Patent JP-S62210298-A (JP)
Title: Motor-operated blower
Inventor: YAMAURA IZUMI
IPC: F04D29/28
Filed: 1986-03-07
Abstract: PURPOSE:To prevent air flow from burbling over a blade surface and to reduce noise and vibration by arranging an annular groove on a back shroud to make spaces between blades communicate with each other thereby equalizing differential pressures between rotation side and reverse rotation side of the blade. CONSTITUTION:An annular groove 13 is sunk on a back shroud 12. This eliminates surfaces warpage and extremely reduces surface displacement compared with conventional back shroud made of flat plate. This is because the groove 13 serves as a rib to increase the strength by a large margin. Another effect is that since the groove is sunk to cross under a blade 5, even if air flow tends to burble on the blade 5, differential pressures between rotation side and reverse rotation side of the blade 5 is equalized through the groove 13 and air flows from X to Y as shown in the figure while preventing the burbling from occurring. And air flow between the blades 5 is balanced to stabilize performance. With the above-mentioned constitution, stabilization in performance and reduction in noise and vibration are made possible.

Title: Fuel injection valve
Inventor: NONOMURA TADASHI
IPC: F02M45/08
Filed: 1983-03-25
Abstract: PURPOSE:To facilitate regulation of fuel injection pressure and setting of initial lift at the start of main injection while to improve accuracy by means of first, second springs, initial lift regulating shim, main injection starting pressure regulating shim, etc. CONSTITUTION:When the pressure in an injection tube reaches to the initial injection starting pressure, a needle 7 will rise against first spring 13 while stop temporarily when the upper end 15a of first push rod will contact against the lower end 23b of second push rod. Here the lift (L) is adjusted by varying the thickness of initial lift adjusting shim 25. Upon reaching to the main injection starting pressure, the force for pushing up the second push rod 23 will exceed over the setting load of second spring 19, so the spring 19 is compressed to lift the entire stroke thus to perform main injection until lowering to the valve close pressure. The time required from the start of initial injection to the start of main injection can be set through adjusting of setting load of second spring 19.

Filed: 1990-03-02
Abstract: PURPOSE:To manufacture an oxide superconductive laminate in which a metal base and a superconductive material are not separated each other by laminating a ceramic layer, a precious metal layer and an oxide superconductive material layer on a metal base in said order. CONSTITUTION:An oxide superconductive laminate is composed of an intermedi ate layer consisting of a ceramic layer and a precious metal layer formed on a metal base and an oxide superconductive material layer on said intermediate layers and integrated together thereon. The intermediate layer composed of two layers of ceramic and precious metal acts synergistically on both of the metal base and the oxide superconductive material layer formed on the outer surface. Because of said action, respective layers on the metal base of the oxide superconductive laminate are stabilized, and release or crack is not gener ated even when the same is used in liquid nitrogen which develops superconductive characteristics. Also, the metal base and the superconductive raw material are not reacted at the time of calcination in any kind of superconductive materials. Its superconductive characteristics are higher than those of a single-layer intermediate layer.

Abstract: PURPOSE:To make it possible to measure the profile of a surface highly accurately by computing the minute suspending amount of a piece of wire as the reference of straightness based on the natural frequency of the wire, and compensating for the measurement error. CONSTITUTION:A piece of wire 2 such as a piece of piano wire is provided in parallel with an object to be measured 1. The wire 2 is made to be the reference of temporary straightness.

The natural frequency (f) of the wire 2 is measured with a detecting device 5. The suspending amount as the change in straightness of the wire 2 is computed with an operating device 6 based on the natural frequency (f). The measured value of the distribution of the distances is corrected with the suspending amount. Thus, the measured value of the profile of the surface is obtained highly accurately.
