Title: Formation of continuous pipe on ground
Inventor: MATSUDA SHINICHI
IPC: E03F3/06
Filed: 1983-05-26
Abstract: PURPOSE:To form a continuous pipe having no seam in a desired direction by a method in which materials are continuously sent into the front of a cylindrical space-forming part with a closed front end and an opened rear end, and the cylindrical space-forming part is advanced. CONSTITUTION:When the pressure-sending pump 23 of a working vehicle 16 is driven and materials 90 are sent under pressure into a cylindrical space 31, the materials 90 are melted by a heating element 36, moved backwards while being cooled gradually to solid state, and reaches the rear end of an annular groove 12. When the materials 90 are further sent continuously, the cylindrical space- forming part 30 receives a great propulsion toward the front and is advanced by rewinding slowly a wire 40 from a winch 38, during which period a continuous pipe 91 is formed. The cylindrical space-forming part 30 moves forwards along the ground's surface 42 away from a housing 10 while properly altering its bilateral directions under an adequate external force.

Title: Vehicle behavior control device
Inventor: ARAKI MICHIKI
IPC: B60T8/58
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To increase the boost responsiveness of a brake cylinder on the high pressure side by applying a slight preload in advance to the brake cylinder to be applied with a brake fluid pressure next from the vehicle behavior state, and limiting the application of the slight preload according to the vehicle behavior state during the control of the brake fluid pressure of the brake cylinder. SOLUTION: When zero boost is required for wheel cylinders 2FL, 2RR or 2FR, 2RL, the boost performance coefficient K for turning inner wheels set in response to the wheel cylinder pressure deviation of the turning inner wheels obtained by subtracting the estimated wheel cylinder pressure of the turning inner wheels from the target wheel cylinder pressure of the turning inner wheels is calculated. The turning outer wheel gain is set to 1, and the turning inner wheel gain is set to a value subtracted with the boost performance coefficient K from 1.  The attained wheel cylinder increased/decreased pressure quantity of the turning inner wheels is set to a value much smaller than the target wheel cylinder increased/decreased pressure quantity or to 0 when preload control is applied, and the wheel cylinder boost gradient of the turning outer wheels on the relatively high pressure side is secured.

Title: Filling method of molten metal in vertical die-casting machine
Inventor: NAKASHIMA WAICHIROU
IPC: B22D17/30
Filed: 1978-07-27
Abstract: PURPOSE: To make filling work smoother and stabler by maintaining space while molten metal is moving in a sleeve and pressing the molten metal from the start of filling.  
     CONSTITUTION: Space is maintained between the head M 1  of the molten metal M poured into a sleeve 4 and the top end opening 4a of a sleeve 4. A plunger piston 8 is lowered to lower a counter piston 6 in the state where the space S exists. The counter piston 6 stops when its pressure receiving face 6a becomes flush with the bottom end of the running opening 5 but the descending of the plunger piston 8 is continued and the air between the pressing face 8a and head M 1  is exhausted to the outside through the clearance between the piston 8 and sleeve 4. As a result, the pressing face 8a makes contact to M 1  and the molten metal is pressed and is pressure filled in the cavity through the opening 5 and runner 3. Thereby, the occurrence of freezing, crust, etc. on the circumferential wall part of the sleeve 4 is prevented.

Title: Thermal transfer material
Inventor: TAKIZAWA YOSHIHISA
IPC: B41M5/40
Filed: 1987-04-16
Abstract: PURPOSE:To obtain a thermal transfer material having good preservability and forming a durable transfer recording image, by providing first and second layers on a supporting member and adding unsaturated polyester resin and organic peroxide to one layer while a bridging accelerator to the other layer. CONSTITUTION:First and second thermally fusible layers 13, 14 are provided sequentially on a supporting material 12, where unsaturated polyester resin and organic peroxide are added to one of the first and second layers while a bridging accelerator is added to the other layer. Heat to be produced during recording or fusing/mixing effect between layers cause mixing of unsaturated polyester resin, organic peroxide and bridging accelerator so as to start bridging reaction. Preservability is improved because hardening reaction is not promoted prior to recording. Hardening reaction can be promoted as time elapses after recording or through secondary processing such as heating or pressurizing which is carried out after recording, so as to increase film strength and cohesion of recorded image, thus increasing adhesion to recording medium such as a paper, resulting in improvement of fixedness and durability of recorded image.
