Title: Tuyere for blast furnace
Inventor: NAKAMURA YUKIO
IPC: C21B7/16
Filed: 1980-03-31
Abstract: PURPOSE:To obtain a tuyere for blast furnaces which is easy to assemble, has no danger and permits the completion of the work in a short time, by providing a sloped part eliminating a level difference to the level difference part between the inside circumferential surface of a large tuyere mouth part and the inside circumferential surface of a body part or to the level difference part between the outside circumferential surface of a small tuyere root part and the outside of the body part. CONSTITUTION:A large tuyere 5' fitted at its root part 6 tightly to the supporting port part 4 of a large tuyere bracket 3 fixed to a furnace wall 1 is formed at the inside diameter of its mouth part 7 smaller than the inside diameter of its body part 10. The boundary between the mouth part 7 and the body part 10 is a level difference part A, but only the range of approximately 60 deg. on the lower side is formed to a sloped part 15 to provide a slip way migrating naturally from the inside circumferential surface 7a of the mouth part 7 to the inside circumferential surface 10a of the body part 10. Namely, if a small tuyere 8 is inserted into the deep part of the large tuyere 5' and if this small tuyere 8 is further pushed in which its vertical position is held correctly maintained, the root part of the small tuyere 8 is shifted along the sloped part 15 providing the slip way to the inside of the mouth part 7 of the large tuyere 5', whereby the root part 9 is tightly fitted into the mouth part 7.

Title: Fuel rod spacer
Inventor: HOSHIIDE AKIHIKO
IPC: G21C3/34
Filed: 1988-02-26
Abstract: PURPOSE:To reduce pressure loss of coolant flow and improve the limit output of an fuel assembly by setting a conical projection in a lattice frame of a fuel rod spacer. CONSTITUTION:A lattice partition space 4 in which a fuel rod is inserted by a side frame 2 and a lattice frame 3 is formed to be a fuel spacer 1. Conical projections 5 extending upward and downward of a fuel spacer 1 are set on the crossing part of the lattice frame 3. The conical projections 5 form the peaks on the lines extending upward and downward of the crossing parts of the lattice frame 3 and is formed so as to make rills of the center part between the crossing parts. Elastic supporting fittings 6 supporting a fuel frame are jointed so as to sandwich the lattice frame 3 by both upper and lower ends thereof and slender streamline fixed projections 7 are set on the center of the lattice frame 2 and the side frame 2. Thus, since a sudden change of flow passage cross section in the neighborhood of the spacer is eliminated, pressure loss is reduced and liquid film breakage on the surface of the fuel rod is eliminated, the limit output of an fuel assembly can be improved.

Title: Hybrid four-wheel drive vehicle
Inventor: ARAI KENTARO
IPC: B60L50/16
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain a hybrid four-wheel drive vehicle which prevents its hunting from being generated even under a condition under which the slipping of motor-driven wheels is generated, by a method wherein, after the drive of the motor-driven wheels is started, the motor-driven wheels are stopped when the pushing amount of an accelerator pedal is at a specific value or lower irrespective of the difference in a rotational speed between engine-driven wheels and the motor-driven wheels. SOLUTION: An electrically driven motor 5 and a clutch 6 are controlled by a controller 1 to which signals from a front-wheel speed sensor 8 used to detect the rotational speed VF of front wheels 1, from a rear-wheel speed sensor 9 used to detect the rotational speed VR of rear wheels 2 and from an accelerator sensor 10 used to detect the pushing amount AP of an accelerator pedal are inputted. Its control content judges whether a vehicle speed V is at a prescribed threshold value (e.g. 15 km/h) or higher after the start of the drive of the rear wheels 2 on the basis of the control program of the motor-driven wheels 2, and it discriminates whether the pushing amount AP of the accelerator pedal lowers a threshold value (e.g. 10%) when the vehicle speed V is lower than the threshold value.  Then, when the pushing amount AP is lower than the threshold value, the drive of the rear wheels 2 is stopped.

Abstract: PURPOSE:To secure lubricating reliability in each compressor by making the operating frequency of a compressor being low in oil level height higher after operating each compressor with the same capacity just before stopping refrigerating cycle operation. CONSTITUTION:Before fully stopping refrigerating cycle operation, a command is issued to both first and second inverter units 3, 4 so as to make them operate each of compressors 1, 2 with the same operating frequency.
