Abstract: In a waste heat recovery device comprising a Rankine cycle in which working fluid circulates and a cooling circuit in which coolant water of an engine circulates, a heat source of a heater of the Rankine cycle is waste heat of the engine. A condenser of the Rankine cycle is configured to exchange heat between the working fluid and coolant water of a third coolant water circuit configured to circulate coolant water having passed through a radiator without passing through the engine.

Abstract: A magnetic tape cartridge includes a cartridge case, a pair of cylindrical hubs rotatably provided in the cartridge case, and a magnetic tape laid between the hubs and wound around outer peripheries of the hubs. Each of the hubs has an inner diameter portion provided with a height-position determining member. The height-position determining member determines a height position of the hub in the magnetic tape cartridge by contacting a driving shaft inserted in the hub when the magnetic tape cartridge is mounted in a magnetic recording and reproducing apparatus.

Abstract: The invention proposes a tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge.

Abstract: The present invention provides a tape drive apparatus enabled to directly and accurately detect dew condensation on a rotary head drum. Tape serving as a recording medium is drawn out of a cartridge. The drawn tape runs in such a way as to be wound on a tape takeup reel provided in a tape drive apparatus body. Signals are recorded on and reproduced from the tape by winding the drawn tape around the rotary head drum. This tape drive apparatus has a prethreading mechanism that brings the tape into slight contact with the rotary head drum before the tape is completely wound therearound. Dew condensation on the rotary head drum is detected by rotating the rotary head drum during a status in which the tape is brought by the prethreading mechanism into contact with the rotary head drum.

Abstract: A tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge. The apparatus includes a carrying mechanism for extracting the tape as a recording medium from the cartridge where the magnetic tape is stored, and for carrying the magnetic tape to be wound up onto a takeup reel provided on the drive apparatus.

Abstract: There is provided a recording and/or reproducing apparatus including: a cartridge loading member into which is loaded a tape cartridge having a magnetic tape provided with a leader block on one end; a take-up mechanism for winding the magnetic tape; a carrying mechanism for carrying a tape pulling member, which engages with the leader block and pulls the magnetic tape from the tape cartridge, between the tape cartridge and the take-up mechanism; and a magnetic head mechanism for recording or reproducing signals. An area in which the cartridge loading member is formed, and an area in which the take-up mechanism, the carrying mechanism and the magnetic head mechanism are formed are divided by a partition, and the partition has an opening, and a shutter mechanism for shutting the opening. Thus, a recording and/or reproducing apparatus capable of preventing dust and the like from entering into the drive area is provided.

Abstract: A single-reel tape cartridge includes a leader block and a take-up reel disposed inside a drive apparatus that are provided with retaining members so that the leader block is firmly positioned and rattling thereof is prevented. A pair of changer grips which extend from end to end of a housing of the cartridge in the vertical direction are formed at two corners of the cartridge housing. In addition, a memory module, which stores the management information for the tape-like recording medium and which is used for radio communication, is disposed at an angle in one of the corners of the cartridge so that a communication antenna of the memory module faces at least two directions. In addition, the leader tape is provided with a striped portion used for identifying the medium, and the cartridge housing is closed by a shutter used for disengaging the reel lock.

Abstract: A tape drive uses a single-reel type tape cassette, and includes a pull-back guide shaft for pulling back a tape-shaped recording medium at a predetermined position and a pair of moveable guide pins, whereby the tape-shaped recording medium is positioned between the paired guide pins is wound around the drum. A tension device applies a predetermined tension when the tape-shaped recording medium has been drawn out and a tape path has been formed. A non-winding fast feed mode is set in which the tape-shaped recording medium is fed at high speed under a predetermined tension wherein the tape-shaped recording medium is not wound around the drum. The tension device has a tension regulator lever having two guide shafts for both winding feed mode and non-winding feed mode.

Abstract: A tape cartridge housing a magnetic tape includes an auxiliary storage medium having a storage unit in which to store the recording medium information such as design parameters or the number of times of recording and/or reproduction of the magnetic tape, and a transmission/reception unit for effecting inputting/outputting of the recording medium information with the recording and/or reproducing apparatus. The auxiliary storage medium is mounted so that the transmission/reception unit is exposed to the outside through an opening provided in a lateral surface of the main cartridge body unit not obstructing the loading of the magnetic tape, that is in a surface of the main cartridge body unit other than its front surface as an inserting end of the tape cartridge into the inside of the recording and/or reproducing apparatus.

Abstract: A tape cassette includes an MIC (Memory-In-Cassette) installed inside the center section of the label surface, and a case capable of housing the magnetic tape. A switch circuit board is installed in the front part of the chassis parallel to the inner side of the front panel, and a communications antenna is mounted on this switch circuit board. When the cassette is loaded in the chassis from the cassette insertion slot, the MIC is in proximity to the front of the communications antenna and wireless communications between the antenna and MIC are carried out with high accuracy. By efficiently installing an MIC in a tape cassette having little excess space such as DAT (digital audio tape recorder) cassettes, an increase in the number of parts and the number of assembly processes can be avoided and highly accurate reading and writing of control information on the MIC in the cassette can be performed.

Abstract: When a memory in cassette (MIC) in a loaded tape cassette can successfully be accessed, an MIC type stored in the MIC is detected to judge a data format the tape cassette has. To this end, the tape cassette is adapted such that the data format or the loaded tape cassette can be identified without detecting an identification hole formed in the tape cassette. Thus, it is possible to easily accommodate any future extension of the data format.
