Title: Cleaning method of hollow fiber membrane module
Inventor: NISHIMURA TETSUO
IPC: B01D63/00
Filed: 1994-04-25
Abstract: PURPOSE:To optimize the cleaning time, cleaning interval, and amt. of air for cleaning and to decrease the cleaning time by discharging water while the inside of the chamber is pressurized after air scrubbing is performed. CONSTITUTION:When raw water is introduced through a raw liquid supply port 3 of a porous hollow fiber membrane module, the SS component and fine particles are separated by filtering with fine pores on the surface of the hollow fiber membrane 8 and only clear water permeates through the membrane and is discharged through an exit 7. When the filtering pressure is increased, the supply port 3 is closed and an air supply port 4 and a deaerating port 5 for cleaning are opened to perform air scrubbing so as to drop the deposited matter on the membrane by vibration. Then the deaerating port is closed so that the cleaning liquid in the chamber 1 is pressurized by the cleaning air into an pressurized state. Then, a discharge port 6 is opened to discharge water.

Title: Controller for engine of vehicle equipped with automatic transmission
Inventor: SAKAMOTO KATSUHIKO
IPC: B60W10/10
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the undesirable temperature rise of the exhaust gas by allowing an intake charge quantity control means to control the intake charge quantity for a cylinder so that the output torque of an engine is reduced, when the speed change operation in an automatic transmission is detected. CONSTITUTION:When the speed change operation by an automatic transmission is detected, the intake charge quantity of the cylinder in an engine is varied, and the output torque of the engine is reduced. Since the engine output torque is reduced when the speed change operation is detected, the speed change shock due to the speed change operation is effectively reduced, and since the reduction of the engine output torque is carried out by controlling the intake charge quantity in the cylinder, not by carrying out control for changing the ignition timing in the engine to the delayed side, the control for reducing the engine output torque can be carried out without incurring the undesirable temperature rise of the exhaust gas supplied from the engine.
