Title: Solar cell and method of making same
Inventor: WALD FRITZ
IPC: H01L31/0224
Filed: 1992-05-08
Abstract: An improved solar cell of the type including a semiconductor substrate (2) having a shallow p-n junction (3) adjacent its front surface (4), a rear electrode (6) affixed in adherent mechanical and electrical contact with the rear surface (7) of the semiconductor substrate (2), and a front generally grid-shaped electrode including an array of narrow, elongate, parallel fingers (10) and at least one bus bar (13) extending at right angles to the fingers in electrical contact therewith affixed in mechanically adherent and low resistance electrical contact with the front surface (4) of the semiconductor substrate (2). The improvement includes the removal of the bus bar portion (13) of the front grid-shaped electrode from intimate mechanical and electrical contact with the front surface (4) of the semiconductor substrate. The improvement increases the open circuit voltage and efficiency of the solar cell, and allows the bus bar portion (13) of the grid shaped electrode to be formed of materials different from the finger portions (10) of that electrode thereby providing cost advantages and design flexibility without detriment to solar cell efficiency. A  method of making the improved solar cell also is disclosed.

Title: Sternum Banding Assembly
Inventor: BLASNIK WILLIAM
IPC: B25B25/00
Filed: 1993-01-26
Abstract: A banding assembly has a needle at one end, a long thin band, and a buckle at the other end. The buckle is provided with upstanding elements on either side of a channel which receives the band.  The elements have openings adapted to be engaged by a towel clamp to retain the buckle as the band is drawn through the channel and locks into position.  The elements are normally spaced apart by a distance slightly less than the width of the band. Once locked into place, the band is trimmed, leaving a tail extending from the buckle. The tail is bent backwards and "snap fits" between the elements. The elements are then crimped over the tail to retain it on the buckle and to cover any sharp edges. A dome-like member is provided to guide the band into the channel. The buckle is attached to the end of the band by spaced tabs which extend through openings in the band and are crimped toward each other.

Inventor: BROWNE JOHN
IPC: G02B26/02
Filed: 1993-02-22
Abstract: A shutter is designed for use with an optic fibre which is designed to emit rays in a cone in a selected viewing direction. A mount carries the optic fibre to emit such cone.      Associated with the mount is means for rotatably mounting the shutter, or rotor to rotate between ON and OFF positions. The shutter is shaped to provide a panel which blocks the cone in the viewing direction in the OFF position. The shutter is shaped to define, in ON position a central opening for passage of the cone of light in the viewing direction. Rotation between ON and OFF position is about 90°. An Electromagnetic drive is used to drive the shutter between ON and OFF positions.      The fibre is centrally located relative to the fibre mount. A plurality of shutters, each with its own drive may be arranged in line, in a single strip module.

Patent CA-2093118-A1 (CA)
Title: Shoe including an exchangeable heel
Inventor: OHSAWA TSUGUYOSHI
IPC: A43B21/37
Filed: 1992-08-07
Abstract: ABSTRACT The present invention relates to the structure of shoe's heel, and more particularly, to a shoe which assures that a lift of the shoe can easily and simply be exchanged with a new one.  Hook-shaped engagement projections 6 are caused to stand upright on the upper surface of the lift, while an engagement plate 8 is secured to the lower end surface of a heel. Engagement holes 13 are formed on the engagement plate 8 so as to allow the hook-shaped engagement projections 6 to be engaged with the engagement holes 13 by displacement of the lift relative to the heel.  When the hook-shaped engagement projections 6 are engaged with the engagement plate 8, the lift and the heel are firmly assembled together while preventing the lift from being disconnected from the heel in the vertical direction.  A locking pin 11 adapted to be normally biased in the direction of approaching toward the lift is received in a pin hole which extends through the heel and the lift in the vertical direction.  Once the lift is secured to the heel, the locking pin 11 prevents the lift from being displaced relative to the heel in the horizontal direction.

Title: Two-phase method for real time process control
Inventor: BONAQUIST DANTE P
IPC: G05B17/02
Filed: 1993-06-15
Abstract: TWO-PHASE METHOD FOR REAL TIME PROCESS CONTROL                 Abstract of the Invention A method of process control using linear programming models to implement the control of one or more controlled variables to maintain a desired target value over a given time horizon.  The controlled variables are controlled by a process controller which adjusts manipulated variables in real time.  The method uses two linear programming models with the second model computed from the solution of the first in which the absolute value of the deviation for each controlled variable from its target value over a specified time horizon is computed.  This permits the controlled variables to be adjusted with the changes in the manipulated variables held to a minimum over the time horizon under control.

IPC: G10L15/22
Filed: 1994-03-08
Abstract: A transcription interface (10), connected to a general purpose digital computer ( 11 ) and a digital dictation recorder (20), for controlling various transcription functions and for automatically transferring information concerning dictation from the recorder (20) to an application program running on the digital computer (11). The recorder (20) generates a sequence of digitized dictation signals including a dictation segment and a digitized identification signal containing information corresponding to the dictation segment. The transcription interface (10) supplies an audio signal to an audio port (43) by converting the digital dictation signal to a signal that audibly reproduces the dictation for transcribing by a transcriptionist. The transcription interface (10) also formats the digitized identification signal to generate a message signal having a signal format compatible with the interface (10). In response to an interrupt signal generated by a timer interrupt circuit (17) of the computer (11), the transcription interface (10) automatically sends the message signal to an application program running on the computer (11) for display by a video display (14) connected to the computer (11). In response to an interrupt signal generated by the application program, the transcription interface (10) supplies a status signal containing information concerning the operation of the application program to the recorder (20). The operation of certain keys on a keyboard (13) connected to the computer (11) generates keyboard interrupts that initiate various transcription control functions by the transcription interface (10).
