Title: Production of high-purity ferric oxyhydrate
Inventor: KONDO HIDENOBU
IPC: C01G49/02
Filed: 1986-10-30
Abstract: PURPOSE:To obtain ferric oxyhydrate having high purity and lowered SiO2 content, by neutralizing an acidic waste liquid containing ferrous salt using a specific slaked quicklime as an alkali agent. CONSTITUTION:Ferric oxyhydrate is produced by neutralizing an acidic waste liquid containing ferrous salt with an alkali agent composed of a slaked quicklime produced by sieving quicklime using dry classification process, slaking the sieved quicklime having particle diameter of >=1mm and sieving the slaked lime to collect the fraction having particle diameter of <=0.5mm. The contamination of ferric oxyhydrate with SiO2 can be decreased by using quicklime as a raw material because quicklime has low SiO2 content compared with slaked lime. The SiO2 content of quicklime can be further decreased by removing particles having particle diameter of <=1mm and having especially high SiO2 content by dry classification process. Further, coarse gangue mineral having particle diameter of >=0.5mm and composed mainly of SiO2 is removed by sieving and then particles having particle diameter of <=0.5mm are collected to obtain slaked quicklime having remarkably decreased SiO2 content.

Title: Manufacture of semiconductor device
Inventor: SETA SHOJI
IPC: H01L21/302
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of rough etching which causes dust at a substrate outer edge by coating an insulating layer at the substrate outer edge as well as a semiconductor substrate with an organic compound silicon film which is decomposed into a film of high etching-resistance under energy projection. SOLUTION: A polysilane film exposed at a substrate outer edge is selectively irradiated with electron ray. Due to the electron ray projection, the irradiated part changes to a decomposition part 45 of a high etching-resistant material. Then, with the pattern of a resist film 50 as an etching mask, a laminated insulating film comprising a thermal oxidation film 15, a silicon nitride film 20, and a TEOS film 30 is etched. Since the decomposition part 45 which was decomposed under electron ray projection is a film of high etching-resistance, the film reduction during etching is less while the silicon nitride film 20 and the TEOS film 30 at the substrate outer edge are not etched.

Title: High-voltage power source circuit
Inventor: MAEBA YUKIO
IPC: G03G15/02
Filed: 1989-10-04
Abstract: PURPOSE:To allow the equiv. turning on and off of a high-voltage circuit while a voltage is held impressed at all times to an electrifier by providing a regulator circuit for controlling a grid voltage and a switch for this circuit. CONSTITUTION:The voltage is supplied from an output transformer 12 to a middle-voltage circuit 42 and the high-voltage circuit 10. The middle-voltage circuit 42 operates and the voltage is impressed to a discharge electrode 20 of the electrifier 18 connected to the output terminal of the high-voltage circuit 10. The grid voltage is, thereupon, applied to the grid electrode 24 of the electrifier 18 and the electrifier 18 starts corona discharge between the discharge electrode 20 and the grid electrode 24 and between the grid electrode 24 and the drum 28 when the regulator circuit 26 is turned on by the switch 38. The grid voltage of the grid electrode 24 drops and the corona discharge of the electrifier 18 arises only between the discharge electrode 20 and the grid electrode 24 when the regulator circuit is turned off by the switch 38 at the time of executing the corona discharge. The drum current does not, therefore, flow. The voltage circuit 10 turns off equivalently in this way.

Title: Displacement measuring instrument
Inventor: KOZUKI SUSUMU
IPC: G01D5/38
Filed: 1986-10-31
Abstract: PURPOSE:To measure displacement with high accuracy by extracting plural interference signals which are given a specific phase difference and correcting error signals that the interference signals contain when the interference signals are extracted by making diffracted light beams generated by a diffraction grating interfere with each other. CONSTITUTION:Luminous flux from a laser light source 1 is diffracted by a diffraction grating 2, reflected by corner cubes 31 and 32, and made incident on the grating 2 again. The positive and negative diffracted light beams which are diffracted again are made incident on a beam splitter 5 one over the other and divided into four by half-mirrors 51-54 to impinge on photodetecting elements 71-74 through polarizing plates 61-64. Here, the polarizing plates 61-64 are arranged having polarizing directions made different by 45 deg. respectively, so interference signals E1-E4 obtained from the photodetecting elements 71-74 have 90 deg. phase differences. Then their sum signals E13=E1+E3 and E24=E2+E4 are obtained by adders and corrected signals, the inversion of E13=E1/E13 and the inversion of E24=E2/E24 are obtained by dividers. Those corrected signals are inputted to a counting circuit to count light and shade parts of interference fringes, thereby finding the displacement of a body to be measured and its displacement direction.

Abstract: PURPOSE:To prevent occurrence of recess due to distortion of welding by integrally welding an angle framework member and an outer wall steel board at a bending corner section. CONSTITUTION:When each angle framework member 2 and an outer wall steel board 3 are welded together, electrodes are inserted sequentially into respective small holes 6 arranged at the bent corner section of the angle framework member 2, and then the electrodes are melted through arc welding or carbon dioxide gas welding.

Title: Abrasion state detector for magnetic head and magnetic recording and reproducing device
Inventor: MATSUZAWA HIROSHI
IPC: G11B5/455
Filed: 1989-10-05
Abstract: PURPOSE:To grasp the allowable limit by calculating different impedance between an occasional measurement value of impedance and an initial measurement value and detecting an abrasion state of a magnetic head. CONSTITUTION:Impedance of a rotary magnetic head 1 is measured initially and occasionally by impedance measuring means 4,...8, and the different impedance between the occasional measurement value and the initial measurement value stored in a storage means 9 is calculated by a computing means (computer) 8. In this case, the less a gap depth due to abrasion of the head the less the impedance, whereas the gap depth at the same impedance is different because of an impedance variation. However, a difference between the initial value of impedance and an allowable limit value of it is approximately proportional to a difference between an initial value of the gap depth and an allowable limit value of it. Consequently, the head abrasion state can be detected with the calculated different impedance. By this method, the allowable limit of the abrasion state can surely be obtained.

Abstract: PURPOSE: To provide an operation control method which can maintain denitrification reaction and nitration reaction satisfactorily in a two-stage active sludge circulation variation method. CONSTITUTION: A first aerobic tank 2a, anaerobic/aerobic doubling tanks 13a, 13b and a second aerobic tank 2b are connected in series to an anaerobic tank 1a, and nitration liquid circulation pumps 6a, 6b for feeding a nitration liquid to the anaerobic tank 1a are arranged from each aerobic tank 2a, 2b to the anaerobic tank 1a. Under this constitution, an ATU-rr meter is installed in the rear stage part of the first aerobic tank 2a.

In addition, the anaerobic/aerobic doubling tank 13a, 13b are caused to operate as the anaerobic tank or the aerobic tank, depending upon the completion or non-completion of the nitration reaction.  At the same time, the nitration liquid is returned to the anaerobic tank 1a through the first and the second nitration liquid circullation pump 6a, 6b to enhance the denitrification effect. Thus operation of the two-stage active sludge circulation variation method is controlled as described above.
