Title: Memory access control system
Inventor: AIMOTO TAKESHI
IPC: G06F13/16
Filed: 1988-06-24
Abstract: PURPOSE:To improve the memory through-put of an information processor by constituting the information processor being capoable of outputting a bus right request from a storage control device to a bus arbiter when a request exists in the storage control device. CONSTITUTION:At the time of requiring the bus right of an S bus 300, bus requesters in instruction processors 10-a, 10-b, I/O processors 10-c, 10-d, and the storage control device 100 send bus right request signals 12-a to 12-d to the bus arbiter 20 in the device 100. The bus arbiter 200 waits the idle state of the bus and receives a request with the highest priority at a point of time corresponding to a bus idle cycle. The requester obtaining the bus right sends a request through the S bus 300. The device 100 checks whether a request address is included with the address setting range of the device 100 itself or not and receives only a request fitted to the address range. Thus, a memory access request is processed at a memory access time pitch, so that the through- put is improved.

Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To realize a friction welding method without a generation of unwelded parts by installing a grooved backing plate on the reverse face of a workpiece right under a tool, which is inserted to the welded part of the workpiece and moves while rotating. SOLUTION: A groove 7 made on a backing plate 2 is placed right under a welding face 3 of the workpiece 1, and welding is performed while a tip 4a of a tool 4 is inserted until it penetrates the reverse face of the workpiece 1. In this welding method, a part of the workpiece 1 is plastic flowed to the groove 7 made on the backing plate 2. During the welding processing, since the welding surface is being plastic flowed by the pressure of the tool 4, when the groove 7 is filled with metal, the metal on the welding part surface is decreased to make a concave form. The metal, which is to fill the groove 7, is supplemented by forming a projection 8 on the welding surface in advance. The tip 4a of the tool 4 is preferred to be welded while moving in the groove 7 of the backing plate 2.  In this way, the overall of the welding part is fused are eliminates unwelded parts by deleting the backing waves.

Title: Total power generation device through application of principles
Inventor: SHIMADA EIJI
IPC: F03B17/06
Filed: 1992-05-01
Abstract: PURPOSE:To increase the power generation capacity of a hydraulic power generation device and a thermal power plant by maximizing the utilization of a water flow, and generating power via the arbitrary combination of a plurality of principles including the principles of hydraulic power and lever, and Pascal's principles of buoyancy and gravity. CONSTITUTION:Running water is introduced from a river 1 to a penstock 2. In this case, the diameter of the penstock 2 is gradually narrowed toward a downstream to increase the pressure of the running water. Thereafter, the water is caused to fall on a hydraulic turbine at a hydraulic power plant, thereby increasing power to drive a generator 22. Then, the running water weakened in flowing force is delivered to a buoyancy outer tank 17 and as a result, a buoyancy inner tank 16 becomes afloat, due to the pressure of the running water. The tank 16 continues to rise and causes a buoyancy tank-generator transmission shaft to rotate, thereby driving the generator 22. According to this construction, when a hydraulic power plant currently under operation needs updating due to deterioration, a conventional storage reservoir and a regulating reservoir channel can be used as they are, and conventional output capacity can be increased to a maximum level. In addition, the benefit of nature can be maximized without any public nuisance.
