| 20090290005 | Liquid Container, and Method for Manufacturing the Same - A liquid container includes a container body having a fluid channel forming portion for forming a fluid channel in which a liquid flows, a sensor member having a sensor and a film that is adapted to fix the sensor member to the container body. The fluid channel forming portion has a container side opening section opened so as to face the sensor member and an outer peripheral portion disposed so as to surround the container side opening section, the film is adapted to seal a portion between an outer edge portion of the sensor member and the outer peripheral portion of the fluid channel forming portion, and the outer peripheral portion has an elastically deformable portion that allows the sensor member to move in a direction away from the container side opening section. | 11-26-2009 |

| 20080238956 | LIQUID DETECTION DEVICE, LIQUID CONTAINER USING THE SAME, AND METHOD OF PRODUCING LIQUID DETECTION DEVICE - A liquid detection device includes a casing main body in which a passage is formed and exposed in an opening, a sensor base that is disposed to face the passage of the casing main body, a sensor chip provided on the sensor base, a film that seals the opening in which the sensor base is held, and a partition wall that divides the passage into an upstream side and an downstream side. The sensor chip has a sensor cavity, and the sensor base has a first hole that guides a liquid from the upstream side to the sensor cavity, and a second hole that guides the liquid from the sensor cavity to the downstream side. The sensor base can come into contact with the casing main body through only the partition wall in a depth direction of the opening. | 10-02-2008 |

| 20110026040 | BATTERLESS ABSOLUTE ENCODER - A batteryless absolute encoder determines the accuracy of absolute position information to be output when electric power is turned on and outputs an alarm signal in the case of abnormality. The batteryless absolute encoder includes an absolute position computing section, an absolute position storing section, and a determining section. The absolute position computing section computes the absolute position of a spindle to be detected, including the number of revolutions of the spindle, on the basis of detection signals output from four reluctance resolvers. The absolute position storing section stores the absolute position output from the absolute position computing section when electric power is turned off. The determining section compares an absolute position output from the absolute position computing section when electric power is turned on and the stored absolute position and outputs an alarm signal if a difference between the two absolute positions is larger than a predetermined value. | 02-03-2011 |
| 20110115481 | MAGNETIC ABSOLUTE ENCODER - A magnetic absolute encoder with enhanced resolution is provided. A first cycle determining section | 05-19-2011 |
