摘要:
A camera with a flash device that includes a manually operable member. The camera has a capability for controlling exposure, for detecting a completion of charge of the flash device, and for counting a lapse of time from the operation of the manually operable member. The camera also has the capability to allow the control of exposure when the completion of charge is detected, and for forbidding the control of exposure when a predetermined time is counted without the detecting of the completion of charge.

A first position information generation unit (130) generates, based on a first radio signal received by a first wireless communication unit (110), first position information representing a position where the first radio signal is received. A second position information generation unit (140) generates, using the first position information, second position information representing a position where a second wireless communication unit (120) can receive a second radio signal. A wireless communication operation determination unit (150) determines, based on the generated first and second position information, whether the operation by the second wireless communication unit is possible. A power supply control unit (160) executes power supply control of the second wireless communication unit in accordance with a determination result. This allows to uniquely determine the position information of a mobile communication terminal apparatus by simple signal processing at a low cost and implement power supply control of wireless communication functions based on the position information.
摘要:
An electric power conversion device comprises a conversion circuit having bi-directionally switchable plural pairs of switching elements connected to respective phases and converting an inputted AC power into an AC electric power. A first switching time is calculated using detected voltages detected by voltage sensors and an output command value. A second switching time is calculated using a carrier and the first switching time. A control signal generating section generates control signals to switch on and off of the switching elements using the first switching time and second switching time. In a case where a state is transited from the first switching time to the second switching time, a controller tarns off one of on state switching elements of either one of an upper arm circuit or a lower arm circuit and maintains on state of the other of the on state switching elements of the other arm circuit.

In a method of making an electronic apparatus, electronic devices and a mold are placed in a package such that pads of electronic devices are covered with the mold. An electrical insulator is poured into the package, in which the mold is placed, to fill the package. The mold is removed from the electrical insulator to form a space where the pads are exposed. An electrical conductor is placed in the space such that the pads are electrically connected together through the electrical conductor. The electrical conductor is in the form of a liquid or a solid having both fluidity and deformability.

A T-SIR generation unit (106a) generates, on the basis of an actual reception quality (205) in a mobile communication terminal, a target value T-SIR to be used to control transmission power of a base station from the mobile communication terminal. When the mobile communication terminal exists in the service area of a predetermined specific communication carrier, a T-SIR correction unit (106b) adds a correction value K to the T-SIR generated by the T-SIR generation unit (106a). Even when a reception SIR abruptly deteriorates in a communication carrier with a strong reception field and a low BLER, it does not drop below the SIR limit value of the mobile communication terminal. Hence, the terminal can receive the signal from the base station and continue a service such as speech communication. When a long-term BLER measurement result is used instead of a BER, stable transmission power control can be done normally.
