  • Patent number: 5743111
    Abstract: A heat exchanger, as mounted on the outdoor unit or indoor unit of an air conditioner system, is formed with a plurality of passages for a refrigerant. To this heat exchanger, there is connected a refrigerant distributor for distributing the refrigerant to the individual passages or for collecting the distributed refrigerant. This refrigerant distributor is constructed by soldering two corrugated plate members to form a refrigerant conduit between the corrugations. Before these plate members are soldered, the refrigerant conduit is either partially constricted to form a throttle portion or partially bulged to form a filter portion by fitting a filter member in the bulging portion when the plate members are soldered. Thus, the refrigerant distributor can set the diversion of the refrigerant to a predetermined ratio by the simple device while reducing the space and lowering the cost.

  • Patent number: 5685654
    Abstract: A tape storage cassette contains a thermal transfer ribbon having an ink coating on one surface and a recording tape wound about respective spools. A separator concentric with the recording tape spool wraps partially about the recording tape wound upon the spool to isolate the recording tape from the ink coating on the thermal transfer ribbon and cooperates with a film separator in preventing contact between the transfer ribbon and recording film prior to printing.

  • Patent number: 5296084
    Abstract: In a tape alignment mechanism for overlapping two or more tapes with an alignment operation in a width direction, the tape alignment mechanism comprises an alignment member.For example, when a tape is fed through a roller member having a pair of flange portion of which interval of length is designed to be substantially similar to a width of the tape, the tape is aligned in a width direction.Further, an another tape to be overlapped with the tape is fed through the roller member, and thus, the two tapes are acculately overlapped.

  • Patent number: 5188469
    Abstract: In a tape feed mechanism comprising a tape storage cassette including at least two tapes in respective wound states and a tape feed device feeding the two tapes in an overlapped state, provided is a guide member for guiding the two tapes to a predetermined portion in the tape storage cassette. Thus, the tape storage cassette is detachably mounted from the tape feed device in a condition that each of the leading end portions of the tapes are fixed at the predetermined position and the tape storage cassette is attachably mounted again to the tape feed device in that condition.
