Latest Patents

The provided patent information describes an apparatus and method for producing an alignment layer for a liquid crystal display. The process heats substrates on trays in a first load-lock chamber, then uses vacuum deposition to apply evaporated silicon oxide particles to at least one substrate. The deposition takes place at an angle of 45 to 60 degrees from the substrate’s surface normal as the trays move through the deposition chamber. The substrates are then cooled in a second load-lock chamber.

The described process also specifies conditions for controlling deposition uniformity based on the positions of the substrate and evaporation source. It notes that the alignment layer may be deposited at an angle between 3 and 10 degrees. The supplied data repeats this patent description, so it is presented here as one distinct invention rather than as two separate patent summaries.

Career Highlights

Nakanishi’s listed work focuses on manufacturing technology for liquid crystal display components. The described approach combines staged heating and cooling with angled vacuum deposition, offering a controlled process for forming alignment layers on display substrates. His associated company is Victor Company of Japan, Limited.

Collaborations

The supplied information names Takeshi Hosoya and Masami Sonda as Nakanishi’s coworkers. It does not specify their roles in the patent or describe particular joint contributions.

Conclusion

Tatsushi Nakanishi’s listed patent work addresses the production of silicon-oxide alignment layers for liquid crystal displays through a carefully controlled deposition process.
