摘要： A multi-vortex flowmeter (1) includes a vortex flowmeter for measurement by volume flow rate and a thermal flowmeter for measurement by mass flow rate to selectively use the two flowmeters according to the flow rate of fluid to be measured flowing through a flow channel (13). The multi-vortex flowmeter (1) uses the mass flow rate for a switching point. In other words, the multi-vortex flowmeter (1) has the switching point of two flowmeters based on the mass flow rate. A mass flow rate Qm at the switching point in a range larger than the minimum flow rate of a vortex flowmeter and smaller than the maximum flow rate of a thermal flowmeter is determined by: Qm=K3*√P, (where, P is a pressure of the flow channel (variable), K3 is a constant determined by the area and the vortex differential pressure of the channel (13) and a constant related to the vortex differential pressure, a density at 0° C. and 1 atm, and the pressure at 1 atm). Alternatively, a volume flow rate Q at the switching point in a range larger than the minimum flow rate of a vortex flowmeter and smaller than the maximum flow rate of a thermal flowmeter is determined by: Q=K1/√P, (where, P is a pressure of the channel (variable), K1 is a constant determined by the area and the vortex differential pressure of the flow channel (13) and a constant related to the density at 0° C. and 1 atm, and the pressure at 1 atm).

摘要： Damage of a connection between a connector and a circuit board on which the connector is mounted is to be prevented at the time of connecting the connector with a corresponding connector on a host side. In one embodiment, an HDD is provided with a serial ATA connector. The connector is mounted on a circuit board. The HDD is also provided with stiffeners for fixing the connector to the circuit board. When the connector moves toward a base at the time of connection thereof to a host-side connector, the stiffeners come into abutment against the base to stop the movement of the connector. As a result, damage of the connection between the connector and the circuit board can be prevented.

摘要： A dot matrix display system for multiple-tone displays, including a display device in which pixels are arrayed in a matrix shape, an LC (liquid-crystal) drive signal generator which converts color display data into LC display data, an 8-level data driver which selects one of 8-level voltages in accordance with the LC display data and then delivers the selected voltage, and an 8-level applied LC voltage generator by which the 8-level voltages to be applied to the pixels are produced so as to substantially make uniform color differences between the respectively adjacent tones of the multiple-tone displays. Owing to the substantially uniform color differences between the respectively adjacent tones, multiple-tone displays which are uniformly seen by the human eye can be obtained.

摘要： A bearing structure used in a pivot bearing for freely supporting the rotation of a head arm of a hard disk drive (HDD). The bearing structure includes an inner shaft, an outer sleeve, a pair of roller bearings axially spaced and interposed between the inner shaft and the outer sleeve, and a preload spring for exerting a preload on the roller bearings. The roller bearings may be provided with an outer race that is attached to the outer sleeve. Nevertheless, the coefficients of linear expansion of the inner shaft and the outer sleeve are chosen so that they are different in an axial direction. Accordingly, the coefficients of linear expansion of the inner shaft and the outer sleeve are chosen so that the rotation torque derived from the preload becomes higher as the temperature rises and lower as the temperature falls. However, the rotational torque becomes lower as the temperature of a lubricant rises and higher as the lubricant temperature falls. Thus, the changes in the rotational torque as a result of temperature change are cancelled out.
