IPC: H04M3/50
Filed: 1983-11-24
Abstract: PURPOSE:To transmit a message properly from the beginning even if plural callings continue by giving addresses respectively after dividing a voice message to plural messages, and instructing by pointers sequentially from the first address in accordance with the calling. CONSTITUTION:A central controller CC connects the calling which demands messages from plural trunks TR1-TRn to interfaces IF1'-IFm sequentially through a network NW, and connects the messages to a talkie device TS. The talkie device TS has a ROM, divides the message which is used exclusively for reading into the suitable length for each ROM, and gives a1-ax to the address. Respective interfaces have pointers P1-Pm. A pointer Pi of the interface which is connected to the trunk reads the messages sequentially from the first address a1 of the ROM, and transmits them to the trunk. Thus, the messages are transmitted properly from the beginning of the messages even if the calling continues in accordance with each trank.

Title: Exhaust emission control system for engine
Inventor: TAYAMA AKIRA
IPC: F01N3/08
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To completely release NOx stored in a NOx storage catalyst and prevent unpurified HC and CO from being emitted when an air-fuel ratio in exhaust gas is made temporarily rich for reducing and purifying NOx. SOLUTION: In this exhaust emission control system of an engine 1, a NOx storage catalyst 3 is provided for storing NOx in exhaust gas when an exhaust gas air-fuel ratio is lean and releasing the stored NOx for reduction and purification when the exhaust gas air-fuel ratio is stoichiometric or rich. An engine control unit 9 judges lowering of NOx storage ability of the NOx storage catalyst 3 caused by an increase of the stored NOx amount. When it is judged that the NOx storage ability is lowered, the stored NOx is released and reduced by increasing an air-fuel ratio intermittently for several times. Therefore, NOx stored in the NOx storage catalyst can be released completely.  An air-fuel ratio in the catalyst is maintained at a substantially stoichiometric ratio while an air-fuel ratio in the exhaust gas is made temporarily rich for reducing and purifying NOx, and unpurified HC and CO can be prevented from being emitted.
