Title: Method for controlling consumable electrode ac arc welding machine
IPC: B23K9/073
Filed: 1992-03-17
Abstract: PURPOSE:To smoothly carry out arc starting and transfer to stationary welding by employing only reverse polarity at the time of generating an arc, increasing a ratio of straight polarity so as to attain a polarity ratio at the stationary time in order and also, increasing the wire feed speed to a target value according to the polarity ratio changing with lapse of time. CONSTITUTION:When a welding starting signal TS is inputted to an arithmetic and control part 13, the arithmetic and control part 13 commands the output of the no-load voltage at the EN ratio 0% and simultaneously, commands feed starting of a wire 9 toward base metals 11 at the slowdown wire feed speed for starting regardless of setting on a welding current setting device 18 to a motor driving circuit 14. When the wire 9 comes into contact with the base metals 11 and a welding current flows, a welding current detection part 17 detects it and the arithmetic and control part 13 changes over the wire feed rate to the proper one at the time of EN ratio 0%. After this, the EN ratio of the welding output is increased to attain the specified EN ratio. At this time, the proper wire feed rate is also controlled simultaneously with the change of the EN ratio of the welding output.

Title: Servo system of optical head
Inventor: MARUTA KEIJI
IPC: G02B7/28
Filed: 1983-04-07
Abstract: PURPOSE:To attain the tracking servo immune to the effect of a recorded bit by detecting a focus error and a skew error by means of a main spot and a side spot generated in radial direction so as to perform servo control. CONSTITUTION:A laser light from a laser light source of a detecting head P is processed by a diffraction grating 2, and the main spot for information and a couple of side spots in radial direction clipping a track are recorded separately in an excellent way at the recording onto a disc D. The side spots on the disc D are read separately from the main spot by a photodetector 9 provided with a beam splitter 6 and two sets of photoelectric elements so as to generate the skew error signal for tracking servo. On the other hand, the main spot is read by a lens 4, a beam splitter 3 and a photodetector 5 so as to generate a focus error for focusing servo. Through the constitution above, the servo track control with high accuracy is attained without being affected by the recorded bit.

The control section 1 drives a lateral feed motor 5 such that the print head 3 is moved with half of normal speed then drives a print head driver 2 and prints the dot image developed in an image buffer 8. Then the control section 1 drives a driver 6 such that a paper feed motor 7 feeds a paper by half of dot interval. When printing is carried out second time, the control section 1 takes out only even number of dots in vertical direction and performs print control same as in the first time.

Title: Air-fuel ratio control device of internal combustion engine
Inventor: MEGURO TAIICHI
IPC: F02D41/14
Filed: 1989-03-13
Abstract: PURPOSE:To precisely conduct air-fuel ratio correction related to purge of fuel vapor by providing an exhaust gas component sensor, air-fuel ratio feedback control signal generating means, fuel vapor purge quantity learning means, learning control correction value correcting means and fuel supply quantity correction means. CONSTITUTION:There are provided means 76 for correcting a learning value of purge quantity and correct a learning control correction value when the average value of an air-fuel ratio feedback control signal is shifted from the control central value in the equilibrium condition. By this arrangement, when the suction air flows through a by-pass intake passage 30, that is, at the time of idle-up, a correction value of learning control is decreased as compared with that at the time of non-idle up. Thus, at the time of idle-up, it is possible to avoid a learning value from shifting from the proper value largely even when the frequency of skip of an air-fuel ratio feedback control signal is abnor mally increased due to deterioration of a characteristic of distributing suction air between cylinders and the frequency of correcting a learning value is in creased, and it is avoided to make a wrong idle purge quantity learning control.

The resin 21 which is assembled in a block body housing pocket 32 in a centrifugal bucket 31 is set up to place the electrode 25 outside the bucket 31 and the conductor 26 upside. The pocket 32 is inclined about 15 deg. to easily escape air contained in the deepest position of the conductor hole 24 to the opening of the hole during centrifugal treatment, so that the resin 27 can be concentrated on an adjacent area at a minimum filling amount. After preset rotation, the resin 27 is given hardening treatment to lap the electrode plane for completing a sensor.
