Title: Protective apparatus for guide vane of hydraulic turbine
Inventor: OOTA JIROU
IPC: F03B3/18
Filed: 1977-11-28
Abstract: PURPOSE: To provide a protective apparatus for guide vane of hydraulic turbine which allows easy and safe replacement of a connecting pin for connecting control links without disassembling a guide vane control mechanism such as control link or the like.  
     CONSTITUTION: In a connecting pin 5 for connecting control links 4, 31 and 32 for controlling the guide vane, the central sliding section 53 is divided into a braking device member 5a yielding a resistance force and weak member 56 having a weak section 51. The weak member 5b is inserted from below the control link 32 and then, supported by a support plate 9 and thus, a butt construction is formed with a butt plane 5c. With such an arrangement, in case the weak section is broken, all that is needed is remove the support place to replace the weak member 5b with new one. This eliminate the need for disassembling any member other than the support plate 9, thereby allowing easy and safe replacement of parts.

IPC: F24F13/22
Filed: 1986-06-18
Abstract: PURPOSE:To afford both stability and strength to the wagon and to make it possible to stably place a tank thereon by fixing a planer tank table for placing thereon a drain strage tank to a pair of connecting tools, and also fixing thereto a tank receiving plate having means for preventing a pair of frame members from overthrowing. CONSTITUTION:During the operation, the tip end of a drain hose is inserted into a water feed port 32 and a holding metal fitting 28 is suspended on a tank 26. At this time, since the holding metal fitting 28 has a profile sufficiently large with respect to the outer circumference of the tank 26. it is applied thereto as if it were embracing the tank 26. Although a slight sag is produced by the holding metal fitting 28, three corners of the tank 26 are held by the holding metal fitting 28 and one corner thereof is held by the tank receiving plate 27, thus preventing the tank from overthrowing. Since the pair of frame members 13 and 14 are constituted by fixing mounting rails 15, tank table 22 and tank receiving plate 27, and these are assembled by connecting bars 17 and 18 extending perpendicularly thereto, the frame members 13 and 14 are enhanced in strength.

Title: High power hibrid integrated circuit
Inventor: AOKI HIDEAKI
IPC: H01L23/28
Filed: 1981-09-08
Abstract: PURPOSE:To prevent the breakdown of package in the thermal impact test due to the difference of thermal expansion coefficients of a resin and a metal plate by sealing a hybrid integrated circuit provided between the pair of metal plates located in parallel with the resin. CONSTITUTION:Metal plates 3 and 4 are located in parallel and a hybrid integrated circuit provided between them is sealed by a resin 5. Thereby, the internal stress due to a slight difference of thermal expansion coefficients of the resin and metal plate is concentrated to the bonding area of the resin and metal plate without resulting in separation. Moreover, such internal stress is cancelled by the opposing metal plates, thus drastically improving the thermal impact resistance. In addition, the transfer mold method can be employed, followed by improvement in the mass-productivity, and other characteristics such as the pressure-cooker resistance, chemical resistance and oil resistance are as much enhanced as compared with a current hollow package.

Filed: 1982-08-17
Abstract: PURPOSE:To increase mechanical strength and to improve fixing performance and the durable number of copies, by providing a silicone rubber coating layer around a roll core bar and forming a coating layer of fluororubber thereupon. CONSTITUTION:Addition reaction type silicone rubber is formed by injection around the roll core bar made of aluminum and cured by being heated at 70 deg.C for two hours.

Title: Treating method of emulsion produced in process of oil acid removal
Inventor: SHIMAZU KIYOTAKA
IPC: B01D17/02
Filed: 1979-11-02
Abstract: PURPOSE: To perform a complete emulsion treatment by using a three-phase-separation, centrifugal-settlement separation process to separate an emulsion produced in an oil acid-removing process into the three phases of light liquid, heavy liquid, and solid.  
     CONSTITUTION: An oil-alkali emulsion 9 is supplied via pump 10 to a three-phase centrifugal separator 11 by which a strong centrifugal force, say, 3,000G or more, is applied to the emulsion. This causes the emulsion-constituting particles to either float up or settle down and, at the same time, the solid to be settled and separated. Thus the emulsion is separated into three phases-oil 12 as light liquid, alkaline liquid 13 as heavy liquid, and sludge 13 as solid; they are discharged separately. This allows the reutilization of the separated oil and alkaline liquid which are returned to the system. The sludge is recovered into a sludge tank for the use as a different application.
