    An adsorption heat pump(AHP) with pumping is proposed to expand the available heat sources and to increase cooling power. The main objective of this research is to carry out the conceptual study of operation range in points of adsorption equilibria and experimental study of desorption and adsorption processes by silica-water AHP which is composed of a mechanical booster pump(MBP) and an adsorber of packed bed. This effect is confirmed experimentally. In these experimental ranges, the amount of pump power is effective to increase cooling power. Therefore, it is confirmed that the range of temperature, which is able to use as a heat source, is expanded and cooling power is increased directly by pump power

    腎癌摘出後15年を経過し肺転移を来した切除症例

    腎癌の約70%をしめる淡明細胞癌(clear cell carcinoma)は切除から10年以上の経過の後、遠隔転移を来すことがある。今回われわれは、腎癌切除から15年目に肺転移を来し、切除した症例を経験した。術前細胞診・組織診では悪性所見は認められず、術中の迅速標本検査では淡明細胞腫瘍と診断されたが、良性・悪性の診断は付かず、免疫染色によって腎癌の肺転移と確定診断がなされた。既往歴から術中の判断で区域切除とリンパ節のサンプリングのみに留めたが、肺癌にも淡明細胞癌は存在し、切除範囲・リンパ節廓清の有無など判断に苦慮した症例であった
