Title: Optical communication transmission system
Inventor: HENMI NAOYA
IPC: H04B10/2543
Filed: 1992-06-22
Abstract: PURPOSE:To enlarge a repeating interval and to reduce the cost of an entire system in an optical amplifying relay system. CONSTITUTION:It is necessary for the optical amplifying relay system to match a signal wavelength with a zero distribution wavelength in order to avoid the influence of the distribution of optical fibers. When a repeating output is increased more than +5dBm in the transmission using these optical fibers, however, transmission characteristics are degraded by non-linear effects inside the optical fibers being the transmission lines. Therefore, the output of the relay amplifier is limited and as a result, it is necessary to shorten the repeating interval. In order to avoid the non-linear effects inside these optical fibers, the distributed values of fibers 101, 111, 121, 131...191 for transmission are set excepting for zero for each relay block, and optical fibers 102, 112, 122, 132...192 are inserted for compensating the wavelength distribution of these fibers for transmission. Thus, an optical multistage relay system not to degrade the transmission characteristic even by the high repeater output about +10dBm can be constructed.

Title: Josephson junction memory chip
Inventor: TAKAHASHI TSUNESUKE
IPC: G11C11/44
Filed: 1983-09-05
Abstract: PURPOSE:To increase the chip memory capacity without using many Josephson junction gates within a chip by circulating the information of large capacity to a super conduction loop connecting a transmission line, a writing gate of Josephson junction, an earth source and a sense gate control line. CONSTITUTION:If a remote terminal 35 of a transmission line 31 is short-circuited to an earth source 33, the current pulse trains have the same polarity with no attenuation and are totally reflected. Thus the delay time is equal to about double as much as the delay time between the near remote terminals of the line 31 when viewed from a near terminal 34. When a writing current pulse train Iw is supplied from a generation source 32, a writing gate 12 of Josephson junction is immediately switched to a voltage state from a superconduction state in case a control current Iy is impressed to a control line 15. Then the train Iw is switched to the side of the line 31 and then reflected by the source 33 via a sense gate control line 13 at the terminal 35. The train Iw is sent back to the terminal 34. The drive of the Iw is stopped immediately before the terminal 34, and at the same time the impression of the current Iy is cut off. Then the gate 12 is reset to the superconduction state from the voltage state. Thus the Iw passes again through the gate 12 and is totally reflected by the source 33.

Title: Storage circuit
Inventor: KOJIMA MASANORI
IPC: G01P13/04
Filed: 1980-11-18
Abstract: PURPOSE:To obtain a storage circuit which is cheaper than an integrated circuit and has high reliability and occupies less area, by applying a trigger signal to the base of a transistor and by applying an input pulse to an emitter and by connecting a capacitor to a collector. CONSTITUTION:A D type FF20 consists of a transistor TR22, a resistance 21, and a capacitor C23. When a positive-polarity pulse is applied to a trigger terminal 11 connected to the base of the TR22 through a resistance 21 for limiting a current, the input pulse charges the C23 through the path between the base and a collector to make an output terminal 13 positive in potential if the input of a data terminal 12 is positive. If the terminal 12 is zero when the positive-polarity pulse is applied to the terminal 11, the circuit between the collector and the emitter of the TR22 becomes conductive, and the C23 is discharged, and the potential of the terminal 13 becomes zero. Even if the input pulse disappears, the C23 holds the potential till recharging due to leakage or natural discharging. Thus, the circuit consists of individual parts and is cheaper than the integrated circuit and has high reliability and does not require a power source.
