Abstract:
PURPOSE:To improve the accuracy of the thickness of patterned enzyme immobilized films by using patterned porous hydrophilic films having a uniform thickness. CONSTITUTION:An enzyme-contg. soln. injected from an ink jet nozzle 3a adheres onto the patterned porous hydrophilic films 2 and penetrates into the films. The enzyme liquid is held in the films 2 by surface tension and is nearly uniformly spread therein. The enzyme is uniformly distributed in the films even after drying. The patterned enzyme immobilized films having the uniform thickness are, therefore, obtd. by using the patterned porous hydrophilic films. Dropping of the enzyme to a prescribed sensor region is permitted by placing a wafer 1 on an X-Y stage and moving the position thereof with good accuracy. The formation of the enzyme immobilized films having the uniform characteristics on the wafer is permitted by controlling the dropping rate of the enzyme liquid.
Abstract:
PURPOSE:To form a biosensor having several kinds of enzyme immobilized films, by a method wherein an enzyme immobilized film and a photoresist layer are formed on a substrate provided with an ion sensor and a process of removing all but a portion required therefor. CONSTITUTION:An ion induction section 2 of an FE type ion sensor is provided on the top surface of a substrate 1 and an enzyme immobilized film 3 and a photoresist layer 4a are formed over the entire surface thereof. Then, the photoresist layer 4a is removed except for a specified surface of the ion induction section 2a by exposure and development and the enzyme immobilized film 3 is decomposed. Thereafter, a second enzyme immobilized film 5 and a photoresist layer 4b are formed on the top surface of the ion induction section and the same removing process is repeated to form a biosensor having different enzyme immobilized films 3 and 5 on the ion induction section 2. Thus, a massproducible fine multi-biosensor can be obtained by applying an IC production technology.
Abstract:
PURPOSE:To integrate ion sensors so as to measure difference ions simultaneously by forming the island-like ion sensor part on a sapphire substrate and extending a substrate earth area, a source area and a drain area from a silicone area of the sensor part independently each other to connect them to respective electrodes. CONSTITUTION:An island silicone substrate layer 2 is formed on the sapphire substrate 1. A source area 3 and a drain area 4 both of which consists of high impurity concentration areas having conductivity different from that of the layer 2 and a substrate earth area 7 consisting of a high impurity concentration area having the same conductivity as that of the layer 2 are formed on the substrate 2 independently. The layer 2 between the areas 3 and 4 is covered with an ion sensitive film 6 to form an island-like ion sensor part. The areas 3, 4, 7 are extended on the substrate 1 independently each other and a source electrode 8, a drain electrode 9 and an earth electrode 10 are formed by ohmic contact with respective metals. Thus, the necessary number of ion sensors obtained by forming ion sensitive films having difference characteristics corresponding to different ions respectively are integrated so that different ions in a solution can be measured simultaneously.

PROBLEM TO BE SOLVED: To provide a glass-typed image displaying device that can display a large and bright image and make it smaller and lighter. SOLUTION: The image displaying device installs an optical scanner 5 and an object lens 4 made from a silicon-made movable mirror in one of a temple 9 of glasses, and a prism 3 refracting light, an eyeglass 2 and a cubic beam splitter 1 in the front of the glasses. It promotes the incidence of an optical beam scanned obliquely from the optical scanner 5 into a pupil 7 of an eyeball 6, whereby an image connecting focal points on retina 8 is displayed. An adjusting part changing the interval of two cubic beam splitter 1 can lead the optical beam to both eyes, respectively, thus providing the visible image displaying device and the large image can be seen by making the focal length of the object lens 4 larger than that of the eyeglass 2.

Abstract:
PURPOSE:To reduce the consumption power for heating a cathode in operation and for discharging the adsorbed gas extensively, by processing thin the part corresponding to the electron discharging part of a cold cathode substrate, and feeding a current to the thin part, 70 as to heat locally. CONSTITUTION:To the opening of a gate electrode 4, and the rear side of an electron discharging part where minute cold cathodes composed of emitters 3 with tips formed sharp are gathered, in a substrate 1, a recess or an electron discharge substrate 5 is formed by an etching or the like. Since the substrate 5 is thin enough, the heat is generated by letting flow a current between an electrode A 6-1 and an electrode B 6-2. The heat is generated at the part very close to the heating part in operation. In a normal processing course of a vacuum device, the gas adsorbed to the parts in a container is exhausted by heating, and in this case, maintaining the electron discharge part which gives a strong influence to the electron discharge property at a high temperature locally is effective extremely to maintain a high vacuum and the discharge property.
