Toshimi Tajima is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of paper manufacturing through his innovative patents. With a total of 2 patents, Tajima's work focuses on enhancing the efficiency and quality of paper production processes.
Latest Patents
Tajima's latest patents include a "Stock liquor pressure pulsation absorbing apparatus and method" and an "End portion flow rate regulating apparatus for a paper machine headbox." The stock liquor pressure pulsation absorbing apparatus is designed to absorb pressure pulsations in a frequency range of 0.01 to 100 Hz. This apparatus utilizes a by-pass pipe to extract a portion of stock liquor from a master pipe, which is then supplied to a paper machine headbox. A control pump returns the extracted stock liquor into the by-pass pipe, while a detector monitors the stock liquor pulsation pressure to ensure accurate control. This innovation helps minimize variations in basis weight and ensures a stable supply of high-quality final products.
The end portion flow rate regulating apparatus is compact and effectively regulates the flow directions of jets of wet paper stock during operation. It prevents stagnation by utilizing tubes with varying inner diameters, allowing for the adjustment of flow rates through flow rate regulating valves. This flexibility enables the production of paper webs with diverse properties.
