Title: Fluidized bed type waste water treatment method and apparatus
Inventor: TOMITA YOSHIO
IPC: C02F3/08
Filed: 1989-08-25
Abstract: PURPOSE:To stabilize the treatment of waste water in a fluidized bed type treatment apparatus by controlling the fluidized state or air bubble amount in a cylindrical tank body by the adjustment of the air diffusion amounts from both of primary and secondary air supplying diffusion apparatuses. CONSTITUTION:An air diffusion apparatus 8 for supplying secondary air is also arranged to the lower part of the second water channel 4 and the waste water falling in the second water channel 4 is aerated by a controlled amount of air. The flow velocity, granular carrier fluidizing state and air bubble amount in the tank 1 are determined by the balance of the primary air amount of an air diffusion apparatus 6 for supplying primary air and the secondary air amount of the air diffusion apparatus 8 for supplying secondary air. Therefore, the second water channel 4 is merely used as a sedimentation tank conventionally but, in this method, the rising stream in the first water channel 3 can be controlled to gentle flow by the secondary air amount and a fluidized bed can be also formed in the second water channel 4.

Title: Waste gas heat recovery equipment
Inventor: SUZUKI MITSURU
IPC: F28F27/00
Filed: 1985-10-02
Abstract: PURPOSE:To maintain high corrosion-resistant properties over a long time, and to easily recover heat from waste gas in a sanitary installation and others, by adopting a heat transfer pipe on which metallic inner surface a resin layer is formed, and on which outer surface a lead layer is formed, and by providing a temperature controlling mechanism for feed water to be fed into the heat transfer pipe. CONSTITUTION:Heat is recovered by supplying a heating medium such as water, for example, through a heat transfer pipe 5 which is provided in a heat exchanger part 4, when a waste gas is passing through a waste gas flow path 1. Usually the temperature of the waste gas flowing through the waste gas flow path 1 is 280-200 deg.C when the gas is from a sanitary installation, and the temperature of the water flowing through the heat transfer pipe 5 is set at about 60 deg.C. In this case, the outer surface of a heat transfer pipe 5, which is in contact with waste gas, is formed of a lead layer 8, so that excellent corrosion resistance can be expected even if sulfuric acid or fluorine is contained in the waste gas. While the inner surface of a heat transfer pipe 5 with which water is in contact is formed of a resin layer 7, so that it serves to prevent the temperature of the heat transfer pipe 5 from lowering below the dew point of hydrochloric acid, preventing the pipe 5 from being corroded by hydrochloric acid.

Title: Engine control device
Inventor: HARADA YASUHIRO
IPC: F02D23/00
Filed: 1990-08-21
Abstract: PURPOSE:To permit crews on a vehicle to get rid of a sense of incongruity by controlling control gain in open/close control for a throttle valve when a throttle condition is switched over to an accelerating control condition. CONSTITUTION:A control unit 40 permits a throttle control condition to be switched over to an accelerating control condition when an engine is in a high loading/high speed operating condition while throttle control is being assumed. In switch-over from throttle control to accelerating control, control gain in the control of drive signals Cb as throttle control to an actuator 21 is gradually reduced, and control gain in the control of the drive signals Cb as accelerating control to the actuator 21 is concurrently increased. By this constitution, the running condition of a vehicle or the operating condition of an engine is prevented from being abruptly changed, it is thereby possible to prevent crews on the vehicle from feeling a sense of incongruity.
