IPC: G11B23/087
Filed: 1992-02-24
Abstract: PURPOSE:To obtain an improved tape traveling system, and suppress generation of a defect of a tape while the tape is traveling. CONSTITUTION:Guide members 34-38 which guide a magnetic tape 12 are constituted of ribs 34a-38a which are formed in one piece at a base plate 31 and tape contacts 34b-38b which are loaded into the ribs 34a-38a.

Title: Method and circuit for controlling slice signal of character broadcast signal
Inventor: MINAMI YUJI
IPC: H04N7/035
Filed: 1990-02-16
Abstract: PURPOSE:To always adjust a slice signal to an optimal level by varying a slice level of the slice signal in accordance with the number of corrections at the time when it is decided to be an error by an error correcting circuit and one data is decided to be the other data. CONSTITUTION:When '1' is decided to be '0' by an error correcting circuit 4, a pulse is outputted from a first gate circuit 16, and counted by a first counter 18. Also, when '0' is decided to be '1', as well, a pulse is outputted from a second gate circuit 17, and counted by a second counter 19. Outputs of these first and second counters are compared by a comparing circuit 22. In such a state, when a value of a first counter is larger than a value of a second counter, a ratio in which '1' is decided to be '0' is large. Accordingly, since a slice level is higher than a normal value, the control is executed in the direction for lowering the slice level by an output of the comparing circuit. On the contrary, when the value of a first counter is smaller than the value of a second counter, the control is executed in the direction for raising the slice level.

Title: Preparation of metal composite having fine particle dispersed therein
Inventor: OSADA SUMIO
IPC: C22C1/05
Filed: 1981-03-10
Abstract: PURPOSE: To provide a composite having fine particles dispersed uniformly in its metallic base. by putting the same kind of metal in a semi-cmolten state as the coarse particles of a metal into a mixture of them and inorganic fine particles under pressure in prefaring of the composite of the metal and inorganic fine particles.  
     CONSTITUTION: The homogeneous mixture of coarse particles 1 of a metal and dispersed fine particles 2 of graphite or the like is packed into a solid mold vessel, and then, after preheating of the mixture at a specific temperature, the same kind of molten metal as the particles 1 is put into the gaps of the packed layer under pressure with a hydraulic press or the like. The metal pushed by pressure goes into the gaps between particles in a semi-molten state, so that the inside of the mold is filled with the metal. As the metal is in a semi-molten state, it solidifies immediately after that, so that it dos no longer leak out of the mold. Therefore a pressure for pushing the molten metal continues to act sufficiently until the metal solidifies, serving such to bond the molten metal to particles 1 and 2. Therefore the molten metal 3 flows into the mixed layer of particles 1 and 2 and thus the gaps of the layer are filled with the molten metal 3. As the metal of particles 1 and the metal 3 are of the same kind, they are easily united into a body and boundaries between them disappear. Thus, the composite having particles 2 dispersed in its metal base is obtained.

Abstract: PROBLEM TO BE SOLVED: To minimize fluctuation and degradation in image quality due to mismatching between an input coded signal a re-coded signal by using an existing decoder and an existing coder. SOLUTION: In the transcoder, a video decoder 102 decodes once a video elementary stream ES signal onto an original video signal, a video encoder 103 again encodes the video signal at an optional transmission rate so as to easily change the transmission rate of the video ES signal, a multiplexer section 104 multiplexes an output of the encoder 103 and an output of an audio processing section 105 into a transport stream TS signal. A group of picture GOP detection section 107 detects GOP header information from the input video ES signal and a coding reset section 108 gives a start trigger signal to the video encoder 103 after the lapse of a time required for decode processing by the video decoder 102 on the basis of the result of detection so as to apply start trigger to the coding processing of the video encoder 103.

Abstract: PURPOSE:To eliminate the designation of words and phrases being key words at every time and to reduce the burden of a user by providing a key word extraction part which automatically extracts the key words from the content of a document data buffer and a key word buffer holding the extracted key word. CONSTITUTION:The key word extraction part 11 automatically extracts the words and the phrases registered in dictionaries 5, 6 and 7 among document data by using given document data and the dictionaries 5, 6 and 7 used for KANA (Japanese syllabary)-KANJI (Chinese character) conversion. The dictionaries used at that time are set to be the dictionary 6 to which the user can register the words and the phrases, and the dictionary 7 to which technical terms are previously registered. Then, the efficiency of an extraction processing is improved, and the general words and the phrases which hardly come to the key words are prevented from being extracted. Furthermore, the extracted key word is held in the key word buffer 12. Thus, the key word included in given document data is automatically extracted without being designated as the key word at every input, and it can be used as the key word for generating the index of the document and for retrieving the document.

Title: Printing plate for flexure printing
Inventor: OZEKI MASANAO
IPC: B41N1/24
Filed: 1990-02-19
Abstract: PURPOSE:To avoid the generation of ink irregularity by preventing the distortion pattern due to the expansion and contraction of a printing plate by bonding a printing plate made of a synthetic resin and a mesh hard to deform in a plane direction and having the flexibility to bending to perform flexure printing. CONSTITUTION:In the mesh used in a printing plate for flexure printing, for example, woven crossings where metal wires are in contact with each other are bonded by plating. By this method, the metal wires of a node part are mutually bonded and, when tensile force is applied to the mesh in the plane direction thereof, it is prevented that the metal wires are mutually shifted at the woven crossings like a conventional fabric type mesh. An org. printing film is formed to the mesh thus formed hard to deform against the tensile force in the plane direction thereof by laminating a photosensitive film to the mesh by a laminator to perform pattern exposure, development and plate making. By this method, the mesh can be adapted to flexure printing while a synthetic resin film is used as the surface of the printing plate.
