Patent JP-H03200374-A (JP)
Title: Manufacture of solar cell
Inventor: ICHIKAWA YUKIMI
IPC: H01L31/04
Filed: 1989-12-27
Abstract: PURPOSE:To suppress a decrease in an open voltage when an i-type layer film is thin and to improve conversion efficiency by forming an i-type layer on a p-type layer on a substrate, exposing the surface of the i-type layer during hydrogen gas discharging, and then laminating an n-type layer. CONSTITUTION:A transparent texture electrode 21 made of an SnO2 and having a large scattering degree is formed on a glass board 1, a p-type layer 3 made of an a-SiC is formed therein, then a p/i boundary layer 8 made of i-type quality a-SiC is deposited therein, and further an i-type a-Si layer 4 is deposited thereon. After hydrogen discharging is conducted, an n-type layer 5 is deposited, an Ag film is further formed, and a rear surface electrode 6 is formed. Thus, a decrease in an open voltage due to the defect of the layer 4 generated when a solar cell having the relatively thin p-i-na-Si layer of the layer 5 is formed on the electrode 21 having a vigorously uneven surface and a large scattering degree can be suppressed by hydrogen discharging the layer 4 before the layer 5 is deposited. Thus, the decrease in the open voltage when the i-type layer is thin can be suppressed to improve conversion efficiency.

Title: Psk demodulator, psk demodulation method and recording medium
Inventor: SAKURAI NORIYOSHI
IPC: H04L27/22
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a PSK demodulator and a PSK demodulation method to accurately demodulate a high-speed PSK modulation signal without the need for using an analog filter. SOLUTION: A sampling unit 5 applies binary processing to a QPSK modulation signal that is amplified and frequency-converted and the resulting signal is fed to a delay device 7 and a detector 8. The delay device 7 delays the modulation signal received by itself by 1 symbol and gives the delayed signal to the detector 8. The detector a generates a detection signal denoting a time difference between a leasing of a signal fed from the sampling unit 5 and a leading of a signal fed from the delay device 7. A shift register 9 latches a logical value denoted by the detection signal in prescribed timing, a 4-value converter 11 converts the logic value latched by the shift register 9 into 2-bit data according to a prescribed rule and restores the data to the original data subjected to QPSK modulation. A local oscillator 4 and/or a sampling signal generator may be controlled by a PLL.
