Abstract: A flavor inhaler cartridge includes a housing, a movable lid member, an aerosol flow passage, a turning member, and a motion conversion mechanism. The housing includes a reservoir space to house a liquid and an atomizing space to atomize the liquid. With the movable lid member, the reservoir space and the atomizing space are openably/closably partitioned. The aerosol flow passage supplies an aerosol generated by the atomization of the liquid from the atomizing space to outside of the housing. The motion conversion mechanism converts the circumferential turning motion of the turning member into an axial linear motion of the lid member. The lid member is fixed to the motion conversion mechanism. The motion conversion mechanism is configured such that circumferentially turning the turning member moves the lid member in a direction of approaching the turning member and communicates between the reservoir space and the atomizing space.

Abstract: A nitride semiconductor device is disclosed. The semiconductor device is formed by a process that first deposits a silicon nitride (SiN) film on a semiconductor layer by the lower pressure chemical vapor deposition (LPCVD) technique at a temperature, then, forming an opening in the SiN film for an ohmic electrode. Preparing a photoresist on the SiN film, where the photoresist provides an opening that fully covers the opening in the SiN film, the process exposes a peripheral area around the opening of the SiN film to chlorine (Cl) plasma that may etch the semiconductor layer to form a recess therein. Metals for the ohmic electrode are filled within the recess in the semiconductor layer and the peripheral area of the SiN film. Finally, the metals are alloyed at a temperature lower than the deposition temperature of the SiN film.
