Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit such as a semiconductor memory with a selection circuit which enables the reduction of a power consumption by eliminating a through-current. SOLUTION: By cutting off a fuse 33 in an enable signal setting unit 30, the level of an enable signal EN is turned to 'H'.

Title: Servo controller
Inventor: HOSOI KAZUO
IPC: H02P29/00
Filed: 1981-10-19
Abstract: PURPOSE:To prevent the variation in the torque of a motor by controlling the drive current of the motor in response to the output level of a photoencoder, thereby utilizing the variation in the characteristics due to the magnet of the motor and the temperature of the photoencoder. CONSTITUTION:A photoencoder 15 having a disc 2, a light emitting element 3 and a photodetector 4 is mounted on a shaft 1 of a motor 14 used for a printer or the like, its signal is inputted to a reference voltage generator 16, is transmitted to a main amplifier 13, thereby controlling the current of the motor 14. Accordingly, when a servo controller is used continuously for a long period of time so that the motor temperature rises, it is transmitted to a photoencoder 15, and the output level is varied due to the difference of the thermal expansions of the respective sections. Accordingly, the variation in the torque of the motor 14 can be prevented from the correlation between the variations in the magnetic characteristic due to the variation in the temperature of a ferrite magnet of the motor 14 and the output characteristics of the photoencoder 15.

Title: Polarized wave mode dispersion compensating device
Inventor: TANAKA HIDEAKI
IPC: H04B10/2507
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To compensate the polarized wave mode dispersion of an input signal light by adapting to the state of the polarization of the signal light. SOLUTION: A signal light from an optical transmission line is inputted to as polarization converting device 12 by propagating an optical fiber 10. The device 12 converts the input light having an arbitrary polarized wave into linearly polarized waves having a prescribed angle by the quater-wave plate between two Faraday rotators. The output light of the device 12 inputs to a polarizing beam splitter 16 by propagating through an optical fiber 14. The beam splitter 16 outputs one side (for example, a TE component) of two orthogonal polarized wave components (for example, TE and TM components) from the fiber 14 to an optical fiber 18. A part of the light propagating through the fiber 18 is branched by an optical coupler 22 to be made incident on a light receiving element 24. A band-pass filter(BPF) 26 extracts the clock component of the signal from the output of the element 24.  A control circuit 28 controls the angle of the polarized wave of the output light by the device 12 so that output of the BPF 26 becomes the maximum according to the output of the filter 26.
