Title: Pogo suppressing device for liquid fuel rocket
Inventor: SHIRAI YUJIRO
IPC: B64G1/00
Filed: 1990-04-04
Abstract: PURPOSE:To surely suppress POGO oscillations (cyclic oscillations parallel to the center line of the vehicle) by providing an accumulator giving compliance, an orifice giving resistance, a gas feeding device feeding gas to the accumulator, and an opening adjusting device adjusting the opening of the orifice. CONSTITUTION:An accumulator 1 is fitted to a feed line 6, gas is contained inside to give compliance, and a POGO suppressing action is exerted by the compliance and resistance given by an orifice 2. A gas feeding device 4 and an orifice diameter adjusting device 5 are provided to adjust the compliance and resistance. POGO oscillations occur in conjunction with the oscillation mode of an airframe, thus an acceleration gauge 3 is fitted to the airframe, when pulsations (or oscillations) occur, the acceleration gauge 3 monitors which oscillation mode is in use, and the compliance and resistance are adjusted by the signal to the values to suppress POGO oscillations.

Title: Cart for visual inspection device inside reactor container of tokamak nuclear fusion reactor
Inventor: TAKAHASHI KENJI
IPC: G21B1/25
Filed: 1993-04-15
Abstract: PURPOSE:To enable the movement and inspection inside a reactor container in the condition where no pressure is applied on the wall of a vacuum and high-temperature reactor container, make a cart smaller by folding it and facilitate the insertion from a narrow entrance into a reactor container. CONSTITUTION:Induced current is generated in a coil 8 of a cart 4 for a visual inspection device which has come near poloidal coils 2 by applying high frequency current of the same electric potential to an inside pair of poloidal coils 2 and an outside pair of them respectively in the opposite directions to generate an alternate magnetic field between these poloidal coils 2. Then, while the cart 4 for a visual inspection device is floated by generating repulsion through the interaction between the induced current and the magnetic field generated in the poloidal coils 2, three-phase alternating current is applied one by one to each toroidal coil 3 to generate a progressive-wave magnetic field between toroidal coils 3 and move the cart 4 for a visual inspection device circumferentially. When the cart 4 for a visual inspection device is not floating but at a standstill, the inside of a reactor container is inspected by a remotely controlled camera 5.

IPC: B41M5/30
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the curling of a film by adding at least one of a cured resin and an uncured resin to a thermal color forming layer. SOLUTION: As a cured resin material, one generating polymerization reaction by the irradiation with ultraviolet rays or electron beam or heat and cured to become a resin is used. A non-curable resin is a resin having a hydroxyl group or a carboxyl group in its molecule. A thermal recording layer is obtained by coating a support with a dispersion or soln. prepared by uniformly dispersing or dissolving a color former, a coupler and a curable resin in an org. solvent and drying the coated support and contains an uncured resin even after drying. If necessary, the uncured resin is cured by the irradiation with ultraviolet rays or electron beam. By this constitution, the curling of a base film can be markedly reduced.

Filed: 1984-05-04
Abstract: PURPOSE:To derive exactly a line width of a pattern by measuring an emission angle of a light projected to the pattern before and after the working by using a prism. CONSTITUTION:A film 1 of a refractive index n1 and a thickness (t) is placed between a substance 2 of a refractive index n2 and a substance (for instance, air and a liquid) of a refractive index n0, and a light 5 of a wavelength lambda is wave-guided by an m-order mode into the film through a prism 4 of a refractive index np' stuck closely and placed on the film 1.

Title: Back type dc-dc converter circuit
IPC: H02M3/155
Filed: 1992-03-13
Abstract: PURPOSE:To improve efficiency and lower noises by connecting a first capacitor in parallel with a flywheel diode and connecting a third capacitor and a second diode in the reverse direction in parallel with a main switching element. CONSTITUTION:A capacitor C1 is connected in parallel with a flywheel D2, and a parasitic capacitor Coss and a parasitic diode D1 are connected to a main switching element Q1. When the main switching element Q1 is interrupted, the parasitic capacitor Coss is charged by currents IL1 while the capacitor C1 is discharged. Voltage between the drain-source of the main switching element Q1 is increased gradually, and switching loss is reduced in the main switching element Q1. When the voltage Vc1 of the capacitor C1 reaches DC voltage V1, currents IL1 flowing through a choke coil L1 through the parasitic diode D1 and a DC power supply V1 are regenerated. Accordingly, the zero voltage switching of the main switching element Q1 is enabled.

Title: Manufacture of lead wire for tubular bulb
Inventor: TAKAHASHI KUNIO
IPC: H01J9/28
Filed: 1979-07-17
Abstract: PURPOSE:To make the grain boundary of a plated layer smaller and eliminate the generation of impure gas and the disconnection of wire in early period by performing a plating process prior to the final wire drawing process in the manufacture of a lead-in wire plated with nickel. CONSTITUTION:An iron or copper core wire, subjected to a drawing process where the core wire is drawn to a diameter of 0.85mm., is deoiled by trichloroethylene, lustred, washed with an acid, neutralized, washed with water, and then plated with nickel in a thickness of 1.0-1.5mu. Afterwards, the wire is drawn down to a diameter of 0.5mm., deoiled by trichloroethylene, and then annealed at 700 deg.C for 1hr to obtain a lead-in wire. Thus, because the dendrite-textured crystals of the plated layer are broken by the final drawing process and the grain boundary is made smaller due to the coarsening of the crystals by the subsequent annealing process, the generation of impure gas and the presence of oxides can be suppressed and a tubular bulb of better characteristics can therefore be obtained.
