本文では、アナログ回路を用いたフーリエ変換器の設計について報告する。古くから信号処理の領域において、フーリエ変換による短時間スペクトル分析は非常に有効な手法であり、多くの応用に利用されている。我々がすでに提案している音声認識システムも短時間フーリエ変換処理を音声波形の前処理に利用しているが、本システムでは変換後のデータクラスタリング・ラベリング部分がアナログ回路化されているため、短時間フーリエ変換器をアナログで構成することが望まれていた。本文ではキャパシタの構成をメッシュ形にしたCマトリクスを用いることにより、シンプルな回路構成でチップ面積の最小化が可能なアナログ回路による実現を示す。

A 72-year-old Japanese man was referred to a hospital because of urinary retention. Digital rectal examination revealed a stony, hard nodule in the prostate. A high level of serum PSA was not detected. Prostatic biopsy was performed, and pathological examination indicated adenocarcinoma of the prostate. He was referred to our hospital for treatment. Imaging examinations revealed no metastases (T4N0M0), so we re-evaluated the biopsy specimens. Immunohistochemical examination revealed prostatic small cell carcinoma. His levels of neuron-specific enolase (NSE) and pro-gastrin-releasing peptide (Pro-GRP) were high. We treated him with combination chemotherapy comprising irinotecan and cisplatin, and the treatment waseffective. After four coursesof the chemotherapy, levelsof NSE and Pro-GRP had decreased, and the prostatic mass had decreased in size. Needle rebiopsy of the prostate demonstrated no evidence of malignancy. Adjuvant external beam radiation therapy wasals o performed. The patient iss till alive at 18 month after diagnosis with no evidence of relapse or metastasis of the disease.

前号と本号の要約四 外国金融資本のロシア重工業征服五 帝国主義経費の負担体系と地主層の「分割統治」むすびに代えてResearch in Japan on the problem of determining the historical nature of the Russo-Japanese War has been conducted as a part of the larger problem : the establishment of Japanese imperialism. In the post-War period a far-reaching reexamination from the above standpoint has been conducted. However, it must also be kept in mind that for Russia too this war was an inevitable event in the process of formation of its own imperialistic regime. In order to evaluate accurately the significance of the war within the framework of the formation of imperialistic regimes in the international enviornment it is necessary that this problem be equally pursued from the Russian side. Thus, the first problem considered is the structure of the Russian Far Eastern policy. According to Romanov, a highly respected Soviet historian in this field, there existed among the various classes represented in the Russian Government two groups which were interested in the Manchurian enterprises and which actively encouraged their development. Romanov pointed out that these two groups were "the haute bourgeoisie who sought new markets" and "the extreemly reactionary landowning class." The author, however, questioned the method of Romanov's handling of this problem from the following two points: firstly, these two classes took opposite paths of activity in the development of capitalism; secondly, in the process of establishment of foreign policy they were not in a mutually complmentary relationship but in opposing positions. A reexamination of this class-structure has been attempted from the standpoint of determining the position of Witte's early Manchurian colonial enterprises policy within Witte's larger structure for Russian internal development. The results of such an investigation show the following: the Manchurian colonial enterprises had the significance of being a method of capital outflow for monopolistic state capital; this in particular centering upon the Chinese Eastern Railroad. As an extension of the plan for the growth of the state railroad system within Russia and in conjunction with the policy for exploitation of markets for heavy industrial products, which was a part of Witte's policy for promotion of heavy industries, these enterprises served the interests of Russian heavy industries. However, since Russian heavy industries were dominated by foreign capital, especially French capital, profits derived from them fell directly into the hands of foreign entrepreneural capitarists. The profits of the landowning class, on the contrary, were sacrificed to these foreign capitalists. Thus, it is proposed that Romanov's thesis has room for revision in the sense that the class-foundation of Witte's Far Eastern policy was foreign capital, in particular French enterpreneural capital.
