Publication number: 20240051816Abstract: A microelectromechanical element is provided that includes a first device part and a second device part, and a motion-limiting structure having a first stopper bump and a second stopper bump. The first and second stopper bumps extend from the first device part toward the second device part. When one of the device parts moves toward the other device part in the out-of-plane direction and crosses a displacement threshold, the first stopper bump comes into contact with the second device part before the second stopper bump contacts the second device part, and the second stopper bump comes into contact with the second device part before the first device part contacts with the second device part.Type: ApplicationFiled: August 11, 2023Publication date: February 15, 2024Inventors: Pekka LEHTINEN, Akira Konno, Matti Liukku

Patent number: 11796561Abstract: The present invention relates to capacitive micromechanical accelerometers, and in particular to acceleration sensors with movable rotors which may rotate out of a substrate plane when the accelerometer undergoes movement with an acceleration component perpendicular to the substrate plane. The capacitive micromechanical accelerometer includes additional damping springs to reduce unwanted movement of the rotor in the substrate plane, thereby reducing the parasitic capacitance that results from motion of the rotor in the substrate plane. The damping springs are vertically recessed with respect to other components of the accelerometer in order to minimise the effect of the damping springs on movement of the rotor out of the substrate plane.Type: GrantFiled: August 3, 2022Date of Patent: October 24, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Akira Konno, Yoshitaka Kato, Ville-Pekka Rytkonen

Publication number: 20220306453Abstract: The present invention relates micro-electromechanical systems (MEMS); in particular to a comb channel structure for decreasing damping asymmetry of comb electrodes used to measure movement of components with MEMS devices. The channel is formed by a series of recesses formed in the comb fingers of the comb electrodes, or in the cap or handle wafer adjacent to the comb fingers. The channel increases the cross sectional area of the path through which gas can move into or out of the space between the comb electrodes as the comb electrodes move with respect to one another. Thus, when there is a damping asymmetry caused by a difference in the distance between the comb electrode and the cap wafer, and the comb electrode and handle wafer, the channel is employed on the side of the comb electrode with the smaller distance to the adjacent wafer to reduce the damping asymmetry.Type: ApplicationFiled: March 14, 2022Publication date: September 29, 2022Inventor: Akira KONNO

Patent number: 8926678Abstract: Provided is a handpiece of a laser treatment device which can restrict a temperature rise of body tissues in a path from an irradiation portion to a target region more effectively than in the related art. The handpiece 10 includes an optical fiber 16 which guides laser light emitted from a pulse light source, and a revolving holder which holds a tip portion 64 of the optical fiber 16 such that the tip portion 64 is tilted with respect to a rotational axis C0 to direct an optical axis C1 of the laser light towards a target point P located on the rotational axis C0 and revolves the tip portion 64 of the optical fiber 16 about the rotational axis C0. Further, a pulse number of the pulse light source per unit time and a number of revolutions of the tip portion 64 of the optical fiber 16 per unit time are determined such that the pulse number of the pulse light source per unit time is not an integral multiple of the number of rotations of the tip portion 64 of the optical fiber 16 per unit time.Type: GrantFiled: April 2, 2012Date of Patent: January 6, 2015Assignee: Altech CorporationInventor: Akira Konno
