摘要:
A motor control apparatus for controlling a motor with reduced noise and vibration includes a detecting means for detecting a rotational speed of the motor, a command signal processing means that generates a command signal for allowing the motor to rotate at a predetermined rotational speed, a drive means that generates a drive signal based on the command signal and supplies the drive signal to the motor, and a control signal generation means that generates a control signal for allowing the motor to produce a control torque having a frequency equal to one of frequencies of noise and vibration due to the motor. The frequency of the control torque corresponds to at least one of orders of the rotational speed detected by the detecting means. The command signal processing means generates the command signal based on the control signal.

An error detection method for detecting an error of control information (parameters) of a physical channel and a mobile terminal are provided. In a receive side (mobile terminal), the size of each bit string generated in the transport channel HS-DSCH (High-Speed Downlink Shared Channel) processing (e.g. rate matching processing) in HSDPA (High-Speed Downlink Packet Access) is compared, so that an error of the control information, transmitted from the transmission side (base station) via the physical channel for control information HS-SCCH (High-Speed Shared Control Channel), is detected.

The opening and closing device involves a stationary member, a stationary cam, a rotary cam, a rotary member, a spring disposed between the stationary member and the stationary cam which pushes the stationary cam against the rotary cam, and a shaft passing through the stationary member, the stationary cam, the spring, the rotary cam and the rotary member. A head of the shaft holds the stationary member or the rotary member rotatably at its first end, and a caulked portion of the shaft fixes the shaft to the rotary member or the stationary member at its second end. Upon opening or closing operation, the stationary member or the rotary member, which is fixed to the shaft, rotates with the shaft integrally, causing no wear. The opening and closing device can realize smooth and sure operation without irregular feeling.

To realize smooth adaptive modulation control after handover even when the transmission frequency of parameters is lowered with transmission of the parameters used for the adaptive modulation control with timing satisfying predetermined conditions. As the mobile station for transmitting the parameters used for the adaptive modulation control in the timing satisfying the predetermined conditions, a mobile station comprises a transmitting unit for transmitting the parameters with the timing not satisfying the predetermined conditions.

A transmitter apparatus 1 transmits transfer data having a predetermined amount to a receiver apparatus. The apparatus 1 includes: a data packet generating section 132 dividing the transfer data into multiple divisional data sets; an error detection/correction code adding section 133 adding an error detection code (error detection information) by which an error in the divisional data sets is detected to each of the divisional data sets; and a transmitter section 14 transmitting the multiple divisional data sets to which the error detection code is added all together. Thus, data transfer is very reliable. It takes less time to transfer data.

An arbitrary position of a pipe is clamped and a connector is engaged with the pipe. Then, an end portion of the pipe is expanded with a tool such as a diameter expanding punch so as to caulk the pipe to the connector from inside. As a pipe fluctuation-absorbing portion, which is a relief space of pipe material, is provided in a portion of an inner face of the connector, when the diameter-expanding portion is formed, an excess pipe material is absorbed there and the length of the pipe is reduced and adjusted to an appropriate value. A portion in which the pipe fluctuation-absorbing portion is formed is not limited to a forward end portion of the pipe but it may be formed on an inner face of the connector corresponding to an intermediate portion.

The invention is to provide a folding device comprising a fewer number of components and low in cost and a method of mounting the same to a various kinds of electronic apparatuses. Folding device 25 is constructed with holding member 23 mounted rotatably on an end portion of movable case 21, which is formed on its periphery with convex wall portion 21A, and which houses fixed member 1 and movable member 3. Holding member 23 provided in folding device 25 is rotated to fix movable case 21 in movable housing 13 after movable case 21 is inserted in movable housing 13.

A golf club head (11) has an ellipsoid of inertia (12) with its center at a center of gravity G. When the ellipsoid of inertia (12) is virtually cut with a plane passing through the center of gravity of the golf club head (11) and being parallel to a face surface (11f), a major axis of a plane ellipse (13) appearing on its cut surface forms an angle of &thgr; with an intersecting line (15) of the cut surface and a ground surface (16). The major axis extends upward and away from the ground surface (16) as it approaches a toe part (11t). The angle &thgr; is not smaller than 0.5° and not larger than 9.5°. An aspect ratio a/b defined by a ratio of the length a of the major axis (13d) to the length b of a minor axis (13e) of the plane ellipse (13) is not smaller than 1 and not larger than 4.
