    摘要: First cooling air (50) enters an engine room (1) through a cooling air inlet port (7a) from the exterior of the engine room (1), and is throttled by a suction tube (8a) after passing heat exchangers such as an intercooler (6a), an oil cooler (6b) and a radiator (6c), followed by entering a centrifugal fan (4). The first cooling air (50) is then blown off toward an outer circumference of the centrifugal fan (4). Second cooling air enters the engine room (1) through cooling air inlet ports (7b, 7b) from the exterior of the engine room (1), and flows around an engine (5), various electric equipments such as an alternator (10), and an oil pan (14) while cooling them. The second cooling air is then throttled by a suction tube (8b) before entering the centrifugal fan (4), and blown off toward the outer circumference of the centrifugal fan (4). Two streams of the first and second cooling air (50, 51) are discharged to the exterior through an exhaust port (9). This arrangement enhances the degree of sealing on the engine (5) side to reduce noise, and improves the effect of cooling the electric equipments (10) for higher reliability of the electric equipments (10).

    摘要: A low-noise, small-sized and inexpensive thermal-head type recording device. The timing of the signal for commencing the driving of a paper feed motor is delayed by a predetermined period, e.g., 5 to 20 mS, after the signal for commencing one-line recording by the thermal head, thereby minimizing the force required for separating the sticking recording paper sheet from the thermal head.

    摘要: An air-cooled information processing apparatus has a plurality of units and a casing accommodating the units. At least one cooling air supply section and at least one cooling air discharge section are provided in the casing, for supplying cooling air into the apparatus and for discharging the air therefrom. A partition member divides the space inside the casing so as to define at least two cooling air flow channels between the cooling air supply section and the cooling air discharge section. At least one main fan unit is disposed in each of the cooling air flow channels. The cooling air flow channels include at least one first cooling air flow channel in which at least two units from among the plurality of units are disposed in parallel with each other with respect to the direction of flow of cooling air, and at least one second cooling air flow channel in which at least two units from among the plurality of units are arranged in series to each other along the flow of cooling air. This cooling arrangement ensures optimum cooling for different types of units in the apparatus, without being accompanied by rise in the noise level, rate of discharge of air, power consumption and production cost.
