Title: Pulse arc welding method
Inventor: GOTOU KENJIYU
IPC: B23K9/06
Filed: 1978-12-08
Abstract: PURPOSE: To achieve the improvement in starting characteristics and prevent the occurrence of crater cracking by making base current characteristics into constant-voltage only at the arc starting and turning OFF the pulse currents and switching the base current to constant-voltage characteristics in the specified time till the ending of welding in pulse arc welding.  
     CONSTITUTION: In the pulse arc welding machine provided with a pulse current generating part and an auxiliary power source 2, the output characteristics of the auxiliary power source 2 are made into constant-voltage characteristics at the welding start. The starting current equivalent to that of the power source for constant-voltage MIG welding is obtained for the arc starting, whereby the difficulty in the starting characteristics in the MIG pulse arc welding may be eliminated. At this time the supply of the pulse currents from the pulse current generating part 1 is not  necessary. The tap of the transformer 2a of the auxiliary power source 2 is changed over to the  high voltage side after the arc starting, by which the stable base current is supplied and the pulse  currents are periodically supplied and are superposed on the base current. Upon ending of the  welding, the pulse currents are cut off and the tap of the transformer 2a is changed over to the  low voltage side and at the same time the characteristics of the auxiliary power source 2 are made  into constant-voltage characteristics, whereby the occurrence of crater is perfectly prevented.

Title: Solenoid valve
Inventor: KASAI NOBURU
IPC: F16K31/06
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce impact pressure at the time of opening and closing a valve. SOLUTION: In a solenoid valve, a main valve 18 is opened due to pressure difference between coolant inside a chamber 22 and the coolant on an upstream side of a fluid passage, and due to the pressure difference between the coolant inside the chamber 22 and the coolant on the downstream side of the fluid passage which are generated by opening a pilot valve 26. In such a solenoid valve, the main valve 18 is lifted by specified rate from a full close position of a valve seat port 16 to an initial motion completion position near the full close position composed to a full open position of the valve seat port 16. During that time, a small flow amount setting valve part 40 arranged on the main valve 18 having a diameter smaller than an aperture of the valve seat port 16 is located inside the valve seat port 16.  A flow amount between the upstream side and the downstream side of the fluid passage is regulated to be a small amount which is determined by a sectional area of a circular clearance formed between the valve seat port 16 and the small flow amount setting valve part 40, during the time that the main valve 18 is shifted from the full close position to an initial motion completion position.

Title: Method and system for searching optimum transfer group
Inventor: KATO MASAMI
IPC: G08G1/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To save wasteful group searching and to process group searching in a short time by previously limiting a searching area from a start place and a destination. SOLUTION: Time range of route searching is limited from the start place O0 and the destination D0 . A straight line connecting the start place O0 and the destination D0 is set to be a base line, it is extended in the extending direction of the base line by (x) and a rectangle obtained by extending it in a vertical direction by (y) is set to be the range of searching as a simple method for limiting the area. Transfer nodes 1 and 3 become the objective nodes of searching since they are within the route searching area. Since transfer nodes 2 and 4 are out of the area, they become the nodes out of the object of searching. Then, all links connected to the transfer noes 2 and 4 become out of the object of group searching. When the long form of the Japanese archipelago is considered, the almost optimum solution can be obtained from the range if y=150 km and x=100 km are set. Thus, processing time depends on the position relation of the start place G0 and the destination D0 but it can be suppressed to not more than one of several quantity of former time.

Title: High-pressure gas container with double safety device
Inventor: OZAKI HIROTSUGU
IPC: F17C13/12
Filed: 1985-07-13
Abstract: PURPOSE:To prevent a container from being moved via a reaction force applied against the gas outflow by sealing an opening section with a safety sealing plate and arranging a filter restricting the passing gas quantity at a position on this side of the safety sealing plate. CONSTITUTION:A safety sealing plate 1 is welded on the end face of the opening section 4 of a main body 3 to seal the opening section 4.
