Single-longitudinal mode laser with orthogonal-polarization traveling-wave mode

Номер: US0007742509B2
Принадлежит: Photop Technologies, PHOTOP TECHNOLOGIES

A single longitudinal-mode laser includes a first mirror and a second mirror that define a laser cavity therein that does not include a linear polarizer. A birefringent gain medium can generate a lasing light at a lasing wavelength along a light propagation direction in response to a pump light at a pumping wavelength. The birefringent gain medium has an optical axis substantially perpendicular to the light propagation direction. A first wave plate positioned between the first mirror and the birefringent gain medium is a quarter wave plate at the lasing wavelength and a whole wave plate at the pumping wavelength. A second wave plate is positioned between the birefringent gain medium and the second mirror. The first wave plat and the second wave plate in part produce a single longitudinal mode in the lasing light.

Принадлежит: Nippon Suisan Kaisha Ltd

Provided is a contact sensor device for fish, said contact sensor device being capable of adjusting the elastic force of an elastic member in accordance with variations in the magnitude of the tensile force on a mark during feeding which varies depending on the growth state of relatively large fish, and said elastic member preventing overloading of a pressure sensor and breakage of a fishing line. The present invention includes: a fishing line 22, an end part of which is attached to a mark 24 to be pulled by a fish; a pressure sensor 18 that senses pressure; a pressing piece 28 that is connected to the other end part of the fishing line 22, and transmits the tensile force acting upon the fishing line 22 to an operation part 26 of the pressure sensor 18; and an elastic member 32 that prevents overloading of the pressure sensor 18 by the pressing piece 28 and breakage of the fishing line 22. The elastic member 32 is provided with an elastic force adjustment means 38 that adjusts the elastic force of the elastic member 32 in accordance with the tensile force acting upon the pressing piece 28.

Pulp molded cup lid and manufacturing method therefor

Номер: US20240294307A1
Принадлежит: Shurcon Manufacturing Zhejiang Co ltd

A pulp molded cup lid includes a lid top portion, a transverse extension portion and a longitudinal extension portion. The transverse extension portion is connected to a lower side of an outer edge of the lid top portion and extends radially outward. The longitudinal extension portion is connected to an outer edge of the transverse extension portion and extends axially downward. The longitudinal extension portion is cylindrical. The pulp molded cup lid further includes an inner convex buckle disposed on an inner wall of the longitudinal extension portion. The inner convex buckle is integrally formed with the longitudinal extension portion. The inner convex buckle protrudes inward relative to the inner wall of the longitudinal extension portion. An outer wall of the longitudinal extension portion defines a rolling groove. The rolling groove is configured to further reduce an inner diameter of the inner convex buckle.

A pulp molded cup lid, comprising a lid top (10), a transverse extension portion (20) connected to the lower side of an outer flange of the lid top (10) and extending outward in the radial direction, and a longitudinal extension portion (30) connected to the outer edge of the transverse extension portion (20) and extending downward in the axial direction, the longitudinal extension portion (30) being cylindrical. An inner convex buckle (40) protruding inward is integrally formed on the inner wall of the longitudinal extension portion (30), and a rolling groove (50) enabling the inner diameter of the inner convex buckle (40) to be further reduced is formed in the outer wall of the longitudinal extension portion (30). The cup lid has the advantages that: the shrinkage of the inner convex buckle can improve the locking force of buckling the cup lid on a cup and the sealing performance that the cup lid is removed and covered on the cup many times, and the technical problems of unreasonable design and the like in the prior art are solved.

Micro speaker and diaphragm mold

Номер: US12089023B2
Принадлежит: AAC Microtech Changzhou Co Ltd

The present invention discloses a micro speaker, including a frame with a containment space, a magnetic circuit system and a vibration system accommodated in the containment space. The vibration system includes a first diaphragm, a dome skeleton fixed to the first diaphragm, and a voice coil fixed on the dome skeleton. A welding plate structure is fixed on the dome skeleton, and a first circuit board and a second circuit board fixed to the frame respectively. The first diaphragm includes a first diaphragm area and a second diaphragm area. The thickness of the first diaphragm area is greater than the thickness of the second diaphragm area. The local thickening material is adopted to avoid the problem of speaker rigidity asymmetry caused by unbalanced heat distribution, so as to realize the stable operation of the speaker, and the manufacturing process is simple.
