Title: Cap and liquid droplet jetting device
Inventor: UMEDA RYUICHIRO
IPC: B41J2/165
Filed: 2004-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cap capable of closing a nozzle in an airtight manner by two ways and a liquid droplet jetting device using the cap without increasing the cost and the device in size.  <P>SOLUTION: When the cap 64 is pressed against a nozzle face 29 such that the nozzle 33 is positioned on the center of a cover section 643 (b), a lip 642 is continuously brought into intimate contact with a periphery of an opening section of the nozzle 33, and then a sealed space can be formed on the surface of the opening section of the nozzle 33. While the ink in the nozzle 33 can be dried when the nozzle 33 is left in the above condition for a long time period, the cap 64 is not at all brought into contact with the surface of the opening section so that the ejecting operation of the ink is not influenced thereby. When the cap 64 is pressed against the nozzle face 29 such that the nozzle 33 is positioned on the center of an intimate contact section 641 (c), the intimate contact section 641 in a roughly planar shape closes the opening section of the nozzle 33 in an airtight manner. At that time, the effectiveness of preventing the drying of the ink is high, but the ejecting operation just after the cap 64 is separated therefrom is influenced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Optical disk system and tracking control method
Inventor: ARIKAWA YOSHIROU
IPC: G11B7/095
Filed: 2004-02-05
Abstract: <P>PROBLEM TO BE SOLVED: To make tracking control with high precision by detecting direct current fluctuations of a push pull signal by disk eccentricity with high precision.  <P>SOLUTION: Time constants of hold circuits 103 and 104 for detecting a top level St and a bottom level Sb of a push pull signal is controlled by a time constant control signal. Traverse amplitude and a traverse offset are calculated by using digital signals of the signal St which shows the top level and the signal Sb which shows the bottom level. The traverse offset Sf is used to compensate fluctuations of a direct current level resulting from the disk eccentricity. An interrupt processing section 124 uses a tracks count signal Sc and a frequency count signal Sd, detects the number of tracks which crossed a reading spot during one revolution of a spindle motor 109, and calculates the traverse frequency with one revolution cycle and the traverse number. The higher the traverse frequency becomes, the smaller the time constant becomes.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
