Title: Time division multiplexing point to multipoint optical bidirectional transmitter
Inventor: KUMOSAKI KIYOMI
IPC: H04B10/572
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical bidirectional transmitter which can normally receive normal received light even when the transmitter receives the received light in such a state that reflected light is superposed upon the received light. SOLUTION: A center-side device 1 is connected to each subscriber-side device 2i through an optical star coupler 3. The center-side device 1 transmits time division multiplexed outgoing transmitting light to each subscriber-side device 2i and each device 2i receives transmitted signals addressed to the device 2i. Each subscriber-side device 2i transmits incoming transmitting light within the time domain assigned to the device 2i. The center-side device 1 designates the position of the incoming optical signal of each subscriber-side device 2i so as to prevent the collision among the incoming transmitting light. An AGC amplifier circuit 44 measures the peak power value of received signals converted into electric signals by means of an electrooptical converting circuit 13 from a transmission line.  A TDM control circuit 50 assigns the incoming TDM time domain by designating the signal sending-out timing so that the received signals may form a line in the order of received photoelectric power in the ascending order based on the peak power value information of each subscriber- side device 2i.

Title: Gas generating agent composition containing d,l-tartaric acid
Inventor: MAIKERU UIRIAMU BAANZU
IPC: C06D5/06
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To facilitate an aqueous processing, and reduce energy and labor cost in a gas-generating agent containing fuel and an oxidant by using tartaric acid, especially d, l-tartaric acid as a part of the fuel.  
     SOLUTION: A fuel and an oxidant constitute 15-60wt.% and 40-85wt.% of this gas-generating agent, respectively. In the composition, 10-100wt.% of the fuel is tartaric acid, and when a racemic compound or a d,l-mixture is used, aqueous processing is improved from the case where l-tartaric acid derived from a natural product is used. The reason is that the solubility of l-tartaric acid in water is 139g/100ml at 20°C and that of d,l-tartaric acid is 20.60g/100ml at 20°C. Therefor, a gas-generating agent using l-tartaric acid is very difficult to be dried. Besides, d,l-tartaric acid dissolves in water sufficiently for facilitating an aqueous processing, and at the same time the d,l-tartaric acid is easily dried. As the other part of the fuel, a non-azide fuel is preferably used. Potassium perchlorate, etc., is used as the oxidant.
