Title: Display device
Inventor: TORIYAMA KAZUHISA
IPC: G02F1/1343
Filed: 1986-03-07
Abstract: PURPOSE:To obtain a display device which has a large screen and a high density and is driven with high degree of time division, by forming one of stripes passing lattice intersections with a light emitting cell which emits light selectively with a stripe form and forming the other with an optical shutter cell which is switched selectively in a stripe form. CONSTITUTION:Intersections between stripe transparent electrodes 12 and 13 and stripe transparent electrodes 14 and 15 form picture elements of the display device. That is, when a sufficient voltage is impressed between an optional stripe electrode 14 of an EL cell 3 and the rear metallic electrode 15 facing this electrode 14, an EL material 18 held between these electrodes emits light with a stripe form. When a sufficient voltage is impressed between an optional stripe transparent electrode 12 and the stripe transparent electrode 13 facing this electrode 12, a liquid crystal layer held between these electrodes forms a stripe-shaped light transmission area. Thus, emitted light of the EL material 18 reaches the eye of an observer 19 through only the intersection between the tripe-shaped light emitting area of the EL cell 3 and the stripe-shaped light transmission area of the liquid crystal later. In this operation state, the crosstalk between X and Y electrodes does not exist on the structure.

Title: Low temperature baking-type organic coat-bearing rust resistant steel plate
Inventor: NAKAMURA KANJI
IPC: C23C22/00
Filed: 1992-03-05
Abstract: PURPOSE:To lessen the chromium flowing out amount and improve corrosion resistance by carrying out chromate treatment on a zinc-coated steel plate and then applying an aqueous resin emulsion containing silica and alcohol as a reducing agent in a prescribed ratio range to the plate and drying the emulsion. CONSTITUTION:After a chromate treatment liquid is applied to a zinc- or zinc- based alloy-coated steel plate, heating and drying are carried out to form a chromate coating. At that time, the deposit amount per unit area of the steel plate is limited to the range of 30-300mg/m<2>. To the coating, an aqueous resin emulsion or an aqueous resin solution (e.g. polyurethane-type resin, etc.) containing silica and alcohol as a reducing agent is applied and dried. The amount of silica in the organic coating is limited to within 5-80wt.% to improve the corrosion resistance and the addition amount of the alcohol in the aqueous resin emulsion or the aqueous resin solution is limited within 5-50wt.%. In the case the addition amount is a little, reduction of the soluble chromium is not sufficient and in the case the amount is too much, reducing reaction is saturated.

Title: Medical hybrid polymer material
Inventor: OIKAWA YUKIO
IPC: A61F2/06
Filed: 1990-02-27
Abstract: PURPOSE:To allow use as practical artificial capillary tube as well by coating an artificial material with an antibody having a self antigen oriented property to eliminate immunological response, hence providing a perfect antithrombus property. CONSTITUTION:To secure an antithrombus property, first, a layer coated with an ideotype antibody having a self antigen oriented property artificially is applied on a high polymer material. Then, an endotherium of own blood tube is transplanted on the antibody layer obtained by cultivation thereof together with serum derived from a patient. As affinity of the high polymer material to the antibody is very good, only one coating is enough. Then high polymer material herein usable is various high polymer compounds, such as silicon and polyurethane. The ideotype antibody attached to the high polymer material has no antigen-antibody reaction as biological control reaction because of a self antigen determinant it has, which eliminates thrombus even with possible proliferation of endotherium of the blood tube. Thus, one coating is enough for the antibody on the high polymer material and there is no need for previous implantation on another animal thereby reducing complication of operation.

Title: Arq transmitting system
Inventor: KUMAKURA KAZUMASA
IPC: H04L1/16
Filed: 1983-03-25
Abstract: PURPOSE:To apply an automatic retransmission request transmission system to the communication using a transmission line having a large transmission delay time by measuring the transmission delay time in a line and deciding the number of bits of a block data based on the result. CONSTITUTION:A transmission control section 11 gives a command to a delay measuring and control section 19 to actuate a delay measuring signal transmission section 17. A time (t) necessary for a delay reponse signal detecting section 18 to detect a delay response signal after the delay measuring control section 19 actuates the delay measuring signal transmission section 17 is the sum among line delay times t1, t2, a signal width t3 of the delay measuring signal and a processing time t4 at the receiving side. Since the t3, t4 are known values, the total delay time Td is obtained as Td=t-t3-t4. The delay measuring control section 19 calculates the time Td by using an equation above after measuring the time (t) and outputs the result to the transmission control section 11. The transmission control section 11 decides the number of bits (n) of block data in response to the received total delay time Td and outputs the result to a block data transmission circuit 14. Then, after the number of bits (n) is decided, a device 1 at the transmission side performs data transmission by a prescribed transmission procedure.

Abstract: PURPOSE:To obtain an accurate particle size distribution of a particle rapidly even when the refractive index thereof is unknown, by converting the intensity distribution of a diffracted/scattered light regarding one sample into a plurality of particle size distributions and by determining the smoothness of curves of these distributions quantitatively. CONSTITUTION:A laser light from a light source 1 is applied to a flow cell 2, in which a suspension 3 prepared by dispersing a group of particles to be measured in a medium liquid is made to flow in the direction perpendicular to the surface of paper. The laser light applied thereto is scattered or diffracted by the particles and an intensity distribution pattern of the diffracted/scattered light is formed spatially. In a computer 9, the condition regarding a refractive index is changed to a plurality of them by an operation on the basis of the data on the light intensity distribution taken in by A/D conversion 8 through a multiplexer 7 as to one sample, and a plurality of particle size distributions are calculated. Thereby the light intensity distribution is converted into the particle size distribution with the refractive index regarded as the most approximate to the true refractive index. The particle size distribution forming the smoothest curve is selected quantitatively from the above, and this particle size distribution is outputted as the final one to a print 10 and CRT 11 connected.
