Title: Prereducing process for chromitite
Inventor: ISHIKAWA MINORU
IPC: C22B34/32
Filed: 1985-12-23
Abstract: PURPOSE:To prereduce a chromitite at a low cost, at a high reduction rate, and with high productivity by crushing a chromitite, a specific proportion of carbon material, and proper amounts of prereduced substance with proper reduction rate, by mixing the above, and by reducing the mixture in powder condition or in pelletized state in a prereducing furnace. CONSTITUTION:The chromitite and the carbon material such as coke, etc., in an amount of 10-40% of the chromitite are crushed and blended. The resulting mixture is preheated in the powder condition or after pelletized by means of a pelletizer with the addition of a binder and water and is charged into the prereducing furnace such as fluidized-bed reducing furnace, rotary kiln, etc., where the above chromitite is reduced in the solidus state with regulating the furnace temp. to 1,100-1,400 deg.C. In the above prereduction process, 3-30% prereduced substance with 20-90% reduction rate is circularly used are raw material and mixed in the crushing stage. In this way, prereduction velocity is decreased and reduction velocity is increased, so that cost of reduction can be reduced and also reduction rate can be improved.

Abstract: PURPOSE:To reduce the memory capacity for a table and to reduce the cost by forming the table to generate the number of consecutive numerals of 1 of a code word, remaining code words and code length based on input data. CONSTITUTION:An optimum Huffman table is generated based on data received by an input device 105.

Title: Nonvolatile semiconductor storage device
Inventor: TERADA YASUSHI
IPC: G11C16/06
Filed: 1987-11-16
Abstract: PURPOSE:To reduce the number of elements by using three N-channel MOS transistors TRs to select a high level or a low level as the output of a row decoder which should be applied to a boosting circuit. CONSTITUTION:At the time of write, a clock 2 goes to the high level and a clock 1 goes to the low level, and the source of a TR 8 is earthed. Therefore, only a word line selected by the row decoder is earthed. Since non-selected word lines become floating gates, they are boosted to 1/2VPP by a high-voltage switch consisting of TRs 3 and 4 and a capacitor 7. At the time of read, the clock 1 goes to the high level and the clock 2 goes to the low level, and the source of the TR 8 is charged, and only the selected word goes to the high level. Since three N-channel MOS TRs 8-10 are used to select the high level or the low level as the output of the row decoder applied to the boosting circuit, the number of elements of the word line high-voltage switch is reduced.

Title: Digital reader for analog signal
Inventor: IGUCHI HIROSHI
IPC: H03M1/12
Filed: 1990-10-25
Abstract: PURPOSE:To detect the failure of an analog sensor and to eliminate the influence on the elimination effect of a high frequency component of a low pass filter by giving a signal representing abnormality in the case of deviation of an input analog signal before it is given to the low pass filter from a prescribed range with an abnormality detection means to a control means. CONSTITUTION:The abnormality detection means (window comparator circuit 5) compares an input analog signal before it is given to a low pass filter (anti- aliasing filter circuit 4) with a signal specifying a prescribed range and gives signal representing it when the input analog signal is deviated from the prescribed range to a control means (CPU 120). That is, the control means (CPU 120) discriminates the abnormality by a signal indicating the abnormality. Thus, the abnormality of the analog sensor is detected earlier by not through the low pass filter (anti-aliasing filter circuit 4) and the influence on the elimination effect of a high frequency component of the low pass filter (anti-aliasing filter circuit 4) is avoided.
