摘要:
An original document size detection device of the present invention is characterized by comprising a document reading table, a light source which irradiates an original document placed on the document reading table, a cover body which covers the original document, a light detection unit which detects a reflected light that a light from the light source is reflected by the original document and an external light that enters the surface of the document reading table when the cover body is lifted, a masking unit which masks an output signal based on the external light in the output signal of the light detection unit based on the reflected light and the external light, and a determination unit which determines a size of the original document in a main scanning direction based on the output signal of the light detection unit that is masked by the masking unit.

A non-secure network gateway 11 and a secure network gateway 12 are individually realized as virtual machines constructed on a physical hardware unit of a real machine, and are connected, by standard protocol communication portions 20 and 25, to a non-secure network 1 and a secure network 2 using a standard protocol the standardized specifications of which have been published. Data exchange between nonstandard protocol communication portions 22 and 23 of the sub-gateways 11 and 12 is performed using a nonstandard protocol the specifications of which have not been published, and data exchange between the nonstandard side and the standard side is performed only in the application layer. Protocol conversion portions 21 and 24 refers to relay permission settings tables 30 and 31 to confirm relay permission for communication data, and perform protocol conversion only when relaying is permitted. Even in the event that illicit communication data from one network has penetrated into a gateway, penetration of the communication data into the other network can be prevented.

摘要:
An object is separately located from a touch panel in a touch panel coordinate system, and visible by a user via the touch panel. A touch position detector detects the user's touch position on the touch panel. The user's touch position is converted to a touch position in a world coordinate system using a position information of the touch position detector in the world coordinate system. A half-line connecting the touch position and a view position of the user is generated in the world coordinate system. It is decided whether the half-line crosses the object using a position information of the object in the world coordinate system.

To a fluorine-containing polymer, 0.1 to 10% of a compound comprising an alkali metal or an alkaline earth metal in terms of the number of atoms of the alkali metal or the alkaline earth metal based on the total number of the above terminal groups, 0.1 to 10% of ammonia in terms of the number of ammonia molecules based on the total number of the above terminal groups, or 0.1 to 10% of a compound having an ammonium group in terms of the number of the ammonium groups based on the total number of the above terminal groups is added, and heated at a temperature of at least 2000C in an atmosphere containing moisture. By this process, unstable terminal groups such as terminal carboxylic acid groups and coloration caused by such terminal groups are effectively removed from the fluorine-containing polymer, and furthermore unstable bonds in the backbones can be removed. The obtained fluorine-containing polymer contains 1.0×1013 spins/g or less of unpaired electrons on the carbon atoms in terms of a spin density measured with spin resonance at a temperature of 10K.

Hydrogen fluoride is effectively removed from a mixture of hydrogen fluoride, dichloromethane, chlorofluoromethane and/or difluoromethane by distilling the mixture so that two-component azeotropic mixtures of hydrogen fluoride and dichloromethane, hydrogen fluoride and chlorofluoromethane and hydrogen fluoride and difluoromethane are removed, or by liquid-separating the mixture into an upper liquid phase rich in hydrogen fluoride and a lower liquid phase not rich in hydrogen fluoride before each liquid phase is distilled as described above.

A melt-processable fluorine-containing polymer is melt kneaded with a kneader which has a residence time of at least 10 minutes, a usable volume ratio (usable space in a container/space in a container) of larger than 0.3, and a power factor K of less than 8000, the power factor K being represented by the formula: K=Pv/&mgr;/n2 in which Pv is a power requirement per unit volume (W/m3), &mgr; is a melt viscosity (Pa.s), and n is a rotation speed (rps), to effectively remove terminal groups and bonds in the backbones, which are unstable during melt kneading, from the melt-processable fluorine-containing polymer, and obtain a colorless fluorine-containing polymer.

摘要:
A polymerization process, in which when at least one of fluorine-containing olefin monomers in gaseous phase or supercritical phase or a monomer mixture of the fluorine-containing olefin monomer and other monomer copolymerizable therewith is subjected to batch polymerization in an aqueous medium while being diffused to the aqueous medium, a diffusing amount of the monomer or monomer mixture to the aqueous medium is not less than 80% of the theoretical consumption of the monomer or monomer mixture when polymerized at the theoretical polymerization rate. According to the present invention, a polymerization rate is determined by the polymerization reaction but not by the diffusion of monomer gas, and thus higher polymerization rate can be achieved.
