Abstract: Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.

Abstract: A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

Abstract: A process for producing a soybean milk and soybean milk pack includes cooking ground soybeans with the use of superheated steam containing no or little oxygen, thus extracting soybean proteins to give a cooked bean juice of the soybeans; separating a solid soybean curd lees in the oxygen-free state without cooling the bean juice to give a soybean milk containing no or little dissolved oxygen and having soybean proteins suspended therein. The process also includes filling the thus produced soybean milk into pack containers in an oxygen-free environment with no or little dissolved oxygen without heating or cooling the soybean milk, sealing the containers, and then storing at 1 to 10° C.

Abstract: The caldron of the invention comprises a cylindrical caldron main body having a raw material charge port for charging a water-added raw material to be boiled and a discharge port for discharging a boiled raw material, both ports being disposed near to both the closed ends of the caldron main body and at least one steam injection pipe installed in the caldron main body and having a plurality of injection ports for injecting steam and preferably oxygen-free streams for boiling the raw material, wherein the injecting direction of the steam injected from the injection ports is inclined so that the steam is supplied in the circumferential direction of the caldron main body.
