Title: Detecting unit of welding defect
Inventor: TANAKA SADAO
IPC: G01N27/92
Filed: 1979-06-08
Abstract: PURPOSE: To detect existence and the quantity of defects of slag winding-in in a welding part, by detecting the re-striking voltage of arc from the arc voltage of the AC submerged arc welding and by analyzing the detection result.  
     CONSTITUTION: Electrodes 1 and 2 of an AC submerged arc welding machine are moved in the arrow direction in one body on positioned work W while supported and guided by guide roller 3, and an AC arc is generated between electrodes 1 and 2 and work W to perform welding. The arc voltage is led to the primary winding of potential transformer 4, and the secondary winding of transformer 4 is connected to oscilloscope 5 for arc voltage waveform monitor and peak hold circuit 6. Operation processing unit 7 fetches a value corresponding to the re-striking voltage of arc and performs the operation processing of this data and displays the average of the re-striking voltage of arc for every fixed time and for every one welding process on display unit 8.

Title: Atmosphere gas generating device
Inventor: NARUSE TADASHI
IPC: B01J7/00
Filed: 1981-05-13
Abstract: PURPOSE: To eliminate facilities for preheating desulfurizing catalyst and reduce construction cost and operation cost by introducing high temperature atmosphere gas from a combustion furnace directly into a desulfurizer by-passing the cooler.  
     CONSTITUTION: In an atmosphere gas generating device, a valve 26 is closed and valves 27, 29 are opened when starting operation and while high temperature gas from a combustion furnace 1 is led to the space 21, gas passage 20 and space 22 of the first desulfurizer 6 through a conduit 25 a layer 16 of catalyst is heated.

Title: Inverter unit
Inventor: OKAYAMA HIDEO
IPC: H02M1/06
Filed: 1991-04-05
Abstract: PURPOSE:To suppress overvoltage and the like by connecting reactors connected between a DC bus and an arm, and a series circuit of absorving capacitors, a snubber diode and a snubber capacitor, in parallel with the arm. CONSTITUTION:Upon turn OFF of a GTO 1A, load current I is interrupted and a current flows through an absorbing capacitor (AC) 21A, a snubber capacitor(SC) 6 and an output terminal P. At that time point, current produced by the energy of a reactor (LA) 2A flows through AC 21A, 21B, LA 2B. Furthermore, a free wheel diode(FD) 10B is conducted. When the energy of the LA 2A is absorbed by the AC 21A, 21B, the AC 21A, 21B are overcharged thus completing commutation of the load current I from the GTO 1A to the FD 10B. Subsequently, overcharged energy of the AC 21A, 21B is collected to the RC 23 through a path of the LA 2B, AC 21B, a collecting capacitor(RC) 23, AC 21A, LA 2A. An energy regenerative circuit 24 then takes out energy from the RC 23 and regenerates to a DC power supply 11.

Title: Time base corrector
Inventor: MATSUDA NORIHIKO
IPC: H04N5/956
Filed: 1990-03-22
Abstract: PURPOSE:To enable an accurate signal processing even when another digital signal processing system is inserted before a D/A converter by detecting time base fluctuation from a signal sampled with a clock at constant time intervals and correcting this time base fluctuation on the same clock by using an interpolating means. CONSTITUTION:An input signal is sampled at the constant time intervals and converted to a digital signal by an A/D converter 2 and this obtained digital signal is temporarily stored in a memory 3. On the other hand, the time base error of the digital signal obtained by the A/D converter 2 is detected and outputted as time base error information and based on this time base error information, a signal amplitude is interpolated from the output digital signal of the memory 3 so as to form the digital signal equipped with a reference time base. This output signal is converted to an analog signal at the constant time intervals by the D/A converter 10. Thus, the accurate signal without the time base fluctuation can be obtained in the constant sampling cycle.

Title: Filter body
Inventor: YANAGISAWA MITSUO
IPC: B01D29/07
Filed: 1985-04-09
Abstract: PURPOSE:To perform filtration with a single filter body inexpensively, simply and continuously for a long time by winding filter cloth in multiple layers on the external periphery of an internal cylinder and cutting off and discarding the outermost filter cloth successively when the outer most filter cloth is clogged. CONSTITUTION:Filthy water fed from a water feeding port 5 passes from the external part of a filter body 10 toward an internal cylinder 11 through filter cloth 13 and inside filter cloth 12, passes further through filtrate holes 11a perforated on the inside cylinder 11 and reaches the inside of the inside cylinder 11. Purified filtrate is discharged from a water discharging port 6. When filtration efficiency reduces or continuous filtration becomes difficult by the accumulation of dust on the outside of the outermost filter cloth 13a, approximately one turn portion of the outermost filter cloth 13a is separated and discarded, and the filtration is continued again using the unclogged inside filter cloth 13b as the succeeding outermost layer. Thus, the successive outermost filter cloth 13 is discarded successively as it is clogged, and filtration is continued further.

Abstract: PURPOSE: To provide a method of bonding of a flexible film, wherein the flexible film such as a filter is caused to become convex and is bonded from the center thereof onto a bonding layer, so that inclusion of bubbles into the bonding layer is prevented when a color filter is mounted.  
     CONSTITUTION: First, a filter 13 is sticked to an forward end of a through slit 15 by evacuating the through slit 15, and is tentatively attached to an image sensor 12 with an bonding agent 11 applied thereon. Then the hollow cylinder 14 is moved so that the film is located immediately before the bonding agent, the pressure of an inside 17 is caused to become greater than the outside, and after the filter is caused to become convex, it is touched slightly with the bonding agent 11. In this stage, the image sensor 12 and the filter 13 are aligned, and as the pressure within the hollow cylinder 14 is reduced it is lowered. Thus, the filter 13 will touch the bonding agent at 16 of the center thereof at first and then the touched portion will be radially extended not to include any bubble therebetween. Thereafter the filter can be removed from the hollow cylinder.
