摘要： A residual stress improving apparatus for piping, which can heat an outer peripheral surface of piping to reduce (including eliminate) the residual stress of the piping is provided. The apparatus has a laser head portion, and circumferential direction moving mechanism composed of a ring rail and a rotational travel bogie. Further, the apparatus may adjust the reflection direction of laser light so that the laser light reflected by the outer peripheral surface of the piping does not return to the laser head, and adjust the delivery direction of the laser light so that the outer peripheral surface of the bending pipe portion located forwardly, in the pipe axis direction, of the laser head is irradiated with the laser light.

摘要： The intensity of light penetrating an X-ray film being viewed is automatically maintained at a preset, adjustable, eye comfort level. A photosensor detects the average light level on the observer side, and its output controls the charging time of a capacitor coupled to the emitter of a unijunction transistor. When the capacitor reaches a predetermined voltage it fires the transistor and dumps its charge through a pulse generator which in turn triggers a gated semiconductor connected in series with the viewer light source. The period between successive firing cycles is proportional to the penetrating light level. Thus, if the light level increases, as when a relatively transparent film negative is inserted in the viewer or when a negative is removed, the capacitor charging time increases, the firing period increases, and the light source intensity therefore decreases to restore the preset level of light penetration.
摘要翻译：被观察的穿透X射线胶片的光的强度自动保持在预设的可调节的眼睛舒适度。光电传感器检测观测器侧的平均光级，其输出控制耦合到单结晶体管的发射极的电容器的充电时间。当电容器达到预定电压时，它激发晶体管并将其电荷转移通过脉冲发生器，脉冲发生器又触发与观察者光源串联连接的门控半导体。连续点火周期之间的周期与穿透光水平成比例。因此，如果光水平增加，则当在观察者中插入相对透明的胶片负片或者当消除阴影时，电容器充电时间增加，触发周期增加，并且光源强度因此降低以恢复预设电平的光线渗透。

摘要： A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft. When the turbine is not operated, the top ends of the leaves contact the rotation shaft again due to the elastic restoring force of the leaves.

摘要： Video signals representative of photographic images which are stored in a plurality of substantially equally dimensioned frames in horizontal and vertical positions are produced by picking up the images. A first signal indicative of a horizontal/vertical position and a top-bottom orientation of the photographic image stored in any of the frames is entered. The photographic image is rotated relatively in response to the first signal. For a vertically positioned image, a video signal is produced which is representative of the image with a magnification which is smaller than that of a horizontally positioned image. Such a procedure provides a video signal which represents an image in a non-inverted top-bottom orientation without any essential portions of the image being omitted.
