Title: Electron emitting element, and electron source and image forming device employing the electron emitting element and manufacture thereof
Inventor: SHINJO KATSUHIKO
IPC: H01J9/02
Filed: 1995-03-13
Abstract: PURPOSE: To make electron emitting characteristics uniform while being free from adverse effects caused by the thickness of a thin film, fluctuations in resistance and differences in wiring resistance in the electron emitting element provided with a conductive film where an electron emitting section is interposed between electrodes. CONSTITUTION: In the electron emitting element, one electron electrode 401 is formed into a comb-tooth shape, and the opposite electron electrode 402 is formed straight. When voltage is applied thereto, electric fields are concentrated at comb-tooth tip end sections 404 in a thin film area 403, and an periodic field distribution is formed, which indicates the weakest strength of its electric field at its trough sections 405. When applied voltage is boosted, the electric field is divided at the comb-tooth end sections 404, however, the progress of dividing can be controlled to an area very close to the comb-tooth tip end sections as voltage is left as is. Moreover, one electron electrode 406 is formed identical in a shape to the aforesaid electrode, and the other opposite electron electrode 407 is inclined.  When voltage is applied thereto, the electric field strength of each comb-tooth tip end 409 becomes higher at a place where a distance between the electron electrodes is narrow.

Title: Detecting device for throttle valve opening degree of internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: G01B7/30
Filed: 1987-04-02
Abstract: PURPOSE:To obtain stable opening degree detection accuracy over the entire opening degree range by correcting a learnt correcting value so that the value obtained by correcting a 2nd valve opening degree detected value with the learnt correcting value approximates to a 1st valve opening degree detected value. CONSTITUTION:A valve opening degree detected by a 1st valve opening degree detecting means is selected by a valve opening degree detected value selecting means in a range where the throttle valve opening degree is small. A valve opening degree detected by a 2nd valve opening degree detecting means is corrected with the learnt correcting value stored in a storage means in a range where the throttle valve opening degree is large and the obtained value is selected by the selecting means. In a range where the valve opening degree is detected by both 1st and 2nd valve opening degree detecting means, on the other hand, a learnt correcting value correcting means compares the value obtained by correcting the 2nd valve opening detected value with the 1st valve opening detected value and corrects the learnt correcting value so as to approximate the former to the latter, thereby rewriting the learnt correcting value stored in a learnt correcting value storage means with the corrected correcting value. Thus, a step in detected value caused by the switching of the valve opening degree detecting means is eliminated.

Title: Projective color picture receiver
Inventor: OGAWA YOUJI
IPC: H04N9/31
Filed: 1983-05-10
Abstract: PURPOSE:To obtain a projective color picture receiver with brightness and high resolution by arranging an electromagnetic focusing means of a blue color projecting tube nearer the fluorescent screen than other tubes and increasing the beam spot diameter of the blue color projecting tube only at a large current so as to relax the saturation of luminance. CONSTITUTION:In projecting a monochroic picture pictured on the fluorescent screen of three projecting tubes 20R, 20G and 20B lighted in red, green and blue colors onto a picture screen 23 by using projecting lenses 22R, 22G and 22B, a focusing coil 21B of the blue color projecting tube 22B causing the saturation of luminance at a smaller current than that of the other two tubes is placed nearer the fluorescent screen than focusing coils 21R, 21G for the other colors. Although the beam spot diameter is more decreased in a small beam current as the focusing coil is neare the fluorescent screen, the beam spot diameter at a large beam current is increased when the coil is too near or too far from the screen as shown in Curve II. Thus, the beam spot diameter of blue color is increased at a large current thereby suppressing the saturation of luminance by placing the blue focusing coil to a point B and the others to a point A in this way.
