IPC: H02P6/08
Filed: 1990-06-08
Abstract: PURPOSE:To reduce power consumption by detecting the relative position of the position of the magnetic pole of a rotor and a three-phase winding by a conductive pattern, from which a measured voltage value is obtained. CONSTITUTION:Conduction at 180 deg. to star-connected three-phase windings U, V, W is made conductive successively by each of six kinds of conductive patterns. Consequently, the relative positional relationship of the positions of magnetic poles formed by magnetization to a rotor 30 under the state of stoppage and the locations of three-phase windings U, V, W can be determined according to the states of six neutral-point voltage values at the transient time measured discretely at a neutral point Pcom in response to conduction by six kinds of the conductive patterns. That is, a control signal is transmitted over a commutation control circuit 4 from a controller 1, and the commutation control circuit 4 is operated so that conduction at 180 deg. to the three-phase windings U, V, W is performed successively to each of six kinds of the conductive patterns at every predetermined short time set to a timer 3.

Abstract: PURPOSE:To investigate the state in a tube quantitatively and qualitatively by installing a sound wave transmitter at one terminal of the tube and a sound wave receiver at the other, and measuring a transmitted sound wave. CONSTITUTION:A sound wave signal which is frequency swept within a range of about 50Hz-20kHz is generated by a signal generating circuit 1 and irradiated into the tube 6 from a cone speaker 3 installed at one terminal of the tube 6 whose ends are both open, and its transtmitted wave is received by an electret microphone 4 installed at the other terminal and stored in a waveform storage device 2. The transmitted wave stored in the storage device 2 is indicated on an indication meter to know the interval of the resonance frequency of the transmitted wave and the distance L from the speaker 3 to a position A where the in-tube hollow sectional area varies. Further, the length W of the position A is known from the cutoff frequency and in-tube speed of the transmitted wave. Furthermore, the sound pressure of the transmitted wave of a tube of the same diameter and length with the tube to be investigated is measured previously and the difference in the sound pressure from the investigated tube is calculated to know the in-tube hollow sectional area at the position A.

Abstract: PURPOSE: To form a device of high quality which operates stably on an insulation substrate without forming a parasitic MOS on the flank.  
     CONSTITUTION: On sapphire substrate 31, an island of Si thin film 32 is made,  thermally-oxidized coating 34 is formed, and CVDSiO 2 34' is stacked. Sensitive agent 35 is applied and only the part over layer 32 is selectively removed. Films 34 and 34' are removed by mask 35, which is also removed, so that Si 32 will be separated in an island shape with SiO 2  films 34 and 34' between. In this method, oxidized film 34 can be formed much faster than a conventional one, impurity contamination from the insulation substrate to layer 32 is reduced, and an increase in crystal defect can be prevented which is caused by differences in thermal expansivity and lattice constant. In addition, since the flank is covered with a thermally-oxidized film, the interface is hard to get contaminated and at the time of formation of a MOSFET, the leakage caused by the parasitic MOS generated on the flank is reduced, so that the device will become stable.
