Title: Continuous casting method
Inventor: YANAGI HIDEKI
IPC: B22D11/128
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a producing method for a continuous cast slab which can sufficiently secure the necessary quality even in the case of applying a rolling at small rolling reduction ratio (= cast slab thickness/product plate thickness) without reheating. SOLUTION: The rolling reduction having 2 to <15mm/sec rolling reduction velocity and 0.1 to <0.5 rolling reduction ratio is applied till the completion of solidification by using a surface member in the unsolidified range of 65-97% solidified ratio of the cast slab. By this method, the continuous cast slab fining the structure at the center part thereof without center porosity is produced and also, a steel plate having the necessary quality can be produced by using this cast slab as hot rolling base stock under condition of rolling at the small rolling reduction ratio without reheating.

Title: Thermal fusing method
IPC: B31B50/64
Filed: 1991-08-21
Abstract: PURPOSE:To enable thermal fusion to be effected with good bonding strength by subjecting a polyolefin part to a flame treatment and a hot-air treatment, and also subjecting a polyester part only to a hot-air treatment, and then by press-bonding both the surfaces to be thermally fused each other. CONSTITUTION:A laminate film having a polyester surface 2 corresponding to a vessel inner surface and a polyolefin surface 3 corresponding to a vessel outer surface in its rear surface and a polyester surface 2 in its one end part 4 is subjected to a flame treatment in a polyolefin part of the end part 4 by means of a gas burner 5. In the next place, it is subjected to a hot-air treatment by means of a hot-air treating nozzle 6. At that time, the polyester part of the end part 4 is hot-air treated at the same time. Meanwhile, the other end part of the polyester surface is hot-air treated by means of the hot-air treating nozzle 6. After the treatment like this, the outer surface and the other one end of the polyester surface hot-air treated are joined each other to thus be thermally fused through press joint.

Title: Contactor control method
Inventor: SHIRASU KAZUO
IPC: B60L3/04
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To easily dissolve a current carrying failure between a fixed contact and a plunger type movable contact by putting both contacts in an 'off' state, and then putting both contacts in an 'on' state to repeat action in the case of failing to detect constant voltage between both contacts in the 'on' state of both contacts. SOLUTION: A field winding W of contactors MF, MR is excited by sending an 'on' command to make a movable contact 2 abut on a fixed contact 1 to thereby put both contacts 1, 2 in the 'on' state, and whether constant voltage is applied to carry a current between both contacts 1, 2 is detected. In the case of not detecting constant voltage, it is judged as a current carrying failure, and an 'off' command is sent to once terminate exciting of the field winding W. The 'on' command is then sent to excite the field winding W to thereby put both contacts 1, 2 in the 'on' state. With this constitution, insulating material such as dust and an oxide film stuck to a contact surface can be easily removed by impact force generated in projecting and retreating the movable contact 2 to abut on the fixed contact 1.

Since the core 9 of secondary coil 2 mounted on a running vehicle 3 is disposed between pole plates 7, 8 and decreases the magnetic resistance therebetween, he lines of magnetic force are concentrated thereat. The lines of magnetic force interlink with the winding 12 of the secondary coil 2 to induce a current therein. Since the magnetic resistance between the core 9 of the secondary coil 2 and the core 4 of the primary coil 1, at the opposite ends thereof, varies slightly upon lateral shift of the secondary coil 2, magnetic coupling between primary and secondary coils does not weakened abruptly and the power transmission efficiency from the primary coil to the secondary coil 2 is kept constant.

Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a solar unit through a simple structure by support the back face of a support plate using a movable support mechanism and positioning the support plate and a solar unit fixed thereto at a specified angle. SOLUTION: A sleeve 3a screwed over a feed rod 3b moves in the axial direction within the range of the length of the feed rod 3b as the feed rod 3b telescopes in the lengthwise direction to vary the angle of a support post 2d connected through a connecting part 2f by an amount corresponding to the backward and forward moving motion. Consequently, the angle of a support plate 2a secured perpendicularly to the support post 2d and a solar unit 1 secured horizontally to the support plate 2a is varied in accordance with the movement of a circular pivot supporter 2b. An excellent tracking solar unit can thereby be realized by previously adapting the displacement of the light receiving surface to track the solar light optimally.
