AbstractAbstract
[en] We investigated the inhibition by chromate ions of the localized corrosion of aluminum by electrochemical transient measurements. In agreement with other work, the measurements demonstrated that chromate is a cathodic inhibitor for aluminum in open circuit. The reduction of hexavalent chromium to trivalent chromium is assumed to take place on catalyzed sites of the surface. The resulting products inhibit oxygen reduction reactions at these sites, thereby retarding pitting corrosion

AbstractAbstract
[en] An ionization smoke detector is described having two ionization chambers with one of said chambers having an electrode at least partially surrounded by a conductive mesh constituting an intermediate electrode and the other of said chambers being formed between the intermediate electrode and an outer surrounding electrode of conductive mesh and a radioactive source carried by said outer electrode. The volume defined by the outer and intermediate electrodes is greater than the volume defined by the intermediate electrode

AbstractAbstract
[en] Aluminum, in a chloride containing solutions close to its pitting potential, shows vigorous fluctuations in current and potential. Measurements have been made of the freely corroding potential, and the currents between interconnected electrodes. It is shown that there is a transition in the behavior of the transients. The transition occurs when multiple active pits are present and electrochemical communication occurs between them. The major source of current and potential transients is the growth process in the active pits rather than meta-stable pitting at the passive surface

AbstractAbstract
[en] We observed continuum optical emission from carbon plumes produced by laser ablation of a graphite target. Two types of continuum emission were observed: a spiky emission just after the irradiation of the laser pulse and a delayed component observed in ambient He gas. It was shown by optical emission imaging spectroscopy and laser-induced fluorescence (LIF) imaging spectroscopy that the delayed continuum emission grew in the region where the loss of C2 was significant. This result suggests that the delayed continuum emission is originated from clustering reactions among carbon species in the plume

AbstractAbstract
[en] Nonmesonic weak decays of single- and double-Λ hypernuclei are studied on the basis of two-body baryon-baryon interactions, ΛN → NN and ΛΛ → YN transitions. The two-body weak transition is described by the combination of two processes, i.e., which are meson exchange and direct quark processes. The ΛΛ → YN transition in ΛΛ hypernucleus is complement to the ΛN → NN transition as it occurs only in the J = 0 channel, while the J = 1 transition is dominant in the ΛN → NN case

AbstractAbstract
[en] The nonmesonic decay moded of Λ in nuclear matter, ΛN → N N, and production of Λ in proton-neutron scattering, pn → Λn, are studied theoretically. The weak transition of baryon is described by the one meson exchange mechanism and the direct quark-quark interaction mechanism

AbstractAbstract
[en] The INS 160cmFM/FF cyclotron was constructed during 1954 - 1958 and its operation started in 1958. Since then the cyclotron had been used by many outside users from all over Japan as well as the INS users. The operation of this cyclotron for outside users terminated in 1982. The cyclotron was built as the first inter-university facility in Japan and it contributed greatly to development of nuclear physics in Japan. This paper reports the work which aimed to clarify the scientific activities achieved by the cyclotron by searching the scientific papers published in journals during 1958 - 1992 and the citation of the papers in the same period. The study shows that the number of publications were almost constant until the middle of the 1970s and decreased gradually since then. The total number of published papers was 426, of which 390 papers were searched for and the total number of citation was about 4000. Although the about half of the papers were published in Japanese journals, the 90 % of citation appeared in European and American journals. (author)

AbstractAbstract
[en] Flux periodicity of conducting electrons on a closed surface with genus two g=2 (double torus) is investigated theoretically. We examine flux periodicity of the ground-state energy and of the wave functions as a function of applied magnetic field. A fundamental flux period of the ground-state energy is twice a fundamental unit of magnetic flux for uniformly applied magnetic field, which is shown to be valid for a simple ladder geometry and carbon double torus. Flux periodicity of the wave functions in a double torus is complicate as compared with a simple torus (g=1), and an adiabatic addition of magnetic fluxes does not provide a good quantum number for the energy eigenstates. The results are extended to higher genus materials and the implications of the results are discussed
