Title: Reduced noise multi-ribbed power transmission belt
Inventor: WILSON JAMES JOHN
IPC: F16G5/20
Filed: 2002-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a reduced noise power transmission belt with a tooth-like multi-line of rib capable of reducing the harmonic spike noise similarly with the noise over the whole. SOLUTION: This multi-ribbed power transmission belt has several lateral grooves directed at an angle except for a right angle in a compression range. Multiple teeth are formed on a belt surface by combining longitudinal grooves and lateral grooves, and a tooth line is defined between adjacent lateral grooves. Each tooth has a pitch length P between a certain position on the tooth and the same position of the adjacent tooth formed in the longitudinal direction. In order to reduce the noise of the belt when the belt travels around a pulley combined with the belt, the pitch length of the tooth line is arranged at random over the whole length of the belt.

Title: Method and system for manufacturing spectacle lens
Inventor: UENO YASUNORI
IPC: G02C13/00
Filed: 2002-06-24
Abstract: <P>PROBLEM TO BE SOLVED: To enable a user to obtain a satisfactory binocular vision regardless of a large eyesight difference by reducing the difference in chromatic aberration of magnification between right and left lenses.  <P>SOLUTION: When right and left spectacle lenses are designed and manufactured which constitute spectacles to which different prescriptions including degrees are given for right and left eyes, standard design data of lenses for right and left lenses are generated on the basis of information of the prescriptions including degrees (step S3). Next, it it discriminated whether the difference in chromatic aberration of magnification between lenses for right and left eyes, based on standard design data is a smaller than a prescribed value or not (step S4). When the difference in chromatic aberration of magnification is not smaller than the prescribed value, a re-design data obtained by changing lens materials or the like so as to make the difference in chromatic aberration of magnification between lenses for right and left eyes smaller than the prescribed value is generated (step S5). Lenses for right and left eyes are processed on the basis of re-design data when re-design data is generated, and they are processed on the basis of standard design data when re-design data is not generated (step S7), and thus chromatic aberration balance between right and left lenses is kept within a proper range.  <P>COPYRIGHT: (C)2004,JPO

IPC: B41J2/36
Filed: 2002-06-25
Abstract: <P>PROBLEM TO BE SOLVED: To facilitate correction of a heat history operational expression of a thermal head of a thermal printer when the type of the thermal head is changed, or when the thermal printer is required to carry out high-speed printing or printing with improved printing quality.  <P>SOLUTION: In the thermal printer, a software program 21 in which the thermal history operational expression is installed is incorporated in a software storage medium 20. A CPU 10 receives printing data via an interface section 70, and reads the software program 21 from the software storage medium 20, followed by executing a heat history operation for the printing data, to thereby create heat history data. Alternatively, the CPU 10 may first develop the software program 21 in a main storage medium 30 and read the same from the main storage medium 30, followed by executing the heat history operation. Then, the CPU 10 sends out the created heat history data to a data transfer circuit 42 which further transfers the received heat history data to the thermal head 50. In the thermal head 50, a heater is selectively driven according to the transferred heat history data, and therefore desired printing is carried out on recording paper.  <P>COPYRIGHT: (C)2004,JPO

Title: Convolutional decoder
Inventor: MUJTABA SYED AON
IPC: H03M13/41
Filed: 2002-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a decoder which can be packaged with high area efficiency and little complexity at a low cost by various application including an application to utilize the code of a great restrict length in a wireless base station receiver or the like. SOLUTION: This decoder has a branch metric calculator 88, an ACS engine 90 and a traceback unit 92. The branch metric calculator 88 computes branch metrics for transitions in a trellis representative of a convolutional code used to generate the symbols. The branch metrics are computed from an offset binary representation of the symbols using an inverse likelihood function, such that a strong match between a given received symbol and a possible codeword of the convolutional code results in a small branch metric, while a weaker match between a given received symbol and a possible codeword results in a larger branch metric. The corresponding path metrics therefore grow at a smaller rate.
