Summary of the patent applications from Murata Manufacturing Co., Ltd. on November 30th, 2023

Murata Manufacturing Co., Ltd. has recently filed several patents related to various technologies. These patents cover a range of inventions, including cases with sliding shutters for discharge ports, acoustic wave filters and devices, power amplification circuits, ultrasonic motors, antenna devices, and methods of manufacturing secondary batteries.

In terms of the cases with sliding shutters, the patents describe a case that includes a guide portion to facilitate the sliding movement of the shutter. The shutter can be selectively inserted into different branching pathways depending on whether a pin is fitted into the case or not. This allows for easy identification of the shutter's position from the exterior.

The patents related to acoustic wave filters and devices describe circuits and structures that improve the performance of these devices. For example, one patent describes a filter circuit connected to input-and-output terminals and a canceling circuit connected in parallel to a portion of the first path. The canceling circuit includes acoustic wave resonators connected to the ground, with at least one resonator having an anti-resonant frequency within the pass band of the filter circuit.

The power amplification circuit patent describes a circuit that adjusts the amplification based on the input signal. It includes a splitter with variable inductance and capacitance elements, a carrier amplifier, a peaking amplifier, and a combiner.

The ultrasonic motor patent describes a motor consisting of a stator and a stator fixing member. The stator has a vibrating body with a through-hole and a piezoelectric element, while the stator fixing member includes a rotor and a whirl-stop portion that fits into the through-hole.

The antenna device patent describes a device with ground and radiating electrode plates, feeder lines, and a ground line. The radiating electrode plates are positioned facing the ground electrode plate, with the second radiating electrode plate located between the ground electrode plate and the first radiating electrode plates. The ground line connects the second radiating electrode plate to the ground electrode plate.

Finally, the method of manufacturing a secondary battery patent describes a simplified process using laser welding to join the cup-shaped and lid-shaped exterior members of the battery.

Notable applications:

  • Cases with sliding shutters for discharge ports
  • Acoustic wave filters and devices
  • Power amplification circuits
  • Ultrasonic motors
  • Antenna devices
  • Methods of manufacturing secondary batteries.
