Filed: 1989-06-15
Abstract: PURPOSE:To easily adjust inductance with simple structure by providing the inductance to a lead part itself which is connected to an external circuit, also providing mutual inductance produced by magnetic inductance coupling, and thus forming a lead part for inductance adjustment. CONSTITUTION:Lead wires 41-1 and 41-2 are connected and fixed to the open terminal of the internal conductor 36 of a coaxial dielectric resonator 30 with solder 42, etc., and the other terminal is connected and fixed to a pattern 22 on a substrate 21 similarly. The interval between those two lead wires is increased or decreased to decrease or increase the mutual inductance M, namely, the composite inductance. Therefore, while the inductance of the resonator 30 is held fixed, the inductance of the whole can be adjusted by adjusting the interval of the lead part 40. Namely, when this method is used in the resonance circuit of an oscillator, the oscillation frequency can be adjusted. Consequently, the adjusting operation is facilitated with the extremely simple structure, and the versatility of the dielectric resonance system can be improved.

Title: Apparatus for producing semiconductor single crystal
Inventor: MAITA YASUSHI
IPC: C30B27/02
Filed: 1986-06-27
Abstract: PURPOSE:To produce a semiconductor single crystal having excellent electrical uniformity, by placing a magnetic field generator at and near the coagulation proceeding part where a molten semiconductor raw material is being converted to a crystal. CONSTITUTION:A semiconductor crystal 58 is pulled up and grown from a coagulation proceeding part 60 of a molten liquid 51 by lifting a rotary shaft 55 at a low speed under rotation. In the above crystal production period, an electromagnet 62 is electrified to generate a magnetic field at and near the coagulation proceeding part 60. The magnetic field inhibits the generation of local convection in the molten liquid 51 in the magnetic field, i.e. at and near the coagulation proceeding part 60 by the density difference caused by the nonuniformity of temperature distribution in the molten liquid 51. If a convection occurs, it is suppressed to an extremely low level. Accordingly, the nonuniformity or fluctuation of the liquid temperature at or near the coagulation proceeding part 60 can be suppressed and a semiconductor crystal 58 having excellent electrical uniformity and free from stripe texture can be produced.

Abstract: PURPOSE:To make it possible to obtain a flow speed meter with high accuracy, by using a polarization surface preserving optical fiber connected to a Faraday element at one end thereof and to a fluid to be measured at the other end thereof. CONSTITUTION:Light from a light source 1 is subjected to linear polarization through a polarization plate 2 to be connected to the optical axis of a polarization surface preserving optical fiber 4' by a lambda/2 plate 3. Linearly polarized light emitted from the fiber 4' is permeated as the P-wave of a polarization beam splitter 5 and further inclined 45 deg. by a Faraday element 6 to be connected to the optical axis of a polarization surface preserving optical fuber 4. There are two kinds in light returing from the leading end of the fiber 4 against light propagating to the leading end thereof and the first one is light reflected at the leading end of the fiber 4 while the second one is light scattered by a fluid 8 in the vicinity of the leading end of said fiber 4 and generates a frequency shift amount wherein a wavelength is proportional to a flow speed. These reflected lights are further rotated 45 deg. by the element 6 and reflected by the splitter as a S- wave to be received by a light receiver 7. By calculating the frequency shift amount in this receiver 7, the flow speed of the fluid is calculated.
