摘要： A transmission line with a bending portion is provided, which line comprises any one of a coplanar line, another coplanar waveguide line formed on the dielectric substrate under which a ground layer is provided and a coplanar strip line. A chamfered portion is provided on the outer angular portion of the bending portion of the signal wiring conductor and a triangular conductor is disposed to an inner angular portion thereof. Given that length of the chamfered portion is defined as a, and length of the wiring edge side of the triangular conductor is defined as b and width of the signal wiring conductor is defined as c, it is arranged such that a is greater than b+c×square root of 2. Thereby, a transmission line or an optical module of smaller reflection loss at the bending portion thereof and of improved high-frequency characteristics is provided.

摘要： In an optical coupling apparatus, an optical isolator and an optical fiber are arranged inside a pipe of a side surface of a package. A distal end of the optical fiber is arranged within a range of 3.0 mm from an inner/outer surface of the side surface of the package and a distance from a laser diode to the distal end is within a range from 3.5 to 7.5 mm. Distance from the inner side surface of the package to a Peltier device is within a range of 6.0 mm. A metallize pattern film applied to a terminal substrate of the package and the Peltier device are connected through wiring bonding and a connection position is closer to the optical fiber than a lead terminal provided to the terminal substrate of the package that corresponds to the Peltier device.

摘要： An object of disclosed technology is to control lasing wavelengths so that a wavelength shift does not occurs. Another object is to permit wavelengths of a light source for wavelength division multiplexing optical-fiber communication system to be variable in response to an ITU-TS grid. A means for achieving the objects is as follows: locating an etalon in a light path of diode laser light, which is a parallel plane wave changed by a collimator lens; generating a wavelength error signal from a difference between both of divided pieces of light from transmitted light or reflected light; and locking a wavelength of a diode laser device according to the wavelength error signal.

摘要： An apparatus for simultaneously reading images on both sides of the document sheet as the sheet having images on both sides is moved through the apparatus, one side read by a CCD sensor and the other side read by a contacted image sensor. An image synthesizing unit synthesizes image data from the CCD sensor and image data from the contacted image within one cycle of main scanning by the two image reading units. Furthermore, image processing circuits in the subsequent steps perform specific modes of processing on the data within one cycle of main scanning. That permits simultaneous reading of both sides of the sheet document without reducing document reading speed and expansion of the image processing unit.
