20080209972 | RADIOACTIVE SUBSTANCE CONTAINER, MANUFACTURING APPARATUS THEREOF AND MANUFACTURING METHOD THEREOF - In the metal billet to be used for hot dilation forming, a forward side with respect to the pressing direction has a quadrate section and its diagonal length is not more than an inner diameter of a container. Moreover, a backward side with respect to the pressing direction has a circular section and its diameter is substantially same as the inner diameter of the container. The metal billet is heated to a temperature suitable for press working and is set into a container for press forming. While a center of a workpiece of the metal billet is being bored by a boring punch to be operated by a pressing machine, the metal billet is hot-dilated so that a bottomed container for a cask is formed. | 09-04-2008 |

20080250816 | Optical fiber, optical fiber connecting method, and optical connector - An optical fiber which, at an optical fiber connecting end having a plurality of voids around the periphery of a core, has a light-permeable substance, such as a resin or glass whose refractive index is lower than that of quartz type substances, filled in the voids adjacent to the connecting end. An optical fiber connecting section where an optical fiber having a plurality of voids in a clad around the periphery of a core is connected to another optical fiber, wherein the optical fiber is connected end-to-end to aforesaid another optical fiber through a refractive index matching agent whose refractive index at the minimum temperature in actual use is lower than that of the core. | 10-16-2008 |

20090078071 | TRANSMISSION - Provided is a transmission in which gears of a first-speed to a seventh-speed shift stages are relatively rotatably supported on an outer circumference of a rotational shaft with clutch mechanisms. A desired shift stage is achieved by selectively engaging or disengaging the clutch mechanisms by moving, in an axial direction, the slide cam disposed inside the rotational shaft. While the slide cam is formed into a cylindrical shape, a cylinder, as an actuator, is disposed in a space inside the cylindrical slide cam. Oil chambers are formed inside the cylinder respectively to sandwich a piston therebetween. Oil pressure is supplied to the oil chambers to move the slide cam in the axial direction. The provided transmission with such a configuration has a smaller size than a transmission with the actuator disposed outside the slide cam. | 03-26-2009 |
20090078073 | TRANSMISSION AND METHOD OF UP-SHIFTING FOR TRANSMISSION - The driving force can be transmitted at the time of both acceleration and deceleration in an engaged state where a first engagement face of a strut is forced to protrude inside a cutaway of a gear. The driving force is transmitted at the time of acceleration and the transmission of the driving force can be cut off at the time of deceleration in a one-way state where the first engagement face of the strut and the cutaway of the gear are made either to engage with or to disengage from each other in accordance with the rotational direction of the gear relative to the rotational shaft. The transmission of the driving force can be cut off at the time of both acceleration and deceleration in a disengaged state where the first engagement face of the strut is forced to withdraw from the cutaway of the gear. In addition, the decreasing of the transmission efficiency caused by friction between the strut and the gear can be prevented. | 03-26-2009 |
