Title: Ceramic composite material and its production
Inventor: SASAKI HIROSHI
IPC: C04B35/80
Filed: 1988-12-19
Abstract: PURPOSE:To improve the strength and toughness of the ceramic composite material by dispersing the SiC fine particles having a specified diameter and the SiC whiskers having a specified diameter in the crystal grains of an MgO matrix having specified size. CONSTITUTION:The SiC fine particles having <=1.0mu diameter and the SiC whiskers having <=3mu diameter are dispersed in the crystal grains of the MgO matrix having 0.5-100mu size to obtain the ceramic composite material. The material is produced by mixing the MgO pulverized to <=5mu particle diameter, the SiC pulverized to <=1.0mu particle diameter, and the SiC whiskers having <=3mu diameter, and calcining the mixture. Since the SiC fine particles are dispersed in the crystal grains of MgO, residual stress is produced due to a difference in the thermal expansion between both materials, hence the cracking of MgO is prevented, and the high-temp. strength is improved. In addition, the drawing effect of the SiC whiskers is simultaneously generated, and high toughness is obtained.

Title: Externally synchronizing programmable device
Inventor: SHIZUKUISHI MAKOTO
IPC: H03L7/08
Filed: 1989-12-11
Abstract: PURPOSE:To easily realize an externally synchronizing system with a small number of parts by inputting both external and internal signals to a phase comparator in order to produce the signals showing the gain or the loss of phases the external and internal signals. CONSTITUTION:A voltage control oscillation circuit 6 produces a signal S3 having an oscillation frequency fZ corresponding to the voltage of a signal S0 outputted from a low pass filter 5. A 1/N frequency dividing circuit 1a divides the signal S3 down to 1/N and outputs an internal signal S2. A phase comparator 3 detects the difference of phases between both signals S1 and S2, and a signal corresponding to the phase difference is outputted from a charge pump circuit 4. Furthermore the signal S0 integrated by the filter 5 is outputted. This feedback control is automatically repeated so that the phase difference between the external signal S1 and the internal signal S2 is set at zero and the external synchronization is attained to the signal S1. Thus it is possible to easily obtain an externally synchronizing system with a small number of parts.
