Title: Toru Nakazawa: Innovator in Coating Technology and Electrophotosensitive Materials
Introduction
Toru Nakazawa is a prominent inventor based in Osaka, Japan. He has made significant contributions to the fields of coating technology and electrophotosensitive materials. With a total of 18 patents to his name, Nakazawa continues to push the boundaries of innovation in his industry.
Latest Patents
One of Nakazawa's latest inventions is a drum chucking device. This device is designed to keep a drum vertical while it is immersed in a coating liquid. The chucking device features upper and lower pressure members with tapered peripheral surfaces. An annular elastic member is fitted between these surfaces, allowing for a secure grip on the drum. When the drum is chucked, compressed air is used to move the lower pressure member away from the upper member, enabling the elastic member to be inserted into the drum. Once the air is released, the pressure members contact each other, causing the elastic member to press outward and tightly contact the inner surface of the drum. This innovative design ensures that the drum is securely held in place during the coating process.
Another notable patent involves an electrophotosensitive material that includes a conductive substrate and a photosensitive layer. This layer comprises a perylene compound and an X-type metal-free phthalocyanine as a charge-generating ingredient, along with a diamine derivative as a charge-transferring ingredient. This invention is particularly remarkable for its superior sensitivity and reproducibility, making it a valuable advancement in the field.
