    摘要： A method for preparing a phenylalanine derivative having a quinazoline-dione ring represented by the following formula (1) or a pharmaceutically acceptable salt thereof, comprising the following steps (a), (b) and (c): (a) reacting an acyl phenylalanine derivative represented by the following formula (2): with a carbonyl group-introducing reagent and a specific anthranilic acid derivative to thus form the corresponding carboxy-asymmetric urea derivative; (b) converting the carboxy-asymmetric urea derivative into the corresponding quinazoline-dione derivative in the presence of a carboxyl group-activating agent: (c) if desired, substituting an N-alkyl group for the hydrogen atom bonded to the nitrogen atom present in the quinazoline-dione ring of the quinazoline-dione derivative using an N-alkylation agent and then deprotecting the resulting product, when the substituent R3′ which is a group corresponding to R3 is protected. According to this method, there can be obtained a phenylalanine derivative having a quinazoline-dione skeleton in a industrially favorably high yield.

    摘要： An acceleration detecting device includes a housing, a weight pivotally mounted inside the housing for rotating along a locus in response to an applied acceleration, a spring provided between the housing and the weight to apply a biasing force to the weight against the applied acceleration, and a contact assembly located outside the locus of the weight. The contact assembly is adapted to be electrically closed by the rotation of the weight. An arc-shaped circumference of the weight maintains the same distance between the weight and the contact assembly during the rotation of the weight. When an excessive acceleration is applied to the device, the weight rotates from an initial position against the biasing force of the spring to electrically close the contact assembly. The weight is returned to the initial position by the biasing force of the spring to electrically open the contact assembly when the excess acceleration is no longer present. Because the spring which applies the biasing force is separated from the contact assembly, the biasing force is reliably maintained for a longer period. Further, the weight can rotate without any interference to the contact assembly because the arc-shaped outer circumference of the weight maintains the contact assembly spaced from the locus of the weight.

    摘要： A crash detection sensor having a supporting member arranged in a space in a door. The supporting member has sufficient strength to maintain its state under normal conditions. First and second electrodes, usually spaced, are provided on the supporting member. A shock larger than a predetermined level applied to the door causes the first and the second electrodes to be brought into contact with each other, thereby allowing a lateral impact to be detected in the door.
