IPC: B66D1/54
Filed: 1989-11-14
Abstract: PURPOSE:To prevent over-winding and over-delivery as well by detecting over- winding to and/or over-delivery from a winch drum, and thereby making switch- over of an over-winding prevention switch-over valve and/or an over-delivery prevention switch-over valve. CONSTITUTION:When over-winding in rope winding to a drum 4 is detected by a detector 40, No.1 pilot deck valve 36 is brought into a reverse flow check condition by an over-winding prevention switch-over valve 38 so that oil flow to a winding oil pipe 28 is blocked. Even if a winch manual switch-over valve 14 is therefore switched over to the winding side, oil flow to the winding direction is blocked so that over-winding is thereby prevented with the exception that delivery can be made. When over-delivery is detected by a detector 41, No.2 deck valve 37 is brought into a reverse flow check condition by an over- delivery prevention switch-over valve 39, oil flow to an oil delivery pipe 33 is blocked so that the rope can be winded but is prevented from being excessively delivered. And when a normal condition is restored, the rope can thereby be winded and/or delivered normally.

Title: Dielectric filter
Inventor: IMAI NOBUAKI
IPC: H01P1/212
Filed: 1988-11-21
Abstract: PURPOSE:To prevent signal components other than those having a desired frequency from passing through a dielectric filter by making the shape of at least one of plural dielectric resonators electromagnetically coupled with a pair of transmission lines having limited lengths to desired extents different from those of others. CONSTITUTION:The shape of at lest one 272 of plural dielectric resonators 27 electromagnetically coupled with a pair of transmission lines 13 and 15 having limited lengths is made different from those of other dielectric resonators 271 and 273. As a result, resonance in higher-order modes which are different from a basic mode is suppressed, whereas resonance frequencies in the basic mode coincide with each other. When such dielectric filter is used, frequency components of input signals transmitted through one transmission line 13 in the vicinity of the frequency coincident with the resonance frequency of the resonators 27 are not reflected, but passed and outputted to the other transmission line 15. Therefore, the signal component of frequencies (resonance frequencies of higher-order modes) which are different from the resonance frequency are not passed, but reflected.
