Abstract: A separation tool for a liquid gasket adhesive unit is configured to separate two members from each other by detaching the two members. The two members include respective end surfaces adhered to each other with the liquid gasket adhesive unit interposed therebetween. The separation tool includes a wedge member and a rotary sawing cutter. The wedge member is configured to be pressed by a pressing part into a gap between the end surfaces of the two members between which the liquid gasket adhesive unit is interposed. The rotary sawing cutter is held inside the wedge member, and is configured to be moved separately from the wedge member in a direction toward the liquid gasket adhesive unit in the gap between the end surfaces of the two members pressed apart by the wedge member.

Abstract: A target detection device is provided, which includes a transmission array and a signal generator. The transmission array includes a plurality of transmission elements configured to convert an electric signal into a transmission wave. The signal generator generates first and second sets of electric signals, each set being generated with different phase settings. The signal generator groups the transmission elements according to grouping configurations including first and second grouping configurations. In the first grouping configuration, the plurality of transmission elements are grouped into a plurality of groups each having p transmission elements, and, in the second grouping configuration, the plurality of transmission elements are grouped into a plurality of groups each having q transmission elements.

Abstract: A target detection device is provided. The target detection device includes a transmission array having a plurality of transmission transducer elements. The target detection device further includes a signal generator. The signal generator generates a plurality of transmission signals. The signal generator further changes a phase of a base signal by a phase shift amount that changes over time for generating each of the plurality of transmission signals. Furthermore, the signal generator provides inputs to each transmission transducer element of the plurality of transmission transducer elements with one of the plurality of transmission signals.

Abstract: The present disclosure provides a target object detection device. The target object detection device includes a first transmission signal generator, a first transmission array, a first switch, and a controller. The first transmission signal generator is configured to generate a first transmission signal. The first transmission array includes a plurality of first transmission elements configured to convert the first transmission signal into a transmission wave. The first switch is configured to supply the first transmission signal to one of the first transmission elements in the first transmission array. The controller is configured to control the first switch to switch the first transmission element to which the first transmission signal is supplied from a first element to a second element at a first timing.
