A keylock collar 2 is constituted to include a square cylinder portion 21 on its body front side half and a cylindrical portion 22 on its body back side half. The circular outer circumference 26 of the cylindrical portion 22 has eleven ridges 27 formed at an angularly equal spacing to bulge radially outward. When an ignition key is turned to a lock position and pulled from the keyhole, a lock key 19 is protruded toward the axis of a steering shaft 13. As a result, the leading end of the lock key 19 comes into engagement between the side faces 271 and 271 of the adjoining ridges 27 and 27 of the keylock collar 2 so that the steering shaft 13 is fixed with respect to a column 11 thereby to block the rotation of the steering shaft 13.

Also disclosed is a surface acoustic wave device characterized in that the metalized ratio g/p, which is the ratio of the width of an electrode and the intercentral distance between the adjacent electrodes in an irregular pitch electrode group, is varied between 0.1 to 0.4 or between 0.6 to 0.9.
摘要:
A surface acoustic wave (SAW) device comprises a piezo-electric surface acoustic substrate, and plural sets of input/output interdigital electrodes disposed on the substrate. A phase shifter is provided between a sending electrode and a reflecting electrode included in the input or output interdigital electrodes for producing an electrical phase difference to implement a unidirectional electrode. The sending electrode and the reflecting electrode are mutually connected through the phase shifter including two pure reactance elements serially connected between the sending and the reflecting electrodes and a pure reactance element connected to the junction between the two serially connected reactance elements so as to form a T-circuit. When the two serially connected pure reactance elements are selected equal to each other, the operating frequency band is broadened. The phase shifter includes no ohmic resistance and thus is lossless.

摘要:
A group-type unidirectional surface acoustic wave filter composed of sending electrodes, reflecting electrodes and meander electrodes constituted by interdigital electrodes, respectively. As a phase shifter of the filter, a capacitive element is used. The geometrical configuration of the meander electrode is determined in accordance with geometrical phase difference. The filter enjoys low insertion loss with a simplified structure.
