Title: Bod sensor and measuring method of bod
Inventor: TAKADA SUSUMU
IPC: G01N27/327
Filed: 1992-04-07
Abstract: PURPOSE:To enable measurement of BOD (biochemical oxygen demand) by using an activated sludge in which magnetic powder is taken in beforehand and by forming a microbe film by a magnetic force on the surface of an electrode for a BOD sensor which uses a conductive magnet at least for the surface of a cathode. CONSTITUTION:A cathode 4 is prepared by plating the surface of an Sm-Co magnet, for instance, with platinum. The lower side and the periphery of the cathode 4 are surrounded by an oxygen-permeable diaphragm 10 and the upper part of the diaphragm is fixed around a vessel 1 by an 0 ring 11. In this condition, magnetic powder is mixed with an activated sludge collected at a place of measurement. The cathode 4 is made to attract this mixture through the diaphragm 10 by a magnetic force and thereby a microbe film 12 of the magnetized activated sludge is formed. A BOD sensor thus prepared being used, it is brought into contact with a sample liquid to be measured. Then the microbe film 12 digests an organism in the sample liquid and consumes oxygen in accordance with BOD concentration and, therefore, the oxygen reaching the diaphragm 10 lessens. On the occasion, a difference in an electromotive force corresponding to dissolved oxygen occurs between the cathode 4 and an anode 6, a current is generated and it is measured by an ammeter 8.

That is to say, a prescribed distance obtained by multiplying the access distance from the starting point of the movement of the actuator by a prescribed constant with a movement residual distance, when the residual distance is longer than the prescribed distance, a fixed speed corresponding to the distance to the target point when a movement is made at the prescribed distance is used as the reference speed and when the residual distance is shorter than the prescribed distance, a fixed speed corresponding to the movement residual distance is used as the reference speed. Thus, the overshoot can be prevented.

Title: Manufacture of semiconductor nonvolatile memory
Inventor: OSHIKAWA YOSHIHIRO
IPC: H01L21/8246
Filed: 1982-06-29
Abstract: PURPOSE:To enable to operate the write and erase of an EEPROM with a low voltage and improve integration degree by thickening the film thickness of a semi-insulation film by a method wherein a polycrystalline Si film is adhered on an Si substrate, a crystal grain diameter is grown into a larger grain diameter, and next the polycrystalline Si is changed into an SiO2 film by high temperature treatment. CONSTITUTION:The polycrystalline Si film 11 of the film thickness of 50-200 deg.C is adhered on an Si substrate 10 by a reduced pressure chemical vapor growing method. Next, it is heated in the flow of the mixed gas of oxygen and argon, and then formed into the SiO2 film 12 of the film thickness approximately twice by oxidation. The polycrystalline Si film requires complete oxidation to the inside, and thereat oxygen is infiltrated from the crystal grain boundary to the surface of the Si substrate, which is accordingly oxidized. Thereby, unnevennesses proportional to the size of crystal grains are formed between the Si substrate and the SiO2 film. When an electric field is impressed by forming an insulation film composed of an SiO2 film having unevenness between the substrate surface, field concentration generates on projections, and then electrons can be injected with a low voltage. Since the SiO2 film can be formed thick as a whole, the capacity Ct thereof can be reduced.
