Title: Modulating method of spread spectrum communication
Inventor: TAKEMOTO KATSUMI
IPC: H04B1/7073
Filed: 1983-03-08
Abstract: PURPOSE:To prevent code errors of an information signal by selecting the type of a pseudo noise code in response to the state of the information signal to eliminate the need for a narrow band filter at the receiving side. CONSTITUTION:Pseudo noise code generators 1, 13 generate respectively pseudo noise codes S1, S2, and S3, S4 having the same pattern in a period T and different from the phase by T/2 and the information signal is modulated by both the codes S1, S2 at level 1 and only the code S1 at level 0. If the codes S1, S2 and S3, S4 are not synchronized at the receiving side, a synchronizing circuit 30 is set to the search mode and changes the phase of the codes of the generator 13 and the frequency of a voltage controlled oscillator 19 respectively to make the phase coincident with the phase of the codes of the generator 1. Further, the circuit 20 goes to the tracking mode and accurate synchronism is attained. Thus, a narrow band filter at the receiving side is not required to prevent the code error of the information signal caused by the synchronism of the pseudo noise code.

Title: Compensating method for transmission delay time
Inventor: TSUNODA REIKICHI
IPC: H04L7/00
Filed: 1979-03-30
Abstract: PURPOSE:To enhance the transmission efficiency by securing the individual setting for the dummy field length within the time slot of each channel. CONSTITUTION:The answer-back is caught from traffic controller TC through synchronous/control start coupler SC1 via the individual oscillation to remote stations AM1-AMk each. At the same time, the reciprocating delay time is measured previously between coupler SC1 and each remote station and then memorized. The data field corresponding to each remote station is transmitted after synchronous/ control signal SYC from controller TC. In addition, controller TC adds dummy field DUM featuring the signal reciprocating delay time 2td1, 2td2 ... against each remote station to each data field and every time the data field of each channel is transmitted. As a result, the waste time can be reduced by 2(tdmax-tdi) per channel to enhance the transmission efficiency of the circuit in comparison with the case in which the DUM is set even to maximum delay time tdmax.

Abstract: PURPOSE:To prevent leads from being deformed as well as to take widely the area of a place for mounting a chip capacitor and a resistor, which are provided under a package, by a method wherein protrusions are provided inside the positions of the points of the J-type leads on the rear of a package main body and/or between the leads on the side surfaces of the package main body. CONSTITUTION:Protrusions 3 are formed on farther inside than positions, where leads 2 come into contact with the rear of a surface package-type IC package main body 1. Thereby, in the case where the leads are subjected to elastic deformation by a stress, which is applied in the perpendicular direction of the leads, the protrusions 3 play the role of a slip resistance and the plastic deformation of the leads can be prevented from being generated. The space confined between the two protrusions 3 is widely taken. When not only the protrusions 3 on the rear of the package main body 1 but also protrusions 4 are formed between the leads on the side surfaces of the package main body, the leads can be prevented from being moved to their left and right directions. Accordingly, the deformation of the leads is prevented from being generated and at the same time, the area of a place for mounting a chip capacitor and a resistor, which are provided under a package, is widely taken.
