Abstract: A mechanism for use in a brake or clutch for moving plate members 11, 12 in opposite directions to engage friction discs comprises one or as shown two screws 23, 24 movable by the rotation of a body member 30 threadedly engaging the screw(s). The body member 30 includes a ratchet member 32 engaged by a pawl 100 attached to an actuator ram 61: the actuator may be applied by fluid (air, steam) as in Fig. 5 or applied by (a) spring(s) and released by fluid (Fig. 7 not shown). Force multiplication is obtained between ram 61 and plate members. A detent pawl 110 also engages ratchet member 32, the pawl 110 sliding on a pin 114 along a slot 115 and being operable to engage a following tooth on ratchet member 32 for wear adjustment. A release rod 125 may be depressed to release pawls 100, 110 to cause rewinding of ratchet member 32 under the action of springs 105, 106. The screws 23. 24 are attached to pressure plates 20 for pads 16 (see Fig. 2). <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To provide a control device for a magnetic bearing easily changeable in an abnormality judging criterion by providing a digital signal processor for outputting a signal for informing abnormality of displacement on the basis of a comparing signal of a prescribed value and a digital signal. SOLUTION: A rotary body 1 is driven and rotated at a high speed by a motor 11 in a state of being supported in noncontact by a magnetic bearing. Displacement of the rotating rotary body 1 is detected by a displacement sensor 2. An analog displacement signal outputted from the displacement sensor 2 is converted into a digital displacement signal by an A/D converter 3 to be inputted to a DSP(digital signal processor) 4. The DSP 4 outputs a digital control signal for controlling an electromagnet on the basis of the inputted digital displacement signal. A D/A converter 5 converts this signal into an analog current command signal to be imparted to an amplifier 6. The amplifier 6 imparts a control current obtained by amplifying this signal to the electromagnet 7 of a magnetic bearing. The electromagnet 7 controls a position of the rotary body 1 by receiving this control current.

Title: Production of high-purity fucoidan from cultured itomozuku
Inventor: TAKO MASAKUNI
IPC: A61P31/04
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To extract and produce purely white high-quality fucoidan from cultured itomozuku, a kind of seaweed of the genus Nemacystus decipiens, by a simple and easy process. SOLUTION: Currently, fucoidan is produced from a Kombu and the like; however, since the content of fucoidan in a Kombu is low and the content of alginic acid, a polysaccharide, is high, the production process of fucoidan from a Kombu is complicated, resulting in high-price fucoidan. Moreover, fucoidan now available commercially is brown and poor in quality. Contrary to expectations, high-purity (purely white) fucoidan having a mol.wt. of 500,000 can be produced by dispersing itomozuku in an acidic soln. and stirring at room temp., though itomozuku contains alginic acid in a high content (1.5 times that of fucoidan). Because of the brown color, very low purity, and high price, a commercially available fucoidan is limited in its application; therefore, the production of high-quality fucoidan raises the value added.  For producing purely white high-quality fucoidan, the use of a freeze drier is the most important.

The photosensor 7 detects only the light emitted by the LED 11, while that 8 detects the light from the LED 10. Also, in reading an original 5, all the lights from the LEDs 9-11 are shielded, hence the sensors 7, 8 comes not to detect any light. Therefore, by the presence/absence of the detection of light by the photosensors 7, 8, the size and the direction of an original can be identified.

Title: Phase control device for thyristor rectifier

IPC: H02M1/08
Filed: 1988-02-22
Abstract: PURPOSE:To improve reliability, by alternately setting the fixed value and the variable value in a time counting means with respect to the constant control of a pulse interval of a thyristor rectifier. CONSTITUTION:In a phase control device, by a count-UP signal C at firing time an interruption takes place in a CPU 1 and a phase control operation means A is started. At the same time, by the count-UP signal C output data D of a data latch 2 is recorded in a counter 3. The output data D then is thetafix (fixed value) set by a phase control operation means B. The counter 3 decreases this data thetafix in synchronization with the clock. The phase control operation means A finds the next firing time by operation and sets thetavar (variable value) to the data latch 2. As the above operation means B is started by the count UP signal C produced by counting from the firing time, the output data D is input into the counter 3. By repeating these processes, a firing pulse signal is generated.
