Abstract: A parallel running vehicle detecting apparatus is provided, which includes a first distance sensor for detecting distance of an object in a first detection area on a rear lateral side of a vehicle, a second distance sensor for detecting distance of an object in a second detection area, a parallel running vehicle detector for detecting a parallel running vehicle based on detections of the first and second distance sensors, and a storage for storing a detection distance history of the second distance sensor. The parallel running vehicle detector is provided with multiple determination conditions for determining whether the object detected by the first distance sensor is the parallel running vehicle, and changes the parallel running vehicle determination condition based on the detection distance history stored in the storage.

Abstract: The present invention is related to an optical communication module for transmitting high frequency signals (e.g., 10 Gbit/s and higher data rates) between an optical element and an external circuit. In an illustrative embodiment, the optical communication module includes signal transmission lines and ground lines formed on a ceramic substrate, a flexible wiring board, and a printed circuit board. The widths of the signal lines and the ground lines vary, as well as the spacing between the signal and ground lines. This facilitates characteristic impedance matching among the signal lines to within about 50?.

Abstract: A ceramic substrate is provided through a stem of a can-package, the desired number of wirings including the high speed signal wirings are formed on this ceramic substrate and the necessary electronic components other than a light-emitting/photosensitive element such as driver LSI and amplifying LSI or the like are also accommodated within the can-package.

Abstract: An ultra-thin resin molded semiconductor device of high reliability with low cost and with easy repair at time of mounting. A plurality of these semiconductor devices are stacked to provide a semiconductor module which has a higher function than semiconductor devices in the same volume, and a card type module utilizing assembled by the stacked semiconductor module is provided. In manufacturing the semiconductor module, an extremely thin lead frame and an LSI chip are directly connected together, and the mirror surface of the LSI chip is exposed by using a low viscosity epoxy resin to have a thin molding. The mirror surface is grinded to have a further thin thickness of the whole structure of the semiconductor device. A part of the lead frame is formed as a reinforcing member, a heat radiation path, a light shielding part for shielding the LSI from harmful light beams, or a positioning base for mounting a substrate.

Abstract: A highly water-absorbing but less water-soluble hydrogel is produced by polymerizing at least one hydrophilic ethylenically unsaturated monomer, e.g., ethylenically unsaturated carboxylic acid, ethylenically unsaturated sulfonic acid, or derivatives thereof, in the presence of a specific difunctional compound, e.g., polyethyleneglycol diglycidyl ether, polyethyleneglycol diacrylate, etc.
