摘要： A bearing with an oil film thickness measuring device in which sensor portions at distal ends of four common optical fibers are connected to sensor mounting portions formed at four positions in an axial direction of a bearing body. A lubricating oil containing a fluorescent agent is supplied to a sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to an oil film on a sliding surface through each of sensor portions. Fluorescence generated by the fluorescent agent in the oil film, passing through a return-route optical fiber, is introduced into a photomultiplier tube, and is detected. Since the fluorescence intensity detected by the photomultiplier tube is proportional to the thickness of oil film, the absolute value of oil film thickness can be measured. In this case, the oil film thickness can be measured at four positions.

摘要： There is provided a method of working a plain bearing and a working apparatus of the plain bearing, which make it easy to perform working by forming a plurality of inclined surfaces of different angles in portions on both sides of the inner peripheral surface of the bearing alloy metal of the plain bearing in the axial direction thereof. In the working method and apparatus, a working holder 18 is provided which has a groove 20 extending on the inner peripheral surface in the peripheral direction and portions on both sides of the groove in the transverse direction formed in step-like shape, a half bearing 11 is housed in the working holder 18, and both ends of the half bearing 11 in the peripheral direction are pressed by use of pressing means 24. Then, the half bearing undergoes plastic deformation so as to be fitted into the groove and both sides of the half bearing in the axial direction thereof come into abutment with the edges 22, 23 of the step-like portions and are deformed in a polygonal line form. In this state, both ends of the half bearing 11 in the axial direction thereof are cut along one cylindrical surface by use of a broach 19. As a result, two inclined surfaces of different angles are continuously formed in the portions of both sides of the bearing alloy metal 13 of the half bearing in the axial direction thereof.

摘要： A sliding bearing comprises a back metal and a bearing alloy layer formed thereon, the thickness of the back metal gradually decreasing from the middle portion toward each axial end portion, and the thickness of the bearing alloy layer being increased at each axial end portion. The bearing alloy layer has a Young's modulus smaller than that of the back metal of steel plate and hence it is elastically deformed with greater ease, and therefore, particularly at the beginning of the use, the oil film pressure at each axial end portion becomes higher when misalignment takes place, with the result that the bearing alloy layer is elastically deformed in the direction of compression. In consequence, the oil film thickness at opposite end portions is increased to prevent rupture of oil film, thus avoiding occurrence of metal contact.
摘要翻译：滑动轴承包括背面金属和在其上形成的轴承合金层，背面金属的厚度从中间部分朝向每个轴向端部逐渐减小，并且轴承合金层的厚度在每个轴向端部处增加。轴承合金层的杨氏模量比钢板的背面金属的杨氏模量小，因此容易弹性变形，特别是在使用开始时，各轴端部的油膜压力变高当发生不对准时，结果轴承合金层在压缩方向上弹性变形。因此，相对端部的油膜厚度增加，以防止油膜破裂，从而避免金属接触的发生。

摘要： An airbag (18) made of metal is disposed between an edge portion (12a) of a windshield (12) of a vehicle and an outer panel (16), projecting toward an outside of a vehicle body beyond the edge portion (12a), of a front pillar (15). Thus, it is possible to install the airbag device without making large design changes to the existing structure of the vehicle body, and to prevent the external appearance from being deteriorated by the installation of the airbag device. Further, once the airbag (18) made of metal is deployed, the airbag does not shrink. Thus, it is possible not only to reduce the weight and costs by employing an inflator (19) with a smaller volume, but also to cause the airbag to exert a stable shock absorbing capability irrespective of the difference in the timing of the collision of a pedestrian. Further, a part of the airbag (18) is a garnish part (18a) forming an outer surface of the vehicle body in cooperation with the outer panel (16). Thus, it is possible to reduce the number of parts and costs by making the garnish part (18a) exert the garnish function.
摘要翻译：由金属制的气囊（18）设置在车辆的挡风玻璃（12）的边缘部分（12a）和外侧面板（16）之间，突出于车身外部超过边缘部分（12a），的前支柱（15）。因此，可以安装气囊装置而不会对现有的车体结构造成大的设计变化，并且通过安装气囊装置来防止外观恶化。此外，一旦展开了由金属制成的气囊（18），气囊就不会收缩。因此，不仅可以通过使用体积较小的充气机（19）来减轻重量和成本，而且可以使气囊发挥稳定的冲击吸收能力，而不管碰撞时间的差异如何行人。此外，气囊（18）的一部分是与外板（16）配合形成车体的外表面的装饰部（18a）。因此，可以通过使装饰部件（18a）施加装饰功能来减少部件数量和成本。

摘要： A first silicon containing film, an organic material film, a second silicon containing film are formed. The second silicon containing film is patterned to have a narrow width pattern and a wide width pattern. The organic material film is patterned to have a narrow width pattern and a wide width pattern. A side wall is formed on a side surface of the second silicon containing film and the organic material film by coating with a third silicon containing film. The narrow width pattern of the second silicon containing film is removed by using a mask that covers the second silicon containing film patterned to have a wide width pattern and the side wall. Finally, the organic material film is removed.

摘要： A signal can be detected based on a level slice system and detection delay time can be reduced by setting the recording density of a header field in a linear direction lower (coarse) than that of a user data recording field. Further, a signal can be detected based on the level slice system and detection delay time can be reduced by using a mark position form having a large detection margin as an information recording system of the header field. A readout error of a sector number due to a detection error is compensated for by recording address marks AM for attaining byte synchronization of the header field in both of a head portion and tail portion of information recorded in the header field.
