Title: Water treatment device
IPC: C02F9/00
Filed: 1992-03-30
Abstract: PURPOSE:To make it possible to make potable and safe water of high quality by injecting powder activated carbon into a pump for sending water to a membrane separation tank and a liquid sending line connected to the membrane separation tank, in a water treatment device composed of a coagulative sedimentation tank. CONSTITUTION:A source tap water such as river or lake water is dumped into a chemical-mixed pond 1, then a coagulant is injected into the pond using a coagulant injector 2, and is allowed to come in contact with the source tap water by rapid stirring. Next, this mixture is sent to a flocking pond 3 where a coagulated flock is formed, and this flock is allowed to precipitate and separated in a last-stage precipitation pond 4. The coagulated and precipitated water containing a fine coagulated flock which remains unseparated, is sent to a membrane separation tank 6 using a pump 5. A powder activated carbon injection point 7 is provided on a liquid sending line, and the powder activated carbon is injected into the system constantly using a powder activated carbon injector 8. A mixed liquid of coagulated flock and powder activated carbon is filtered in a cross-flow manner in the membrane separation tank 6 and separated into a highly concentrated liquid and treated water as a solid/liquid separation process.

IPC: F02D45/00
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To provide an engine electronic control device capable of almost correctly controlling a throttle by using data on the correctly communicated part even when there is an error in a part of the communicated data. SOLUTION: Desired value data is divided into superordinate four bits and subordinates four bits by an engine ECU being a transmission side to prepare data HB, LB by adding reversed data to the respective ones so as to transmit these to a throttle ECU. In the received throttle ECU, even when failing to receive the data LB, opening of a throttle valve is controlled by effectively using this as long as one bite quantity of the data HB is correctly received to thereby utilize about 94% of the desired value data. Therefore, an engine can be controlled without large hindrance, so that a harmful component in exhaust gas does not conspicuously increase and a fuel consumption rate does not remarkably get worse by the deterioration of a combustion state.
