Title: False speed generating device for anti-skid control device
Inventor: MATSUDA TOSHIRO
IPC: B60T8/66
Filed: 1989-05-19
Abstract: PURPOSE:To perform accurate anti-skid control by computing the false speed from the wheel speed detection value of driven wheels during non-braking, and comparing the wheel speed detection values of the driven and driving wheels with the false speed at the initial time of braking so as to set a decelerating grade. CONSTITUTION:At the time of non-braking, a false speed generating device 27 generates the false speed uninfluenced by the wheel spin of driving wheels 3, 4 on the basis of the wheel speed detection value of driven wheels 1, 2 detected by wheel speed detecting means 26a, 26b. At the time of braking, however, the wheel speed detection values of the driven wheels 1, 2 and the driving wheels 3, 4 are compared with the false speed, and in case the false speed is intermediate between the wheel speed detection values of the driven wheels 1, 2 and the driving wheels 3, 4, the false speed is decelerated with a relatively small decelerating grade and with a large decelerating grade when the false speed is larger than both wheel speed detection values, thus generating the false speed corresponding to the actual speed. The target wheel speed is then set by target wheel speed generating circuits 28a-28c. Accurate anti-skid control can be thus performed.

Filed: 1987-05-25
Abstract: PURPOSE:To make a tank have a structure which is free from defects in intensity, while minimizing the whole structure of its device and obtain a insulating- gas-filled transformer having the high safety for an internal tension and also having a long lifetime for cyclic operations by causing board thickness reinforcing parts of protruding parts for securing insulating distances as well as an outgoing opening part for taking out leads to be integrated in one or by making each reinforcing part serve a double purpose. CONSTITUTION:Protruding parts 14 of a tank 1 having cross sections of semicircle forms and also having each distance of a constant value from a winding end part 5a are formed at positions facing end parts 5a of a high tension winding 5. An outgoing opening 15 for taking out leads is mounted at a top part of the protruding parts 14. Then, there is a structure where board thickness reinforcing parts 16 of the protruding parts 14 themselves share the board thickness reinforcing part of the opening 15. Thus, a simple structure which allows the reinforcing parts of both the protruding parts and the outgoing opening to be integrated into one improves the intensity of the tank and makes the safety for internal tension high and also a lifetime for cyclic operations long.

Abstract: PURPOSE:To provide a correction mechanism which can perform the stable right-left positioning and the tilt correction of forms by controlling these operations to prevent the jam, breakage, etc., of a form that has been conveyed with a large tilt. CONSTITUTION:A form 3 is conveyed to the positions of sensors 12 and 13, and the tilt amount of the form 3 is measured. If the form 3 tilts in the direction where the side of the form 3 opposite to its reference face 10 travels first with a tilt amount larger than a set value, the revolutions of drive rollers are stopped. Then, the drive rollers are revolved in the direction opposite to the conveying direction of the form 3, and the form 3 is bent between the drive rollers so that the tip of the form 3 touches the drive rollers and a pressure roller 18b. Thus, the tilt of the form 3 is corrected. Then, the drive rollers are revolved forward to bite the form 3 and a pressure roller 18a is lifted together with an oblique roller 9 pressed to a conveying surface. The roller 18b is lifted and the press contact states of both rollers 18a and 18b are canceled for correction of the skew of the form 3. Thus, the form 3 is conveyed.
