Abstract: PURPOSE:To increase restricting force against vibration of a pipeline as to realize operation of high reliability by weldingly fixing the pipeline along a plurality of vertical ribs in a hydraulic machine provided with the vertical ribs and the pipeline on a side of an upper cover. CONSTITUTION:A plurality of vertical ribs 3 are housed inside an upper cover 2 for covering the upper portion of a runner blade 1.

The balance tube 5 is divided along a tube axis, and the obtained half-split balance tubes 5, 5 are weldingly fixed to the vertical ribs 3 in a manner facing to each other, thereby constituting a pipeline path. A part of the vertical rib 3 is cut at the inlet end 6a of the balance tube 5 so that an opening area of the inlet end 6a is equivalent to a cross-sectional area except for the vertical rib 3, i.e., a cross-sectional area inside of the balance tube 5 before splitting. Consequently, it is possible to reduce vibration generated when high pressure pulse water passes.

Title: Maltistage spiral pump
Inventor: INOMATA TAIJI
IPC: F04D1/08
Filed: 1980-12-16
Abstract: PURPOSE: To make it possible to have the size of required intake head reduced without using a low speed big pump by reducing and reversing the rotation of the first stage runnet down to the required rotational speed, increasing the pressure by sucking the lifting water, allowing the water to pass through the runners subsequent to the second stage making normal rotation with a high speed.  
     CONSTITUTION: The runner 9 of the first stage is so arranged to make a reverse rotation of reduced speed in relation to the rotation of runners of the stages subsequent to the second stage fixed on a pump-main shaft 1. Then, liquid exhausted from the runner 9 of the first stage smoothly flows into the runner 4 of the second stage rotating opposite direction to that of the runner 9 of the first stage while correcting its flow direction when passing the back side of first runner casing 6, and flows through runners of third, forth and next stage, then increases its pressure to have the specified pressure obtained. In this way, this small pump is enough for pressent requirement instead of a big low speed and expensive one if the smaller required intake head is needed.

Title: Method and apparatus for measuring strength of structure concrete
Inventor: SEKO SHIGEKI
IPC: G01N3/00
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To measure a strength of a concrete in the degree of a slight damage by injecting a water jet of a constant energy, drilling a structure concrete, and measuring a compression strength of the concrete. SOLUTION: The apparatus 1 for measuring a strength of a structure concrete generates a water jet W of a constant energy (a constant amount and a constant pressure) by a pump 2, injects a water jet W from a nozzle 3, and drills a structure concrete 8. A depth measuring instrument 5 provided in a water supply passage in the rear side of the nozzle 3 measures a depth of the drilled hole of the concrete 8 real time. A calculator 6 inputs output data of the instrument 5 through an electric cable 15, and divides an increment of a displacement of the depth of the hole by its predetermined time to calculate a drilling speed. The strength of the concrete is measured in real time from a relational formula between the drilling speed and the strength of the concrete.  Thus, since the degree of the damage to the structure can be made slight, the influence on a yield strength of the structure is small.
