Abstract: An element for specifying the condition and type of immune-related diseases on the basis of the knowledge about the polarization of distribution of Th1/Th2 subsets of helper T cells. The element for specifying or correcting the polarization of the Th1/Th2 subsets is implemented by use of a recombinant vector, a transformant, a human-Th1-specific protein, and an antibody which uses the human-Th1-specific protein as an antigen. A human-Th1-specific gene is prepared and specified by a subtraction technique and is incorporated into the recombinant vector. The transformant is formed by transforming the recombinant vector. The Th1-specific protein is encoded by the gene derived from the transformant.

Abstract: A recording medium cartridge includes a memory circuit for storing information concerning signals recorded on the recording medium within the cartridge. The information is stored in the memory circuit in the form of a hierarchic data structure which includes a plurality of data packets having a predetermined form and length. Each data packet includes a code indicative of a level in the data structure to which the data packet belongs. At least some of the data packets include data indicative of starting and ending positions on the recording medium of recorded signals which the data packet represents. The hierarchic (or "tree") data structure facilitates rapid retrieval and reproduction of the signals recorded on the recording medium, particularly when the recording medium is a magnetic tape. The tree structure also facilitates storage of information in connection with recording of additional signals on the recording medium.

Abstract: A recorded data securing mechanism secures data recorded on a recording medium cassette provided with a memory and a data recording enable/disable tab at a predetermined position on the cassette. Breaking the recording enable/disable tab provided on the memory-based recording medium cassette prevents data recorded on the cassette from being written over and ensures that there will be no mismatch between the recording information stored in the memory of the cassette and the data recorded on the recording medium of the cassette. In one embodiment, rewriting is enabled but a memory mismatch flag is set if rewriting results in a mismatch.

On the other hand, on the recording unit side, after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit of transmission, the digital video signal is provided with a parity for recording by a parity generator and is then recorded in a recording medium.

Abstract: A signal recording and/or reproducing apparatus, such as a video tape recorder or the like, records and/or reproduces an information signal indicating a date of recording, a video signal and a PCM signal from a helical track on a record medium, such as a magnetic tape. The track has first and second portions which respectively record the PCM signal and the video signal. In certain advantageous embodiments, the information signal is recorded in a guard band area between the first and second portions of the track. The apparatus has the capability of selectively superimposing the date information on the video signal for display. A record medium in which a plurality of such helical tracks are formed may be searched to locate signals recorded on a selected date, thus providing a convenient search capability which is implemented in a simple and straightforward manner.

Abstract: A VTR incorporating a video printing controller comprising at least one rotary magnetic head for scanning recording tracks formed on a magnetic tape to reproduce a video signal recorded on a recording track specified by a marker signal, a marker signal detector for detecting the marker signal specifying the recording track carrying the video signal to be printed, and a system controller connected to the marker signal detector and to a video printer connected to the VTR. The system controller gives a video printer control signal to the video printer upon receipt of a marker signal detection signal from the marker signal detector to control the video printer for printing out in a hard copy the video image reproduced from the recording track specified by the marker signal. Thus, the recording track storing the video image desired to be printed is located automatically by searching the recording tracks for the marker signal, and then the desired video signal is printed out automatically.

Abstract: A gas reaction apparatus has an activation chamber, a heat exchanger and a reaction chamber. A gas is introduced into the activation chamber and activated there by electric discharge. The activated gas is then cooled by the heat exchanger in case a reaction to be effected in the reaction chamber is exothermic or heated by the exchanger in case a reaction to be effected in the reaction chamber is endothermic. The heat resulting from the reaction with the gas can therefore be effectively removed so that a desired reaction is rapidly conducted in the reaction chamber without being followed by a side reaction.
