Filed: 1988-11-14
Abstract: PURPOSE: To reduce cost by dividing blades of axially mutually opposite blade wheels into sectors distributed circumferentially, and arranging blades slanting in the direction opposite to the circumferential direction, succeeding to the sector having blades slanting in the circumferential direction. CONSTITUTION: The blades 5 of a stator blade wheel in the drawing are divided into pairs of sectors A, B. The blades 5a in one sector A are slanting in one circumferential direction, while the blades 5b in the other sector B are slanting in the other circumferential direction. The blades of a rotor blade wheel are arranged in approximately the same way as those of the stator blade wheel 4. Thus, during the rotation of the rotor blade wheel, the position of trailing blades and the position of leading blades alternate. This equals to rotation in both directions. Therefore it is possible to produce an equal operation in both directions of rotation with only one pair of blade wheels.

Abstract: PURPOSE:To realize a gas-insulated transformer which can be transported by a freight train and whose capacity is large by a method wherein at least a transverse reinforcement beam can be attached or removed out of a longitudinal reinforcement beam and the transverse reinforcement beam which are attached to the outside of a tank. CONSTITUTION:An upper-part transverse reinforcement beam 20 and a lower-part transverse reinforcement beam 21 which are attached to the transverse direction on the side face of a curved surface plate 1b are constituted so as to be capable of being attached or removed. Bases 22, 23 for fixation use which tighten and fix the transverse reinforcement beams 20, 21 by using bolts or the like are attached to the side face of the curved surface plate 1b. By this constitution, a gas-insulated transformer can be transported in a state that the upper- part transverse reinforcement beam 20 and the lower-part transverse reinforcement beam 21 which are attached to the transverse direction on the side face of the curved surface plate 1b have been removed. Since the width L2 of a tank at its transportation becomes smaller than a permissible value l in the width direction at its transportation by a freight train, it is easy to set the width within a limit size A at its transportation by the freight train. When the transformer is installed in a site, the upper-part transverse reinforcement beam 20 and the lower-part transverse reinforcement beam 21 are attached. Thereby, the gas-insulated transformer whose capacity is large can be installed without damaging the internal-pressure strength of the tank.

Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent a recurrence of knocking by changing reset speed to faster speed when advance correction is executed in acceleration being completed in a device for delay-correcting ignition timing in knocking and advance- correcting the delay quantity so as to be gradually reduced to zero at a specified reset speed. SOLUTION: In a control unit U inputting detection signals of various sensors including a knocking sensor S3 during the operation of an engine, a basic injection timing θB is set on the basis of the intake air quantity and engine speed. Whether acceleration is detected is then discriminated, and at the time of detecting acceleration, knocking delay (delay quantity = θK) is performed. this delay quantity θK is advance-corrected so as to be gradually reduced to zero. When the delay quantity θK is not zero within a specified period of a flag being set to 1 from timing to be an acceleration completed time point, reset speed until the delay quantity becomes zero is changed to faster speed than normal. The prevention of the recurrence of knocking and improvement in accelerating property are therefore compatibly secured.
