Patent CA-2092343-A1 (CA)
Inventor: UCHIDA HIROMICHI
IPC: G11B33/04
Filed: 1993-03-24
Abstract: A floppy disk container comprises a plate having an adhesive tape or agent applied to a rear face thereof.  Three edges of a flexible plastic film of an approximately square shape are fastened to the plate, and the remaining edge of the film is free from attachment to the plate and positioned at a mid portion of the plate in order to obtain an upwardly opening insertion opening of the floppy disk container.  Thus, a bag-shaped floppy disk container is obtained.  A pair of stoppers are formed to protrude from an upper portion of the front face of the plate at positions just above the top edge of the floppy disk when the floppy disk is in the container, so as to abut the top edge of the floppy disk and prevent the floppy disk from falling out of the container.   In addition, a transverse elongated ridge in parallel with the insertion opening is formed on the front face of the plate between the insertion opening and the stoppers,  in order to leave a gap between the top edge of the floppy disk and the plate.

Title: Core element for catalytic converter
Inventor: SHELLER DAVID T
IPC: B01J23/86
Filed: 1993-05-11
Abstract: ABSTRACT OF THE DISCLOSURE             There is provided a novel and improved core element for a catalytic converter characterized in that the core element has a corrugated thin metal strip with bent tab members at each end, such tab members being in two portions.          These two portion sandwich the ends of the corrugated thin metal strip therebetween and provide a convenient means for welding the ends of the corrugated thin metal strip to the tab members. A plurality of such corrugated strips with the tab members attached are tightly spirally wound about a central post or pin and the tab members are dimensioned to overlap and ultimately define a shell segment. The shell segments define a core which is encased in a suitable housing to form a catalytic converter which may be electrically heatable.  An electrically heatable catalytic converter is especially useful to remove pollutants from internal combustion engine exhaust gas.

Inventor: OGAWA KEN
IPC: F02D41/14
Filed: 1993-05-17
Abstract: An air-fuel ratio control system for an internal combustion engine includes a LAF sensor and an O2 sensor arranged in an exhaust pipe at respective locations upstream and downstream of a catalytic converter.  A desired air-fuel ratio coefficient used in calculating an amount of fuel supplied to the engine is calculated based on operating conditions of the engine, and corrected based on output from the O2 sensor.  The air-fuel ratio of a mixture supplied to the engine is feedback-controlled to a stoichiometric air-fuel ratio based on the corrected desired air-fuel ratio coefficient.  When the output from the O2 sensor falls within a predetermined range, the desired air-fuel ratio coefficient is not corrected, but held at an immediately preceding value thereof.

Title: Fluid pump with magnetically levitated impeller
Inventor: KLETSCHKA HAROLD D
IPC: A61M60/183
Filed: 1992-10-06
Abstract: A fluid pump (10) with rotary impeller (68) is disclosed which comprises an electromagnetically-driven (30), bearing five, seal-free rotary impeller (68) levitated by localized opposed, repulsive, permanent magnetic forces (60, 64) only. Levitation by lo-calized opposed magnetic or magnetic and fluid forces (52) of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping me-chanisms which can be of importance in pumping of physiological fluids such as blood. The levitating forces of the present in-vention are applied repulsively both axially and radially with respect to the impeller and are auto-adjusting, such that any at-tempted displacement of the impeller will automatically incur a corrective change in levitating forces. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.

Patent CA-2121294-A1 (CA)
Inventor: HERGET GERHARD H
IPC: G01L5/00
Filed: 1994-04-14
Abstract: The invention relates to the field of measuring instruments and, in particular to sensing apparatus capable of measuring displacement or deformation for the ultimate purpose of monitoring strain and/or stress. The vibrating wire measuring principle provides a very reliable method of measuring small deformations with high precision. Measurement apparatus utilizing this principle, however, tend to be limited in range to the elastic limit of the stretched wire. To increase the useful range of measurement of a vibrating wire monitor, a spring may be placed in series with the wire. In order to prevent the spring from vibrating during the resonancing  of the wire and thereby delaying the determination of the wire's resonant frequency, the invention contemplates isolation of the spring from the wire in a vibrational sense. In one form of the invention, isolation is achieved by causing a nodal point to be formed on the spring side of the wire. The nodal point may be formed by pressing a fret against the wire.
