A wavelength-converting LED can include a light-emitting section in which an exciting element emits a blue or ultraviolet light. A fluorescent material that has a mean particle diameter D50 ranging from 5 μm to 20 μm and that can convert at least part of the light emitted from the exciting element into light having a wavelength longer than an exciting wavelength, can be incorporated into the LED. A dispersing agent with a mean particle diameter D50 not less than 1/10 of the mean particle diameter D50 of the fluorescent material is preferably incorporated in the LED. A binder base material can be arranged to contain the fluorescent material, the dispersing agent and a binder therein. The sum of the weights of the fluorescent material and the dispersing agent is preferably in the range of 20% to 60% by weight of said binder base material to prevent the fluorescent material from precipitating in the binder base material upon curing.

In a process for producing a poly(arylene sulfide) by polymerizing a sulfur source and a dihalo-aromatic compound in the presence of an alkali metal hydroxide in an organic amide solvent, the production process comprises washing a polymer obtained by the polymerization with a hydrophilic organic solvent containing water in a proportion of 1 to 30% by weight, thereby collecting a purified polymer, the content of nitrogen contained in an extract extracted by a mixed solvent containing 40% by weight of acetonitrile and 60% by weight of water from the purified polymer is at most 50 ppm on the basis of the weight of the polymer, and a poly(arylene sulfide), the content of nitrogen contained in an extract extracted by a mixed solvent containing 40% by weight of acetonitrile and 60% by weight of water from the purified polymer is at most 50 ppm on the basis of the weight of the polymer.
摘要:
A polyglycolic acid-based resin composition is formed by adding a relatively small amount of aromatic polyester resin to a polyglycolic acid resin. The thus-formed composition is provided with remarkably improved moisture resistance stability and hot-melt processability, and further improved stretchability, while retaining the excellent properties as represented by gas barrier property of the polyglycolic acid resin. As a result of stretching by utilizing the improved stretchability, a shaped product having an improved transparency can be obtained.

It is possible to calibrate a measurement system for circuit parameters of a DUT (device under test) by reducing the number of attachments and detachments of calibration kits. An error factor acquisition device includes: a first calibrator (100) connected to ports (18, 28) of a network analyzer and having a first state realization unit (120) for realizing open-circuit, short-circuit, and standard load states for the ports (18, 28) or short-circuiting the ports (18, 28); and second calibrators (200) connected to the first calibrator (100) and the DUT (400) and respectively having a second state realization unit (220) for realizing open-circuit, short-circuit, and standard load states for the ports (18, 28). The first calibrator (100) includes first connection units (110a, 110b) for connecting the ports (18, 28) to the first state realization unit (120) or to the respective second calibrators (200) while the second calibrators (200) respectively include a second connection unit (210) for connecting the ports (18, 28) to the second state realization unit (220) or to the DUT (400).

A rotary electric component includes a case for accommodating a rotary body having a cylindrical operation portion and for rotatably supporting the rotary body and a substrate having a rotation detecting means linked to the rotary body at a lower portion of the case. A guide groove whose distance from the center of rotation of the rotary body is continuously changed is formed in a bottom surface of the rotary body. The rotary detecting means of the substrate has a sliding portion fitted to the guide groove of the rotary body to slide according to the rotation of the rotary body, and outputs a signal according to a movement location of the sliding portion.
