Abstract: In a Code Shift Keying (CSK) communication method and apparatus on the signal transmitting side, two Manchester M series equal in code length are produced with a predetermined period. The Manchester M series to actually be transmitted has a maximum value of the absolute value of its autocorrelation which is always larger than that of the cross-correlation of the two Manchester M series. In every predetermined period, one of the two series is selected; the selection depends on whether the transmitting data is "1" or "0", so that the selected series is transmitted as a transmitting signal. On the signal receiving side, a receiving signal is compared with each of two Manchester M series which are the same as those on the signal transmitting side, to provide two correlation outputs. The correlation outputs are subjected to comparison, and the receiving data "0" or "1" is selected according to the result of comparison.

Abstract: A rack and pinion type steering apparatus is provided with a rack guide made of synthetic resin. In the outer pe­riphery of the rack guide, peripheral ribs are formed in the direction of its circumference and axial ribs are formed in its longitudinal direction, respectively. The space formed between those ribs and the inner periphery of a guide bore of the rack guide is set to be generally about the same as the space between a conventional rack guide made of sintered alloy and the inner periphery of the guide bore. As a re­sult, at room temperature, each rib enables the same press performance as the conventional rack guide and the suitable reacting force at steering will be kept. Also at high tem­perature atmosphere, when each rib thermally expands and abuts the guide bore, the outer periphery excluding the portions of the ribs is thermally expanded, thus, thermal creep is prevented and stable engagement of the rack and pinion of the steering apparatus can be maintained at all times.

Abstract: An improved testing apparatus and method for testing the kernel of a microprocessor based unit under test (UUT) where connection to the UUT is made at both the memory connection socket and at the microprocessor with the microprocessor being in place and active in the UUT. The apparatus and method permits subtantially full diagnostics of the kernel to be carried out in a systematic and automated manner in which the requirement of manual probing of the UUT is minimized. Connections at the microprocessor permit the development of high resolution sync signals for verification and evaluation of test results and permit testing without latching of signals on the data bus. The testing protocol implemented in the methodincludes the use of testing primitives which permit the development of a signature for each address and data bus line for the identification of the type as well as the location of any faults discovered by the apparatus. The method of testing exploits bootstrapping techniques including three primitives for bus test, data stimulus and address stimulus to optimize simultaneous testing and circuit fault diagnosis.
