Patent CA-2043387-A1 (CA)
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/1398
Filed: 1991-05-28
Abstract: An  optical  head  device  having  an  optical  system provided with at least a light source, a shaping prism, an diffracting element and a photodetector.  The light source emits light whose intensity distribution has an elliptic shape in its cross section orthogonal to the optical axis.          The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape.  The diffracting element has diffracting regions formed by at least one division line substantially parallel to a reference direction.  The light reflected from the recording medium forms an elliptic bright portion on the diffracting element.  The photodetector is divided by a plurality of division lines, at least one of which is parallel to the reference direction.  When there is no focus  error,  the  diffracting  element  diffracts  the reflected light so as to converge it on the division line substantially parallel to the reference direction in the photodetector.   For example,  when the shaping prism is adapted to shape the elliptic intensity distribution with respect to its minor axis direction, the optical system is arranged so that the major axis of the bright portion is parallel to the division line of the diffracting element.          Thus,  it  is  possible  to  suppress  offsets  in  focusing control due to wave-length variations of light.

Title: Muscle stimulator with variable duty cycle
Inventor: GRANDJEAN PIERRE-ANDRE
IPC: A61M60/882
Filed: 1990-12-04
Abstract: Apparatus and method of controlling a muscle stimulator by varying the duty cycle. The muscle stimulator is particularly adapted to a skeletal muscle powered cardiac assist system. An activity or other sensor (104) is used to determine the requirement for cardiac output. A second electrical sensor (34) is used to determine the cardiac rate. The outputs of these two sensors are employed to select a duty cycle for muscle stimulation of the skeletal muscle (22). The duty cycle is lowered for reasons of efficiency and safety during periods of very high or very low cardiac rate or body activity. The number of stimulation pulses within a burst is similarly increased when cardiac demand is high to ensure maximum contractile force of the skeletal muscle (22) during each stimulation burst.

Title: Tree root barrier combination, and method of manufacture
Inventor: ALBRECHT LEONARD N
IPC: A01G13/00
Filed: 1992-08-07
Abstract: ABSTRACT           A control barrier for preventing damage by tree roots to sidewalks and other structures is disclosed.  Unlike some previous techniques for providing such barriers the invention provides by extrusion continuous lengths of control panels which are then sheared into desired lengths, which lengths can be three feet, four feet or more without changing the size or cost of the econom-ical extrusion die.  Because the lengths can be long, the panels can be connected together in steeply stairstepped relationship and still have large overlaps and thus highly adequate connecting strengths.  The necessity for any connector elements is elimina-ted.  This is because the panels are extruded not only with root deflector elements, but with a Tee portion at one edge of each panel and a corresponding groove defining element at the other edge thereof.  The panels can be shipped without any assembly, with no chance that there will not be enough (or will be too many) connector elements for the number of panels.  Preferably, pairs of panels are preassembled with each other before shipment and storage, to reduce labor at the job site and to make a factory check to be sure that the Tees fit correctly into the grooves.

Title: Controlling apparatus for continuous electrolytic ion water producing apparatus
Inventor: ARAI KAZUYOSHI
IPC: C02F1/461
Filed: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE       A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that an excess current when the electrolyzing strength is not adjusted appropriately can be prevented with certainty and harmless electrolytic ion water can be obtained continuously from the continuous electrolytic ion water producing apparatus.  When water flows through the electrolytic cell,  it is energized by a power source circuit to electrolyze the water to obtain electrolytic ion water.   When a range change-over switch is manually operated, a dc voltage of the power source circuit is controlled in response to the range change-over switch by a control unit and a switching regulator to produce an electrolyzing voltage corresponding to the operated position of the range change-over switch.  The water is thus electrolyzed with an electrolyzing strength of the electrolyzing voltage.  During the electrolyzing operation, the electrolytic current is always detected by a current sensor, and when it exceeds a preset value and an excess current is judged,  the pulse width is decreased to automatically decrease the electrolyzing voltage and hence the electrolyzing capacity.

Abstract: 2084185 9118682 PCTABS00008 A process and apparatus for directing coating materials at a substrate with reduced production of mist and enhanced range of coating thickness and uniformity of coverage. A flow of coating liquid or fluid (821) is directed toward a substrate, and attenuated (826) in transit by a co-flowing impingement fluid (823). The impingement fluid is capable of attenuating liquid in the coating stream into droplets that form a fine mist (827). The mist is propelled toward the substrate (826) by the impingement fluid and deposited on the substrate. The aqueous liquid is preferably less than 100 ·C, and directed through an outlet under a low pressure, for example, less than 12 psi (82 kPa, such that the liquid velocity is low (e.g. less than 1 meter/second). Process parameters may be varied to reduce grainy or streaky coatings, thereby assuring thorough coverage of a substrate even with very thin coatings.
