Abstract: A power conversion device includes a backup power source as a power source for a discharge controller that discharges electric charges of a capacitor, and an abnormal state in the backup power source or loads is not capable of being dealt with when power is supplied to loads from the backup power source, which makes an output voltage of the backup power source be in an abnormal state. In order to solve the problem, when an abnormality occurs in the backup power source or in loads and the abnormality is detected in power supply from the backup power source, a place where the abnormality occurs is specified. When the specified place where the abnormality occurs is a load, power supply to the load is stopped, thereby preventing the output voltage of the backup power source from being abnormal even when an abnormality occurs in part of power supply destinations.

Abstract: An electric load control apparatus includes an inverter connected to input terminals of an electric storage device, and having output terminals connected via output electric power lines to an electric motor. The inverter includes switching elements, which are controlled to energize the electric motor with electric power stored in the electric storage device. A noise removal filter disposed on at least a portion of the output electric power lines includes a bendable sheet made of a magnetic material wound around the output electric power lines, with air gaps disposed between coiled sheet layers of the wound sheet.

Abstract: A load driving device includes a power storage device, a first power converter, a ring-shaped filter, a first output-side power line, and a first input-side power line. The first output-side power line extends through an opening so that a first output-side common mode current caused by switching the first switching element flows inside the opening through the first output-side power line in a first output-side flow direction. The first input-side power line extends through the opening so that a first input-side common mode current caused by switching the first switching element flows inside the opening through the first input-side power line in a first input-side flow direction same as the first output-side flow direction.

Abstract: A call connection number management unit acquires the number of call connections. A server suspension control unit transfers a calling process allocated to a call control server selected based on the number of call connections for each of call control servers to the call control server, and suspends the call control server when the calling process allocated to the call control server ceases. An assignment control unit assigns a request to the call control server to which the calling process responding to the request has been transferred, when the call control server that has performed the calling process responding to the request is suspended. A prediction activation control unit calculates a change rate of an increase rate of the number of calls, obtains a prediction value of the number of calls based on the change rate, and when the prediction value exceeds a value, activates the suspended call control server.

Abstract: Internal defects formed within a substrate tire for manufacturing a retreaded tire are detected in a non-destructive manner by rotating the inflated tire at a constant speed of 1 r.p.m. while a displacement sensor is urged against an outer surface of the tire at different pressures to derive first and second sets of displacement signals, deriving displacement differences between the first and second displacement signals at corresponding measuring points on the outer surface of the tire, deriving a minimum value of the displacement differences, calculating deviations between the displacement differences and the minimum value, deriving the maximum deviation, and by comparing the maximum deviation with a first threshold value. When the maximum deviation exceeds the first threshold value, it can be judged that the tire includes a local separation. Further an average of the displacement differences is derived and is compared with a second threshold value.

Abstract: Defects such as separations formed within a pneumatic tire are detected in the non-destructive manner by rotating the inflated tire with respect to a pair of displacement sensors which are urged against an outer surface of the tire at a substantially zero pressure and a higher pressure, respectively, measuring displacement values of the sensors over one revolution of the tire, and deriving differences between displacement values at corresponding measuring points on the tire surface. The defects can be detected precisely without being affected by the deformation and radial runout of the tire itself.
