Title: System for detecting name of town under power failure
Inventor: KUNIEDA TOSHIHITO
IPC: G01R31/08
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To enable the detection of names of a towns under a power failure without being based on accident information from a control office. SOLUTION: Each monitoring slave station 10 is placed at a location provided with a pole mounted transformer of a distribution line L1, and a communication line C2 is arranged between the monitoring stations 10 and a monitoring master station 23 along the communication line L1. The monitoring slave station 10 detects the presence or absence of the voltage of the pole mounted transformer Tr and transmits a communication signal according to the state of change in the presence or absence of the voltage and an identification sign set for the monitoring slave station 10 in advance to the monitoring master station 23 via the communication line C2.  The monitoring master station 23 receives the communication signal and the identification sign transmitted from the monitoring slave station 10 by communication and displays the name of a town with a power failure of the distribution line L1 and the state of the distribution line L1 (a state of power failure or a state of power restoration).

Title: Resistance welding equipment
Inventor: KISHI YUUZOU
IPC: B23K11/31
Filed: 1979-07-05
Abstract: PURPOSE: To provide equipment which is safe, is compact and is superior in durability by letting  a pressing cylinder serve also as an electric power feed cylinder and omitting a cord cable tube for  connecting a movable rod.  
     CONSTITUTION: The weld zone of given metals 37 is set between electrodes 11, 36 and hydraulic  working fluid is fed through a feed port 18. When the oil is discharged from a feed port 19, the  pressure acting upon a pressing chamber 24 forces a piston 22 which in turn force-advances a rod  21 by way of a belleville spring 28 and a current collecting plate 30, causing the electrode 36 to  sandwich the works 37 under pressure integrally with a current supply shank 35 together with the  electrode 11. When pressed further, the piston 22 force-advances opposedly to the rod 21, causing  the tapered face of a pressure ring 27 to push a current collecting ring 32 against the belleville  spring 28. Then, the respective split bodies of the current collecting ring 32 are bulged and  expanded to open outward by the pressure sandwiching of the current collecting plate 30 and the  pressure ring 27, by which they are contacted with an electric power feed liner 20. Hence, the  cathode current from an electric power feed cable 17 reaches the cathode electrode 36, and in the  meantime, the anode current is supplied from an arm 12 to the anode electrode 11 and is supplied  to the metal works 37, whereby the resistance welding is accomplished under pressure.

Abstract: PURPOSE:To effectively utilize cold held in liquid nitrogen, in a freezing processing technique wherein liquid nitrogen is used. CONSTITUTION:In order to freeze an object to be freezed in a processing chamber 4 using cold held in liquid nitrogen by spraying the liquid nitrogen into the precessing chamber 4, blowoff ports 9 for blowing off liquid carbon dioxide or carbon dioxide gas are formed opposite to exhaust ports 6 for exhausting vaporized nitrogen gas from within the chamber 4, respectively. Liquid carbon dioxide or carbon dioxide gas is blown off from the blowoff ports 9 to effect heat exchange between cold held in vaporized gas of the liquid nitrogen and the carbon dioxide blown off, thereby forming dry ice. The dry ice thus formed also is used to cool the object to be freezed.

Abstract: PURPOSE:To reduce an abrasion quantity and a fatigue of movable parts, and also to select a cartridge within a desired selection time by determining an acceleration and a moving speed of each moving mechanism in accordance with a time interval of a cartridge selecting request or a moving distance. CONSTITUTION:In accordance with a time interval of a cartridge selecting request or a moving distance, a moving speed of an accessor 16 is decreased by using a specified expression, when a selecting request to a cartridge selecting device is low. On the other hand, when the selecting request to the cartridge selecting device is high, the moving speed of the accessor is increased, a selection time of a cartridge 2 is shortened, and a selecting request processing capacity of the cartridge selecting device per unit time is raised. Or when a distance between a target cartridge and a picker mechanism 3 at the time of a selecting request is short, the moving speed of the accessor is decreased. On the other hand, when the moving distance is long, said speed is increased. In this way, the processing capacity of the cartridge selecting device is not reduced, and an abrasion quantity and a fatigue of movable parts can be reduced. Accordingly, a periodical inspection and a maintenance interval for securing the reliability can be extended, therefore, operation and maintenance costs can be reduced.
