摘要:
The present invention relates to a method for manufacturing a sintered bearing having a bearing surface that forms a bearing gap with a shaft to be supported, in its inner periphery. This manufacturing method includes: a compacting step P2 of compacting a base powder containing a diffusion alloyed powder 11 prepared by partially diffusing a copper powder in an iron powder as a main material, a low-melting-point metal powder 14, and a solid lubricant to obtain a green compact, and a sintering step P3 of sintering the green compact 4′ to obtain a sintered compact 4″.
摘要:
Provided is a sintered bearing (1) including an inner layer (2) and an outer layer (3) formed by integral molding, the sintered bearing (1) having a bearing surface (A) formed on an inner peripheral surface (2a) of an inner layer (2). The inner layer (2) is made of sintered metal containing Fe and a hardness increasing element (such as Ni or Mo). The outer layer (3) is made of sintered metal containing Fe and no hardness increasing element. A concentration gradient of the hardness increasing element is present at an interface between the inner layer (2) and the outer layer (3).

There is provided a sintered bearing having high rotational accuracy and low rotational fluctuation. This bearing includes a bearing surface (4a), and is made of a sintered compact (4″) produced by molding and sintering a raw material powder (10) containing a partially diffusion-alloyed powder (11) in which a copper powder (13) is partially diffused on a surface of an iron powder (12), a tin powder (14) as a low-melting-point metal powder, and a graphite powder as a solid lubricant powder. The sintered bearing has a radial crushing strength greater than or equal to 300 MPa.

A PC 1 recognizes a connection of the multipurpose machine 3 to the network 4, and a first driver, which corresponds to information equipment provided by the recognized device, is installed on the PC 1. The PC 1 acquires a supplement installer that installs a second driver, which enables the functions of the device to be used, on the PC 1 from the IHV Web server 100 upon installation of the first driver on the PC 1. Then, the supplement installer determines whether or not the second driver needs to be installed on the PC 1. When the second driver needs to be installed on the PC 1, the second driver is installed on the PC 1.

A data processing apparatus includes a storage unit that stores print history data, and a display unit that displays a screen for introducing recommended software based on the print history data.
摘要:
The installation of multiple applications by an installer is executed in a mode that does not display an error message in a display device. Upon an installation performed by the installer ending, the result of the installation performed by the installer is determined. As a result of the determination, an installer that failed at the installation is caused to re-execute the installation of the application whose installation failed in a mode that displays an error message in the display device. As a result of the re-execution, an error message is displayed in the display device by the installer that failed at the installation.
