Title: Fifo buffer control system
Inventor: YAMAMOTO TAKEHIKO
IPC: G06F5/12
Filed: 1990-07-24
Abstract: PURPOSE:To transfer data to a FIFO buffer at a high speed by controlling data write/data to the FIFO buffer in accordance with status information corresponding to the address value of a prescribed address destination. CONSTITUTION:When a write control signal WR is in the active state of the low level, a status latch 17 outputs the output of an OR gate 16, namely, the flag state of a selected flag register part as a ready signal RDY as it is; and when the write control signal WR is changed from the low level to the nonactive state of the high level, the status latch 17 latches the output of the OR gate 16 outputted till them and outputs it as the ready signal RDY. The ready signal RDY outputted from the status latch 17 is supplied to a write/read circuit to control the write operation of data to the FIFO buffer in the write/read circuit, namely, the generation of the write control signal WR. Thus, data is transferred at a high speed.

IPC: G21C7/16
Filed: 1987-08-05
Abstract: PURPOSE:To improve the safety of a nuclear reactor by providing a foreign matter capturing member into the hole of an upper side coolant flow passage. CONSTITUTION:An orifice 31 for throttling flow in order to optimize the flow rate of the coolant to a fuel assembly 30 is mounted on the coolant inlet hole 29 of a central part fuel supporting metallic fitting 28. There are a number of the orifices 31 which are different in inside diameter. The flow rate of the coolant to the assembly 30 can be changed by changing the orifice. A wire net 32 as the foreign matter capturing member is provided on the side hole which is the coolent inlet of a control rod guide pipe 25 existing on the front face of the orifice 31. The foreign matter such as metallic piece in the coolant is captured by this net 32.

Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility of movement in the longitudinal direction and generation of back lash by improving mounting stability. SOLUTION: In a state where mounting is completed, since the insides formed into U shapes in section of an upper end 1a and a lower end 1b of a glass inner 1 are formed a little narrower than the thickness of the trim outer upper part D21 and a trim outer lower part D22, the trim outer upper part D21 and the trim outer lower part D22 are pinched by the upper end 1a and the lower end D22 in the elastic contact state, the forming error of a door trim D is absorbed, and the stable attaching state can be secured. Since the trim outer upper part D21 and the trim outer lower part D22 are elastically pinched by the upper end 1a and the lower end 1b of the glass inner 1, they are not moved in the longitudinal direction, and backlash is not generated.

Title: Mixed combustion for disused material of high calorific value and that of high rate of moisture content
Inventor: FUKIHARU MINEO
IPC: F23G5/04
Filed: 1982-11-05
Abstract: PURPOSE:To reduce cost sharply of the titled operation by a method wherein the disused material having a high calorific value (hereinafter called material A) is burned in an incinerator, the resultant exhaust gasses are introduced into a drying furnace so as to dry the disused material having a high rate of moisture content therein (hereinafter called material B) and the dried disused material thus produced is supplied into the incinerator so as to be burned together with the material A. CONSTITUTION:Material A is burnt in an incinerator, the produced exhaust gas is charged into a drying oven supplied with material B for drying. Then the dried material B is burnt together with the material A, and after processing the then produced exhaust gas by an exhaust processing system, it is discharged into the atmosphere. By employing such an incineration method, only a single system is sufficient enough for the total system including an incinerator, exhaust gas processing and processes to follow thereafter. Because said procedure is to utilize the exhaust gas produced by burning the material A for preheating the material B, and it is burnt by the heat energy of burning the material A, the fuel which has been necessary for burning the material B in the conventional system is unnecessitated, a remarkable cost reduction can be realized.

Filed: 1983-10-20
Abstract: PURPOSE:To enable use of a soft magnetic body of the same shape regardless of range of testing pressure, by installing a non-magnetic ring, one end being contacting with the bottom of groove and the other end in flush with an opening plane of a soft magnetic material and a pressure sensor in the groove of the soft magnetic body contacting with it. CONSTITUTION:A non-magnetic ring 11 which is in flush with an opening plane of a soft magnetic body 1 is installed in a groove 3. In a pressure sensor thus constructed, pressure is applied on a non-crystalline magnetic alloy 6, a deforming port by strain is narrowed by a thickness of a non-magnetic ring 11, and consequently, a test pressure range extends to the high-pressure side. This leads to development of a pressure sensor of a different test pressure range by changing the thickness of the non-magnetic ring 11. Thus, by using the same magnetic circuit as well as detecting circuit, different pressure testing can be performed.
