Title: Manufacture of insulating layer
Inventor: AMAMIYA YOSHIHITO
IPC: H01L21/314
Filed: 1983-02-26
Abstract: PURPOSE:To enable to reduce the cubical expansion of an insulating layer when a processing is performed thereon by a method wherein an element, which will be changed into a volatile substance while an oxidizing or nitriding process is being performed, is mixed into a silicon layer. CONSTITUTION:When an insulating layer is going to be formed, a silicon layer containing an element which volatilizes and evaporates when it is oxidized or nitrided is deposited, then said silicon layer is oxidized or nitrided, and the expansion generating when oxidized is reduced on the whole by cancelling each other of the cubical reduction due to the volatilization and vaporization of the element contained. Germanium is considered to be suitable for the above-mentioned element, a solid solution is formed using the germanium and the silicon in an arbitrary rate, the oxide made out from the above shows a volatile property at a high temperature, and the nitride shows a stronger volatile property. For example, a solid solution microscopic crystal layer of silicon and germanium is deposited on an oxide film 12, and an oxide film 13 is obtained by oxidizing the above solid solution microscopic crystal layer. Germanium is not left in said oxide film 13, and the irregularity in the resistance value of the layer is small.

Title: Shuttle conveyor system with lifting chute
Inventor: MIZUTAME KAZUYA
IPC: B65G69/18
Filed: 1986-02-18
Abstract: PURPOSE:To reduce operating time of a chute to the shortest possible extend as well as to aim at prevention of dust from occurring, by making a lifting chute driving motor variable in speed, and controlling it to meet an optimum chute up speed with each signal out of a lower limit level detector of the lifting chute, a topmost position detector and a base level detector. CONSTITUTION:A shuttle conveyor 1 is rotated whereby a conveyed load 12 drops on the ground by a lifting chute 5 and it is stacked up. This stacking-up part 10 is detected by a lower limit level detector 7, and an up speed signal of the lifting chute 5 is outputted according to the stacking state. And, unless a topmost position of the lifting chute 5 is anot judged as well as unless a fact that a specified quantity of the conveyed load is stacked up is not judged, this stacking-up operation is continued at the up speed corresponding to the signal out of the lower limit level detector 7. If the specified quantity of the conveyed load is judged as already dropped, the next stacking-up form is judged by a base level detector 9 at the next stage, and if the next stage is higher than the lifting chute position, a high-speed up command is emitted. And, when it is moved to the next position, the lifting chute is made to go down up to a lowermost position. Accordingly, movements for up and down can be done in a short time and, what is more, the occurrence of dust is reducible.
