  • Publication number: 20110068890
    Abstract: This invention relates to a method for thin film device. The method for manufacturing a thin film negative temperature coefficient thermistor is disclosed. It includes selecting a substrate, a temperature-sensitive layer, inner electrodes, a protective layer and end electrodes. The temperature-sensitive layer is an NTC thin film, the inner electrodes have a comb-shaped structure. The resistance value of the present invention can be regulated by changing material composition and the width, gap, length of comb-shaped electrodes, which are not influenced by the error of the thermistor physical size. In present invention, a high temperature glaze is engaged to smooth the surface of cheaper ceramic substrates. This process reduces the manufacturing cost, improves the structure, enhances the reliability and the yield and thus expands the application scope of the NTC thin film thermistor chips. The invention has an industrial practicability.

  • Patent number: 5825023
    Abstract: An auto-focus laser incremental encoder for measuring linear or rotary motion or position of an object is described. An optical read head focuses three laser beams on the surface of a scaling grating. The grating is a reflection type grating where the height difference between adjacent pixels is one quarter of the wavelength of the laser light whereby the pitch of the grating can be detected by interferometric reflection. There are two sections of grating displaced with respect to each other so that a direction of movement can be readily determined. The third beam acts to provide an autofocus and is reflected from a smooth part of the grating between the two sections of reflective grating.

  • Patent number: 5757491
    Abstract: A laser interferometer system in particular for measuring the straightness of an object is described. This interferometer employs triangular prisms to refract the laser beams by certain angles with respect to the principal axis of the incident beam. Two configurations are described. One is for high accuracy in short range measurements, the other can handle long range measurements with high resolution that is not related to the range. For the latter the interferometer comprises a laser source, a beam splitter, a plane reflector, two first triangular prisms, a second prism, a right angle prism reflector and a detector system. The second prism and the right-angle prism reflector are integrated into one body to form a movable component and are attached to the object to be measured.
