Title: Production of fenb of low nb contents
Inventor: SHIBATA YUUJI
IPC: C22C33/00
Filed: 1978-03-10
Abstract: PURPOSE: To produce Fe-Nb of Nb; 16 to 20% whithout decreasing the yield of Nb by mixing metal iron, iron oxide, metal Al in the form of powder to Fe-Nb of Nb>55% and letting the mixture undergo thermit reaction.  
     CONSTITUTION: Fe-Nb of Nb>55% is crushed to sizes of 1 to 5 mm. For this, scraps of low carbon steels and iron oxide of mill scales, etc. are used. In this case, the iron oxide becomes the oxygen supply source of thermit reaction. To this is added powder Al of 100 to 105% of thermoretical reaction quantity of iron oxide to oxygen and further a slag making agent such as lime or other is added at a suitable amount and these are mixed. This mixture is filled in a vessel made of refractories and is then ignited to cause thermit reaction between the Al and iron oxide. The mixture melts by reaction heat and the iron oxide is reduced, by which Fe-Nb of Nb; 16 to 20% may be obtained. Since the Fe-Nb is used without using Nb 2 O 5 , the yield of Nb is extremely high.

Inventor: HAMAGURI KENJI
IPC: G01N21/31
Filed: 1982-02-19
Abstract: PURPOSE:To make possible an accurate measurement for the variation in a wide range of the quantity of coloring matter in blood, by finding a primary function or its approximate value of a square value of the ratio of two operational results for two kinds of wavelength. CONSTITUTION:Light from a light source 1 of a wide wavelength zone transmits a part to be measured 2 of a living body and said light is made incident into interference filters 3, 4 and signals of different center frequency of each filter are introduced into photoelectric conversion parts 5, 6 and then, each intensity of transmitted light is detected. Then, an output of each conversion part takes a form overlapping an alternating current component to a direct current component because the quantity of the arterial blood of a living body is varied by heartbeats. Information of dimensions of relative variation width of the alternating current component of a detection signal is extracted by calculating parts 7, 8 and these values of the information are squared by each square circuit 9, 10 and the ratio is found by a division circuit 11. Moreover, a multiplier A1 is multiplied by a primary function operation circuit 12 and a constant B1 is added. This result is displayed as a saturation degree of oxygen.

Abstract: PURPOSE:To simplify the recording and reproduction of digital signals other than recorded data so as to improve the function of a digital signal recorder and reproducing device, by providing a memory which receives and delivers data between a buffer memory and DMA. CONSTITUTION:In accordance with a command from a system controller SC21, a CPU19 writes a test signal in a memory 31 and holds a corresponding expected value signal. The signal of the memory 31 is transferred to a buffer memory 2. Then the memory 2 is set to a condition where only reading out operations are performed and recording on a magnetic tape is performed. A buffer memory 16, memory 33, and buffer controller 34 at the reproducing side also make similar operations. The reproduced test signal transferred to the memory 33 is fetched into the CPU19 and collated with the expected value signal. By means of the collation, the erroneous condition of a recording and reproducing route is measured and the measured result is displayed on and recorded in the SC21.

Title: Voltage controller for generating apparatus for car
Inventor: TANIGUCHI TAKESHI
IPC: H02P9/14
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To cancel variation in an exciting voltage by arranging a multiplier at an intermediate part between a saw-tooth-wave generating circuit and a comparator and connecting a battery to this. SOLUTION: A multiplier 30 outputs the product VTR2 of a value obtained by dividing the voltage of a battery 8 by a rated voltage and normalizing it, and the output VTR1 of a saw-tooth-wave generating circuit 25 which outputs a voltage proportional to the square of the frequency of a generator 3. A comparator 24 compares the outputs of an error amplifier 23 and the multiplier 30. Besides, an output circuit 26 amplifies on/off signals from the comparator 24, and controls the exciting voltage of the field winding of the AC exciter 3b of the AC generator 3, and in consequence the output voltage of the AC generator 3 is controlled to a set value set by a voltage seller 22.  Since the amplitude of a saw-tooth-wave to be compared with the output signal of the error amplifier 23 is proportional to the voltage of the battery 8, the on-duration of a square-wave outputted from the comparator 24 is inversely proportional to the voltage of the battery 8. Accordingly, variation of an exciting voltage by voltage variation of the battery 8 can be canceled, so the terminal voltage of the generator does not vary, even if the voltage of the battery 8 varies.

Filed: 1988-02-08
Abstract: PURPOSE:To make it possible to comparatively observe the conditional change of a specimen with change in external events by letting the external events be changed while being synchronized with excitation scanning, and thereby letting measured data obtained with change in the external events be memorized into each memory area by means of time division. CONSTITUTION:Memory areas 2a through 2h by which measured date are to be memorized are selected in advance for a memory means 2 depending on the condition of external events to be observed by means of a memory area selecting means 4. And whenever an exciting line scanning signal is inputted, a drive signal for change in the external events is produced by a drive signal producing means 14 while being synchronized with the scanning signal. This situtation thereby allows the external events to be changed with a constant period maintained while being synchronized with the exciting line scanning. In addition, the memory areas which have already been selected are switched over in order while being synchronized, a write address for each selected memory area is generated from an address generating means 24 while being synchronized with the switch-over of the memory area. This constitution thereby makes it possible to allow each measured data corresponding to change in the external events to be memorized into each memory area by means of time division.

Abstract: PURPOSE:To reduce the noise of an AC motor by consuming the vibration energy of a core by the bonding surface of the rib of a stator core to that of a frame to be attenuated, thereby reducing the amplitude of a vibration. CONSTITUTION:Predetermined number of axial ribs 3 are formed along the outer periphery of a laminated core.
