Abstract: Filter has a filter main body, a container, a first counter room, and a second counter room. A counter air is introduced into the first counter room through the counter air discharge valve, and fine particles trapped in the filter main body are removed and transported to the second counter room. Then, the removed fine particles are further transported to a process portion isolated from an exhaust gas passage, and the fine particles are fired in the process portion. Since the process portion is isolated from the exhaust gas passage, the fine particles in the process portion are not returned to the filter main body. Moreover, since the fine particles are transported by the counter air only to the second counter room, it is possible to reduce an amount of the counter air.

The quantity of a residual CH.sub.4, a partial pressure of the oxidization gas and a partial pressure of CO are measured. The quantity of each gas to be supplied into the furnace is controlled according to either one of the values of the partial pressures.

Abstract: A seal structure and capable of reducing a width of a seal portion as much as possible while preventing the seal portion from being broken away. The seal structure for sealing between two members in a fluid-tight or air-tight manner is structured such that the seal portion is formed in at least one of joint surfaces of the two members by continuously printing along a seal portion of the joint portions and that a recess portion or a groove is formed at a middle portion of the seal portion in a widthwise direction.

Abstract: In a method of and apparatus for controlling an atmosphere in a heat treatment furnace according to the present invention, a carburizing is carried out while supplying a hydrocarbon series gas and an oxidization gas into the furnace, and the supply of the hydrocarbon series gas is stopped either when the quantity of a residual CH.sub.4 in the furnace is changed to increasing from decreasing, or when a partial pressure of oxygen in the furnace reaches a predetermined value.

Abstract: The object to be achieved by the present invention is to improve accuracy in determining whether or not it is necessary to terminate antiskid control and to reduce the frequency with which the control is terminated. The solution proposed by the present invention is to stop operation of a hydraulic pump before it is determined that the antiskid control should be terminated during the duty pressure increase operation, whereby fluid pressure in a wheel brake can be raised to a level of fluid pressure in a master cylinder before it is determined that the antiskid control should be terminated, to continue the antiskid control as long as the wheel tends to be locked and to terminate the antiskid control when the wheel does not tend to be locked.

Abstract: According to the present invention, the gradient of duty pressure increase can be adjusted to a best possible value even when an M/C pressure has varied. For example, duty ratio is set to a first set value when a difference between the M/C pressure and a wheel locking pressure is equal to or larger than a predetermined value and to a second set value for a longer pressure increase duration when the difference is smaller than the predetermined value. Then, a brake fluid pressure control valve is operated so that the duty pressure can be increased according to the duty ratio.

Abstract: The main object of the present invention is to permit the non-destructive examination of the embrittlement of two-phase stainless steel. There remains anxiety about the reliability of methods based on conventional formulae because an actual machine is not examined to confirm its degree of embrittlement, and its Charpy impact absorption energy at room temperature cannot be estimated accurately.

Abstract: An anti-skid control system for an automotive vehicle includes a hydraulic pressure source, a wheel brake for braking a wheel, a pressure control valve interposed between the hydraulic pressure source to the wheel brake in order to regulate a hydraulic braking pressure supplied from the hydraulic pressure source and the wheel brake, the pressure control valve being brought into a duty-cycle pressure-increasing mode operation and a pressure-decreasing mode operation for increasing and decreasing the hydraulic braking pressure, respectively. The duty-cycle pressure-increasing mode operation are repeated such that the pressure-decreasing mode operation is established therebetween. A later pressure-increasing mode operation is treated as a succession of the previous pressure-increasing mode operation if a time duration required for the pressure-decreasing mode operation between the previous and later pressure-increasing mode operations is less than a set value.

A rear wheel brake fluid pressure control unit determines whether the brake fluid pressure in the rear wheel brake should be increased or decreased according to the rotational condition of the rear wheel which is braked by the rear wheel brake, and activates the second electromagnetic valve and the hydraulic pressure pump driven to decrease or increase the brake fluid pressure in the rear wheel brake according to a determination.
