Filed: 1993-04-05
Abstract: PURPOSE:To prevent the strength of a refractory in a molten slag a from being degraded and to prolong the service life of the refractory by heating a refractory material consisting of aluminum oxide and silicon carbide in a gaseous nitrogen atmosphere to nitride a residual silicon matter. CONSTITUTION:This refractory is produced by firing the refractory material consisting of 5-40wt.% silicon carbide and balance aluminum oxide, molten slag resistance is improved by heating the material in the gaseous nitrogen atmosphere to nitride the silicon matter remaining in the silicon carbide. The refractory is specified as <5% content of Si2ON2 at the cross-section of the refractory by half-value width method in the measurement of X-ray diffraction. In the refractory, when the content of carbon is controlled to <=25wt.%, the bending strength of the refractory is prevented from being degraded.

Inventor: IKUTA KOJI
IPC: G01R31/36
Filed: 1990-03-26
Abstract: PURPOSE:To enable accurate judgement of the lifetime of a lead storage battery employed in a floating charged state by measuring an internal impedance of the lead storage battery by subtracting a measured current of an internal impedance measurer from a ripple current contained in a charging current and by dividing a measured voltage of the internal impedance measurer by a difference current. CONSTITUTION:A ripple current contained in a charging current of a lead storage battery 3 connected in a floating charged state through a rectifier 2 is subtracted from a measured current of an internal impedance measurer 6. In other words, an AC ammeter is inserted into a charging circuit of the lead storage battery 3 and a measured value of this AC ammeter 5 and a measured value of an AC ammeter 6-2 of the internal impedance measurer 6 are inputted to a subtractor 7, so as to calculate a difference current. Then, the measured voltage of the internal impedance measurer 6 is divided by this difference current and a value thus obtained is indicated as an internal impedance. By this constitution, the internal impedance in the floating charged state can be measured accurately.

Abstract: PURPOSE:To obtain a small-sized and inexpensive polarization plane controller by disposing 1st and 2nd polarizing means in place of a Faraday element as a polarization plane control element and disposing an electrooptic element and a polarized beam splitter behind said element. CONSTITUTION:Light from a light source 1 to be measured is bisected by a branching filter 21. One thereof enters an acoustooptic optical modulator 3 by which the light is shifted to enter the 1st polarizing means 23a. A voltage is impressed to the respective elements of the means 23a by which the polarization plane is rotated. This light is circularly polarized by the electrooptic element 24a and is linearly polarized by the element 24b. The light is then entered to the polarized beam splitter 26a to allow transmission of the P wave. This light is entered to an optical coupler 27. On the other hand, the incident light on a delay optical fiber 22 enters the 2nd polarizing means 23b. A voltage is impressed to the electrooptic elements 24c, 24d and the splitter 26b by which the light from the fiber is so controlled as to transmit the splitter 26b at a higher rate. The transmitted light enters the coupler 27. The light interferes with the previous P wave and is converted by a photoelectric converter element 28a to an electric signal which is sent to a measuring instrument.

Filed: 1982-05-12
Abstract: PURPOSE:To prevent a powder from adhering to a circumferential wall of a metering chamber and from forming a film thereon, by arranging, on an outer circumferential surface of a metering vessel that will be rotated, a plurality of scraping pieces in a staggered manner that will slide on the circumferential wall of the metering chamber. CONSTITUTION:The plurality of scraping pieces 14 that will slide on the surface of the circumferential wall 7 of the metering chamber are arrange in a staggered manner on the outer circumferential surface of a cylindrical section 13 of the metering vessel 12 such that groups each consisting of three and two such scraping pieces 13 are spaced circumferentially by 60 deg. and at two points they cover longitudinally thoroughly said outer circumferential surface. Thus, if a powder enters a gap between the outer circumferential cylindrical section 13 and the circumferential wall the powder would not be compacted and therefore it would not adhere to the circumferential wall 7. If the powder adheres, it would be scraped off by the scraping pieces 14 and is discharged outside of said gap.

During its one turn this cam 27 oscillates a lever 41 by way of a high level part 27b, thereby releasing the detention of the lever 42. When the cam 27 makes 1 turn, the lever 34 is detained by the lever 42 and the cam 27 stops.

Filed: 1984-04-20
Abstract: PURPOSE:To suppress the generation of a latch-up phenomenon on a CMOS (complementary metal oxide semiconductor) by a method wherein a current amplification factor is lowered and the generation of a positive feed back is suppressed by increasing the impurity density of the base of a a parasitic bipolar transistor and by lowering the injection efficiency from an emitter, and the resistance entering in parallel between the emitter and the base is reduced, thereby enabling to prevent voltage drop even when a current flows said resistance part. CONSTITUTION:The circumferences of an n-channel, the n<+> region which is the source of a p-channel MOS transistor, and a p<+> region are surrounded by the conductive layers 23 and 28 of the conductive type reverse to that of the source, and this constitutes a structure wherein the same potential is given to the sources 4 and 7 and reverse conductive type layers 23 and 28 from the surface of a substrate. As a result, the current amplification factor of a parasitic bipolar transistor and the resistance entering between an emitter and a base in parallel is made smaller, and a trimming current is increased, because a latch-up is generated, thereby enabling to suppress the generation of a latch-up.
