Title: Traffic control system and control method, and medium containing program therefor
Inventor: TOYAMA MASAKAZU
IPC: G08G1/07
Filed: 2001-02-06
Abstract: PROBLEM TO BE SOLVED: To solve the traffic congestion problem by independently controlling an intersection where a bottleneck might occur separately from a sub-area. SOLUTION: This system is provided with an arithmetic processing part 13 for measuring the traffic quantities of intersections, judging an intersection to form the bottleneck causing the traffic congestion, independently controlling the intersection forming the bottleneck separately from the sub-area, and temporarily reconfiguring a new sub-area with the remaining intersections. The intersection where the occurrence of the bottleneck is judged is separated from the sub-area and removed from a system control to independently operate, and the remaining intersections temporarily constitute another sub-area never influenced by the bottleneck intersection. A point control is performed in the bottleneck intersection to reduce the wasteful blue time of a traffic signal controller 1, and an effective traffic flow is obtained to solve the traffic congestion problem.

Title: Screw compressor
Inventor: WATANABE ATSUSHI
IPC: F04C29/02
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a screw compressor with a highly efficient and compact oil separating mechanism built in it. SOLUTION: In the screw compressor, a cyclon type oil separator is provided in a discharge casing and, a main oil reservoir chamber formed on just below a cyclon inner cylinder and an auxiliary oil reservoir chamber partitioned by a bulkhead are provided by dividing an oil reservoir chamber in two chambers low in height. A main communicating passage to communicate the main oil reservoir chamber and a lower part of the auxiliary oil reservoir chamber with each other and an auxiliary communicating passage to communicate an upper part of the main communicating passage are formed on the bulkhead. A main oil reservoir oil level becomes higher toward a wall surface from the central neighbourhood by a revolving current in the inside of a cyclon during operation of the compressor, but an auxiliary oil reservoir oil level keeps roughly horizontal.  Consequently, the oil in the risen amount flows to the auxiliary oil reservoir chamber through the auxiliary communicating passage, and abnormal rise of the oil level is prevented. Consequently, lowering of oil separating capacity of the cylon type oil separator is prevented so that the oil is not taken away as the oil level approaches a cylon inner cylinder lower end surface.
