In a design-system distributing method, when a server side design system is updated, a server compares an updated server side design system and a client update state data, and the server distributes an update assisting system, an update indication data and a difference data to a client system based on the comparing result. The client system stores the update assisting system, the update indication data and the difference data, and the client system starts the stored update assisting system such that an update notice is outputted to a user of the client system to urge update of the client side design system each time a preset condition is satisfied until an update command of the client side design system is supplied to the client system. The client system updates the client side design system based on the stored update indication data and the stored difference data in response to the update command. The client system generates and transmits the client update state data to the server to indicate an update state of the client side design system for this time, and the server updates the client update state data based on the client update state data received from the client system.

A master device transmits a beacon signal including information related to a proximity wireless communication area in a predetermined cycle by using a transmission power which allows the beacon signal to reach beyond the proximity wireless communication area. When a slave device receives the beacon signal from the master device, the slave device estimates a distance to the master device in accordance with the information of the beacon signal. When a wireless communication terminal is located within the proximity wireless communication area, the slave device is connected to the master device by using a proximity wireless communication.

In this signal detection device (100), a delaying unit (101) delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of T1 to form a first multiplication signal, and delays the one for a period of time of T2 (T2>T1) to form a second multiplication signal. An integrator (104) calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator (105) calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit (108) evaluates whether the signal to be detected, which is a periodic signal with a period of T1 or a periodic signal with a period of T2, exists or not, on the basis of the first correlation value and the second correlation value.

A conventional packet frame includes a MAC header, one MAC service data unit (MSDU) and a frame FCS. This frame is repeated to send a plurality of MSDUs. A proposed packet frame includes a MAC header, a plurality of MSDUs and a frame FCS. A unique bit pattern is provided in the MAC header to distinguish the proposed packet frame from the conventional packet frame. Thus, the total data stream can be shortened.

The present invention provides a method for transmitting data stream via wireless medium for contention based medium access across a wireless network having a plurality of stations and an access point communicating to the stations via wireless medium. The method includes: (i) transmitting data stream from the station according to prescheduled wireless medium occupancy reservation for the station within only prescheduled medium occupancy period of a selective contention period; (ii) performing a contention between the stations for wireless medium occupancy for a contention successful station to transmit data stream within only contention medium occupancy period of the selective contention period; (iii) transmitting data stream from the contention successful station after the contention; and (iv) prescheduling a wireless medium occupancy reservation for the contention successful station to transmit within a prescheduled medium occupancy period of next selective contention period.

In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, an unstabilizing agent is provided to the image holding member. An attaching state between the image forming substance and the image holding member stably attaching the image forming substance on a surface thereof is changed to an unstable state by the unstabilizing agent. The image forming substance is separated and removed from the image holding member by making a separating member come in close contact with the image forming substance on the image holding member having the provided unstabilizing agent. A processing situation mark showing a processing situation of removal of the image forming substance is formed in the image holding member. The processing situation mark can be removed from the image holding member by the image forming substance removing processing.

A master station performing continuous operations is communicatively coupled with a plurality of remote stations performing intermittent transmission/receiving operations in constant cycles. Control units of the remote stations control radio communication devices to transmit synchronizing signals to the master station in constant cycles respectively. When the synchronizing signals are received from the remote stations, a control unit of the master station acquires information of corresponding intermittent receiving timing from a memory device, and controls a radio communication device to perform transmitting operations to the remote stations in coincidence with the intermittent receiving timing. Further, the control unit of the master station reads random number values from a random number generator in re-transmission of data, and shifts data transmission timing from original timing by time corresponding to the random number values. On the other hand, the control units of the remote stations read random number values from random number generators in re-receiving of the data, and shift data receiving timing from original timing by time corresponding to the random number values. Thus, the data collision probability is reduced.

A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc. Thereafter, the transfer paper sheet is discharged onto a paper discharging tray. Accordingly, it is possible to provide a method and an apparatus for regenerating and reusing the transfer paper sheet by removing the toner therefrom without damaging paper fibers.
