Patent JP-H09322579-A (JP)
Title: Speed control signal generation circuit of motor
Inventor: UNO JUICHI
IPC: H02P29/00
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To generate acceleration and deceleration commands with a single counter. SOLUTION: Pulses for one period of FG pulses (input signals) are outputted by first and second edge detection circuits 40 and 42. A counter 44 is reset by the output of the second edge detection circuit 42 and then a clock CLK is counted. Then, when a certain time passes and the clock is counted up, a count-up signal is outputted from a count-up detection circuit 50 and hence a flip-flop 54 is set to '1' until the next output of the second edge detection circuit 42 and a slow signal (acceleration signal) S is outputted during that period. On the other hand, when an edge is detected before count-up, the difference between the count value and the count-up value at that time is retained in a data retention circuit 48 by the first edge detection circuit 40.  Then, a fast signal (deceleration command) F is outputted until the count value of the counter 44 matches this value by a coincidence detection circuit 64.

IPC: H01L21/265
Filed: 1977-11-09
Abstract: PURPOSE: To control impurity concentration of diffused layer by implanting impurity ions through ion implantation into the insulation film of a semiconductor substrate and performing diffusion in the semiconductor with this insulation film as a diffusion source.  
     CONSTITUTION: Silicon dioxide 2 is grown on monocrystalline silicon 1 and a pattern for obtaining diffused layers is formed through photo resist 3. Next, boron B +  ions 4 are doped into the silicon dixode 2 through ion implantaion to convert the silicon dixode to borosilicate glass 5. Next, the photo resist 3 is removed, after which drive-in is performed in an inert gas atmosphere, whereby a P type diffused layer 6 is obtaind. As a result, the P type diffused layer 6 having been formed has less variations in impurity concentration owing to the controlled doping through ion implantation and since the silicon dioxide is thick, the out-diffusion of the impurity from the inside of the silicon substrate is less.
