Title: S/n detection circuit
Inventor: TAMURA TOSHIO
IPC: H04B17/336
Filed: 1992-01-17
Abstract: PURPOSE:To accurately detect the S/N by turning a low-pass filter to a narrow band by making the pass band of the low-pass filter on one detection axis narrower than the pass band of the low-pass filter on the other detection axis. CONSTITUTION:The pass band of a low-pass filter on one detection axis is made narrower than that on the other detection axis. In short, the phase fluctuation component of one detection axis (axis I) becomes weak and the phase fluctuation component of the other detection axis (axis Q) becomes remarkable by the control of a phase comparator 6. The phase fluctuation component on the axis I is made light of compared with the phase fluctuation component on the axis Q. In this case, the low-pass filter 3 on the axis Q is needed to be set in the wide band so as to obtain the synchronization range of the phase- locked loop. The low-pass filter 2 on the axis I requires the small range of the phase-locked loop so that it can be set to the narrow band. Thus, the C/N can be set high, resulting in expanding the range of the low limit value of the S/N.

Title: Solar cell
Inventor: OTSUKA HIROYUKI
IPC: H01L31/04
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce a surface re-combination rate of a semiconductor/insulating film interface and to improve conversion efficiency by providing a semiconductor having a work function different from that of a semiconductor layer having a wider forbidden band width than that of an insulating member or that of a semiconductor serving as a solar cell. SOLUTION: A solar cell consists of a semiconductor A (solar battery) 1, an insulating member (or a semiconductor C having a wider forbidden band width than that of the semiconductor A) 2 and a semiconductor B3. It is important to provide the semiconductor B3 having a higher work function than that of the semiconductor A1. It is of course possible to reduce surface re-combination even if the solar cell consists entirely or partly of the semiconductor A (solar battery) 1 and the semiconductor B3 without the insulating member 2 or the semiconductor C. Moreover, by providing the semiconductor B3 having a lower work function than that of the semiconductor A1 serving as a solar cell, the electron density in the vicinity of the surface can be increased.
