摘要： PURPOSE:To cool a bottom bearing through natural ventilation, by forming a downward protruding part to a bottom wall for the bottom bearing to be protruded from an external face of the bottom wall of an enclosed vessel and arranging said bottom bearing in said downward protruding part. CONSTITUTION:Thickness of a supporting member 8A fitted to a hollowed part 6 in a bottom wall 1b of an enclosed vessel 1 is formed larger than depth of the hollowed part 6, accordingly a bottom end part of this supporting member 8A is protruded considerably downward from a bottom face of the wall 1b. Also a bottom level 15 in a hollowed part 9A of the supporting member 8A is placed in a position pretty downward from the bottom face of the wall 1b, accordingly a bearing member 10 fixedly placed on the bottom level 15 in the hollowed part 9A of said supporting member 8A is also in a position protruded from the bottom face of the wall 1b. Generated heat of the bottom bearing 10 is cooled by the method such that the good heat conductive supporting member 8A is cooled by air circulatively flowing in through ventilating holes 17, and reliability of the bottom bearing 10 and its life can be improved.
摘要翻译：目的：通过自然通风来冷却底部轴承，通过向底壁形成向下突出的部分，使底部轴承从封闭容器的底壁的外表面突出，并将所述底部轴承布置在所述向下突出部分中。构成：在封闭容器1的底壁1b上安装在中空部6上的支撑部件8A的厚度形成为比中空部6的深度大，因此，该支撑部件8A的下端部从壁1b的底面。此外，支撑构件8A的中空部9A中的底部水平面15位于从壁1b的底面相当向下的位置，因此轴承构件10固定地设置在所述底部的中空部9A中的底部水平面15上支撑构件8A也处于从壁1b的底面突出的位置。通过这样的方法冷却底部轴承10的发热，使得良好的导热支撑构件8A通过通过通气孔17循环地流动的空气来冷却，并且可以提高底部轴承10的可靠性及其寿命。

摘要： PURPOSE:To increase a radially restoring force by providing both permanent magnets and a disc which is made of magnetic material under the lower face of a bearing seat and at a position where a fixed member is opposed thereto. CONSTITUTION:A bearing seat disc 9 which is made of magnetic material and a casing disc 10 are firmly fit to the lower face of a bearing seats 3 and to a part where a casing 5 is opposed thereto. A plurality of ring-like projections 9a and 10a are integrally formed on the lower face of the bearing seat disc 9 and the upper face of the casing disc 10 around the center of permanent magnets 4 and 6, respectively. In this construction, magnetic flux psi from the permanent magnets 4 and 6 then flows as shown by the two-dotted line. Since magnetic resistance is reduced between the mutually opposed ring-like projections 9a and 10, the density of the magnetic flux psi becomes high so that the electromagnetic fringe effect may be evidently exhibited. The fringe effect aids the encouragement to the radial recovering force.
摘要翻译：目的：通过在轴承座的下表面和与固定构件相对的位置处设置永磁体和由磁性材料制成的圆盘来增加径向恢复力。构成：由磁性材料制成的轴承座盘9和套筒10与轴承座3的下表面和壳体5相对的部分牢固地配合。多个环状突起9a和10a分别一体地形成在轴承座盘9的下表面和壳体盘10的上表面周围的永磁体4和6的中心。在这种结构中，永久磁铁4和6的磁通量psi如双虚线所示那样流动。由于在相互相对的环状突起9a和10之间的磁阻减小，所以磁通psi的密度变高，从而可以明显地看到电磁条纹效应。边缘效应有助于径向恢复力的鼓励。

摘要： PURPOSE:To make high pressureproof nonstandard components unnecessary by connecting one of AC power input parts between rectifying elements of a converter circuit to convert AC power input DC voltage and by smoothing said DC voltage through a smoothing capacitor to convert said voltage into AC voltage through an inverter circuit. CONSTITUTION:As diodes 1 are connected in series in the same direction, a current can be rectified. A DC voltage obtained in this manner is smoothed by a smoothing circuit B so that a DC voltage with a ripple component of less than several % is obtained. When an input voltage is positive, a switching circuit 6 is turned ON to control the positive half cycle of output voltage. When the input voltage is negative, said switching circuit 6 is turned ON to control the negative half cycle of said output voltage. Said DC voltage is converted into an AC power with specified voltage and frequency by an inverter circuit C.

摘要： PURPOSE:To improve the efficiency and the assembling performance by employing an induction motor in a generator motor section thereby enabling high speed rotation of a flywheel. CONSTITUTION:When power is fed from the outside to a coil 59 of a stator core 58, magnetic induction is produced between the stator core 58 and a rotor core 62 and thereby a rotary body 65 rotates around a pivot shaft 56 at a high speed. A flywheel 64 rotating at a high speed stores electrical energy in the form of kinetic energy, which is converted into electrical energy as required and fed as power to a load. During idling operation, iron loss in the stator core 58 can be suppressed by lowering the input terminal voltage.

摘要： PURPOSE:To reduce the number of the components and to simplify the circuit constitution by connecting one of a pair of AC power input parts to the intermediate part of two series-connected rectifier cells of a converter circuit. CONSTITUTION:A variable voltage/variable frequency electric power apparatus consists of a converter circuit A, a smoothing circuit B and an inverter circuit C. A single-phase AC voltage for the apparatus is supplied to AC power input parts. And the DC voltage produced through the converter circuit A and the smoothing circuit B is converted to AC electric power having a predetermined voltage and frequency by the inverter circuit C, and is then output. In this inverter circuit, PWM control is performed. Moreover, since the converter circuit A has two diodes 1 and the inverter circuit C has two switching elements 3 so that each of these circuits consists of a half-bridge circuit, the number of the components needed for the circuit can be reduced effectively.
