Abstract: An aspect of the present disclosure is to accurately estimate whether or not a plurality of people are in close contact with each other in a target space. An estimation system (1) includes a first estimator (12) and a second estimator (13). The first estimator (12) is configured to estimate, based on a heat distribution including a plurality of heat sources detected by at least one infrared sensor (2), three-dimensional positions of heads of a plurality of people in a target space. The second estimator (13) is configured to estimate, based on data on the three-dimensional positions estimated by the first estimator (12), estimate whether or not the plurality of people are in close contact with each other.

Abstract: A USB jack is provided below a bulging part of a door trim. Therefore, the bulging part can prevent rainwater from entering the USB jack. As a result, the USB jack can be provided on the door trim. In addition, since a connection hole is provided in the bulging part, a USB cable can be arranged to extend from an internal space of a storage part to a lower space of the bulging part through the connection hole. As a result, although the USB jack is provided below the bulging part, the USB jack and a smartphone stored in the storage part can be connected by the USB cable.

Abstract: A liquid ejecting system includes a head unit that includes a nozzle for ejecting a liquid, a pressure chamber communicating with the nozzle, and a drive element for applying pressure fluctuation to a liquid in the pressure chamber by supplying a drive pulse, an acquisition portion that acquires output information regarding a usage condition of the head unit, a first connection portion that is communicably connected to a server through a network, a first output portion that outputs the output information through the first connection portion, a first input portion to which input information regarding a waveform of the drive pulse supplied to the drive element is input through the first connection portion. A decision portion that decides the waveform of the drive pulse supplied to the drive element based on the input information.

Abstract: Provided is a short-circuit detection device including: a signal acquisition unit configured to acquire, from a magnetic flux detector configured to detect a magnetic flux generated in an air gap between a rotor and a stator of a rotating electric machine, a detection signal corresponding to the magnetic flux; a signal processing unit configured to subject the detection signal acquired by the signal acquisition unit to filtering of removing at least one component of odd-order components included in the detection signal, to thereby generate a filtered signal being the detection signal subjected to the filtering; and a short-circuit detection unit configured to detect a short circuit of a field winding through use of the filtered signal generated by the signal processing unit.

Abstract: A surgical robot includes a main body portion, an arm provided on the main body portion to hold an endoscope, an attachment member that detachably attached the main body portion to a table portion of a bed, and a vertical drive mechanism that allows the main body portion to move along a first direction perpendicular to the table portion. The arm is pneumatically driven.

Abstract: A surgical system includes a gripping robot that holds a treatment tool, a storage, and a controller. The storage stores relationship information of a relationship between condition information of a surgery and a position of the gripping robot. The controller sets, based on the relationship information from the storage, an initial position of the gripping robot, and generates a control signal to control the gripping robot to move to the initial position and outputs the control signal to the gripping robot.

Abstract: A surgical robot includes an operating section that receives a pressure from a gas, a pressure generating device that generates the pressure, a pressure detector that detects a pressure supplied from the pressure generating device to the operating section, and a control device configured to implement an operation diagnosis device that makes a determination, using the pressure detected by the pressure detector, whether the operating section is operable, and that notifies a result of the determination.

Abstract: An object is to provide a camera head adaptor that allows an endoscope to be detachably attached with a simple operation and that can prevent stress on electrical wirings, optical cables, etc. in an insertion portion due to a camera head being held. The camera head adaptor for holding an endoscope having a camera head comprises: a holding portion that holds the camera head of the endoscope in a detachable manner; a connecting portion that extends along an observation optical axis of the camera head and can be attached to a support structure; and a coupling portion that couples the holding portion and the connecting portion.

Abstract: An aluminum alloy for heat exchangers, the alloy, comprising a base compostion selected from a group consisting of Al-Mg-Si composition containing 0.1 to 0.8 wt % of Mg, 0.2 to 1.0 wt % of Si and 0.3 to 1.5 wt % of Mn; pure-Al composition; Al-Mg composition containing 0.05 to 1.0 wt % of Mg; and a Al-Zn composition containing 0.05 to 2.0 wt % of Zn. The alloy further comprises 0.01 to 0.3 wt % of Fe and/or 0.01 to 0.3 wt % of Ni, wherein the balance are aluminum of purity of 99.9% or higher and unavoidable impurities contained therein, and content of Cu as one of the impurities is controlled to be 0.05 wt % or less.

Abstract: A method of manufacturing a cathode for magnetron comprises a cathode sleeve formed as a hollow cylinder, a heater inside the sleeve, two end shields formed around the sleeve at a prescribed interval and an electron emitting material applied around the sleeve between both end-shields, wherein a plurality of isolated projections are almost regularly and intergraly formed around the sleeve between the end-shields, and the above electron emitting material is applied onto the cathode sleeve to fill gaps among the plural projections.According to the method of manufacturing a cathode of the present invention, the efficiency of electron emission and electric conductivity are not lowered, whereby the stable operation can be realized for a long term.
