Abstract: A biochip reader wherein spectroscopic information of a sample under analysis is arranged in spaces between images of the sample arranged on a biochip. The reader comprises a confocal microscope and the biochip comprises a transparent substrate to allow passage of the excitation light and fluorescent light from the sample with the excitation light being applied from the side opposite that on which the samples are arranged so that noise from dust and the like is avoided by the transmitted light avoiding contact with the dust. Another aspect is an electrophoresis system wherein different coloring material are used for each of a variety of target substances, so that the same lane and area are utilizable to concurrently detect a poly-chrome fluorescent pattern of the different targets. A confocal scanner or fluorescence imaging system is used with a plurality of filters to detect the multi-colored fluorescences of the target substance.

Abstract: A Fabry-Perot filter device for selectively transmitting three wavelength bands of infrared radiation, including a reference light band, wherein the filter device comprises a fixed mirror formed on a substrate; a movable mirror arranged opposite to the fixed mirror with a gap formed therebetween so that the movable mirror is displaced with respect to the fixed mirror by applying an external force; a fixed electrode formed on the fixed mirror; and a movable electrode formed on the movable mirror and arranged opposite to the fixed electrode wherein the movable electrode is displaced by applying a potential difference across the fixed and movable electrodes so that the width of the gap is varied in at least three steps, whereby at least three wavelength bands of infrared radiation are selectively transmitted through the filter device.

Abstract: A communication control system and method comprising, in one embodiment, a master station connected to a slave station using two redundant buses, wherein command frames having the same content are sent out to the buses and the communication process is changed depending on whether or not the contents of the command frames, when received by the a receiving station, are identical. In another embodiment, a plurality of units are connected to each bus in a multi-drop configuration, and a line length of each bus is defined so that reflected signals from other units reach a receiving unit on each bus after the transition period of a received signal at that receiving unit ends. In still another embodiment, a unit is connected to each bus and the unit is provided with a driver IC, wherein transmission data is first encoded into bit signals having a fixed number of bits, then the signals are supplied to the driver IC.

Abstract: A communication control system and method comprising, in one embodiment, a plurality of strobe signals are generated at different timings in a transmission circuit and a plurality of latch circuits equal to the number of strobe signals are provided in a receiver circuit so that data is retained in each latch circuit using the strobe signals one at a time.

Abstract: A method and apparatus for mass producing biochips quickly and easily, wherein a plurality of DNA molecules are amplified using a PCR (polymerase chain reaction) method and transcribing the amplified DNA molecule to other substrates by contact.
