Title: Data reproducing device
Inventor: HAYASHI NOBUHIRO
IPC: H03M13/23
Filed: 1992-05-11
Abstract: PURPOSE:To eliminate the need for a FIFO memory for correcting a time base and to simplify the constitution by using a code data storage memory as a time correction memory, as well, at the time of decoding for which the algorithm of wood is used. CONSTITUTION:A partial response class IV code is used as a modulation code and a Viterbi decoding method, sometimes, the decoding system of Wood is adopted as a decoding system. In such a state, a digital reproducing code is supplied directly to a decoding circuit 40 and a decoding processing is executed and also by a write clock WCK from a PLL circuit 20, decoding data are written in the memory of the decoding circuit 40 and by a read clock RCK in which time bases obtained from a clock generating circuit 21 are complete, the data are read. Thus, as for the decoding data, influence by an inter-code interference is eliminated and also its data become the data from which a jitter is eliminated. In such a manner, a time correction FIFO memory becomes unnecessary and the circuit configuration is simplified.

Title: Speed detector for brushless motor
Inventor: TSUCHIYA TOMONORI
IPC: H02P6/182
Filed: 1994-05-30
Abstract: PURPOSE:To reduce the lowest operating voltage of a motor by adding or subtracting the base potentials of first and second transistors in response to the variation of the base potential of a detecting transistor, and holding the base potentials of both transistors at the same potential. CONSTITUTION:When the base potential of a detecting transistor Q29, for example, rise and the base potential of the one (second) transistor Q25 of differential paired transistors 41 tends to become higher than that of the other (first) transistor Q24, the collector current of the transistor Q25 decreases, and it is observed that the collector currents of the transistor Q24 and transistors Q26, Q27 for constituting a current mirror circuit 42 increase. Thus, the base and emitter currents of an output transistor Q32 increase, the base potential of the transistor Q29 is reduced, and the base potential of the transistor Q25 is also lowered. Accordingly, the base potential of the transistor Q25 is held substantially the same as the base potential of the transistor Q24.

Filed: 1980-08-29
Abstract: PURPOSE:To enable the detection of a main magnetic flux density by a transformer by intimately contacting a Hall effect element covered with high magnetic permeability molding magnetic material at the periphery with the butted parts of magnetic cores. CONSTITUTION:A Hall effect element 3 is intimately contracted with the butted parts 5 of E-shaped and I-shaped magnetic cores 1, and the periphery of the element 3 is covered with a magnetic molding material mixed with high magnetic permeability magnetic powder, e.g., ferrite powder or the like in a synthetic resin. Since small air gap exists at the butted parts 5, a part phi3 of main magnetic flux phi0 is externally leaked, but since the magnetic molding material 4 has high magnetic permeability, the magnetic flux density of the magnetic flux phi2 passing through the Hall effect element 3 can be consequently increased. Thus, the Hall effect element 3 can detect the value near the original magnetic flux density of the magnetic cores 1 and can reduce the decrease in the detecting efficiency.
