Abstract: In a conventional semiconductor integrated circuit device, a means for preventing a backflow current has a high on-state resistance, which makes it impossible to reduce the voltage loss in normal operation. A semiconductor integrated circuit device of the invention has a first MOS transistor, a second MOS transistor provided between the first MOS transistor and a power supply terminal, and a means that, in normal operation, keeps the gate of the second MOS transistor at a predetermined potential (preferably the ground potential) and that, when a backflow current is likely, turns the second MOS transistor off. This helps prevent a backflow current while reducing the voltage loss in normal operation.

Abstract: Low-pressure-side condensate is subjected to convection heating while dripping in high-pressure-side steam, and to surface turbulent heat transfer due to a circulating flow caused by downflow condensate falling after overflowing. Thus, the temperature of the low-pressure-side condensate can be raised efficiently with satisfactory heat transfer. A bypass connecting pipe enables high-pressure-side condensate to bypass condensate of a reheat chamber and merge with the condensate while keeping a high temperature. Thus, heating of the low-pressure-side condensate is performed sufficiently, with a space for falling being minimized for compactness. Also, condensate in a high amount of heat exchange is fed toward a condensate pump. Hence, a multistage pressure condenser permitting compactness and increased efficiency of a power plant can be constructed.

Abstract: A surveillance image is acquired from a surveillance camera. Supplement information (such as date and time, and surveillance camera number) relating to the surveillance image is acquired. By imaging the supplement information, supplement information image data is generated. A quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on surveillance image data of the surveillance image is added to a quantized discrete cosine transform coefficient block obtained by conducting discrete cosine transform and then quantization on the supplement information image data. A resultant sum is subjected to Huffman encoding. The result is recorded.

Abstract: A cylinder device such as a power cylinder of a power steering system includes a slidable shaft slidably disposed inside a housing. A joint member is connected to the end section of the slidable shaft. A stopper member is disposed between the slidable shaft and the joint member. Here, the end section of the slidable shaft is cutout to form an axial engagement surface. The slidable shaft and the joint member are connected in a condition where the end face of the slidable shaft is in contact with the end face of the joint member so as to from a groove between the axial engagement surface and the joint member. The stopper member is formed annular and has an engagement section formed along its inner periphery. The engagement section is fitted in the groove so that the stopper member is prevented from at least an axial movement.

Abstract: A power supply apparatus has a regulator and a regulator protection circuit. On detecting an abnormality, an abnormality detection circuit in the regulator protection circuit turns the regulator off. Based on the output of the abnormality detection circuit, an abnormality detection incidence checking circuit in the regulator protection circuit checks whether or not an abnormality has been detected a predetermined number of times within a predetermined length of time. When the abnormality detection incidence checking circuit recognizes that an abnormality has been detected the predetermined number of times within the predetermined length of time, an abnormality detection level setting circuit in the regulator protection circuit decreases the detection level of the abnormality detection circuit. This helps reduce the incidence of malfunctioning of the load to which the regulator feeds its output due to repeated detection of an abnormality and recovery therefrom.
