Title: Gate driving circuit for power converter
Inventor: TAKIZAWA AKITAKE
IPC: H02M1/08
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To form a gate driving circuit of a voltage driven switching device at a low cost. SOLUTION: This gate driving circuit includes a serial circuit of a diode 1 and a capacitor 2 connected in parallel between the emitter and collector of an IGBT3, for example, as a switching device. If comparator detects that the voltage of the capacitor 2 is beyond its prescribed value while the IGBT3 is being turned off, an output is generated from a delay circuit 7 after a fixed time passes to change a gate condition, for example, to increase a gate resistance value. It is thus possible to attain simplification of the circuit as well as elimination of a snubber circuit and low noise.

Title: Method for evaluating toxicity of activated sludge
Inventor: MASUI TAKAAKI
IPC: C02F3/12
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To easily and highly precisely measure the toxicity of various kinds of wastewater to sludge without being affected with the substrates in the object water to be tested by measuring the maximum aspiration speed to the same standard substrate before and after contact with a poisonous substance and evaluating the toxicity by comparison with the obtained data. SOLUTION: One litre of activated sludge in a sewage treatment site is sampled and aerated until the aspiration speed reaches self-decomposing speed. The resultant activated sludge is put in a first sealed tank of an aspiration speed measuring apparatus and while the aspiration speed being measured, primary to tertiary treatment is carried out. NH4 Cl is added in the primary and tertiary treatment and a mixed solution containing glucose and copper sulfate is added as an object water to be tested. Nitrification inhibiting ratio (%) can be calculated as following based on the fluctuation of aspiration speed at that time with the lapse of time: Nitrification inhibition ratio (%)= (B-A)/B}×100=25% wherein A=53(mg/L/h), B=40(mg/L/h). In this manner, the toxicity to activated sludge can be easily and highly precisely measured.

Title: Production of high-quality diamond
Inventor: YASHIRO YUJI
IPC: C30B29/04
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To suppress lattice defect and produce a good-quality diamond having little H content. SOLUTION: A diamond is formed into a film on a carbonized Si substrate 1 by a microwave plasma CVD method. In this case, diamond growing surface is irradiated with infrared light 2 having the same frequency as that of C-H stretching vibration of C-H bond on diamond 3. As a result, lattice vibration occurs only by C-H bond and lattice vibration of C-H bond is activated by resonance between light vibration and lattice vibration and finally, the lattice vibration is excited until the potential energy between C-H becomes maximum value to dissociate H. Thereby, H causing lattice defect is eliminated to form good-quality diamond having slight H content.

Filed: 1988-12-12
Abstract: PURPOSE:To improve surface appearance, and to obtain excellent electromagnetic-wave trouble preventive characteristics by containing a specific quantity of a methyl methacrylate-butadiene-styrene copolymer resin in a styrene group resin. CONSTITUTION:A 5-50wt.% MBS resin (a methyl methacrylate-butadiene-styrene copolymer resin) is included in all styrene group resin comprising the MBS resin in addition to the styrene group resin. That is, when the MBS resin is compounded into such a styrene group resin composition at a fixed rate, a phenomenon in which styrene fibers are exposed to the surface of a molded form, and the appearance of the molded form is improved remarkably. The loading of the MBS resin in all styrene group resin must be kept within a range of 5-50wt.%, and it is desirable that the loading is kept within a range of 10-30wt.% particularly. The effect of the improvement of appearance is not displayed sufficiently when the loading of the MBS resin is made smaller than 5wt.%, and the viscosity of the resin composition is increased and moldability is inhibited when the loading exceeds 50wt.%. The molded form using such a conductive resin composition is employed, thus acquiring an electromagnetic shielding housing having excellent appearance.
