Title: Rectifier circuit
Inventor: KIMURA KATSUHARU
IPC: H02M7/217
Filed: 1991-11-28
Abstract: PURPOSE:To provide a rectifier circuit realizable with semiconductor integrated circuits having circuit configuration without a clock signal. CONSTITUTION:A polarity judging circuit 7 judges the polarity of AC signal voltage, and generates a first DC signal and a second DC signal having a predetermined specified DC voltage difference which differs with the polarity, positive or negative. A first differential amplifier circuit 8 having two sets of differential pair transistors performs the differential amplification of the AC signal and the first DC signal, and generates a first differential output signal. A second differential amplifier circuit 9 having the same circuit configuration as that of the first differential amplifier circuit 8 performs the differential amplification of the AC signal and the second DC signal, and generates a second differential output signal. And a rectified signal is obtained by reversely-combining the first and second differential output signals.

Title: Formation of semiconductor thin film
Inventor: TATSUMI TORU
IPC: H01L21/203
Filed: 1989-12-28
Abstract: PURPOSE:To enable a regrowth film in excellent crystallinity to be formed while preventing Si or Si1-x from being etched away in the cleaning process by a method wherein, during epitaxial regrowth of a second Si layer or a second Si1-x mixed crystal on a first Si layer or a first Si1-xGex mixed crystal layer, the surface is previously protected by SiO2 using ECR. CONSTITUTION:After the formation of an Si deposition film 15 using MBE or CVD process, when the surface is irradiated with oxygen plasma using ECR continuously in the same device to oxidize about 20-30Angstrom  in the surface into a protective oxide film 13, the active dangling bond 12 on the surface disappears so that any pollutant may not be sucked at the surface even if the thin films are brought into the atmosphere of atmospheric air or oxygen, etc. At this time, the crystallinity of a MBE film when the protective oxide film 13 is released, cleaned up and deposited again will be enhanced very rapidly. Through these procedures, the protective film 13 can be perfectly composed of minute SiO2 not to be melted into NH4OH, H2O2, H2O base or HCl, H2O2, H2O base cleaning solution thereby an Si or GexSi1-x layer as a lower layer can be prevented from being etched away in the cleaning process.

Title: Lighting system
Inventor: FUKUMOTO HIROAKI
IPC: F21V8/00
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To uniformly control the light quantity of light from the exit face of a light transmission plate to the external over the whole area and to uniformly maintain the luminance by changing the area of dots only on a part of an irregular reflection surface in accordance with the distance from a light source. SOLUTION: Light made incident from a light source 2 upon the inside of the light transmission plate 7 reaching a dot group 8 is scattered to the inside of the plate 7 and a part of light is projected from the exit face of the plate 7 to the external. When the area of only a part of dots included in the dot group 8 on the irregular reflection surface is changed in accordance with the distance from the light source 2, the areas of respective dots included in the dot group 8 can be defined so that the light quantity of light from the exit face of the plate 7 to the outside is uniformly controlled over the whole area of the exit face. Consequently generation of luminescent lines on the light source side exit face of the plate 7 can be prevented and luminance can be uniformly maintained over the whole area of the exit face of the plate 7.  Thereby unevenness is not generated on a liquid crystal screen and quality display can be obtained.
