IPC: G11B7/09
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To optimize timing for sampling a tracking error signal when a mirror surface is reproduced. SOLUTION: An RF signal is inputted to a level shift circuit 40, and a DC level is shifted by a prescribed amt., and also the signal is invertibly amplified with a prescribed gain, and is outputted to a bottom hold circuit 41. A bottom of an envelope of the signal outputted from the level shift circuit 40 is extracted by the bottom hold circuit 41, and is outputted to a threshold circuit 42. When an output of the bottom hold circuit 41 exceeds a threshold level, this output is turned into the state of 'H' by the threshold circuit 42. When the output of the threshold circuit 42 is in the state of 'H', a semiconductor switch 43 is turned into the on-state, and hence a terminal A is grounded, and then an output from a mirror detecting circuit 47 is masked.

Abstract: PROBLEM TO BE SOLVED: To prevent a potential difference between a source and a channel from being increased to make it possible to enhance the breakdown voltage of a field-effect transistor by a method wherein an impurity layer for capturing holes, which are generated in a drain region, is formed in a conductive layer under the channel region of the transistor. SOLUTION: In order to realize the enhancement of the breakdown voltage of a field-effect transistor by preventing a potential difference between a source and a channel from being increased, carriers, which are secondarily generated, are dispersed evenly in the whole lower part of the channel so as not to collect in the vicinity of the source. Owing to that, impurities, which work as a trap to holes, are introduced in the lower part of the channel and the holes are inhibited from moving to the vicinity of the source. Electrons generated in a high electric field in the vicinity of a drain are drawn out in the drain by the electric field in the vicinity of the drain, the holes are captured by a trap layer 6, which is formed of an Fe layer, under the lower part of the channel and are moved to the source side slowly in comparison and a current due to an injection of the holes from the channel side to the source can he reduced.

Filed: 1989-12-29
Abstract: PURPOSE: To relieve the opposed force in a holder drive mechanism by storing the potential energy when the respective cross arms are turned in the first rotational direction and comprising an auxiliary force member to feed energy to an X-ray inspecting device when the cross arms are turned in the second rotational direction. CONSTITUTION: Tension spring 38 is provided between mounting portions 34, 36 of the device. The connecting line running between the mounting portions 34, 36 crosses a turning axis 40. Fitting the spring while being tensioned is place results in increasing the tension and displacing side arms 20, 22 in the direction 42 when cross arms 16, 18 rotate. The tension forms a moment centering around rotating axis 40 which goes up as the turning speeds of cross arms 16, 18 are accelerated. Turning cross arms 16, 18 in the opposite direction coincides with moving side arms 20, 22 in the opposite direction to the direction 42 but due to said moment present at this stage, a lesser external force is sufficient for this opposite directional rotation.  Spring-originated working force is optimized over a range of adjustment by way of selectively vary distance between the mounting portion 34 and rotating axis 40, and via adjusting the pressure or the tension of spring 38.
