Organohalosilanes are prepared by charging a reactor with a contact mass comprising metallic silicon and a catalyst and feeding an organohalide-containing gas to the reactor. The contact mass is prepared by premixing metallic silicon and a tin compound and heat treating the premix at 300-600° C. in an inert gas atmosphere.

The present invention provides a system for wireless data communications that allows, in P-MP wireless data communications, equally giving communications opportunities to mobile stations that directly communicate with a wireless base station and mobile stations that indirectly communicate therewith via a relay station and a communications method thereof. In comparison with the OFDM frame configuration prescribed in IEEE802.16, an OFDM frame configuration is characterized in that, in an uplink subframe, a ranging period and BW (bandwidth) request periods for a relay station are provided, and furthermore, a remaining message number notice period for which each relay station notifies the wireless base station of the number of remaining messages is provided. These periods are not of a contention base but bandwidths dedicated to the relay station.

A non-volatile storage device (1), such as a flash memory, that may include a plurality of sectors and additional sectors has been disclosed. Sectors may include a physical sector number. A logical sector number may be assigned to a sector with additional sectors not assigned a logical sector number. When an erase/write command is executed for a logical sector address, an additional sector may be selected to have the new or updated data written into and may be assigned the logical sector number. The additional sector assigned the logical sector number may then have the new or updated data written into while the physical sector number previously assigned the logical address is being erased. In this way, an apparent erase time may be reduced. The newly erased sector may be a new additional sector. Each sector may include a control data section (101) and a data section (102). Control data section (101) may store control data for controlling erasing and rewriting.

The electronic camera is provided with an image pickup device which picks up an image, an image processing device which outputs the picked up image to a recording medium and at the same time records the image in a memory capable of executing a writing process or reading process with a speed higher than that of the recording medium, and a display device which displays the image. In case of reproducing and displaying the image, the image recorded in the memory is read and displayed on the display device, and therefore it is possible to reproduce and display the image in a short time.
