Title: Electron gun for cathode-ray tube
Inventor: TAKENAKA SHIGEO
IPC: H01J29/48
Filed: 1977-12-27
Abstract: PURPOSE: To improve the focus quality of a color picture receiver, etc., by making the divergence angle of electron beam slightly smaller by the relatively low-potential second focusing electrode in the main lense system consisting of four focusing electodes.  
     CONSTITUTION: A triode part is formed by cathode 21, the first electrode 22 and the second electrode 23, and the main lense system is constituted by the first to the fourth focusing electrodes 24 to 27. The first and the third focusing electrodes 24 and 26 are held at the same relatively middle potential, and the second focusing electrode 25 has a very short electrode length and is held at a low potential, and the fourth focusing electrode 27 is held at the same potential as the fluorescent face. Second-order derivative 28" of potential distribution 28 on this axis has two positive maximum values and three negative maximum values. That is, a constitution where a uni-potential- type lense as an auxiliary lense is inserted between electrodes obtained by the first focus electrode  of the high-potential-type main lense system into two is obtained, and the divergence angle of electron beam at the view from the main lense system is made slightly smaller. As a result, the spherical aberration at the center of the screen is reduced, so that the astigmatism dependent upon electron gun assembling error can be reduced, and advantages such as the improvement of focus uniformity can be obtained.

Abstract: PURPOSE:To provide proper air-fuel ratio by calculating a basic fuel injection amount, comparing a change amount of intake pipe pressure with a preset upper limit value to determine the change amount and calculating a fuel injec tion correction amount based on the obtained correction pressure change amount added to or subtracted from the basic fuel injection amount. CONSTITUTION:Volumetric efficiency is calculated from outputs of an intake pipe pressure sensor 101 and a crank angle sensor 102, and a basic fuel injection amount is calculated in a basic fuel injection amount calculating means 104. On the other hand, an output of an intake pipe pressure change amount calculating means 105 is compared with a preset intake pipe pressure upper limit value in an upper limit value setting means 106, to determine a change amount with the upper limit value serving as the limit. A correction pressure change amount is obtained from this determined change amount and a pressure change amount correction coefficient based on an output of a throttle position sensor 108, and a fuel injection correction amount is calculated in a fuel correction amount calculating means 112 and added to or subtracted from the basic fuel injection amount. Thus by operation with proper air-fuel ratio, drivability is improved.

Title: Optical cable
Inventor: SUGAWARA YASUYUKI
IPC: G02B6/44
Filed: 1988-06-26
Abstract: PURPOSE:To make an optical fiber hard to come out of a groove and to improve the tension characteristics of a cable by specifying the conditions of the sectional shape of the groove at an inversion part. CONSTITUTION:The path of an optical fiber 10 is shorter when the path passes the bottom 18 of the groove 14 before and behind the inversion part and passes the bottom 18 at the inversion part 16 than when it passes the bottom 18 of the groove 14 before and behind the inversion part 16 and passes a position other than the bottom 18 at the inversion part 16. Therefore, the path FGH of the optical fiber 10 which passes the bottom 18 of the groove 14 and the path FJH passing an opening part 20 at the inversion part 16 are nearly superposed on over the other when a slot 12 is seen from just beside. A position J is above G at C of the inversion part 16, so the path FJH is longer than the GFH. Consequently, even if tension operates, the optical fiber 10 in the FGH at the bottom 18 of the groove 14 never moves toward a side wall 23 are the long path FJH and the optical fiber 10 does not comes out of the groove 14.
