Title: Automatic focusing device for microreader or the like
Inventor: SAKAMOTO KEIJIROU
IPC: G02B7/28
Filed: 1986-07-24
Abstract: PURPOSE:To decrease a fact that a focus detecting area conforms to a null part, and to exactly detect a detecting signal such as a focusing signal, etc., by providing a rectangular focus detecting area by inclining it obliquely in the horizontal direction or the vertical direction of a projected image area. CONSTITUTION:An image of a microfilm 2 is projected or a screen 8 through a lens 3, the first mirror 4, the second mirror 5 of a reader system, and the third mirror 6 of the reader system. On a screen equivalent surface P of the diagonally upper part of the screen 7, an automatic focusing element is provided, and by displacing the first mirror 4, the image of the microfilm 2 is projected to the screen equivalent surface P. The automatic focusing element 8 is placed obliquely against the horizontal direction or the vertical direction of the screen 7, and the automatic focusing element 8 itself prescribes a focus detecting area. Even when the focus detecting area obliquely situated, and the image of the microfilm 2 is a document of lateral writing or vertical writing, it scarcely occurs that the focus detecting area conforms to its null part.

Title: Laser welding method
Inventor: OMAE TAKASHI
IPC: B23K26/346
Filed: 1986-07-24
Abstract: PURPOSE:To weld thick plates at a high speed with an inexpensive medium output laser by performing the deep-penetration welding on the surface side of the plate and afterward, performing the MIG welding on its rear side. CONSTITUTION:A groove shape of objects 1 to be welded is worked in an inverted Y type and the surface side is made to a groove part 2 for the laser welding and the rear side is made to a groove part 3 for the MIG welding. Then, the surface side is subjected to the deep-penetration welding by the laser beam 14 and afterward, the rear side is subjected to the MIG welding by generating a MIG welding arc 10. Since a plasma-shaped product by the laser beam 14 is absorbed and eliminated by the arc 10, the laser welding can be performed at a high speed and since the product exists on the rear side, the MIG welding arc is stabilized thereon. As a result, the thick plates with thickness 15mm, for instance, can be welded at a high speed of 1m/min by a 3 KWCO2 laser beam machine.

Abstract: PURPOSE:To remove the abrasion or the breakage of the grind stone on the periphery of a blade, while the shock generated when the blade is brought in contact with a table by keeping the supporting force of a rotor shaft lower than cutting time, when the table is brought in contact with the table at the operation of set up. CONSTITUTION:When the command of set up is outputted from PC, spindle- controlling part sends such an indication that the exciting current outputted from a magnet driver 73 to a compensation-treating circuit 72 is dropped lower than cutting time, and the exciting current corresponding to said indication is fed to each electric magnets 62n, 64n, and then the supporting force of the rotor shaft 61 in a spindle 6 is reduced lower than cutting time. When the spindle 6 is lowered, the grind stone 5a on the outer periphery of the blade 5 fitted to the rotor shaft 61 of the spindle 6, is brought in contact with the upper surface of a chuck table 10, but since the supporting force of the rotor shaft 61 is reduced lower than normal cutting time, the shock generated when the blade 5 is brought in contact with the chuck table 10 may be made small, whereby the abrasion or the breakage of the grind stone 5a on the outer periphery of the blade 5 may be removed.

IPC: F02D41/34
Filed: 1983-09-22
Abstract: PURPOSE:To keep off the failure of fuel in time of operation at high output or the like as well as to avoid any output drop, by increasing a fuel injection quantity from a slow fuel injection valve in the case where a nozzle part of a main fuel injection valve causes its loading. CONSTITUTION:In time of idling, when loading happens in a nozzle part of a main fuel injection valve 14 with operation suspended and thereby a fuel injection quantity becomes dropped by degrees, a theoretical air-fuel ratio is longer keepable at an operation range where an air-fuel mixture is feedback-controlled into the theoretical air-fuel ratio. Therefore, in order to detect the said loading, an output signal out of an O2 sensor 31 is inputted into a proportional integration circuit 32, and when the mean output exceeds the specified value deviated to the lean side, a lean signal is made to be outputted out of a discrimination circuit 36. And, when the lean signal is continued longer than the specified time to be set at a timing circuit 37 and outputted, it is judged that loading happens whereby the fuel that is made to increment from a slow fuel injection valve 16 via a compensating operation circuit 33 is sprayed.
