摘要:
A method which permits the growth of high-quality crystals of n-type II-VI compound semiconductors containing sulfur, by suppressing the reaction of a group III or VII element as a dopant with a group II material at low temperature. A raw material gas containing an organometallic material of the group III or organic material of the group VII is premixed with a raw material gas containing organic sulfur material, then the premixture is mixed with a raw material gas containing an organometallic material of the group II, and the mixture is used to grow a crystal of an n-type II-VI compound semiconductor on a semiconductor substrate by a metal organic vapor phase epitaxial growth method.

A light emitting semiconductor device which emits blue and/or green light has an active layer and a pair of clad layers which sandwich the active layer (3), deposited on a substrate (1). The substrate (1) is made of GaAs, InP, GaAsP or Ge. Said active layer (3) and said clad layers (2, 4) are made of II-VI group compound semiconductor which is lattice-matched with the substrate at both room temperature and growing temperature, for instance 500.degree. C. Said II-VI group compound semiconductor has the same linear thermal expansion coefficient as that of the substrate. The linear thermal expansion coefficient of the II-IV group compound semiconductor is adjusted by additive of Cd, Mg or Hg.

摘要:
An optical logic element is disclosed which performs an XOR operation through utilization of the high-speed property of light. On each branched waveguide of a Mach-Zehnder interference type optical waveguide there is provided a phase modulating element whose refractive index undergoes a change when it is irradiated by light. The interference type optical waveguide is adapted to provide different optical output levels when the refractive index changes of the phase modulating elements are both zero or a predetermined value and when they differ from each other. Thus, the optical logic element is capable of performing the XOR or XNOR operation at an ultrahigh speed.

Provided is a pharmaceutical composition for the treatment of bulimia in which a cholinesterase inhibitor is combined with at least one member selected from the group consisting of sibutramine, a pharmacologically acceptable salt thereof, an active metabolite thereof, a prodrug thereof and a solvate thereof. The pharmaceutical composition is useful in treating bulimia and depression arising from bulimia.
摘要:
A novel antidepressant composition of a cholinesterase inhibitor in combination with a selective serotonin reuptake inhibitor, milnacipran or duloxetine is disclosed, which has a significantly high therapeutic effect as compared with conventional antidepressants. The therapeutic method using a cholinesterase inhibitor in combination with a selective serotonin reuptake inhibitor, milnacipran or duloxetine is beneficial for the treatment of depression, in particular, refractory depression.
摘要:
A transfer film comprising a base film (11), a parting-agent layer (12), a protective film (13), and a metal film (14), the latter three being formed on the base film (11) in order, wherein the protective film (13) contains a softening agent such as a phosphate, an aliphatic monobasic acid ester, an aliphatic dibasic acid ester, or a dihydric alcohol ester. By using such a transfer film, a metal back layer is formed. Since the transfer layer of the transfer film has a surface resistivity of as high as 102–108 Ω/, the surface resistivity of the formed metal back layer is high, and discharge is suppressed.
