The degree of the surface roughness and the functional group on a surface after treatment were analysed by the microscope and X-PS (ESCA), respectivly. When the combination of cobalt, cupper or iron chloride and phenylhydrazine were used, carbonyl, carboxyl and hydroxyl groups were found on the rubber surface and adhesive strength showed about 10 times that of the nontreated rubber. 1996-03-30T15:00:00Z http://hdl.handle.net/11133/984 タイトル: p型Czochralski成長シリコンウェーハのDLTS評価 著者: 加藤, 勇夫; 徳田, 豊 抄録: Hole traps in boron doped p-type Czochralski-grown (100) silicon wafers have been studied by deep-level transient spectroscopy. Three hole traps of E_V+0.10eV(H1), E_V+0.42eV(H2) and E_V+0.44eV(H3) are observed. Their concentration is in the range 10^<10>-10^<13> (cm)^<-3>. Trap H2,H3 are annealed out in the temperature range 300℃-350℃. Trap H1 is probably associated iron-boron complex, since its hole thermal emission data coincide with those of iron-boron complex. However, the origins of trap H2,H3 are still unknown. 1996-03-30T15:00:00Z http://hdl.handle.net/11133/985 タイトル: 高強度RC柱の圧縮破壊時吸収エネルギーの寸法効果 著者: 小池, 狹千朗; 畑中, 重光; 水野, 英二 抄録: In the present study, the effect of specimen size on the absorption energy of RC colomns is discussed based on the reported test data of reinforced high- and ultra-high strength RC rectangular columns reported earlier by the authors and the new data of ultra-high strength RC cylindrical columns. Experimental factors include the section size of specimen (b=9.7,15,20 and 25cm for square cross sections, D=10,15,20 and 25cm for circular cross sections), concrete compressive strength (Fc=700 and 1000kgf/(cm)^2), the six types of hoops, pitch of hoops (S=∞, b/4,b/6 and b/8) and yield strength of hoops (σy=3000,5000 and 15000 kgf/(cm)^2 level). Following statements can be drawn from the test results. 1) The absorption energy up to failure Wp of RC columns increses with incresing concrete compressive strength and the magnitude of lateral confinement, which depends on the pitch, yield strength and shape of hoops. 2) Size effect on the absorption energy up to failure Wp of RC columns is rather small when the magnitude of lateral confinement is very high, or the value of Wp itself is large. 1996-03-30T15:00:00Z http://hdl.handle.net/11133/979 タイトル: 宇宙船内で回転するペンチの倒立と振動 著者: 山田, 豊 抄録: When handles of pliers are opened and they are rotated around thier symmetrical axis, with tips upward, the pliers will have several stable turns in space shuttle. Then they will flip upside down and have another several stable turns. These movements continue repeatedly. Same thing will happen to the movements of the board which is rotated around the principal axis of inertia, parallel to the surface of the board. To explain this phenomenon, the law of angular momentum conservation is very important. The former equation for this law is not accurate. Therefor, a new accurate equation is presented. By using this new equation and the law of kinetic energy conservation, angular velocity and angular acceleration for turnover and swinging of rotating object are obtained. 1996-03-30T15:00:00Z
