Abstract: A laser diode 11 performs switching operation with a high speed in response
to a digital-modulated electric signal inputted in differential input terminals 10a and
10b. At this time, a voltage detecting portion 14 detects a terminal voltage of the
laser diode 11. A peak detecting portion 15 detects a peak value of output of the
voltage detecting portion 14. A current control portion 16 controls a drive current
of the laser diode 11 in accordance with output of the peak detecting portion 15.
The current control portion 16 includes a reference voltage generating portion 16a
generating reference voltage, and an error detecting portion 16b detecting an error
between the reference voltage generated by the reference voltage generating
portion 16a and the output of the peak detecting portion 15. In accordance with an
output signal of the error detecting portion 16b, the drive current of the laser diode
11 is controlled. In this way, it is possible to stabilize light output of the laser diode
11 without using a photodiode for monitoring, and thereby to obtain a light emitting
device drive circuit with high reliability at low costs. Further, since the current
control portion 16 is divided into the reference voltage generating portion and the
error detecting portion, required is to change only the reference voltage generating
portion 16a when a light emitting device of a different type is used. Further, the
reference voltage generating portion 16a generates reference voltage which follows
changes of the terminal voltage of the laser diode 11 with respect to temperature
changes under the conditions that light output of the laser diode 11 is kept
constant, and thereby it is possible to obtain constant light output in a wide range
of temperatures.

Abstract: The invention concerns a smectic liquid crystal element and method of
manufacture thereof. A polymer having spontaneous polarization as the liquid crystal is
introduced into a liquid crystal layer of the smectic liquid crystal element in order to
improve the response speed (second liquid crystal cell). The polymer has the same
codes as the liquid crystal. Alternatively, a polymer having spontaneous polarization
with opposite codes to the liquid crystal is introduced into a liquid crystal having a
τ - V min  characteristic so that a driving voltage is lowered (first liquid crystal cell).
These polymers are added to a liquid crystal composite before injection into the liquid
crystal cell. In a further aspect, after a photochemically polymeric monomer is added to
the liquid crystal composite and the obtained product is injected into the liquid crystal
cell, the monomer is polymerized by the application of light. Furthermore, the liquid
crystal cell into which the polymer is introduced is heated again so as to exhibit
isotropic phase and is cooled so that the tone display is realized.

calling into the system, the user terminal pages earth
stations in descending order of score in the league
table. When in contact, the user terminal 11 sends the
league table to the system. When subsequently trying to
contact the user terminal 11, the system uses earth
stations in descending order of score in the league
table, last received from the user terminal.

Abstract: A method of filtering images with a filter that is dependent on image type. For
binary images, a fixed Laplacian filter is used (202) for all pixels. For non-binary images,
an automatic level-sensitive Laplacian filter is used (206, 208). For non-binary images,
Laplacian filter coefficients and normalization divisors are made a function of intensity on a
pixel by pixel basis. Pixels indicating a high intensity may be greatly changed by
neighboring pixels. Pixels indicating a low intensity receive relatively little or no filtering.
In a specific example embodiment, the intensity range is divided to bands, with a different
filter for each band. The resulting images are visually sharpened (edge enhanced) with very
little impact in darker areas of the image.
