Title: Waveguide type photo-displacement sensor
Inventor: TAKAGI JUNICHI
IPC: G01S17/06
Filed: 1985-07-01
Abstract: PURPOSE:To make a sensor of longer distance of displacement measurement and available for identification of direction of the displacement, by installing two inclined reflecting surface on the specimen, mans for converting a signal light into parallel beams and phase-shifting means of wave guide light respectively. CONSTITUTION:Asymmetric X dividing type photo-waveguide paths 10, 12 are formed, a beam of light of waveguide paths 14, 24 are reflected as the reference light by reflecting films 5, 6, beams of light of waveguide paths 13, 23 are reflected as a signal beam by a movable mirror 4 provided with two inclined reflecting. Surfaces, and an output beam of intensity depending on a phase difference of the reflecting beam is fed out from waveguide paths 12, 22. As phase-shifting grooves 25 are constructed in the waveguide 24, a phase deviation is created between the output beams of the waveguide paths 12 and 22 enabling identification of the direction of displacement of the mirror 4 and by deviation of the incidence angle theta onto the mirror 4 enables identification of difference of their light paths. A rod lens 3 conducts conversion into parallel orientation of the beams and intensity of light can be maintained constant regardless the displacement of the mirror 4 and the distance of displacement measurement can be increased and the direction of displacement can be identified also.

Title: Through hole circuit board
Inventor: KOBAYASHI SHINJI
IPC: H05K3/42
Filed: 1989-06-07
Abstract: PURPOSE:To enable execution of soldering connection of high reliability by a method wherein the whole or a part of the periphery of a corner part on the surface side whereon an inserted component is disposed is covered with a resist material. CONSTITUTION:The whole or a part of the periphery of the corner part, of a through hole 3 on the surface side whereon an insertion-type component 6 is disposed is covered with a resist material 7. When the whole periphery of the corner part on the surface side whereon the inserted component 6 is disposed is covered with the resist material 7, accordingly, soldering is not made on one surface side of a substrate 1 and fixation is made only on the other surface side. Therefore the effect of shrinkage of a lead 8 due to thermal expansion is not produced thereon. Even when the corner part of the through hole is covered only partly with the resist material 7, a solder crack 11 does not lead to an electrode crack 12 and does not cause discontinuity in the through hole 3 even if the solder crack occurs in a soldered part 9, since no soldering is made on the corner part of the through hole covered with the resist material 7. According to this method, soldering connection of high reliability can be attained.
