Abstract: A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station (200) incorporating this wireless receiving apparatus, a selecting part (205) selects a plurality of the same symbols in accordance with a mapping pattern established at the time of generating OFDM symbols in a base station. 
A correlation value calculating part (207) determines correlation values between the subcarriers of the same symbols to generate an R-matrix, and further determines an inverse matrix of the R-matrix. An MMSE processing part (208) performs an MMSE processing to determine a weight (W) from both a P-vector received from a channel estimating part (206) and the inverse matrix of the R-matrix received from the correlation value calculating part (207). Multipliers (209-1 to 209-N) multiply each of the symbols selected by the selecting part (205) by the weight determined by the MMSE processing part (208). 
A combining part (210) combines the symbols as multiplied by the weight.

Abstract: A conveyor device configured in such a manner that, in order to reduce pulsation of the horizontal travel speed of a chain of the conveyor device, the chain is driven by a sprocket. The conveyor device is provided with a guide for guiding pins of the chain. The guide surface of the guide guides the pins along the trajectory of the intersection between a radial line passing through the center of a sprocket groove and a circular arc having a radius which is the distance between first and second pins of a certain link. At the entrance portion of the guide, a pin is received at a position on the pitch circle of the sprocket, and then the pin is moved to a position outside the pitch circle in the radial direction to suppress rocking of a step and pulsation of the chain. Pulsation of the conveyor device using the chain can be suppressed.

Abstract: A main control section 92 determines a shift speed that cannot be established, and sets a shift speed that can be established to output a solenoid command signal to a drive circuit (an SLT circuit 98a, an SL1 circuit 98b, an SL2 circuit 98c, an SL3 circuit 98d, an SL5 circuit 98e, an S1 circuit 98f, an S2 circuit 98g) corresponding to a solenoid valve SLT, SL1 to SL5, S1, S2 corresponding to the set shift speed. A monitoring section 94 determines an abnormality in the main control section 92, and blocks transfer of the solenoid command signal from the main control section 92 to the drive circuit and outputs an on signal to the S2 circuit 98g for a second on/off solenoid valve S2 to establish a neutral state when it is determined that an abnormality is occurring in the main control section 92. Thus, any abnormality in an automatic transmission or a control device for the automatic transmission can be appropriately handled using the main control section 92 and the monitoring section 94.

Abstract: A method for concluding the operation of the continuous casting of strip metal comprising the steps of casting said strip in a narrow slotted strip shaped continuous casting mold having a flared inlet pouring zone necking down to a distal zone in which the walls of the mold are parallel and spaced apart by substantially the desired cross-sectional shape and dimensions of the strip being cast, pouring liquid metal through a pouring tube having an orifice into said flared zone, and controlling the pouring rate thereof, continuously detecting and monitoring the instantaneous surface level of the metal bath in said mold, withdrawing the casting from the distal end of said mold, and controlling the rate of withdrawal, adjusting the pouring rate and withdrawal rate so that the level of the metal bath is at a maximum height for said mold when in normal operation, continuously sensing whether or not there is present downstream of said mold evidence of the liquid core of said cast strip, reducing the pouring and withdrawal rates for concluding the casting to a rate at which the liquid core of the cast strip is near to but downstream of the mold and at which the metal bath level remains constant, terminating said pouring while continuing said withdrawal, whereby the metal bath level descends rapidly toward the neck end of said flared zone, reducing the withdrawal rate when the metal bath level is close to the lower end of the flared zone to a rate at which the upper surface of the metal bath can congeal sufficiently for further processing downstream by the time it reaches the end of the distal zone, and thereafter withdrawing the casting.
