Title: Control circuit for reversible electric-power conversion
Inventor: MAEDA KEIJI
IPC: H02M7/66
Filed: 1980-07-07
Abstract: PURPOSE:To prevent a power source from short-circuiting when thyristor circuits are changed over to each other, by performing said changeover under the condition that the ripple voltage between and the current flowing through DC buses are zero and no gate pulse exists. CONSTITUTION:A detector RVD outputs a detection signal when detecting that the ripple included in the voltage between DC buses from the detection signal obtained by a sensor VS. On the other hand, a detector ZCD outputs a detection signal when detecting that the current flowing therethrough is zero from the detection signal obtained by a sensor SH. Moreover, a detection circuit GPD generates a detection signal when detecting the absence of the gate pulse from a gate pulse generating circuit GPG. When these three detection circuits output the respective output signals, a distributor GD starts outputting either a gate signal GF or GR to selectively change over thyristor circuits THF and THR to operate. Thereby, the power source can be prevented from short-circuiting when they are changed over to each other.

CONSTITUTION:An SiO2 film 8 is formed on a single crystal Si substrate 7. The film is isolated into rectangular islands by using a photolithography technology. A polycrystalline Si film is deposited on the film. Thereafter, the film is transformed into a single crystal Si film 9 by scanning a laser beam. A mask is applied on the film and etching is performed. Thus the SOI region is isolated into several islands. Then the SiO2 film is selectively etched, and an Si microbridge 30 is formed. The bridge undergoes thermal oxidation, and the surface is coated with the SiO2 film 8 having excellent quality. Thereafter, an MOSFET, which uses the SiO2 8 as a gate oxide film 4, is formed on the microbridge 30 by using normal processes.

Title: Atmospheric ionization mass spectrometry and device
Inventor: NAKANO KAZUO
IPC: H01J49/04
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To detect and quantitatively determine NOx(nitrogen oxides) in air at high sensitivity. SOLUTION: In this mass spectrometry, Ar(argon) gas 1 for generating primary ions is introduced into an ion generating part 15 and ionized using a needle electrode 19 to produce primary ions which do not contain NOx. The primary ions are introduced into a mixing part 30, together with the primary ion generating gas, and mixed with dry air serving as sample gas 2. At the mixing part 30 the dry air is ionized through an ion-molecule reaction using the primary ions. The sample gas 2 ionized is introduced into a mass spectrometry part 11 and analyzed.  Thus even if NOx are produced by the ionization of O2 and N2 in air components during the ion analysis of NOx contained in the air, the generation of NOx can be prevented by supplying the previously generated primary ions to the mixing part and ionizing the air, whereby trace amounts of NOx contained in the air can be analyzed at high sensitivity.

Filed: 1979-07-23
Abstract: PURPOSE: To successively perform the conveying operation of a sheet optionally from the uppermost sheet or from the lowermost sheet, by sloping a mounting platform toward a feed roller.  
     CONSTITUTION: A selection for the conveying operation whether to start from the uppermost position of draft papers or the lowermost position is performed by the shifting motion of a knob 52. When the knob 52 is shifted to a position as shown in the drawing, rollers 73W75 are shifted in the case of a mounting platform 8 to lift mounted draft papers 9 upward. This causes the end of the mounted draft papers to be diagonally stripped off by a separating roller 25 located at the lower side of the passage, permitting the conveying operation of the mounted draft papers 9 sheet by sheet successively from the uppermost position by a feed roller 24 at the upper side. When the conveying operation is started from the lowermost draft paper, the knob 52 is shifted downward to move the rollers 73W75 to the outside of the mounting platform 8 and allow the mounting platform 8 to make a turning motion about a shaft 70 counter clockwise.
