Title: Photocatalytic body, its production, deodorization device and lighting fixture
Inventor: SAITO AKIKO
IPC: H01J61/35
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a photocatalytic body in which capacities of both deodorization and stain resistance are excellent and to provide a method for producing the photocatalytic body, a deodorization device and lighting fittings. SOLUTION: Photocatalytic films 2, in which surface roughness is <=20 nm, favorably 0.1-10 nm in centerline average roughness Ra, are formed on the surface of a substrate 1. Anatase-type titanium dioxide is formed into the photocatalytic films 2. Substance such as glass, ceramics, pottery, stone, metal and wood may be used for the substrate. In the case of producing the photocatalytic films 2, for example, dispersion liquid of fine grains of photocatalytic substance, in which primary grain size is 1-100 nm, and secondary grain size is <=1000 nm, is prepared. Dispersion liquid is applied to the surface of the substrate, dried and thereafter burned and bound to the substrate. In the obtained photocatalytic films 2, an uneven surface state is obtained by fineness in texture of fine grains of the photocatalytic substance and accordingly surface area is made very large.  Therefor, smelly gas molecules pass through the pores of the photocatalytic films and enter the inside and are rapidly decomposed. Since particles 3 of contaminant are large and do not pass through the pores, contaminant is brought into contact with the surfaces of the photocatalytic films 2 and decomposed.

Title: Variable time constant type nutation damper
Inventor: KITADE KENJI
IPC: B64G1/38
Filed: 1993-11-15
Abstract: PURPOSE:To provide a variable time constant type nutation damper in which a nutation damping time constant is changeable on a track, and power consumption and the occurrence of the magnetic field are little. CONSTITUTION:Electric viscous fluid 2 to show viscosity corresponding to given electric field is enclosed in the pipe of an annular damper container 1. Two mutually insulated electrodes 3, 4 are arranged at opposite positions in the pipe of the damper container 1, and variable voltage E is applied from a control section 5 between the electrodes 3, 4. In this case, the electric field is given to the electric viscous fluid 2, but since the viscosity of the electric viscous fluid 2 alters in proportion to the square of the magnitude of the electric field, the nutation clamping time constant of the variable time constant type nutation damper alters in proportion to the square of the voltage E.

Title: Manufacture of oxide superconductive wire material
Inventor: KUMASAKA KENICHI
IPC: B28B1/00
Filed: 1988-11-11
Abstract: PURPOSE:To increase the orientation property of superconductive ceramic crystals and improve the critical current density by filling powders or fused matter of oxide superconductive material in a pipe for a sheath material while applying an electric field or magnetic flux or both of them to the filling. CONSTITUTION:In filling powders 2 or fused matter of superconductive material in a pipe 1 for a metal sheath material, a current 5 or a magnetic field 6 is applied, or both of them are applied. The grains 2 or fused matter of the superconductive material are arranged in a direction in which the current 5 is more likely to flow, or which makes the magnetic flux 6 more stable. This means that the grains oriented and arranged to the C-axis or a-, b-axis of the crystals are obtained. The critical current density can thus be increased.

Title: Rapid cooling device in continuous annealing furnace
Inventor: NAKAYAMA ICHIRO
IPC: C21D9/56
Filed: 1990-10-23
Abstract: PURPOSE:To prevent the development of explosion and to stably execute forced cooling by making inert gas low temp. with a heat exchanger, feeding under pressure, injecting to a strip, detecting oxygen concn. in a furnace and executing introduction of the inert gas and shut-off of atmosphere. CONSTITUTION:The inert gas is made to the low temp. with the heat exchanger 18 arranged in an atmospheric box 16 and the pressure thereof is made to high with the gas pressure feeding device 14 and the gas is fed to a gas injecting device 17 and injected to the strip 7, and is forcedly cooled. The mixing of atmospheric gas from adjoining zone is prevented with the shut-off device 10 for furnace atmosphere at front and rear parts of cooling zone 3. In the case the oxygen invades into the cooling zone 3, this is detected with an oxygen detector 13. By this detected signal, the inert gas is immediately introduced into the cooling zone 3 from an inert purge gas injecting device and the oxygen concn. is lowered to the explosion point or lower. Further, partition function of the shut-off device 10 for furnace atmosphere is strengthened. As the strip 7 restrains shifting with a shifting restraint control device 19, the strip 7 is rapidly cooled while passing the strip at high velocity without hitting the strip to the gas injecting device 17, etc.

Title: Power supply
Inventor: SUZUKI HIROSHI
IPC: H05B41/24
Filed: 1992-10-22
Abstract: PURPOSE:To provide a downsized low cast power supply having simple structure in which higher harmonic components in input current can be reduced together with noises. CONSTITUTION:Energy discharged from a first resonance circuit 13 connected with an inverter circuit 5 resonates with a second resonance circuit 12 to raise the voltage. When energy is fed from a second capacitor C12 to the inverter circuit 5, voltage level of the second capacitor C12 drops and deficiency of energy is supplemented from a first capacitor C11 when the voltage level of the second capacitor C12 drops below the voltage level of the first capacitor C11. Upon discharging energy, the second capacitor C12 is charged by a third capacitor C13. Since charging current containing much third harmonic is not fed from an AC commercial power supply E through a full-wave rectifier circuit 2 but a current is fed from the AC commercial power supply E through a second resonance circuit 12 at all times, the inverter circuit 5 can be fed with an input current containing less third harmonic at high power factor.

Title: Take-up control device
Inventor: FUKUDA YOSHITOMO
IPC: B65H67/04
Filed: 1986-11-28
Abstract: PURPOSE:To eliminate a shock by applying the deceleration pattern of the predetermined deceleration rate to a speed control criterion and taking, for example, the time integral of a difference between the predetermined speed and a winding speed so that a time until reaching the predetermined time is equal to an excessive speed time against the predetermined speed. CONSTITUTION:The material speed Ws of a strip-shaped material 1 is constant and a take-up device 2 starts after the leading end of the material 1 is caught in a clip 3. Therefore, slackening occurs until a point T1 when the winding speed Ls of the take-up device 2 rises up to the material speed Ws. This slackening corresponds to the time integral S1 of (Ws-Ls). Also, when the take-up speed Ls has entered an excessive speed operation with the winding speed Ls exceeding the material speed Ws, the slackening beings to disappear and after a certain time (time T3), the slackening becomes zero. However, the winding speed Ls is reduced before the timing T3. Speed reduction timing T2 therefor is so taken that the time integral S2 of (Ls-Ws) from T2-T3 will be equal to said time integral S1, thereby establishing the relationship of Ls=Ws at the time of slackening disappearance.
