Latest Patents

Mashima's latest patents include a folding portable wireless apparatus. The objective of this invention is to provide a folding-type portable wireless equipment that achieves excellent antenna characteristics in both opened and closed states. This is accomplished with a simple configuration that does not compromise miniaturization. The design features a first case and a second case, with a first circuit board in the first case and a second circuit board in the second case. A bendable coupling portion mechanically connects the two cases, while a flexible coupling element electrically links the circuit boards. The invention also includes a radio circuit portion and an antenna element that connects to the radio circuit via a feeder line. A switching portion selectively connects and disconnects the first circuit board and the antenna element based on the opened or closed state of the device.

Another notable patent is for a folding mobile radio device. This device addresses the issue of gain reduction when in a closed state. It includes a first case, a second case, and a jointing portion that allows the two cases to open and close. The conductor element is arranged in the first case, while the feeding element is in the second case. In the open state, the conductor and feeding elements are magnetically coupled, enhancing performance, whereas in the closed state, they are apart and not coupled.
