摘要:
An optical information recording medium includes a plurality of rows of tracking tracks arranged at intervals, a plurality of recording portions provided between the tracking tracks and on which information is recorded by application of a light beam thereto, and an optically detectable mark provided at at least one location on at least one of the recording portions. The recording surface of the recording medium is divided into a recording area and a non-recording area in a direction perpendicular to direction of the plurality of rows of the tracking tracks. The optically detectable mark represents a boundary of the recording area and the non-recording area.

Disclosed is an intermediate frequency circuit of a digital television tuner having a flat transmission characteristic in an intermediate frequency band and in which a transistor is prevented from being destroyed by a shock wave such as static electricity applied on the output side. This intermediate frequency circuit has: a transistor for amplifying a television signal in an intermediate frequency band; a low-pass filter provided between a collector of the transistor and an output terminal; and a parallel tuning circuit provided between the collector of the transistor and the ground. Each of a cut-off frequency of the low-pass filter and a tuning frequency of the parallel tuning circuit is set to be equal to or higher than the intermediate frequency band.

An information reproducing apparatus for reproducing recorded data includes a buffer, a control device and a determining device. The buffer stores data blocks read out from a recording medium and includes first and second storage areas having respectively discontinuous storing and read addresses. The apparatus is controlled to execute in parallel a first process for storing the data blocks into the buffer and a second process for reading out the data blocks stored in the buffer to transfer the data blocks to a host apparatus. The determining device determines whether there are data in the first storage area to be transferred to the host apparatus by comparing a storing address in the buffer of the data which are being stored into the first storage area with a read address in the buffer of the data which are being read out from the first storage area. The first process is controlled so that a predetermined data block which has been read out from the recording medium is stored into the second storage area. When the predetermined data block is stored into the second storage area, the determining device does not compare the storing address in the buffer of the data which are being stored into the second storage area with the read address in the buffer of the data which are being read out from the buffer.
摘要:
vibration insulator is provided which includes a vibration insulator section having an outer cylinder, a rubber member which is vulcanization-bonded to the inner peripheral surface of the outer cylinder and an inner cylinder supported by the rubber member, and a bracket for supporting the vibration insulator section, with the thickness of the bracket material being made as small as possible. The bracket is composed of a pair of sheet-metal bracket members holding the axial ends of the vibration insulator. The bracket members include plate-like base sections axially opposed to each other, cylindrical sections which extend axially outward from the base sections and into which the end portions of the outer cylinder are forced, abutting sections extending radially inward from the end edges of the cylindrical sections and abutting the end surfaces of the outer cylinder and joint sections joining the bracket members to each other. A method of manufacturing the vibration insulator bracket is also provided.

There is disclosed an information recording medium having an area for recording data and an area for recording a directory used to manage the recorded data, by providing an area for recording information indicating logical erasure of the unnecessary data. In the information record method of the present invention, when unnecessary data is produced, information indicating the logical erasure of the data is recorded in the area of the information record medium in which the directory is recorded.
