    • An air cylinder raising and lowering a pickup head for holding an IC device in an electronic device test apparatus, the air cylinder includes a cylinder tube; a piston; a first hollow chamber formed below the piston; a second hollow chamber formed above the piston and being larger than the first hollow chamber in terms of a pressure receiving area of the piston; and a rod with one end coupled with the piston and the other end coupled with the pickup head. The first hollow chamber is connected to the air feed device via a first feed system in which the air feed is secured even if the electric power supply of the electronic device test apparatus is cut off, and the second hollow chamber is connected to the air feed device via a second feed system having a shutoff valve.

    • The optical information recording and reproducing device utilizing holography requires the optical system to generate the signal beam and the reference beam to be irradiated to the holographic storage medium as well as another optical system to generate the curing light beam to be irradiated to the holographic storage medium. Furthermore, from the viewpoint of backward compatibility, if the same device is used for recording or reproduction on the conventional optical discs represented by Blu-ray Disc, another optical system adaptable to recording and reproduction on these optical disks is required. This means the optical system configurations become complicated and larger in size. One solution for downsizing is to use the reference beam also as the curing light beam. Another way is sharing of optical path for curing light beam and for the reference beam. Furthermore, it is possible to share the light source for generating the curing light beam and for generating the recording or reproducing light beam. In such way, optical system configurations become simple.
    • 利用全息术的光学信息记录和再现装置需要光学系统产生要照射到全息存储介质的信号光束和参考光束以及另一个光学系统,以产生照射到全息存储介质的固化光束 。 此外,从向后兼容性的观点出发,如果在由蓝光光盘所表示的传统光盘上使用相同的设备进行记录或再现,则需要在这些光盘上适用于记录和再现的另一光学系统。 这意味着光学系统的配置变得复杂并且尺寸更大。 用于小型化的一个解决方案是使用参考光束也作为固化光束。 另一种方式是共享用于固化光束和参考光束的光路。 此外,可以共享用于产生固化光束的光源和用于产生记录或再现光束。 以这种方式,光学系统配置变得简单。
