Abstract: PURPOSE:To improve cutting efficiency so better as well as to make a smooth cutting surface by means of standardization in cutting conditions attainable, by setting up each drive motor in feed and takeup reels for a cutting wire, while installing a tension setting mechanism fitted with a capstan and a tension holding device. CONSTITUTION:On the basis of rotation of a groove roller drive motor 8, each of drive motor 22 and 25, 10 and 11 for a capstan and feed and takeup reels is driven and at this time delivery and takeup parts 14 and 15 are set to poor tension but a tension setting mechanism 5 to strong tension respectively, whereby a wire 2 is moved in an A direction at high speed, and it is wound up accurately in a bobbin form on a takeup reel 4 by a traverse mechanism 100. And, a setting member supporting a cut work member W gradually goes up by a lifting device together with a setting block, while the work member W is forcibly pressed to a wire stretched in parallel with the tension setting mechanism 5 whereby a cutting fluid is fed out of a pipe 80 and cutting takes place. Here, reaction to the work member W is detected by a load detector, and there is always given the specified pressing force in relation to the up position of the member W detected by a up position detector, thus finishing on a cutting surface becomes favorable enough.

Title: Excimer laser generating device
Inventor: WATABE SHIYUNTAROU
IPC: H01G4/35
Filed: 1983-11-24
Abstract: PURPOSE:To enable to impress a high voltage of quick rise and rectangular wave pulses of large current for a relatively long time by providing a pulse generating circuit equipped with a cylindrical dielectric ceramic wherein electrodes are adhered and formed on the inner and outer peripheries respectively. CONSTITUTION:The pulse shaping circuit PFL has a structure wherein an inner peripheral electrode 2 and an outer peripheral electrode 3 are formed on the inner and outer peripheral surfaces of the cylindrical ceramic 1 respectively. This PFL is operated with the clearance between the electrode 2 and 3 at one end (a) in the axial direction as the pulse input end and that at the other end (b) as the pulse output end. After charging a capacitor C by supplying a high voltage through an input resistor R, a sparking gap SG1 is closed, thus charging the PFL. When the charged voltage of the PFL becomes at a fixed value, resulting in the closure of a rail gap SG2, the rectangular wave pulses are impressed on a rare gas-halide excimer laser tube A, and accordingly the excimer laser at an ultraviolet ray region generates. Thereby, the excitation of said laser can be securely performed, and the miniaturization is facilitated.

CONSTITUTION: When initial explosion is effected through cranking with the aid of a starter motor, the number of revolutions of an engine is momentarily increased and thereafter converged toward the given target number of idle revolutions. Further, an intake negative pressure develops along with the increase of the number of revolutions of an engine after the starting of initial explosion and as a result, an air-fuel ratio is brought into a rich state and a misfire may sometime occurs. In which case, during a period set in such a manner to contain a period where a misfire is apt to occur, namely period wherein a lapse time starting from a change time from ON to OFF of a start switch is a given range, an exhaust gas recirculation control valve 3 is fully opened by a means 6 to control recirculation of exhaust gas after starting to execute the recirculation of exhaust gas.  Thereby, even when quantities of unburnt HC is discharged to a exhaust passage from an internal combustion owing to a misfire, most of the unburnt HC effects recirculate to an intake passage through an exhaust gas recirculation passage 2, and is caused to to effect combustion disposal in the combustion chamber.
