Title: Hisaji Kawai: Innovator in Image Forming Technology
Introduction
Hisaji Kawai is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of image forming technology, holding a total of 7 patents. His work focuses on enhancing the efficiency and reliability of electronic devices.
Latest Patents
One of Hisaji Kawai's latest patents is an image forming apparatus that detects the status of a transport belt that transports recording media. This innovative apparatus includes an image forming device, a transport belt, an optical sensor, an ultrasonic sensor, and a controller. The transport belt is responsible for moving the recording sheet, while the optical sensor emits light to the transport belt and receives the reflected light. The ultrasonic sensor transmits ultrasonic waves to the transport belt and receives the waves transmitted through it. The controller determines whether the outputs from the optical and ultrasonic sensors indicate normal or abnormal values, executing predetermined control based on the combination of these results.
Another notable patent is an electronic apparatus that predicts the remaining service life of a limited-life component based on frequency analysis of sound data. This apparatus consists of a drive unit with a drive roller, a driving motor, and a limited-life component. It also includes a sound collecting device that gathers sound from the limited-life component and outputs sound data. The storage device holds sound pressure levels corresponding to specific frequencies of the limited-life component for different lengths of remaining service life. The controller analyzes the frequency of the sound data at predetermined time points, compares the acquired sound pressure level with the stored levels, predicts the remaining service life, and displays this information on a display device.
