Title: Apparatus for detecting quantity of ink remaining in recording apparatus or the like
Inventor: KUBO TOMOYUKI
IPC: B41J2/175
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To surely recognize a liquid level of ink in an ink cartridge and correctly detect a quantity of remaining ink in an apparatus for detecting the quantity of remaining ink in a recording apparatus or the like. SOLUTION: When a predetermined time passes (S2) after a carriage stops at a quantity detection position (YES in S1), a quantity of remaining ink is detected by an ink quantity detection sensor (S3), based on which the presence/ absence of the quantity of remaining ink in an ink cartridge is judged (S4). The ink is thus prevented from being detected in a state where the ink waves in the ink cartridge immediately after the carriage stops scanning and the quantity of remaining ink is detected in a state where the waving of the ink is brought to the end. A liquid level of ink is surely recognized, thereby enabling correct detection for the quantity of remaining ink.

When a coil 23a is energized, a plunger 23c is attracted downwardly by a coil magnetic field, an inlet port 23e and an outlet port 23f are opened to communicate with each other. When an ink injection signal becomes high level, the ink pressure of an accumulator 4 is applied to the head 5. A sinusoidal wave synchronized with an excitation reference pulse from an excitation signal generator 15 is applied to the vibrator 5 of the head 5, the ink injected from the head 5 is isolated into ink particles. When the signal becomes low level, the ink supply to the head 5 is interrupted. When the vibrator 5a is returned to the original position, the ink drop can be prevented by the contraction of an ink tube.

Title: Electrode of high-temperature ptc ceramics and method of producing the same
Inventor: KAIMOTO TAKASHI
IPC: H01C7/02
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain stable characteristics, even at higher temperature use than a specified temperature for a long period of time by using aluminum or an aluminum alloy as an electrode material to form the electrode by heating, while performing thermal spraying to a sintered surface. SOLUTION: An electrode is formed by thermally spraying aluminum or an aluminum alloy to a PTC ceramics 1 having 300 deg.C or higher Curie point, and sufficient anchor effect is easily obtained, when surface roughness of the PTC ceramics formed with the electrode is 1 μm or more. Since Pb is vaporized from the surface in sintering at 300 deg.C or higher Curie point, which is increased in quantity within the material as rising temperature, the electrode can be formed easily on the surface by thermal spraying. Also, since electrode layers 2a and 2b are adhered to the PTC ceramics 1 by adhesion properties due to anchor effect, the adhesion properties is not changed even under a high temperature environment of use, the sintered surface has stable properties.
