Title: Polarization hologram lens, optical pickup, information reproducing device and information recorder
Inventor: KIKUCHI IKUYA
IPC: G11B7/1378
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup capable of being shared by the optical disks of different substrate thickness or recording density by using a polarization hologram lens and an information reproducing device or the like using the optical pickup. SOLUTION: In the case that a light beam made incident on this polarization hologram lens 6 is a normal light beam, since it is not diffracted, it is converted to the optical disk by a high numerical aperture through an objective lens 7. On the other hand when the light beam is an abnormal light beam, it is passed through the non-hologram area 6a of the center part of the polarization hologram lens 6 as it is and converged to the optical disk by a low numerical aperture. In the meantime, in a peripheral hologram area 6b, as the result of being diffracted, since positive primary diffracted light is converged in front of the optical disk and negative primary diffracted light is converged at the distant part of the optical disk through the objective lens 7, they are both turned to a defocus state.  Thus, this small-sized, light-weight and easily manufacturable optical pickup capable of being shared by the optical disks of the different substrate thickness or the like is realized.

Abstract: PURPOSE:To prevent the failure in ink discharge caused by the application of bubbles to the rear end of a liquid path (a liquid chamber side), by a method wherein an air chamber mainly composed of a container connecting a liquid chamber and at least partially consisting of a flexible material is provided outside the liquid chamber. CONSTITUTION:An air chamber 1 is compressed by an air chamber compressing fixture 8. After that, an ink sucking cap 9 connecting to a sucking pump is brought into close contact with a front face plate 10, and an ink is sucked from orifices. When the compressing fixture 8 is returned to an original position while an ink is sucked, the air chamber is restored to an original shape due to its restoring force. At this time, the inside of a liquid chamber and the air chamber becomes in negative-pressure states, and the ink is fully loaded in the liquid chamber and further reaches to a part of the air chamber 1. After that, a sucking action is stopped. The capacity of the air chamber is preferably approximately the same as that of the liquid chamber. As the air chamber, a container using a flexible material such as a plastic material, e.g. polyethylene, and a rubber material and having a wall thickness of the order of 0.1mm is preferably used. In addition, as the position for connecting the air chamber to the liquid chamber, the position allowing the bubbles in the liquid chamber to often remain is desirably determined.
