Title: Production of magnesia whisker
Inventor: NISHIYAMA ATSUSHI
IPC: C30B29/62
Filed: 1988-06-08
Abstract: PURPOSE:To obtain Mg whisker having high performance in high efficiency at a low cost, by dehydrating and calcining a mixture of a halogen compound and an Mg salt having crystallization water under specific condition. CONSTITUTION:An Mg salt having crystallization water (e.g., MgCl2.6H2O) is mixed with a halogen compound (e.g., KCl) at a molar ratio of 0.5-2.0. The obtained mixture is filled in a heat-resistant container, inserted into a tubular atmosphere furnace, heated in stationary state at a heating rate of 2-5 deg.C/min while passing dry air at a speed of 3-7X10<-3>m/sec and maintained at a dehydration temperature zone (200-500 deg.C) of the Mg salt at <=550 deg.C for >=0.2hr to effect the dehydration reaction. The dehydrated product is calcined at >=600 deg.C for 0.5-5hr under the flow of dry air containing 0.001-0.01mol/l of steam to effect the growth of Mg whisker having a fiber length of 30-200mum on the inner wall surface of the reaction vessel. The whisker is washed with water to remove impurities.

Title: Etching monitor
Inventor: HASEGAWA MITSUTOSHI
IPC: H01L21/3065
Filed: 1986-06-19
Abstract: PURPOSE:To control and finish etching automatically by monitoring the change of the etching depth during dry etching. CONSTITUTION:A mask 2 is formed on a substrate 1 surface and dry etching is performed. During the etching, a scanning beam 5 is applied to the mask 2 from a scanning beam source 3 provided above the mask 2 with an incident beam angle theta and a reflected beam 6 which is reflected by the mask is detected by a detector 4. The detected point is denoted by A0. Then, if the scanning beam scans the mask surface to its end, the detected point of the reflected beam reflected by the mask suddenly shows a significant change to the detected point of the reflected beam reflected by the substrate 1 surface. If the point before the sudden change is denoted by A1 and the distance between A1 and A0 is denoted by lo and the point after the change is denoted by A2 and the distance between A2 and A0 is denoted by l1, the etching depth d1 is obtained by the relation d1 = (l1 -l0)sintheta. The value d2 obtained by reducing the mask thickness d0 from the value d1 corresponds to the etched depth so that the change of the etching depth in dry etching process can be monitored.

Abstract: PURPOSE:To measure the characteristics of a function block estimated in a planning stage by mounting a selector selecting either one of an output signal from a functional aspect and the input signal supplied from the outside to output the same. CONSTITUTION:When the change-over signal of a delay time measuring mode supplied from an input pin 3 is set to a low level, the output signals outputted from terminals 2a, 2b become the almost same logic as the output signal outputted at the time of the original operation of a mega-macroscopic cell 1. Therefore, the states of the terminals 2a, 2b at the time of the original opera tion of the cell 1 are outputted to output pins 11a, 11b. When the change-over signal of the delay time measuring mode supplied from the pin 3 is set to a high level, the output signals outputted from the terminals 2a, 2b become the almost same logic as the input signal for measuring a delay time supplied from an input pin 6. Therefore, the input signal for measuring the delay time is outputted to the pins 11a, 11b in the same logic so as to contain a predetermined delay time.

Abstract: PROBLEM TO BE SOLVED: To improve a new visual effect and to improve a fabrication preventive effect due to copying by making to coexist a pattern showing specified information in the pattern. SOLUTION: A cell (e.g. left figure) consisting of the same or near directional diffraction gratings is illuminatedly visualized from its direction since diffracted light is emitted in the similar direction when it is illuminated by the light with small diffusibility, and a specified information pattern (e.g. a right figure (F) character pattern) constituted of a collection of these cells is recognized. However, when it is illuminated by the light with large diffusibility such as a luminescent lamp, etc., since these cells don't emit the diffracted light in the similar direction, the pattern becomes difficult to be recognized. When it is copied by a copying machine, its scanning light is provided regularly with the diffusibility in the one direction, and the pattern appears clearly on a copied matter according to a copying condition, and the copied matter is recognized easily.
