Title: Electromagnetic power supply device
Inventor: TAKEUCHI KAZUYOSHI
IPC: H01F38/14
Filed: 1992-11-19
Abstract: PURPOSE:To obtain an electromagnetic power supply device wherein damage prevention of abutting end surfaces and gap loss reduction are possible. CONSTITUTION:A primary core is made to abut against a secondary core, and a magnetic circuit having a gap is formed. AC power is transmitted from a primary coil to a secondary coil. Magnetic material parts 6, 7 stuck to at least one abutting end surface of both cores absorb or disperse the shock at the time of core abutting, and increase the strength of the core abutting end surfaces. Thereby generation of fracture and crack of the abutting end surfaces of ferrite cores at the time of core abutting are prevented. Since the magnetic material parts 6, 7 have high permeability, gap loss is reduced. Slits formed in the magnetic material parts 6, 7 decrease the eddy current of the magnetic material parts 6, 7.

The sample 1 thrown into the cyclone 3 is separated into powder having particle size of 1μm or less and 1μm or above by a swirling gas flow generated by argon gas. Powder having particle size of 1μm or less is introduced, along with argon gas, from the outlet 8 of cyclone 3 to a plasma torch 2. The sample 1 thus introduced emits light in the plasma torch 2 and the components of sampled from the spectrum of emitted light.

Filed: 1988-12-09
Abstract: PURPOSE:To completely magnetize even a magnet material of a low magnetization property by a method wherein a uniform magnetic field is applied in a radius direction of the magnet material of a hollow cylindrical shape and an electric current is applied to a plurality of pair conductors arranged in an axial direction on an outer peripheral face of a center yoke one after another according to a prescribed combination. CONSTITUTION:A magnet material 24 is housed between a center yoke 21 and an outer-periphery yoke 23; an electric current is applied to a coil 25; a magnetic flux is generated along a magnetic route M4; it is possible to uniformly magnetize the material 24 in a radius direction. However, the yoke 21 is saturated magnetically in this state; accordingly, when the material 24 is formed of a rare-earth material of a low magnetization property, it cannot be magnetized completely. Accordingly, the electric current is applied to a plurality of pair conductors 22 arranged and installed in an axial direction at an outer periphery of the yoke 21 in a state that the electric current has been applied to the coil 25; then, a partially large magnetic field can be formed. Thereby, when a connection of the conductors 22 is changed and a direction of a magnetic field is changed one after another, the magnet material can be magnetized completely.

Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a means which constitutes a three-dimensional distance (depth map) measuring instrument having a superhigh quality by eliminating virtual images and occlusion which are the essential point at issue of the conventional three-dimensional distance (depth map) measuring instrument. SOLUTION: In an example of a simple constitution based on a fundamental idea, at least one A of a plurality of picture taking equipments A and B constituting a three-dimensional distance (depth map) measuring instrument is instantaneously rotated (the center of rotation is different from the position of a base point) or moved by using the position where the equipment A is set up as the base point. As the equipment A is rotated or moved, the movement of all virtual images produced in measured results can be observed, but the movement of a real image is not observed. In addition, the area where occlusion occurs is increased or decreased as the equipment A is rotated or moved. Therefore, all virtual images and occlusion can be found by using the observed results.

Title: Threshing device
Inventor: USUI KATSUYA
IPC: A01F12/32
Filed: 1990-11-16
Abstract: PURPOSE:To maintain stabilized sieving motion performance by controlling chaff sieve so as to operate on open side when the detection amount of a sieve sensor becomes upper limit or above in prescribed range and so as to operate on closed side when the detection amount becomes lower limit or below. CONSTITUTION:A control device adapts average value of time longer than oscillating cycle of an oscillating and sorting plate 3 and the average value is obtained as detection value corresponding to thickness of layer of a treated material. When thickness of layer of the treated material becomes upper limit or above in preliminarily set range (insensitive band), chaff sieve 8 is operated on open side to increase the leak amount of the treated material. On the contrary, when thickness of layer of the treated material becomes lower limit or below of insensitive band, chaff sieve 8 is operated on the closed side to decrease the leak amount of the treated material. Thereby thickness of layer of the treated material can be kept nearly constant and stabilized sieve action performance can be maintained.
