Patent JP-S6421606-A (JP)
Title: Adaptive loop control system
Inventor: TAKEUCHI ISAO
IPC: G05B13/00
Filed: 1987-07-17
Abstract: PURPOSE:To prevent delay in the response of loop and loop control instability by multiplying a voltage in response to the low/high detected loop gain with respect to the design value with a control error voltage of the loop thereby controlling properly the control error voltage. CONSTITUTION:An output voltage of a nonlinear element 2 is fed to a code detector 6. If the loop gain is lower than the design value, an output of an integration device 7 is increased positively or negatively. On the other hand, if the loop gain is higher than the design value, the output of the integration device 7 is close to zero. The output of the integration device 7 is detected by using a square device or an absolute value circuit 8 and its output is amplified (9), and a prescribed bias voltage is added to an adder 10 to adjust the loop control error voltage. Thus, when the loop gain is smaller than the design value, the control error voltage of loop is large and when the loop gain is higher than the design value, the loop control voltage is small thereby preventing the delay in the loop response and the loop control instability.

Title: Bobbin for transformer
Inventor: WATANABE TAKUMI
IPC: H01F27/32
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To secure a required creeping distance without increasing the thicknesses of the intermediate flange of a bobbin for transformer around which a coil is wound by utilizing winding grooves formed between each flange by forming a recessed or projecting rib on the intermediate flange in the length direction of the flange. SOLUTION: A bobbin 1 has winding grooves 3 formed among flanges 2 which are formed at prescribed intervals and used for winding a coil 4. Since a traverse section is required when the winding 4 is wound around the bobbin 1 by utilizing the grooves 3, a traverse section 5 is formed on the intermediate flange 2. The winding 4a shifts to the adjacent winding groove 3 through the traverse section 5. Then a recessed rib 6 is formed on the traverse section 5 perpendicular to the creeping distance. Consequently, the creeping distance is elongated by the recessed amount of the rib 6. When the thickness of the intermediate flange 2 is not changed, in addition, the performance of the bobbin 1 can be improved by increasing the number of turns of the coil 4 in one winding groove 3.  When the bobbin has a sufficient performance, on the other hand, the creeping distance can be maintained by reducing the thickness of the intermediate flange.
