Title: Brake device
Inventor: ONUMA YUTAKA
IPC: B60T13/66
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To prohibit the useless operation of a brake operation force booster during the stoppage of a vehicle, and prevent the occurrence of an operation noise by applying the constitution that a condition for the operation start of the booster and another condition for timing with no reference time elapsed from the start of a vehicle operation, when concurrently established, are made harder than the case of non-concurrent establishment. SOLUTION: When a vehicle is identified as shifted from a stop state to a travel state, the determination of reference master cylinder fluid pressure on the basis of an output signal from a booster vacuum switch 164 is permitted, even before the elapse of the preset time, and a pump 40 is thereby made to easily start an operation. In other words, when the first condition as a time before the elapse of the preset time, and the second condition as the vehicle in a stop state are concurrently established, decision is made to increase the reference master cylinder fluid pressure more than the case of the non- concurrent establishment of the two conditions, thereby making difficult the start of the pump 40. As a result, the occurrence of a operation noise is prevented at the start of the vehicle and tranquility is improved.

Filed: 1989-03-17
Abstract: PURPOSE:To press a broad strip member and a soft material strip member to the outer circumferential surface of a reel uniformly as well as to wind the tip part on the surface without entailing any damage to it by installing a clamp arm at the outside in the circumferential direction of the reel, and setting up a pinch roller at this arm tip in the reel free of contact and separation. CONSTITUTION:A tip part of a strip member 10 is made to go along a reel side part in a state of separating a pinch roller 7 from a reel 1. In this state, a clamp arm is rotated by a clamp driving mechanism with a mounting shaft 6a to a whirling arm as the center, and the strip member is pressed to a reel outer circumferential surface with a pinch roller 9 at this arm tip. Afterward, the reel is rotated while the whirling arm is rotated at the same speed by a turning drive mechanism, and the whole strip member pressed by the pinch roller is turned round. Next, rotation of this whirling arm is stopped at a position just before the strip member is wound in pile and then only the reel is rotated. With this rotation, the tip part of the strip member is wound several times on the reel. Afterward, the pinch roller is separated from the reel.
