Title: Measuring method and device for external quantum efficiency of electric light emitting element
Inventor: SHIGA TAKAHIRO
IPC: H01L33/00
Filed: 2000-10-02
Abstract: PROBLEM TO BE SOLVED: To precisely measure the external quantum efficiency of an electric light emitting element by use of a small-sized device. SOLUTION: The light from the light emission part 4 of the electric light emitting element 3 on a θ-rotating stage 22 incident on a condenser 6 through a slit 5, and then incident on a multi-anode photomultiplier with filter 11 through a light mixing fiber 7. The photomultiplier 11 extends the incident light to a prescribed range by a lens 8 and selects a prescribed band by a band pass filter 9 to make it incident on a multi-anode photomultiplier 10. Accordingly, the photocurrent every wavelength can be detected by the photomultiplier 10.  The resulting photocurrent at every wavelength is corrected on the basis of the sensitivity characteristic at every wavelength, whereby the energy of the incident light at every wavelength is determined, and the energy of the incident light at every wavelength is divided by the energy of one photon at every wavelength, whereby the incident photon number at every wavelength is determined. The determined incident photon number at every wavelength is further integrated for all wavelength, whereby the total incident photon number is determined, and the external quantum efficiency of the electric light emitting element is determined on the determined total incident photon number.

Title: Molded article from cellulose powder-containing composite resin and method for producing the same
Inventor: MATAYOSHI TAKAHIRO
IPC: C08L97/02
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a molded article from a cellulose powder- containing composite resin, in which the carbonization of the cellulose powder is inhibited, the range of the possible conditions for good molding performance is widened and lubricity is imparted to the composite resin, and provide a high quality molded article from the cellulose powder-containing composite resin produced by using the method. SOLUTION: The molded article from the composite resin comprises a polyolefin (A) and a cellulose powder (B) in a ratio (by weight) of A:B of 90-25:10-75 and further comprises a lubricant having a melting point lower than the mold processing temperature in a ratio of 0.1-10 pts.wt. per 100 pts.wt. of the total of the components A and B.
