Title: Welding method
Inventor: MATSUURA TOSHIHIKO
IPC: B23K9/028
Filed: 1994-05-09
Abstract: PURPOSE:To perform improved welding while operation from the inside is reduced, in butt welding of a cylindrical member. CONSTITUTION:Root running is performed on each root face 12 of a groove part 13 from inside of box columns 10a, 10b, and a root pass bead 14 is formed there. At this time, glass cloth 16 is interposed in each groove part 13 as a backing member and is held down on each groove face 11 by a holding member 17. Thus, after forming the root pass bead 14 between each of the root faces 12, and removing the glass cloth 16 and the holding member 17 that are interposed in the beveled part 13, a weld bead is laminated along each groove face 11 of the groove part 13 from outside of the box columns 10a, 10b.

Title: Elastic shaft joint
Inventor: MORIYAMA SEIICHI
IPC: B62D1/20
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To enable an inexpensive production with a simple structure by providing a first bracket having a pair of inner surfaces; a second bracket having a pair of outer surfaces; a butting member being loosely fitted at its intermediate part in an engaging hole of one of bracket, while being supported by the other bracket, and having an elastic member between its sides. SOLUTION: When axial oscillation is applied to a shaft 11, brackets 2, 3 displace axially while applying tensile load to an elastic member 8 between a pair of inner surfaces 5 and a pair of outer surfaces 7 to thereby prevent the oscillation from being transmitted to a shaft 12. When a rotational oscillation is applied to the shaft 11, the brackets 2, 3 displaces in the rotating direction to thereby prevent the oscillation from being transmitted to the shaft 12. At the time of absorbing each oscillation, the rod 10 displaces inside an engaging hole 9. During the time when torque is small, rotating force is transmitted while compression load is applied to the elastic member 8, and when the torque becomes large, the rod 10 is in contact with the widthwise inner edge side of the engaging hole 9 to thereby transmitting the rotation force. In this way a simple structure is attained.

Title: Monitoring device for welding condition and time change
Inventor: SUZUKI NORIYUKI
IPC: B23K11/25
Filed: 1989-04-17
Abstract: PURPOSE:To decide normality or defectiveness on every state of welding conditions changing momentarily by measuring momentary welding conditions by a welding state monitoring device of a welding machine and comparing a measured value thereof with a reference value to send out an alarm signal when the difference between both exceeds an allowable value. CONSTITUTION:The average value data (the reference value) of the welding conditions (the current, voltage and resistance) for each time when welding is performed under the same conditions in the past are stored in a storage part 5 via a control circuit 3 and in the same way, an allowance determined by conditions of welding materials is stored therein. A welding condition detection signal detected by a toroidal coil (not shown in the figure) in actual welding is supplied to the control circuit 3 via a waveform shaping circuit 1 and an A/D converter circuit 2 and warning is given by a buzzer or a display device when the difference between the measured value and the reference value exceeds the allowance. By this method, proper monitoring with respect to all cycles can be carried out.

Abstract: PURPOSE:To enable the tracking of a moving object, by providing a light- emitting element on the moving object while a light-receiving element is provided on a tracking robot to decide on the direction thereof based on the detection output of the light-receiving element. CONSTITUTION:Light from an infrared-ray emitting diode within a light emission source 2 so arranged on a moving object 1 non-directional is received with a plurality of light receiving elements 5 provided on a tracking robot 3. The element 5 which is a sensor comprising a photodiode is connected to sensor processors separately in a controller 6 and the direction of the light emission source 2 is determined by the sensor processor. Then, based on the decision data thereof, right and left wheels 4 are rotated separately by a necessary value. Thus, as long as the distance between the moving body 1 and the tracking robot 3 is within a fixed range, the tracking of the moving object 1 can be done without being restricted by the position of the moving object 1 and the position of the tracking robot 3.

Title: Proportional combustion process
Inventor: MATSUMOTO MICHIAKI
IPC: F23N5/12
Filed: 1983-06-01
Abstract: PURPOSE:To make a superior combustion during a start-up period by a method wherein a desired correction value and non-correction value are supplied after start-up of the ignition operation, the correction required value is varied from an area in which the sensing of the ignition may not be made by a flame sensing means to an area in which the ignition may be sensed under the fixed non-corrected element amount to perform the combustion. CONSTITUTION:An ignition is detected by applying a flame sensing circuit 60 after a voltage Vxo is outputted and the first desired time is elapsed. Since the ignition may not be detected in general with this volume of fuel, the desired voltage is added and a new voltage Vxn is outputted. With this condition, the volume of fuel is increased, and an air ratio N becomes low. When the ignition is detected at the time t1 within a safe time, a desired voltage DELTAV is added to the voltage Vx1 at that time to produce Vx2, and makes a superior air ratio N2 in combustion. A flame current value is I2. The new voltage Vx2 is kept until the time t2 when the second desired time is elapsed. The second desired time is defined at 5sec of a half of 10sec of the start-up period of the oxygen sensor 28. Within the second desired time, if the flame is extinguished, the system performs the non-ignition operation and when the hot water temperature is reached to the set temperature, it performs the combustion termination operation.

Title: Minimum detector of fluctuations
Inventor: AOKI SHIGEO
IPC: H03H3/00
Filed: 1978-08-04
Abstract: PURPOSE: To make it possible to effect the automatic control having the minimum fluctuation by accomplishing the control in a manner to have the minimum concecutive fluctuations so that the minimum fluctuation may be detected.  
     CONSTITUTION: For example, the frequency of a crystal oscillator, which has its frequency adjusted by a cutting process, is compared through an A/D converter 106 and a register 109 with the standard one of a memory 109 by a comparator 111 so that the fluctuation is stored in a register 112. The cutting process is so controlled through a control circuit 113 that the fluctuation may take a small value. The consecutive fluctuations from the register 112 are compared by a register 114 and a comparator circuit 115 so that this circuit generates the high level output as the minimum fluctuation detecting signal upon the inversion of the fluctuation difference. On the other hand, if the fluctuations of the register 112 are consecutively reduced, the minimum one is stored in a register 123 through an ABD gate 124 which is to be opened through a comparator 122. During the period while the fluctuations are slightly larger than the minimum, an AND gate 133 is opened so that the cutting process can be automatically stopped in response to the high level output of the comparator 115 having passed through the gate 113.
