Inventor: ICHIKAWA HIDEKI
IPC: H02K3/18
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To miniaturize the radial constitution of a stator using straight angle conductors and make their winding works easy. SOLUTION: A stator 1 has both a cylindrical yoke 3 with four field poles 2 and four straight angle conductors 4 wound respectively along the peripherals of the four field poles 2. One end portion of each straight angle conductor 4 deforming each field coil 7 is connected with each field pole 2. Also, the adjacent field coils 7 to each other are wound in the opposite directions to to generated the field poles 7 to the opposite polarities and the other end portion 4b of each straight angle conductor 4 is drawn out in the vicinity of the other end portion 4b of the adjacent straight angle conductor 4 to be connected with the other adjacent end portion 4b. Still, the cylindrical yoke 3 is formed by coupling four yokes 5 divided every field pole 2 to each other, and prior to coupling each divided yoke 5 is rotated to wind each straight angle conductor 4 around each field pole 2.  Therefore, each straight angle conductor 4 is wound around each field pole 2 easily and with a high space factor. Also, the one end portion of each straight angle conductor 4 is not drawn out to the external and not subjected to a twist of 90 deg., thereby making the diameter of the stator 1 reducible.

Title: Multilayer film spectral reflection mirror
Inventor: TAKENAKA HISATAKA
IPC: G21K1/06
Filed: 1992-03-09
Abstract: PURPOSE:To improve heat resistivity compared with multiple layer film using Si by using Si compound for the light element layer in multilayer spectral element having Bragg diffraction effect. CONSTITUTION:Though the melting point of Si is about 1410 deg.C, it is elevated by making an Si compound. For example, the melting point of SiO2 is about 1550 deg.C, Ti5Si3 is about 2120 deg.C, HfSi is about 2600 deg.C. Therefore, a material having a higher melting point than Si is used for heavy element layer and in the multielelement layer using an Si compound for the light element layer, the heat resistivity of the multilayer film improved. When the multilayer film like this is applied to various analysis using X-ray and soft X-ray, the reflectivity change decreases because of improvement in resistivity of multilayer film and accuracy and probability improve. Also, when it is applied to an X-ray lithograph, the reflectivity change decreases because of the similar reason and proper exposure time is accurately determined.

Abstract: PURPOSE:To prevent the failure of the searchfier device and the generation of dust by commanding a mode change with the signal from an impact force detecting circuit to which an impact force signal detected by a writing/reading out head is inputted. CONSTITUTION:This device makes measurement of the electromagnetic conversion characteristics of the magnetic film of a magnetic disk medium 5 and detection of defect points, such as ruggedness and impurity intrusion, of the magnetic film layer via the writing/reading out head 2. An impact force detecting element 1 is mounted on the head 2 at this time to measure the impact force from the medium 5. This signal is detected by the impact force detecting circuit 11 which delivers a stop signal to a control circuit 4 of a carriage motor 3 for moving the head 2 and a control circuit 7 of a spindle motor 6 for rotating the medium 5 and delivers an alarm signal to a control section 9 which controls the respective circuits for the purpose of various kinds of the measurement. The control section 9 sends the stop signal to interrupt various kinds of the measurement and monitors the stop of the motors 3, 6 by this signal. The measurement is, therefore, interrupted in the initial period of the accident to the failure of the magnetic film of the medium 5 and the head 2.

Title: Method for division of trapezoid for variable formation electron-beam exposure
Inventor: NAKAO HIROOMI
IPC: G03F7/20
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent an extremely small trapezoid from being formed and to reduce the number of divided trapezoids as far as possible by a method wherein the influence on a manufacturing accuracy of dividing lines drawn in the horizontal direction and the vertical direction from respective vertexes of a graphic is evaluated and an optimum dividing pattern is selected on the basis of its evaluation value. SOLUTION: Regarding dividing lines in the horizontal direction and the vertical direction from all vertexes of a graphic, their costs and their cost reduction are computed (ST 2). Then, by using the computed costs and the computed cost reduction of the respective dividing lines, a desirable dividing pattern (dividing lines) is selected (ST 3), and the graphic is divided by using the selected dividing lines (ST 4). When the graphic is not divided completely into trapezoicls, a dividing treatment is repeated (ST 5). At this time, when the relationship of the intersection and the contact between the dividing lines is memorized, a dividing operation is performed with good efficiency. In addition, it is possible to restrain a trapezoicl in an extremely small graphic width from being generated.  When priority is given to the suppression of the division of a critical part over a reduction in the number of divided trapezoids, a treatment which takes this into consideration is separated.

Title: Balanced-unbalanced type transformer
Inventor: SATOU NORIO
IPC: H01F27/42
Filed: 1982-03-30
Abstract: PURPOSE:To improve efficiency of coil winding through rough coupling between both windings making unnecesary insertion of insulating layer by employing the wiring structure that both wirings of balanced and unbalanced wirings are arranged closely at the low voltage areas. CONSTITUTION:If balanced wirings 11, 12 are perfectly balanced, the connecting part of the wiring start point 11b and end point 12a becomes the neutral point of the balanced winding and is set to zero voltage. When the terminal in the unbalanced side is earthed, the start point 13a and end point 14b are set to zero voltage. Therefore, when the winding structure shown in the figure is employed, the low voltage areas of both balanced and unbalanced windings are arranged closely, while the high voltage areas of them are isolated. Meanwhile, capacitance between windings is much distributed at the area where the unbalanced winding is closely located to the balanced winding. But it is less distributed at the area being apart from such area and accordingly coupling between balanced and unbalanced windings through capacitance is as much reduced. Therefore, it is no longer necessary to provide an insulating layer at the interim of balanced and unbalanced windings.
