Title: Junichi Ohno: Innovator in Variable Capacity Compressors

Introduction

Junichi Ohno is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of variable capacity compressors, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is for a "Wobble plate type variable capacity compressor with a capacity detector." This invention features a non-rotatory wobble plate supported on a magnetic material support member, allowing it to wobble non-rotatively to move compressing pistons within cylinder bores. The design includes a steel drive shaft driven by a source via a solenoid-operated clutch, which causes the wobble plate to change its angle of inclination, thereby varying the compressor's capacity. Additionally, a capacity detecting unit is integrated, which utilizes a permanent magnet and a magnetic sensor to generate electric signals that determine the compressor's capacity. This innovative design also prevents erroneous signals through a unique arrangement of magnetic flux.

Another significant patent is for a "Control circuit unit for a variable capacity compressor." This control circuit is designed to manage the energization of a solenoid in a variable capacity compressor, typically used in car air-conditioning systems. It includes a switching unit that establishes electric conduction for the solenoid and a voltage control circuit that applies a high starting voltage initially, followed by a lower retaining voltage for continued operation.
