Title: Phase-locked loop circuit
Inventor: AMASE KAZUHIKO
IPC: H03L7/00
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To simply correct phase locking with a small-sized, light-weight, low power consumption and a simple circuit configuration in the case of selecting a clock system in the communication system having a system changeover device that selects either of duplicate systems for a clock signal and a signal group synchronously with the clock signal to any time. SOLUTION: A phase-locked loop circuit 6 is constituted of a PLL 4 and memory 5. The PLL 4 adopts a narrow frequency range for its output clock 8 and a long receiving time of an input frequency signal, so that the output clock is synchronously with the input clock signal slowly to the utmost, when the input clock 7 whose period is instantaneously expanded or contracted is received. In the case of reading a signal, a signal outputted from a system changeover device 3 is read in a clock timing outputted from the system changeover device 3, and in the case of outputting a signal, the memory 5 used for the received signal is read by the output clock signal 8 synchronized with the clock signal which is outputted from the system changeover device 3 to the PLL 4.

Title: Magnetic-fluid sealing device
Inventor: NAKAZATO HIROSHI
IPC: F16J15/43
Filed: 1985-08-02
Abstract: PURPOSE:To prevent the generation of leaked magnetic flux of a magnetic fluid sealing mechanism due to the reduction of dimension by catching magnetic fluid between an annular pole piece for shielding the leaked magnetic flux and a shaft and between a permanent magnet and the shaft. CONSTITUTION:An annular pole piece 12 which possesses soft magnetism and has a section in L-figure form and a permanent magnet 13 magnetized in the radial direction are installed onto a shaft 11 which possesses soft magnetism, separated by a certain interval. Magnetic fluid 14 is magnetically caught in the part between the pole piece 12 and the shaft 11 and the part between the permanent magnet 13 and the shaft 11. Therefore, though a portion of the leaked magnetic flux of the permanent magnet 13 passes through the pole piece 12 and the rest leaks outside, the leak of magnetic flux outside the pole piece 12 side is prevented, since the pole piece 12 covers the permanent magnet 13 is the radial direction.
