Patent JP-S6132354-A (JP)
Title: Manufacture of plastic exterior battery
Inventor: SUZUKI MASANORI
IPC: H01M50/562
Filed: 1984-07-23
Abstract: PURPOSE:To achieve excellent liquid leakage resistance of the areas formed by fusing metallic terminals to the plastic exterior case for generation elements by inserting the metallic terminals into concave areas formed in the plastic case while vibrating the metallic terminals by ultrasonic waves. CONSTITUTION:After a concave area 3 into which a metallic terminal 4 is to be inserted is formed in a plastic case 2, the terminal 4 is inserted into the concave area 3 while being vibrated at a frequency of about 19kHz by means of an ultrasonic oscillator to produce frictional heat which melts the surface of the concave area 3 before it is cooled, thereby fixing the terminal 4 in the concave area 3. Next, after current collectors 8 and 10 are brought into contact with terminals 4 and 6, a positive and a negative active material 12 and 14 and a separator 16 are placed inside the current collectors 8 and 10 before a lid 18 is fused, thereby constituting a plastic exterior case. As a result, the terminals 4 and 6 are reliably fused to the plastic case 2, thereby preventing any leakage of electrolyte.

Title: Quasi-synchronous buffer control system
Inventor: SHIGAKI SEIICHIRO
IPC: H04J3/06
Filed: 1985-07-12
Abstract: PURPOSE:To improve the reliability of connection between a domestic line and a satellite line by dividing slip control into a synchronous system and a data system to reduce the distortion of a PCM signal accompanies with slip control. CONSTITUTION:The PCM signal from a ground (or satellite) line is written in a memory circuit 7 and is read out thereafter. In such a case, when phases of a synchronizing signal 15 for write and a synchronizing signal 21 for read approach each other, a comparing circuit 5 sends a read address slip control signal 23 of the synchronous system to a control circuit 9, and the circuit 9 performs repeat/delete operation of the read address in multiframe units. When phases of a data phase signal 16 for write and a phase signal 22 for read approach each other, a comparing circuit 6 sends a read address slip control signal 24 to a control circuit 10, and the circuit 10 performs repeat/delete operation of the read address in one-frame units. Thus, the synchronizing signal and the data signal perform the slip operation independently.
