Abstract: PURPOSE:To enable a main body part and a cap part which are formed by splitting the large end part of the connecting rod into two to be reassembled easily with a high reassembling accuracy by arranging three or more split assisisting holes in zigzag manner in left and right split parts of the large end part of the connecting rod. CONSTITUTION:The connecting rod 11 provided at its large end part with a bearing hole 13, a bolt hole and split assisting holes 16, 17 and 18 is subjected to cementation hardening. Then, a pair of split collars 19A and 19B are inserted into both sides with respect to a split line within the bearing hole. A wedge 20 is driven into a space formed between both split collars 19A and 19B whereby the large end part 12 is split into the main body part 12A and the cap part 12B. Upon this occasion, rupture surfaces 21 produced on left and right split parts of the large end part are guided by split assisting holes 16, 17 and 18 mutually arranged in zigzag shape, and formed in a substantial V shape. Upon reassembling, both the main body part A and the cap part B are automatically aligned by clear depressed and projected parts formed on the rupture surfaces.

Title: Spread signal demodulation method by quaternary moment method
Inventor: MATSUNO TATSUJI
IPC: H04B1/707
Filed: 1991-05-09
Abstract: PURPOSE:To demodulate a data accurately by obtaining a correlation between a spread spectrum signal and plural PN series and comparing the quantities of a quaternary moment around square mean values of the correlation. CONSTITUTION:A modulator M outputs a spread spectrum signal modulated to output a PN 0 series when the state value of the information whose transmission speed is 1/To is 0 and output a PN1 series of the same period length as that of a PN0 series when the state value of the information whose transmission speed is 1/To is 1. Correlation devices 14,15 of a demodulator D obtain simultaneously the correlation of the spread signal and the PN0 and PN1 series. Outputs of the correlation devices 14, 15 are added by an adder 20 through PN series generators 16,17 and square circuits 18,19 generating the same PN0, PN1 series as those on the modulator side. From the output, quaternary moment arithmetic operation circuits 22,23 calculate a quaternary moment and a comparator 25 compares the quantities. Then in which PN series a peak of the correlation value exists is estimated to demodulate the data.
