Patent CA-1297664-C (CA)
Inventor: NISHIGUCHI MASANORI
IPC: H01L21/68
Filed: 1988-08-29
Granted: 1992-03-24
Abstract: Abstract In a chip mounting apparatus, a plurality of chips individually bonded on an adhesive tape are removed from the tape and mounted in a package or on a printed circuit board.  The apparatus has a vacuum pickup member movable for picking up each chip by vacuum.  At least one push rod is movable for pushing up the chip from a lower surface of the tape towards the pickup member.  A tape driving portion draws the tape downwards from a peripheral portion of the chip, and a sensor detects when the tape has been separated from the peripheral portion of the chip.  The push rod or rods are withdrawn by a signal from the sensor.  The sensor can be optical or can take the from of a load detecting monitor for detecting the load exerting upon the push rod or rods, or the tension in the tape.  The apparatus has the advantage that, once separation has taken place, the apparatus can proceed to the next step without delay.

Title: Laser initiated ordnance system optical fiber continuity test
Inventor: JACOBS RICHARD
IPC: F42B3/113
Filed: 1988-09-01
Granted: 2003-02-18
Abstract: An apparatus is disclosed for testing the integrity of an optical fiber (23) from a single end of the fiber. A test light source (34) with a wavelength that is different from the primary light source (14) is directed into one end of the optical fiber (23). A spectrally selective dichroic material (32) is attached to the other end of the optical fiber (23).      This material (32) transmits light of the wavelength of the primary light source (14) and reflects light of the wavelength of the test light source (34). A break or discontinuity in the optical fiber (23) can be detected by an attenuation in a pulse of light from the test light source (34) after it is transmitted though the optical fiber (23) and reflected back out of the optical fiber (23) by the dichroic material (32). This system can detect breaks or discontinuities in the optical fiber (23) with a high degree of resolution.

Title: Drum clamping unit for "l" ring drum
Inventor: BERG BRUCE A
IPC: B66F9/06
Filed: 1988-12-02
Granted: 1991-10-08
Abstract: ABSTRACT      A drum clamping unit for plastics material drums with peripheral "L" chime rings below the drum heads is adapted to be mounted on suitable lifting and transporting devices such as lift trucks, overhead cranes, and the like to automatically engage, latch onto, and discharge one or more of the molded plastics material drums without damaging the drums.  The unit has a plurality of clamping jaws automatically triggered to clamping positions by the drum heads as the unit is lowered alongside the drums.  These clamping jaws are positioned to engage only with the bottom and inner face of the "L" chime ring of each drum and remain clear of the drum head and drum periphery thereby avoiding any damage to the drums especially as they are raised to clamp onto the "L" rings.  Then, when the raised clamped drums are conveyed to and lowered on a desired location, the jaws are released, retracted automatically and held in a retracted position until the unit is again lowered to engage a drum head in a subsequent operation.  A preferred unit handles up to four upright drums positioned in a ring cluster or nest.

Title: Low voltage programmable compressor
Inventor: WALDHAUER FRED D
IPC: H04R25/00

Granted: 1991-12-10
Abstract: IMPROVED LOW VOLTAGE PROGRAMMABLE COMPRESSOR         ABSTRACT OF THE DISCLOSURE A programmable low voltage compressor circuit suitable for use with hearing aids is described.  The compressor has a continuously variable compression ratio wherein the gain of the compressor may be programmably controlled over a wide range and the compressor may be powered from a power source as low as 1.1 volt.  The compressor employs a variolosser wherein the gain is controlled by the ratio of the currents flowing out of first and second control terminals.  A control circuit coupled to the variolosser controls the magnitude of the currents flowing out of the two control terminals.  The control circuit includes a peak detector which generates a signal related to the peak positive envelope of the signal input to the compressor.  A voltage to current converter is coupled to the peak detector for increasing the magnitude of the current flowing out of one of the control terminals of the variolosser as the voltage output of the peak detector increases.  Furthermore, the gain and compression ratio of the compressor over a wide range is programmably controllable.

Title: Technique for reading bar code
Inventor: SARNA DAVID E Y
IPC: G06K7/10
Filed: 1989-05-29
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE      A technique for reading a bar code representative of message information is stored electronically in bit-map form.          The bit map is obtained by optically scanning a document carrying non-bar code information also to convert pixel information into bit information.  A row is identified in the bit map which is the most likely one to pass through an area in the bit map containing bar code information.  The data stored in the bit map is compared with assigned data corresponding to designated bar code components.  Once such a row is identified, processing of rows above and below it in the bit-map reveals whether rows more likely to agree with the coded message information can be found.  Initially, a fast processing mode is selected involving processing of only a few rows to maximize processing speed in case acceptable data can be found.  If acceptable bar code data is not found, then the processing is switched into a slow processing mode which involves processing of a greater number of rows.  Once a row likely to contain the bar code data of interest is identified, the information it contains is converted into signals which are used for converting the coded bar code data into the message represented thereby.

IPC: B62D5/06

Granted: 1990-01-29
Abstract: An open center hydraulic system is disclosed which contains a primary work circuit and a secondary work circuit. A fixed displacement pump is fluidly connected between a reservoir and the primary and secondary work circuits for supplying pressurized fluid thereto. The primary work circuit includes a control valve which regulates fluid flow from the pump to a primary hydraulic function and which includes a feedback mechanism connected thereto. The secondary work circuit also includes a manually operable control valve for regulating fluid flow from the pump to a secondary hydraulic function. A priority valve is connected between the pump and the secondary work circuit and is movable between an open and a closed position to regulate the pressure of fluid discharged by the pump. Pressurized fluid from the primary work circuit is conveyed through a load signal line to the priority valve such that the pressurized fluid will urge the priority valve towards the closed position thereby assuring that adequate fluid pressure is available from the pump to the primary work circuit. The system also includes a control valve for sensing pressure variations between the fluid discharged from the pump and fluid present in the load signal line. This valve controls fluid flow out of the primary hydraulic function, via the load signal line, when the pressure of the fluid discharged by the pump is less than the pressure of the fluid in the load signal line and thereby essentially eliminates kickback from the primary control valve.
