Title: Manufacture of semiconductor device
Inventor: TAKAHASHI MINORU
IPC: H01L21/268
Filed: 1987-01-14
Abstract: PURPOSE:To prevent the generation of a bird's beak by forming a recessed groove in an element forming region on the surface of an insulating film deposited on a substrate and by forming the single crystal semiconductor element forming region deposited on the insulating film thicker than the other region. CONSTITUTION:After an SiO2 film 12 on which a groove 13 is formed is formed on a single crystal Si substrate 11 and a polycrystalline Si film 14 is formed on the SiO2 film 12, the film 14 is melted by irradiating an electron beam and recrystallized and a single crystal Si film 14' is formed. In this case, the Si film near an element forming region flows over the groove 13 and the thickness of the film 14' in the element forming region is made thicker. Then, an Si3N4 film 17 is formed in the element forming region and a field oxide film 18 is formed by oxidizing the film 14' using the film 17 as a mask. In this case, a bird's beak is not extended to the element forming region since the thickness of the single crystal Si film except the element forming region where the film 18 is to be formed is thinner. Then, the film 17 is removed and a gate oxide film 19, a gate electrode 20, a source region 21, a drain region 22, an Al wiring 24, etc., are formed.

Abstract: PURPOSE:To attain remarkable man-hour reduction and cost reduction by forming an ''Invar'' flat bar into round shape, forming a round pipe by seam welding and drawing this round pipe so as to form a rectangular waveguide. CONSTITUTION:First the ''Invar'' flat bar 1 is formed into round shape, the seams 3 are welded to form the ''Invar'' welded round pipe 2.

Then, the flat trigger is passed into a roller die of parallel rolls and the trigger is drawn by a chain type drawing machine. In taking the pitch of the parallel rolls as a larger size than a short side of the final rectangular shape slightly in this case, an intermediate square pipe 4 having a slightly larger diameter than that of the final rectangular pipe is formed. The residual stress is eliminated by applying heat treatment to the intermediate square pipe 4, a lubricant is coated, then drawing is executed by a conventional drawing machine. Thus, the ''Invar'' rectangular waveguide 5 is obtained. Remarkable man-hour and cost reduction are attained by this method.

Title: Inverter unit
Inventor: ONISHI MASAHITO

Filed: 1990-01-13
Abstract: PURPOSE:To enable high speed switching of switching element by connecting a series circuit of a third switching element having smaller capacity than a first switching element and a voltage detecting element in parallel with the first switching element, and performing ON/OFF control of the third switching element. CONSTITUTION:Upon falling of output V from an oscillation circuit 2, outputs Vc2, Vc3 from drive circuits 42, 43 also fall down and switching elements SW2, SW3 are turned OFF approximately simultaneously. Since the capacitive component Cs3 of the switching element SW3 is considerably smaller than that Cs2 of the switching element SW2, the capacitive component Cs3 is quickly charged with a charging current fed from a load current 5 through a diode D1 and a charging current fed from a power supply E1 through a resistor R1, and the potential V1 at the input terminal of a drive circuit 41 rises instantaneously. Consequently, switching operation is carried out with high speed.

IPC: G21C3/62
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To enable use as a nuclear fuel of a light water reactor and a heavy water reactor, by performing at least a kind of coating of oxide, carbon, carbide and metal on the surface of nitride nuclear fuel particles. SOLUTION: Particles 1 containing nitride nuclear fuel are prevented from direct contact with water even if water enters by covering the surface of the particles 1 containing the nitride nuclear fuel with non-permeable coating 2. With regard to the coating, an oxide film formed by moderately reacting the nitride nuclear fuel particles at a temperature not exceeding 100 deg.C is used. In addition, oxide such as aluminum oxide, a carbon film such as graphite, a carbide film such as SiC or a metal film may be coated on the surface of the nitride nuclear fuel particles to form the film. As a result, in the case where nitride such as uranium nitride and plutonium nitride is used as nuclear fuel of a light water reactor or a heavy water reactor, contact with water can be avoided in an accident.  As a result, the difficult problem of the nitride nuclear fuel can be avoided, high heat transfer and high nuclear fuel density having the nitride nuclear fuel are utilized, and operation in lower fuel temperature is enabled.

Abstract: PURPOSE:To prevent the warpage of the optical waveguide circuit board by providing the rear surface of the substrate of the optical waveguide circuit with a stress imparting film having a thermal conductivity. CONSTITUTION:A lower clad glass layer is deposited on a silicon substrate 1 and in succession, an optical waveguide (core glass) layer is deposited thereon. The substrate is then heated at a high temp. to vitrify the optical waveguide (core) glass layer to transparent glass and the unnecessary part of the optical waveguide (core) glass layer is removed to form the optical waveguide (core) 4. An upper clad glass layer is then deposited on the optical waveguide (core) 4 to embed the optical waveguide (core) 4. These layers are thereafter subjected heating and cooling, by which the optical waveguide is produced. The substrate 1 is warped to a projecting shape in this state by the thermal stress of the silicon substrate 1 and the quartz glass of the optical waveguide (core) glass layer. An amorphous silicon film 7 of a suitable film thickness is thereafter deposited over the entire rear surface of the silicon substrate 1, by which the thermal stress of the clad glass layer 6 is compensated and the warpage of the silicon substrate 1 is eliminated.
