摘要:
A master cylinder apparatus of a type of wherein a master cylinder which is in communication through a connecting port with an oil reservoir on its upper side. A piston is provided having at its front and rear surfaces respective elastic cups, whereby the piston may be pushed to advance against the action of a spring on its front side by a push rod. The piston comprises a front main piston and a rear subsidiary piston connected thereto, and is further defined by an axially extending return port communicating between front and rear oil chambers and with a check valve interposed in the return port arranged to be closed by the action of a releasable spring supported by a stopper at the rear surface, during advance motion of the piston.

An antiskid brake device comprising a reference wheel speed signal setting device for setting the slip rate of the wheel so as to have a relatively small value when the value of the vehicle speed signal is large and to have a relatively large value when the value of the vehicle speed signal is small, the thus set slip rate of the wheel being added to the vehicle speed signal thereby setting the reference wheel speed signal. The reference wheel speed signal setting device comprises an input section for receiving the vehicle speed signal, a logical operation section for setting such slip rate of the wheel and adding the slip rate to the vehicle speed signal for determination of the reference wheel speed signal, and an output section for delivering the reference wheel speed signal. The operational section comprises an operational amplifier, division circuits including resistors, and gain control circuits including resistors and a diode.

An anti-skid braking system for a vehicle comprising a brake unit actuated by pressure generated in a master cylinder by driver actuation and a hydraulic control circuit for hydraulically controlling the actuation of the brake unit to reduce the braking action of the brake unit when an excessive braking force is applied by the brake unit to the brakes of the vehicle wheels. The hydraulic control circuit includes an output section to which a safety valve is connected for releasing the oil pressure when the pressure in the hydraulic control circuit is supplied for a period exceeding a predetermined time.

An anti-skid brake control device including a wheel cylinder having defined therein a first hydraulic chamber connected with a brake fluid line extending from the master cylinder and a second hydraulic chamber connected with a pressure controlling fluid circuit. As the brake fluid line is isolated from the pressure controlling circuit by the output member of the wheel cylinder, the brake system can operate effectively, though in a conventional manner, should oil leakage occur in the controlling circuit. On a four-wheeled vehicle, each pair of front or rear wheel cylinders can be served by a common arrangement of such pressure controlling circuit for anti-skid control.
摘要:
A method for selectively capturing metal ions by treating a solution conting ions of heavy metals, such as cupric ions, zinc ions, etc., at an adjusted pH value with a metal capturing agent comprising a condensation product of a higher fatty acid or derivative thereof with an excess of a polyamine, for example, a condensation product of decanoic acid and a polyamine. Heavy metal ions contained in effluents from mines and factories are selectively captured and separated according to this method.

A tomographic-image pickup unit is controlled so as to capture a tomographic image in response to a signal input from a signal input unit. Then, a display unit is controlled so as to display the captured. tomographic image. An eyeground-image pickup unit is controlled so as to capture a two-dimensional image in response to a signal input from the signal input unit while the tomographic image. is displayed on the display unit. Therewith, the user can more easily perform imaging, and the time load on the subject is reduced.

A conductor connection tool includes a terminal platform base, a conduction fitting accommodated in a fitting recessed part of the terminal platform base. The conduction fitting is formed in a substantially U shape and includes a bottom plate portion, a vertical portion bent vertically upward from one end of the bottom plate portion, and an attachment portion extending from an upper end of the vertical portion in parallel to the bottom plate portion, and having a terminal portion extending in the opposite direction to the attachment portion. A plate spring bent in a substantially V shape with one side serving as an attachment piece to be fixed to the attachment portion of the conduction fitting with the other side serving as a locking piece whose front end is to be brought into pressure contact with the bottom plate portion of the conduction fitting.
