摘要： An ignition coil for internal combustion engine includes: a center core disposed on an inner side of a primary coil and a secondary coil and a side core disposed on an outer side of the primary and secondary coils whose one end face abuts on one end face of the center core and the other end face abuts on the other end face of the center core via a magnet. The side core is formed of a plurality of side core portions obtained by dividing laminated magnetic steel plates at different positions in a longitudinal direction thereof and has a superimposed portion in which the magnetic steel plates of the adjacent side core portions mutually superimpose between the different positions in the longitudinal direction. It thus becomes possible to provide an ignition coil for internal combustion engine capable of suppressing an increase of magnetic circuit resistance markedly without deteriorating assembly workability.

摘要： Disclosed is a zonal range finding apparatus for determining whether an object is located within a first range of distances from the apparatus or a second range of distances from the apparatus. The apparatus includes a radiation projecting device for projecting a beam of radiation toward an object, and a radiation receiving device for receiving radiation by the object. The receiving device is disposed at a distance of a predetermined base line length from the projecting device and having a radiation sensor which produces an electrical output corresponding to the received radiation. Further, a circuit determines, on a basis of the sensor output, whether the object is located within the first or second range. Also disclosed is an automatic focus adjusting device of an image forming optical system which uses an operation member which is manually displaced up to a position at which the member is displaceable in accordance with the distance signal from a distance measuring device with the member provided at the lens barrel of a camera.
