Abstract: A separation layer is provided on a substrate, and a thin film device, such as TFT, is formed thereon. Separation accelerating ions such as hydrogen ions are implanted into the separation layer in the course of the process for forming the thin film device. After the formation of the thin device, the thin film device is preferably joined to a transfer material through an adhesive layer, and irradiated with laser light from the substrate side. This causes separation in the separation layer by also using the action of the separation acceleration ions. The thin film device is separated from the substrate. This permits transfer of a desire thin film device to any substrate.

Abstract: Disclosed is a common voltage regulating circuit of a liquid crystal display device which can be adjusted by software, comprising: a pulse signal generating means for outputting a pulse width modulation signal in response to up/down signal for adjusting a common voltage; a smoothing means for smoothing a pulse width modulation signal to a direct current level provided from the pulse signal generating means; and an amplifying means for amplifying the signal smoothed by the smoothing means to a predetermined level and then outputting a common voltage signal Accordingly, since a common voltage can be adjusted by software, by means of a surplus pulse width modulation signal generated in an integrated board without installing a separate hardware, the common voltage can be easily adjusted. Further, since a variable resistor has not been used, not only manufacturing cost but also possibility of breakage can be reduced.

Abstract: Improved differential optical sensors are mounted at every intersection of the deflection planes of the ink droplets issued by a multi-nozzle printhead of a pagewidth ink jet printer. These sensors are located near the printing plane and gutters of the printer. They comprise first and second input apertures, each being coupled to a light source and fixedly located to direct beams of light to a confronting associated pair of output apertures. The input and output apertures are on opposite sides of the droplet deflection plane, and the input apertures are on opposite sides of a perpendicular line extending from the midpoint between the pair of output apertures. The light beams impinge the pair of output apertures thereby creating differentially detected zero-crossing optical axes at predetermined angles with respect to the perpendicular line therefrom.

Abstract: In accordance with illustrative embodiments of the present invention, data signals, particularly well logging data in analog or digital form, is recorded by a cathode ray tube recorder. A representation of the CRT beam is repetitively swept across a recording medium while being modulated with representations of the well logging signals. This modulation varies as a function of the rate of change of the well logging signals to produce an even density recording. Coding of the recording lines or traces and the areas between selected traces can be accomplished. This coding of the lines is also varied in dependence on the well logging signal rate of change to produce a uniform coding presentation. Depth information can be recorded on the recording medium by writing depth numbers and depth lines on the record medium. Moreover, a section by section visual presentation of the data can be produced while it is being recorded.
