Two Cases of Alveolar Cell Carcinoma and a Review of Literature.

Haigan (1970)

H Itaya S. Ishikawa F Shiratsu Masafumi OHONO Saki Hayashi

Two cases of socalled alveolar cell carcinoma are reported and hitherto reported 68 cases of alveolar cell carcinoma in Japan are reviewed.The first case that we had was 53-year-old female, who was diagnosed as the lung miliary tuberculosis at first, and so she was treated with chemotherapy. As she got worse inspite of taking chemotherapy, we performed the operation of exprolatory thoracotomy.And then we found alveolar cell carcinoma in histological examination.Our second case was 57-year-old male. He was diagnosed as the lungabscess on his right lower lung at the department of medicine.Then we performed the operation of right lower lobectomy with middlelobe segmentectomy because we recognized the small lesion in middlelobe. We diagnosed him exactly as alveolar cell carcinoma after histological examination.Even now, we have many clinical and pathological problems about alveolar cell carcinoma just because it is different from ordinary bronchogenic carcinoma.Most of the cases in Japan were found out on the autopsy but some of them were diagnosed as alveolar cell carcinoma during the operation.In general, those patients who got the operation in its early stage seemed to the better in their prognosis.Therefore the diagnosis and operation in its early stage are expected to bring out the best prognosis.

A Method of Piloting an Autonomous Mobile Robot in Dynamically Changing Environment Including Moving Obstacles

Journal of Robotics and Mechatronics (1996)

S. Ishikawa Shun’ichi Asaka

In this paper, we present a sensor-based navigation method for an autonomous mobile robot in a dynamically changing environment with stationary and moving obstacles. A navigation task needs to navigate a robot to a destination along a predefined path, and to avoid obstacles, if necessary. However, the environment is always changing, and sensory information is quite limited (actually, we have many limitations on sensory processing in connection with a dynamically changing environment). We have to describe an efficient navigation manner onto the robot using simple sensory information. The first step in our approach was to use fuzzy control. Based on results of experiments, we propose a new navigation method for an autonomous mobile robot in a dynamically changing environment. The method determines a steering angle and a velocity to be sent to a low-level locomotion system. Two major parts are involved in this operation: one is the task of tracing a planned path; and the other is the task of avoiding obstacles. The distribution weight between their outputs is determined with a range data and differential range data between samplings.

羽毛や皮膚の細菌汚染の程度が低いブロイラーを生産することが安全な食品の生産につながると考えて,ブロイラーをケージと平飼いにより育成し,羽毛及び皮膚から細菌を検出し汚染程度を比較した。実験は初夏,秋及び冬に3回反復して行った。ブロイラーの羽毛の肉眼的な汚れはケージ群が有意に低かった。皮膚1g当たりの平均一般生菌数はケージ群が103.1-105.1,平飼い群が103.8-105.9の範囲にありケージ群が少なかった。大腸菌群数は順に0-103.3,102.8-104.4,黄色ブドウ球菌は同様に0-103.1,103.4-104.1の範囲にあり,いずれもケージ群が少なかった。また,細菌が検出された検体数について両群を比較すると,一般生菌数の検出については差がなかったが,大腸菌群と黄色ブトウ球菌ではケージ群が有意に少なかった。以上の結果から,ケージによる育成により細菌汚染の程度が低い鶏肉の生産が可能であることが示唆された。

NO_x Sensing Characteristics of SiC/ZnO Heterocontact

Journal of the Ceramic Society of Japan (1994)

Yoshinobu Nakamura S. Ishikawa Ryuji Koyama Hiroaki Yanagida

The nitrogen oxide (NOx) sensing mechanism of SiC/ZnO heterocontact is investigated by thermogravimetric analysis and temperature programed desorption (TPD) of surface product on ZnO. It is known that the electric current through SiC-ZnO interface decreases by the introduction of NOx gas with water vapor in atmosphere. However, a pronounced decrease in electric current was observed only when a SiC/ZnO heterocontact specimen was sufficiently exposed to NOx with wet air. Since SiC surfaces are chemically inactive, the interaction between ZnO surface and NOx+H2O gas is thought to be responsible for the current decrease at the SiC/ZnO interface. TPD chromatogram of ZnO after exposure to NOx showed two desorption peaks which were assigned to the desorption of -NO+ and -O-N=O. When the specimen was sufficiently exposed to NOx with wet air, an additional TPD signal and marked weight-loss at around 180°C were observed. From these results, formation of zinc nitrite on the ZnO surface is suggested and it would affect the electron transfer process at the ZnO-SiC interface. In conclusion, formation-decomposition cycle of zinc nitrite or other nitrite compounds on the ZnO surface is suggested to be the origin of the reversible resistance variation of SiC/ZnO heterocontact by the introduction of NOx gas with water vapor.
