摘要:
A pair of magnetic flux collecting rings and a magnetic sensor are integrally covered by a molded resin to form a sub unit of a torque sensor. The pair of rings and sensors are integrated and are in contact with each other, i.e., the magnetic sensor is held in between respective magnetic flux collecting portions of the rings without any air gap formed therebetween. Magnetic flux collected by the rings can be detected by the magnetic sensor to a maximum degree, whereby the signal output of the magnetic sensor is enhanced and made stable.

A torsion bar type torque sensor system is provided with the following: an elastic member that receives a torque and converts the torque to a torsion displacement; a multipolar ring magnet in which N poles and S poles are circumferentially and alternately magnetized; a pair of magnetic yoke halves disposed coaxially with the ring magnet; and a magnetometric sensor that detects magnetic flux generated between the pair of the magnetic yoke halves. The magnetometric sensor is made of a semiconductor that integrates a semiconductor magnetometric sensor, a non-volatile memory, a computation circuit, and an output circuit. This structure provides a torque sensor system that has an excellent maintainability.

When oil flows from within a seat valve along an oil path in a valve, structure is such that a negative pressure is generated to draw a ball in the direction of the seat valve. That is, the force in the direction of valve closure is actively utilized, the valve does not perform a full stroke in a certain differential pressure range, and increases in a pulsed manner in a minute-stroke state, i.e., in a state where the passage cross-sectional area of the valve is small. Therefore, effective control becomes possible without a large pressure increase.

A brake system capable of implementing anti-skid and traction control operations has an electromagnetic valve for connecting a master cylinder to a wheel cylinder and for disconnecting the master cylinder from the wheel cylinder when anti-skid or traction control is executed. A piezo-electric hydraulic pump is provided for introducing high-pressure brake oil when anti-skid or traction control is executed. A pressure reduction valve selectively introduces and removes brake oil so that a desired wheel cylinder pressure can be attained when anti-skid or traction control is executed. A hydraulic switching valve is connected to the main oil pressure line parallel to the electromagnetic valve and allows pressure in the master cylinder to be opened to the wheel cylinder during a braking operation. The system also includes a unit for establishing one-way communication from the wheel cylinder to the master cylinder during anti-skid control to prevent pressure in the wheel cylinder from being higher than that in the master cylinder while preventing connection between the master cylinder and the wheel cylinder during traction control.
摘要:
A system for carrying out a cooperative control operation for a plurality of automated devices connected together in which the individual operations of the automated device can be controlled individually in accordance with a program. In the control method in this system, the controlling of various automated devices is practiced by inputting a program described in a language which has a unified system, and translating this program in accordance with the combination of the automated devices.

A color image forming apparatus including an image bearing member movable along an endless path, on which color toner images are formed, a transfer material supporting member movable along an endless path for supporting a transfer material and conveying it to an image transfer position where the color toner images are superimposed and transferred sequentially to the transfer material. Also provided are a first driving motor for driving the image bearing member, and a second driving motor, separately provided from the first motor, for driving the transfer material supporting member. In addition, the apparatus includes a detector for detecting the speed of the surface of the transfer material, a discriminator for determining whether the speed variations detected by the detector are within a tolerable range, and a control, responsive to the discriminator, for stopping the operation of a subsequent image transfer step when the detected speed variation is beyond the tolerable range, and for repeating latent image forming, developing, and transfer steps.
摘要:
A rotary vane type compressor provided with a rotor member arranged eccentrically in the cylindrical housing. Vane plates are radially slidably arranged in the rotor member, so that the vane plates always contact an inner cylindrical surface of the housing. Valve means are provided for a positive close-off of the supply of oil during non-operation of the compressor while maintaining a supply of oil in a necessary amount during operation of the compressor. The compressor further includes an oil reservoir arranged in the rotor member for storing an amount of oil to be directed to a pair of bearing units.
摘要:
A rotary compressor includes a cylindrical-shaped housing, a rotor rotatably mounted in the housing and formed with diametrically extending slits, and a pair of movable vanes each slidably disposed in each of the slits with its opposite ends extending beyond the associated slit in abutting relation to the inner surface of the housing. The clearances between the movable vanes and the slits of the rotor are made larger about the central portion of the rotor than adjacent to the outer periphery thereof by making each of the vanes thinner about its central portion than at its opposite end portions or making each of the slits wider about the central portion of the rotor than adjacent to the outer periphery of the rotor. With the arrangement, shearing stresses caused by shearing of oil in the compressor can be suppressed to thereby reduce a loss in the torque of the compressor, and the maximum stress on the movable vanes can be limited below an allowable stress to improve the anti-breakage characteristics of the vanes.
