Abstract: PURPOSE:To enable the accurate and easy control of the concentration of impurities in an epitaxial growth layer, by mixing a dopant beforehand in the back of a silicon substrate, and by mixing an impurity into the epitaxial growth layer by using said dopant. CONSTITUTION:A silicon source gas formed of silicon tetrachloride and a carrier gas formed of hydrogen, for instance, are sent into a reaction tube 1 as shown by an arrow 7. A single-crystal silicon substrate prepared by introducing a prescribed quantity of phosphine as an n type impurity source, for instance, into the back 9 of the epitaxial growth surface thereof beforehand by diffusion or ion implantation is used as a substrate 8 to be set on a supporting bed 4. The reaction tube 1 is heated by a high-frequency work coil 3 and thereby the silicon source gas of silicon tetrachloride forms an epitaxial growth layer on the surface of the silicon substrate 8 in reaction to this substrate. On the occasion, phosphorus atoms fly out into a vapor phase in the reaction tube 1 from the phosphine introduced in the back 9 of the substrate 8, and mingle as impurities in the epitaxial growth layer.

IPC: A47L13/38
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To suck dust in every position while letting it fall by connecting the part near the other end of a cylindrical part to a sucking inlet to suck air into the suction inlet and rotate a vaned wheel and rotate the duster in the interlocking motion with the rotation of the wheel. SOLUTION: When a frame 1 is inserted in the suction pipe of a vacuum cleaner and it is elecrified through an electric source, a small gear 6 is rotated together with a vaned wheel 4 by the suction force of the vacuum cleaner. An air stream is generated in the periphery of the frame 1 by the suction force of the vacuum cleaner, and thereby, the cleaner begins to suck the peripheral dust. As the frame 1 has a trumpet-shaped form, it can suck a wide range of dust. Meanwhile, the rotary duster body 11 is made lightweight and dust dropped by the duster body 11 is sucked to the cleaner through the frame 1. Hence, it does not raise dust and users hardly suck dust. Therefore it is favorable from the points of view of health and hygiene. As it is unnecessary to swing the duster 11, it is optimum for the aged persons due to easy cleaning.

Abstract: PURPOSE:To rotate a motor resistlessly in a breaking state of an AC power supply by providing an AC input monitor circuit, a braking switch which is closed when sensing a break of the power supply and when being applied an emergency stop signal, and a braking switch drive circuit driving the braking switch. CONSTITUTION:At the same time as an AC input power supply is cut, an AC input monitor circuit 13 senses that and its output is turned off. A base drive circuit 9 turns off the bases of a power transistor module 4 by this signal. Also, a braking switch device circuit 15 closes braking switches 16a, 16b. The rotational speed of a motor decreases and the motor stops for currents flow between windings and braking resistors 12a, 12b, 12c. On the other hand, the smoothed power supply voltage for the braking circuits is kept constant during a time determined by a smoothing capacitor 7 for the control power supply and the consumption current of a control circuit 14. Thereafter, it begins to decrease and becomes zero volt. Thereby, the braking switches 16a, 16b are opened too and the braking switch device circuit 15 becomes OFF-state. Therefore, the windings of the motor become open-state and the motor can be rotated with a weak force.
