Abstract: A data storage control device including a DRAM and a storage device has an address bus common to the DRAM and the storage device, and a control device for selectively applying an address signal relating to the DRAM and another address signal relating to the storage device to the address bus.
Abstract: A camera has a shutter which may also constitute a diaphragm. In a multi-flash mode the shutter selectively has a maximum aperture at an onset or at the end of the time base. The flash occurs in synchronism with a shutter waveform shaped by this aperture area and a time base element. In a second embodiment, a second diaphragm setting circuit is provided, in diaphragm priority photography, for computing a measurement value of a distance to a subject and a second diaphragm value from the guide number during an emission of flashed light. The diaphragm is set to the computed second diaphragm value, ad an electronic flash is energized with a desired aperture area. The diaphragm is set to an initial value to effect the photography at a time other than during the emission of flashed light. A timing circuit may be provided for setting the diaphragm to the second diaphragm value.
Abstract: A desk top cleaner for cleaning dust from the top of a table includes a crankshaft rotatably supported in a frame. A broom is formed with an elongated slot to engage with the crankshaft and has its upper end portion fitted in a supporting portion formed in the frame and its lower end portion equipped with a brush. A drive mechanism is provided for transmitting a rotating force from a drive source to the crankshaft. A dust case for accommodating the dust swept by the broom is included in the frame.
