A transmission system includes a transmission apparatus and a receiving apparatus for repeatedly transmitting and receiving a frame with plural time slots at a constant frequency, in which digital audio data of plural channels and auxiliary data required to playback the digital audio data are transmitted using previously allocated time slots. A multiplexer is provided for multiplexing, assuming an area made up of previously allocated time slots that are included in respective frames amounting to a number of a multiple of n as block data when the predetermined encryption unit is n bytes. The digital audio data and the auxiliary data are allocated as the block data wherein the auxiliary data is allocated to the time slots that are located at the same positions of respective plural frames within the block data, and the digital audio data is allocated in the time slots that are located at the same position in the respective frames amounting to the number of a multiple of n in the block data. An encryptor encrypts at least the digital audio data from the multiplexed block data in the predetermined encryption unit and a communication unit transmits the data encrypted in the encryptor, wherein the receiving apparatus decodes the encrypted data transmitted from the transmission apparatus.

In a display system, a projector is mounted inside a vehicle, and emits a light beam, which is generated based on an image signal, toward an opening formed at a portion near a rear end of the vehicle. An exterior screen is extendable toward the opening and is made of a material having low stiffness. While being extended toward the opening, the exterior screen displays an image by allowing the light beam emitted by the projector to pass therethrough. A screen housing unit is mounted on or near one of a rear hatch and a back door of the vehicle for accommodating the exterior screen.

The present invention provides an apparatus and method for coding moving pictures, which reduces a delay time generated by buffering of a decoding apparatus in compressive coding of the moving pictures. In this invention, the target number of bits of one picture P as a target value of the number of generated bits per one picture is set as well as the upper limit number of bits uCg as an upper limit value of the number of generated bits of the picture is set. Then, when the cumulative number of generated bits Cg generated from the first macroblock to a macroblock which is being coded in the picture exceeds the upper limit number of bits uCg in the middle of the picture which is being coded, the coding of a macroblock is skipped to avoid underflow. When the cumulative number of generated bits Cg does not reach the target number of bits of one picture P after the picture has been coded to the end, the stuffing is performed so that the cumulative number of generated bits of one picture Cg reaches the target number of bits of one picture P.

Composite crimped yarn comprising 50-90 wt. % of cellulose filaments and synthetic fiber filaments and having a crimp elongation percentage of 0.1-4.0%; and a weft knitted fabric comprising the composite crimped yarns. A weft knitted fabric comprising the composite crimped yarns does not substantially have weft bar has a high-quality appearance, a glossiness and hand touchness of the cellulose filaments, and excellent shrinkage proofing properties and setting properties, so that this weft knitted fabric can be applied to clothing goods, such as inner wear, sports wear and outer wear which are required to have excellent, a wet strength, dimensional stability and a high quality of knitted fabric.

There is herein disclosed a semiconductor device comprising an internal cell area 1 on which various logic circuits are formed, an I/O cell area 3 via which a signal is received/transmitted between a pad for connection to the outside and said internal cell area 1, an external pad area 2a formed outside the I/O cell area 3, and an internal pad area 2b formed between the internal cell area 1 and the I/O cell area 3. Since the internal pad area 2b is disposed not only outside the I/O cell area 3, but also between the I/O cell area 3 and the internal cell area 1, the number of pads for the connection to the outside can be increased more than that of a conventional art, and a large number of pins of a chip can be handled. Moreover, since a pad interval does not have to be narrowed, reliability is improved, and manufacture yield is raised.

A frame-and-door unit includes of a frame structure and a door. A first vertical frame of the frame structure is supported on one side portion of the door by hinges. When the door is closed, a second vertical frame of the frame structure is supported on the other side portion of the door by a latch bolt and a strike. The unit is bound tight with a band that extends across the door. Each of the vertical frames is formed having a band groove along which the band is passed. The unit, kept bound tight with the band, is fitted into a door opening of a building. The band is cut after the vertical frames are fixed to the edge of the door opening. The cut band is then removed from between the edge of door opening and the vertical frames.

When a retrieval condition designating unit designates "data to be retrieved" and "retrieval condition" as data on retrieval of a document, and a classification attribute designating unit designates a "component's name" as data on classification of the document, a structured document retrieving unit first retrieves a structured document group among a plurality of structured documents stored in a structured document storing unit on the basis of the designated "data to be retrieved" and "retrieval condition" and transfers the document group to a structured document classifying unit, which classifies the document group on the basis of the designated "component's name". The result of the classification is displayed on a display unit. Thus, by designating the components constituting a structured document by their component's names, a plurality of structured documents is retrieved and classified on a real time basis.

A region comprising a plurality of real pages in a part of a real storage unit is provided with a first key storage unit having a plurality of key storage entries each corresponding to one of the plurality of real pages, while a second region comprising a plurality of real pages in the second part of the real storage unit is provided with a second key storage unit having a single key storage entry. When a real address designated by an instruction to be executed belongs to the first region, an entry corresponding to this address is accessed by a storage protection control circuit. When this address belongs to the second region, the second key storage unit is accessed irrespective of the address. Further, a key within the accessed key information is compared with a key on a program status word (PSW) allocated to a program to determine whether the execution of the instruction is permitted.
