Abstract: Provided is a multi carrier transmission device capable of compensating the delay time and the imbalance and the orthogonal difference between the in-phase component and the orthogonal component of the amplitude at a low cost without increasing the circuit size. In this device, a coordinate conversion unit (103) performs coordinate conversion of each symbol of m-series transmission signals so as to be symmetric with respect to the I-axis or the Q-axis of the I-Q plane or a line passing through the origin and having a positive 45-degree inclination with respect to the I-axis.

Abstract: A CDMA communication apparatus wherein resistance against phase noise can be improved without degradation of transmission efficiency. In this apparatus, spread parts (110-1 to 110-n) spread the respective ones of transmission signals (1 to n). Coordinate transformation parts (120-1 to 120-n) interchange the in-phase and quadrature components of the signals as spread for each chip. A multiplexing part (130) multiplexes the n signals as coordinate transformed with known signals used for transmission path compensation. Coordinate transformation parts (250-1 to 250-n) interchange, for each chip, the in-phase and quadrature components of serial signals as outputted from a P/S conversion part (240) such that the coordinate transformations of the coordinate transformation parts (120-1 to 120-n) at the transmission end are reversed. Despread parts (260-1 to 260-n) despread the n signals as coordinate transformed by the coordinate transformation parts (250-1 to 250-n) to output reception signals (1 to n).

Abstract: A polyisocyanate having a biuret structure obtained by allowing .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl-xylylene diisocyanate, a diisocyanate represented by the general formula:OCN--CH.sub.2 --R--CH.sub.2 --NCOwherein R is a divalent hydrocarbon residue and water to react.The polyisocyanate is used in the form of the two-part type of polyurethane composition in combination with a polyol.The composition can provide coating films which excel in every physical properties required for the coating film, such as drying property, impact resistance, weathering resistance and chemical resistance, and therefore are advantageously used, for example, as a paint for automobile repairing uses, etc.

Abstract: A method for producing a fire-resistant, thermally insulating board, which comprises applying liquid hydrated sodium silicate (B) onto the inner surface of a facing material or sheet (A), spreading powdery hydrated sodium silicate (C) over the said applied surface, laying the said spread surface on(1) a facing material or sheet (D),(2) a facing material or sheet (D) applied in advance with liquid hydrated sodium silicate (B) or(3) a facing material or sheet having powdery hydrated sodium silicate (C) spread further over the applied surface of (2),implementing the heating and pressing procedure for gluing the assembly, and laminating the resulting fire-resistant board (E) with rigid isocyanurate foam (F).The fire-resistant, thermally insulating board shows reduced fusing and combustion of the rigid isocyanurate foam (F) even when exposed to flame and posseses superior mechanical properties.
