Patent CA-2069369-A1 (CA)
Inventor: PEACH ROBERT C
IPC: H03H9/02
Filed: 1992-05-25
Abstract: A filterbank using surface acoustic wave technology and has a plurality of filters.  Each filter has an input transducer and an output transducer.  The input transducers are connected in parallel to a single matching circuit.  The output transducers each have a separate matching circuit. The transducers are formed by a thin film of aluminum pattern on a piezoelectric substrate. The input transducers all have the same structure and the output transducers all have the same structure, though that structure is different from the input transducers. The only difference between the transducers of each filter is the location of electrode breaks for each electrode.  A weighting function of the transducers is scaled and biased to provide a constant impedance across the bandwidth of the filterbank and to equalize the output amplitudes and capacitances of the output transducers.  This produces a continuous level response across the bandwidth of the filterbank. Previously, while a continuous level response was theoretically achievable, it cannot be achieved in practice.

Title: Trailer with combined towing and centering means
Inventor: MORIN ANDRE
IPC: B60D1/14
Filed: 1990-12-06
Abstract: ABSTRACT      The trailer including a main towing device movable by articulation and sliding, from top to bottom, from front to rear and from right to left to facilitate hitching the trailer to the back of a motor vehicle using a conventional ball-type trailer hitch in conformity with international road regulations.  The towing device includes a flexible fixing device to fasten the front part of the  trailer to the roof of the motor vehicle through a transverse and vertical centering device which slides from front to rear through sliding rails mounted on a roof-rack, or, as an alternative, through sliding rails mounted underneath the front part of the trailer.  The combination of the devices enables rapid coupling and uncoupling of the trailer and the motor vehicle, the locking of the sliding motion of the main towing  device  in  road-ready  position  being  automatically performed by means of locks.
Patent CA-2071592-A1 (CA)
Inventor: FUJI HIROSHI
IPC: G11B11/105
Filed: 1992-06-18
Abstract: In a magnetic head driving circuit according to the present invention, switching devices are turned on/off in response to a recording signal, thereby inverting a drive current to be applied from direct current power sources to a magnetic head coil. Switching devices are connected in parallel with dummy loads serially connected to the direct current power sources. In response to theswitching of the switching devices, the magnetic head coil and a dummy load alternately function as a load of each auxiliary coil. The impedance of each dummy load is set to be equal to the impedance of the magnetic head coil, thereby fixing the total load of each of the auxiliary coils at any time. Since a balance can be established between a value of a drive current in one direction and that of a drive current in the opposite direction, it is possible to reduce jitter of a recording mark and provide abrupt rises and falls in the drive current.

Filed: 1992-05-18
Abstract: ABSTRACT OF THE INVENTION           The disclosure concerns a core box having a drag and a cope forming a mold cavity for forming a sand base core. This sand is injected into the cope and the air in the cavity is vented through vents remote or spaced away from where the sand is inserted. These vents are usually in the drag, but may also be in the cope. In each vent adjacent the cavity is a cylindrical cup-shaped plug having slotted perforations in its bottom narrower than the diameter of the sand grains. The diameter of this perforated vent plug is at least 50% greater and preferably at least twice the width of the cavity, slot, or groove at the vent whereby air can be vented along the cavity. Furthermore, the plug having the perforations may be contoured to the groove or that portion of the cavity in which the vent is located so that air can also be vented from the sides of the cavity or groove. These plugs are held in place by sleeves that contact the rim of the cup and extend to the outside of the mold where the sleeves are held in place by overlapping washers or heads of bolts screwed into the mold.
