Title: Wavelength multiplexed optical communication network
Inventor: NAGATSU HISAHIDE
IPC: H04B10/27
Filed: 1992-09-17
Abstract: PURPOSE:To obtain a network with the same total node number with a fewer wavelength number by linking ring networks having two nodes or over via a coupling means having wavelength distribution confluence performance so as to use the wavelength again. CONSTITUTION:A wavelength lambda1 is allocated for the communication between nodes 1, 2 in a ring network A and the wavelength lambda1 is allocated again for the communication between nodes 3, 4 in a ring network B and between nodes 5, 6 in a ring network C respectively. Then number of total wavelength to be required is 13. The re-use of the wavelength lambda1 is attained by using wavelength distribution confluence coupling means 21, 22. The wavelength used only for the communication between nodes in a ring network is used in common for the wavelength used only for the communication between nodes in other ring network or the wavelength used only for the communication between nodes in plural ring networks is used for the wavelength used only for the communication between nodes in other plural ring networks and then the re-use of the wavelength is attained.

Title: Medical oxygen inhaler
Inventor: KOBAYASHI TERUO
IPC: A61M16/00
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To avoid such an unfavorable accident that a specified amount of oxygen which is set by a flow rate setting apparatus is not supplied to a patient due to leakage of oxygen at an connecting part, by providing with a flow meter by which flow amount of oxygen supplied to a supplying circuit of oxygen is displayed. SOLUTION: Oxygen which is discharged from an oxygen supplying source 1 is set at a specified flow rate which is determined by a diameter of an orifice by means of a flow rate setting apparatus 2, and is supplied to a patient P via a humidifier 3 through, for example, a cannula for oxygen inhalation. A flow meter 5 by which flow rate of oxygen is displayed is provided in the neighborhood of the cannula 4. The indicating position of the flowmeter 5 is lowered when liquid resistance is generated due to such a condition that the filter in the humidifier 3 is blinding and the cannula 4 or a connecting hose is folded. Thereby, unusual condition of the oxygen supplying circuit such as a shorting condition of oxygen supplying amount to the patient can be confirmed easily from outside of the device through the flowmeter, and can be dealt with quickly.
