Title: Stand device for welding
Inventor: MOTOKAWA YASUJI
IPC: B23K37/00
Filed: 1978-08-16
Abstract: PURPOSE: To prevent overturn of the stand with small tensile force by controlling the stretching force of the rope wound to a winch for tilting the stand by means of a piston cylinder.  
     CONSTITUTION: Where the tension of a rope 6 is low as a spring 10 has elongated, a limit switch 24 opens a solenoid valve 19 to supply pressure oil to a piston 17 and put the rope 6 in a tense state. During this time, the spring 10 is compressed and protrusions 28, 29 move. When a limit switch 25 is operated, the solenoid valve 19 is closed and the pressure state of the piston 17 is maintained. Thereby, the tense state of the rope 6 is corresponded to the compression state of the spring 10. The solenoid valve 22 is controlled by limit switches 26, 27 to release the pressure in the chamber of the piston 17 when excess tension is produced in the rope 6 thereby returning the rope to the desirable tense state. As a result, the tilting state of the stand 2 is stabilized and circumferential welding or the like is normally accomplished.

Abstract: PURPOSE:To prevent a detect of reliability such as an aluminum migration by a defective coverage of a sputtering operation by a method wherein a distance between a stepped part of a field oxide film and a contact hole is made sufficient in an extraction direction of an aluminum wiring part. CONSTITUTION:In a semiconductor device, a contact hole 14 is provided inside a region of a stepped part 15 of an insulating film, and a metal wiring part 11 with which the contact hole 14 is covered is formed by a sputtering method. In this semiconductor device, a distance A between the stepped part 15 of the field oxide film and the contact hole 14 is made sufficient only in an extraction direction of an aluminum wiring part in such a way that an aluminum sputtered film 11 can be covered satisfactorily. That is to say, the distance between the contact hole 14 and the stepped part 15 of the field oxide film in the extraction direction of the aluminum wiring part is set to the size A; the contact hole 14 of the aluminum silicon film 11 is covered satisfactorily in a part where an electric current flows; a size B is prescribed by a mask alignment accuracy in other directions; its size is reduced from the A to the B. Thereby, it is possible to prevent a defect of reliability such as a migration or the like, and to reduce an element.

Title: Storage battery
Inventor: WADA YASUO
IPC: H01M50/571
Filed: 1987-04-22
Abstract: PURPOSE:To prevent the leakage of an electrolyte even if the electrolyte creeps along an electrode post by installing a cover formed by injection-molding a synthetic resin to a post having an elastic gasket so as to enclose the gasket. CONSTITUTION:A cover 2 is formed by injection-molding a synthetic resin to an electrode post 1 having an elastic gasket 6 so as to enclose the gasket 6. Since the radius of the inner diameter of the gasket 6 is smaller than the radius of the outer circumference of the electrode post 1, the internal stress of the gasket 6 is applied to the post 1 in a vertical direction as compressive stress and to the gasket 6 in a circumference direction as tensile stress. When the cover 2 is formed by injection-molding a synthetic resin, the gasket 6 is pressed against the post 1 by the pressure of injection molding to form good sealing capability. The contact of the electrode post 1 with the cover 2 is made close, and the leakage of electrolyte creeping along the electrode post 1 can be prevented.

Abstract: PURPOSE:To automatically load a base plate with a simple mechanism by enabling a stopper supporting the lower end of a base plate to be taken out and introduced for the base plate supporting face of a reversing table in a process wherein the base plate is contrarotated with the reversing table and provided to an auxiliary electrode frame. CONSTITUTION:A base plate 1 is placed on the base plate supporting face 2a of a reversing table 2 in a horizontal state and the stopper 3 fitted to the table 2 is projected on the face 2a with a cylinder 4 and the lower end of the base plate 1 is allowed to abut thereon. In this state, the table 2 is rotated at about 90 deg. with a cylinder 5 around an axis 6a in the direction A and the base plate 1 is regulated to a vertical state and made adjacent to the inside of an auxiliary electrode frame 20 in the case of plating and the lower end of the base plate is fitted to plural groove members 24 on the lower frame part 23 of the frame 20 and the base plate is set to a jig. In this case, the base plate 1 is supported with a back receiving bracket 9 which is progressed in the direction B and furthermore the upper end of the base plate 1 is clamped with a mechanism 10. When the table 2 is returned to the original position, the stopper 3 is pulled to the inside of the face 2a. Thereby the stopper 3 does not interface with the base plate 1 and the frame 20, etc.

Title: Electrically fused coupling
Inventor: SATO AKIHIKO
IPC: B29C65/34
Filed: 1992-04-20
Abstract: PURPOSE:To connect a pipe without carrying out marking work by tentatively fitting a core member engagement part with the inner peripheral edge of a coupling edge part by a large holding force by the force for fitting a core member to a transparent or semitransparent resin pipe and coloring the core member to a color permitting the discrimination from the resin pipe. CONSTITUTION:In the state where a core member 4 is fitted in a resin pipe 2, the engagement part 41 of the core member 41 is projected from the outer peripheral edge at the edge part of the resin pipe 2, and engaged with a stopper 32 when fitted with a coupling body 3. In this state, the length L of the core member 4 is shortened in comparison with the distance D from the edge part of the coupling body 3 to the stopper 32, so that the core member 4 is accommodated into the coupling body 3. Further, the core member 4 is colored to the color permitting the discrimination from the force transparent or semitransparent color resin pipe 2. The holding force of the core member 4 and the coupling body 3 is made larger than the fitting force to the resin pipe 2 of the core member 4, and the tentative fitting is prevented from being released. Since the fitted state can be grasped by the core member 4 which can be seen through the resin pipe 2, the resin pipe 2 can be connected without carrying out the marking work.

IPC: G01N33/28
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To continuously and simply evaluate the influence of a thermal history in a metal working operation by a method wherein a water-containing metal working oil which is circulated inside an apparatus is spouted from a spouting nozzle so as to come into contact with a metal object to be worked and the water-containing metal working oil is degraded. SOLUTION: An underwater oil drop-type emulsion is put into an emulsion bath 12. The bath 12 and a spoutinh nozzle 9 are connected by a pipe, a bypass valve 8 is installed at a pipe which is branched from the intermediate part of the pipe, and its tip is connected to the bath 12. The emulsion is passed through a solenoid valve 7 and the bypass valve 8 by a magnet gear pump 4, and it is returned to the bath 12 so as to be circulated. When the gear pump 4 is operated, the emulsion is passed through a solenoid valve 6 and it is spouted, from the spouting nozzle 9, at a wide angle to a metal working part 10 which is heated at a test temperature. The emulsion which is brought into contact with the metal working part 10 is subjected to a thermal history, and it is returned to the bath 12 through the pipe.  Since the metal working part 10 is brought into contact with the emulsion so as to lower its temperature, it is heated by a heater 11.

The data protection elements - encryption keys, encryption algorithms, and encryption obfuscation - are generated or selected, respectively, at a new instance of communication across the network and no data protection elements are transmitted across the network. The artificial neural network is trained on a blockchain with the addition of each new block to the blockchain and is used to generate a finite set of encryption keys at each node simultaneously. Such encryption keys, encryption algorithms and encryption obfuscation are associated with the neural network on each node and are then used for decryption of the transmitted data.
