Title: Microwave plasma treatment device
Inventor: FUJIMURA SHUZO
IPC: H01L21/3065
Filed: 1986-09-13
Abstract: PURPOSE:To make uniform and improve a treatment speed by making an energy distribution uniform, thereby arranging a metallic phase shifter for diffusing microwaves inside of a waveguide. CONSTITUTION:A phase shifter 18 is composed of, for example, a metallic piece 18a of aluminum and the like as well as a support 18b made of teflon as a heat resisting insulator, while it is necessary for the metallic piece 18a not to be earthed but to be electrically floated, because it is liable to absorb microwaves, once it comes in contact with a waveguide and so on. Therefore, the support 18b is composed of an electric insulator. As to effects of this metallic piece 18a, it is deemed to be as follows: it is not always clear from the theoretical point of view for this metallic piece to be considered that is serves as a kind of antenna and also the microwaves are so reflected and diffused by the metallic piece that an uniform energy distribution can be obtained by this metallic piece. However, plasmas can be uniformly developed by a convolutional effect between a microwave that directly passes through a transmission aperture 13 and other microwave that is reflected from the metallic piece and transmitted.

Inventor: NISHIMURA SHINGO
IPC: B23K9/127
Filed: 1991-08-27
Abstract: PURPOSE:To provide the automatic welding device and its welding condition control method which can execute stable welding by keeping a heat input to an object to be welded constant, in the case of executing TIG welding by an automatic welding machine and a welding robot having functions for follow-up of a weld line and height control between the object to be welded and a torch. CONSTITUTION:A sensor 15 provided integrally with a torch 13 detects follow-up of a weld line and height of the torch 13, therefore, while keeping arc length h constant, welding can be performed. In such a state, a heat input control part 9 measures a welding voltage E, compares a heat input Qb calculated from its value and a proper heat input Q a, and executes control so that in the case the heat input Qb is larger than the proper heat input Qa, a welding current, I is lowered, and in the case the heat input Qb is smaller than the proper heat input Qa, the welding current I is raised. Therefore, even if a welding condition of an object W to be welded is varied, the heat input Qb to this object W to be welded always becomes roughly constant, and stable welding can be performed.

Abstract: PURPOSE:To attain stable detection without being influenced by the dispersion of light source emission distribution by arranging an optical member having a spherical aberration in an optical path between a light source and a beam splitter and detecting a change in the distribution of illuminance based upon the optical member. CONSTITUTION:Light from an LED 1 is projected to an optical card 6 through a sapphire ball 2 having a spherical aberration and about 1.8 refractive index, a collimeter lens 3, a beam splitter 4, and an objective lens 5. The reflected light is detected by a photodetector 8 through the lens 5, the beam splitter 4 and an image forming lens 7. Since the sapphire ball 2 is stuck and fixed to the light emitting part 1a of the LED 1 and the LED 1 is emitted, a ring-like bright part 2a is formed on the sphere of the sapphire ball 2 by its spherical aberration without almost being influenced by the dispersion in the light emitting distribution of the LED 1. Thus, a focus state can be detected without almost being influenced by the dispersion of the light emitting distribution of the LED by detecting a change in the illuminance distribution on an optical card based upon the spherical aberration.
