摘要： An electric motor comprises a first motor element (6) and a second motor element (1) coaxially disposed on a motor axis and thereby defining an air gap. A first number of magnetic poles (5) is disposed on the first motor element (6) adjacent the air gap and produces a plurality of circumferentially equispaced magnetic fields in the air gap, adjacent fields having opposite polarities. A second number of armature means (2) is disposed circumferentially on the second motor element (1) for generating an equal number of poles, the armature means (2) being divided into groups, in which all the armature means (2) of a group are energised substantially in phase and generate adjacent poles of opposite polarity, wherein the second number does not equal the first number. The second number may be 9 and the first number 8 or 10 or the second number may be 15 and the first number 16 or the second number may be 21 and the first number 20 or 22.

摘要： The present invention relates to an annular sealing member (7) arranged so as to surround the periphery of a working member such as a shaft (10). This sealing member (7), is produced by sticking a sheet (1) of elastic magnet to pole piece-constructing sheets (2, 2) and punching the resulting assembly. The annular portion of said sheet (1) of elastic magnet is pressed to be contracted in the direction of thickness and stretched in the radial direction by said punching. As a result, the circumferential portion of the above described annular magnet (8) is dislocated so as to be sunk from the periphery of said annular pole pieces (9, 9). Accordingly, the dimensional accuracy of inner and outer circumferences of the sealing member (7) is improved.

摘要： A sealing member for sealing magnetic fields according to the present invention is a sealing member (1) arranged so as to surround a periphery of a working member (5) such as shaft. The sealing member (1) comprises an annular magnet (2) and an annular pole piece (3), an electrically conductive magnetic fluid (6) being provided between the sealing member (1) and the working member (5) to construct an electrically conductive magnetic fluid-sealing member. And, an inner circumferential surface of the annular magnet (2) is coated with an electrically conductive non magnetic film (4) continuing to the annular pole piece (3) to down-size the sealing member (1) and reduce an electrical resistance.

摘要： In conventional thermoelectric conversion modules, P-type and N-type thermoelectric semiconductor chips are alternately arranged in both the longitudinal and the transverse directions. Consequently, assembling work is complicated and there arises the problem in quality that erroneous types of chips are arranged. In the present invention, therefore, rows or columns of chips are constituted by thermoelectric semiconductor chips (4, 5) of the same type, to improve the assembling workability as well as to prevent erroneous arrangements. As a preferred fabricating method, bar-shaped thermoelectric semiconductors are used and are joined to one substrate (1) and then are electrically disconnected (8) between leads (2) to form the individual chips.
