IPC: H02M7/537
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To avoid the instability of the control in a current region in which the polarity distinction of a real current is difficult by a method in which a switching means by which a signal inputted to a selective circuit is switched to the output of a polarity distinguisher or the output of a dead-time setting circuit is provided. SOLUTION: While a regenerative current is having a positive value is larger than the set value L50 of a changeover level setting device 21 or while a regenerative current is has a negative value, the contact of a changeover switch 23 is set to a (1) side and a polarity distinguisher 17 distinguishes the polarity of the regenerative current is and the polarity distinction signal is inputted to a selective circuit 18. Therefore, if the polarity is positive, a gate device 18a is operated to select a transistor Tr1 and, if the polarity is negative, a gate device 18b is operated to select a transistor Tr4 .  If the regenerative current is having a positive value is smaller than the set value L50 of the changeover level setting device 21, the contact of the changeover switch 23 is switched to a (2) side and hence the output of a dead-time setting device 15A is inputted to a selective circuit 18.

CONSTITUTION:A character string to be searched is stored in a main memory 32 together with zero added to the end of said character string. The information on the gathering of character strings to be searched is stored in a node value field 12 and a master node identifier field 13 of an associative memory 1 and an output memory 2 after conversion into the value of a tree structure table. Then zero is set to a searching register 4 with the single head character of the searched character string set to a searching register 3 respectively. As a result, he memory 1 works and a node identifier of the coincident node is obtained in an output register 5. Then the next searching character string is checked and it is decided that the contents of the register 5 are equal to the desired character string identifier as long as the value of said next searching character string is equal to zero. While the contents of the register 5 are shifted to the register 4 if the value of said character string not equal to zero. Then the next searching characters are set to the register 3. These processes are repeated.

Filed: 1983-12-26
Abstract: PURPOSE:To reduce power consumption and to diminish the heat generation amount of each section by reducing the pulse width of a locking current at a stop signal generating time. CONSTITUTION:When a microcomputer 16 outputs a stop signal, a transistor 24 becomes ON, and a transistor 21 becomes ON. Accordingly, the output (b) becomes high. Thus, the output (a) of a sawtooth wave generator 26 is superposed on the output (b), and the level of the output (c) of an amplifier 28 becomes high. On the other hand, a reference voltage (e) is generated from an amplifier 33 by the output from the microcomputer 16, and applied to a comparator 32. A transistor 13 is conducted by the output of the comparator 32. Thus, the pulse width of the locking current (f) flowed to a motor winding 12 is extremely low, and the power consumption becomes small.

Title: Substrate delivery apparatus, apparatus and method for manufacturing device
Inventor: ITO HIROHITO
IPC: G03F9/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a substrate delivery apparatus in which a servo gain is increased, in which the servo rigidity of a temporary support part is increased and in which a delivery deviation is reduced by a method wherein the position servo gain of the temporary support part is changed depending on whether the temporary support part holds a wafer or whether the temporary support part does not hold the wafer. SOLUTION: A temporary-support-part changeover valve SVT is opened to the side of a negative pressure, and a wafer hand WH is lowered to the X-direction at a sufficiently slow speed in such a way that an arrangement deviation is not generated. Then, the backside of a wafer W becomes a height which is equal to a temporary support face TCS at a temporary support part TC, and the wafer W is supported by the temporary support part TC. At this point, the servo gain (Gq) of a servo control device QMC is changed to a gain for wafer mounting. Then, a ceiling plate Z is raised to the Z-direction until a suction force WCS becomes higher than the backside of the wafer W. When a desired pressure is reached, the temporary-support-part changeover valve SVT is opened to the side of atmospheric pressure.  When the suction force WCS becomes a height which is identical to the backside of the wafer W in a halfway part, the servo gain (Gq) of the servo control device GMC is changed to a gain for wafer non-mounting.
