Title: Operation device for pump motor relay for antiskid brake control system
Inventor: TOMIOKA EIICHI
IPC: B60T8/88
Filed: 1991-02-20
Abstract: PURPOSE:To perform reliable operation of the relay of a pump motor even when antiskid brake control is not effected for a long period. CONSTITUTION:A relay signal alpha from a micro computer is brought into a HIGH state at a point of time B for a time DELTAt. When a pump motor relay 1 is normal, the contact thereof is closed for the time DELTAt, and a potential at a point beta between a pump motor M and a pump motor relay 1 is brought into a LOW state or a HIGH state for the time DELTAt. As a result, a trouble detection signal gammais brought into a HIGH state for the same time DELTAt and inputted to a microcomputer. From a fact that the trouble detection signal gamma is brought into a HIGH state for the time DELTAt, it is judged by the computer that the relay 1 is in a normal state. At a point of time D when a time (t) elapses from a point B, a relay check signal alpha is brought into a HIGH state again for the time DELTAt, and thereafter, the above is repeated at intervals of the time (t). This constitution prevents fixing of a contact since the contact of the pump motor relay 1 repeats ON and OFF operation.

Title: Method for welding flat plate made of ultra-heavy steel plate
Inventor: JITSUMATSU YOSHIHIRO
IPC: B23K9/18
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To facilitate groove alignment, not to be required other than local heating and to unnecessitate tack welding by executing arc welding while preheating the vicinities on both sides of the weld zone between flat plates consisting of steel plate having specified thickness, width and length together with the end parts on the opposite side of the weld zone to a specific temperature. SOLUTION: By butt-welding half bottom plates (flat plates) 11, 12 whose thickness T is >=100 mm, width is >=20 times the thickness T and length is >=1.5 times the width, a bottom plate 13 is made. The arc welding is executed while preheating the vicinities on both sides of the weld zone (weld line) 22 of the half bottom plates (flat plates) 11, 12 and the nd parts on the opposite side of the weld zone to 100-150 deg.C with the heaters (heating means) 23-26 for preheating. It is preferable to take the preheating width as 1-3 times the thickness T. As the arc welding, submerged arc welding, MIG welding or TIG welding is used.  By heating the vicinal parts on both sides of the weld zone between the flat plate and the end parts on the opposite side of the weld zone of the flat plate to a specific temperature, the thermal stress by which the camber on the plane on the verge of generating is cancelled.

Title: Rotary vane compressor
Inventor: YASUDA MASAO
IPC: F04C18/344
Filed: 1984-02-14
Abstract: PURPOSE:To prevent the generation of chattering by installing, into a suction passage, check valve for suppressing the counterflow of the working fluid in an operating chamber towards a suction port, thus maintaining the slidable-contact state between a vane and a cam surface in low-speed revolution of a rotor on starting. CONSTITUTION:Since the pressure in a high-pressure chamber 29 is small and a centrifugal force is small on starting, the force for protruding a vane is small. However, a flapper valve 40 is installed into a suction passage 37, and the pressure in an operating chamber 35 opened into the second concaved part 35 is maintained at the lower pressure than that on a suction port 24 side. Therefore, the vane is attracted in the direction of projection by the fluid pressure in the operating chamber 53 under low pressure, and smoothly contacts with a cam surface 41 and moves in slidable ways on the cam surface 41 as a rotor 43 revolves. Therefore, the phenomenon that the vane sharply protrudes during the increase of the revolution speed of the rotor 43 and the vane collids with the cam surface 41 is prevented, and the generation of chattering is prevented, and the abrasion and breakage of the cam surface 41 and the vane are prevented.
