Title: Manufacture of reverse-conductive thyristor
Inventor: OOSAWA YUTAKA
IPC: H01L29/74
Filed: 1979-03-23
Abstract: PURPOSE:To limit the width of an isolated zone and thus to curtail cost by making the isolated zone thin in thickness or diffusing gold only to the isolated zone from both front and back when arranging a reverse-conductive thyristor from connecting a thyristor part and a diode part in reverse parallel through the isolated zone. CONSTITUTION:A p-type gate layer PB is diffused and formed on the overall surface of an n-type substrate NB to work as anode, and a p-type cathode layer PE to end at an isolated zone 12 formed later is also diffused and formed on the back thereof. Next, the isolated zone 12 penetrating the whole is provided to come at the end of the layer PE, and an n-type gate domain NE ending at the isolated zone 12 is formed in the layer PB. After that, a diode part 10 coming in contact with the isolated zone 12 is provided to come to the counter side of the domain NE, and the domain NE side is used as a thyristor part 8. A thyristor pellet 6 is thus consituted, and the isolated zone 12 is made thin in thickness through etching or Au ion is implanted thereto. According to this constitution, an erroneous ignition will not arise even from limiting the width of the isolated zone 12.

Title: Polarization-dependent loss measuring method and device
Inventor: TAKADA KAZUMASA
IPC: G01M11/02
Filed: 1994-03-04
Abstract: PURPOSE:To measure the difference of transmittance with high accuracy by feeding the light from a nonpolarizing light source to a optical wave guide to be tested, measuring the degree of polarization of the transmitted light through the optical wave guide, and determining the polarization-dependent loss based on the obtained result. CONSTITUTION:The polarized constituent of the outgoing light from an optical fiber 4 is elliptically polarized, and the rotation angles of a 1/2-wavelength plate 16 and a 1/4-wavelength plate 17 are adjusted so that the polarized constituent fed into a polarization modulator 18 is linearly polarized in the 45 deg. direction against the X-axis of the modulator 18. When the linearly polarized light is fed in the 45 deg. direction against the X-axis which is the main axis of the modulator 18, the outgoing light from the modulator 18 is not linearly polarized, thus the outgoing light from the modulator 18 is linearly polarized by a 1/4-wavelength plate 19. When voltage is applied to the modulator 18 to change the polarization direction by 90 deg., the light power transmitting a polarizer 20 is made maximum. The nonpolarizing constituent is not changed after passing through the modulator 18. The output signal from a photo-detector 21 is detected by a lock-in amplifier 22, and the voltage of the polarized constituent is obtained.

Title: Selective oxidation of silicon substrate
Inventor: OONAKA SEIJI
IPC: H01L21/762
Filed: 1980-03-19
Abstract: PURPOSE:To relieve stress concentration and prevent defect when the thick film is formed, by exercising oxidation with thick SiO2 film formed at the end of Si3N4 film which works as a mask for selective oxidation. CONSTITUTION:During oxidation of an Si substrate, SiO2 thick film is formed in proportion to 1/2 power of the oxidation time, and the speed of forming oxidation film slows down as the film gets thicker. Therefore, by oxidating on Si substrate 11 with SiO2 thick film formed at the end of Si3N4 film 14 which works as a mask for selective oxidation, stress concentration can be decreased and defect eliminated, although SiO2 film 15 formed will be thinner. Thus, leak current and noise is decreased.

Title: Production of approximate sine wave with use of rectangular wave
Inventor: SHIYOUDA EISUKE
IPC: H03B28/00
Filed: 1983-03-04
Abstract: PURPOSE:To reduce the distortions by producing an approximate sine wave through superposition of different types of single-pulse trains. CONSTITUTION:The 1st single-pulse train has the same frequency and same amplitude as a desired sine wave. The 2nd single-pulse train has the same frequency and amplitude as the distortion component which is contained in said 1st pulse train and turned into a distortion component. The 2nd pulse train undergoes inversion of polarity and is superposed on the 1st pulse train to obtain the 3rd single-pulse train. The higher harmonic component can be excluded out of the 3rd pulse train. It is possible to exclude the distortion components even for a high-order higher harmonic component by repeating the above-mentioned processes. As a result, a sine wave having a small distortion component can be obtained when an approximate sine wave is produced through superposition of pulse waveforms.
