Abstract: A pulse radar apparatus uses different frequencies, for example, frequencies one of which is a multiple or a submultiple of the other for a signal which becomes a reference of a control pulse for controlling a gate operation for a reception signal and a signal which becomes a base of generation of a transmission pulse. As a result, even if noise is caused by the gate operation, its influence can be removed in the processing of reception signals having different frequencies.

Abstract: Provided is a method for enhancing the activity of a protein, which protein when mutated, folds in an incorrect conformation in the endoplasmic reticulum, by contacting the protein with an effective amount compound which specifically binds to the protein and induces the protein to fold into a proper conformation (a specific chaperone). Also provided are methods for enhancing the stability and preventing the degradation of a protein by contacting the protein with an effective amount of a specific chaperone for the protein which stabilizes the protein in a proper conformation.

Abstract: Embodiments of the invention reduce the noise occurring when the lubricating layer on the magnetic disk is smoothed. In one embodiment, a magnetic disk drive has a read/write mode parameter table for generating an electric current to be supplied to a voice coil motor when the magnetic head performs data read/write operations on the magnetic disk. The magnetic disk drive also has a smoothing mode parameter table for generating another electric current to be supplied to the voice coil motor when neither a data read nor a write operation is performed on the magnetic disk. The CPU refers to either the read/write mode parameter table or the smoothing mode parameter table and controls the electric current to be supplied to the voice coil motor.

Abstract: Embodiments of the invention perform a stable data write operation at a low operating ambient temperature and promptly perform a write command process within a magnetic recording apparatus that employs a load/unload design. In one embodiment, write heads unloaded on a ramp are completely preheated before magnetic disks reach their rated rotation speed. This preheat operation takes time T1. After completion of write head preheating, the write heads are loaded from the ramp. This loading operation takes time T2. Since time T1 and time T2 do not sequentially elapse, it is possible to prevent a write operation from being rendered unstable by thermal protrusion while expediting a write command process.

Abstract: In the WDM optical transmission, optical signals propagated through an optical transmission line are supplied to a circulator of a wavelength dispersion compensator. The optical signals supplied to an input terminal of the circulator are transmitted to an input and output terminal of the circulator, and inputted to fiber gratings of the reflection type. The optical signals having a specified wavelength is reflected by one of the fiber gratings, again inputted to the input and output terminal of the circulator, and transmitted to the output terminal of the same. Since the incident optical signals are reflected by the fiber gratings situated at different positions, there arises the difference in the time spent in traveling to and from the fiber grating between the optical signals. Accordingly, the wavelength dispersions of the optical signals can be compensated by suitably selecting the positions of the fiber gratings.

Abstract: Embodiments of the invention are directed to detecting an abnormality in head flying height. In one embodiment, an AGC controller establishes the gain of the reproduced signal through gain adjustment using the servo AGC of the servo signal. A digital filter performs filtering processing by use of the obtained gain data g and the gain data of previous sectors. A comparative judgment section obtains filtered gain data G from the digital filter and compares the gain data G with a reference value CRITERIA to determine whether the flying height is normal or abnormal. If the gain G is larger than the reference value CRITERIA, then the data write operation is inhibited. The filter parameters of the digital filter are programmable parameters which can be set and changed.

Abstract: A signal from CW radar is received, and the received power detected by the CW radar's swinging in all directions is averaged in each direction. Then, the maximum value and the minimum value of the received power are detected for each direction, and the difference between the maximum value and the minimum value is computed. An average power value of obtained power is also computed. On a 2-dimensional plane on which the difference between the maximum value and the minimum value and the average power value are used for coordinate axes, slice processing is performed using a threshold indicated by a line graph or a curve.
