Title: Production of fine high-purity silica powder
Inventor: MATSUMOTO TEIJIRO
IPC: C01B3/12
Filed: 1986-04-12
Abstract: PURPOSE:To efficiently produce fine high-purity silica powder in simple operation, by using a ball mill lined with quartize containing a low concentration of uranium and grinding lumps of high-purity quartzite having cleaned surfaces without using balls. CONSTITUTION:Lumps of raw ores are mutually ground in a ball mill lined with alumina or quartzite to shave off the surfaces without using balls and give lumps of high-purity quartzite having cleaned surfaces. The resultant lumps of the high-purity quartzite (having about <=10cm major axis and <=10ppb uranium content) are then ground in a ball mill lined with quartzite containing a low concentration of uranium (<=100ppb uranium content) without using balls. Thereby the aimed fine high-purity silica powder with a low uranium content useful as a filler for a sealing medium is industrially and advantageously produced.

Patent JP-S63250175-A (JP)
Title: Manufacture of semiconductor device
Inventor: HONMA AKIRA
IPC: H01L29/78
Filed: 1987-04-07
Abstract: PURPOSE:To obtain high controllability and high uniformity in mutual conductance and drain withstand voltage, by forming a gate electrode of polycrystal silicon on a gate insulating film which is disposed on a substrate and next by forming an impurity layer on only a lower region of an impurity diffusion part of a gate electrode. CONSTITUTION:After a silicon oxide film 4 on a gate electrode 3 is removed by an etching method, implantation of phosphorus ions P is performed from above. In this process, since an impurity diffusion part 5 of the gate electrode is much deteriorated in its ability of interrupting implanted ions, proper selection of an acceleration voltage allows the implanted ions to be interrupted at an impurity non-diffusion part 6 of the gate electrode and to pass in some degree through the impurity diffusion part 5 of the gate electrode. Accordingly a low concentration impurity diffusion layer 7 can be formed also inside the semiconductor substrate 1 below the impurity diffusion part 5 of the gate electrode. A length of the low concentration impurity diffusion layer can be controlled with high precision and high uniformity.

Abstract: PURPOSE:To absorb the vibrations produced when the acceleration/deceleration is controlled and to ensure the smooth drive, by giving an weighting operation to the shift amount component for weighted average and setting an acceleration pattern, etc. in a desired from before the speed reaches a designated level. CONSTITUTION:A rough interpolator 1 performs a prescribed operation at an X/Y shaft drive control part of a machine system like a robot, etc. and produces the rough interpolation data of each shaft per sampling action. These rough interpolation data are supplied to the acceleration/deceleration circuits 11 and 21 which consist of the 1st and 2nd arithmetic parts 12, (m) pieces of buffer registers #1-#m, etc. The weight parameters (ai) and (bi) of the circuits 11 and 21 are set by a parameter setting circuit 30. Thus these parameters (ai) and (bi) are set properly and the output obtained by giving the weighted average to a prescribed number of shift amount components is supplied to a pulse distributor as an indicated speed for acceleration/deceleration control of the machine system. This can reduce a sudden change of the acceleration and deceleration.
