Abstract: A refrigeration cycle device includes a compressor, an upstream branch portion, a heating portion, a decompression portion, a bypass passage, a bypass flow adjustment portion, and a mixing portion. The mixing portion mixes a bypass side refrigerant flowing out from the bypass flow adjustment portion with a decompression-portion side refrigerant flowing out from the decompression portion, and causes the mixed refrigerant to flow to a suction port side of the compressor. The mixing portion mixes the bypass side refrigerant and the decompression-portion side refrigerant such that an enthalpy difference obtained by subtracting an enthalpy of an ideal homogeneously mixed refrigerant from an enthalpy of a suction side refrigerant actually sucked into the compressor is equal to or less than a predetermined reference value.

Abstract: A solid-state imaging apparatus that performs color imaging using visible light and imaging using infrared light, the solid-state imaging apparatus including a plurality of two-dimensionally arranged pixel cells, in each of which a filter mainly transmits one of visible light and infrared light, wherein filters are arranged such that a first unit of arrangement where a plurality of filters that mainly transmit visible light are arranged and a second unit of arrangement where a filter that mainly transmits visible light and a filter that mainly transmits infrared light are arranged are alternately arranged in both a row direction and a column direction. Also, in the first unit of arrangement are arranged filters including three kinds of filters each transmitting one of red light, green light and blue light and in the second unit of arrangement are arranged four kinds of filters each transmitting one of red light, green light, blue light and infrared light.

Abstract: A vehicle-mounted imaging device that is mounted in an automobile and performs color imaging has been provided with a plurality of two-dimensionally arranged pixel cells. In each of the pixels, a color filter separates incident light by a multilayer interference filter. The multilayer interference filter is composed of two ?/4 multilayer films and a spacer layer sandwiched therebetween. The multilayer interference filter transmits light in a wavelength region that corresponds to an optical thickness of the spacer layer. The ?/4 multilayer films and spacer layer are composed of inorganic materials.

Abstract: A solid-state imaging device includes a color filter that selectively transmits incoming light. The color filter includes two ?/4 multilayer films, and an insulation layer sandwiched between the two ?/4 multilayer films. Here, each of the ?/4 multilayer films is constituted by a plurality of dielectric layers, and the optical thickness of the insulation layer is not ?/4. Since this color filter has a smaller thickness, the solid-state imaging device has a smaller size.

Abstract: A wavelength separation filter 206 is composed of ?/4 multilayer films 302 to 304 that are sequentially laminated on a multilayer interference filter 301. The multilayer interference filter 301 is composed of two ?/4 multilayer films with a dielectric layer sandwiched therebetween. Also, the multilayer interference filter 301 is composed of parts 301B, 301G, 301R that transmit blue light, green light, and red light, respectively. The multilayer interference filter 301 wavelength-separates visible light. The ?/4 multilayer films 302 to 304 reflect light having a wavelength within wavelength ranges having set-wavelengths of 800 nm, 900 nm, and 1000 nm respectively. In other words, the ?/4 multilayer films 302 to 304 reflect near infrared light.
