Provided is a portable brush cutter with reduced weight and size due to its simple structure with a small number of components that is capable of improving durability and the like as well as effectively suppressing torsional vibration of a transmission shaft. In the portable brush cutter, a one-way clutch to prevent generation of torsional vibration in a rotation transmission path is interposed between an output shaft and a transmission shaft, and bearings are adjacently mounted on the opposite sides of the one-way clutch.

In case that a call connection request message is transmitted from an originating call side and in case that a user on a termination call side cannot make a response over the telephone due to his or her absence, the call connection request message is stored on the termination call side, and in case that the user on the termination call side returns to his or her seat and selects folded communication processing of the received call connection request message, the call connection request message is transmitted by return by means of an address on the companion originating call side, which is included in the received call connection request message, and on the originating call side, in case that call connection cannot be established due to absence of the user on the termination call side, an address of the originating call side is stored, and in case that a folded call connection request message is received from the originating call side, a previously selected response processing is conducted.

A MCU unit of a video-meeting control system includes a volume level detector for detecting volume levels of a plurality of meeting terminals, a speaker terminal selection block for selecting a speaker terminal having a maximum volume level, mixing the voice data based on volume levels detected, and a mixer for mixing the voice data based on a specified mixing level of the speaker terminal, and transmitting the video data and the mixed voice data to the meeting terminals. The specified mixing level of the speaker terminal emphasizes the volume level of the speaker terminal.

The invention provides a character and picture data compression apparatus which can collectively compress document data of the character code form and still picture data and moving picture data of the bit map form. A conversion section converts document data of the character code form into those of the bit map form. A display image composition section composes the document data of the bit map form, still picture data of the bit map form and a first one frame of moving picture data into a display image of the first page, and then produces, for each of the succeeding frames, a display image wherein the moving picture data portion in the display image of the first page is replaced with moving picture data of the frame. A difference processing section calculates, for each of the display images of the succeeding pages, a difference from the display image of the immediately preceding page in the bit map form. A bit map data compression section successively receives the display image of the first page and the display images of the succeeding pages obtained by the difference processing section and performs compression of the images in units of one page.

A data browsing apparatus displays data automatically in an automatic page-turning mode. The data browsing apparatus has dynamic picture display parameters comprising a frame display time (w), a frame display pitch (m), and a display priority (r). The dynamic picture display parameters may be calculated based on automatic page-turning options designated by users. Dynamic pictures are displayed with accuracy at the automatic page-turning interval.

Before dither-processed data are input to a compression processing section, dither-processed data of a previous frame and dither-processed data of a current frame are subjected to inter-frame differential processing in a differential processing section to form signal series having long white and black run length for the data input to the compression processing section, thereby enhancing the compressibility. A coding control section for performing coding processing beforehand sets a flag for determining whether each of the dither processing, the differential processing and the compression processing is performed. Each processing is performed on the basis of the flag information.
