Title: Clock distribution circuit
Inventor: AKATA MASAO
IPC: H03L7/22
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To assure an internal operation of a device when a switching instruction of a reference clock is given from the outside by using a limiting means which limits the highest phase varying speed to set the highest phase varying speed of a phase locked loop(PLL) circuit of every stage at a level higher than that of the PLL circuit of the preceding stage. SOLUTION: In a PLL 0 (12), a voltage controlled oscillator(VCO) input voltage limiting circuit 25 is placed between a loop filter 22 and a VCO 23. When the voltage-frequency characteristic of the VCO 23 used by the PLL 0 (12) is almost equal to that used by a PLL 1 (13), the VCO input voltage range of the PLL 0 (12) is limited by the input voltage limiting circuit 25. Thus, it is assured that the phase variance of the PLL 1 (13) is faster than that of the PLL 0 (12) even when the switching is performed between the clock sources 15 and 16 and the VCO input voltage has a large change. Thus, the circuit 25 can assure that the highest phase varying speed of a PLL of every stage is higher than that of the PLL of the preceding stage.

Title: Fiber type optical isolator
Inventor: SATO YASUSHI
IPC: G02B27/28
Filed: 1993-08-26
Abstract: PURPOSE:To provide an optical isolator which is small in size, low in cost and simple in constitution and has high versatility by impressing a magnetic field perpendicular to a progressing direction of light to a waveguide layer consisting of a magneto-optical material to generate non-reciprocity distribution coupling between an optical fiber and a non-reciprocity waveguide. CONSTITUTION:This fiber type optical isolator is constituted by removing a part of a clad 2 of an ordinary single mode optical fiber 1 for transmission formed by using an isotropic material, such as quartz glass, and loading the non-reciprocity waveguide 4 consisting of the magneto-optical material thereon. A waveguide layer 5 which is formed on the non-reciprocity waveguide 4 and varies in refractive index is similarly formed out of magneto-optical material. Reflection and scattering at the terminal of the non-reciprocity waveguide 4 are eliminated and the characteristics are improved if a light absorptive material 6 is mounted at the terminal. The magnetic field is impressed in the direction Y perpendicular to the progressing direction in order to generate a non-reciprocity phase shift in the non-reciprocity waveguide 4. The light propagating in the core 3 of the optical fiber 1 generates distribution coupling with the waveguide layer 5 in the part where the non-reciprocity waveguide 4 exists. The light power is thus transferred.

Filed: 1990-08-13
Abstract: PURPOSE:To prolong the service life of a driving means and to make the density of an obtained picture uniform by connecting a driving roller to a driving means via a heat insulation structure. CONSTITUTION:One end 41 of the driving roller 15 is protruded out of a heat development part 40. The heat development part 40 is a double-structure consisting of inside and outside frames 42 and 43. The inside frame 42 supports the driving roller 15, and the outside frame 43 is covered with a heat insulating material 46 which prevents the heat of the area 44 inside the heat development part 40 from being transferred to the area 45 outside the part 40, and vice versa.

A gear 50 is fitted to the one end of the driving roller 15 via a heat insulating member 49. Since the driving roller 15 is connected to a motor 16 via the heat insulation structure formed with the heat insulating member 49, the heat of a heat roller 12, which is required for heat development, is not transmitted to the motor 16, and long service life of the driving means and uniform image-density can be achieved.
