Abstract: A residential facility control system transmits data as a radio signal between host and subsidiary apparatus. Transmitting and receiving devices of the host and subsidiary apparatus are reduced in power consumption. A transmitting circuit of the transmitting device of the transmitting and receiving apparatus is supplied with power from a transmitting circuit power source control in synchronization with a first timing signal from a first timer for a period of time which is necessary for transmission. A receiving circuit of the receiving device of the transmitting and receiving device is supplied with power from a receiving circuit power source control for a shorter period of time in synchronization with a second timing signal from a second timer which is synchronized with the first timing signal.

Abstract: This serial data receiving apparatus is intended to realize the receiving process of serial data having an inferior SN ratio with a simple arrangement and at low cost. A one-bit length of the serial data is divided into several blocks. The sampling data is input at the multiple points of each block by using a shift register built in a microcomputer. The data is temporarily held so that the data at the same number block of each block is accumulated for several bits. The accumulation of the data results in cancelling the noise components and leaving the original signal components. This overlapping type receiving system makes it possible to clarify the receiving phase of a preamble signal for bit synchronization and to establish the bit synchronization. Next, the sampling data signals are entered at the multiple points based on the resulting receiving timing and the logic value of the bit is determined according to the ratio of the number of values of "1" to "0" contained in the data.

Abstract: For use in a photocopying machine, an apparatus for making punch holes in and stapling recording sheets comprising, a first conveyer by which the recording sheets are conveyed to a sheet stacker which is capable of setting the recording sheets at a predetermined position for sheet processing, a sheet processor which has a hole puncher and a stapler by which the recording sheets are processed to have punch holes or to be stapled, or both, in which the hole puncher is provided with an angled panel attached below a die of the hole puncher so that paper pieces punched from punch holes are received without clogging into a container for disposal, and a second conveyer by which the processed sheets are conveyed to a sheet receiving tray.

Abstract: A recorded sheet handling apparatus includes a holding unit for temporarily holding a set of recorded sheets externally fed one by one, a pair of side plates for moving the recorded sheets by a predetermined distance in a direction perpendicular to a recorded sheet convey direction prior to stapling when a size of the recorded sheets is a predetermined size, a punching machine and staplers for punching or stapling the set of recorded sheets while the sheets are held by the holding unit, and a conveying unit for conveying the punched or stapled copied sheets so as to exhaust the sheets.
