摘要:
A crushing and particle sizing apparatus for granular material in which the particle size can be controlled without the use of a screen or similar apparatus. A gap region is formed as a particle size adjusting region which allows particles suited to the gap setting to pass. Particles not suited to the gap setting are brought into rotational contact with a rotating body and crushed to the suited gap setting.

A cassette tape player of a type wherein a cassette which has been inserted horizontally into the player, is moved vertically so as to be set in the playing position. The player has means for slightly moving back the cassette horizontally before it is moved vertically subsequently to the horizontal insertion, and means for managing the ejecting, forwarding, and rewinding operations, as well as release from the forwarding or rewinding operation to the normal playing condition, by making use of an axial movement and a rotation of a single shaft.

Process for preparing polyalkyl-2-alkoxy-7-hydroxychroman derivative of the general formula (V): ##STR1## wherein R.sup.1 denotes lower primary alkyl, R.sup.2 denotes hydrogen or lower primary alkyl and R.sup.3 denotes loweralkyl, by reacting resorcin with either an aliphatic ketone of the general formula (I): ##STR2## wherein R.sup.1 and R.sup.2 are as defined above, and an alcohol of the formula (II):R.sup.3 OH (II)wherein R.sup.3 is as defined above, in the presence of an acid catalyst, or an aliphatic ketone acetal of the general formula (III): ##STR3## wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above, in the presence of an acid catalyst.

A vehicle steering system includes a steering angle detecting unit; a reaction force actuator; and a reaction force actuator control unit. The reaction force actuator control unit determines whether the steering angle detected by the steering angle detecting unit is within a first steering angle range where the steering angle is smaller than or equal to a first change angle or a second steering angle range where the steering angle is larger than the first change angle, and controls the reaction force actuator such that the steering reaction force is increased to a maximum value with an increase in the steering angle when the steering angle is within the first steering angle range and the steering reaction force is monotonically decreased from the maximum value with an increase in the steering angle when the steering angle is within the second steering angle range.

A motor vehicle steering system includes a steered shaft inserted through a tubular housing and a screw shaft provided on the intermediate portion of the steered shaft. A ball nut threadably engaged on the screw shaft via balls is driven to rotate by electric motors. A first bushing and a second bushing held by the housing support the first end portion and the second end portion of the steered shaft slidably in the axial direction, respectively. The central axis of the intermediate portion of the steered shaft is offset from the central axis of the first end portion and the central axis of the second end portion of the steered shaft. The central axis of the ball nut and the central axis of the intermediate portion of the steered shaft match each other.

When a motor vehicle is steered, as turning reaction forces from the road surface, for example, rearward radial loads are applied from rear wheels to corresponding end portions of a steered shaft via corresponding knuckles and corresponding tie rods. A motor vehicle steering system includes first and second counter load application mechanisms that apply counter loads against the radial loads to the corresponding end portions of the steered shaft. Each of the counter load application mechanisms includes a motion conversion mechanism that converts torsional motion of the corresponding end portion of an axle beam caused by a ground contact reaction force of the corresponding rear wheel via the corresponding knuckle and a corresponding king pin into, for example, forward motion of the corresponding end portion of the steered shaft.

According to the invention, in digital television broadcasting by a hierarchical transmission method, even if the receiving condition deteriorates and gives rise to any uncorrectable transmission error in streams, the deterioration of the quality of video and audio signals can be restrained to the minimum. The digital broadcasting receiving apparatus, after separating transmission streams of a plurality of levels into video and audio basic streams, subdivides the data of each stream and detects any error. Data which have been normally decoded are selected according to the relative priority of a designated level macro-block by macro-block or slice by slice for video data and frame by frame for audio data, and video and audio signals are thereby generated. Boundary parts of data of different levels are smoothed.
