Title: Control booster
Inventor: TAKAYAMA TOSHIO
IPC: B60T13/52
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a control booster properly detecting a pedal operation brake activation during automatic braking. SOLUTION: A stop key 29 travels from a state where the stop key 29 is on a rear side contact surface 81a side (a state where a reaction force from a switch 67 applied on a switch operation rod 73 matches a spring force of a spring 80 for the switch) to an intermediate position state. When the stop key 29 is on the rear side contact surface 81a, only a returning force of the spring 80 is applied on a contact operator 69 of the switch 67. When the stop key 29 is moving to the intermediate position state, a contact part 72 separates from the contact operator 69 (the switch operation rod 73 moves toward a separating direction relative to the switch 67), and no load is applied on a contact operator 69. Thus, when a brake pedal is stepped during automatic braking, a breakage of the switch 67 is avoided, and the pedal operation is detected by an open state of the switch 67.

Title: Method of manufacturing hot-rolled steel plate
Inventor: ARAYA SHOICHI
IPC: B21D22/20
Filed: 2000-04-05
Abstract: PROBLEM TO BE SOLVED: To efficiently remove scale even when a hot-rolled steel plate is not threaded through a pickling line and to impart self-lubricity to the steel plate itself when removing oxidized scale on the surface of the hot-rolled steel plate. SOLUTION: In a line where the steel plate is hot-rolled by joining the tail end part of a preceding rolled stock and the tip part of the succeeding rolled stock between rough rolling equipment and finish rolling equipment, by threading the plate in a reducing atmosphere between the final finishing mill and a pinch roll, the oxidized scale on the surface of the steel plate is removed by reduction. It is preferable to cool and/or anneal the steel plate during threading in a non- oxidizing atmosphere and to apply a lubricant to the steel plate right before coiling. Then, because the scale is removed without in-line performing pickling treatment, a pickling line is unnecessitated and waste acid treatment is unnecessitated besides process omission. By imparting lubricity to the steel plate itself, the lubricant is unnecessitated in plastic working after completing rolling.
