Latest Patents

Monzen's latest patents include a charging device that features two distinct charging modes. This innovative device is designed to include multiple battery pack connection parts, allowing for appropriate charging while switching between different battery packs. The microcomputer within the device can execute either a first mode or a second mode, depending on the connection of the battery packs. In the first mode, the charging target battery packs are switched before they are fully charged, enabling sequential charging. Conversely, in the second mode, the battery packs are fully charged before switching occurs. The device also detects the type or state of the charging target battery pack during each switching process.

Another significant invention by Monzen is a reciprocating tool that aims to reduce vibrations during operations, thereby improving work performance and processing precision. This tool comprises a transmission gear part and a counterweight part. The transmission gear part includes a bevel gear that rotates in one direction while a weight rotates in the opposite direction, both driven by a motor. The design ensures that the
