An image fixing device includes an elastic roller; a back-up unit forming a fixing nip with the roller therebetween, the back-up unit including a cylindrical film, a film guide, extending inside the film, for guiding the film, and an end portion guiding member including a guiding portion for guiding an inner surface of an end portion of the film. The oil pump includes an oil pump housing formed of aluminum alloy, and an inner rotor and an outer rotor that slide along the oil pump housing with contact kept therebetween to suck and discharge oil. The methods and kits of the invention are amendable to high throughput applications for the monitoring of production and quality control of recombinant therapeutic antibodies. A second metal layer is then deposited upon the semiconductor wafer over and upon the contact plug. The parameters specific to the vender of the apparatus are set in the parameter file in advance, the IO control layer edits the parameters of the commands of a common interface and the vender specific parameters of the parameter file, converts the result into the commands of the ATM middle API, sends them to the ATM middleware, and operates the vender specific IO units.
