    摘要: An oxidation catalyst according to the present invention is prepared, for example, by heat processing a gold compound at 150° C. to 80° C., yielding ultrafine gold particles, which are then mixed with a palladium compound and a compound containing at least one element selected from the group consisting of alkaline metals and the elements of Groups IIA, IIIA, VIA, IIB, VB, and VIII of the Periodic Table. By an oxidation reaction between a benzyl compound such as p-xylene and a carboxylic acid such as acetic acid in the presence of oxygen and the oxidation catalyst prepared as above, a benzyl ester such as p-methylbenzyl acetate or p-xylylene diacetate can be produced. Consequently, it is possible to provide an oxidation catalyst suitable for use in industrially producing the foregoing benzyl esters, a method of preparing the foregoing oxidation catalyst, and a method of producing the foregoing benzyl esters efficiently and at low cost.

    摘要: A first wave of a glass breaking sound has a sharp peak due to an impact sound and thereafter it attenuates rapidly. The attenuating characteristics of the first wave is measured with an attenuating time or a magnitude of attenuation thereof so that whether or not glass breaking has occurred is determined. Since an original waveform obtained by a microphone includes noise, low frequency components are eliminated by a high pass filter. The characteristics of the first wave of the glass breaking sound is almost stable. Therefore, by detecting the characteristics from the first wave, the glass breaking can be detected without errors. Further, since the glass breaking is detected by attenuation of the first wave, the detection can be carried out quickly.

    摘要: An automobile trunk lid having an air spoiler on its upper surface, both being made of a fiber-reinforced plastic and integrally molded in one piece. Since such a trunk lid with an integral air spoiler has no joint therebetween, it has an improved decorative effect and is free from the entry of dust and wax into a joint.

    摘要: A photographic camera provided with flash tube has a voltage detector for detecting the voltage level of a power supply; a control circuit controlled by the detector for preventing start of the photographing operation until the voltage source of the power supply recovers to a predetermined level during charging of a first capacitor for firing of the flash tube; and a second capacitor connected in parallel with the power supply and connected between a primary winding of an electric voltage boosting circuit and the power supply. By this arrangement, the start of the photographing operation is prevented until the voltage level of the power supply is fully recovered after firing of the flash tube and operation of the camera.

    摘要: An extensible stay extending between a rear end closure and the body of the automobile. The stay is attached to the body at the end adjacent to the body through an L-shaped bracket. A bracket cover is provided to cover the L-shaped bracket so as to avoid any danger by having the bracket exposed. The appearance is also improved by the cover.
