Abstract: PURPOSE:To eliminate that a bird's beak is produced and to prevent an exfoliation at an interface by a method wherein an oxide film is formed in a state that the boundary part between a first polycrystalline silicon film and a metal silicide film is covered with a second polycrystalline silicon film. CONSTITUTION:A first polycrystalline silicon film 14 and a metal silicide film 15 are formed and patterned; after that, an oxide film is formed directly on their surface. At this time, the boundary part between the first polycrystalline silicon film 14 and the metal silicide film 15 is exposed to an oxidizing atmosphere, a bird's beak is produced and an exfoliation is caused at an interface. However, the boundary part is covered with a second polycrystalline silicon film 17 and an oxide film 18 is formed in a state that the part is not exposed to the oxidizing atmosphere. Thereby, it is possible to avoid such a situation. Thereby, it is possible to prevent the bird's beak from being produced and to enhance a production yield and reliability.

Title: Swelling method for tobacco stock
Inventor: OGAWA TAKASHI
IPC: A24B3/18
Filed: 1990-10-04
Abstract: PURPOSE:To enable the swelling extent of tobacco stock to be increased along with reduced shrinkage by storing for a specified period tobacco stock put to specific swelling treatment in such a state as to be <10wt.% in its moisture content and then by humidifying said stock to its standard equilibrium moisture content. CONSTITUTION:Liquefied carbon dioxide is brought into contact, in a high- pressure, low-temperature atmosphere, with tobacco stock obtained by finely chopping tobacco leaves to impregnate the tissue of tobacco leaves with this carbon dioxide followed by pressure reduction and heating to expand the carbon dioxide impregnated above, thereby swelling the tobacco stock. Thence, this stock is stored in such a state as to be <10wt.% in its moisture content for 7 days or longer. After storage, atomized water droplets are sprayed on the resulting tobacco leaves and these leaves are humidified until the moisture comes finally to its standard equilibrium value. Also, the humidification may be performed by mixing this stock with base chopped stock. Thereby, the tobacco leaves' shrinkage in the humidification will be reduced and their swell increased, and the amount of said stock to be used can also be saved.

Title: Three-phase multiplex voltage type pwm inverter
Inventor: OSAWA HIROSHI
IPC: H02P27/08
Filed: 1990-10-02
Abstract: PURPOSE:To suppress a harmonic current by slightly shifting the phases of the carriers of a plurality of three-phase inverters from each other so that the carriers cannot act as reactors to the basic wave components of the output voltages of the inverters. CONSTITUTION:The basic wave components of the output voltages of both inverters 21 and 22 are controlled to the same amplitude and same phase so that a resultant magnetomotive force can effectively act on a motor 3. In order to obtained coupling torque which acts on a harmonic component containing a side wave group of the lowest order, the phase phi of the carrier of the second inverter 22 is set at pi (rad) against the first inverter 21. The harmonic component of the first inverter 21 has the same value as that of the second inverter 22 with a different sign, because the (n) is an odd number at the second inverter 22 where the phase phi is phi=pi. Therefore, when magnetomotive forces are combined by means of a coupling reactor 1 by giving opposite polarities to the outputs of the inverters 21 and 22, a voltage drop takes place and the harmonic currents of the harmonic components are suppressed, since the magnetomotive forces are added to the harmonic components.
