Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To perform the excellent welding by detecting the welding current and the voltage between tips, and performing the simulation of a weld zone by the heat transfer calculation to presume the condition of generation of a nugget. SOLUTION: Welding electrodes 8, 8 perform the resistance welding of works 11, 11 to be welded. A signal processing part 2 receives the data on the welding curtent and the welding voltage. A permeability change detection part 3 monitors the change in the impedance (the ratio of the voltage to the current), and checks that the temperature of the work 11 to be welded rises over the magnetic transformation temperature. The material constant such as the fringing coefficient taking into consideration the specific resistance and the flowing way of the current is determined by a heat transfer simulator 4. The simulator 4 prepares the differential equation using the material constant, receives the data on the current and the voltage, and calculates the current density and the current-carrying diameter. The equation of temperature is solved to calculate the temperature distribution, and the region over the melting temperature is defined as the nugget. A comparison part 5 controls the welding condition based on the condition of the nugget.

IPC: G11B17/04
Filed: 1983-12-28
Abstract: PURPOSE:To improve feeding performance by providing a means which energizes the carriage connected to a pick-up arm in the reset position direction at any time, a friction roller which contacts with the carriage with pressure and carrier-drives it, and an attaching/dataching means which makes the roller separate or contact with pressure for the carriage. CONSTITUTION:When a jacket 71 is inserted to a player in a state that a pick- up arm 57, that is, a carriage 56 is at the reset position, the jacket 71 advances along a guide rail 59, and it advances while it turns and pushes down an attaching/detaching roller 68. Therefore, a friction roller 67 separates from the bottom surface of the carriage 56, but the carriage 56 does not move because it is at the reset position. When a disk 72 is accompanied in the inside of the player and the empty jacket 71 is removed, at the same time, the friction roller 67 is contacted with the bottom surface of the carriage 56 together with rotation of the disk 72. At the same time, a driving motor 62 rotates, transmission is executed to the friction roller 67, and the reproducing state is obtained by moving the carriage 56, that is, the arm 57. At this time, the friction roller rotates in A direction, and the carriage 56 is transported in B direction.

Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To attach a wiper blade irrelevant to the types of a right- and left- hand-automobile by constituting both suspension plates of a holder in such a state as providing pin insertion holes and small projections in lines laterally in target positions, by setting either one of the suspension plate to a yoke face attaching piece, and setting the other to a suspension plate attaching piece of the holder. SOLUTION: A plate is bent perpendicularly, one bending piece is set to a yoke attaching piece 7A of a wiper blade, and the other is set to a holder attaching piece 7C. When the positional direction of the holder attaching piece 7C of the holder 7 is inverted so as to position the holder attaching piece 7C of the holder 7 to the left side of the yoke 3 or to the right side in attaching the holder 7 to the yoke 3, this constitution only changes the positional direction of the connector attaching piece 7C of the holder 7 in the target position side in the opposite side of the yoke 3. The yoke attaching piece 7A is thus inverted vertically but not inverted its front/back. The wiper blade of the same kind is thus attached to an either case of the right- or left-hand-drive automobile.

Title: Method and device for controlling main steam temperature of boiler
Inventor: SUGANO AKIRA
IPC: F22G5/12
Filed: 1991-09-30
Abstract: PURPOSE:To improve the following property of control by a method wherein integrating process is stopped when the load of a boiler is changed with a changing rate higher than the set value of main steam temperature of the boiler. CONSTITUTION:A main steam temperature is controlled so as to be an objective value by a method wherein the amount of spray water poured into superheated steam is controlled based on a control amount obtained by effecting proportional integrating process of a difference DELTAT1 between the set value T1* of the main steam temperature of a boiler and a main steam temperature feedback value T1, detected by a main steam temperature sensor, by a proportional integration control means 105. When the load of the boiler is changed with a changing rate higher than the set value T1* of main steam temperature, the integrating process effected by the proportional integration control means 105 is stopped. As a result, the returning operation of integration after finishing the change of the load is eliminated and, therefore, the response of a superheater spray valve 110 with respect to the fluctuation of the main steam temperature after finishing the change of the load is quickened. According to this method, the following property of control can be improved.
