IPC: C30B25/00
Filed: 1989-03-31
Abstract: PURPOSE:To enlarge the grain diameter by reacting a gaseous raw material substance with a gaseous halogen-based oxidizing agent in a film-forming space and forming a crystal film on a specific substrate. CONSTITUTION:A glass substrate 3 is installed on a substrate holder 5 and the surface temperature of the substrate is kept at about 450 deg.C by combination of heating with an infrared heater 7 and cooling with water at a constant temperature. Low-temperature regions having about 2mum diameter at about 50 deg.C are prepared at a prescribed interval using a mask filter 10 and the interior of a film-forming chamber 1 is evacuated to about <=5X10<-8>Torr. A halogen- based oxidizing agent, such as F2 gas, diluted to about 10% concentration with He is then introduced from gas introduction pipes 15 and a gaseous raw material substance, such as SiH4, is introduced from gas introduction pipes 14 to form a film under about 0.2Torr pressure in the chamber 1 for 2min. The substrate is subsequently heated to about 400 deg.C and the mask filter 10 is removed to homogeneously heat the substrate surface for about 1hr and carry out deposition. The introduction of the gases is then stopped to stop the heating and cool the substrate 3. The substrate is then taken out to afford a polycrystal Si film in which grain diameter is grown to about 2.5mum at a prescribed interval.

Abstract: PURPOSE:To measure a flow rate when the flow velocity is high and the concentration of suspended sand is high by making the partition wall of two sand collection boxes higher than the periphery and fitting two suspended sand inflow preventive plates which have tip parts bent mutually outward rotatably to the partition wall. CONSTITUTION:When the sand collection boxes 3 and 4 are installed on the bottom of the sea, the top end of the partition wall 15 projects from the bottom surface 22 of the sea. If there is a leftward surge flow velocity, the suspended sand inflow preventive rotary plates 17 and 18 fitted to the top end rotate counterclockwise to open the box 3, but close the box 4. Therefore, drift sand flows in the box 3 as shown by 11 in a nearly half cycle period wherein the peak of a wave passes on the box 3 and part of it is deposited nearby the shaft 19 of the rotary plate 17. Further, suspended sand 14 which is to settle in the box 3 is sucked up and diffused nearby the surface of the rotary plate 17 because the pressure is small and the flow velocity is fast. In a next cycle period, the surge flow becomes rightward and the rotary plates 17 and 18 rotate clockwise; and the sand 10 deposited nearby the shaft 19 at this time flows in the box 3, which is closed. here, the drift sand 10 which should be collected in the box 3 is all collected. The box 4 is the same.
