The female screw () is formed on the inner circumference of the forward side of the piston receiving hole () in the cylinder body () and the movable stopper () is screwed into the female screw (). The piston () is located at the stroke end of the forward side when its end face of the forward side is contact with the end face of the backward side of the movable stopper (). The rotating knob () is rotatably mounted on the end of the forward side of the cylinder body (). The rotation transmitting pin () is projected on the end face of the backward side of the rotating knob. The rotation transmitting hole () is formed on the end face of the forward side of the movable stopper (). The rotation transmitting pin () is slidably inserted into the rotation transmitting hole. When the rotating knob () is rotated, the movable stopper () is screwed into so that the stroke end position and the moving stroke of the piston () can be adjusted.

Each of two members to be fastened has a connecting surface, a communication groove opening on the connecting surface, and an engagement groove communicating with the communication groove and having an engagement surface parallel to the connecting surface. A fastening assembly has a connecting portion and two engaging pieces, each engaging piece having a fastening surface. The two members are placed with the connecting surfaces opposed, so that the engagement grooves are in communication each with the other through the communication grooves. The fastening assembly is inserted into the engagement grooves and the communication grooves, and the connecting portion is operated to draw together the two engaging pieces, causing the fastening surfaces of the engaging pieces to press upon the engagement surfaces of the engagement grooves, thereby clamping the two members together through their opposed connecting surfaces.

A data demultiplexer includes a write controller, a memory, an analyzing processing unit, and transfer control units. The write controller writes packets which have arrived thereat into the memory in the order of arrival and sends the write information to the analyzing processing unit. The analyzing processing unit analyzes packets in the order of arrival on the basis of the write information and sends only the result of analysis to the transfer control units. On the basis of the result of analysis, the transfer control units send data read from the memory in the order of packet arrival to the decoder. A data demultiplexer capable of reducing the processing in the analyzing processing unit can be provided.

Data demultiplexer

In a moving picture data decoding apparatus, the storage of reference picture data in a picture memory is executed by dividing the picture memory into two memory areas. An address generator generates an address so that the reference picture data adjacent to the division may be doubly written into the two memory areas. As a result, the processing can be effected in a predetermined access time period irrespective of the read-out location.

Apparatus for decoding moving picture data

In order to increase a coded data buffer size and provide an OSD area within a 16 Mbit memory for picture signals of NTSC and systems, a display data area of the memory is made 2(N+1)/4N times a frame when a picture size is large.
