Title: Fifo type memory circuit
Inventor: ABE SUSUMU
IPC: G11C7/00
Filed: 1992-02-28
Abstract: PURPOSE:To more accurately prevent the generation of the full or the idle state of a memory. CONSTITUTION:The devided region deviding in advance the region of a memory 103 is determined. At every interval of inputting data, while an address counter for writing 104 successively increases the write address of the memory 103, the address is coded by an encoder 106 and sent to a comparator. At every interval of outputting data, while an address counter for reading 113 increases the read address, the address is coded by an encoder 115 and sent to a comparator 121. The comparator 121 compares both addresses with each other and prohibits the increments in the write address counter 104 or the read address counter 113 according to the relation between the devided region being a writing object and the devided region being a reading object. The encoders 106, 115 code the address according to the encoding rule so that only one bit of the coded address values before the increment has an inverted value.

Abstract: PURPOSE: To obtain reliable removal protective tubular coupling function by constituting that a lock ring may not be inadvertently expanded in its diameter.  
     CONSTITUTION: To being with, a lock ring 13 is brought to be tucked into an annular groove 14, a convex part 16 of the ring 13 is brought to correspond with a concave part 15 of the groove 14. Then, when an inserting port 2 has been inserted into a receiving port 1, the ring 13 is pushingly expanded through a boss 12 of the inserting port 2 into the concave part 15 of the groove 14, the boss 12 of the inserting port 2 passes through the ring 13. After passing therethrough, turning of the inserting port 2 turns the ring 13 with an operating boss 18 positioned between split ends 13a, 13b, which lets the convex part 16 internally tucked with the bottom surface 17 of the groove 14. After that, the ring 13 comes to be in diametrally contracted condition, which makes it possible to be in mesh with the boss 12 of the inserting port 2. Subsequently, coupling work is completed in the sequence that arrangement of a seal material 3, a split ring 8 and a push-in ring 9 is done through the gap made by the tip surface of the inserting port 2 and the back end section of the receiving port 1 in the tubular inner surface, and contraction of the seal material 3 is done by a push-in bolt 10.

Title: Optical star coupler
Inventor: TAKAMI MASAYUKI
IPC: H04B10/27
Filed: 1993-03-04
Abstract: PURPOSE:To provide an optical star coupler in which the receiving part of each terminal can always receive an optical signal by a constant threshold value and gain. CONSTITUTION:Optical information signal as an information medium is transmitted from the transmitting part of each terminal to an optical star coupler 4, in a star-shaped transmission system constituted of the plural terminals. Those optical signals are coupled by an optical coupling part 1 in the optical coupler, and inputted to an optical fiber amplifier 2. The optical fiber amplifier 2 possesses a saturating characteristic area for an input and output signal, and the output signal level of the optical signal inputted to the optical fiber amplifier 2 is amplified to a decided value regardless of the signal level. Thus, the optical signal can be always received by the constant threshold value and gain at the receiving side by re-transmitting the output signal from an optical branching part 3 to each terminal.
