A camera includes a liquid-crystal display device with a liquid crystal whose transmittance is variable. A liquid-crystal control section, in a release signal waiting mode, brings the liquid crystal of the liquid-crystal display device into the light-transmitting state and, when a release signal is output to turn on an exposure mode, lowers the transmittance of the liquid crystal of the liquid-crystal display device temporarily.

A battery check device for a camera which includes a discharging circuit to which current flows from a battery and a discharging time setting device for setting a discharging time for determining that an internal resistance of the battery has increased due to non-use of the battery so as to temporarily reduce an output voltage of the battery. The discharging time set by the discharging time setting device is longer than a time required to check the residual energy amount of the battery. A determining device determines whether a voltage of the discharging circuit has reached a reference voltage specific to the battery within the discharging time. It is determined that the residual energy amount of the battery is sufficient and that the internal resistance of the battery has merely increased due to non-use of the battery when the determining device determines that the voltage of the discharging circuit has reached the reference voltage specific to the battery within the discharging time but after the time required to check the residual energy amount of the battery. And it is determined that the residual energy amount of the battery is insufficient when the determining device determines that the voltage of the discharging circuit has not reached the reference voltage specific to the battery within the discharging time.

An objective is to provide a carrier exhibiting stable charge providing ability in which sufficient charge can be provided to toner having a small particle diameter, and no image contamination such as fog caused by toner scattering via lack of electrification is generated. Another objective is to provide a carrier capable of maintaining a charging level of no interference for image formation even under the image forming condition at which a charging level for printing a number of prints continuously is difficult to be maintained. Disclosed is a carrier comprising a core particle made of ferrite possessing Mg and coated thereon, a resin, wherein the core particle has a ratio of the number of irregular-shaped core particles of at most 5%, based on the total number of core particles, and a surface of the core particle has grains having a maximum grain diameter of 2-5 μm.

摘要:
A method is provided of manufacturing semiconductor devices formed on a semiconductor wafer, including placing the wafer in a semiconductor container and conveying the container to a semiconductor manufacturing apparatus. An opening of the container is opposed to an opening of the apparatus such that an opener of the apparatus holds a lid of the opening the container. A key of the opener is inserted to a latch groove of the lid, and the key is rotated to contact a latch of the lid. The openings are connected such that a velocity differential pressure ratio obtained by dividing the maximum velocity when the opener holding the lid horizontally moves away from the opening of the container, by the differential pressure between the inside pressure and the outside pressure of the apparatus, is set to be 0.06 ((m/s)/Pa) or less, and then the wafer is processed.
