IPC: C02F3/12
Filed: 1978-08-31
Abstract: PURPOSE: To prevent shorting between influent foul water and aerating foul water and provided always stable purification ability by gradually aerating the foul water entering the aerating chamber from the point when it entered the separating chamber.  
     CONSTITUTION: A separating chamber 2 is segmented to a plurality of chambers 2a, 2b, 2c, the respective chambers 2a, 2b, 2c being subsequently connected from the foul water inlet pipe 7 side toward the separation side by means of flow transfer pipes 9. On the other hand, air diffusing pipes 10 are disposed in the chambers 2a, 2b, 2c. The volumes of the chambers 2a thru 2c are made subsequently smaller from the inlet pipe 7 to the separating chamber 8 to make the volume of air per fixed volume of foul water in the chamber 2a smaller as compared to the other chambers 2b, 2c so that the foul water subsequently passing through the chambers 2a thru 2c is gradually aerated. The foul water aerated slightly in this way is aerated in the aeration chamber 3, after which the foul water is discharged through discharge pipe 8.

Title: Fuel feed device for internal-combustion engine
Inventor: MORI YASUSHI
IPC: F02D41/32
Filed: 1984-05-29
Abstract: PURPOSE:To prevent the occurrence of engine stall and control displacement of an air-fuel ratio to a minimum value, by providing a means which performs injection of fuel being increased for correction to a value satisfying a fuel amount required by an engine by at least one complete injection at a specified time. CONSTITUTION:A fuel feed amount calculating means 200 calculates an optimum fuel feed amount responding to the operating condition of an engine detected by an operating condition detecting means 100. A fuel stop control means 500 stops the feed of fuel when an operating state satisfies a given stop condition. When an operating condition satisfies a given releasing condition during stop of the feed of the fuel, the fuel feed amount calculating means 200 is caused to increase a fuel feed amount for correction. The increase for correction is made to a value which satisfies a fuel amount required by an engine by one complete injection. This enables prevention of the occurrence of engine stall, and permits displacement of an air-fuel ratio to be controlled to a minimum value.

Filed: 1979-08-23
Abstract: PURPOSE: To enhance the cooling effect with a reduced amount of cooling water by a method wherein the cooling water is sprayed from a sprinkler at the upper portion toward a sprinkled-water eliminator and, simultaneously, the cooling air is fed  from below through the gaps between waterproof guide plates, in the titled heat  exchanger comprising a group of cooling pipes arranged concentrically and spirally.  
     CONSTITUTION: Water is sprayed from a sprinkling trough 19 toward a sprinkled- water eliminator 18 of packing structure, from which the water is allowed to flow in the form of fluxes onto a group of cooling pipes 16. On the other hand, the cooling air from a blower 14 in the lower portion flows between waterproof guide plates 15. In this case, the upper surfaces of the guide plates 15 are in rugged wavy shape, while the lower surfaces of the plates are arch-shaped and flat, so that the water is shielded and prevented from infiltrating into a fan 14 while air is allowed to pass between the guide plates freely. Accordingly, the cooling efficiency can be enhanced while reducing the consumption of cooling water and the size of the heat exchanger.

Abstract: PURPOSE:To sharply decrease the number of light sources by guiding light from one of the light source up to the display screen of a key top of a push switch in on state via a stationary-side light guiding body, a moving-side light guiding body in off state, and a light guiding body with a prism in on state. CONSTITUTION:When a central one of three push-switches is turned on, a moving-side light guiding body 130 is separated from a line consisting of other light guiding bodies 130 and stationary-side light guiding bodies 150. A light guiding body 140 with a prism is accordingly positioned on a straight line identical to the line consisting of other light guiding bodies 130 and the light guiding bodies 150, and accordingly light from a light source 160 is guided to the light guiding body 140 in its on state via other light guiding bodies 130 and light guiding body 150. The light is accordingly bent at a right angle by a prism 141 to illuminate a display screen 110 from its reverse, causing the light emission of the screen 110 so as to cause the light emission of only the screen 110 of a key top 100 in on state. Thus only one light source can be employed so as to light one in on state out of many screens 110.
