Abstract: PROBLEM TO BE SOLVED: To obtain a PWM control apparatus by which an output voltage can be controlled continuously, so as to be faithful to an instantaneous voltage command when a dipolar modulation and a partial dipolar modulation are used as the PWM control of a three-level inverter. SOLUTION: A bias-adjusting means is installed, in such a way that it is provided with a means by which fundamental modulated waves are divided into a positive instantaneous voltage command abp, used to generate positive output voltage pulses and into a negative instantaneous voltage command abn, used to generate negative output voltage pulses on the basis of a set bias amount and that the bias amount is adjusted in a period, in which the absolute value of either the positive instantaneous output voltage command or the negative instantaneous voltage command becomes a prescribed value or lower, i.e., a modulated-wave detector 24 which detects the absolute value is installed. Modulation-percentage, corresponding data 25 which is used to create a minimum on-pulse width decided by the characteristic to a switching element, is installed.  A gain regulator 27 which finds a compensation gain according to the difference between the absolute value, and the modulation-percentage corresponding data is installed. A judging device 29 which judges modulation percentage used to create the minimum ON-pulse width is installed. Thereby, a bias compensation amount is computed.

Abstract: PURPOSE: To simultaneously specify desired plural memory blocks in accordance with a situation and to shorten erasing time and the like by enabling selecting combination of selecting signal lines. CONSTITUTION: A row decoder 2' receives a signal NN externally specifying the number of memory blocks constituting an erasing unit other than row address signals A4 -A7 and a control signal CTL, and inputs it to a block numbers setting circuit 25. When the CTL indicates erasing, each pair of signal A4 '-A7 ' is generated in accordance with NN based on the signals A4 -A7 , and they are converted to word signals WL1-WL6 through NAND circuits LA1-LA16, NOT circuits LB1-LB16, and transistors LC1-LC16. One of any word signals is selected when performing read-out and write-in, and in the case of erasing, only NN numbers are simultaneously selected, and memory blocks of NN pieces are specified as an erasing unit.

Title: Rotary brake by electroohydraulic pressure
Inventor: PATORISU SHIYARURA
IPC: F16D57/06
Filed: 1980-04-15
Abstract: An electrohydraulic rotary brake comprises an inner core, at least one energizing winding, a cylindrical amagnetic insert and an annular part outside the core and the insert. A cylindrical bore is excentric with respect to the cylindrical peripheral surface of the insert, recesses being provided with magnetizable sliding vanes and a brake fluid. On a rotary shaft, are mounted lateral flanges in fluid-tight manner, the inner core being fast to the rotary shaft and to the insert, all three being arranged so as to constitute a rotor for the brake. The annular part outside the core and the insert constitutes an annular stator to which the lateral flanges are fixed and with the bore excentric with respect to the peripheral surface of the insert constituting the outer part of the rotor. The recesses are formed in the cylindrical amagnetic insert and extend radially therein on both sides so that the vanes are movable between a position of complete freedom of the rotor with respect to the annular stator, in which they are positioned close to the rotor core, and a braking position in which they are positioned close to said annular stator, so that, under the effect of a variation in a pre-determined sense of the current passing through the energizing winding, the vanes can be attracted towards said stator and thus define peripheral chambers of different volumes which, by the forced passage of respective volumes of fluid from one chamber to the other, cause between the vanes and the stator a severe throttling and thus the braking torque of the rotor.

Title: Crystallizing device
Inventor: KONRATSUDO SHIERUMUTSUKII
IPC: B01D9/00
Filed: 1982-03-29
Abstract: A crystallizing apparatus particularly for use with undercooled melts. Crystallizing is effected on the cooling conveyor belt in a thick layer. A precrystallizer comprises at least two rolls arranged above the cooling conveyor and rotating in the same direction. A shear gap is formed between the at least two rolls. A melt is applied to an uppermost one of the at least two rolls in a thin layer. In the course of the path followed by the melt over the at least two rolls, shearing forces are generated within the area of the shear gap, which enhance the nucleation. A further enhancement of nucleation is obtained by cooling the at least two rolls, so that relatively large volumes of the melt may be crystallized per unit time in the crystallizing apparatus without the need for the addition of supplemental seed crystals to the melt. The amount of melt in the precrystallizer is very small.
