摘要:
A magnetic tape cassette, such as a high performance video cassette, having a greatly improved dust-proofing function. In a first embodiment, operating portions of brake members which engage a brake release lever which is inserted into the cassette at the time of recording or reproduction to release the braking system of the cassette are formed in an inverted cup shape so as to close the hole through which the brake release lever is inserted and to contain the end of the brake release lever when inserted into the hole. In a second embodiment, separate engagement and abutment portions are provided for each brake portion so as to prevent inadvertent opening of the hole if the tape reels are moved during storage. In a third embodiment, the dust-blocking member takes the form of a slitted flexible sheet member covering the hole when the cassette is not in use.

The recording medium cartridge includes a cartridge case containing a recording medium and a noncontact-type memory having an IC section for storing information and performing signal processing and an antenna section for transmitting and receiving signals. The antenna section of the memory is placed in a region furthest from metallic parts.

The recording medium cartridge includes a cartridge case containing a recording medium and a noncontact-type memory having an IC section for storing information and performing signal processing and an antenna section for transmitting and receiving signals. In one cartridge, the antenna section of the memory is placed in a region furtherest from metallic parts. In other cartridge, the memory is mounted in an accommodation portion recessed one step relative to a surrounding portion, in such a way that a portion of an inner wall of a real area for accommodating a magnetic tape corresponding to the recording medium is formed, in such a position as to be exposed when the cartridge is loaded into a drive, or in recess formed in an outer surface of a case. The cartridge label is attached to the cartridge and contains the noncontact-type memory. At least an antenna section protective indication for indicating an information writing area other than the area on an antenna coil of the antenna section is provided on the cartridge label.

An inner fin is an offset fin having a wavy cross-section that is perpendicular to an oil flowing direction, and has a louver that is partially cut and bent in a direction parallel with the oil flowing direction. The wavy cross-section is defined by alternately placing first-side convex parts and second-side convex parts. A fin height fh is defined by a distance from the first-side convex part to the second-side convex part in the cross-section. An area surrounded by the inner fin, a tube, and the first-side or second-side convex parts located adjacent with each other on the same side in the cross-section is converted into a corresponding circle having a diameter de. When a relationship of X=de/fh0.3 is defined, the diameter of the corresponding circle and the fin height respectively have dimensions that satisfy a relationship of 0.5≦X≦1.0.

In a RAM 1-3, a data area and a current memory are provided. A signal processing portion 1-10 processes audio signals in accordance with a parameter set stored in the current memory. In the data area, a plurality of S data sets each formed of a parameter set and an S list which is a list of S data sets are stored. Each S data set is identified by its unique identification information (SID). The S list stores list information including SIDs which identify the respective S data sets. When storage of the parameter set stored in the current memory is desired, a new SID is generated, so that list information including the generated SID is added to the S list, with the SID being added to the parameter set of the current memory to be stored as a new S data set in the data area.
摘要:
When a controlled device has changed the value of a parameter, the controlled device transmits the result of the change as updated information UPDATE to controllers by multicast, and aside from this, also transmits synchronization data SYNC in each synchronization period by multicast. Upon detecting a reception error of those data, the controller requests, from the controlled device, the information of the parameter which has been changed in one or more synchronization periods including and after the synchronization period subsequent to the last synchronization period in which the controller could normally receive all of the packets, and corrects the parameter value in the controller based on the current value of the changed parameter transmitted from the controlled device in response to the request.
