Title: Damper disk
Inventor: FUJIMOTO SHINJI
IPC: F16H45/02
Filed: 1988-04-25
Abstract: PURPOSE:To prevent an outer supporting part from being largely deformed in the radial direction due to centrifugal force out of a spring by supporting the circumference of this outer supporting part with a cylindrical part of an input plate. CONSTITUTION:In assembly operation, when a hold plate 9 is built in the inner part of an outer cylindrical part 30 of an input plate 6, a supporting part 22 and a part of this hold plate 9 in the vicinity are divided by a notch 41, so that the supporting part 22 is elastically deformable inward in the radial direction. Therefore even if an outer diameter of the supporting part 22 in a state prior to assembly is set to be somewhat larger than an inner diameter of the input plate cylindrical part 30, the hold plate 6 is elastically deformed and the supporting part 22 can be assembled in an inner part of the input plate cylindrical part 30, and consequently the supporting part 22 can be fitted in an inner circumference of the cylindrical part 30 in a cohering state.

Title: Method for controlling tension for winding of optical fiber
IPC: G02B6/00
Filed: 1992-03-27
Abstract: PURPOSE:To eliminate an increase in the loss of under-wound bobbin by making the lateral pressure applied to the optical fiber of the under-wound bobbin less than the lateral pressure which causes the optical fiber to generate the loss increase. CONSTITUTION:Winding tension is decreased from T1 to T2 as a bobbin take-up radius Ri increases so that when the winding ends, the lateral pressure applied to the optical fiber of the under wound bobbin is less than the value Pc of the lateral pressure which causes the optical fiber to generate the loss increase. Namely, contact pressure (lateral pressure) P applied between the optical fiber of a 1st layer and a bobbin is the sum of its lateral pressure P1 (only between the optical fiber of the 1st layer and the bobbin) and the whole lateral pressure of the optical fiber wound even in several layers. Therefore, when the number (n) of winding layers and the take-up tension T1 in the beginning of winding are determined, the value P is calculated, the take-up tension Tn at the end of the winding with which the value does not exceed the Pc is found, and the tension is varied stepwise from T1 to Tn, so that no increase in the loss of the under-winding of the optical fiber is generated.

Abstract: PROBLEM TO BE SOLVED: To prevent diode characteristics from deteriorating by collecting an acceptor impurity near a damage region and preventing a p<+> /n<+> junction from being formed in a succeeding annealing treatment, by providing the damage region artificially around an n-type active region. SOLUTION: A sputter ZnS film 14 is deposited in a lattice near an n<+> -type region 13 by the master sputtering method. A damage region 15 is formed directly below the sputtered ZnS film 14 due to a physical damage by sputtering in this case and a film stress of the sputtered ZnS film 14. Then, after an ZnS surface protection film 16 is provided on an entire surface using the electron heating deposition method, an annealing treatment is performed in an N2 atmosphere. In this case, an acceptor impurity 21 included a p-type HgCdTe layer 12 travels near the damage region 15 and is accumulated there. In this manner, by accumulating the acceptor impurity 21 at the damage region 15 being formed artificially, the reduction in diode characteristics can be prevented.

IPC: H02P7/06
Filed: 1980-07-29
Abstract: PURPOSE:To reduce the overshooting of a speed control signal by a method wherein the capacitor on the feedback circuit of the arithmetic operational amplifier on a compensating circuit is short-circuited in proportion to the output voltge of the compensating circuit. CONSTITUTION:A speed error detector 11 gives the difference between a speed command signal and a speed feedback signal to the compensating circuit 12. The compensating circuit 12 performs a proportional and integral control using the arithmetic operational amplifier 31, the feedback resistors 33 and 34 and the capacitor 32, and supplies the above to a servomotor 14 through the intermediary of a power amplifier 13. When the output voltage of the compensating circuit 12 is increased, a wind comparator 21 outputs a positive voltage, with which the capacitor 32 is short-circuited by conducting a switching element 22 and the gain of the  arithmetic operational amplification circuit is reduced. Through these procedures,  the overshooting of the speed controlling signal is reduced and the stabilized speed control of a DC servomotor can be performed.
