An AP allows a CTS generator provided within a control unit to generate a self-destined, e.g., IEEE802.11b standard-based CTS signal containing a duration time corresponding to each standard. Then, the AP notifies to each STA operated based on the 11b standard in a basic service set, that it is being ready for transmission due to the transmission of the CTS signal, thereby to prohibit the operation of the corresponding STA. Further, the AP transmits a beacon based on an IEEE802.11g standard to thereby set a condition based on this standard and is caused to perform transmission/reception to and from the corresponding STA alone over the duration time indicated by the 11b standard. In a reverse case, the AP transmits a CTS signal containing a self-destined duration time under the IEEE802.11g standard to prohibit the operation of the corresponding STA based on the 11g standard. Further, the AP transmits a beacon based on the 11b standard to thereby set a condition based on this standard and is caused to perform transmission/reception to and from the corresponding station alone over the duration time indicated by the 11g standard.

To prevent an air bag from being operated by mere inclination when the vehicle body does not fall down, that is, at the time of handling during a banking operation or the like. An air bag and a removal detecting part for detecting a rider removal from a vehicle body are incorporated in a rider jacket. An inclination sensor for detecting an inclination of the vehicle body of a motorcycle is provided. An angle acceleration calculating part for calculating the inclination angle acceleration of the vehicle body calculates the inclination angle acceleration based on a plurality of detected inclination angles. When the state of the vehicle body falls within the air bag operable range, an air bag deploying instruction is outputted. The air bag deploying instruction is supplied to the air bag when the rider removal from the vehicle body is not detected by the removal detecting part.

A method is disclosed for controlling a crane which comprises a boom that may be raised or lowered by angular adjustment of the boom about a base portion of the crane. The method prevents operation of the crane in an undesired condition by continuously monitoring operation of the crane, including monitoring at least the position of the boom with respect to the base of the crane. If the crane approaches a limit of its operating range or any operational parameter, its operation will be controlled so as to selectively prohibit or permit a boom raising operation of the crane, depending on the cause of the condition, rather than uniformly prohibit such an operation.

A switching frequency setting unit sets switching frequency of a switching element, based on both the temperature of a cooling medium which cools a DC-DC converter and the temperature of a switching element of the DC-DC converter. A switching controller controls the voltage conversion ratio of the DC-DC converter by controlling switching operation of the switching element at the set switching frequency.

The optical disc apparatus according to the present invention includes a tilt detecting means; a coma aberration correcting means; and a spherical aberration correcting means. Based on the result of a tilt detection, the amount of the correction performed by the coma aberration correcting means is determined so that the amount of correction is constant for the whole circumference of an optical disc, and then a spherical aberration is corrected by the spherical aberration correcting means. Thus, it is possible to correct the spherical aberration that has occurred due to the coma aberration correcting means, while the tilt margin is secured, thereby improving the reliability of reproduction and recording by the optical disc apparatus. Further, the optical disc apparatus according to the present invention is configured, in the case where a thermal shock tilt has occurred during the activation of the apparatus, to wait until the thermal shock tilt has settled. Thus, it is possible to perform the activation while the influence of the thermal shock tilt is avoided, thereby improving the reliability of the recording and reproduction operations by the optical disc apparatus.

In an optical disk, while restricting a program area which has been defined as to the normal disk and on which a user can record arbitrary information, a remaining area located outside this restricted program area is previously secured as an advertisement area where an advertisement-purpose visible image is formed. In the case that an advertisement-purpose recordable optical disk is loaded on an optical disk recording apparatus, the optical disk recording apparatus accesses via a pubic line network to an advertisement information distributing apparatus so as to acquire advertisement image information. Next, the optical disk recording apparatus irradiates an optical beam to the advertisement area in response to the acquired advertisement image information so as to reproduce the advertisement image.

Provided is a power factor correction circuit capable of reducing ringing sound of a transformer produced when an overshoot protection is effected. An output voltage control circuit performs constant voltage-control such that capacitor charge voltage of an output capacitor corresponds to a first voltage value, and when the capacitor charge voltage of the output capacitor reaches a second voltage value higher than the first voltage value, an overvoltage detecting unit detects the second voltage value. Further, a current limiting unit detects a value of a switching current through a switching element, and determines a limiting value of the level of the switching current. Then, the switching current is limited to the limiting value, and when an overvoltage detecting unit detects the second voltage value, a limiting value changing unit causes the current limiting unit to change the limiting value to decrease the value of the switching current.
