Patent JP-H027322-A (JP)
Title: Solenoid relay
Inventor: TOGO NAOKI
IPC: H01H51/12
Filed: 1988-06-24
Abstract: PURPOSE:To relieve the impact force at the colliding time of contacts and suppress noise generation due to collision by reducing the speed near the stroke end of an armature through the action of fluid resistance of air, and thereby reducing the speed of the movable contact immediately before the movable contact contacting the fixed contact when the solenoid is to be energized. CONSTITUTION:The speed near the stroke end of an armature 23 is reduced by the use of fluid resistance of air in conjunction with armature 23. A boss 45 is formed in either of a magnetic pole and that part of armature 23 making contact with and separating from the pole, while the other member is provided with a recess 39. When the solenoid 33 is energized, the recess 39 is fitted on the boss 45, and the fluid resistance of air generated at this time will reduce the speed of armature 23 immediately before the armature 23 contact the magnetic pole. This allows reduction of the colliding noise to be generated at the colliding time of the armature with magnetic pole and colliding time of the fixed contact 26 with movable contact 25, and also the reliability in the contacting condition of the movable and fixed contacts 25, 26 will be enhanced.

CONSTITUTION:A reception signal (n-phase modulation wave) is inputted to an input terminal 1, a reference carrier is inputted from an input terminal 2 and in-phase and orthogonal components of reception signals are outputted respectively from demodulators 4, 5. The output of the demodulators 4, 5 is squared as a complex number vector in a 1st vector multiplier 61 in which the output of the demodulator 4 is used as a real part and an output of the demodulator 5 is used as an imaginary part, and the output of the (k-1)th vector multiplier 6(k-1) and outputs of the demodulators 4, 5 are multiplied in the k-th vector multiplier 6k. Thus, the output of the demodulators 4, 5 is subjected to n's power calculation by n-set of vector multipliers 61-6n as complex number vectors and a phase error multiplied by a factor of (n) is obtained. Thus, the phase error is detected without needing any complicated circuit such as an expected value detector.

Title: Automatic focus adjusting device
Inventor: ASAKURA HIROYUKI
IPC: G02B7/32
Filed: 1985-07-18
Abstract: PURPOSE:To reduce flare light beams projected to an object from a light emitting element and malfunction due to the uneven reflectance distribution of the object subjected to automatic focus adjustment by arraying a projector, a semi-transparent mirror and a photodetector in the direction of a base. CONSTITUTION:When light is projected to the object from the optical axis of an image pickup lens 1 through the semi-transparent mirror 4, the emitted light out of a projection lens 3 passes through an aperture decided by the width of the semi-transparent mirror 4, and a projected light beam is limited in the vicinity of the center of the optical axis. Some part of peripheral light beams such as the flare light beam 21 is kicked out, and the luminous energy is reduced as it becomes far away from the optical axis. Accordingly, the light beam is passed through the semi-transparent mirror first of all, whereby the luminous energy of the flare light beam 21 existing in the base direction can be reduced. When the reflected infrared light beam projected to the object is image-formed on a photodetecting element 6 through a photodetecting lens 5, the flare light beam not kicked out in the opening 22 of the semi-transparent mirror 4 in the direction where it intersects orthogonally with the base length is not detected except in the vicinity such as a light emitting part 20, because the aperture of the light receiving element 6 is long in the base length direction and short in the direction intersecting orthogonally with the base length.
