The modulator-integrated semiconductor laser (100) comprises a semiconductor laser (101), and an electro-absorption modulator (102) and an optical attenuator (103) which are monolithically integrated in series at a subsequent stage of the semiconductor laser (101). The control unit (44) performs control in such a manner that the DC bias voltage applied to the optical attenuator (103) becomes larger as the temperature of the modulator-integrated semiconductor laser (100) rises.

Provided are: a structure having a foamed resin layer, which is capable of forming the foamed resin layer in a short time; an interior body; and a method for manufacturing an electronic device. A base material (5) coated with a mixture (10) is accommodated in a cavity (4) of a mold (1). The mixture (10) contains an ultraviolet-curable adhesive and thermally expandable microcapsules. When the mold (1) is closed and the mixture (10) is irradiated with ultraviolet light, the adhesive resin component contained in the adhesive is polymerized, and the microcapsules are heated by heat generated in the polymerization reaction. A foamed resin layer (11) adhered to the substrate (5) is manufactured by expanding the heated microcapsules.

The invention discloses a hard wear-resistant metal ceramic coating material and a preparation method thereof, and the preparation method is characterized by comprising the following steps: preparing multi-component composite metal ceramic powder based on the preparation of NiCoCr medium-entropy alloy powder doped with Ti-O elements, preparing a thermal spraying coating by adopting HVAF, then carrying out laser shock treatment, and controlling a chemical short-range ordered nanophase to separate out a reinforced binding phase, so as to obtain the hard wear-resistant metal ceramic coating material. And finally, the metal ceramic hard wear-resistant coating with the NiCoCr-Ti-O medium entropy alloy of the FCC structure as the binding phase is obtained. The invention overcomes the problem of poor wear resistance of the metal ceramic coating manufactured in the prior art, and can be used for coating treatment of various key parts serving in the fields of petrochemical industry, coal chemical industry, polycrystalline silicon, new energy and the like in the advanced manufacturing fields of steam turbines, gas turbines and the like.

This invention discloses a vibration-type respiratory sputum clearance device, relating to the field of medical device technology. It includes a vest body. Multiple independent liquid-coupled vibration units are arranged on the inner side of the vest, corresponding to the upper and lower lobes of both lungs and the projected lung region on the back. Each liquid-coupled vibration unit includes a sealed liquid-sealed bag, and a vibration unit is disposed on the outer side of each sealed liquid-sealed bag. The sealed liquid-sealed bag is integrally embedded and fixed in a flexible interlayer on the inner side of the vest. The interior of the sealed liquid-sealed bag is filled with a vibration-transmitting liquid. The vibration-transmitting liquid filled in the sealed liquid-sealed bag of this invention, relying on its incompressible and highly fluid physical properties, can efficiently transmit and convert the high-frequency micro-vibrations generated by the double-layer piezoelectric sheet, forming a dual mechanical action of shallow loosening and deep oscillation, perfectly adapting to the sputum clearance needs of the soft tissues of the chest and back and the deep airways of the thoracic cavity.
