Title: Latch-type electromagnetic valve
Inventor: MIZUTANI KEIICHI
IPC: F16K31/08
Filed: 1998-04-21
Granted: 1999-06-01
Abstract: In a latch-type electromagnetic valve (1) which uses a permanent magnet (3) to attract a plunger (2) and maintain an open valve state, which passes electricity through an electromagnetic coil (6) to generate magnetic lines in an opposite direction, and which uses the biasing force of a spring (7) to lower plunger (2), if it is desired to enhance the flow of magnetic lines from the electromagnetic coil (6), the area of the permanent magnet (3) is enlarged. However the area of the permanent magnet (3) is enlarged. However, the greater magnetic force of the permanent magnet (3) makes it difficult to close the valve, or the plunger (2) will be pulled away upwardly form the close valve state and cannot be maintained in the close valve state. To this end, a bypass portion (42) is designed to contact a magnetic core (4) and a frame (5) so that a portion of the magnetic lines from the permanent magnet (3) will not flow to the plunger (2) and will instead bypass the same. The magnetic force of the permanent magnet (3) acing on the plunger (2) is thus smaller.

Abstract: A fiber reinforced composite spar for a helicopter rotor blade including upper and lower sidewall regions and forward and aft conic regions. Constant width crossplies and unidirectional plies are stacked and arranged to form crossply and unidirectional laminates. The crossply laminates have end portions extending into the forward and aft conic regions to form a staggered distribution of structural butt joints and slip plane interfaces therein. The composite spar in manufactured via a vacuum forming technique which may include assembling the composite laminates in complementary molds or forming the composite laminates directly over an inflatable mandrel assembly. Regarding the latter, a spar forming apparatus is used to position and manipulate the mandrel assembly as composite laminates are laid. The spar forming apparatus includes first and second pedestal supports being suitably configured so as to facilitate formation of the butt joints in the conic regions of the composite spar. The pedestal supports are movable from a first orientation to facilitate lay-up of composite laminates over the mandrel assembly, to a second orientation to facilitate transfer of the mandrel assembly from one to the other of the pedestal supports. The spar forming apparatus further includes an electromagnetic coil system comprising at least one electrically activated coil and a controllable power source. The electrically activated coils are disposed in combination with each of the pedestal supports and the controllable power source selectively energizes the electrically activated coils to effect a magnetic clamping force between the mandrel assembly and one of the pedestal supports. Such electromagnetic coil system accurately positions the inflatable mandrel assembly during lay-up of the composite laminates and effects transfer of the mandrel assembly.

Title: Hybrid image-reject receiving apparatus and method
Inventor: HUANG JIA-CHI
IPC: H04B1/10
Filed: 1999-03-15
Granted: 2001-03-01
Abstract: A novel hybrid image-reject receiver architecture is disclosed. We first modify Hartley image-reject receiver and obtain two output signals which both consist of a desired signal and an image signal. One output signal contains a stronger desired signal and a weaker image signal and the other output signal contains a stronger image signal and a weaker desired signal. The two output signals are then sent to a digital desired/image signal separator to obtain a baseband output signal. The IRR of this baseband output signal is the cube of the IRR obtainable by a Hartley image-reject receiver. At the same time, we can cascade multi-stages of the desired/image signal separators to achieve further gain on IRR. The architecture greatly enhances the image rejection ratio (IRR) and relaxes the requirements of matching for analog devices.
