Patent CA-2120099-C (CA)
Inventor: ISE KOICHI
IPC: G02B15/16
Filed: 1994-03-28
Granted: 2004-08-17
Abstract: An image pickup optical system having an image pickup lens system having in turn a plurality of lenses arranged in multiple stages for forming an image of an object on an image plane of an image pickup device is disclosed. The image pickup optical system includes a double refraction plate arranged downstream of the image pickup lens system, a diaphragm unit, as a first optical unit, for determining the F-number of the image pickup lens system by a diaphragm aperture, and a second optical unit.      When the F-number is equal to a pre-set value Fd or less, the second optical unit operates in conjunction with the double refraction plate for lowering the modulation transfer function (MTF) by the aberration due to an aspherical surface for a range of the spatial frequency not less than the cut-off frequency r c.      Sufficient spurious signal suppressive effects may be obtained even if the optical low-pass filter is constituted by a sole double refraction plate, such as a quartz plate.

IPC: B01J38/38
Filed: 1991-10-30
Granted: 2001-01-02
Abstract: In a process for controlled, multi-stage regeneration of FCC catalyst, a modified high efficiency catalyst regenerator (80), with a fast fluidized bed coke combustor (62), dilute phase transport riser (83), and second fluidized bed (82) regenerates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor (62), whereas a second stage catalyst regeneration occurs in the second fluidized bed (82). The amount of combustion air added to, and conditions in, the coke combustor (62) are controlled to limit CO combustion, while the second stage of regeneration, in the second fluidized bed (82), achieves complete CO combustion. Controlled multi-stage regeneration reduces steaming or deactivation of a catalyst during regeneration, increase coke burning capacity, and reduces NOx emissions.

Title: Apparatus and method for mounting an electrical box between studs in a wall
Inventor: OLIVA JOHN H
IPC: H02B1/015
Filed: 1994-01-04
Granted: 2005-03-29
Abstract: An improved apparatus and method for mounting an electrical box between sands in a wall is disclosed. The apparatus of the invention is a mounting bracket comprising a relatively flat, elongated frame having a front planar face, a rear planar face, and a first and second opposing ends attachable to two corresponding wall studs. The frame also has a central cut-out portion which defines a top edge and a bottom edge. An electrical box and its accompanying faceplate may be mounted between two wall studs by first attaching the bracket of the present invention to the wall studs. The open front end of the box is then placed flush against the rear face of the bracket such that a top portion of the box contacts the top edge of the bracket and a bottom portion of the box contacts the bottom edge of the bracket. Similarly, the accompanying faceplate is placed on the front face of the bracket opposite and aligned with the box such that a top portion of the faceplate contacts the top edge and a bottom portion of the faceplate contacts the bottom edge. The mounting is completed by fastening the box and the faceplate to the bracket. Mounted in this manner, the front end of the box will be substantially flush with the plane formed by the wall studs regardless of the depth of the box.

Abstract: A method of transferring update data from a microcomputer to a memory device having a transportable non-volatile memory medium requiring that the transportable non-volatile memory medium is divided into a plurality of sectors.  Update data is to be written to data sectors of the transportable non-volatile memory medium in accordance with a sector map. One of the sectors to be updated is the directory sector and another one of the sectors to be updated is the file access table sector.  The microcomputer is programmed to reserve a specified number of sectors as a recovery area wherein some of the sectors of the recovery area are reserved for the sector map and other sectors of the recovery area are reserved for storage of the update data.  The microcomputer identifies if a sector map resides in the recovery area.  If no sector map resides in the sector map area of the recovery area, the microcomputer proceeds to identify which of the sectors are to be updated and generating a sector map accordingly.  If a sector map resides in the recovery area, the microcomputer first writes data from the recovery area to the sectors according to the sector map and then proceeds to identify which of the sectors are to be updated and generating a sector map of the sectors to be updated.  The microcomputer then writes the sector map and the update data to the recovery area before writing the update data to the sectors in accordance with the sector map.  Once the respective sectors are updated the sector map is erased.

Abstract: RNA is transcribed from a double stranded DNA template by forming a complex by hybridising to the template at a desired transcription initiation site one or more oligonucleic acid analogues of the PNA type capable of forming a transcription initiation site with the DNA and exposing the complex to the action of a DNA dependant RNA polymerase in the presence of nucleoside triphosphates. Equal length transcripts may be obtained by placing a block to transcription downstream from the initiation site or by cutting the template at such a selected location The initiation site is formed by displacement of one strand of the DNA locally by the PNA hybridisation.

Abstract: A drive type operating mechanism for locking gates, windows, double-wing doors and the like includes push rods which are movable longitudinally in opposite directions to effect locking of the upper and lower ends of the door with the surrounding framework.  The mechanism is connected for actuation by a lever handle through an arrangement of follower elements that are slidable supported in a lock case.  A nut sleeve follower which is rotatable by the lever handle has one claw which cooperates with a groove in one longitudinally movable follower, and a second claw which cooperates with a transversely slidable intermediate follower which in turn cooperates with a groove in the second longitudinal follower, this arrangement ensuring that upon rotation of the handle the followers (and hence the locking bolts) move in opposite directions.  A lock mechanism ensures that the longitudinally movable followers are not inadvertently moved from their end limiting positions.
