Abstract: PURPOSE:To enhance the stopping positional accuracy for a semiconductor substrate by a method wherein a high speed rotary motor and a low speed rotary motor are equipped, then a resist is made uniform by using the high speed rotary motor, and the low speed rotary motor is used when the rotating semiconductor substrate is stopped. CONSTITUTION:A control 12 operates a drive part 7 so as to lower a rotary transmission part 5 and releases it resulting in stopping the high speed rotary motor 3, and thus makes a brake 13 work. At the point that the number of revolutions of a table 1 detected by a sensor 11 becomes 10 and several revolutions, the control 12 releases the brake 13 and operates the drive part 7, then contacts the rotary transmission part 6 with an idler contact rotary plate 6' via gears 8 and 9 resulting in the rotation of the low speed rotary motor 4, and thereafter rotates the table 1 at a low speed of several RPM. After the control 12 decides the rotation stopping position for the substrate 2 on the table 1 by the sensor 11 and stops the motor 4, the unloading of the substrate 2 is performed so as to operate the drive part 7 to release the rotary transmission part 6. When the next substrate is loaded on the table 1, above-mentioned processes are repeated.

Title: Driver for dc brushless motor
IPC: H02P6/06
Filed: 1992-03-24
Abstract: PURPOSE:To make possible to suppress increase of current under a mode having shorter time length by making one of odd number mode time length or even number mode time length shorter than the other at the time of simultaneous starting. CONSTITUTION:An interruption time correcting routine is stored in a microcomputor 7. In other words, the interruption time T is set T=0.75T' for odd number mode whereas T=1.25T' for even number mode, where T' is a conventional interruption time, thus setting the odd number mode time shorter than the even number mode time. Peak current is suppressed by suppressing current at the point of time when transistors Q4-Q6 in lower arm are turned ON (when an odd number mode is switched to even number mode) since transistors Q1-Q3 in the upper arm are chopping.

Filed: 1987-03-20
Abstract: PURPOSE:To eliminate the need of setting of a ROM only for test to a subsystem and to facilitate an operation test by not storing a testing program in the ROM of the subsystem but transferring it from a main system to the RAM of the subsystem to perform the operation test of the subsystem. CONSTITUTION:After the operation of a central processing unit 3 is stopped based on the command from a command means 1, a program transfer means 4 directly transfers a control program to a rewritable memory 5 without passing the central processing unit 3. Thereafter, the central processing unit 3 first reads out the contents of a read-only memory 6 and tries the operation when an operation stop and release means 2 releases the operation stop state of the central processing unit 3. The read-only memory 6 is set to a high impedance in accordance with the command of the command means 1 by a memory read switching means 7 to exclude an influence upon another device, and the memory read switching means 7 makes it possible to read out contents of the rewritable memory 5 instead of the memory 6. Consequently, the central processing unit 3 performs the operation in accordance with a control program stored in the rewritable memory 5.

IPC: B60B33/00
Filed: 1980-05-22
Abstract: PURPOSE: To improve a buffering property and stabilize the directivity of a caster,  by providing an elastic member, which comprises leaf springs and a coiled spring  connected in series with each other, between a steering bearing and the bearing-supported part of a moving wheel.  
     CONSTITUTION: A pair of leaf springs 3, whose butts are attached to the bottom of a bearing 2 for a steering shaft 1, are inclined back. The free ends of the leaf springs are attached to a lower seat 5 for the cover 6 of a moving wheel 7. A tension type coiled spring 4 is provided between the lower seat 5 and upper seat 10 for the wheel cover 6. Since load is carried by the leaf springs 3 and the coiled spring 4, a buffering property is enhanced. The distance (d) between the axes of the moving wheel  and the steering shaft is increased further by the deflection of the leaf springs 3 and  the vertical tension of the coiled spring 4 acts effectively due to road surface resistance in movement so that a trailing property is heightened. As a result, the trailing  property of a caster is enhanced as a whole and the directivity of the movement is stabilized.
