Title: Method for mounting pellicle
Inventor: OHORI KAZUO
IPC: G03F1/64
Filed: 1990-10-16
Abstract: PURPOSE:To improve the yield of production by interposing a specific ring between a mask and a pellicle frame. CONSTITUTION:The annular cushion ring 13 consisting of, for example, silicone rubber which has elasticity and is stable to UV light is interposed between the mask 11 and the frame 12a of the pellicle 12 and the pellicle 12 is pressed to the mask 11 in tight contact therewith by a tightening means 14. The intrusion of dust, oil mists, etc., into the hermetic space enclosed by the pellicle 12 and the ring 13 is then prevented and the ring 13 deteriorated in properties by UV rays is prevented from becoming the source for dust generation. The pellicle 12 which prevents the sticking of dust to the mask 11 over a long period of time is mounted to the mask as the pellicle is formed in such a manner and, therefore, semiconductor devices are produced at the good yield.

Filed: 1986-11-25
Abstract: PURPOSE:To measure a light cutting position in an image at a high speed with high accuracy by performing statistical processing calculation for difference images between images of a body irradiated with no slit light and the body irradiated with slit light which exceed a threshold value. CONSTITUTION:An image signal outputted by a camera 41 is inputted to an image memory 3 or light cutting line extracting circuit 1 through an A/D converter 2 and the arithmetic result is outputted to a position storage memory 48. An image B obtained while no slit light is projected is inputted to the memory 3 first. Then an image A obtained while the slit light is projected is inputted to the circuit 1 and the image B is read out of the memory 3 in synchronism with said input and inputted to the circuit 1. The images A and B are inputted to a subtracter 4 and their difference signal is inputted to a subtracter 7 and compared with the threshold value. The statistical processing calculation is carried out for values exceeding the threshold value. Thus, the light cutting position in the image is measured at a high speed with high accuracy.

Abstract: PURPOSE:To form simply and stably a light-transmitting printed matter with a recorded image superior in sharpness and light-transmission, by a method wherein, a material to be recorded having an ink transfer layer and an ink holding layer is subjected to an ink jet recording, thereafter being passed through a washing process and a drying process. CONSTITUTION:In a washing process, a water content is rapidly absorbed from an ink transfer layer to wet the surface of a hydrophilic ink holding layer, whereby the ink transfer layer is easily separated from the ink holding layer. It is preferable that an interval of 15sec. and more is set after an ink jet recording is applied to a material to be recorded before the washing process and the washing process is effected within 15 minutes by water having a temperature of 35 deg.C or below. A time transmitting from the washing process to a drying process is preferably within 30 minutes. Moreover, in the drying process, it is enough that the material is dried to the extent allowing the normal handling of a light-transmitting printed matter. The drying conditions such as a drying temperature, a time, and an air quantity are not particularly limited, but by taking in consideration the softening point, melting point, decomposition point, and others of a transparent substrate, the ink holding layer, and a recording agent a drying temperature is desirably in the range from 0 deg.C to 150 deg.C under atmospheric pressure.

Abstract: PURPOSE: To prevent the defect of image quality from being caused at the time of forming a toner image in an image forming device and a two-color image forming method storing two kinds of toner having different electrostatic charging polarity and different color in one developing device and selectively transferring two kinds of toner to a latent image on an image carrier. CONSTITUTION: After uniformly electrostatically charging the image carrier 1, the latent image corresponding to the image of the 1st color is formed by a 1st latent image forming means 3, and bias voltage being the middle of the potential of the background part and the potential of an image part is impressed on the developing device 4, then the latent image is developed with two kinds of toner. The toner of the background part of the 1st latent image, whose polarity is selectively reversed based on the image of a 2nd color by a 2nd latent image forming means 5, is recovered by a toner recovery means 6 so as to form the two-color toner image. Thereafter, two kinds of toner are electrostatically charged to the same polarity by a pretransfer electrostatic charging device 7 and transferred on a recording medium by a transfer device 8.  It is conceivable that the potential of the background part of the 2nd latent image is decreased by superposing the 2nd latent image on the toner image of the 1st color and irradiating them with image light.

Abstract: PURPOSE:To obtain a modified sulfonated polyolefin porous membrane capable of permitting water to pass from a dry state by bringing the inner surfaces of the pores of a porous membrane into contact with a solution containing a water-soluble polymer and subsequently drying the porous membrane. CONSTITUTION:The inner surfaces of the pores of a porous membrane are brought into contact with an aqueous solution containing a water-soluble polymer (prepared by dissolving either one of polyvinyl pyrrolidone, polyvinyl alcohol, polyethylene glycol and dextran or a mixture thereof in a solvent having high affinity with respect to polyolefin and dissolving those water-soluble polymers such as ethanol or methanol) and subsequently dried. Whereupon, the hydrophilic water-soluble polymer is laminated to the inner surfaces of the pores of the membrane becoming hydrophilic by sulfonation and the hydrophilicity of the inner surfaces of the pores is markedly increased and the membrane capable of permitting water to pass from a dry state is obtained. Therefore, hydrophilicity imparting treatment at the time of the use of the membrane is unnecessary and it is unnecessary to enclose water in a module in order to prevent drying.
