摘要： An automobile braking force control apparatus controls braking forces on some or all of the wheels individually or in groups. The operating force from a brake pedal (2) is converted into a hydraulic pressure by a master cylinder (3). This converted hydraulic pressure acts on the pistons of actuators (7a, 7b, 7c, 7d) disposed in operating channels (6a, 6b, 6c, 6d) leading to some or all of the wheels taken individually or in groups. The braking force on the wheels vary with the movements of the pistons. Auxiliary power circuits (8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d) are provided for enabling hydraulic pressure from an auxiliary power source (12) to act on the pistons of the actuators (7a, 7b, 7c, 7d). Control valves (10a, 10b, 10c, 10d) controled by an electronic control device (13) are disposed in auxiliary power circuits. In addition to the hydraulic pressure from the master cylinder (3), the pistons of the actuators (7a, 7b, 7c, 7d) are acted on by the auxiliary hydraulic pressures from the auxiliary power source (12) in both positive and negative directions, after these pressures have been controlled to suitable magnitudes by the control valves (10a, 10b, 10c, 10d).

摘要： An improved booster for use with a master cylinder in a brake system is proposed which includes a spring for keeping the input shaft away from the booster piston. The spring has one end abutting on a piston acted by the auxiliary pressure from the auxiliary power source and the other end abutting on the brake pedal to bear the pedal stepping force. The input shaft will not engage the booster piston except in case of the failure of the auxiliary power source, ect.

摘要： A wheel brake fluid pressure control device has a main fluid line and a return-flow type antilock control function. This device also has a fluid supply line branching from the main fluid line so that it has a traction control function as well. It is necessary to provide such a device with a shutoff valve for checking the fluid flow from the fluid supply line to the discharged fluid reservoir while the master cylinder is being pressurized. The shutoff valve employed is not an expensive solenoid valve or a pressure-responsive valve, but a pressure-responsive type check valve which closes when the brake pressure in the discharge line exceeds a predetermined level. This shutoff valve is simple in structure and low in cost and can improve the reliability of the entire device. Also, by using this valve, the traction control function can be added to an existing antilock control device at a low cost.

摘要： The present invention relates to a process for producing a porous glass preform for an optical fiber and an apparatus for conducting such a process. According to the process, fine glass particles are produced by heating and reacting vaporous starting materials in a reaction vessel. The resulting fine glass particles are thereafter deposited to obtain the porous glass preform. An exhaust gas containing non-deposited fine glass particles is exhausted through an exhaust duct at a velocity above 15 m/sec. Preferably, pressure fluctuation in the reaction vessel is minimized by supplying air from outside of the reaction vessel to the exhaust duct. In accordance with the present invention, the exhaust duct is less likely to become obstructed by non-deposited fine glass particles. As a result, the preform can be produced without interruption over an extended period of time.

摘要： A vehicle travel direction estimating device is provided which has a wheel speed calculating device for calculating the speed and acceleration Aw of a vehicle. In addition, a gravity-type accelerometer is provided for producing a gravitationally detected acceleration Am. When both Aw and Am increase or decrease simultaneously, it is determined that the vehicle is travelling forward, and when one of Aw and Am increases while the other decreases, it is determined that the vehicle is travelling in reverse. To detect this feature, a calculating system is provided to form differential values Daw and Dam from accelerations Aw and Am. The vehicle travel direction is estimated using the differential values Daw and Dam.

摘要： A fluid pressure controller having a housing having a first port and a second port, and a spool axially slidably mounted in the housing. First and second chambers are defined between opposing ends of the spool between the spool and the housing. The controller further has an electricity/power converter for applying to the spool an axial driving force corresponding to the magnitude of an electric command, and a spring for holding the spool in its initial position when the value of the electric command to the converter is zero. A variable-size orifice is provided to separately control communications between the first chamber and the first port depending upon the axial position of the spool. The second chamber normally communicates with the second port. A fixed-size orifice and a relief valve are provided parallel to each other in passages connecting the first and second chambers.

摘要： A proportioning control valve for an antilock control device having a cylinder and first and second pistons mounted therein. The first piston has braking output pressure and first input pressure receiving portions. The second piston slidably mounted on a small-diameter portion of the first piston has a second input pressure receiving portion. A spring is interposed between the two pistons to bias them away from each other. A stopper is provided between the two pistons to limit the movement of the second piston toward the first piston. The cylinder is formed with a control input pressure port communicating with the input pressure receiving portion and an output pressure port communicating with the output pressure receiving portion, and a brake pressure input port. With this arrangement, the output pressure which acts on the output pressure receiving portion of the first piston will counteract the input pressure while the input pressure is below the cutting point and will counteract the sum of the input pressure which acts on the first input pressure receiving portion and the bias of the spring after the input pressure has reached the cutting point. Thus the ratio between the input and output pressures is adjustable by varying the total area of the input pressure receiving portions before reaching the cutting point, and by varying the area of the first input pressure receiving portion and bias of the spring after the cutting point has been reached.
