Title: Transient current detecting device
Inventor: YAMAGUCHI HIROAKI
IPC: G01R19/15
Filed: 1989-12-13
Abstract: PURPOSE:To improve response speediness with a small-sized, inexpensive device by processing the waveform of the output of a current detection line which is close and parallel to an electric conductor where a transient current flows. CONSTITUTION:When a short-circuit current flows through the electric conductor 5, magnetic flux is produced in the direction of a right-handed screw rule. When the current detection electric conductor 6 is put close to lines of the magnetic flux in parallel, electromotive force is generated on the electric conductor 6 corresponding to the quantity of variation of the magnetic flux and the detection current 8 flows. The quantity of magnetic flux cut by the electric conductor 6 is proportional to the electric conductor length l and the value of the electro motive force is adjustable with the length l of the electric conductor. Then only one electric conductor 6 is provided to reduce the inductance and follow up the short-circuit current speedily.

Title: Memory controller
Inventor: MARUYAMA TERUYUKI
IPC: G11C11/406
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of the memory access speed by deciding the urgency of memory control based on the number of stored memory access requests and the number of pending refresh operations. SOLUTION: A bus 1-I/F selector 102 receives the memory access requests from a bus 101 to divide them into the requests S1a and S1b at each preference level of requests and queues them into the request queues 103a and 103b. An arbitration circuit 105 receives a refresh request S2 from a refresh circuit 104 and the requests S1a and S1b from the queues 103a and 103b respectively and arbitrates these requests. A reply data production part 108 produces the reply data based on the data S6 obtained from a memory device 107 and the request information S7 and queues the reply data into a replay queue 109. A bus-I/F 110 fetches the replay data and gives a reply to a processor.

Title: Descaling method
Inventor: ROKUTANDA HITOSHI
IPC: B24C11/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of wear of those consumable parts such as injection material and the liners and impeller blades inside the injection chamber of an injection device by accelerating the injection material of a specific gravity to a prescribed speed and removing oxidized scales adhered to the surface of a part to be treated. SOLUTION: The specific gravity of injection material is 11 to 20. When it is less than 11, a sufficient descaling effect cannot be obtained, and when it exceeds 20, it will be difficult to obtain a material with a strength suitable for injection material. The injection speed of the injection material should be desirably 10 to 40m/sec. However it is more desirable to be 15 to 35m/sec. If the injection speed is less than 10m/sec., a sufficient descaling cannot be performed, and if it exceeds 40m/sec., the surface roughness of a part to be treated will become too large and the service life of the injection material will be shortened.

Abstract: PROBLEM TO BE SOLVED: To prevent the inner surface of a seal ring from being burned out by providing a low frictional intermediate ring of a specific diameter concentrically on a sliding surface with the inner side surface of a seal ring box which is fitted loosely on the outer periphery of a rotating shaft. SOLUTION: In a shaft sealing device used for the shaft sealing part of a turbo machine, a rotating shaft 20 is passed through a casing 10, and a seal ring 50 is installed between them. Also the seal ring 50 is moved in the axial direction by a difference in pressure between a high pressure chamber 30 and a low pressure chamber 70, and pressed against the end surface C of the casing 10 through an intermediate ring 80.  In this case, because the end surface of the intermediate ring 80 is brought in contact uniformly with the casing 10 even if such a positional relation is provided that a diameter clearance as a difference between the inner diameter of the intermediate ring and the inner diameter of the casing 10 is approximately zero rather than a diameter clearance as a difference between the inner diameter of the seal ring 50 and the outer diameter of the rotating shaft 20, the seal ring 50 can smoothly follow the variation of the rotating shaft 20 in radial direction.

Title: Hot water feed system
Inventor: SHIMIZU TOMOYUKI
IPC: F24D17/00
Filed: 1988-12-23
Abstract: PURPOSE:To prevent the feed of hot water with temp. different from a set hot water temp. and the occurrence of hunting phenomenon during correction of a feed hot water temperature by providing a hot water temperature correcting means which corrects a deviation between a hot water temperature detected by a temperature sensor and a set hot water temperature through a delay means when the deviation exceeds a given value. CONSTITUTION:A deviation between a hot water temperature detected by a temperature sensor 41 and a set hot water temperature is detected by a computing circuit 34. When the detecting deviation exceeds a given value, for sample, 1 deg.C, the deviation is corrected through a delay means, formed with the three- second timer, by means of a hot water temperature correcting means formed with a CPU 31. Thus, hot water having temperature different from a set hot water temperature is prevented from being fed. Further, since hot water temperature is corrected by using the delay means to check a deviation at intervals of three seconds, even when overshoot or undershoot occurs to an automatic hot water temperature regulating mechanism, hunting phenomenon is prevented from occurring.
