Abstract: PURPOSE:To detect positively the state of overload, and to control a power supply stably by controlling a driver circuit in the direction of the reduction of the value of currents fed to the driver circuit in response to an overcurrent detecting signal from an overcurrent discrimination circuit. CONSTITUTION:An overcurrent discrimination circuit 9 is composed of first and second monostable circuits 10, 11 and an input AND circuit 12, and a current detecting signal is input to the first monostable circuit 10 while being input to one input terminal of the AND circuit 12. The first monostable circuit 10 outputs a high level signal for a fixed time from an output terminal Q while outputting a low level signal for a fixed time from the output terminal Q, and supplies the second monostable circuit 11 with a signal from the output terminal Q. The second monostable circuit 11 outputs a high level signal for a fixed time from an output terminal Q, and feeds the other input terminal of the AND circuit 12 with a signal from the output terminal Q. The AND circuit 12 outputs an overcurrent detecting signal when signals input to each input terminal are all at high levels. A control circuit 13 controlling a driver circuit 3 is supplied with the overcurrent detecting signal.

Title: Selecting method for welding condition
Inventor: YAGI TAKAHARU
IPC: B23K9/095
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To select a proper welding condition by which the generation quantity of spatters is little from a welding current and the waveform of an arc voltage by paying our attention to a droplet transfer form. SOLUTION: The stability factor n/N of a droplet transfer is found by recording a welding current 4 and an arc voltage 5 on a recorder 7, and by counting the number of times N of a short circuit generated in a unit time and the number of times (n) of an instantaneous short circuit from the waveform of the arc voltage 5. These operations are performed by plural numbers of times by changing the arc voltage at some points. By comparing the plural stability factors n/N of the droplet transfer one another, the arc voltage is selected so that the stability factor n/N of the droplet transfer falls into a range of 0.4 or below in a low current area showing a short circuit transfer and the stability factor n/N of the droplet transfer falls into a range of 0.4 or below and 0.7 or over in a high current area which is a globular transfer.  A proper welding condition by which the generation quantity of spatters is little when using a welding robot, can be easily selected.

Abstract: PURPOSE:To produce a porous glass having a thickness of several cm and containing pores having diameter of several tens Angstrom , by mixing a sol produced by the complete hydrolysis of a metal alkoxide with a gel produced by the partial hydrolysis, stirring the mixture and gelling, drying and calcining the mixture. CONSTITUTION:A metal alkoxide such as silicon ethoxide is added with a prescribed amount of hydrochloric acid and completely hydrolyzed e.g. by vigorous agitation. The obtained solution is converted to a sol 1. Separately, silicon ethoxide is added with a small amount of hydrochloric acid to effect partial hydrolysis and the obtained solution is converted to a sol 2. The sol 1 is mixed to the sol 2, stirred and the pH of the mixture is controlled e.g. by the addition of ammonia water. The obtained sol solution is charged in a vessel, closed and left standing to obtain a gel. The vessel is bored with holes accounting for several % - ten odd % of the surface area of the vessel and the content is dried e.g. for 10 days to obtain a dry gel. The dry gel is put into an electric furnace and calcined e.g. at 600-800 deg.C. A porous glass having a thickness of as thick as several cm and containing pores with several tens Angstrom  in diameter can be produced by this process.

Abstract: PURPOSE:To perform the bending of a various shaped metal sheet with a single apparatus by supporting a roll shaft of rotatable roll with plural universal joints to displace in the three dimentional directions. CONSTITUTION:The rolls 1a, 2a and 1b, 2b are displaced in the three dimentional directions by operating each universal joints 8a, 8b, 9a, 9b so as to coincide with an intended binding line (a) of the metal sheet, then the metal sheet 7 is transferred from a supplying line. Thus, the metal sheet 7 is bent while put between the rolls, 1a, 2a and 1b, 2b. Then, in the case of bending a different intended line of bending, the information is inputted in a control device. Each roll 1a, 2a, and 1b, 2b is displaced by said input in three dimentional directions corresponding to the information and a different bending line is formed on the metal sheet 7. Therefore, the complex bending lines are formed without disposing a number of rolls and the versatility is improved.

Abstract: PURPOSE:To accurately measure the distance of a body to be measured without contacting by detecting the body to be measured being at a specific distance from whether or not the photodetection pattern of a photodetection part and the pattern of reflected laser light overlap with each other. CONSTITUTION:Laser light from a laser light source 21 is projected on the body 18 to be measured and its reflected laser light is photodetected by a rough photodetection part 29 and a fine photodetection part 30.

When the reflected laser light image is right on the optical axis K2, it is considered that the measurement point of the body 18 to be measured is accurately at the focus position of a lens 25, so the state wherein the body 18 to be measured and a constant distance are at the specific distance is detected. The measured distance is the focal length of a lens 25, so the distance is freely set by selecting the lens 25.

Abstract: PURPOSE:To reduce the burden of a passenger through saving of a force required for operation during return and to improve cutting precision by a method wherein a temporary movement aside command means and a managing means for a signal during movement-aside are additionally provided, a value matching a gradient during automatic cutting before manual cutting is maintained. CONSTITUTION:During automatic cutting, cutting is carried out in a way that an actuator is controlled according to a deviation between a cutting depth target value set by a target value setting means based on data on a desired depth and the detecting value of a running distance detector and the detecting value of a cutting depth detector. When temporary movement-aside to manual cutting is commanded by a temporary movement-aside command means, a managing means for a signal during movement- aside suspends control by an automatic cutting control means and continues setting of a cutting depth target value. Switching to manual cutting is effected and at a point of time when a device is moved over an obstacle, the device is restored to an automatic cutting state, and automatic cutting is restarted by means of a final value before the starting of manual cutting being the initial value of a cutting depth target value during restarting.
