Title: Device for regulating iron concentration in reactor feed water
Inventor: NAWAI TAKEO
IPC: G21D3/08
Filed: 1987-07-08
Abstract: PURPOSE:To regulate the concn. of the iron in reactor feed water, etc., to adequate values by sampling a part of the feed water, detecting the iron concn., detecting the nickel ion concn. in the reactor water, and controlling the supply rate of the reactor feed water and the iron-contg. liquid. CONSTITUTION:An iron concn. detector 11 continuously detects the initial iron concn. of the feed water which is branched to a sampling piping 5 by opening a valve 4 and is cooled by a cooler 7, etc., to the state of ordinary temp. and atmospheric pressure. On the other hand, the nickel ion concn. in the reactor water is detected by a nickel ion concn. detector 21. The detection signals by these detectors 11, 12 are converted to analog signals and are transmitted to an arithmetic controller 22. The nickel ion concn. in the reactor water is determined according to the prescribed equation in this controller. The controller 22 operates and controls a regulating valve 13 in accordance with the computed set value of the iron concn. to inject a proper volume of the iron-contg. liquid from a storage tank 12 into a regulating tank 10 and to introduce the feed water via a 3-way valve 9 into the tank 10. The iron concn. of the feed water flowing into the reactor 3 is thereby maintained at the adequate value.

Title: Arc controlling method for tig ac welding
Inventor: TANIOKA SHINICHI
IPC: B23K9/073
Filed: 1986-07-17
Abstract: PURPOSE:To change the depth of penetration, the width of a bead, etc., of base metals by an arc by adjusting plus and minus current components of an electrode. CONSTITUTION:When a bias current at the plus side is applied to an AC at the normal time, the plus current component of the electrode 2 is increased and the electrode 2 acts like a positive electrode with respect to the base metals 3. As a result, a state near the reversed polarity is formed and the arc 4 can perform the welding with the relatively shallow spreading penetration and the wide bead width and furthermore, a cleaning action is also improved. On the other hand, on the contrary, the bias current at the minus side is applied to the AC at the normal time and the minus current component of the electrode 2 is increased and the electrode 2 is allowed to act like a negative electrode with respect to the base metals 3 to form the state near the straight polarity. In this way, the arc 4 which is not so much spread out is generated and the welding with the relatively deep penetration and the narrow bead width can be performed.

Title: Manufacture of amorphous silicon image sensor
Inventor: SOEDA SHINICHI
IPC: H01L27/146
Filed: 1985-07-31
Abstract: PURPOSE:To simplify the manufacture of an insulator between upper and lower electrodes by forming the insulator by allowing an insulating film to remain on the side of an active layer, and forming an upper electrode connected with the active layer. CONSTITUTION:A lower electrode 2 made of indium oxide, ITO or tin oxide is formed on a glass substrate 1, and an active layer 3 is formed of an amorphous silicon film. Further, organic or inorganic insulator such as polyimide is coated to form an insulating film 41, and unidirectionally dry etched with oxygen plasma or other gas. At this time, the film 41 remains only on the side of the layer 3 due to the difference of the thickness of the film 41, and the remaining insulating film is an insulator 4 between the upper and lower electrodes. After NiCr, or Al is formed 1-2mum thick thereon, it is patterned by a lithographic method to form an upper electrode 5. Thus, the insulator between the upper and lower portions can be simply formed without using the lithographic method.
