Title: Masayoshi Abe: Innovator in Circuit Design and Rubber Molding Technology
Introduction
Masayoshi Abe is a prominent inventor based in Osaka, Japan. He holds a total of 7 patents that showcase his contributions to technology, particularly in the fields of circuit design and rubber molding apparatus.
Latest Patents
Abe's latest patents include a dropout detection circuit and an optical disc apparatus. The dropout detection circuit features a high-speed envelope detection circuit that detects the envelope of a reflection signal of a light beam with a first time constant. It also includes a low-speed envelope detection circuit that detects the envelope with a second time constant larger than the first. A differential circuit generates a difference signal indicating the difference between the envelopes detected by the envelope detection circuits. Additionally, a comparator converts the difference signal to a binary value according to a predetermined binary criterion. This innovative design allows for stable dropout detection during both recording and reproduction.
Another significant patent is a control system for a continuous rubber molding apparatus. This system comprises a feed portion for feeding rubber material, an extruder for kneading the material, and a gear pump for delivering the rubber to a forming nozzle. The control system includes a pressure sensor for sensing pressure in the gear pump, a pressure comparator for comparing sensed pressure with a set value, and a motor controller for adjusting the motor's revolutions based on the comparison results. This invention is crucial for the efficient production of rubber ribbons used in tire manufacturing.
