Formation of SiO2-like Thin Films under Atomospheric Pressure by Vacuum Ulraviolet CVD using Ultrasonic Assisted Vaporizer

Using ultrasonicwave, we have developed a technique to support the vaporization of TEOS which is hardly vaporized by only decompression in Vacuum ultraviolet chemical vapor deposition (VUV-CVD). Mist of TEOS with the averaged particle size of 4 μm was generated by an equipment combinating a double vessel system and an ultrasonic device of which freguency is 1.7 MHz. TEOS was successfully vaporized under the room temperature and atmospheric pressure by using this equipment, and flat SiO2-like films were deposited with the VUV-CVD method, using a Xe excimer lamp(λ=172 nm). Besides, by the observation with the scanning electron microscope it was found that a number of spherical particles of around 0.6 ~ 0.8 μm in diameter were observed on the film. We have also demonstrated that the spherical particles on the film surface can be reduced by reducing the mist particles from the introducing gas material.departmental bulletin pape

Solar neutrino measurements in Super-Kamiokande-II

The results of the second phase of the Super-Kamiokande solar neutrino measurement are presented and compared to the first phase. The solar neutrino flux spectrum and time variation as well as oscillation results are statistically consistent with the first phase and do not show spectral distortion. The timedependent flux measurement of the combined first and second phases coincides with the full period of solar cycle 23 and shows no correlation with solar activity. The measured 8B total flux is (2:38± 0.05(stat.)/begin+0.16 // -0.15/end (sys.)) × 10^6 cm^{-2} s^{-1} and the day-night difference is found to be (-6.3 ±4.2(stat.)±3.7(sys.))%.There is no evidence of systematic tendencies between the first and second phases.journal articl

A chiral π-stacked vinyl polymer emitting white circularly polarized light

An optically active, pi-stacked poly[2,7-bis(4-tert-butylphenyl)dibenzofulvene] having a preferred-handed helical conformation was synthesized by anionic polymerization. A thin film sample of the polymer exhibited broad-band white circularly polarized light (CPL) emission on photo excitation.journal articl

Explicit formulas for C1,1C^{1, 1} and Cconv1,ωC^{1, \omega}_{\textrm{conv}} extensions of 11-jets in Hilbert and superreflexive spaces

22 pages. Some improvements madeInternational audienceGiven $X$ a Hilbert space, $\omega$ a modulus of continuity, $E$ an arbitrary subset of $X$, and functions $f:E\to\mathbb{R}$, $G:E\to X$, we provide necessary and sufficient conditions for the jet $(f,G)$ to admit an extension $(F, \nabla F)$ with $F:X\to \mathbb{R}$ convex and of class $C^{1, \omega}(X)$, by means of a simple explicit formula. As a consequence of this result, if $\omega$ is linear, we show that a variant of this formula provides explicit $C^{1,1}$ extensions of general (not necessarily convex) $1$-jets satisfying the usual Whitney extension condition, with best possible Lipschitz constants of the gradients of the extensions. Finally, if $X$ is a superreflexive Banach space, we establish similar results for the classes $C^{1, \alpha}_{\textrm{conv}}(X)$

補完的技術における技術選択とクロスライセンス契約(<特集>研究開発戦略・特許制度と産業組織)

本稿では, 補完的な2技術(技術AおよびB)が存在している状況下で, 複占企業がそれらの技術を選択する場合, いかなる技術選択が生じるのか, 加えて, 両企業がクロスライセンス契約を結ぶ可能性があるのか否かということを, 簡単なモデルを構築して分析する. 本稿の主な結論は以下の通りである. (1)両技術問の補完性が強い時, 技術開発を行う企業は決して技術AあるいはBだけを開発することはない. 一方, この補完性が弱い時, 技術AあるいはBのみが開発される可能性が生じ, 補完性が弱くなればなるほど, 更なる技術の開発を企図しない傾向が強くなる. (2)補完性が強い時, 開発費用が低水準でなければ, クロスライセンス契約は結ばれないが, 補完性が弱い時, 開発費用の水準が中程度であっても, クロスランセンス契約が結ばれる. しかも, 補完性が弱く場合なればなるほど, 開発費用がより高水準であってもクロスライセンス契約が結ばれる傾向が高まる.Our paper aims at investigating technology choice without cross-licensing and possibility of cross-licensing agreement by constructing the duopolistic model where complementary cost-reducing technologies (technologies A and B) can be developed. Our model is regarded as an amalgam of Mills and Smith (1996)'s model and González-Maestre (2008)'s one. Our main results are as follows: (1) If the degree of complementarities between two technologies is strong, then both firms do not develop technologies A or B solely; otherwise, then they may do so. Note that in the case where the degree is quite weak and the level of development cost is medium, they develop one of two technologies solely. (2) An increase in the degree of complementarities tends to deteriorate the cross-licensing agreement. Especially, two firms disagree cross-licensing when the degree is strong and development cost is not low.departmental bulletin pape

Expression of CCKBR in gastric adenocarcinoma cells. AGS cells have low abundance of the CCKBR, MKN45 express the CCKBR endogenously and AGS-Gr cells are stably transfected with the CCKBR. S1b.
