Patent JP-H02287104-A (JP)
Title: Laser length measuring instrument
Inventor: IKEZAWA KATSUYA
IPC: G01B9/02
Filed: 1989-04-27
Abstract: PURPOSE:To correct phase distortion without requiring any strict alignment and to improve the measurement accuracy by using self-pump type phase conjugate mirrors for two reference and length measuring reflecting mirrors. CONSTITUTION:The self-pump type phase conjugate mirrors(PCM) are used as the reflecting mirror 21 on a reference optical path side and the reflecting mirror 22 on a length measurement optical path side. When the self-pump type phase conjugate mirrors are used, reflected light returns in the same direction with incident light. Consequently, no strict alignment is required for an interfero- meter and phase distortion generated on the way of an optical path is corrected, so light having no phase distortion causes interference when multiplexed with measurement light on a beam splitter and detected by a photodetector 7, thereby improving the measurement accuracy.

Title: Switched capacitor filter
Inventor: YASUDA SUSUMU
IPC: H03H19/00
Filed: 1986-05-12
Abstract: PURPOSE:To decrease the DC offset without changing the transmission characteristic with the same total capacitance as that of a conventional filter by dividing the capacitor of a bicut type SCF into two groups and changing independently the unit capacitance of each group. CONSTITUTION:Plural switches and capacitors, and two operational amplifiers constitute the bicut switched capacitor filter. The capacitors constituting the filter is divided into capacitors 17, 20, 23, 24, 19 of a group using a capacitance BC1 and capacitors 21, 22, 15, 16, 18 of a group using a capacitance DC0 as a unit. Through the constitution as above, the unit capacitances are selected independently for each group without changing the transmission characteristic. In selecting the unit capacitance C1 as a half of the unit capacitance C0 in this grouping, the DC offset is reduced to 60% of a conventional offset.

Title: Production of polarization maintaining optical fiber coupler
Inventor: KOSHIBA YOSHIAKI
IPC: G02B6/28
Filed: 1991-04-12
Abstract: PURPOSE:To allow the effective use of panda type polarization maintaining optical fibers for optical measurement or as optical fiber sensors by fusing and stretching the fibers which are reduced in diameter down to a prescribed shape by an etching agent. CONSTITUTION:The panda type polarization maintaining optical fibers 1 are used and are immersed into a satd. soln. mixture composed of hydrofluoric acid and aq. ammonium fluoride soln. The panda type polarization maintaining optical fibers 1 are made into the elliptic optical fibers 1' having 60mum major diameter (a) and 40mum minor diameter(b). While the panda type polarization maintaining optical fibers 1', 1 reduced in the diameter in such a manner are heated together, the fibers are subjected to the fusing and stretching treatment under tension. The branching ratio does not largely vary in an X direction (X polarization) and Y direction (Y polarization) in such a case and, therefore, the arbitrary setting of the branching ratio is possible. Such fibers are effectively utilziable for optical measurement or as the optical fiber sensor.
