IPC: G11B7/09
Filed: 1986-08-13
Abstract: PURPOSE:To prevent a track jump due to the defect of an optical disk and track jump due to vibration by increasing the attenuation of an attenuation means so as to reduce the gain of a tracking servo loop when a defect detection means detects the defect of an optical disk. CONSTITUTION:A flaw detection circuit 40, based on the output signal (n) of a waveform shaping circuit 11, brings its output signal (q) to level '1' only when a local defect such as a flaw or stain on the optical disk 1. The output signal (q) of the circuit 40 is fed to the switch SW of an attenuator 37 and when a flaw or the like is detected by the circuit 40, the attenuation of the attenuator 37 is large, the gain of the tracking servo loop is decreased and if no flaw or the like is detected, the attenuation of the attenuator 37 is decreased and the tracking servo loop gain is increased. In selecting the gain of the tracking loop to be large. the track ump due to vibration hardly takes place and when the gain is taken small, the track jump due to the local defect of the disk 1 such as flaw hardly takes place.

Title: Ink cartridge for ink jet and ink jet recording device
Inventor: TAJIMA HIRONORI
IPC: B41J2/175
Filed: 1993-08-02
Abstract: PURPOSE:To obtain a highly reliable ink cartridge which is almost free from ink leakage through an atmospheric connection orifice by forming the atmospheric connection orifice in such a manner that it protrudes an annular projection and the length of an outermost projection is more than twice of that of an innermost projection. CONSTITUTION:A gap is formed between a negative pressure absorptive member (absorbent) and the projection of an atmospheric connection orifice and consequently, an ink leakage hardly generates by making the length of an outer annular projection at least 2a, if the length (a) of the atmospheric communication orifice A which protrudes into a negative pressure generating member is given as (a). In addition, the outer annular projection is provided so that it does not come into contact with the projection of the atmospheric connection orifice. Further, ink is held in a space between both projection, if the ink leaks out of the negative pressure generating member, and consequently the leakage of ink from the atmospheric connection orifice is prevented from occurring with increased reliability. In this case, the gap between both annular projections is wide enough not to allow the ink which is resident in the gap to leak out of the atmospheric connection orifice by capillarity.
