Abstract: PURPOSE:To modulate the light in a high speed without requiring the dependency upon the plane of light polarization, by providing an electrode in an electrooptic optical deflecting element to irradiate the light from an optical fiber to an optical modulating element directly through a lens. CONSTITUTION:Two lenses 6 and 6' are installed under an optimum optical coupling condition between a pair of optical fibers, at least, which have end faces are shaped into a recess or projection, for example, between optical fiber bundles 7 and 7' consisting of fiber cores (a) and (b) and fiber cores (c) and (d), respectively, and an electrooptical optical deflecting crystal substrate 5 is installed on the light path between lenses 6 and 6'. When voltages are applied to electrodes 8 and 8' buried in this crystal substrate 5, a refractive index inclination is generated by the density distribution of lines of electric force to deflect the incident light, and thus, the light from the fiber core (a) is made incident to the fiber core (d) or the fiber core (c) to be modulated.

Title: Multi-layer build-up welding method
Inventor: KANETANI FUMIYOSHI
IPC: B23K9/16
Filed: 1982-10-26
Abstract: PURPOSE:To improve welding efficiency in a TIG welding method by controlling the voltage in the drooping characteristic of DC to a constant voltage thereby maintaining a specified arc length and progressing smoothly multi-layer build- up welding without interruption. CONSTITUTION:The voltage between a welding torch 2 and a base material 3 is detected by a voltage detector 1, and the difference DELTAV from a reference voltage V0 is detected by a comparator. The torch 2 is moved vertically according to said value so that the difference DELTAV is compensated always to 0. If the voltage is made constant in the drooping characteristic region of DC, the current stabilizes and the arc length is made constant, whereby the welding by the stable input is accomplished. The need for a gap adjustment by the arc extinguishing at every pass in multi-layer build-up welding is eliminated and since the multi- layer build-up welding is performed continuously, working efficiency is improved.

Title: Digital signal processing processor
Inventor: KAKISHITA MASAHIRO
IPC: G10H7/08
Filed: 1991-07-04
Abstract: PURPOSE:To vary a coefficient with lapse of time without placing any burden on an external processor not a microprogram. CONSTITUTION:A microprogram storage means 32 is stored with the function of the digital signal processing processor(DSP) 17, i.e., a microprogram which prescribes algorithm. A coefficient interpolating means 37 performs specific interpolative arithmetic based upon a 1st coefficient, given by the external processor 10 or microprogram, as a command to generate 2nd coefficients in order by this interpolative arithmetic. A coefficient utilizing means 33 performs digital signal arithmetic processing corresponding to the algorithm prescribed by the microprogram while utilizing the 2nd coefficients. Therefore, the external processor 10 or microprogram only supplies the 1st coefficient merely as the command to the coefficient interpolating means and the external processor 10 or microprogram itself need not perform the interpolative arithmetic processing.

Title: Thin film transistor and its manufacture
Inventor: SHIMADA YOSHIHIRO
IPC: H01L29/78
Filed: 1992-07-16
Abstract: PURPOSE:To reduce the size of a thin film transistor and, at the same time, to sharply improve the performance of the transistor by reducing its parasitic capacity. CONSTITUTION:Since the end sections of a source and drain electrodes 08 and 109 are not on a semiconductor film 104, the end sections of n<+>-type semiconductor films 106 and 107 and those of the electrodes 108 and 109 can be removed simultaneously. As a result, the mask margin which has been required in the conventional method, because the method uses two masks, becomes zero. Moreover, since the films 106 and 107 are formed in one semiconductor film as a source and drain by self-aligning the semiconductor film to an etching stopper 105, the areas of the junctions between the film 104 and the films 106 and 107 where parasitic capacitances are generated are very small as compared with the conventional example.

Title: Color image display method
Inventor: KANEKO SHUZO
IPC: G09F9/00
Filed: 1988-07-30
Abstract: PURPOSE:To obtain a sharp image by forming a mirror image on an image forming medium and displaying the image from the transparent substrate side of the image forming medium. CONSTITUTION:A color filter and a polymer liquid crystal layer which are aligned to each other are irradiated with the use of an optical system projecting the light of back lights having directivity in a diagonal direction. As a result, a color (indicated by R in the figure) which passes almost linearly through the transparent parts of the polymer liquid crystal layer does not come into the field of view, while colors (indicated by G and B in the figure) made incident on scattering parts are scattered so that scattered light is mixed and viewed clearly as a cyan color. When no transparent parts is formed and the scattering part is formed over the polymer liquid crystal layer, white color is viewed. In addition, when an optical system which does not project light with directivity in the diagonal direction but makes light incident almost vertically is used for a back light optical system, similar colors can be viewed by locating a viewpoint in a position away from a front. Thus, by performing positional conversion into contrast for a color image to be recorded it as a mirror image, and combining it with the color filter, the sharp image can be obtained.
