Filed: 1990-06-08
Abstract: PURPOSE:To obtain high resolution and a large measurement stroke by providing a 1st optical fiber group and a 2nd optical fiber group of specific width which are coupled optically with a pair of a light emitting element and a light receiving element at one end so that the other end surfaces face each other at an interval, and providing a necessary measuring element of specific size which is coupled with a body to be measured and movable between the 1st 2nd optical fiber groups. CONSTITUTION:The other end surfaces of the 1st optical fiber group 12a and 2nd optical fiber group 12b which are coupled optically with the pair of the light emitting element 2 and light receiving element 3 at one end face each other at the interval to form a gap 15. The measuring element 16 which couples with the object of measurement is inserted into the gap 15 from an opening part and arranged freely movably in the vertical direction. The section of the optical fiber group 12a nearby the gap 15 is in such a trapezoidal shape that the width perpendicular to the moving direction of the measuring element 16 increases gradually at a specific ratio from one end part to the other end part. Further, the size of the measuring element 16 in the moving direction becomes much smaller than the vertical size of the opposition surface between the optical fiber groups 12a and 12b and the displacement, position, etc., of the body to be detected are detected; when coated optical fibers are decreased in diameter and increased in number, the small-sized photoelectric displacement sensor which has the high resolution and large measurement stroke is obtained without providing a light emitting and a light receiving element additionally.

IPC: H02M3/28
Filed: 1988-06-20
Abstract: PURPOSE:To prevent a transformer against saturation by reducing the duty of a driving pulse of a switching transistor in starting the power supply and by extending the OFF-time for switching. CONSTITUTION:A DC/DC converter is composed of a DC power source 10, a transformer 20, a switching transistor(Tr) 30 and a DC smoothing circuit 40 to feed the current to a load 50. An overcurrent monitoring circuit 70 inputs the output of a current transformer 21 provided to the primary winding Np of the transformer 20 and monitors the current. In putting the power supply to work, when the overcurrent is detected, a pulse width control is performed in synchronization with the output clock of a PG 63 with a control circuit 60. On the other hand, until the overcurrent is detected by the overcurrent monitoring circuit 70, H-level signals are outputted, which are then inputted into an FF85. A clock output through 1/2 frequency demultiplying circuit 80 is also inputted and the pulses of reduced duty is outputted from an AND circuit 90. The output of this AND circuit 90 is added to the Tr 30, so that constant output voltage is supplied to the load 50.

Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To improve sensitivity and detecting precision by pressing a push button against the elastic member of a mechanical key switch by a weight, and performing a switch-on operation. SOLUTION: A weight 3 is mounted on a push button 11 by press fitting a mounting shaft part 13 to its mounting hole part 14.

Then, the member 10 is reversed to make contact with a first contact 6, and the contact 6 and a second contact 7 are mutually connected through the member 10 and laid in switch-on state. The switch 1 is quickly reacted by the weight 3 in this way, whereby the sensitivity is enhanced, and the detection of acceleration can be precisely performed.  The weight of the weight 3 is changed, or its center-of-gravity position is changed, whereby the further improvement in detecting sensitivity and the change and regulation of sensitivity can be performed.
