Title: Thin film semiconductor device and manufacture thereof
Inventor: MIZUNO SHINICHI
IPC: H01L31/0236
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To obtain a thin film semiconductor device wherein the light absorption efficiency and the photoelectric conversion efficiency can be raised in a single crystal Si thin film solar cell, etc. SOLUTION: A transparent thin plastic film base 14 is disposed on the opposite surface of a solar cell element 10 to a plastic film base 12. A diffraction grating 15 disposed between the plastic film base 14 and the cell element 10 has a reflection type brazed grating structure made of a conductive material such as Al. An incident light is diffracted by the grating 15 and returns to the cell element 10. If this diffraction angle exceeds a certain value, the angle making with a normal to the solar cell increases enough to totally reflect it on the top surface of an Si thin film layer (solar cell element 10) or the surface of the transparent plastic film base 12 and it returns to the cell element 10. Such process of returning to the cell element 10 is repeated to confine the light in the interior of the cell element 10.

Filed: 1991-04-30
Abstract: PURPOSE:To allow one circuit to eliminate the noise of both a luminance and a chrominance signal by filtering a high frequency component from the noise component of a multiplex signal and subtracting the high frequency component from the input luminance signal and the input chrominance signal. CONSTITUTION:A 2nd subtractor 55 subtracts the output noise component of a coefficient device 54 from the multiplex signal from an adder 51 and sends the result to a signal delay memory 52. On the other hand, a 2nd HPF 33 separates a high frequency component from a noise component of the output of a coefficient device 54 and adds the component to a 3rd subtractor 34 and the high frequency noise component is subtracted from the luminance signal at a luminance signal input terminal 31. Thus, the residual signal is outputted from a luminance signal output terminal 35. Furthermore, a 2nd LPF 44 separates a low frequency component from a noise signal outputted from the coefficient device 54 and adds the component to a 4th subtractor 45, the low frequency noise component is subtracted from the input chrominance signal via a 1st phase shifting device 42 to obtain the chrominance signal after noises are eliminated. Thus, one circuit is enough to eliminate the noises of both the luminance signal and the chrominance signal.

Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To improve exciting efficiency and oscillating efficiency without using a dielectric film by setting the incident angle of a laser-light reflecting. means arranged at an exciting laser-light input part in a ring-shaped resonator at a Brewster angle. SOLUTION: A 45 deg. total reflection prism 10 is arranged on the optical axis pattern or the laser light emitted from two beta barium borates(BBO) crystals 4 and 8, which are nonlinear crystals, The direction of the oscillated laser light is changed by 90 deg. and applied into an input/output mirror 1 at a Brewster angle. Here, the phases of two BBO crystals 4 and 8 are aligned at a type 1. The oscillated lights emitted from these crystals become the vertically polarized lights. Therefore, when the vertically polarized lights enter into the input/ output mirror 1 at the Brewster angle, the vertically polarized lights are reflected at the high reflectivity in the input/output mirror 1, and the amount of the light cycling a ring-shaped resonator 104 again is increased.  Therefore, the exciting efficiency and the oscillating efficiency at the ring-shaped resonator 104 are improved, and the threshold value of the oscillation can be lowered.
