IPC: F04D13/16
Filed: 1980-10-31
Abstract: PURPOSE: To enable to discharge water and recover the discharged water  promptly, by effecting supply of air through combination of an air tank and a jet pump mechanism in an air feeding apparatus for a pressure tank type water supplying apparatus.  
     CONSTITUTION: When an automatic valve 16 is opened, pressurized water from a pressure tank 5 is ejected from a nozzle 17c via an outlet port 5a, water supply pipe 14, and jet pump 17, i.e., its driving inlet port 17b. Water thus ejected from the nozzle 17c draws water in an air tank 8 from a suction port 17a of the pump 17 and is mixed with the same. While the water passes through a diffuser portion 17d, the velocity of water flow is decreased and its pressure is increased, and then water is discharged from an outlet port 17e. Therefore, water passed through the pump 17 is carried back into a water reservoir tank 19 via the automatic valve 16 and a discharge pipe 18. When water in the air tank 8 is drawn out, a vave 11 is opened and atmospheric air is introduced into the air tank 8. By subsequent closing of the automatic valve 16, pressurized water in the tank 5 flows back toward the suction port 17a and is carried into the air tank 8.

Title: Image processor
Inventor: TANAKA KUNIO
IPC: G06T5/00
Filed: 1995-05-26
Abstract: PURPOSE:To provide an output of an image density signal with fidelity to an original by discriminating a state of a notice picture element of the original in multi-stage between gradation images from a binary image, selecting a density conversion curve depending on the result of discrimination and applying density conversion to each picture element to reduce a sense of incongruity of the density of an outputted image. CONSTITUTION:Notice picture element signals di-1, j-5 from a line memory 2 are converted into a density signal by a density conversion circuit 3 and the resulting signal is outputted. In this case, an edge detection circuit 27 calculates the sharpness of the edge of the density of a center picture element based on picture element signals of a center picture element and adjacent picture elements of an area in the vicinity of the notice picture element and compares the result with a threshold level and three stages of sharpness signals are fed to a characteristic discrimination circuit 28 via delay circuits 8, 9, 26. The circuit 3 selects a conversion curve for a binary image signal and a conversion curve for a multi-value image signal based on the result of discrimination of the circuit 28 to convert the picture signal into a density signal. A sense of incongruity due to a rapid change in the density of an output image through the multi-value processing is reduced and an image with fidelity to an original in which thin lines, characters and gradation images are in existence in mixture is obtained.
