摘要:
The present invention allows the detection of ink in a printing head that can be widely applied to various printing systems by significantly simplifying its configuration. There are a heater for supplying an energy to eject ink, a driver for driving the heater, and a detection electrode capable of detecting a voltage variation that arises between the heater and the driver and that depends on the driving of the heater. Furthermore, an insulating film that covers the surface of the detection electrode protects the detection electrode from chemical or physical change. Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element and another signal source improve the accuracy of ink detection. A drive pulse which is insufficient to eject ink may be supplied to the heater to improve the accuracy of ink detection.

In the present invention, the minimum necessary consumption of ink can recover the channel miss state of the plurality of nozzles. The present invention provides a recovery processing method of an ink jet printing apparatus for forming images using a print head having a plurality of nozzles for ejecting ink droplets. The method comprises a first step for detecting channel miss state of said plurality of nozzles, and a second step for executing at least one of different recovery processes depending on the channel miss states of said plurality of nozzles detected in the first step.

A fuel supply apparatus for an internal combustion engine includes: a feed pump capable of feeding a fuel of the internal combustion engine; a high pressure fuel pump that pressurizes the fuel fed from the feed pump; and a second injector that supplies the pressurized high-pressure fuel to the internal combustion engine selectively. An ECU of the fuel supply apparatus includes: a pulsation width detection unit that detects a pulsation width in a pressure of the fuel fed from the feed pump to the high pressure fuel pump; and a feeding condition determination unit that determines that a condition variation causing fuel vapor to form in the fuel fed to the high pressure fuel pump has occurred when the pulsation width detected by the pulsation width detection unit falls rapidly to a preset threshold variation width.

Provided is an ocular optical system, which permits a measuring beam scanned by two scanning units disposed close to each other to enter an anterior ocular segment of an eye to be inspected and to irradiate a fundus. The ocular optical system includes an optical unit which is disposed at a position of an intermediate image, which is optically conjugate to the fundus, and has a surface having different optical powers corresponding to scan directions of the two scanning units.

The image display apparatus forms first and second images in mutually different viewing angle areas to display a combined (joined) image. The apparatus includes first and second image-forming elements respectively forming first and second original images, a first optical system reflecting a first light flux from the first image-forming element at least twice to introduce the first light flux to an exit pupil, and a second optical system reflecting a second light flux from the second image-forming element at least twice to introduce the second light flux to the first optical system. The first optical system introduces the first light flux and the second light flux from the second optical system to the exit pupil such that the first and second images respectively corresponding to the first and second original images are formed in the mutually different viewing angle areas in a first cross section.
