A method to update firmware in a plurality of peripheral devices and a computer using the method to reduce data transmission collisions and to reduce the time required to complete the update process. The process involves sending firmware update data from a computer that is connected to a communication network to printers or other peripheral devices that are also connected to the communication network. The computer 11 groups a plurality of peripheral devices (such as printers 13a1) connected to the communication network into separate transmission unit groups each containing up to a maximum number of peripheral devices. The maximum number may be a predefined number or a number set according to the transmission speed of the network. The update data for updating the firmware is transmitted to the peripheral devices of any one transmission unit group. Thereafter update data is sequentially transmitted to the peripheral devices in another transmission unit group but not until the completion of transmitting the update data to all of the peripheral devices in the first transmission unit group is confirmed.

A blower includes a fan that has blades and generates an air flow by rotating. Each of the blades has a front edge and a serration provided at least in a part of the front edge. The serration has tip portions and recessed portions arranged alternately with each other. Each of the blades has a negative pressure surface and one or more ribs protruding from the negative pressure surface. Each of the ribs extends from a corresponding one of the recessed portions, which is designated as a starting point, toward a rear edge of a corresponding one of the blades.

The present application provides a linear actuator which uses a magnetic drive mechanism to drive a movable element and which can effectively suppress resonance of the movable element even when a spring member is connected thereto. Specifically, this linear actuator (1) is provided with: a stator (2), a movable element (6), a spring member (8) connected to the movable element (6) and the stator (2), and a magnetic drive mechanism (5) which drives the movable element (6) along an axis (L). Further, between the stator (2) and the movable element (6), gel-like damper members (9) that comprise silicone gel, etc., are arranged in positions on the axis (L) and/or positions surrounding the axis (L). For example, in the stator (2), the gel-like damper members (9) may be arranged in positions along the axis (L) between the movable element (6) and a base (4) opposite the movable element (6). The gel-like damper members (9) include a first gel-like damper member (91) positioned on the axis (L), and second gel-like damper members (92) positioned so as to surround the axis (L).

A centrifugal-pendulum vibration absorbing device, including a member attached coaxially with a rotary element; and mass bodies swingably coupled to the support member and disposed adjacent to each other in a circumferential direction. The mass bodies are configured such that when a first mass body, which is one of two mass bodies disposed adjacent to each other, and a second mass body, which is the other of the two mass bodies, move with respect to the support member so as to approach each other, the first mass body and the second mass body overlap each other as seen from an axial direction of the rotary element.

Embodiments of the invention suppress collision between a head element section and a magnetic disk. In manufacturing a hard disk drive (HDD) according to an embodiment of the present invention, recession R is preliminarily measured for each head slider. Recession R means the amount of recession of the head element section relative to the slider. Write current and heater current values respectively for the write device and the TFC heater are registered based on the measured recession. Since these values are set according to the recession of the head element section, it is possible to prevent each head element section from colliding with the magnetic disk while reducing the clearance between each head element section and the magnetic disk.
