Title: Error designatable magneto-optical disk device
Inventor: OGAWA HIDETAKA
IPC: G11B19/04
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To efficiently and satisfactorily appraise an abnormal system of a device driver by arbitrarily generating an abnormal state in a disk controller and the whole device. SOLUTION: An error number desired to be generated is selected and inputted to a processing input part 1 by the user. Processing contents are decided by a processing analysis part 2 based on the number selected and inputted by the user, and the contents are stored in the most rear part of a processing table 3. The processing table 3 is always monitored by an information transmitting part 4 to output a result of taking out processing contents as an error by moving up the next processing contents step by setp to a personal computer 200. When an error such as time-out without a response, etc., is desired to be generated, processing is performed in similar procedure to the above, but only procedure in a processing control part 5 is different as the output of the result to the personal computer 200 is not performed by the processing control part 5 to keep on the state until a restoring instruction is given.

Abstract: PURPOSE: To provide a brightness controlling apparatus, in which conduction phase angle of a switching element is controlled according to the voltage across a capacitor that is connected between the gate and the source of a field-effect transistor, whereby brightness of the lamp can be controlled at a plurality of places, only through additional provision of a control switch.  
     CONSTITUTION: When changeover switch 5 is connected to the side of terminal (a), capacitor C 1  is charged depending on the potential of capacitor C 2 , thereby increasing the voltage across the capacitor C 1 , and a field-effect transistor FET conducts depending on the voltage across capacitor C 1 . By this conduction of transistor FET, firing period of firing element 6 is changed and conduction phase angle of switching element 2 is changed from small to large, whereby output of light is changed from dark to bright. When switching control is stopped at the point where a proper brightness is obtained, change-over switch 5 is turned OFF since it is constituted by a non-locking switch. Thus, potential of capacitor C 1  is maintained and conduction angle of switching element 2 is kept at a fixed angle.
