Title: Tracking servo device
Inventor: KUBO JUNICHI
IPC: G11B7/085
Filed: 1988-07-22
Abstract: PURPOSE:To shorten a tracking servo leading-in time by executing prescribed correspondent processing on the basis of a change in a necessary condition. CONSTITUTION:The determined condition change is detected from a tracking error signal in each area from the outer circumference to inner circumference of a disk. Then, as the condition change, there are the change from an on-track condition to an off-track condition, the change from the off-track condition to the on-track condition and whether a tracking error signal is not less than a prescribed value or not more than the prescribed value, etc. The correspondent processing is executed in correspondence to this condition change. Then, when the processing to correspond to the tracking error signal is executed at the time of track cross, for example, when power is added to a pick-up lens reversely to a direction that the pick-up lens is moved to a track, etc., the tracking servo leading-in time can be shortened.

Title: Radiation detector
Inventor: YOSHIDA YUZO
IPC: G01N23/04
Filed: 1987-07-24
Abstract: PURPOSE:To obtain an inexpensive detector which necessitates no movable mechanism, and also, can obtain desired slice thickness, by a simple constitution, by extracting selectively an output of a split electrode part of a position corresponding to width of a necessary radiation detecting visual field. CONSTITUTION:From a confronted X-ray source XT, fan beam X rays XB having a prescribed expanse are radiated with prescribed thickness. This fan beam X rays XB transmit through a body to be inspected P and go into a radiation detector, but since there is no mechanism for reducing variably the beam thickness of the fan beam X rays XB, the fan beam X rays XB of the same beam thickness arrive at any time. Therefore, as for a radiation detecting cell of the radiation detector, X rays are always made incident on the whole cell, but since a collecting electrode 12 of the cell is constituted of split electrode parts 12b-12d being independent, respectively, the split electrode part which can extract a detecting signal 1 is determined by turning on switches 14a-14c, by which the beam thickness detected substantially is determined.
