IPC: B01D61/18
Filed: 1986-05-22
Abstract: PURPOSE:To control scales of a membrane wall by providing a guide generating a swirl around the center of a tubular membrane wall in a flow channel for the water to be treated. CONSTITUTION:A guide 9 constituted, for instance, with a spiral projection is provided to generate a swirl around the center of a tubular membrane 1A in a flow channel R1 for the water to be treated. As a result, the water to be treated flowing through the flow channel R1 for the water to be treated is turned into the swirl by the guide 9 to speed up the flow near a membrane wall 1A, and the shearing force around the membrane wall 1A is increased in proportion to the increased flow speed around the membrane wall. Accordingly, scales likely to be piled up on the membrane wall 1A cannot be piled up to control the scaling layer of the membrane wall 1A more effectively than the existing systems.

Abstract: PURPOSE:To obtain a telephone set lighting device which contains an illuminator lighting circuit which starts lighting the illuminator by means of a sensor that detects the incoming state and the talking state under a busy mode of a telephone set and a timer circuit which turns off the illuminator. CONSTITUTION:When the incoming signal of a telephone set 2 is equal to an input signal higher than a prescribed level, an incoming signal holding circuit 3 detects the corresponding incoming signal via an external sensor 1. This detecting output turns on a switch S1 of an illuminator lighting circuit 6, and therefore a current flows to a relay coil L. Thus a relay contact 7b is turned on to light up an illuminator 8. Then a call is started after the receiver of the set 2 is picked up, and the circuit 3 detects the talking signal under a busy mode via the sensor 1 in place of the incoming signal of the set 2. When no detecting output exists after the end of a call, the contact 7b is turned off to turn off the illuminator 8.

Filed: 1990-05-09
Abstract: PURPOSE:To prevent transmission of low frequency oscillations at the connection part of structure by controlling a magnetic field generated by an electromagnet according to the product of the relative displacement between a nonmagnetic cylinder and a nonmagnetic shaft, and the relative speed obtained from the differentiated displacement, and thereby controlling the level of the viscosity ratio of magnetic fluid. CONSTITUTION:The relative displacement DELTAx of oscillations between a cylinder 1 and a shaft 2 to be jointed is measured by a displacement sensor 14, and the measured value is differentiated by a differentiation circuit 9 to have a relative speed DELTAv. Then based on the product of the relative displacement DELTAx and the relative speed DELTAy at a control part 11, a current source 12 is controlled. Namely, the control part 11 controls energization of a coil electromagnet in such a manner as to make the viscosity of magnetic fluid 13 that of high viscous conditions when DELTAxDELTAv < 0, while that of low viscous conditions when DELTAxDELTAv > 0. That is by using the magnetic volume of magnetic fluid as a spring constant and by controlling increase in viscosity by a magnetic field, oscillation attenuation is made variable. It is thus possible to have an excellent joint, having resonance in a low frequency, in oscillation insulating performance as well as restraining resonance peak.
