Title: **Toshiyuki Iwasawa: Pioneer in Ink Jet Technology**
Introduction
Toshiyuki Iwasawa is a noteworthy inventor based in Tokyo, Japan, known for his significant contributions to the field of ink jet technology. With a portfolio of five patents, his innovative designs have considerably advanced the functionality and performance of ink jet recording apparatuses.
Latest Patents
Toshiyuki Iwasawa's latest patents include groundbreaking inventions that enhance the efficiency and precision of ink jet systems. One of his notable patents is the **Ink Jet Recording Apparatus**, which features an ink nozzle plate with ink discharge channels that work in conjunction with an air nozzle plate. This innovative design incorporates air discharge channels aimed at the ink discharge channels to facilitate the jetting of ink. The inclusion of a power source that generates an electric field through the ink allows for an extended ink meniscus, resulting in improved jetting performance. Furthermore, the apparatus uses a heating mechanism to raise the temperature of the air nozzle plate, which vaporizes any water adsorbed in the air discharge channels, thereby stabilizing the ink jet volume.
Another remarkable patent is the **Ink Jet Recording Apparatus with Density Control Function**. This multi-nozzle apparatus is ingeniously arranged to eject ink toward a writing surface activated by an electric field generated from ink ejecting signals. An integrated circuit produces a density information signal that reflects the recording density for each ink nozzle. The system's control unit, responsive to this signal, stores density-to-signal characteristics in multiple memories to optimize the ink ejecting amount for each nozzle based on the recording density requirements.
