Abstract: PURPOSE:To execute stable driving even if the temp. of the use environment changes by detecting the temp. of a display layer consisting of a high-polymer liquid crystal compsn. which exhibits a ferroelectric property and changing the driving signal for driving the liquid crystal according to the detected temp. CONSTITUTION:In general, the rate of the polarization inversion of the high- polymer liquid crystal by the impression of an electric field thereto is low as the viscosity of the system increases with a decrease in temp. Such change in the reaction rate can be kept within a specified range by changing the driving voltage or driving frequency, etc., according to the temp. of the display layer. A temp. detecting part 6 is provided on the surface of one substrate 1 of the display device having the display layer 5 consisting of the high-polymer liquid crystal compsn. which exhibits the ferroelectric property between a pair of the substrates 1 and 1a and the temp. change detection signal 9 detected therein is introduced to a driving signal generating part 7. The driving signal 10 from the driving signal generating part 7 is passed through a segment side driving part 11 and a common side driving part 12, by which the voltage or driving frequency, etc., of striped electrodes 2, 2a are changed.

Abstract: PURPOSE:To eliminate the need for a driving IC to be exclusively used for gradation display and to deal with a change of the number of gradations by making gradation display by using a binary driving IC or a driving IC of simpli fied constitution and by external control of this driving IC. CONSTITUTION:The raster display time within respective frames is divided to plural m of blocks (sub-raster) varying in length. The brightness in the single raster is determined by the combination of m-pieces of the sub-rasters. The combinations of m-pieces of the sub-rasters are prepd. in n-ways in correspondence to n-pieces of the frames of the display units so that nXm-ways of the combinations of the display time are possible within the unit display time. Further, adjacent n-pieces of display dots are grouped as a unit display region and are so combined that n-ways of the sub-rasters are independently selected by every display dot within the unit display region. the average brightness difference within the unit display region of each of the respective frames between n-pieces of the frames is made 0 by this means.

Abstract: PURPOSE:To easily form a chip breaker and lower a manufacturing cost down to the cost of a tool in which no breaker is provided by providing the chip breaker not on a cutting tool piece but on a shank which is formed with a sintered hard alloy, etc. CONSTITUTION:A cutting edge piece 2 is formed in such a way that the top face 2a thereof agrees with the top face of a shank 1 in a condition of the piece 2 being installed on the shank 1, cutting machining is given to the side face 2b thereof with the piece 2 being joined to the shank 1, and a cutting edge is formed on a crossing ridge between both faces 2a, 2b. When a chip produced by the cutting edge flows out on a rake face on the top faces of the cutting edge piece 2 and the shank 1, the chip is brought into contact with projections 4, 5 on the top face of the shank 1 and subjected to braking force and deformed or divided. Since the cutting edge used here is wholly covered with the cutting edge piece of a hard sintered body, an end abrasion property is not lowered obtaining a tool life similar to the conventional one in which the whole corner portions are covered with cutting edge pieces. Also, the projections 4, 5 can be formed on the shank 1 of sintered hard alloy merely by providing projections on a metal mold, enabling manufacture at the same cost as for these having no projections.

Filed: 1991-12-19
Abstract: PURPOSE: To improve linearity of a stripe by deciding the inclination change value of a light source synthesizing a shutter period with the differentiation of a curvature equation with respect to time after the curvature equation in a panel is differentiated with respect to a short side axis. CONSTITUTION: A curvature equation of a panel 1 is differentiated with differentiators 21 and a differentiation function is generated. The value bent by an angle conversion part 22 at an origin point of panel 1 is generated as each X, Y, and Z coordinates and angle conversion values are generated. Moreover, a time function by a period of a shutter 3 is output from a time function part 23 and is synthesized to the angle conversion value, being output. The output value controls a drive of a cam axis by controlling a motor which drives a light source 7. Therefore, it is changed by the inclination θ of the light source 7 by each coordinate. That is, it is changed as the inclination of the light source 7 corresponds to curvatures in the panel, and a uniform quantity of light is exposed over all sections in non-spherical panel.  As a result, the linearity of the stripe is improved greatly and a black matrix is formed with a straight line.
