  • Publication number: 20250025642
    Abstract: A compressor includes a shading motor as a power source, and is provided with a discharge port that discharges compressed air generated by driving the shading motor. The shading motor includes a stator that is made of a soft magnetic material and has an apparent volume of 78000 mm3 or less. A load reduction mechanism reduces a load applied to the shading motor by suppressing a pressure increase in the flow path over a period from a first time point at which the shading motor starts driving to a second time point at which the rotation speed of a rotor reaches a predetermined rotation speed.

  • Patent number: 10434266
    Abstract: A nebulizer kit includes an atomizer generating an aerosol, and a particle sorting route communicating with the atomizer and sorting liquid particles in the aerosol to adjust a particle diameter distribution thereof, and guiding the aerosol to a discharge port. The particle sorting route includes a first particle sorting route with a uniform cross-sectional area in the first direction and a second particle sorting route with an inner end wall that curves from the first direction toward a second direction included in the same plane as the first direction. The first particle sorting route guides the aerosol to the second particle sorting route in the first direction, and the inner end wall of the second particle sorting route guides the aerosol in the second direction while aerosol particles with a certain particle diameter or more are attached thereto.

  • Patent number: 6498094
    Abstract: An underlying conductive film made of iridium and having a thickness of about 0.1 &mgr;m is formed in a contact hole formed in an insulating film covering a transistor formed in a substrate, except in the top portion of the contact hole. The underlying conductive film covers the sidewall portions of the contact hole and the top surface of the drain region but does not completely fill in the contact hole. A plug made of platinum is filled in the contact hole up to the top portion thereof. Over the contact hole of the insulating film, there is formed a capacitor composed of a lower electrode made of platinum, a capacitor insulating film made of SrBi2Ta2O9, and an upper electrode made of platinum in contact relation with the respective upper ends of the underlying conductive film and the plug.

  • Patent number: 6323053
    Abstract: As a pretreatment of a substrate, a substrate of Si having the (111) surface orientation as a main surface is soaked in hydrofluoric acid, so as to form a H atomic layer for terminating dangling bonds on the main surface of the substrate. Then, the substrate is placed in a highly evacuated growth chamber in an MBE system, and a Ga molecular beam and a Se molecular beam are supplied onto the H atomic layer on the substrate, so as to grow a buffer layer of GaSe, that is, a van der Waals crystal. Next, with the supply of the Se molecular beam stopped, a N2 gas activated by using radio frequency or electron cyclotron resonance is supplied instead as a nitrogen source onto the buffer layer on the substrate, so as to form a semiconductor layer of GaN.

  • Patent number: 5917171
    Abstract: The present invention relates to a bar code reading apparatus that is useful for recognizing by human eyes whether a light beam is being projected onto a bar code symbol. The bar code reading apparatus contains a first and second light source to radiate a first ray and a second visible ray, respectively. The second visible ray has higher visibility than first light beam for human eyes. As a result, an operator can easily recognize whether the light beams are projected onto a bar code symbol. Another bar code reading apparatus contains first and second photo detectors for receiving a first and a second reflected beam, respectively. With this arrangement two different bar code symbols can be simultaneously read by the bar code reading apparatus.

  • Patent number: 5323262
    Abstract: A wavelength conversion device exhibiting an excellent wavelength conversion efficiency is provided by forming it in such a manner that an LiTaO.sub.3 substrate is subjected to a proton exchange treatment to form a proton-exchange layer before the proton-exchange layer is subjected to heat treatment to form a domain-inverted structure. Heat treatment is performed at a high temperature rising speed to prevent the thermal diffusion of the proton-exchange layer so that the expansion of the domain-inverted structure to be formed in the proton-exchange layer is restrained. As a result, a higher harmonic wave wavelength conversion device can be provided.
