Abstract: A clamping apparatus for an adjustable steering column for a vehicle includes at least two, relatively slidable plates (1, 2) that can be clamped relatively to one another. More than two plates can be provided to form a pack of plates. Alternate plates have relatively slidable, clamping surfaces that can contact one another, the respective clamping surfaces of the two plates being made of material of different hardnesses. In use, the softer material of one of the plates will deform due to the rubbing of the material of the harder plate and this increases stiction and friction, thereby converting friction into a sheer stress load.

A second latch circuit temporarily memorizes the display pixel data as a preceding display pixel data that precedes the display pixel data by one line. The load judging circuit judges a transition state of the display pixel data based on the display pixel data and the preceding display pixel data and predicts a drive load capacity CL based on a result of the judgment. A drivability adjusting circuit adjusts a signal level of the display pixel data based on a result of the prediction of the drive load capacity CL and adjusts drivability of an output.

Abstract: When a contention is detected between a memory write address and a display read address in a memory circuit which stores display data, a host retry pulse generating circuit generates a display read signal and a display line data transfer signal based on a memory write clock, and supplies these to the memory circuit while supplying the display line data transfer signal to a line latch circuit. Alternatively, upon detection of the contention above, a same line re-display read processing circuit performs same line re-display read processing without moving to the next line, and supplies a display read signal and a display line data transfer signal to the memory circuit while supplying the display line data transfer signal to the line latch circuit.

The circular outer circumference 26 of the cylindrical portion 22 has eleven ridges 27 formed at an angularly equal spacing to bulge radially outward. When an ignition key is turned to a lock position and pulled from the keyhole, a lock key 19 is protruded toward the axis of a steering shaft 13. As a result, the leading end of the lock key 19 comes into engagement between the side faces 271 and 271 of the adjoining ridges 27 and 27 of the keylock collar 2 so that the steering shaft 13 is fixed with respect to a column 11 thereby to block the rotation of the steering shaft 13.

Abstract: An energy absorbing type intermediate shaft structure to be incorporated into a steering device of an automobile for transmitting a steering force of a steering wheel to a steering gear, has a shaft inserted in a tube. The shaft has a small cross-sectional area portion and a pressing portion. A cover tube is present around the small cross-sectional area portion. The location at which the pressing portion is formed is regulated so that with the pressing portion bearing against the cover tube, one end edge of the cover tube may lie around the small cross-sectional area portion. A distance .alpha. between the pressing portion and the cover tube, a distance .beta. between the cover tube and the tube, and a distance .gamma. between the shaft and a member associated with a yoke in the steering device are set to satisfy the condition .alpha.+.beta.<.gamma..

Abstract: In order to obtain sufficient energy absorbing capacity and, at the same time, to reduce the number of components and simplify assembly, synthetic resin is disposed between a shaft and a tube. The synthetic resin is torn and broken when strong compressive force in the axial direction is given at the time of a car crash, allowing the shaft to be pushed deeply into the tube until it contacts a pin. In this state, the contact position between one end of the tube and a cover tube substantially coincides with a small-cross-section portion formed in an intermediate part of the shaft. As a result, the shaft can bend at the small-cross-section portion.
