Title: Guide vane controller
Inventor: TAGUCHI KENJI
IPC: F03B3/18
Filed: 1979-04-11
Abstract: PURPOSE: To eliminate adverse effect of break of conventional weak pins on other functions in controlling guide vanes of a water wheel, by setting at least two weak points, different in strength, at junctions connecting arms of the guide vanes with a guide ring.  
     CONSTITUTION: When two adjacent guide vanes 2 bite a foreign matter A and an excess force is imposed on a connecting pin 5, the first weak portion formed on an external cylinder 5a of the pin is broken. At the same time an oil level switch 10 is actuated to interrupt a guide vane controller. Since the guide vane then functions being confined by the control mechanism at the second weak portion with a larger cross section on the inner side, the foreign matter A flows out. An inlet valve is then closed to interrupt the main machine. This construction can prevent continuous failure of weak portions, because water flow is reduced and the adjacent guide vanes never collide with each other, even if the inner weak portion with a larger cross section is broken.

Title: Surface treatment of ceramic
Inventor: EHATA YOSHIHIRO
IPC: C04B41/51
Filed: 1988-02-25
Abstract: PURPOSE:To inhibit surface oxidation of ceramic whole body and deterioration of a base material and to reduce the cost of equipment by heating both the face to be treated of ceramic and a metallized material inserted between this face and a heating element with Joule's heat due to electrification of the heating element. CONSTITUTION:A metallic material 2 is inserted to the face to be treated of, e.g., prismatic ceramic 1 and the heating elements 3 are brought into contact with it and thereafter a supporting material 4 having insulation and heat insulating effect is placed thereon and pressurized to the direction vertical to the face to be treated of ceramic 1 and fixed. Then the electrodes 5a, 5b connected with an electric source device are fitted to the heating elements 3 and when voltage is impressed between them, Joule's heat is generated on the heating elements 3. As a result, the whole face to be treated of ceramic 1 incorporating the metallized material 2 is heated at high temp. Ceramic 1 and the metallized material 2 are strongly bonded by holding them for about five minutes and thereafter cooling them. Further, since the treated surface layer of ceramic after separating the heating elements 3 is not metallized, it is easily metallized by immersing it in reducing liquid.

IPC: H02K15/08
Filed: 1986-03-03
Abstract: PURPOSE:To prevent a winding in a rotary machine from flying out by providing a penetrating window near the slot of a toothed portion between slots of an armature core and then pressing it. CONSTITUTION:Two sets of windings 3 are inserted through insulation paper 6 to the slot 1 of an armature core 2. A circular penetrating window 4 is formed along the surface near the end of teeth 8 between the slots 1 of a laminated core 2, i.e., near the surface of the slots 2 at the opening side. When an armature of this state is pressed from a direction designated by an arrow P, the window 4 is deformed while the annular right and left ends of the core 2 formed by the window 4 are being projected to the slots 1 side. Thus, a projection (anchor) 7 to prevent windings from flying out, which is bent at the inner periphery, is formed at the opening end of the slot of the teeth 8.

Abstract: PURPOSE:To take a proper step against a trouble generated in a recording medium by setting a bit of discriminating information to each recording medium. CONSTITUTION:To a form to be recorded, a virtual discriminating number is given, and a data is shared among an interface controller (IFC) 52, a print engine (PE) 51 and various additional devices. For instance when maximum axis sheets of paper exist in a laser beam printer system, if the discriminating numbers of at least 1-6 are given, where in the IFC 52, the PE 51, and the additional devices which paper exists can be known. Accordingly, when a jamming is generated, the IFC 52 inquires the discriminating number of a jamming form, of the PE 51, and which data to be re-recorded is can be known exactly. Also, the IFC 52 compares the discriminating number received from the PE 51 at the time point of start of recording with the discriminating number received from the PE 51 at the time point of completion of paper discharge, and can always know the discriminating number of a form in the device, therefore, by specifying jamming paper at the time point of a jamming, an appropriate processing can be taken quickly.
