摘要:
Various components of image-forming means such as corona discharger, developing device and cleaning means are arranged around a photosensitive drum. These processing parts and the photosensitive drum are assembled together into a unit which can be detachably mounted into the main body of image-forming apparatus. Such a unit is called process kit. The process kit is provided with a driving connection member for receiving a driving force from the main body. The present invention provides safety means for effectively protecting said driving connection member from shock and impact thereby assuring the utility of the process kit for a long time.

A process kit includes a support member having a photosensitive member integrally mounted thereon together with process elements for acting on the photosensitive member. The support member is mountable on and removable from a main image forming apparatus having an optical system for projecting an image onto the photosensitive member. The support member has a positioning element for engaging the optical system in order to position the optical system accurately with respect to the photosensitive member. This configuration permits sharply formed images to be formed on the photosensitive member after removal and remounting of the process kit.

The present invention relates to a cartridge having a liquid discharger removably mounted onto a main body of a liquid jet recording apparatus. The cartridge comprises a humidifier for humidifying a liquid discharging portion of the liquid discharger, an input member for receiving delivery of an actuating force for actuating the humidifier, an electric contact member for receiving an electric signal actuating the liquid discharger, and a box member for containing the humidifier, input member and electric member.

There is provided an image forming apparatus such as a copying apparatus having a sensor to detect the front edge of an original and a sensor to detect the front edge of a paper onto which a copy image of the original is formed, in which the copying operation is started in accordance with the result of the detections by both sensors. A distance which is obtained by adding a distance from an exposing position of a photosensitive drum and a distance from an original feed roller to an exposing position is equalized to a distance from the copy transfer position of the photosensitive drum to a paper feed roller. If such distances differ, the feeding timing of the original or paper is delayed in accordance with the difference between those distances. Thus, the cheap and small copying apparatus can be realized without using an expensive control system such as a registration roller.

A work machine includes a main pole internally including a rotation shaft, a tool unit located at one end of the main pole, and a power unit located at another end of the main pole. The main pole includes a first partial pole, a second partial pole and a joint member that joints them to each other. The first partial pole includes a positioning member. The joint member includes a positioning hole configured to engage with the positioning member and a guide groove extending from the positioning hole. The guide groove is configured to guide the positioning member to the positioning hole and to allow the positioning member to escape in at least a section thereof.

An electroconductive bonding material contains a thermosetting resin, a low-melting-point metal powder which is melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin, a high-melting-point metal powder which is not melted at a temperature equal to or lower than the thermosetting temperature of the thermosetting resin and which reacts with the low-melting-point metal powder to form a reaction product having a high melting point of 300° C. or higher during heat-hardening of the thermosetting resin, and a reducing substance which removes an oxide formed on the surface of the high-melting-point metal powder. The total content of the low-melting-point metal powder and the high-melting-point metal powder is 75% to 88% by weight, and the particle size ratio D1/D2 of the average particle size D1 of the low-melting-point metal powder to the average particle size D2 of the high-melting-point metal powder is 0.5 to 6.0. Thereby, an electroconductive bonding material is provided which has good conduction properties and high connection strength even when reflow heat treatment is repeatedly carried out or thermal shock accompanied with a rapid temperature change is applied to the electroconductive bonding material, and an electronic apparatus using such an electroconductive bonding material.
摘要:
The method of the present invention first provides a plurality of representative color points existing on the surface of a gamut (s20), and sets a plurality of boundary lines that connect the plurality of representative color points substantially along the surface of the gamut (s22). The method subsequently defines a plurality of unit faces that are respectively surrounded by at least three boundary lines and arranged substantially along the surface of the gamut (s24), and sets a color plane to cross the gamut (s26). The method successively selects cross boundary lines that cross the color plane among the plurality of boundary lines, determines intersections of the cross boundary lines and the color plane, selects unit faces that cross the color plane based on the selected cross boundary lines, specifies cross lines of the selected unit faces and the color plane by connecting the intersections, and joins the cross lines to extract a contour of a cross plane area obtained by causing the color plane to cross the gamut (s28). This structure enables the contour of a cross plane area, which is obtained by causing a color plane to cross the gamut, to be accurately extracted even when the color plane is arranged at any arbitrary position and in any arbitrary orientation.
