摘要： PURPOSE:To realize excellent oil lubrication by a structure wherein a guide ring is made of a material, the thermal expansion coefficient of which is larger than that of an shaft collar, and the shaft collar is cylindrically supported. CONSTITUTION:Because the thermal expansion coefficient of the guide ring 5a is larger than that of the shaft collar 2, the thermal elongation of the guide ring 5a exceeds the sum of the thermal elongation of the outer diametral surface and the displacement by expansion due to the centrifugal force of the shaft collar 2. Consequently, the radial and outward thermal elongation of a guide metal 3 due to thermal expansion becomes so large that the metal gap dimension between the shaft coller 2 and the guide metal 3, which has caused trouble heretofore, scarecely diminishes during running, resulting in enablingh to maintain excellent oil lubrication between the shaft collar 2 and the guide metal 3.

摘要： PURPOSE:To enhance the stability of a vertical shaft type water-turbine generator by securing a bracket arm which holds an upper guide bearing to a peripheral wall with a device having small radial rigidity and large tangential rigidity, thereby absorbing the thermal expansion of the arm and suppressing the unbalance of a rotor. CONSTITUTION:The upper part of a rotational shaft 1 of an electromagnetic device having a rotor 8 and a stator 9 is journaled by a guide bearing 3, which is held by a bracket arm 5, and the end of the arm 5 is secured to the floor 13 of the peripheral concrete wall with a fastener 27. In this case, the fastener 27 is made of a supporting plate 29 having broad width and small thickness and is secured so as to acommodate small radial rigidity and large tangential rigidity of the arm 5. In this manner, the thermal expansion of the bracket arm is absorbed, and the rotor 8 can endure against the tangential force due to the unbalance of the rotor 8, thereby improving the stability.

摘要： PURPOSE:To minimize the substantial areas of pads for ultrasonic bonding, and to improve the degree of integration by rectangularly forming the bonding pads shaped around a chip and arranging the pads so that the long side directions extend toward the central sections of the pads. CONSTITUTION:The rectangular Al pads 11, 12... 1n are mounted to an outer circumferential section of an element region 3 of the Si chip 2. The longitudinal and lateral length p, q of each pad are set to approximately threefold and octuple of a diameter d of a wire 4, and the longitudinal directions are all disposed toward the center o of the chip 2. When bonding, the chip 2 is turned successively so as to conform the longitudinal directions of the wires 4, the direction of vibration of ultrasonic waves, and the longitudinal directions of the pads, and the pads are positioned in the x and y directions. Accordingly, the protrusion of the bonding sections 4a outside the pads can be prevented without enlarging the areas of the pads to value more than required, and the integrated circuit can be integrated to a high degree.

CONSTITUTION: A belly side boss 14 which runs along a belly side and a back side boss 15 which runs along a back side are formed at a blade face 4 of an adjoining rotary blade 2, and a connector 23 is inserted in to a hole 17 formed at each boss 14, 15. The hole 17 of the belly side boss 14 is made of an oblong 19 and a semi-circle 26 of a larger diameter and a jaw 21 which connects both parts 19 and 20, while the semi-circle 20 is situated at the exit side of a flow passage between blades. While the hole 17 of the back side boss 15 is similarly shaped, the semi-circle 20 is situated at the entry side of the flow passage between blades in this case. The connector 23 consists of a pillar-shaped part 35 having more or less the same section as that of the above-mentioned hole 17 and of a blade 28 with a semi-circule section; a tapered face 29 set at the blade 28 of each connector 23 links bosses 14, 15.

摘要： PURPOSE:To maintain preferably oil lubrication of a rotary machine by supporting a guide frame at the axial center of a thin cylinder which is mounted between the bore ends of upper and lower circular wheels, thereby preventing the size in the gap of bearings from decreasing at the operating time. CONSTITUTION:Upper and lower ends of a thin cylinder 24 are respectively rigidly clamped with bolts 26 at the bore side ends between upper and lower circular wheels 14 and 15, and a guide frame 5 is mounted at the axial center of the cylinder 24. Since the radial thermal elongation of the frame 5 is absorbed by the radial deformation at the axial center of the cylinder 24 but the radial rigidity of the cylinder 24 is small due to reduced thickness, the frame 5 is not almost affected by the restriction but thermally elongated until it contacts with the bore of the cylinder 25. Accordingly, the size in the metal gap between a shaft collar 2 and a guide bearing 3 does not almost decrease even at the operating time, thereby maintaining preferable oil lubrication.
摘要翻译：目的：通过在安装在上下圆轮的孔端之间的薄圆筒的轴向中心处支撑引导框架来保持旋转机械的油润滑，从而防止轴承间隙中的尺寸在操作时间。构成：细圆筒24的上端和下端分别在上和下圆形轮14和15之间的孔侧端处用螺栓26刚性地夹紧，并且引导框架5安装在圆柱体24的轴向中心。由于框架5的径向热伸长被圆柱体24的轴向中心处的径向变形所吸收，但由于厚度减小，气缸24的径向刚度较小，所以框架5几乎不受限制但受热拉伸直到它与圆筒25的孔接触。因此，即使在操作时间，轴套2和导向轴承3之间的金属间隙中的尺寸也几乎不降低，从而保持优选的油润滑。

摘要： PURPOSE:To smoothly support the weight of a bracket arm for a water-wheel generator by supporting the bracket arm with a supporting trestle and a stator trestle. CONSTITUTION:A vertical rotational shaft 1 which is installed in a concrete wall 2 and which has a water wheel at the lower part is provided. There are provided electromagnetic units 3, 4 provided on the shaft 1, a guide bearing 5 provided on the top of the units 3, 4 and supporting the shaft, and a bracket 6 having a bracket arm 7 radially projected, and the weight of the arm 7 is supported by a supporting unit 13 provided in a concrete wall. The unit 13 is formed of a stator trestle 11 for the units 3, 4 and a supporting trestle 12 provided at the outer radial side of the stator trestle. In this manner the deflecting deformation by the bending moment to the inner radial side of the stator trestle can be suppressed by the supporting trestle, and the weight of the arm can be supported without increasing the stator trestle.
