Abstract: A tackifier resin is a reaction product of rosins (A), a ring structure-containing compound (B) capable of reacting with the rosins, and an alcohol (C).

Abstract: A living body search system includes an unmanned moving body and a server connected to the unmanned moving body through a communication network. The unmanned moving body includes a camera, a moving means, and an image data processor. The image data processor is configured to detect a presence of a face of the living individual in an observation image taken by the camera, retrieve image data of the observation image, and transmit the retrieved image data to the server for facial recognition. The server includes a database configured to store individual identification information of the searched-for object, and an individual identifying means configured to compare the image data with the individual identification information to determine whether the living individual in the image data is the searched-for object.

Abstract: A multicopter equipped with a fall prevention device enabling it to prevent the airframe from falling even in case the multicopter has become unable to fly normally for various reasons. A multicopter includes a multicopter main body having rotors which are driven by a power source, a plurality of emergency rotors which are driven by an emergency power source which is different from the power source, abnormality detection sensors for detecting abnormality of the multicopter main body, and an emergency control device, the multicopter being configured such that, when the abnormality detection sensors have detected abnormality of the multicopter main body, the emergency control device performs control to deactivate operation of the rotors and drive the emergency rotors by the emergency power source to prevent a rapid fall of the multicopter.

Abstract: A living body search system includes an unmanned moving body and a server. The body includes: a camera; image data processing for retrieving image data; moving means; and communicating. The server includes: a database configured to record therein search data; and notifies a client. The body and the server are connected to each other through a communication network. The system includes individuals in the image data wherein individual identification information records the database to determine whether the candidate object in the image data is a searched-for object. The system registers, in the server, searched-for data provided in advance from the client. The system compares image data retrieved from the camera with the individual identification information to perform individual recognition. When the image data matches the individual identification information, the system determines that the object has been found. Then, the system notifies the client that the searched-for object has been found.

Abstract: A tackifier resin is a reaction product of rosins (A), a ring structure-containing compound (B) capable of reacting with the rosins, and an alcohol (C).

Abstract: The purpose of the present invention is to provide a tackifier which is superior in adhesiveness under high temperature (heat-resistant holding power) and rough surface adhesiveness to conventional tackifiers produced using rosin acids having a tricyclic skeletal structure. This tackifier is a reaction product of a rosin (A) with an alcohol (B), the rosin (A) containing a rosin acid (a) having a bicyclic skeletal structure. Preferably, the bicyclic skeletal structure is a labdane skeletal structure.

Abstract: A system that realizes transferring voice effectively, at low cost, and safely in a broad area and even in a case where there is a sparse number of target persons to whom voice is intended to be transferred in an area. This is solved by a voice transfer system including an unmanned aerial vehicle capable of standing still at one point in the air and a supervisory center capable of wireless communication with the unmanned aerial vehicle, wherein the unmanned aerial vehicle includes voice output means capable of outputting voice.

Abstract: A connector assembly including the resilient member and two band clamps includes a feature for preventing the band clamps from overlapping with each other when the band clamps are tightened. The band clamps can include projections extending from an outer surface thereof in order to prevent the band clamps from overlapping with each other. Alternatively, one of the members that are being connected via the connector assembly can include an additional member configured to be aligned with a projection on one of the band clamps.
