Filed: 1982-10-27
Abstract: PURPOSE:To provide a multistage fluid pressure cylinder of compact size with a cushion having a short mounting dimention by disposing a throttle flow path capable of connecting the interior of a cushion hole with a forward stroke side fluid chamber with a small flow rate. CONSTITUTION:When a movable cylinder 13 makes a forward stroke, communicating holes 19a, 19b, 19c are fitted sequentially in order from a larger size one rito a rod cover 12a blocked up, so that a discharge flow path of a backward stroke side fluid chamber 21 is throttled to produce a cushion effect. When a piston 10 makes backward stroke to fit a cushion boss 26 to a cushion hole 27, a discharge path is throttled by a hole 26c so that a fluid in the cushion hole 27 produces a cushion effect. The measure of a cushion capacity formed by the cushion boss 26 and the cushion hole 27 may be same as the cushion capacity on the rod end side of the movable cylinder 13. Accordingly, the outside diameter of the cushion boss 26 can be small enough in comparison with the outside diameter of the piston 10, resulting in that an increase in length of a head cover 9d and a tube 9a is minimized.

Title: Vehicle brake control device
Inventor: ARAKI MICHIKI
IPC: B60T8/26
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle brake control device which can surely stop a vehicle while reducing rocking-back behavior just before the vehicle stops. SOLUTION: A wheel speed sensor 24 is provided and vehicle speed is computed on the basis of detection outputs of the sensor 24. When the vehicle speed is not greater than a certain speed and detection is made that the vehicle is about to stop, loads applied to front and rear wheels are computed on the basis of detection outputs of an acceleration sensor 23 and the wheel cylinder pressure of the rear wheels is increased according to the computation result so as to increase the proportion of braking forces allocated to the rear wheels. As a result, braking forces on the front wheels are weakened and pitching behavior is reduced so as to reduce rocking-back behavior.  The total of the braking forces applied to the front and rear wheels after the ratio of the braking forces allocated to the front wheels versus the rear wheels is varied is about the same as it is before the ratio is varied, so that the vehicle can be surely stopped.

Abstract: PURPOSE:To make it possible to suppress the scattering of broken pieces in an explosion to the minimum by installing insulating bands which consist of a high polymer material of a resin, a rubber, or the like, in the contacting condition to the outer peripheries of the trunks of an insulator tube main body. CONSTITUTION:Insulating bands 4 which consist of a high polymer material are installed in the contacting condition at the peripheries of trunks 3 which are straight parts between umbrellas 2 and 2 of an insulator tube main body 1. As a result, the insulating bands 4 are installed in the closely contacting condition at the peripheral surfaces of the trunks 3 where the thickness is the smallest in the insulator tube main body 1 and the stress in the breaking is liable to concentrate. Consequently, even when the pressure inside the insulator tube rises abnormally for some cause and the insulator tube main body 1 is exploded, the insulating bands 4 of the high polymer material with an excellent elasticity absorb the energy of explosion, suppress the scattering of broken pieces to the minimum, and the danger to a human body, a damage to the peripheral apparatuses, and the like can be prevented.
