Latest Patents

Ishikawa's latest patents include a "Charging apparatus for an electronic device" and a "Magnetic read/write apparatus." The charging apparatus is designed to charge a power storage device within an electronic device. It utilizes a power source that provides direct current, which is alternated in direction through a pair of primary coils. This setup induces alternating current in a secondary coil of the electronic device. The design ensures that during charging, the electronic device is mounted to the casing's outside surface, allowing for optimal magnetic flux flow through the secondary coil and coil yoke. The oscillating signal frequency is preset to maximize induced current without disrupting the analog mechanisms within the device.

The magnetic read/write apparatus features a media hub made of magnetic material, equipped with a magnetic disk. The positioning of the media hub in both axial and radial directions is achieved through a spindle hub and a center core. This innovative design allows for a compact spindle hub while ensuring excellent head contact.
