Title: Production of magnesia porcelain
Inventor: ANAZAWA MASAAKI
IPC: C04B35/04
Filed: 1992-08-25
Abstract: PURPOSE:To easily obtain a dense magnesia porcelain. CONSTITUTION:In producing primary granules by pulverizing fused or dead- burned magnesia, water is added to the raw material to perform partial slaking so as to be 5-15wt.% in the partial slaking level for the surface of the primary granules, and water is added to the resulting primary granules into a slurry followed by granulation and drying to produce secondary granules, which are then calcined. Thereby, in the granulation, a non-aqueous solvent such as an alcohol is not required, thus enabling the granulation at a low cost along with no need for any pollution control equipment, etc. Partial slaking in the above- mentioned way enables production of the secondary granules of good fluidity. The secondary granules are highly excellent in sinterability and the grain boundaries of the resulting sintered granules are also extremely small.

Title: Digital modulator
Inventor: ONISHI TERUO
IPC: H04L27/20
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To decrease the interrupting frequency that is required for output of the DSP data a compared to a conventional system and to reduce the DSP thorough by placing a FIFO between a DSP and a D/A converter and performing the data write and read operations synchronously with each other to the DSP and the D/A converter respectively. SOLUTION: A base band modulator 1 converts the transmission data into base band I and Q signals. A 1st multiplier 4 multiplies the I signal that undergone its band limitation via an orthogonal converter 2 by a cosine wave of frequency fL, and a 2d multiplier 5 multiplies the Q signal by a sine wave of frequency fL. Then the outputs of both multipliers 4 and 5 are added together by an adder 8 so that a digital modulation output signal of center frequency fL is obtained. A DSP outputs at a time the signals which are not up-sampled yet at an interval of sapling frequency fs1 and the zero-interpolated data to a FIFO 15. In other words, the FIFO 15 performs the at a write and read operations synchronously with each other to the DSP and a D/A converter 16 respectively.
