The present invention relates to a combining detection circuit for a flat panel display, which applies a combination circuit to detect the layout of a liquid crystal display thin film transistor array manufacturing process. The information processing apparatus includes an image acquiring unit, a differential region extracting unit, a designation accepting unit, and an image output unit. In another aspect, the system includes a central component for receiving the datastream in a first format, a plurality of sources in the central component, where each of the plurality of sources is associated with at least one transform, and at least one compute node coupled to the central component. Further, the reflecting mirror is bonded and fixed at the vicinities of the approximate centers of its two opposed side faces and therefore the variation in orientation of the reflecting mirror due to expansion or contraction of an adhesive is lessened, thus achieving a highly-reliable optical head excellent in environmental stability characteristics. During washing, the container can be washed reliably and efficiently while the inside of the spread out container can be visually checked by efficiently utilizing the air tight, water resistant slide fastener, liquid stirring port, liquid injecting and ejecting port, and container suspending pieces, and bottom face port fixing pieces. The ISI is determined by multiplying the average value of a transmitted discrete multitone symbol and multiplying it by the coefficients of the shortening channel impulse response in a given rotation.
