Title: Diamond semiconductor device.
Inventor: NISHIBAYASHI YOSHIKI C O ITAMI
IPC: H01L29/861
Filed: 1994-09-06
Abstract: A diamond semiconductor device of the present invention comprises an n-type diamond layer to which an n-type dopant is doped at high concentration so that metal conduction dominates, a p-type diamond layer to which a p-type dopant is doped at high concentration so that metal conduction dominates, and a high resistance diamond layer formed between the n-type diamond layer and the p-type diamond layer. Here, the thickness and the doping concentration of the high resistance diamond layer are values at which semiconductor conduction dominates. Then, in a case that an applied voltage is forward bias, electrons are injected from the n-type region to the p-type region through the conduction band of the high resistance region, and holes are injected from the p-type region to the n-type region through the valance band of the high resistance region, so that a current flows. On the other hand, in a case that an applied voltage is reverse bias because substantially no dopant is doped to the high resistance diamond layer, carriers are not present, so that a large current does not flow. Therefore, semiconductor conduction dominates as carrier conduction in pn junction and the rectification can be obtained, so that with the control of carriers, good diode characteristics or transistor characteristics can be achieved.

Abstract: A platesetting method and apparatus provides for dimensional and/or
exposure sensitivity changes in a printing plate (12) to be imaged in a
platesetter (10). A condition sensor senses the temperature of the plate (12)
prior to exposure so that a control unit (16) can adjust the control commands to
the scanning exposure mechanism (14) of the platesetter (10) in order to
compensate for any thermal expansion or exposure sensitivity shifts. An image
to be recorded onto the plate material (12) has a standard size at a standard plate
material temperature. When the plate material (12) is at a non-standard
temperature, as determined by the thermal sensor, a program, stored in
memory, calculates a new image size based on the non-standard temperature
and the thermal characteristics of the plate material (12) which are also stored
in memory. The imagesetter electronic controller (16) then exposes an image
having a size which will be the standard size when the plate material (12)
returns to the standard temperature.

Abstract: An apparatus and method for more accurately
determining the position of a moving object by using an
azimuth detector distinct from an angular speed detector
to correct the gain error and the offset error of the
angular speed detector. The position of the moving body
is determined using the offset error- and gain error-corrected
angular speed. The correction of the offset
error includes checking the azimuth and movement of the
moving object for three predetermined periods of time;
then checking whether the moving object was moving in a
straight line each of the three predetermined periods of
time. If the object was moving in a straight line each of
the three predetermined periods of time, then an offset
error correction value is computed using data from the
second of the three predetermined periods of time. The
correction of the gain error includes determining the
movement of the moving object as straight; then
determining the movement of the moving object as a turn;
then determining the movement of the moving object as
straight again. If the turn was a left turn, a left gain
error correction value is computed. similarly, if the
turn was a right turn, a right gain error correction value
is computed.
