Title: Installation mechanism of bumper reinforcement
Inventor: ISHITOBI HIDEKI
IPC: B60R19/24
Filed: 1995-02-13
Abstract: PURPOSE: To prevent rupture of an installation part even in the case when tensile force works in the longitudinal direction as an automobile collides against a pole by installing a bumper reinforcement on a side member while supporting it free to move in the longitudinal direction of the installation part on both end positions of the bumper reinforcement. CONSTITUTION: In the case when an automobile pole-collides against a columnar thing 4, as installation parts 1b on both end positions are supported by side members 2, a central part of a bumper reinforcement 1 is deformed in a direction of a car body and the installation parts are pulled in the central direction. At this time, the bumper reinforcement 1 is installed on the side members 2 and made free to move in the longitudinal direction by bolting an elliptical through hole 1a and a through hole 2a of the side member 2 by way of matching them with each other. Consequently, as the installation parts 1b move in an arrow direction by a distance equivalent to an amount of displacement in the state that they are bolted when the installation parts 1b are pulled in the central direction, it is possible to prevent rupture of the installation parts 1b.

Title: Decoding device
Inventor: FUKAMI TADASHI
IPC: G11B20/18
Filed: 1986-03-07
Abstract: PURPOSE:To prevent the occurrence of an abnormal sound at a reproducing sound by setting a pointer independently from the result of the error correction of a PCM signal in accordance with the decoding condition of a decoder to decode the error detecting code of an additive code or an error correcting code. CONSTITUTION:An interpolating circuit 38 executes the interpolating action by using a pointer attendant with respective words of a PCM signal from an error correcting circuit 37 usually, and independant of this, the interpolating action is forcibly executed by an interpolating control signal generated from an interpolating control circuit 49. When the amplitudes of the reproducing signals of a magnetic head 2A and a magnetic head 2B come to be smaller, the number of times of deciding that there is no error as the result of the error detection of an error detecting circuit 44, is decreased to (n) or below, the reproducing signal of the magnetic head 2A and 2B comes to be both (n) or below and the output of a number detecting circuit 47 comes to be '1'. Thus, the interpolating control signal to set a pointer forcibly occurs from an interpolating control circuit 49 to both of the reproducing signal of the magnetic heads 2A and 2B. Thus, the occurrence of the abnormal reproducing sound can be prevented without fail.
