Abstract:
An acoustic wave device includes an acoustic wave element formed on a piezoelectric substrate, and a terminal that makes an electric connection with an outside of the acoustic wave device. The terminal has a protrusion electrode having a side surface coated with a coating film having a non-coating portion.
Abstract:
An image forming apparatus includes a scanner section, an image forming section, and a functional unit. The scanner section is configured to read image information by scanning an image bearing side of a document sheet. The image forming section is located above or below the scanner section with a space section provided therebetween and is configured to perform image formation processing on a recording medium based on the image information read. The space section has at least one open vertical side. The functional unit is removably fitted into the space section through the open side.
Abstract:
A duplexer that includes: a transmission filter and a reception filter that are connected to a common terminal; and a reactance circuit that is connected to at least one of the transmission filter and the reception filter. The reactance circuit includes an insulating substrate, lumped-constant inductors, and at least one capacitor. The lumped-constant inductors and the capacitor are formed directly on the surface of the insulating substrate.
Abstract:
Disclosed is a power generating module which generates electric power by using fuel, including: an accommodating section to accommodate a fuel container to store fuel; a power generating section to perform power generation by using the fuel in the fuel container; and a controlling section to allow, after an amount of the fuel in the fuel container accommodated in the accommodating section becomes less than a predetermined amount necessary for the power generation in the power generating section, at least a portion of a by-product generated in a process of the power generation in the power generating section to be collected into the fuel container containing less than the predetermined amount of the fuel.
Abstract:
A solid state image pickup apparatus that can read a signal charge correctly is provided. A peripheral area of a photoelectric conversion area 400 where photoelectric conversion pixels are formed has common output line forming areas 401a and 401b where common output lines for transmitting electric signals from the above described photoelectric conversion area. A plurality of inner lenses are formed in a constant pitch in an inner lens forming area 402 including a photoelectric conversion area 400 and the above described peripheral area. A plurality of inner lenses located in the outer peripheral part of the inner lens forming area 402 are arranged not to overlap with the common output lines.
Abstract:
An acoustic wave device includes a piezoelectric substrate, a first dielectric film provided on the piezoelectric substrate, electrodes that are provided on the first dielectric film and excite an acoustic wave, and a second dielectric film that is provided so as to cover the electrodes and is thicker than the electrodes.
Abstract:
A SAW filter includes a first SAW resonator having a pair of terminals and a predetermined resonance frequency (frp), the first SAW resonator being provided in a parallel arm of the SAW filter. A second SAW resonator has a pair of terminals and a predetermined resonance frequency (frs) approximately equal to a predetermined antiresonance frequency of the first SAW resonator (fap). The second SAW resonator is provided in a series arm of the SAW filter. An inductance element is connected in series to the first SAW resonator.
