Title: Compound semiconductor substrate
IPC: H01L21/205
Filed: 1992-03-20
Abstract: PURPOSE:To provide a compound semiconductor substrate which has reduced crystal defects, such as dislocation. CONSTITUTION:Based on TMA, an AlAs layer 3 is caused to grow by one half the width of terrace on an Si substrate which is off by 1 to 4 deg. in the direction of [110] from the plane (001). Then, a GaAs layer 2 is caused to grow by one half the width of terrace based on TMG. Fractional super lattices for the AlAs layers 3 and the GaAs layers 2 are formed with a required film thickness on the Si substrate by repeating this process. The AlAs layers 3 are selectively etched and eliminated. There are formed extremely fine particle GaAs layers 2 in the shape of stripes on the Si substrate. A compound semiconductor thin film, a GaAs film 4 is caused to grow on the semiconductor substrate formed in this manner. The GaAs film 4 does not grow on the Si substrate 1. The GaAs film meets with the progress of growth. Furthermore, as the film thickness of the GaAs film 4 is increased, the uneven surface of the GaAs film 4 is relaxed and flattened where clearances 5 are formed between the stripe- shaped GaAs films 2.

Title: Control rod driving mechanism for nuclear reactor
Inventor: MASE NORIAKI
IPC: G21C7/16
Filed: 1980-07-14
Abstract: PURPOSE:To make the continuous and precision measurement of the control rod position of a nuclear reactor possible by flowing pulse current to a wire contained in a magnetic pipe, and utilizing the torque wave generated at that time by the mutual effect with a magnet placed on the outside. CONSTITUTION:Pulse current is flowed to a wire contained in a tube of a magnetic substance, and the torque by Wiedemann effect is generated by the effect with a magnet placed on the outside, then the time up to the reception of torque wave is measured, and the position thereof is detected. For example, a magnetic pipe is put into a protecting pipe 13, and a wire 13 is further contained therein. When pulse current is flowed to this through an adapter 16, torque is generated by the mutual effect with a magnet 3 on the outside. The position of the magnet is detected by the time difference from the transmission of the pulse current until the reception of the torque wave. If such mechanism is attached to a control rod driving mechanism for nuclear reactors, the position of the control rod is measured continuously and accurately with the relatively simple device.
