Title: Filler unit for dc-ac type cooling unit
Inventor: KASHIWADA TAKESHI
IPC: F28D5/00
Filed: 1990-02-14
Abstract: PURPOSE:To reduce the cost of a cooling tower body by forming air exclusive passages through which only air passes from a suction side to a discharge side between fillers at each arbitrary interval and at least every other interval among many filler plates. CONSTITUTION:Air exclusive passages 12 through which only air passes are provided between fillers at least at every other interval among many filler plates 11. Each air exclusive passage 12 is formed under an elongated shade plate covering the upper end of adjacent filer plates 11. Remaining passages not covered with the shade plates 13 are used as passages 14 for water to be cooled. Accordingly, the air passing through the air exclusive passages 12 made intermittently contact with the water to be cooled via the filler plates 11 and is thereby to dry air which has constant absolute humidity but only temperature raised. Thus, the dry air can be produced together with air which makes direct contact with the water to be cooled in the other passages and is raised in its absolute temperature parallel in a single filler unit. Hereby the cost of a cooling tower body can be reduced.

Title: Method and device for measuring elongation strain of optical fiber
Inventor: SHINOHARA HIROMICHI
IPC: G01B11/16
Filed: 1983-03-02
Abstract: PURPOSE:To simplify the device and to measure the elongation strain of optical fiber directly, by measuring the fluctuation of the power of light emitted from a 2-mode fiber. CONSTITUTION:The power P(r, theta, z) of the emitted light from a 2-mode fiber 1 is periodically changed with 2pi/(beta0-beta1) as a period when (z) is changed, where beta0 and beta1 are propagation constants of modes. Therefore, by measuring the rotary angle of a far field pattern or a near field pattern, the change in elongation pattern can be measured. Namely, laser light emitted from a light source 2 is inputted to the 2-mode fiber 1 by an incident lens 3. The emitted light from the 2-mode fiber 1 is formed on a TV 6 as the far field pattern or the near field pattern by a light emitting lens 4 and a TV camera 5. Based on the change in the formed image, the quantity of the elongation strain is actually measured by a rotary angle measuring device.
