Title: Method for accurately keeping low alumina content in molten salt electrolytic cell for producing aluminum
Inventor: MISHIERU RUROWA
IPC: C25C3/20
Filed: 1986-05-07
Abstract: A process is disclosed for accurately maintaining a low alumina content of between 1 and 4.5% in a cell for the production of aluminum by electrolysis in the Hall-Heroult process. According to the invention, a control parameter P=-1/D(dR1/dt), is determined, wherein D is the variation in the alumina content of the electrolytic bath in % weight per hour, R1 is the internal resistance of the cell, and t is the time. A series of operations is then carried out in a repeated cycle, starting with the cell being fed alumina at a nominal rate which is substantially equal to the quantity consumed by electrolysis. At periodic intervals, an over-supply of alumina is added in order to enrich the bath, and the over-supply is continued for a preset time during which dR1dt is negative. The feed rate is then reduced to less than the nominal feed rate, during which time dR1dt passes through zero to become positive and the regulation parameter P, the value of which tends to rise, is measured often. The successive values of P are compared with a required preset value Po. As soon as P equals Po, the feed rate is returned to the nominal feed rate and a new cycle is recommenced.

Title: Particle measuring apparatus equipped with cyclone converged body
Inventor: JAE-KAN JEON
IPC: G01N1/22
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To obtain a particle measuring apparatus by which the number of dust particles can be measured with reference to the sample air in a large volume by installing a cyclone converged body which increases the volume of the sample air at a sample-air inflow port. SOLUTION: When a pump 2 is driven, an air current which is passed through a particle measuring apparatus 1 connected to the pump is generated, and an air current is generated inside a cyclone converged body 9 connected to the particle measuring apparatus 1 by a suction pipe 5 and a converged pipe 10. Dust particles which are concentrated near the inner wall of the cyclone converged body 9 flow into the converged pipe 10 through a particle bypass pipe 11 together with the air current, and, in succession, they flow into the particle measuring apparatus 1 through the suction pipe 5 connected to the converged pipe 10 so as to be measured. Thereby, without lowering a measurable particle size due to the measurement of the air in a large volume, the air in the large volume is sampled as a sample, and the particles to a particle size of 0.1μm can be measured in a short time.  Consequently, as compared with a conventional particle measuring apparatus 1, a measured result of high reliability can be obtained.

Title: Method for observing earthquake and strong wind for structure
Inventor: SASAKI NOBUYUKI
IPC: G01M99/00
Filed: 1994-05-20
Abstract: PURPOSE:To maintain a device in a normal operating state by confirming the operating state of a sensor and data recording device by always storing all measuring data temporarily in the data recording device. CONSTITUTION:Measured values A1 of each element such as the wind velocity (v), seismic acceleration alpha, acceleration of response beta or displacement and stress of each element are calculated by suitably analyzing and processing 4b measuring data after successively sending the data to an observation room 2, amplifying 6 the data, and then, recording 4a the data. Then each measuring value A1 is compared 4c with each preset reference value A0, namely, v0, alpha0, and beta0. Only when A1>=A0, the data are accepted, stored, and kept 4b. The data stored and kept (4b) are fetched at appropriate time intervals and the content of the data is checked and whether or not a device operates normally is confirmed. When the data contain a questionable point, its cause is cleared up and the defective part is remedied. Therefore, the external forces acting on an objective structure and the response of the structure to the external forces can be measured without omission through a year and, in addition, the measuring data are appropriately discriminated and only necessary data can be kept.

Title: Photoencoder
Inventor: MATSUMOTO HIDETOSHI
IPC: G01D5/26
Filed: 1985-05-17
Abstract: PURPOSE:To make a special adjusting work unnecessary by providing a current amplifying means, a peak value holding means, and a comparing means which outputs a binarization signal in a photodetecting circuit of a photoencoder. CONSTITUTION:When passing a slit disc (omitted in the figure) to strike a photodiode, the light from an LED 1 tries to flow a current I to the negative terminal of the first operational amplifier 3. However, the current I is flowed to an output terminal P through a resistance R2 because the input impedance of the operational amplifier 3 is sufficiently high. At this time, the voltage in the output terminal P of the first operational amplifier 3 is made lower than a reference voltage Vr by a voltage drop P2I of the resistance R2, and the output of the operational amplifier 3 becomes a waveform (a) approximating a sine wave. Since resistances R3 and R4 have the same value, the input of the positive terminal of the second operational amplifier 5 has a half amplitude of the output of the operational amplifier 3 and is as shown by a broken line (b). In a peak value holding circuit 8, the second operational amplifier 5 and a diode 6 constitute a buffer, and the buffer holds the negative peak value of the amplitude at a connection point A, and this value [indicated by a broken line (c)] appears at a connection point B.

Abstract: PURPOSE:To facilitate the grasping of a memory cycle by setting a chip address to a program means and deciding the selection of a chip based on whether or not an address signal coincident to the chip address is inputted. CONSTITUTION:The chip address set to program circuits 7 and 9 and address signals An+1 and An+2 supplied from the external part are compared with comparing circuits 11 and 13, and when the coincidence is obtained, the coincident signal of an L level is outputted.

Therefore, for DRAM 1, the signals An+1 and An+2 coincident to the chip address set to the circuits 7 and 9 are supplied and when the signal RAS* is at L level, the chip is selected. Thus, an external TTL circuit to form in correspondence to 1:1 for each semiconductor memory can be made unnecessary.

Filed: 1990-04-23
Abstract: PURPOSE:To produce a nonoriented silicon steel sheet having high magnetic flux density and low iron loss by incorporating small amounts of Sn and Cu simultaneously into a steel and controlling the finishing temp. of hot rolling. CONSTITUTION:A steel has a composition consisting of, by weight, <=0.010% C, 0.1-2.0% Si, 0.1-1.5% Mn, 0.1-1.0% Al, 0.02-0.20% Sn, 0.1-1.0% Cu, and the balance Fe with inevitable impurities. The hot rolling of this steel is finished at a temp. in the range between (Ar3 point - 20 deg.C) and (Ar3 point + 50 deg.C). Then, the resulting plate is subjected to hot rolled plate annealing at a temp. not higher than the Ac1 point or to self-annealing. Subsequently, the plate is cold-rolled once or is cold-rolled two or more times while process-annealed between the cold rolling stages, followed by continuous annealing. Further, skin pass rolling is carried out at 2-12% reduction of area, if necessary. By this method, the nonoriented silicon steel sheet having high magnetic flux density and reduced in iron loss can be obtained.
