Title: Hironobu Amemiya: Innovator in Optical Disc Technology
Introduction
Hironobu Amemiya is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of optical disc technology, holding a total of 5 patents. His innovative work has been instrumental in advancing the functionality and efficiency of optical disc apparatuses.
Latest Patents
Amemiya's latest patents include an "Adjusting method for an optical disc apparatus." This invention involves a relative adjustment between an optical disc rotating mechanism and an optical pickup. The adjustment is achieved by rotating a rotary member against a biasing force of an engaging projection. As the rotary member rotates, the projection slides on an inclined surface, altering the relative position between the rotary member and a bottom wall of a subsidiary chassis. This adjustment results in a varied inclination of the subsidiary chassis relative to the main chassis, with the adjusted condition maintained by an engaging force between an engaging groove and the engaging projection.
Another significant patent is the "Drive device including a restart drive detection element." This drive device features a feed mechanism that moves a control object to control its positioning. It includes a motor that serves as the drive source and a control means that manages the motor's operation. The control means has an operation history memory unit that stores whether the motor is performing an initial start or a restart. This innovation helps avoid thermal shutdown due to overheating of the driver IC during intermittent operation, ensuring that the actual feed amount aligns with the control commands.
