Abstract: Studies have been made for the purpose of achieving both the improvement in the storage stability of a solution-polymerized diene rubber that is modified with an alkoxysilane compound and the improvement in the physical properties of the diene rubber when blended with silica. Thus, a production method whereby it becomes possible to produce a modified solution-polymerized diene rubber having good storage stability and high reactivity with silica is developed, by introducing several tens percent of a three blanched or four blanched component that has been coupled with a tin compound into a modified solution-polymerized diene rubber, then coagulating the resultant alkoxysilane modified diene rubber with steam and then drying the coagulated product.

Abstract: A microwave detector for detecting a target microwave signal carries out detection by dividing the target bandwidth into a plurality of partitioned bands which are each repeatedly swept a prescribed number of times, with the detected wave outputs from each sweep being added together to form an added detected wave output for each partitioned band, and due to mutual cancellation of the white noise, the presence of even a faint target microwave signal within a partitioned band will increase to a detectable level in the added detected wave output of such partitioned band, and because the detection process is carried out separately for each partitioned band, the microwave detector only needs enough memory capacity to store the added detected wave output of a single partitioned band.
