摘要:
An ink jet recording apparatus performing recording by discharging ink from a recording head onto a recording medium. A conveying belt for conveys the recording medium by the attraction of static electricity, an electrode contacts the recording medium conveyed by the conveying belt, and a power source charges the electrode with a charge having a polarity opposite to a charge carried by the conveying belt. The recording head includes a discharge port and a control electrode formed around the discharge port. A voltage identical to the polarity of the surface potential of the recording medium is generated by a power source and applied to the control electrode to cause the control electrode to repel any satellite droplet of the polarity identical to the voltage that splits from a discharged ink droplet during the flight thereof.

An ink jet recording apparatus performing recording by discharging ink onto a recording medium is provided with a conveying belt for conveying the recording medium by the attraction of static electricity, an electrode provided to be in contact with the recording medium conveyed by the conveying belt, and a power source capable of charging the electrode with the charge which has the polarity opposite to the charge carried by the conveying belt. The main droplet and satellite split from the ink droplet are impacted on the recording medium to prevent the adhesion of the satellite to the discharging port of the discharging surface of the recording head, thus maintaining desirable recording for a long time.

A polyurethane dispersion is obtained by aqueously dispersing an aqueous polyurethane resin obtained by reaction of an isocyanate group-terminated urethane prepolymer with a chain extender. The isocyanate group-terminated urethane prepolymer contains an adhesive urethane prepolymer for imparting adhesion and a gas-barrier urethane prepolymer for imparting gas barrier properties.

An aqueous polyurethane resin having a Si atom content of 0.05 to 1.5% by weight in a polyurethane resin is produced by at least reacting an isocyanate group-terminated prepolymer which contains 1 to 15% by weight of a polyoxyethylene group in a side chain branched from the main chain and has two or more isocyanate groups at an end of the main chain, with a chain extender which contains at least a compound having two or more active hydrogen groups reactive with the isocyanate group and an alkoxysilyl group.

A harness slack take-up structure for a steering gear enables a harness case to be compact and the harness to be a standard round harness. The harness slack take-up structure employs a movable part and a fixed part to restrict the movement of the slack of the harness somewhat and to take-up the slack, thereby minimizing the size of the harness case.
摘要:
A polyurethane resin having a total concentration of the urethane group and the urea group of not less than 15% by weight is prepared by reacting a diisocyanate component (e.g., an aromatic diisocyanate) with a diol component (e.g., a C2–8alkylene glycol). The repeating unit of the polyurethane resin may contain a constitutive unit of an aromatic or alicyclic compound. The polyurethane resin may be shaped into a film for use as a gas barrier film. The film may be a gas barrier composite film composed of a base film layer and a resin layer at least comprising the polyurethane resin. The present invention provides a polyurethane resin excellent in gas barrier properties against water vapor, oxygen, aromatics, and others, and a film containing the same.

The invention relates to a coating solution for forming transparent conductive tin oxide film, a method for producing transparent conductive tin oxide film, and transparent conductive tin oxide film. The coating solution is capable of forming, from an inexpensive starting material such as tin oxide or tin chloride, strong tin oxide film endowed with excellent conductivity and transparency. The coating solution, which is intended to be used for forming, by way of coating, transparent conductive film predominantly containing tin oxide, contains stannic acid as its major component, and a water-soluble polymer having a polar group which is dissolved in the presence of at least one compound selected from the group consisting of ammonia and water-soluble amines.
摘要:
An electronic apparatus includes a thermally insulated vessel having a cooling part therein. Disposed inside the thermally insulated vessel are a first electronic part and a second electronic part. The second electronic part is spaced apart from the cooling part while the first electronic part is in direct contact with the cooling part, such that the two electronic parts can operate at different cooling temperatures.
摘要:
A cleaning method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of detecting a recording material jam; press contacting a cleaning member to a surface of the recording material conveying belt in response to the detected jam, thus removing from the belt surface an improper discharge of recording ink; and separating the cleaning member from the surface of the conveying belt after cleaning for a period of time. The period of time is determined based upon an amount of the recording ink discharged onto the conveying belt surface.
摘要:
In a support device for a direct drive electric motor found in apparatuses such as copy machines, printers, etc., employing the method of driving a driven shaft by an output shaft of the motor in direct connection thereto, the motor body is supported by the direct connection of the output shaft of the motor with the driven shaft, and a rotation preventing plate is provided for preventing the motor body from rotating about its output shaft, as the rotation preventing plate is in engagement with a fixed member.
