Title: Optical disk drive apparatus having counter disable at seek start-up
Inventor: NAKATSU KEIJI
IPC: G11B21/08
Filed: 1988-03-16
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE       In an optical disk drive apparatus for driving an optical disk having tracks for recording information, an optical head focuses a light beam onto a spot on a track on the optical disk, and an actuator moves the optical head, thereby causing the spot of the light beam to move from its current track to a target track in order to access the target track. A track counter counts the tracks moved by the spot of the light beam. The counting of tracks is disabled for an interval at the start of each track access operation  to prevent miscounting caused by jitter that occurs when initiating a track access operation.

Filed: 1988-05-24
Granted: 1992-01-14
Abstract: Un contrôleur électronique comporte deux bornes d'entrée entre lesquelles le secteur et une charge électrique sont reliés en série. Une unité de traitement génère un signal de commande d'application de puissance électrique à la charge qui ferme un commutateur électronique également relié entre les deux bornes d'entrée pour interconnecter le secteur et la charge en série dans une boucle fermée. Une tension électrique d'alimentation du contrôleur est fournie par une seconde source dérivée des deux bornes d'entrée, donc du secteur à travers la charge lorsque le commutateur est ouvert. Un circuit électronique ouvre en présence du signal de commande, le commutateur normalement fermé par ce signal afin de maintenir à un niveau adéquat la tension d'alimentation du contrôleur. L'ouverture du commutateur se produit temporairement et de façon répétée, soit périodiquement, soit lorsque la tension d'alimentation du contrôleur passe en dessous d'une valeur seuil prédéterminée.

Filed: 1988-09-02
Granted: 1992-09-22
Abstract: ABSTRACT       A  data  processing  system  includes  a  number  of subsystems coupled in common to a system bus.  The subsystems communicate with each other by sending commands to each other via  the  system  bus.    Channel  numbers  identify  the subsystems.   One subsystem includes apparatus for receiving commands requiring a priority interrupt by storing vectors in a random access memory.  These vectors which are addressed by the channel number of the interrupting subsystem indicate the offset to be added to the base address of an exception vector table.  The exception vector stores the starting address in a memory of the requested interrupt routine.

Abstract: ACTION FOR UPRIGHT PIANO            Abstract of the Disclosure The subject action is a modification of the tradi-tional upright action.  The traditional jack spring is elim-inated.  Its function is assumed by a jack/repetition spring, which is a compression spring adjustably mounted between the jack near the end that engages the hammer butt and a pilot attached to a threaded shaft through the back stop portion of the hammer  assembly.   The hammer  return spring mounting enables adjustment of the range of force applied by the spring to the hammer.  The force range magnitude is such that the hammer return torque is commensurate to the torque that would be applied by gravity if the hammer shank were mounted horizontally instead of vertically.  The operating force of the jack/repetition spring is related to that of the hammer return spring in such a way that re-engagement of the jack with the hammer butt is assured before hammer return beyond the back-checked point.   The ends of the jack/repetition spring are geometrically located to allow the elements of the action to keep in intimate contact after re-engagement, mak-ing possible the elimination of the bridle tape and wire, and to provide a function that feels smooth and tight, not loose. The  interaction  between  the  springs  as  applied produces enough return force on the key to allow use of weights in the played end of the key to provide the desirable  inertial resistance of a grand action to the player's touch on the keys.  With the subject action properly adjusted, the hammer assembly rests upon the jack, rather than the traditional rest rail and therefore there is space between the hammer shank and hammer rest rail when the action is at rest.

Title: Anti-bounce logic for critical loads
Inventor: KIDDER KENNETH B
IPC: F23N1/04
Filed: 1989-05-05
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE        An anti-bounce system for control of critical loads is provided.  A control system contains two subsystems.  The first subsystem functions for normal control of the critical loads, but has a relatively long information processing time.  This long time might prevent the system from controlling the loads in a safe manner.  The system has a second subsystem that has a very rapid processing time.  Both of the subsystems are connected to the load by coupling means to monitor as a feedback signal the exact state of the loads.  The second subsystem overrides the first, and disconnects power whenever there has been an interruption of power for a short period of time.
