Title: Dry etching device and its cleaning method
Inventor: SANGO TOSHIAKI
IPC: C23F4/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To stably detect the end point of etching without degrading a working rate even if the number of treating sheets increases and without creating the cause for particles with a dry etching device having a window for an optical type end point detector. SOLUTION: The window 6 for detecting the end point of the side wall of the treating chamber 1 of the dry etching device is formed to a projecting shape and means (14, 15) for forming plasma for cleaning separately from plasma for etching are disposed, by which the deposits 11 sticking to the window 6 are removed. Then, even if the number of the treating sheets increases, the degradation in the working rate as in the conventional wet cleaning does not arise and the cause for the particles like the conventional dry cleaning is not created.

Title: Tig welding method
Inventor: KONO TAKAYUKI
IPC: B23K9/23
Filed: 1988-01-25
Abstract: PURPOSE:To improve welding quality by using Cr-Fe-Mo-Ni alloy materials to be welded and performing TIG welding by the welding heat input in the specific range and further, setting thickness per layer of a welding build-up part to more than the specific thickness. CONSTITUTION:In the TIG welding method for Cr-Fe-Mo-Ni heat resistant alloy thick plates, the Cr-Fe-Mo-Ni alloy materials are used as the materials to be welded to perform welding. At this time, the heat gain of 15-4OKJ/cm is regulated as the welding heat gain and the thickness per layer of the weld metal build-up part is set to >=1mm. Since the welding heat gain at the time of performing TIG welding is regulated in the proper small range, the high- temperature cracking is prevented. In addition, since the heat gain is set at a comparatively high value and the quantity of build-up per layer is set to >=1mm thickness, the number of build-up layers is reduced. Accordingly, precipitation cracking by a thermal cycle is also prevented and after all, the weld zone quality is improved.

Filed: 1992-01-29
Abstract: PURPOSE:To prevent the rotational load torque of an upper fixing roller from increasing by providing plural rotatable supporting rollers engaged in the groove part of the fixing roller on the upside of the fixing roller provided with the groove part in a circumferential direction on the surface of its end. CONSTITUTION:The supporting rollers 3 and 4 are engaged in the groove part 2 formed along a peripheral surface near both ends of the cylindrical upper fixing roller 1. The rollers 3 and 4 are arranged to be brought into contact with the oblique upside of the roller 1 so as to position the roller 1 lest the roller 1 should escape to the upside. A lower fixing roller 6 is pressed to the roller 1 side by a spring, and the upper and lower rollers 1, 6 are rotated when driving force is transmitted from a driving system. The rollers 3 and 4 are also rotated with the rotation of the rollers 1 and 6, and slip occurs between the respective shafts 3a and 4a of the rollers 3 and 4. Therefore, the rollers 3 and 4 are free to rotate, and when the roller 1 is rotated, the rollers 3 and 14 are smoothly rotated and the rotational load torque of the roller 1 is prevented from becoming large.

Abstract: PURPOSE:To detect clearly and accurately an ore transporting condition by providing an enlarged part in which a baffle plate is arranged in a transporting pipe of prereduced ores, and measuring a dynamically balanced condition constituted by pressures operating on the baffle plate by a loadcell. CONSTITUTION:In order to supply prereduced granular ores 22 from a prereducing furnace through a transporting pipe 6 to a tuyere branch, a hopper-shaped enlarged part 21 is formed on the midway of said pipe 6. A movable baffle plate 23 is arranged in an ore 22 transporting passage of the ores 22 at the enlarged part 21 and the baffle plate 23 is connected directly with a load cell 25 through a connecting stick 24. A dynamically balanced condition constituted by a static pressure and a dynamic pressure of the prereduced ores 22 operating on the baffle plate 23 and the pressure of gas 27 flowing backward from the tuyere branch is measured by this load cell 25. Since the directly connecting stick 24 penetrates the enlarged portion 21 through a hole 28, gaseous nitrogen 26 is made to flow so as not to drop down the ores from the hole 28.

Abstract: PURPOSE: To produce an inexpensive dust collector having a good dust-collecting property, by parallelly arranging curtain-like filter elements to a support frame in a manner such that their fiber-fixed parts are located in zigzags to constitute a filter.  
     CONSTITUTION: A filter element is one formed into a curtain-like state by fixing the centers of fibers to a support piece 11E in nearly the same intervals with an adhesive, turning up the free ends of the fibers, and hanging down the free ends. A plurality of the filter elements are arranged in a manner such that their fiber 11B-fixed parts are located in zigzags by notched slits 11F formed in a support frame 11C. Thus, the fibers 11B are arranged inside the support frame 11C by engaging the both ends of the support pieces 11E with the slits 11F to constitute a filter 11. As a result, an air-permeating density inside the filter is homogenized, and a air permeation resistance is reduced. Moreover, the filter elements can be easily produced. Consequently, an inexpensive dust collector having a good dust-collecting property can be obtained.
