Title: Production of color filter
Inventor: IWAMOTO MASAO
IPC: G02B5/20
Filed: 1990-11-28
Abstract: PURPOSE:To improve color characteristics and to obtain the color filters of a low cost by producing partition walls which act effectively in a stage for dyeing dyeable medium layers to pattern shapes by a black matrix. CONSTITUTION:A photosensitive resin layer 2 from which exposed parts are removed in a developing stage and a silicone rubber layer 3 and laminated in this order on a light transparent substrate 1 formed with the black matrix between previously patterned picture elements. Exposing and development processing are executed by a photolithography method with the black matrix between the picture elements as a pattern mask. Apertures are formed by removing the silicone rubber layer 3 and the photosensitive resin layer 2 in the exposed parts and thereafter, dyeable media are applied to form the dyeable medium layers 4 in the apertures. The respective dyeable medium layers 4 are dyed to three primary colors 5 to 7; red, green and blue. Namely, the partition walls to prevent 'blurring' and 'spreading' of coloring materials are formed by the black matrix. The low-cost color filters for liquid crystal display having high display quality are obtd. in this way.

Abstract: PURPOSE:To maintain a desired pressure difference between a high pressure and a low pressure while continuing an operation of a screw compressor during particularly in a pull-down operation to keep an amount of oil to be fed to the compressor and prevent its seizure. CONSTITUTION:There are provided a cold water temperature sensor 20 for a water evaporator 9, a cooling water temperature sensor 30 for a condensor 7, and a controller 60 for controlling a degree of opening of a sliding valve 4 for controlling a volume of a screw compressor 1 to a desired degree of opening (80%) in response to a cold water temperature and a cooling water temperature when the cold water temperature is less than a predetermined temperature (20 deg.C) and the cooling water temperature is lower than a specific temperature (20 deg.C) during the pull-down operation. Then, during the pull-down operation, if the cold water temperature is low and the cooling water temperature is also low, it is expected that a pressure difference between a high pressure and a low pressure is hardly set and a lack of feeding oil occurs, and a degree of opening of the sliding valve 4 is controlled from an operation of low volume to an operation of a high volume. Through this control, an increasing of discharging pressure can be promoted, a pressure difference of high and low can be kept at a desired pressure difference, a feeding amount of oil to the compressor 1 can be assured and then a seizure of the compressor 1 is prevented while continuing the pull-down operation.

IPC: G11B5/84
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To produce a magnetic recording medium at a low cost which has excellent adhesion property between the substrate and the base film even when the substrate is heated by dipping a glass substrate after reinforcing treatment in an alkali soln. having specified pH range at specified temp. range, drying and forming a base film and magnetic film on the substrate. SOLUTION: This magnetic recording medium is produced by dipping a glass substrate after reinforcing treatment in an alkali soln. of pH>=11 and pH<=14 at 40 to 60 deg.C, drying the substrate and then forming at least a base film and a magnetic film on the substrate. If pH of the soln. is <11, enough adhesion between the substrate and the base film is not obtd. A more preferable pH range is from 12 to 14. If the alkali soln. is <40 deg.C, enough adhesion between the substrate and the base film is not obtd. If the temp. exceeds 60 deg.C, it is difficult to control the surface roughness of the glass substrate to proper roughness. If the dipping time is less than 10min, enough adhesion between the substrate and the base film is not obtd.

Filed: 1993-12-24
Abstract: PURPOSE:To enhance the comfort of living environment and prevent dew formation on a front frame by forming end plates that fix two upper and lower air deflector blades into such a shape that cool air is cut off. CONSTITUTION:If end plates 3 that fix two upper and lower air deflector blades 2 are formed in such a shape that the front and rear ends of the blades 2 are connected together, cool air is cut off by the end plates 3 and a front frame is prevented from being cooled directly by cool air and from dew formation on it when the air direction is deflected by left and right deflector blades. Thereby, it becomes unnecessary to restrict the movable range of the left and right air deflector blades, and dew formation on the front frame can be prevented without spoiling the comfort of living environment.

Abstract: PROBLEM TO BE SOLVED: To reduce the necessary table size and to decrease the cache mistakes when a code word string consisting of variable length codes is decoded by referring to a code value table with the code length and a lower order bit of a code word used as inputs to output the code value. SOLUTION: When the processing is started in a step S101 and a variable length code word string is inputted, the head (n) bits are inputted in a step S102. If no escape code is decided in a step S103, a code length table is referred to in a step S104. In a step S105, the code length table outputs the code length(s) to the inputted n-bit data and the length of a code word is decided. In a step S106, (m) bits are acquired from the lower order bits, i.e., the (s-m+1)-th bit counted from the head. Then (s×2n) is offset and the code value table is referred to with the m-bit value defined as an address in a step S107. In a step S108, the code value is outputted and the decided code word is deleted from the head of the code word string.
