  • Publication number: 20140343241
    Abstract: The present invention provides a process for producing an ?-olefin polymer comprising polymerizing or copolymerizing (a) C3 or higher ?-olefin (s) in the presence of an olefin polymerization catalyst comprising solid titanium catalyst component (I) containing titanium, magnesium, halogen, and a compound with a specific structure having two or more ether linkages and organometallic catalyst component (II) with high catalytic activity. In this process, particularly even in (co)polymerizing (a) higher olefin(s), demineralization is unnecessary. A 4-methyl-1-pentene-based polymer obtained by polymerization using the catalyst of the present invention is excellent in tacticity, transparency, heat resistance, and releasability, and the polymer is particularly suitable for a release film.

  • Patent number: 8885165
    Abstract: A fluorescence detecting device receives fluorescence emitted by n kinds of measurement objects within wavelength bands FLk (k is an integer of 1 to n) set so that the fluorescence intensity of fluorescence emitted by a measurement object k becomes higher than that of fluorescence emitted by the other one or more measurement objects, and acquires fluorescent signals corresponding to the wavelength bands FLk (k is an integer of 1 to n). Each of the fluorescent signals is subjected to frequency-down conversion by mixing it with a modulation signal for modulating the intensity of a laser beam Lk (k=1) corresponding to at least one of the wavelength bands FLk to produce fluorescence data including the phase delay and intensity amplitude of the fluorescent signal. The fluorescence data is corrected to calculate the phase delay and a fluorescence relaxation time is calculated using the phase delay.

  • Publication number: 20140312632
    Abstract: In a vehicle door latch device, a first outside lever is pivotally mounted via a pivot shaft, and second outside lever is connected to an outside handle on an outer panel of a door via a motion-transmitting member to move toward the inside of a vehicle. Usually, turning of the second outside lever for disengaging a latch from a striker is transmitted to the first outside lever. If the second outside lever is impacted by an external force, the outer panel is deformed to move the second outside lever inward of the vehicle with respect to the first outside lever. But release turning of the second outside lever cannot be transmitted to the first outside lever. Even if the door is deformed by the external force, the door is still closed.
