The small sized wide wave-range spectroscope has a collimator (43) for changing light for measurement (L) transmitted through a slit (41) into collimated light (L0), a plurality of diffraction gratings (44a, 44b) with different grating constants d supported rotatably around a rotational axis in parallel with the incident slit (41) and disposed side by side in the direction of the rotational axis in the optical path of the collimated light (L0), and a diffracted-light focusing members (45a, 45b) for focusing a plurality of diffracted light rays (L1 to L4) provided by the plurality of diffraction gratings (44a, 44b) by which the collimated light (L0) is diffracted, each of the diffracted-light focusing members (45a, 45b) being provided in association with each of the plurality of diffraction gratings (44a, 44b).

Abstract: A manufacturing method of a ceramic green sheet comprising steps of; forming a predetermined electrode pattern on an adhesive layer separable by being heated or an adhesive layer separable by being cured with UV of a carrier sheet, wherein the carrier sheet comprising the separable adhesive layer on one side of a base film, and forming a ceramic green sheet with a ceramic slurry on the separable adhesive layer with the electrode pattern formed thereon. The electrodes in the ceramic green sheet obtained may be formed with good patterning accuracy and the carrier sheet may easily separated after formation of the ceramic green sheet.

Abstract: A removable antitheft device inhibits theft of an aircraft and the avionics of an aircraft. The device includes a horizontal member having first and second ends. A first hook is positioned at the first end of the horizontal member. The first hook is sized to engage a first yoke shaft of an aircraft. A second hook at the second end of the horizontal member is sized to engage a second yoke shaft of the aircraft. The second hook is detachable from the horizontal member. A vertical barrier is mounted to the horizontal member and is positioned proximate to an avionics stack of the aircraft to block removal of avionics equipment from the avionics stack when the first and second hooks of the horizontal member are engaged with the first and second yoke shafts. The second hook is locked to the horizontal member after the second hook engages the second yoke shaft to prevent the second hook and the horizontal member from being removed from the second yoke shaft.

Abstract: A method and apparatus provide a direct memory access (DMA) system that transfers data between a memory in a computer system and a plurality of I/O devices. The DMA system includes at least two channels which operate independently and in an interleaved manner so that multiple DMA transfers can occur concurrently. Each channel includes a pair of buffers so that data can be transferred between one buffer and memory at a rate determined by the memory and data can be transferred between the other buffer and the I/O device at a rate determined by the I/O device. Transfers between the two buffers occur at a data rate determined by the bus connecting the two buffers. Thus, the transfers between the two buffers occur in bursts to optimize the transfer and to reduce the amount of time that the bus is needed for the transfer. Therefore, the bus is available for transfers by the other DMA channel and by other devices on the bus.
