Patent JP-S6394203-A (JP)
Title: Plastic optical fiber
Inventor: TANEICHI SEISHIRO
IPC: C08F6/06
Filed: 1986-10-09
Abstract: PURPOSE:To improve the durability of light transmissive performance for rays of wavelength in a near UV region by decreasing the light transmission loss of rays of 400nm wavelength to <=400dB/km and decreasing the content of a dimer which is a polymer constituting unit to <=200ppm with respect to the polymer. CONSTITUTION:A core component is the polymer contg. at least >=80wt% polymethy methacrylate unit and a cladding component is formed of the polymer having the refractive index smaller by >=25% than the refractive index of the core component polymer. The light transmission loss of rays of 400nm wavelength is decreased to <=4,00dB/km of such optical fiber and the content of the dimer which is the polymer constituting unit to be incorporated into the core component polymer is decreased to <=200ppm with respect to the polymer. The light transmissive performance in the near UV region near 400nm wavelength is thereby extremely improved and since the content of the dimer is low, the formation of a colored material by photodeterioration and thermal deterioration is decreased in spite of the continuous transmission of the rays of the wavelength in the near UV region. The deterioration in the light transmissive performance is extremely minimized as well.

Title: Vertical shaft mixed flow pump
Inventor: YAMADA MASAYUKI
IPC: F04D13/00
Filed: 1987-09-28
Abstract: PURPOSE:To make pumping operation performable irrespective of a suction water level by attaching a casing liner shiftably to a pump, while installing an airtight chamber in a lower part of the casing liner, and moving the casing liner via buoyancy of the airtight chamber according to the suction water level. CONSTITUTION:A casing liner 2 is movably attached to a casing 1, and, an airtight chamber 7 is formed in a bellmouth 3. Furthermore a small port 2a is installed in an axial sliding part of the casing liner 2. When a suction water lvel is in lower levels 8b, 8c than an impeller 5, sufficient buoyancy will not work in the airtight chamber 7, so that the casing liner 2 and the bellmouth 3 will go down due to their own weight. Consequently, even if this impeller 5 is rotated and control operation takes place, there is a sufficient gap between the impeller 5 and the casing liner 2, so that such a possibility that galling due to an anhydride may happen in the sliding part is preventable. The outside air is taken in from the small port 2a and thereby pumping-up of the suction water level 8b by negative pressure is preventable as well.
