摘要： An air-conditioning garment includes a garment main part that is worn on the upper body of a wearer, and two fans that are attached to a lower part of a back part of a garment main part, and configured to feed outside air into the inside of the garment main part. Each of the two fans includes a fan main body and a case that houses the fan main body and includes two air outlets. The two air outlets are formed so that their blowing directions are restricted to being upward or obliquely upward. The two air outlets are formed in such a manner that their blowing directions have an upwardly-opened V-shape.

摘要： A method including measuring a near-infrared absorption spectrum of a hydrogenated compound in the form of a molten resin from which a hydrogenation solvent is separated to calculate an aromatic content ratio and a softening point as physical property values of the hydrogenated compound based on analytical curve data. At least one of a temperature, pressure, reaction time and hydrogen content in a hydrogenating portion is controlled such that a difference between the aromatic content ratio and the bromine number measured in the near-infrared spectrometry and an aromatic content ratio and bromine number of a target hydrogenated petroleum resin pellet becomes small.

摘要： A system for avoiding congestion in mobile terminal communication, includes (a) a plurality of mobile stations, (b) a plurality of base stations, and (c) a base station controller connected to the base stations through a common communication line. The base station controller (a) monitors an activity ratio of a down common communication line, (b) when it is judged that the activity ratio of a down common communication line may be congested, assigns an order of precedence to each of the mobile stations using the common communication line, based on the number of base stations to which each of the mobile stations concurrently makes communication, and (c) abandons low-rate voice frames at a constant ratio among voice frames of a mobile station to which a low order of precedence is assigned.

摘要： A packet loss frequency calculation unit (102) which counts, from an extracted packet loss pattern, packet losses generated in a predetermined interval representing the interval of a plurality of continuous IP packets as a packet loss of one time, thereby calculating the value as a packet loss frequency. The packet loss frequency calculation unit (102) also calculates a burst packet loss length representing the number of continuously lost packets from the packet loss pattern. An average burst packet loss length within a quality estimation interval is calculated from the burst packet loss length. A packet loss variation index calculation unit (106) derives a packet loss variation index from the average burst packet loss length. On the other hand, an encoding quality calculation unit (103) calculates an encoded video quality value based on the extracted encoding bit rate and frame rate. A video quality estimation unit (104) calculates a video quality value based on the encoded video quality value, packet loss frequency, and packet loss variation index. This allows to properly estimate the quality of a video in which a burst packet loss has occurred.
