摘要:
A cooling system for an engine having a plurality of cylinder bores which are arranged along a longitudinal axis. First and second coolant passages continuously extend along the periphery of the bores on each side of the axis, extending from the bore arranged in one end of the engine to the bore arranged in another end of the engine. The first and the second passages are connected to each other by a connector at one end of the engine. Intermediate walls are formed between adjacent bores. A connecting passage is formed in each intermediate wall for connecting the first and the second coolant passages. Water as a coolant flows from an inlet, which is formed at the other end of the first coolant passage, through, in turn, the first coolant passage, the connector, and the second coolant passage, and flows out from an outlet, which is formed at the other end of the second coolant passage. Water also flows through the connecting passages.

An engine compartment structure of a vehicle for introducing cool air into an air intake port without a baffle plate is provided. The structure is constructed such that an air intake port is located behind a first headlamp in the engine compartment, the opening of the air intake port is directed toward the front of the compartment, and the rotational direction of cooling fans for the radiator is determined such that the air discharged by the one or more radiator cooling fans is directed away from the location of the intake air port of the engine, and towards a side behind a second headlamp which is opposite to the first headlamp in the engine compartment.
摘要:
An engine compartment structure for introducing cool air into an air intake port without providing a baffle plate is constructed such that air discharged by cooling fans is directed away from the air intake port. A rotational direction of a second cooling fan of a pair of cooling fans can be opposite to the first cooling fan. The first cooling fan is closer to the air intake port than the second cooling fan. Air volume discharged by the first cooling fan can also be larger than that of the second cooling fan. Furthermore, rotational directions of the pair of cooling fans can be selected such that the air discharged by the cooling fans is directed toward a space at the rear side of the opposite headlamp, and each air volume discharged by the respective cooling fan set differently.

An image forming apparatus having a drawer unit that includes therein a paper-feeding conveying path for conveying a recording medium conveyed from a paper feeding unit on which the recording media are stacked to an image forming unit and/or a discharge conveying path for conveying the recording medium on which an image has been formed to a discharging unit, and be drawn out from an apparatus main body; a lock unit that locks the drawer unit to the apparatus main body; a straddle detecting unit that detects whether the recording medium straddles a conveying path in the apparatus main body and a conveying path in the drawer unit; and a controller that controls the lock unit to lock the drawer unit to the apparatus main body when the straddle detecting unit detects the straddle.
摘要:
A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.
摘要:
A digital broadcast receiver capable of reducing time and labor to back-up contents recorded on one recording medium to another recording medium. A digital broadcast receiver extracts the contents recorded, out of order, on a first recording medium by an extracting unit according to the titles or genres recorded in a content list, and automatically rearranges the extracted contents using an arranging unit according to video-recording date-and-hour recorded in the content list, for recording as a content list onto a second recording medium (300).

A polymerization catalyst composition for a radically polymerizable monomer of the present invention comprises a transition metal-containing phosphazenium composition which is produced by mixing a phosphazenium compound with a compound of a transition metal belonging to Groups 4 to 12 in the periodic table and an organic halogen compound.
摘要:
A recording medium containing a substantially colorless compound in which at least 10 atoms having conjugate π electrons are present on a per-molecule basis, wherein it is especially preferable that the compound has at least two aromatic ring groups and/or shows no fluorescence. An ink composition used for printing in image form on media, with the composition containing a dye and controlling a hue change caused in the printed images over a period of one hour immediately after the printing to 5 or below in color-difference terms. And a method of recording images on media by printing an ink composition in image form, wherein the ink composition contains a dye and a hue change caused in the printed images over a period of one hour immediately after the printing is controlled to 5 or below in color-difference terms.
摘要:
In a gas-fueled internal combustion engine, an ignition device (16, 6O, 62, 64, 66) is arranged in a moving direction of a stream of the gaseous fuel injected from an in-cylinder injection valve (40) in a combustion chamber. The ignition device can directly ignite the fuel stream and diffusive combustion of the gaseous fuel can be executed by sequentially injecting the gaseous fuel toward a flame created by the ignition. Further, premix combustion of the gaseous fuel can also be performed by igniting an air-fuel mixture after the gaseous fuel injected from the in-cylinder injection valve has been sufficiently mixed with the air. As an operation mode of the engine, a lean premix combustion operation is selected when the engine is operated in a prescribed operation region, and the operation mode is changed to a diffusive combustion operation when the engine is operated in a higher load operation region than the prescribed operation region.
