Patent JP-H0245963-A (JP)
Title: Semiconductor device
Inventor: WATABE KIYOTAKA
IPC: H01L23/20
Filed: 1988-08-06
Abstract: PURPOSE:To keep a dangling bond from being formed and prevent the deterioration of electric characteristics by sealing a hydrogen gas into a closed space in which a semiconductor element is installed. CONSTITUTION:A semiconductor element 1 is sealed in such a way that it is surrounded to an airtight state by means of an enclosure 4 as a sealing member. A recessed part in the enclosure 4 functions as a hermetically sealed space which is sealed by the enclosure and a hydrogen gas is sealed into the recessed part in order to protect the element 1 from corrosion. Even if a dangling bond is formed at the interface of an insulating film in the element 1 by irradiating X-rays, hydrogen atoms are supplied from the sealed space and then, the hydrogen atoms extinguish the dangling bond after terminating it. The supply of the hydrogen gas thus keeps the dangling bond from being formed and the deterioration of electric characteristics are prevented.

Abstract: PURPOSE:To minimize wear of a carbon rolling body even under heavy-load condition so as to increase its service life by providing the carbon rolling body with a carbon density of 1.55g/cm<3> or more and a hardness higher than that of metal races. CONSTITUTION:A ball 3 provided between an inner and outer metal races 1 and 2 has a carbon density of 1.55g/cm<3> or more and has a hardness higher than that of the inner and outer metal races 1 and 2. This prevents non- lubricated status which may be caused by worn out solid lubricating agent and minimizes friction of the ball 3, thus extending the service life.

Title: In-tunnel lighting system
Inventor: KINOSHITA KAZUO
IPC: F21S9/02
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To illuminate a predetermined area, as determined from the entrance of a tunnel, with brightness proportional to that immediately in front of the tunnel entrance during the daytime, by installing a main illumination along almost the entire length of the tunnel and an auxiliary illumination at both end portion of the tunnel. SOLUTION: At night, only a main illumination 3 with a commercial power supply is turned on, while an auxiliary illumination 5 powered by a solar battery is not. As the sun rises in the morning, a solar-battery module 6 starts generating power according to the brightness of the sun, and the auxiliary illumination 5 powered by it is turned on. When it is fine, the auxiliary illumination 5 operates at rated power, supplying sufficient brightness into a tunnel 1. When it is cloudy, the solar light decreases, and the output of the module 6 and hence the illuminance of the auxiliary illumination 5 decrease accordingly, but since it is dark outside, sufficient illuminance is maintained for humans passing through the tunnel to adapt their eyes to the brightness inside. Also when the rainy or cloudy weather has improved abruptly, the output of the module 6 is instantaneously restored.

Title: El panel light emission and el light emitting display device
Inventor: KANDA MINORU
IPC: H05B33/06
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To give a brightness contrast easily between a pattern and a background, or pattern components by layering a plurality of light emitting parts which is independent of each other on a common back surface electrode, and applying voltage between the respective light emitting parts. SOLUTION: Negligence of the effect of the impedance of a wiring and a capacitor would bring about a state where two capacitors whose electrode-to- electrode spacing is even are connected in series, therefore, the total value of voltages V1 , V2 for generating the electric fields E1 , E2 of the respective capacitors meet applied voltage V. The areas of regions 4a, 4b are taken as S1 , S2 , and average dielectric constants between the regions 4a, 4b and back surface electrodes 1 are taken as ε1 , ε2 respectively, a ratio of E1 to E2 follows E1 :E2 =ε2 S2 :ε1 S1 . Therefore, if the dielectric constants ε1 , ε2 are even to each other, the electric field is inversely proportional to the areas S1 , S2 of the regions 4a, 4b, by which brightness contrast which meets the inverse number of an area ratio is generated, so that the portion of a small area emits brighter light.

Title: Battery
Inventor: FUJIMOTO MASAHISA
IPC: H01M10/05
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To improve the mobility of ions in a low-temperature atmosphere and provide a sufficient battery capacity even in the low temperature atmosphere, by providing a magnetic-field generating means for generating a magnetic field normal to a flow of ions between a positive electrode and a negative electrode. SOLUTION: When a battery is made, a battery can 4 is used having a magnet 4a of samarium cobalt with a remanence intensity of 260 kJ/m3 attached to its bottom part so that the S pole contacts with the battery can 4. A positive- electrode lid 6 is used having a magnet 6a of samarium cobalt with a remanence intensity of 260 kJ/m3 attached to its upper surface so that the N pole contacts with the positive-electrode lid 6. Because the magnets 4a, 6a, as magnetic-field generating means, generate a magnetic field oriented differently from a flow of ions between a positive electrode and a negative electrode, Lorentz's force is exerted on the ions by the action of the magnetic field when they move between the positive electrode and the negative electrode. Therefore, the temperatures of electrolyte, etc., are raised, and battery characteristics in a low-temperature atmosphere can be improved.
