IPC: G01S19/28
Filed: 1991-11-19
Abstract: PURPOSE:To catch and track a satellite suitable for the position survey in a short time when transformation of a coordinate system is ordered, by setting a satellite selecting means which predicts the course of the satellite to select the satellite suitable for the position survey. CONSTITUTION:When a survey position is moved to an area where a coordinate system which is different from the former one should be used, an user inputs 6 the name or the number of the new coordinate system into an arithmetic unit 2 for making a coordinate system modification means 2d output the name or the number of the new coordinate system to a coordinate transformation means 2b and output the specific longitude and latitude of the area where the new coordinate system should be used to a memory means 3 to modify the output result of the former position survey. Under these conditions, a satellite selecting means 2c selects a satellite suitable for the position survey before the start of the position survey and sends information to a satellite signal receiving part 1. In this constitution, if a survey position is moved to a long distance from the former position, or the power supply is cut off when a survey position is moved to a long distance from the former position, a waste of processing time for an unsuitable satellite can be eliminated and a suitable satellite can be acquired and tracked instantaneously.

Abstract: PURPOSE:To fully utilize motor capacity and increase an output by changing the rotational speed of a motor, where field-weakening control begins to display an effect, to the high speed side to the reduction of the travelling load of a car. CONSTITUTION:The revolution of a rotor is converted into a binary signal by an interface 52 through a rotary encoder 50, and changed into the angle of rotation theta on the basis of a translation table stored in a ROM 54. The binary signal is converted into voltage V proportional to rotational speed by an F/V converter 56. Two phase currents iu, iw in the three-phase armature windings of a motor 12 are inputted to a three-phase two-phase converter 60 through an A/D converter 58. The three-phase two-phase converter 60 feeds back flux currents id and torque currents iq to a current amplifier 62. The current amplifier 62 obtains a d-axis voltage command Vd* and a q-axis voltage command Vq* on the basis of a torque command iq* and field current command id*. Field-weakening control characteristics biassing rotational speed, where the field current command id* begins to output in response to the reduction of load, to the high speed side are stored in a field-command generating circuit 74.

Title: Structure for prevention of magnetic flux leakage of electromagnetic device
Inventor: YOSHIMURA FUMIO
IPC: H05K9/00
Filed: 1987-11-30
Abstract: PURPOSE:To enable the effective suppression of leakage of magnetic flux, by enclosing a magnetic flux leakage portion formed on the surface of a magnetic core with a magnetic reluctance layer of a small relative permeability and forming a magnetic path layer of a large relative permeability along the surface of the magnetic reluctance layer. CONSTITUTION:A coil 1 and a magnetic core 2 are fixed by caulking inside a casing 3 made of a steel plate formed in a channel by pressing. A pair of block body halves 21 and 21 constituting the magnetic core 2 are formed by piling up many generally E-shaped iron plates. Side plates 4 and 4 of the casing 3 have curved portions 5 extending along the direction in which the iron plates of the block body halves 21 are piled up to form magnetic paths A. Gaps between the curved portions 5 and the magnetic core 2 form magnetic reluctance layers 6 of 0.1-2.0mm thickness T. Magnetic flux generated around the coil 1 would form a magnetic path which avoids a virtual gap G' of a large magnetic reluctance, but the virtual gap G' is enclosed by the magnetic reluctance layers 6. Therefore, a magnetic path passing through the virtual gap G' is formed, decreasing the length of the path.
