Inventor: FUKASAWA HIROMICHI
IPC: A61M1/16
Filed: 1983-09-21
Abstract: An artificial lung (111) has an axially extending housing which accommodates a bundle of hollow fibers (116) retained within the housing (114) by a pair of walls (119,120) provided at the ends of the housing. The housing has blood inlet (129) and outlet ports (132) defining a blood chamber (128) within the housing. Oxygen gas is passed through the hollow fibers (115) and blood is passed through the blood chamber so that a gas exchange may take place through the hollow fiber walls. The artificial lung is provided with a blood reservoir chamber (131) integral with the blood chamber, so that blood which has undergone a gas exchange inside the chamber may be stored within the reservoir (131).

Abstract: It is known to include at least one additional transistor (T) in cascode connection with at least one component in integrated logic cir­cuits in order to avoid detrimentally high electrical fields in compo­nents of such circuits. The control electrode is then connected to one of  the power supply lines (V DD ). When the state of the logic circuit changes, switching currents generate voltage peaks on the power supply lines due to the inductance of these lines. Via the chip capacitance these voltage peaks jump from one power supply line to the other. Thus, a positive feedback loop is formed which comprises one power supply line, the chip capacitance, the other power supply line and the additional transistor. Instabilities are damped by inserting a resistance element (TR) between the control electrode of the additional transistor (T) and the power supply line (V DD ) coupled thereto.

Abstract: An optical transmitter having a single optical source (10) coupled to a modulator (14) for providing an information modulated signal and an optical amplifier (13) for providing an amplified phase reference signal which signals are combined by a coupler (15) for onward transmission. Duplex operation of a travelling wave optical amplifier 13 facilitates the implementation of a coherent optical transceiver 22 with a single optical amplifier (13). A separate reference signal oscillator, therefore, is not required at a remote receiver. The bi-­directional amplifier 13 also amplifies the incoming signal, removing the need for a separate dedicated amplifier before the receive (11). The transceiver may be adapted for homodyne or heterodyne operation.

Abstract: An auxiliary spotting optical system for binoculars and telescopes includes an auxiliary objective lens proximate the principal objective lens, a principal magnification system field of view indicator and an image transfer arrangement between the field of view indicator and the ocular lens of the binocular to bridge the optical gap created between the image plane of the auxiliary objective lens and the focal plane of the ocular lens to create an optical system delivering a 1x magnification to an observer with normal eyesight. A movable mirror in the optical path of the principal magnification system and the spotting system determines which optical system is active. In its first position the mirror directs light passing through the auxiliary objective lens, the field of view indicator, the image transfer arrangement to the ocular lens, and blocks the principal magnification optical path. The viewer is afforded a wide field of view without significant magnification with an indication of the area encompassed in the principal magnification field of view. The user can move the binocular until the target is within the field of view indicator. Shifting the mirror to its second position breaks the light path through the spotting system and opens the principal magnification optical path, and the target appears magnified to the power of-the principal magnification system.
