Title: Ryouhei Shimizu: Innovator in Memory Apparatus and Circuit Pattern Formation
Introduction
Ryouhei Shimizu is a notable inventor based in Koshigaya, Japan. He has made significant contributions to the fields of memory apparatus and circuit pattern formation. With a total of 5 patents to his name, Shimizu's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Shimizu's latest patents is a memory apparatus using tunnel current techniques. This invention features a scanning tunneling microscope memory apparatus that comprises first and second integrated circuit (IC) substrates. The apparatus includes first and second cantilevers, which can be moved by piezoelectric elements, arranged on the respective IC substrates. Tunnel current probes are positioned on the free end of the first cantilever, while a recording element is located on the free end of the second cantilever. The cantilevers are designed to be spaced apart yet overlap, allowing the tunnel current probes to face the recording element. Additionally, one of the substrates incorporates a charge coupled device (CCD) circuit, a control circuit for managing the CCD circuit and cantilevers, and a drive circuit that includes a preamplifier, a write circuit, and a servo circuit.
Another significant patent is a circuit pattern forming apparatus using MU-STM. This apparatus is designed to create a predetermined circuit pattern on a circuit substrate utilizing a .mu.-STM write head. The write head consists of a substrate with a flat surface and multiple micro chip electrodes that are formed upright on the surface. Each chip electrode's distal end is set to a constant level, and the apparatus includes scanning means for moving the micro chip electrodes and the circuit substrate relative to each other in two-dimensional directions.
