Title: Writing instrument
Inventor: HORI JIRO
IPC: B43K8/04
Filed: 1993-05-13
Abstract: PURPOSE:To reduce the resistance of a channel and to enhance reliability of an operation and a response to a pressure change, etc., by forming another passage from an ink supply passage, and arranging a capillary flow passage communicating an ink storage chamber with a feeder chamber. CONSTITUTION:Ink in an ink storage chamber 22 is supplied to a nit 24 through an ink supply passage 29, and the ink is held in a capillary flow passage 31 by a capillary force. Accordingly, the passage 31 becomes a state sealed by the force of the ink, and when a pressure in the chamber 22 is substantially equal to the atmospheric pressure, the ink is not fed into the chamber 26. If a temperature rises, the air in the chamber 22 is expanded to raise the pressure in the chamber 22, the ink is fed to the chamber 26 through the passage 31 to compensate a pressure rise in the chamber 22, thereby maintaining the inner pressure constant.

IPC: H04N19/625
Filed: 1990-04-27
Abstract: PURPOSE:To restore a screen area to be restored even when only one part in a sync block can be taken out by arranging a low band part among orthogonally transformed-encoded codes at the front part of the sync block. CONSTITUTION:The restoration of a video signal as a special reproducing picture is attained on a sync block of which the whole is included in a range able to be scanned by a reproducing head. However, data arrangement within the sync block is made that the low band part 71 of a code orthogonal- conversion-encoded at the front part of the sync block is arranged to attain the restoration of the video signal also on a sync block 6 unable to restore the video signal. Accordingly, the video signal can be restored only by SYNC, ID and the low band part 71 in the sync block. Thus, even when only one part in the video-recorded sync block can be taken out, the whole screen area restored by video data in the sync block is not made unable to be restored, the more screen area is restored and picture quality degradation is eliminated.
