Abstract: PURPOSE:To reduce the unnecessary stepping as well as to contrive improvement in the preciseness of working by a method wherein a doped polysilicon layer is thickly formed, the surface of said polysilicon layer is flattened, and then an etching is performed until the required thickness of the doped polysilicon film on the part to be diffused is obtained. CONSTITUTION:A P-type impurity layer 2 is formed on the surface of an N-type semiconductor wafer 1, and a doped polysilicon layer (Dopos) 6 is grown on the surface of a silicon oxide film 3 and on the surface of the desired aperture parts 4 and 5. Subsequently, the roughened surface of the Dopos layer is flattened using a photoresist 7, and a dry etching, for example, is performed under the condition wherein the ratio of etching selectivity of the resist film and the Dopos film becomes 1, and the Dopos film located on the aperture part 4, which is the part to be diffused by Dopos, is shaved to the minimum thickness required. Besides, a CVD oxide film 8 is grown on the Dopos 6, and the unnecessary part is removed. Then, the stepping generated when the doped polysilicon is adopted as the source of diffusion is reduced using a flattening process. The uniformity of diffusion density on the surface is not impaired at all.

Inventor: YAMADA JIRO
IPC: G02F1/136
Filed: 1990-08-14
Abstract: PURPOSE:To lower the dielectric strength of a switching element without making the constitution complex by inverting a reference voltage supplied to a 2nd connection line to the opposite polarity from application to a 3rd connection line. CONSTITUTION:When one line is driven, a following (below) line is driven similarly. When the following line is driven, TFTs 57jk and 21j on the last line turn OFF. In each picture element unit 50jk, electrodes 54ajk and 54bjk and a reflecting plate form a sort of capacitor, so the applied voltage is held until a next frame is driven. After a display of a video signal of one frame (one image plane) is finished, a frame driver 23 switches the value of the reference voltage vc from 0V to 30V in a period of a next frame. Further, a source driver 25 outputs a voltage Vs corresponding to the polarity-inverted video signal. Consequently, respective picture element units are driven, line by line, as mentioned above.

IPC: G11B11/10
Filed: 1981-12-29
Abstract: PURPOSE:To reduce the writing current to accelerate the writing speed as well as to decrease the average waiting time, by providing a light transmitting part to a slider along with a condenser lens set in opposition to the light transmitting  part and then setting a writing coil at a slider part at a position where no overlap occurs in an optical path of the light transmitting part. CONSTITUTION:A slider 2 contains a light transmitting part, and a thin film magnetic head part 10 is provided to the slider 2 at a position where no overlap occurs in the optical path of the light transmitting part. When access is given to the surface of a magnetic recording medium 4 of a head 3, the slider 2 shifts to a recording track and floats above the surface 5 of the medium at a slight distance to slide there by an air current. A light beam is irradiated to the surface 5 of a magnetic layer 14 via the light transmitting part of the slider 2. Then the writing is carried out by means of a writing air core coil 10 to a magnetic layer region where the coercive force is reduced. The size of the coil 10 can be reduced since the coil is infinitely brought close to the surface of the layer 14. Furthermore, the current value is also reduced as compared with the conventional level. This process accelerates the writing speed and also decreases the average waiting time for rewriting.

Title: Immunoagglutination reagent and immunoassay method
Inventor: TANAKA SEIJI
IPC: G01N33/543
Filed: 1994-08-16
Abstract: PURPOSE:To provide an immunoagglutination reagent and an immunoassay method whereby a turbidity change due to an agglutination is observed large by a short-wave light thereby to measure amount of an antibody or an antigen with good sensitivity from agglutination amount with also hardly generating a prozone phenomenon by coagulating a liposome agglutination reagent having a covalent bond of the antigen or antibody with using liposome as a carrier through an antigen-antibody reaction. CONSTITUTION:Liposome is used as a carrier of the immunoagglutination reagent. An antibody or antigen is immobilized on the surface of the liposome. A water-soluble, low molecular compound of a higher refractive index than that of water is enclosed in the liposome. An enclosed substance increases a turbidity change resulting from an agglutination through an antigen-antibody reaction by the immunoagglutination reagent. Therefore, even if the substance in a specimen has a low concentration, the turbidity change can be measured with good sensitivity and moreover, a prozone phenomenon is hard to occur.

Title: Image forming device
Inventor: TARUMI NORIYOSHI
IPC: G03G15/05
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device constituted so that the image soiling and fogging are prevented from occurring by forming and holding the interval of such as extent that the surface of a photoreceptor can be electrified in a recording area by applying bias voltage. SOLUTION: In the recording area D, granular bodies 61 are mixed with toner on an image carrier 31. When the granular bodies 61 are brought into contact with both of the carrier 31 and the photoreceptor 2 in the area D, a prescribed interval feasible to cause electrification is formed and held. When the bias voltage is applied on a condition that the interval is formed, the surface of the photoreceptor 2 is set so that it can be electrified. Then, the surface of the photoreceptor 2 is uniformly electrified to desired polarity in the area D. Thus, the toner is prevented from being attached to a non-image part by causing a repulsive force between the toner and the non-image part. As the result, the image soiling and the fogging are prevented from occurring.
