Abstract: A power supply control apparatus, includes: a driver configured to respectively drive an output transistor and a synchronous rectification transistor configured to generate an output voltage from an input voltage and supply the output voltage to a load; and a controller configured to, in a light load mode in which output feedback control is performed such that a switching frequency of the output transistor becomes lower as the load becomes lighter, during an off period from a time at which both the output transistor and the synchronous rectification transistor are turned off to an on timing of the output transistor based on the output feedback control, periodically turn on the synchronous rectification transistor within a range in which the switching frequency does not fall below a predetermined lower limit value.

Abstract: An image processing system processes a read signal read from an imaging plate on which a radiographic image is recorded to generate an X-ray image. The image processing system performs signal processing on the total output area included in the read signal such that the degree of change in density regarding a partial attention region according to the purpose of observation is larger than the degree of change in density regarding the non-attention region other than the attention region.

Abstract: To provide an electromagnetic-wave shielding plate superior in an electromagnetic-wave shielding property, a light-transmitting property and non-visibility of a mesh pattern at low cost. A pattern of a resin layer is printed on a metal layer of a transparent substrate by a printing method. After that, the metal layer is over-etched with the resin layer used as an etching mask, and a part of the resin layer protruding from the remaining metal layer in a plate-surface direction is removed. As a result, an electromagnetic-wave shielding plate superior in an electromagnetic-wave shielding property and non-visibility and having, for example, a pattern line width of 3 ?m or more and 25 ?m or less.

Abstract: The present invention aims to provide a transparent electromagnetic wave shield member, which is free from a moirè phenomenon which could not be solved by the prior art, and in which an excellent electromagnetic wave shielding properties and a sufficient total light transmittance based on an appropriate network structure are compatible, and a method for manufacturing the same. The transparent electromagnetic wave shield member of the present invention is a transparent electromagnetic wave shield member in which a metal layer of an electroconductive metal network structure having a geometrical shape is formed on a transparent substrate, and which is characterized in that a spacing of said network structure is 200 ?m or less, an opening ratio of the network structure is 84% or more, and in addition, a thickness of the electroconductive metal layer is 2 ?m or less.

Abstract: An IG-off-timer measures the time t_off from when an engine is stopped, or an ignition is turned off. An ECU sequentially memorizes an estimated temperature of each of heat generating portions as a memorized temperature. Immediately after the engine is re-started, the ECU sets an initial value of the estimated temperature of each heat generating portion in such a manner that the initial value reflects a temperature drop of the heat generating portion in the deactivation period of the engine. The temperature of the heat generating portion is thus accurately estimated even after re-starting of the engine. The heat generating portions are thus appropriately protected.

Abstract: An ECU estimates the temperatures of the heat generating portions provided in a drive force transmission system, or a transaxle, a rear differential, and a torque coupling, in correspondence with not only the rotational speed (the differential rotational speed) of each heat generating portion and the torque transmission rate of the torque coupling but also the outside temperature detected by an outside temperature sensor. If the estimated temperature of any of the heat generating portions exceeds a respective predetermined temperature, the ECU controls operation of the torque coupling to suppress overheating of the heat generating portion. That is, the temperature of each heat generating portion is accurately detected through a simplified structure and overheating of the heat generating portion is effectively suppressed.

Abstract: Disclosed herein is a driving state switching unit with a synchro-mechanism which employs a synchro-mechanism to perform switching of a driving state. The switching unit is equipped with a first gear (32) and a second gear (33) coaxially disposed, a gear connecting member (34) axially movable so that the first gear (32) and the second gear (33) can be connected, and a synchro-mechanism (35) interposed between the first gear (32) and the second gear (33). By moving the gear connecting member (34) by an electric actuator (50), the first gear (32) and the second gear (33) are connected, while they are being synchronized by the synchro-mechanism (35). When this occurs, control means (102) controls a supply current to the electric actuator (50), and judgement means (102) judges synchronization of the synchro-mechanism (35), based on a change in the supply current value to the electric actuator (50).
