摘要:
A clock extracting circuit for receiving an encoded signal and for extracting a clock signal from the encoded signal. The circuit comprises an edge detector that detects rising and falling edges of the encoded signal and produces edge detection pulses indicating the edges being detected; a mask signal generator producing a mask signal which is inverted in response to the edge detection pulses, which are produced one for each period of the received encoded signal, on the basis of the edge detection pulses; a mask signal delay section delaying the mask signal by a delay time controllable and outputting the delayed mask signal; a clock generator producing the clock signal on the basis of edges of the delayed mask signal; and a delay controller that controls the delay time of the mask signal delay section so as to set a duty ratio of the produced clock signal to a predetermined value.

A suspension of a sparingly water-soluble acidic drug, especially, a nonsteroidal anti-inflammatory analgesic agent, which is stable for a prolonged period of time and is highly dissolvable, and a process for simply and easily producing the suspension. This suspension has a pH value of 2 to 5 and comprises a sparingly water-soluble acidic drug whose average particle size ranges from 1 to 15 &mgr;m, a polyglycerol fatty acid ester, a water-soluble polyhydric alcohol and water, optionally, together with an inorganic powder having an average particle size of 1 to 15 &mgr;m. This process is characterized by carrying out pulverization and dispersion of a sparingly water-soluble acid drug, a polyglycerol fatty acid ester, a water-soluble polyhydric alcohol and water by means of a pulverizer comprising a main shaft adapted to rotate in a casing and a plurality of layshafts adapted to revolve in relationship interlocked with the rotation of the main shaft, each of the layshafts being fitted with a multiplicity of annular griding media.
摘要:
This invention provides a small-sized and easy assembling head positioning apparatus having a coarse moving mechanism and fine moving mechanism, by which the desired fine moving accuracy is easy to attain. A head positioning apparatus has a first stepping motor, a lead screw, and a cylindrical rack for coarse moving. The cylindrical rack is formed by rotating a rack around the axis of the lead screw and is provided with the lead screw. The head positioning apparatus has a second stepping notor and gears for reducing the speed of the rotation of the second stepping motor for fine moving means, and fine moving is carried out by moving the cylindrical rack by the gear. The lead screw is provided so that the first stepping motor could be moved in a X1, X2 direction in the fixed moving range.

摘要:
A flexible disk unit having a reduced thickness includes a spindle motor for rotating a magnetic recording medium having a magnet at its outer periphery, a movable carriage supporting a magnetic head and a stator surrounding the spindle motor and including a coil opposed to the magnet. The stator has a recess which is adapted to surround the tip of the movable carriage when the carriage is moved towards the magnetic recording medium. A head shield portion is disposed between the stator and the magnetic for shielding leakage flux in the direction of the magnetic head.

摘要:
A bar code reader includes a line sensor having a scanning range large enough to scan two or more bar codes. A portion of the scanning range having a size corresponding to a single bar code is determined as a reading range. A reading range comparator 35 determines when a bar code is positioned within the reading range, so that no other bar code within the scanning range will be read. The reader also has error detection to determine whether counted numbers of bars fall within a permissible range for a given bar code symbology.
