Title: Optical space transmission device
Inventor: SHIGETA JUNJI
IPC: H04B10/11
Filed: 2000-04-10
Abstract: PROBLEM TO BE SOLVED: To always maintain an optimum light receiving diameter, even if a distance to an opposite device is changed. SOLUTION: A main signal inputted ot a main signal input part 20 which is converted into a optical signal in an electric/optic conversion part 23, is outputted to a transmission beam angle variable part 28 through a beam spread angle control lens 26 and is outputted to the opposite device through lenses 29 and 30. An optical beam passes through the 1/4 wavelength board 43 of the opposite device and is reflected in a reflection part 45. Reflected light returns to a transmission part. In the signal, which is electrically converted in a position detection light-receiving element 32, a distance detection signal is extracted and is outputted to a phase comparison part 34 in a filter part 33.  A phase difference between the distance detection signal inputted from the filter part 33 and the distance detection signal generated in an angle difference/distance detection signal generation part 21 is converted into a voltage signal. A beam spread angle variable control part 35 analyzes the distance between the devices based on voltage information inputted from the phase comparison part 34 and frequency information on the distance detection signal which is previously inputted, moves the beam spread angle control lens 26 in the direction of an optical axis and controls a transmitted optical beam spread angle to an optimum value.

IPC: F02F5/00
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a piston ring coping with a high Pmax, which hardly causes separation of a coat by eliminating a high surface pressure state in an abutment part at an early stage. SOLUTION: This piston ring 1 is provided with an outer peripheral sliding surface 3, an inner peripheral surface 4 counterposed to a piston, and one abutment part 2 parting the substantially circular form in the radial direction.
