Title: Semiconductor superlattice structure
Inventor: IWATA HIROSHI
IPC: H01L21/203
Filed: 1986-06-18
Abstract: PURPOSE:To enable semiconductor super-lattice structure to be formed having electrical conductivity high also in the direction vertical to layers, by making the energy levels at the band ends of the second semiconductor layers be identified with the deep levels in the first semiconductor layers. CONSTITUTION:The first semiconductor layers 11 made of semiconductor materials having deep levels, and at least two or more of the second semiconductor layers 12 made of semiconductor materials having no deep level, are piled alternately so that energy levels at the band ends of the second semiconductor layers 12 are made to be identified with the deep levels in the first semiconductor layers. Because the second semiconductor layers 12 are lower in potential than the first semiconductor layers, energy levels of quantum mechanics are generated in the thin layers 12 of the second semiconductor. Because these energy levels are identical with the deep levels in the first semiconductor layers 11, carriers in the second semiconductor layers 12 can be made to easily enter the deep levels in the first semiconductor layers 11 and be moved to the neighboring first semiconductor layers 11. Hence, electric charges can be carried in the direction vertical to the layers, and a polarity in the superlattice structure can be changed by the polarities of the second semiconductor layers 12.

Inventor: KOTANI TOSHIHIRO
IPC: C30B15/00
Filed: 1987-06-11
Abstract: PURPOSE:To prevent the deposition of a CdTe crystal on the inner wall of a chamber and to surely monitor the inside of the chamber by coating liq. B2O3 on the inner wall of the crystal growth chamber before the CdTe-based crystal is pulled up by the hot-wall method. CONSTITUTION:A CdTe crystal or a mixed crystal contg.

IPC: G06T1/00
Filed: 1982-08-23
Abstract: PURPOSE:To improve the sound pressure of a transmitted acoustic wave and to improve OS/N by a method wherein a signal of a time corresponding to a time for propagation from an assumed sound source to a wave-receiving element is arranged on a plane and reception signals are added sequentially on a two- dimensional plane. CONSTITUTION:An assumed sound source is formed at a point Q. Reflected waves from an object are received by a group 4 of wave-receiving elements. A signal Rn among these reception signals is digitized by an A/D converter 5 and stored in a primary memory 6. Coordinate data delivered from a control unit 1 are converted into separate coordinate signals by a subtractor 7. By combining these signals and reading a reference table 8, time data corresponding to the arrangement thereof are delivered therefrom. These data are added to separate values obtained from the control unit 1 and thereby a time is obtained. By controlling the primary memory 6 by the value of this time, a value at the time of a signal received by an n-th element is obtained. This value is arranged additively at a point on a regenerative screen 11 by using an adder 10. All transmission waves are processed repeatedly in this way.
