Title: Takeo Hohda and Camera Power-Supply Control

Introduction

Takeo Hohda is an inventor associated with Sakai, Japan, and Minolta Camera Kabushiki Kaisha. His work includes an invention addressing power management in cameras equipped with electronic flash and data-recording functions.

Latest Patents

The available information lists 1 patent for Hohda: “Power Supply Control Device for Cameras.” The invention concerns a camera that uses a shared power source for its exposure-control circuit and two flash devices: one to illuminate the scene and another to illuminate data being recorded.

To prevent the scene flash’s capacitor-charging process from causing a voltage drop that could affect exposure control, the design allows the main capacitor’s charging circuit to be switched on manually, independently of the camera’s exposure operation. A separate capacitor for the data-illumination flash is charged in conjunction with the camera release, before exposure begins.

Career Highlights

Hohda’s listed patent reflects an engineering focus on coordinating camera power use and flash operation. Its design aims to support reliable exposure control while enabling both scene illumination and the recording of illuminated data.

Collaborations

Hohda is associated with Minolta Camera Kabushiki Kaisha. Yoshiharu Ohta and Shinji Tominaga are identified as his coworkers.

Conclusion

Takeo Hohda’s camera power-supply invention addresses the practical challenge of managing shared power among exposure-control and flash systems, contributing to the coordinated operation of camera functions.
