Abstract: PURPOSE:To obtain a high contrast ratio with intended light transmittance without decreasing considerably the light transmittance as a whole by sticking together a polarizer contg. at least two polarizing elements having different absorption wavelengths and a quarter-wave plate. CONSTITUTION:A polarizer is formed by adsorbing and orienting iodine and/or dichromatic dye as a polarizing element on a hydrophilic high polymer film then adsorbing and orienting a dichromatic dye having the absorption wavelength different from that of the polarizing element or adsorbing and orienting iodide and/or >=2 kinds of dichromatic dyes having different absorption wavelengths selected from the group of dichromatic dyes on a stretched hydrophilic high polymer film. Good contrast is obtd. if one max. absorption wavelength of the polarizing element having different absorption wavelengths has a difference on the short wavelength or long wavelength side by >=50nm than the absorption wavelength of a quarter-wave plate. Good contrast is further obtd. if designing the two polarizing elements in such a way that the max. absorption wavelengths thereof are respectively on the short wavelength side and the long wavelength side with the absorption wavelength of the quarter-wave plate as a center.

Title: Semiconductor integrated circuit device
Inventor: KAGAMI TERUYUKI
IPC: H01L21/768
Filed: 1987-03-10
Abstract: PURPOSE:To prevent a charge-up while obtaining excellent crack resistance by forming an inter-layer insulating film consisting of silica containing nitrogen at a stoichiometric ratio of 0.5-40 atmic % and a final passivation film. CONSTITUTION:Silica films containing 0.5-40 atmic % N (nitrogen) and having the same quality are each shaped to an interlayer insulating film 10 and a final passivation film 11. The silica film has no capacity blocking Na when nitrogen is included into the silica film at a value less than 0.5 atmic % to movable ions, and yield is deteriorated and crack resistance is degraded when N exceeds 40 atmic %. Consequently, the films having the same quality as properties in which no charge is stored are laminated and constituted, and there is no boundary between the films. Accordingly, a charge-up is removed even when a high-temperature bias test is executed, and blocking properties to Na and excellent crack resistance are acquired.

IPC: H01L27/10
Filed: 1987-03-11
Abstract: PURPOSE:To prevent a thermal oxide film of a part formed on the upper edge of a groove from dielectric breakdown by forming the groove formed with an upper edge with a higher surface concentration impurity diffused layer than an inner wall face on a semiconductor substrate. CONSTITUTION:An opening 4 is formed on a P-type silicon substrate 1. With a CVD-SiO2 film 3 as a mask an N type impurity, such as As, P or the like is so ion implanted to the substrate 1 as to become 1mu10<20> cm<-3> in surface concentration, and further annealed. Thus, a high concentration N-type impurity diffused layer 5 is formed. A groove 6 of the same width as that of the opening 4 is formed on the substrate 1. In this case, the diffused layer 5 remains on the upper edge of the groove 6. The films 3 and a thermal oxide film 2a are removed by RIE. Then, since the layer 5 formed on the upper edge of the groove 6 has higher concentration than that of an N-type impurity diffused layer 7 of the periphery, the thickness of a capacitor oxide film 8a by thermal oxidation is formed the same as that of a capacitor oxide film formed on the layer 7. Accordingly, the deterioration of a gate dielectric strength due to the formation of the film 8a thinner than that of the oxide film at the periphery can be eliminated.

Title: Fuel tank for vehicle
Inventor: OKAWA WATARU
IPC: B60K15/04
Filed: 1994-03-24
Abstract: PURPOSE:To make automatic fuel supply to obtain high fuel filling performance without projecting a neck of an oil fuel supplying port above a tank by extending the neck inward by a prescribed length and making a vent hole in the neck at a position corresponding to a tank-filled-liquid surface. CONSTITUTION:A neck 12 of a fuel tank 10 is extended to almost the middle of the tank 10, while a vent hole 13 is made on the upper side (of the neck 12), or at the position incorresponding to a tank-filled-liquid surface level. As the liquid surface goes up, an oil bubble produced by fuel supply tends to enter the neck 12. Howeover, when the bottom end 14 of the neck 12 is submerged beneath the liquid surface, the oil bubble is pushed out of the neck 12 by the fuel flowed out of a nozzle 16. As the liquid surface goes up further, the oil bubble enters the neck 12 through the vent hole 13, which is made in the neck 12, or at a position corresponding to the tank-filled-liquid surface level. This fact is sensed by an automatic-stop sensor 17, so that the fuel supply is automatically stopped. In other words, oil fuel supply up to almost the tank-filling-up- level can automatically be conducted without pulling up the neck 12 above the tank 10.

Abstract: PROBLEM TO BE SOLVED: To convey a hen's egg in a stable horizontal position without respect to the conveying direction and to surely release the egg in a target position. SOLUTION: This hen's egg cup is constructed of a base 16, an upper finger 1 pivoted to the base 16 by means of an upward openable pin 24, a lower finger 12 pivoted to the base 16 by means of a downward openable pin 14, and a mounting apparatus 4 which is fixed to a chain conveyor 41 so as to hold a hen's egg E in the horizontal position between the upper and lower fingers 1, 12. The upper finger 1 is fixed to the mounting apparatus 4 so as to be pivoted in its rotation center, while a cup lock 34, which is locked in the base 16 and opens the upper and lower fingers horizontally so as to turn them downward, is installed to the mounting apparatus 4. A trigger 34, by which the upper and lower fingers 1, 12 are locked so as not to be turned always excepting an egg releasing time, is arranged.  As the center of rotation is the same between the upper finger 1 and the egg E, a shift of center of gravity of the egg E can be minimized. As the upper and lower fingers 1, 12 are opened, an egg dropping position can be stabilized. In addition, the cup is formed symmetrically with respect to the axis crossing the conveying direction orthogonally, so that the egg E can be stably conveyed without respect to the conveying direction.

Title: Track-light apparatus for setting of reflecting mirror
Inventor: CHIBA MINORU
IPC: G01C1/02
Filed: 1990-03-08
Abstract: PURPOSE:To set a reflecting mirror speedily at a collimation point by projecting two flickering lights having different duty factors and the same cycle, i.e., one is not projected while the other is projected, in a manner to overlap the radiation ranges at predetermined diverging angles. CONSTITUTION:A power source 3 impresses a pulse voltage to light sources 11, 12 via a switching circuit 2, so that the light source 11 emits, for example, light of the duty factor 1/3 as shown in Fig. (A) and the light source 12 emits light of the duty factor 2/3 as in Fig. (B). A first and a second flickering lights projected from the light sources 11, 12 via the lenses have respective predeter mined diverging angles thetaA, thetaB. Optical axes A, B spreading with a slight angle phiare overlapped in the range of a small angle gamma where the collimation axis of an optical range finder is found. Accordingly, when an operator holding a reflecting mirror is within the angle gamma, a continuous light enters his or her eyes, informing the operator that he or she is in the collimation direction. On the other hand, when the flickering light enters the eyes, the operator is shifted to one side from the collimation direction.
