Abstract: A construction is realized in which a large difference in operation force to operate an adjustment lever 24a never occurs irrespective of a vertical position of a steering wheel and which is produced at low costs. In part of a supporting plate portion 15a of a pair of left and right supporting plate portions 15a which make up a supporting bracket 14a, a thickness of a peripheral portion 34 which surrounds a vertically elongated hole 17a is made small at an upper portion and large at a lower portion. Additionally, a change in operation force of the adjustment lever 24a based on the difference in thickness and a change in the operation force based on a difference in rigidity of the supporting plate portion 15a are offset by each other to thereby solve the problem.

Abstract: A tilt steering column device is provided having construction in which a displacement bracket 16a is provided on the top side of the steering column 6a and that suppresses an increase in operation force for operating an adjustment lever even when the steering wheel 1 is located at the top end of the adjustment range. A wide section 33 having a width dimension that is larger than the width dimension in the forward-backward direction of an anchor section 25 or the top-half section of a pushing member 29 is provided in the top-end section of at least one long hole 17a of a pair of long holes 17a, 17b that are provided in support plate sections 15b, 15c.

Abstract: A semiconductor device includes a first CPU, a second CPU having a configuration that is the same as or comparable to a configuration of the first CPU, and a comparator that compares an output of the first CPU with an output of the second CPU. The second CPU is made so as to have a lower operating margin than the first CPU. By supplying a same signal to the first CPU and the second CPU and then detecting a mismatch between the outputs of the first CPU and the second CPU as a result of comparison, the abnormality is predicted. The semiconductor device includes a reset control circuit that resets the device when the result of comparison by the comparator indicates an error.

Abstract: A memory checking system according to the present invention includes a memory that stores a data to be checked, a check circuit that checks the memory by using the data to be checked and a reference check code of the data to be checked, and a transfer circuit that transfers the data to be checked from the memory to the check circuit based on a transfer setting information of the data to be checked. The transfer setting information is registered in advance in the memory.

Abstract: A semiconductor integrated circuit according to the present invention comprises a power supply circuit for supplying an internal circuit with power, a first regulator for providing a regulated voltage for the power supply circuit, a second regulator for additionally providing the regulated voltage for the power supply circuit so as to compensate for a voltage drop level in the internal circuit, and a voltage drop determining unit for determining the drop of the power supply voltage in the internal circuit based on an output of a power supply voltage monitoring cell in the internal circuit and correspondingly activating the second regulator upon the determination of the generation of the voltage drop. As a component constituting the voltage drop determining unit, a voltage drop detecting circuit, an A/D conversion circuit, a D/A conversion circuit, or the like, can be used.
