Abstract: A battery holding device includes a battery holder and a second wireless communication unit. The battery holder is configured to be mountable on a human-powered vehicle. The battery holder includes a battery connector connected to a battery. The second wireless communication unit is provided on the battery holder. The battery connector is removably connected to the battery. The second wireless communication unit is removably attached to the battery holder.

Abstract: CPU of an air conditioner reads out a heat exchanger outlet temperature stored in time series into a memory part to check whether the current heat exchanger outlet temperature is a second threshold temperature or lower or not, whether the drop rate of the heat exchanger outlet temperature calculated using the latest heat exchanger outlet temperature and the second-to-the-latest heat exchanger outlet temperature is a specific drop rate or higher or not, and whether the number of indoor units in operation of indoor units has increased or not during calculation of the drop rate of the heat exchanger outlet temperature. And, when the second frost forming condition is satisfied, CPU switches a four-way valve to set a refrigerant circuit into a cooling cycle to thereby execute a defrosting operation preparation processing and, on completing the defrosting operation preparation processing, resumes a compressor to start a defrosting operation.

Abstract: A cooling unit is provided to an image forming device. The image forming device includes a process unit having a photosensitive body on which is formed an electrostatic latent image and a developing unit for forming a toner image on the photosensitive body based on the electrostatic latent image; a transfer unit that transfers the toner image onto a sheet; and a fixing unit that thermally fixes the toner image onto the sheet, the process unit and the fixing unit having facing surfaces that face each other. The cooling unit itself includes: an airflow duct disposed between the facing surfaces of the process unit and the fixing unit and formed with at least either process-unit-side holes facing the process unit or fixing-unit-side holes facing the fixing unit; and a cooling fan that draws air from around a corresponding one of the process unit and the fixing unit through the process-unit-side, the fixing-unit-side holes, or both, through the airflow duct, and out of the image forming device.

Abstract: In this developing toner supply device, the main body of a toner cartridge having an unused toner storing room is designed in a longitudinal vessel shape. A projecting portion is projected from the front wall of the cartridge at the casing side to engage with the recess portion of a toner storing portion. A semi-circular support wall is formed at the projecting portion to project toward the unused toner storing room side. A longitudinally-extending cartridge side opening is formed on the support wall. A semi-cylindrical cartridge side rotating member engages with the cartridge side and opens rotatably between the closing position where the cartridge side opening is closed and the opening position where the cartridge side opening is opened. When the toner cartridge is detached from the casing, the cartridge side opening is closed. The flat side surface of the cartridge side rotating member serves as the outer surface of the toner cartridge.

Abstract: A called facsimile unit stores image data received from a calling facsimile unit in its memory. When communication is established between another calling facsimile unit and the called facsimile unit designates the received image data which has been received and stored in its memory as image data to be sent to the another calling facsimile unit, the called facsimile unit transmits the received image data to the another calling facsimile unit.
