Title: Auxiliary guide apparatus of balance weight for elevator
Inventor: YAMAMOTO TAKEKI
IPC: B66B11/00
Filed: 1987-09-14
Abstract: PURPOSE: To easily mount an auxiliary guide device in an integral member by forming the auxiliary guide device of a balance weight into the shape of L, and making the standing size of its side mounted on the side face part of a hanging frame smaller than the interval between the side face of the hanging frame and a guide rail. CONSTITUTION: An auxiliary guide device 4 is mounted on the side face part 1a of a balance-weight hanging frame and guided at an interval to a guide rail 5. The auxiliary guide device 4 has an L-shape and the standing size A of its side mounted on the side face part 1a is smaller than the size C of the interval between the side face part 1a and the guide rail 5, with the horizontal part of the L-shape formed with a cut having an interval X to the guide rail 5. During insertion, the auxiliary guide device 4 is easily inserted into the interval C between the side face part 1a and the guide rail 5 with the side of the rising size A facing down. Next, the auxiliary guide device 4 is rotated 90 deg. and its A-size face is bolted to the side face part 1a.  In this case, the 90 deg. rotation of the horizontal part does not bring the horizontal part into contact with the guide rail 5 because of the cut. Therefore, even integral members can easily be mounted.

Title: Low pressure electronic hydraulic type governor
Inventor: MATSUO NAOKI
IPC: F01D21/14
Filed: 1985-10-16
Abstract: PURPOSE:To make possible to continue the operation of a turbine without tripping the latter, by providing such an arrangement that operation is automatically changed over form a normal servo-valve to an auxiliary servo-valve when the normal servo-valve sticks. CONSTITUTION:During normal operation a digital control board 7 processes a signal from a speed detector 6 to regulate the opening degree of a normal servo-valve 13, and therefore, control oil is fed through a solenoid changeover valve 15 and a servo-valve 13 to an actuator 18 in which a piston is therefore moved in valve opening and closing directions. Therefore, the supply of the control oil for a servo-motor 17 is regulated so that the opening degree of an adjusting valve is controlled. Further, if the servo-valve sticks due to scale or the like in the oil, the digital control board 7 delivers a signal to the solenoid changeover valve 15 which therefore changeovers its ports to shut off the control oil for the servo-valve 13 but to feed the control oil to an auxiliary servo-valve 14. Such a changeover is indicated by means of a lamp 18L.

Title: Method for preventing indentation flaws of cr system stainless steel
Inventor: TANIGUCHI KAZUHIRO
IPC: B21C47/34
Filed: 1994-08-30
Abstract: PURPOSE: To reduce indentation flaws by jetting a high pressure water between the side guide and a work roll on the entrance side of a rolling mill and removing welded objects stuck to the surface of a rolling stock. CONSTITUTION: A rolling stock 2 is advanced while it is positioned by a side guide 4, and rolled by a work roll 3. A high pressure water is jetted from a nozzle 6 and directed to the rolling stock 2 between the side guide 4 and the work roll 3.
