Patent CA-2461274-C (CA)
Title: Photoelectric current multiplier using molecular crystal and production method therefor
Inventor: HIRAMOTO MASAHIRO
IPC: H01L51/00
Filed: 2002-07-31
Granted: 2012-10-02
Abstract: A NTCDA single crystal is used as a photoelectric current multiplier layer, and Au thin films are formed as electrodes on the opoosite surfaces of the multiplier layer by a vapor deposition method to form a sandwich type cell. When a voltage is applied to the NTCDA single crystal by the electrodes from a dc power source and a monochromatic light is applied, a multiplied photoelectric current flows between the electrodes. A rise of this element at light-on is considerably faster than when a vapor-deposited layer is used as a photoelectric current multiplier layer to permit a faster response.

Abstract: The present invention is a toneable conduit that can transmit a signal and that can therefore be readily detected by toning equipment. In addition, the conduit of the invention can be readily coupled with other conduit to provide extended lengths of conduit. The toneable conduit includes an elongate polymeric tube having a wall with an interior surface, an exterior surface, and a predetermined wall thickness. A channel preferably extends longitudinally within the wall of the elongate polymeric tube and a stabilizing rib (20) extends longitudinally along the interior surface of the wall of the elongate polymeric tube and is located radially inward from the channel. A continuous wire (24) is coincident with the channel in the elongate polymeric tube and is preferably coated with a coating composition that prevents the wire from adhering to the polymer melt used to form the elongate polymeric tube. The present invention further includes methods of making the toneable conduit and methods of coupling a first toneable conduit with a second toneable conduit.

Abstract: Methods, systems, and computer program products for adding hinting instructions to a character in order to improve a character bitmap produced from an outline of the character at a certain size and output resolution when the character outline is scan converted. A character is retrieved to be output. A determination is made that the character belongs to a semantic character classifications, and hinting instructions that are associated with the semantic character classification are accessed. The hinting instructions preserve semantic meaning for the character while altering either stroke presence, stroke location, or both for at least one stroke of at least one feature of the character based on a reference character size and output resolution. If the actual character size and output resolution for the character is within a reference character size and output resolution for the hinting instructions, the hinting instructions are executed.

Patent CA-2533498-C (CA)
Inventor: CHRISTIAN KEVIN
IPC: H03F3/217
Filed: 2004-07-26
Granted: 2013-08-27
Abstract: The invention is a power amplifier circuit for providing a signal acceptable for use in audio amplifiers or similar applications without requiring a stable power supply free from fluctuation. An alternating current power supply signal rectified to a direct current signal is processed by two voltage multipliers (20, 23). A voltage divider (15) establishes a unity gain level, and the variance from this voltage is squared by the first voltage multiplier. This squared voltage is then multiplied with a triangular wave signal to generate a modulated triangular wave signal. The modulated triangular wave signal and a signal to be amplified, typically an audio signal, are processed by an internal comparator (25) to generate a pulse width modulated signal. This modulated signal is processed by a power transistor network (30) and filter (40) to provide an amplified signal to a load device (45). By modulating the triangle wave signal to compensate for fluctuations in the power supply to the amplifier circuit, noise or ripples present in the power supply are demodulated, eliminating the requirement for a regulated power supply.
