Title: Masami Takemasa: Innovator in Motor Technology and Air Conditioning Systems
Introduction
Masami Takemasa is a notable inventor based in Konan, Japan. He has made significant contributions to the fields of motor technology and vehicle air conditioning systems. With a total of three patents to his name, Takemasa's innovations reflect a commitment to enhancing efficiency and functionality in engineering.
Latest Patents
One of Takemasa's latest patents is a brushless motor featuring a lubrication system for upper and lower bearings. This invention presents a simple structure that facilitates the mounting of bearings while maintaining lubricating oil at an adequate level. It also ensures an optimal distance between the rotor and the case housing to prevent freezing, reduce capacity, and minimize noise. The design includes bearing stoppers that secure the upper end edge of each bearing, along with a felt that contacts the lower portion of each bearing stopper. The invention sets specific limits on the distance between the rotor and the case housing to prevent water connection due to capillary action and surface tension.
Another significant patent is for air-conditioning equipment designed for vehicles. This system includes first and second local shutter control units, each equipped with a motor for moving a shutter. The controlling device responds to heat load signals to manage the drive circuit, allowing independent control of each shutter. This innovation prevents all air-conditioning functions from halting simultaneously, a common issue in conventional systems with a central control unit.
