Title: Photoelectric converting semiconductor device
Inventor: YOSHIDA SUSUMU
IPC: H01L31/0687
Filed: 1989-02-17
Abstract: PURPOSE:To enhance the crystallizability of an upper solar cell as well as reducing the resistance loss in a junction part by a method wherein a buffer layer is composed of a semiconductor material in larger forbidden band width than that of the semiconductor material comprising the upper solar cell while a tunnel junction part is provided in the buffer layer. CONSTITUTION:A buffer layer 60 for crystal lattice matching is composed of a semiconductor material in larger forbidden width than that of the semiconductor material comprising an upper solar cell 20 while a tunnel junction part 55 is provided in the buffer layer 50. Through these procedures, the transmittivity of the solar beams in the buffer layer 50 is enhanced without deteriorating the crystallizability of the upper solar cell 20, i.e., the solar beams are not absorbed in the buffer layer 50; the solar beams can be photoelectrically converted efficiently by the underlying lower solar cell 10; thus the upper solar cell 20 and the lower solar cell 10 can be electrically junctioned very well so that the resistance loss in the said junction part 55 may be reduced.

IPC: H04N9/72
Filed: 1994-03-10
Abstract: PURPOSE: To automatically control the trigger position of a clamp signal by discriminating the existence of a synchronizing ON green signal and outputting a logic signal. CONSTITUTION: When a green signal or a synchronizing ON green signal is inputted to a synchronizing signal separation part 10, the separation part 10 separates a synchronizing signal and supplies the separated synchronizing signal to a synchronizing selection part 11. When the synchronizing signal outputted from the separation part 10 and a horizontal/vertical synchronizing signal are simultaneously inputted, the selection part 11 outputs a synchronizing signal selectively inputted by previously set priority to a clamp signal control part 30, a clamp signal generation part 29 and a horizontal/vertical synchronization separation part 13. The generation part 29 triggers a clamp signal at the edge of the synchronizing signal and outputs the triggered clamp signal.  At the time, the control part 30 inputs signals outputted from the separation part 10 and the selection part 11, discriminates the existence of the synchronizing signal and then controls the clamp signal generated from the generation part 29. Thereby the trigger position of the clamp signal can be automatically controlled.

The switches 3a, 3b are opened and closed by a timing circuit 6. When the current is supplied to the lead 1, leakage to the sensitive material 2 occurs so that the gas detection signal is lowered However, the S/N ratio is increased since the measurementn is perfomed with the switches opened. Since the switches are provided to the lead part, the sensitive material is heated uniformly so that the gas concentration can be measured accurately.
