Title: Teleconference microphone arrays
Inventor: WALLACE JR ROBERT LEE
IPC: H04R3/00
Filed: 1980-12-17
Granted: 1985-05-07
Abstract: In the directional array of acoustic transducers, the acoustic transducers are arranged colinearly and in pairs symmetrically about a center line of the directional array. The distances of the acoustic transducers on either side of the center line of the array are neither linear nor monotonic.

Title: Data processing system
Inventor: YANAKITA TOMOASSU
IPC: G06F7/50
Filed: 1981-07-14
Granted: 1986-06-25
Abstract: A number of bytes are processed at a same time by an arithmetic operating unit. A second operand is aligned to a position of the first operand and the aligned second operand is supplied to the operating unit while the first operand is supplied to the operating unit. Since the second operand is aligned to the position of the first operand before it is processed in the operating unit, the processing time is shortened. Zero assurance circuits assure zeros in the ineffective positions of the first and second operands.

Abstract: The bottom-most page is fed first from a face-up stack of sheets and the copied sheets restacked face-up, with the bottom sheet at the bottom of the new stack. It operates in excess of 25 copies per minute. Drive wheels feed the document-to-be-copied onto the copier glass and, when the wheels are reversed, remove the document from the glass into a stacking area. The removal of a document from the glass and the placement of the next document onto the glass and the placement of the next document onto the glass occur during the non- copying time of the continuouslyrunning documents. The copier can derive its driving force and energy from the copier or can have its own independent power source.

Abstract: A method of and apparatus for recording a first and a second EFM-modulated signal is described, which signals comprise EFM-subcode frames, the beginning of each EFM-subcode frame being marked by a subcode-synchronisation signal. In the track portion of a record carrier (1) intended for recording position-synchronisation signals are recorded by means of a track modulation which can be distinguished from the information pattern to be formed. During recording the subcode-synchronisation signals are maintained substantially in phase with the position-synchronisation signals (11), so that the track portions (14) in which the subcode-synchronisation signals are recorded substantially coincide with the track portions (140) in which the position-synchronisation signals are recorded. Recording of the first EFM-modulated signal (142) ends at a boundary position (144) which is situated at a predetermined position between the track portions (140) in which two successive position-synchronisation signals are recorded. Recording of the second EFM-modulated signal (143) begins substantially at the predetermined boundary position (144).
