Title: Trouble detecting circuit for adder
Inventor: KAGA TAKAHIKO
IPC: G06F7/499
Filed: 1986-03-07
Abstract: PURPOSE:To contrive the diagnosis of an adder by providing the input selecting circuits to both inputs of the adder for test of this adder and supplying the output of a counter to said both inputs of the adder to perform comparison between the output of the adder and the value obtained by doubling the output of counter. CONSTITUTION:Both selecting circuits 21 and 22 are switched to check whether an adder has a trouble or not while the adder 5 is not used. Thus the output of a counter 1 is sent to both inputs of the adder 5. The output of the counter 1 is doubled and delivered through a 1-bit left shifter 3. Here the output of the adder 5 must be double as much as the output of the counter 1 as long as the working of the adder 5 is normal. Then the output of the adder 5 must be equal to the output of the shifter 3. Thus it is possible to diagnose the adder 5 by comparing both outputs of the adder 5 and the shifter 3 through a comparator 4. The counter 1 is actuated by the clock that is used also for the actuation of the adder 5.

Abstract: PURPOSE:To facilitate the formation of the curved part of an optical fiber at a radius of curvature of several mm or below without increasing passage losses by stretching a part of the optical fiber and forming the curved part in the part where the diameter of the stretched part changes gently. CONSTITUTION:The curved part 2 of the single mode optical fiber 1 is so constructed that the optical fiber 1 is partly stretched and the gently changing diameter part of the stretched part forms a part or the whole of the curved part 2. Namely, the radius of curvature can be drastically decreased while an increase in the passage losses is suppressed only by forming the gentle and smooth stretched part. Then, the single mode optical fiber 1 can be bent at an extremely small curvature while the increase in the light losses is suppressed, and therefore, the surplus length treating part of the single mode optical fiber 1 or its juncture, etc., is diminished and a degree of freedom is added to a wiring shape. In addition, the single mode optical fiber wiring relieving the restriction on the curvature is practically obtd.
