Filed: 1991-01-10
Abstract: PURPOSE:To improve the heat transfer action in a dead water area definitely formed on the downstream side of heat exchange air in a heat exchanger tube, and enhance the efficiency of heat exchanger. CONSTITUTION:The clearances s1 and s2 between the mutual ends of flits 12b of a slit group 12 positioned on the downstream side of heat exchange air in a heat exchanger tube and its adjacent slit group 12 are set in such a manner that they may be smaller than 1/2 of the diameter dimension of the aforesaid heat exchanger tube and the terminal section of the slit groups may be positioned in a dead water area formed on this down stream side. Therefore, a temperature distribution is produced in the slit groups partially located in the dead water area so that smooth thermal conduction may be carried out from a high temperature zone equivalent to the dead water are to a low temperature zone which is not located in the dead water area.

Title: Illuminating device
Inventor: FUKUZAWA NOBUTADA
IPC: G03G15/04
Filed: 1985-01-11
Abstract: PURPOSE:To prevent picture quality from deterioration or notching and to prevent the titled device from useless consumption by forming images having rectangular transmission/diffusion processing surfaces on an image carrier through a lens system. CONSTITUTION:Light flux radiated from light emitting chips 11, 12 of light emitting elements 5, 6 is irradiated to the transmission/diffusion processing surfaces 13, 14 directly or after being reflected by reflection processing surfaces 15, 16. The surfaces 13, 14 diffuse the light flux so as to light up with high brightness and also transmit the light flux so as to be used as rectangular secondary light sources. The images of the surfaces 13, 14 are formed on the image carrier 3 through lens systems 7, 8. Thus, the images of the surfaces 13, 14 are formed on the image carrier 3 and light radiated from other part hardly reaches the image carrier 3. Therefore, the light distribution on the surface of the image carrier 3 makes it possible to illuminate only non-picture areas B, C uniformly without the leakage of light to a picture area D and the areas B, C can be uniformly destaticized by controlling the positions of respective light emitting elements 5, 6 and the lens systems 7, 8 so that the areas illuminated by the light emitting elements 5, 6 are formed adjacently without any gaps.
