Patent EP-0304526-A2 (EP)
Inventor: SAITO TAKESHI
IPC: G05D17/02
Filed: 1987-11-25
Abstract: A description is made of an electric actuator for a control valve for fluids. The acuator according to the present invention utilizes an induction motor to control the degree of opening of the valve and is provided with a control system which determines the deviation of the actual opening degree from the demand opening degree, generates a valve opening or closing speed command in accordance with the opening deviation, determines the deviation of the actual opening or closing speed from the command speed, generates a torque command in accordance with the speed deviation, and computes by means of the vector computing method the primary current to be supplied to the induction motor to enable the induction motor to output the required torque. When the valve is in the fully closed position, the control system stops the supply current to the induction motor and activates a braking device which locks the motorshaft to prevent reverse rotation of the motorshaft due to load reaction. The actuator has a means of re-starting the induction motor to optimize the thrust load should any change occur in the level of thrust acting on the valve rod. The actuator is furthermore provided with a means of diagnosing whether any abnormal performance is due to wear and/or deterioration of the induction motor, of the torque transmitting system or of the valve body.

Abstract: A focus detection system detects an in-focus position of a photographing lens on the basis of a phase difference between image signals produced from two focusing portions of an image sensor for focusing an object image, the image sensor being scanned at least two times to produce first image signals corresponding to the object image from a first scanning cycle and second image signals corresponding to the object image from a second scanning cycle of the image sensor. A detector is provided for detecting maximum and minimum values of the first image signals produced from the two focusing portions obtained in a first scanning cycle of the image sensor. A signal converter converts signal components of the second image signals falling within a range of the maximum and minimum values detected by the detector into digital signals, the second image signals and the signal components being obtained in a second scanning cycle of the image sensor. A processor is responsive to the output from the signal converter for calculating the in-focus position of the photographing lens based on a phase difference between the image signals produced from the two focusing portions of the image sensor in the second scanning cycle, and the lens is moved to an in-focus position responsive to the output of the processor.

Abstract: Switching regulators for an inductive load (L, RL), having a series circuit, connected between the two pins (VC, VE) of a voltage supply source (B), having the inductive load (L, RL), a current sensor (RS), and a controllable switch (S), whose switching state is influenced by the output signal of a comparator (K), which compares the sensor signal with a reference signal, determining the nominal current value, of a reference signal source (Q, RR) and then causes the switch (S) to change over in each case when the sensor signal reaches the reference signal value, and having a freewheeling circuit with a freewheeling device (FL) connected in parallel with the inductive load (L, RL). In this arrangement, the current sensor (RS) is also arranged in the freewheeling circuit and the reference signal source (Q, RR) is controllable and can be switched over between a high reference signal value (on the reaching of which by the sensor signal, the comparator causes an interruption of the previously conducting switch (S)) and a low reference signal value (on the reaching of which by the sensor signal, the comparator (K) causes the previously interrupted switch (S) to become conducting) as a function of the output signal of the comparator (K). The freewheeling voltage generated by the freewheeling device (FL) can be changed over between a low and a high value. <IMAGE>

Abstract: A immunoaffinity method for purification of Hepatitis B surface antigen (HBsAg) using monoclonal anti-idiotype (anti-Id) as a specific eluent, is described. Ammonium sulfate fractions of Hepatitis B surface antigen (HBsAg) containing plasma were adsorbed on monoclonal idiotype (Id) immunoadsorbents. Bound material was eluted from the column with the anti-Id of HBsAg. The eluate, contaminating anti-Id, was further purified by gel filtration. The procedure yielded highly purified HBsAg. The final HBsAg Product was free from contaminating humen plasma and mouse ascite proteins. The procedure is generally applicable and particularly attractive when the antigen is unstable in commonly used eluting conditions.
