Introduction

Toshio Otsuka is an inventor associated with Tokyo, Japan, and Sapporo Breweries Limited. His patent work includes an apparatus designed to protect a filter’s pre-coat layer during the transition to filtration.

Latest Patents

Otsuka is credited with 1 patent: “Filtration Apparatus with Means for Preventing Peeling Off of a Pre-Coat.” The invention concerns an apparatus with upright tubular filter elements coated with a filter-aid pre-coat layer. It provides a gas exhaust tube or liquid drain tube connected to the upper or lower part of a filter element. This arrangement allows the pre-coat-forming liquid to be discharged before the liquid to be filtered is introduced, helping prevent the two liquids from mixing and reducing the risk of defects in the pre-coat layer.

Career Highlights

Otsuka’s documented patent contribution focuses on improving the changeover from pre-coat formation to filtration. The design addresses liquid removal and pre-coat integrity within the filtration apparatus.

Collaborations

Otsuka’s listed coworkers include Hiroshi Kuroda and Hirohisa Sahara. The available information identifies these colleagues but does not specify their roles in the patent.

Conclusion

Toshio Otsuka’s patent describes a practical filtration improvement that helps preserve the pre-coat layer and avoid mixing liquids during the transition to filtering.
