  • Patent number: 8914211
    Abstract: A vehicle brake control device is configured to correct deformation failure of a seal member and inhibit insufficient pullback of a pressing member caused by insufficient deformation of the seal member. Within a time period from a start of a lock operation to an end of the release operation, a W/C pressure is automatically increased and insufficient deformation of a seal member is corrected. It is thus possible to generate a large restoring force by the seal member when pulling back a piston, and the piston can be pulled back based on the restoring force. The piston is therefore sufficiently moved, and it is possible to inhibit insufficient piston pullback. Further, it is possible to cause a brake pad to be separated from a brake disc by a predetermined distance, and it is possible to inhibit a feeling of drag of a brake from being imparted to a driver.

  • Patent number: 4217806
    Abstract: A read only memory is provided, which has a plurality of storing regions allotted for a plurality of kinds of rhythm patterns, each region having a plurality of addresses for storing, in an address sequence, a rhythm pattern of a shortest rhythm pattern unit represented by a combination of information units in the form of logic "ones" and logic "zeros", the logic "one"; representing a note being generated and the logic zero representing a note being not generated, whereby the notes are represented in binary form, whereby the required number of information units is reduced compared to the prior art. Each address in the memory has a plurality of bit positions allotted to a plurality of kinds of musical instruments, whereby a plurality of kinds of rhythm patterns are stored for a plurality of kinds of musical instruments.

  • Patent number: 4217805
    Abstract: A reference rhythm storing read only memory having a plurality of addresses for storing in advance, in an address sequence, information concerning a reference rhythm pattern and a writable/readable rhythm storing random access memory having addresses corresponding to the addresses of the reference rhythm storing memory for allowing for writing/reading information concerning a desired rhythm pattern unit are provided.
