Abstract: Drum or smooth side-treated metal foil can be used either as an intermediate product for use in the manufacture of laminate or as a part of the finished laminate to be used in the manufacture of multi-layer printed circuit board (PCB) packages. By treating the drum or smooth side (11) of metal foil (10) with a bond strength enhancer (13) rather than treating the matte side or rough side (12), or both sides, several time-consuming and costly steps can be bypassed in the manufacture of multi-layer printed circuit boards (PCB) while the integrity of the metal foil, laminate and multi-layer PCB are not compromised and are actually enhanced by way of improved impedance control and adhesion characteristics after relamination. This novel foil can be initially bonded to substrate on either side before circuit formation and can be used either as an internal foil layer or as a foil cap. The invention includes methods of manufacture of the metal foil, laminate and multi-layer printed circuit board. A variation of the invention involves a component or tool for use in manufacturing articles such as printed circuit boards. The component is a temporary laminate constructed of one or more sheets of drum-side-treated copper foil mounted on a sheet of aluminium. The copper foil, which, in a finished printed circuit board, will constitute a functional element, has a drum-side, which has been subjected to an adhesion-promoting treatment, and a rough side, which has not been subjected to the adhesion-promoting treatment. The sheet of aluminium constitutes a discardable or reusable element. Either surface (treated drum-side or untreated matte side) of each copper sheet can be bonded to the aluminium, depending on which embodiment of the basic invention is being used. The side of the copper foil not bonded to the aluminium will be bonded to the resin in the next step.

Title: Sound generator synchronized with image display
Inventor: SHIMIZU HIDEAKI
IPC: G06F3/16
Filed: 1996-09-19
Granted: 2006-04-25
Abstract: Digital sound source data is stored in a sound source data memory 22. When a first display object (an enemy character, a waterfall, or the like) so defined as to generate a sound is displayed in a three-dimensional manner on a display screen 41 of a television 40, a audio processing unit 12 reads out the corresponding sound source data from the sound source data memory 22, to produce first and second sound source data. The first and second sound source data are converted into analog audio signals by digital-to-analog converters 16a and 16b, and are then fed to left and right speakers 42L and 42R. At this time, the audio processing unit 12 calculates delay tame on the basis of a direction to the first display object as viewed from a virtual camera (or a hero character), and changes delay time of the second sound source data from the first sound source data. Further, the audio processing unit 12 individually controls the sound volume levels of the first and second sound source data depending on the distance between the first display object and the virtual camera (or the hero character).   Consequently, sounds having a spatial extent corresponding to the change of a three-dimensional image can be respectively generated from the left and right speakers 42L and 42R.

Title: Split beam optical character reader
Inventor: ROSS WILLIAM
IPC: G06V10/147
Filed: 1997-05-07
Granted: 2007-08-21
Abstract: An optical system for an optical character reader in which a camera, such as a TV camera, reads an image field in a document, includes at least one pair of mirrors which shift half of the image both laterally and vertically to convert a relatively long image, for example with a length to height aspect ratio of 1.5:8, into a rectangular image with a much lower aspect ratio, for example 3:4. Preferably two pairs of mirrors are used, so that the image light path for both parts of the image field is the same length. This optical system reshapes the image field from one having an aspect ratio which does not match the 3:4 aspect ratio of most cameras, such as camcorders, TV cameras, security and surveillance cameras and the like, into one that does, thus significantly simplifying the optical character reader, and lowering its cost.
