  • Frequency generator
    Patent number: 5260619
    Abstract: In a frequency generator, some of connecting wire elements forming the generator coil pattern are omitted. The circuit wiring pattern is partially laid in a printed wiring board surface area located between the adjacent generator wire elements, which is not connected because the connecting wire elements are omitted. The adjacent generator wire elements not connected are connected by a conductor, which is electrically insulated from the circuit wiring pattern.

  • Position detecting device
    Patent number: 5176085
    Abstract: A position detecting device such as a needle position detecting device which detects a needle position with the aid of a rotor. In the position detecting device, the rotor and a position detecting annular member are abutted against each other, and thus the use of screws can be eliminated, and the annular member can be readily adjusted in angular position with a tool which is inserted through the holes of the rotor and engaged with the adjusting means of the annular member.
