Patent JP-H0496681-A (JP)
Title: Vector controller for induction motor
Inventor: YAMAMOTO YASUHIRO
IPC: H02P27/08
Filed: 1990-08-13
Abstract: PURPOSE:To compensate inner constants for temperature fluctuation without requiring a high accuracy sensor by compensating the set value of secondary resister with the difference between a detected value of average speed and an estimated speed of a motor as a temperature fluctuation of the secondary resistance. CONSTITUTION:A speed detecting circuit 12 takes out an average angular frequency omegara of a motor 2 and a correction amplifier 15 takes out the difference between the average angular frequency omegara and an estimated rotor angular frequency omegar of the motor under steady state. The detected speed omegara is an actual speed of the motor 2 and the difference, if any, between the detected speed omegara and the estimated speed omegar means some cause of error. If a primary resistor R1 has a true value, error of secondary time constant tau2, i.e., temperature fluctuation of secondary resistor R2 (fluctuation of secondary inductance is quite low), may be accounted for. Consequently, steady speeds omegara and omegar are fed to the correction amplifier 15 which corrects the slip angular frequency omegas so that the difference between the speeds omegara and omegar will be zero thus performing temperature compensation of the secondary resistor R2.

Title: Apparatus for manufacturing polycrystalline silicon
Inventor: OBATA MASAAKI
IPC: C01B33/02
Filed: 1982-12-07
Abstract: PURPOSE:To deposit efficiently polycrystalline Si on the surface of seed Si by feeding gaseous H2 as a reducing agent to a fluidized bed reactor from the porous inner wall when an inorg. silane compound and gaseous H2 are fed to the reactor to deposit polycrystalline Si on the surface of seed Si. CONSTITUTION:An inorg. silane compound such as silicon tetrachloride, trichlorosilane, dischlorosilane, monochlorosilane or monosilane is fed to a fluidized bed reactor 1 from an inlet 6 for introducing a gaseous starting material. Gaseous H2 as a reducing agent is fed to the space between the outer wall 9 of the reactor 1 and the porous inner wall 10 from inlets 8 for introducing H2, and it is spouted from many pores in the wall 10 and reacted with the silane compound. The silane compound is reduced and deposited as polycrystalline Si of high purity on the surface of polycrystalline seed Si charged into the reactor 1 from a charging inlet 3. Since the reaction is an endothermic reaction, polycrystalline Si is liable to deposit on the inner wall 10 adjacent to a heater 2. Gaseous H2 spouted from the pores in the wall 10 prevents deposition on the wall 10, so polycryltalline Si is deposited on the surface of seed Si in a high yield.

Abstract: PURPOSE:To make the growth speed of a crystal film uniform on the whole area of a substrate by positioning the tip of a carrier gas supply tube inserted concentrically in a reaction gas supply tube, the tip being projected closer to a susceptor than the tip of the reaction gas supply tube, near the surface of the substrate on the susceptor. CONSTITUTION:A carrier gas supply tube 5 which introduces an inert gas for the reaction of crystal film growth into a reaction tube 1 and has a smaller external diameter than the internal diameter of a reaction gas supply tube 3 is concentrically inserted in the tube 3 and the tip of the tube 5 is projected from the tip of the reaction gas supply tube 3 toward a susceptor 2 and positioned near the surface of a substrate 4 installed on the susceptor 2. Accordingly, the concentration of the reaction gas within a boundary layer is reduced, the crystal film growth speed near the axis of the reaction tube where dilution effect is high is reduced and the difference of the growth speed due to the difference of the thickness of the reaction gas flow boundary layer is corrected by the difference of the concentration of the reaction gas due to dilution. This enables growing a uniformly thick crystal film on all the surface of the substrate.

IPC: F16F13/00
Filed: 1992-08-13
Abstract: PURPOSE: To reduce the cost of production and construction of a rubber bearing by forming a flexible wall section and a diaphragm integrally molded into a one piece, and fastening the molding to a partition wall fluid-tight at the middle zone between the wall section and the diaphragm. CONSTITUTION: A liquid-filled activating chamber 4 is separated from a compensation chamber 6 by the partition wall 5. The partition wall 5 is fastened to a supporting mount 1 and has a port 7 to communicate the activating chamber 4 with the compensation chamber 6. A section of the partition wall 5 is formed by a flexible wall 8 to cause decoupling of high- and low-frequency vibrations. The diaphragm 8 sealing the compensation chamber 6 from outside is secured to the supporting mount 1, and the flexible wall 8 and the diaphragm 9 are constructed to integrally and mutually move to form a molding 10. A tightening ring 15 tightly presses the molding 10 to the partition wall 5, and prevents direct fluid exchange between the activating chamber 4 and the compensation chamber 9. Thus, production and construction of the rubber bearing are facilitated with less components.
