    • A reference pulse signal P is produced which is synchronized in frequency with a pulse signal S derived from a vibration source and has a predetermined duty ratio. Then, a control signal C is produced by providing at least one or more off intervals &agr;, &bgr; . . . at a random timing and random width predetermined for the reference pulse signal P to have the control amplitude correlated with the amplitude of the vibrations at the vibration source. This control signal C is used for controlling the switching action of the electromagnetic valve to have a desired level of pressure change in an air chamber 35 of a pneumatic vibrator which in turn develops a vibrating force on a mass member 20. The vibrations of the mass member can thus offset the vibrations of the chassis of a vehicle. Also, an electromagnetic vibrator can produce a similar control signal for eliminating the vibrations of the chassis.

An air in the oil chutes (15) functions as a sound insulation layer against combustion noises generated in the cylinder bores (2). The air in the oil chutes (15) also serves as a heat insulation layer for a cooling water in the water jacket (8) so that warming up performance of the engine under a cold condition is improved.

    • A hose connecting structure includes a hose whose central and engaging portion having a thermal flexibility resin which is molded by a blow molding method and a mating member which is inserted into the edge opening of the hose. The hose connecting structure further includes a ring-shaped sealing material and a first engaging portion which is disposed in the axial direction by a predetermined distance to the sealing material at either the edge portion of the hose or the mating member and second engaging portion which is directly or indirectly engaged with the first engaging portion at either the edge portion of the hose or the mating member. The central and the engaging portion of the hose connecting structure includes a thermal flexibility resin which is molded by a blow molding method. Therefore, the most suitable soft and hard resin for the appropriate portion can be used. When the engaging portion with the mating member and the central portion are molded integrally, the working efficiency is improved. The sealing material such as an O-ring is used for the engaging surface. Therefore soft resin is not used for the engaging surface, and a free selection of resin is achieved. Moreover, the polishing of the engaging surface is not required.

    • The present invention is directed to an anti-skid control system which includes a return passage provided for communicating a wheel brake cylinder with an actuator. A pressure pump is disposed in the return passage, and a reservoir is disposed in the return passage at the inlet port's side of the pump. The reservoir stores the brake fluid in the wheel brake cylinder through the actuator to decrease the wheel cylinder pressure. The pump discharges the brake fluid stored in the reservoir into the return passage thereby to gradually increase the wheel cylinder pressure. The amount of brake fluid stored in the reservoir is estimated on the basis of the amount of brake fluid fed into the reservoir and the amount of brake fluid discharged therefrom. The amount of brake fluid fed into the reservoir is estimated on the basis of the wheel cylinder pressure provided when the pressure decreasing operation starts, and in response to the pressure decreasing time. The amount of brake fluid discharged from the reservoir is estimated on the basis of the wheel cylinder pressure set when the gradual pressure increasing operation starts, and in response to the gradual pressure increasing time.
