Title: Treatment of excavation sludge water
Inventor: KUNIHARA HIROSHI
IPC: C02F9/00
Filed: 1980-05-09
Abstract: PURPOSE:To treat excavation sludge with good efficiency by flocculating the excavation sludge water and separating the same to flocculated water and sludge then subjecting the treated water thereof or the separated water from the sludge to oxidation treatment with hydrogen peroxide in the presence of iron ions. CONSTITUTION:After flocculant is added to excavation sludge water from a cast- in-place pile work or the like to allow flocs to form, it is subjected to filtration dehydration by a filter press or the like, whereby it is separated to the flocculated water and sludge. Thence, an acid such as sulfuric acid is added to the flocculated water and/or separated water from the sludge to control pH at 1-4, and iron salts are added to this and oxidation treatment is performed by introducing hydrogen peroxide. Further, it is equally well to perform oxidation treatment by adding peroxide such as ammonium persulfate. Iron ions may be either ferrous ions or ferric ions; usually, they are added in the form of ferrous ions such as ferrous sulfate.

IPC: H04L27/36
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To attain phase modulation at an arbitrary angle. SOLUTION: A selecting circuit 6 alternately selects an I signal and a Q signal obtained from an input carrier wave in each semicycle(1/fs) of a first switching signal. A selecting circuit 5 outputs a signal whose phase is different only by 1/fs from the output signal of the selecting circuit 6. A CPU 10 generates coefficients C1 and C2 according to the phase variation of input phase change data. The coefficient C2 is generated so as to be alternately inverted in each 1/fs, the coefficient C1 is supplied to a multiplier 7, and the coefficient C2 is supplied to a multiplier 8. The output signals of the multipliers 7 and 8 are added and synthesized by an adder 11, and a signal processed by a matrix operation for phase change is extracted. Afterwards, an analog phase modulated signal is obtained by a Pythagoras converter 15, LUT 16, multiplier 17, and D/A converter 18.

Title: Manufacture of semiconductor device
Inventor: NAKAYAMA RYOZO
IPC: H01L21/76
Filed: 1985-03-26
Abstract: PURPOSE:To separate elements while avoiding creation of cross bird's beaks and crystal defects of a semiconductor substrate by a method wherein a groove for the element separation is formed and a semiconductor film is formed in the groove only with its surface level below the surface level of the substrate and a flattening film and an insulation film formed over the groove are etched overall. CONSTITUTION:An Si substrate 11 is selectively etched using an SiN film 13 as a mask to form a groove 14 in a field region. A polycrystalline silicon film 16 is formed to fill the groove 14. The polycrystalline silicon film 16 is etched overall so as to be left in the groove 14 only. After a thick SiO2 film 17 is formed on the whole surface, a photoresist film 18 is formed by coating. Then the whole surface is etched by mixture gas to remove the SiN film 13 and then an SiO2 film 12 is removed. As the shoulder part of the SiO2 film 17 is formed round in this process, the surface is so formed as to have a gentle shape. As the LPCVD-SiO2 film 17 is formed on the Si film 16 in the groove 14 like this, there is no possibility of creation of bird's beaks at the time of the formation of the SiO2 film 17.

Title: Surface treatment and apparatus therefor
Inventor: OOSAKATANI TAKAYOSHI
IPC: G03F7/42
Filed: 1988-03-14
Abstract: PURPOSE:To shorten the time for a surface treatment of an object to be treated by a method wherein active oxygen obtained by irradiating ultraviolet rays onto nitrous oxide gas is supplied to the surface of the object to be treated and a prescribed surface treatment is executed in order to dissociate active oxygen O (<1>D) of high concentration. CONSTITUTION:A wafer 6 is placed on the surface of a wafer stage 5; the stage 5 is started to turn. When a valve 11 of a nitrous oxide gas supply source 2 is opened, nitrous oxide gas is introduced into a treatment chamber 1 through a pipe 3 and is diffused to the whole surface of the wafer 6 through a slight gap between the surface of the stage 5 and a glass sheet 8. An excitation reaction is caused by ultraviolet rays radiated from a lamp 9, and active oxygen 0 (<1>D) of high concentration is dissociated; accordingly, a resist which has been applied to the surface of the wafer 6 is oxidized and decomposed quickly to a volatile low molecule such as CO2, H2O, N2 or the like. By this setup, the time for a surface treatment of an object to be treated, i.e. the water 6, can be shortened.

IPC: B41J9/38
Filed: 1985-03-28
Abstract: PURPOSE:To reduce the magnetic resistance of a magnetic path and contrive a smaller size and higher response characteristic, by intermediately providing a magnetic fluid between a side face of an armature and a surface of a yoke opposed to the side surface. CONSTITUTION:Where a printing head is not printing, a lower surface of the armature 4 is attracted to a core of an electromagnet mechanism, and the gap between the side face of the armature 4 and an auxiliary yoke 2b is filled with a magnetic fluid 7, so that the magnetic resistance of the magnetic path is extremely low, and the armature 4 is attracted to the core more strongly as compared with the case where the magnetic fluid 7 is not intermediately provided. When a coil 9 of the electromagnet mechanism is momentarily energized, the magnetic flux phia present in the magnetic path is canceled, and the armature 4 is released from the core by elastic energy stored in a spring 6. An electric current required for generating a reversely exciting magnetic flux phib can be smaller as compared with that in the case where the magnetic flux 7 is not provided between the side face of the armature 4 and the auxiliary yoke 2b.

Filed: 1984-03-30
Abstract: PURPOSE:To enable a quick and accurate measurement of the content of organic acid continuously by mixing a diluting solvent and a sample liquid and flowing the mixture to a probe as diluted sample to measure the conductivity with a measurement processing circuit. CONSTITUTION:A diluting solvent and a sample liquid from a solvent tube port 1, a sample tube port 2 and an extrusion liquid tube port 3 are forced to a mixer 5 with a microtube pump 8 via a mixing point (MP)10 to be mixed uniformly as a diluted sample and flows to a flow-through type 4-electrode cell 6. When current is applied between a pair of electrodes in a measurement processing circuit 7 with a probe chamber through which the diluted sample in the electrode cell 6, the current flowing is proportional to the conductivity of the solution. So, the conductivity is collated with the calibration curve of the content of organic acid to measure the content of organic acid in the diluted sample. This enables the dilution of a sample liquid at a high rate thereby assuring an accurate measurement of the content of organic acid.
