Title: Rounding processing system in binary floating point multiplication
Inventor: YOSHIDA YUJI
IPC: G06F7/52
Filed: 1987-12-26
Abstract: PURPOSE:To decrease the number of processing steps and to execute the high speed of a processing by early detecting the generation of a mantissa overflow in a rounding processing and executing the rounding processing of the mantissa before regularizing processing. CONSTITUTION:The rounding processing when a mantissa overflow OVF 1 occurs and the rounding processing when it does not occur are prepared beforehand, and switching is executed to either of them by the presence and absence of the mantissa overflow OVF 1 generation. Namely, the rounding processing is executed by a rounding processing determining circuit 13 and a rounding adder 14 beforehand for the intermediate result before the regularizing processing, and a mantissa post-operation regularizing circuit 15 executes the regularizing processing including a mantissa overflow OVF 2 to occur by the rounding processing. Thus, the number of the processing steps is decreased and the high speed of the processing is executed.

IPC: H04L47/22
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a simplified transmission band control circuit for ATM (asynchronous transfer mode) communication where transmission of multiple channel cell is controlled. SOLUTION: A cell transmission-enable times ST of a group of a control object channel stored in a control memory 14 is sequentially read for a time TM outputted from a time counter according to a cell synchronizing signal SY and a difference DF from the time TM is calculated. A transmission discrimination section 17 outputs a transmission-enable channel number AC. A pre- discrimination section 18 stores a channel number that reaches a transmission time within a prescribed time. The stored channel numbers are sequentially shifted by the cell synchronizing signal SY and the result is outputted as a transmission-enable channel number AC from the pre-discrimination section 18 when the transmission time comes.  The transmission-enable channel number AC is processed sequentially by a contention discrimination section 19 and the result is given to a memory control section 12 as a transmission channel number SC and a corresponding cell is read from a cell storage memory 13 and transmitted.

Title: Original reader
Inventor: TOKUMASU TAKAHIKO
IPC: H04N1/04
Filed: 1993-12-01
Abstract: PURPOSE:To record an inclined picture with correction without causing the deterioration in the oblique sensing accuracy by providing a low reflection area in the vicinity of both ends in the broadwise direction of a reflection component and detecting the inclination based on a reflected light from both ends of a top edge of the original. CONSTITUTION:Before an original front edge reaches a read section 6, the light from a read light source 10 strikes on a reflection component 5 and the light reaches a CCD 13 via a mirror and a lens. In this case, a light striking on a low reflection area of the component 5 is not almost reflected. That is, a circuit discriminating whether a picture element signal subject to photoelectric conversion by the CCD 13 is a white level signal or a black level signal discriminates the signal to be a black level signal. When the tip ridge of the original reaches the low reflection area and shuts it, a potential of a relevant picture element forming an image on the CCD 13 gets higher than a threshold level and a white level is discriminated. When the original is inclined in this case, the timing for discrimination of a white level differs from left and right edges. A tilt angle of the original is obtained from a timing difference and read picture data stored in the memory are rotated based on the obtained tilt angle to obtain picture data without a tilt.

Abstract: PURPOSE:To prevent abnormal noise of a polyurethane foam cushion, by a method wherein at least either mold release agent or silicone is applied to at least a part of the rear of the cushion, against which a steel material such as a spring, frame and pipe abut after molding of a polyurethane foam. CONSTITUTION:A polyurethane foam stock solution is foamed by casting the same into a molding mold and a polyurethane foam 1 having a protrusion 1a on a surface side is obtained.
