Abstract: A cooling system for an engine is provided. The cooling system includes coolant flow paths including a first flow path and a second flow path and where coolant circulates, a coolant pump for circulating coolant within the coolant flow paths, a flow rate control valve for adjusting a flow rate of the coolant through the second flow path, a temperature detector for detecting a temperature of the coolant within the first flow path, and a valve controller for adjusting an opening of the flow rate control valve based on the temperature detected by the temperature detector. The first flow path passes through a cylinder head of the engine, and the second flow path branches from the first flow path and passes through auxiliary machinery of the engine.

Abstract: An exhaust control apparatus for an engine is provided. The apparatus includes a turbocharger, a high-pressure exhaust gas recirculation (EGR) device, a low-pressure EGR device, and a flap controller. The turbocharger includes a turbine, a compressor, and movable flaps, and rotates the turbine by exhaust gas to drive the compressor so as to boost intake air. The high-pressure EGR device recirculates, within a first engine operating range, the exhaust gas from a position of an exhaust passage upstream of the turbine to a position of an intake passage downstream of the compressor. The low-pressure EGR device recirculates, within a second engine operating range, the exhaust gas from a position of the exhaust passage downstream of the turbine to a position of the intake passage upstream of the compressor. The flap controller controls flap openings.

Abstract: A cooling system for an engine is provided. The cooling system includes an EGR device including an EGR passage for recirculating exhaust gas into an intake passage, an EGR valve for adjusting a flow rate of the recirculating exhaust gas, and an EGR cooler for cooling the recirculating exhaust gas, an EGR valve controller for controlling the EGR valve, coolant flow paths including a first flow path and a second flow path and where coolant circulates, a coolant pump for circulating coolant within the coolant flow paths, a flow rate control valve for adjusting a flow rate of the coolant through the second flow path, a temperature detector for detecting a coolant temperature within the first flow path, and a valve controller for adjusting a flow rate control valve opening based on the detected temperature.

Abstract: An exhaust gas recirculation control device for an engine is provided. The device includes an EGR passage connecting an exhaust passage of the engine with an intake passage of the engine, an EGR amount adjustor for adjusting an EGR amount that is a recirculation amount of exhaust gas of the engine through the EGR passage, an adjustor controller for controlling the EGR adjustor to adjust the EGR amount, and a gear position detector for detecting a gear position of a transmission of a vehicle on which the engine is mounted. When the gear position detected by the gear position detector during an idle operation of the engine is a non-travel position, the adjustor controller performs an EGR amount increase control in which the EGR amount adjustor is controlled to increase the EGR amount to be higher than when the gear position is a travel position.

Abstract: A portable display equipment includes an image display unit, and an external light preventing member of a polygonal cylinder. The external light preventing member is detachably mounted in front of the display portion of the image display unit. The external light preventing member includes a shielding member and a light-shielding member of a polygonal cylinder. The shielding member covers the periphery of the display portion of the image display unit. The light-shielding member consists of a plurality of light-shielding plates which are coupled to each other so as to be freely bent and constitute one sheet member when developed. The light-shielding member is narrowed toward the viewer side by bending coupling portions of the light-shielding plates. The shielding member is coupled to part of an edge of the light-shielding member on the display side so as to be freely bent.

Abstract: A television receiver employs a liquid crystal display panel mounted in a unit which can be set into either a closed position in which the display panel is disposed within a recessed portion of the case of the television set, and an opened position in which ambient light passes through the display panel to be reflected from a mirror towards the viewer. In conjunction with this arrangement, operating control members are positioned to facilitate one-hand operation of the receiver, and the largest circuit components and batteries are positioned with respect to the display panel and control members such as to minimize the overall size of the receiver.

Abstract: This invention relates to a battery powered electronic wristwatch having a time changing device accommodated in a recess in the base plate of the watch which device operatively is connected to the adjustment shaft manipulatable externally of the watch casing to alter the position of the hands of the watch. The time changing device includes a pivotable setting lever which cooperates with the adjustment shaft and a spring for controlling the movement of the setting lever. A fixed body portion of the spring has a portion of its periphery shaped so as to conform to a peripheral portion of a base recess for accommodating the watch battery.
