摘要:
The present invention provides a construction machine adopting a structure that assures a predetermined sound pressure level along a forward direction relative to the construction machine and allows a warning horn to be miniaturized. Warning horns 12 and 13 are mounted in the vicinity of at least either a left headlamp 9 or a right headlamp 10 provided on the left side and the right side of a vehicle body 3 of the construction machine. The warning horns 12 and 13 are housed inside a bracket 11 used to mount the headlamp 9 or 10. The plurality of warning horns 12 and 13 are disposed on a single side toward the left headlamp 9 or the right headlamp 10. Since a front attachment 7 does not block the sound generated from the warning horns 12 and 13 and thus the warning sound can travel without hindrance along the forward direction, a predetermined sound pressure level is achieved with ease along the forward direction relative to the vehicle body 3.

A crawler carrier capable of smoothly operating a driving force source even at a slant. The driving force source is arranged between a dump body and a cab and laid in a lateral direction and at the same time the driving force source and a heat exchanger are arranged in series in a lateral direction. With such an arrangement as above, the driving force source can be arranged at an upper structure frame under a state in which it becomes substantially horizontal without interfering with the dump body. Even when the crawler carrier performs work at a slant the engine can always be lubricated with lubricant oil and the driving force source can be operated smoothly.

A tired roller is provided with a prime mover and a speed change unit of the HST type. The speed change unit includes an HST hydraulic pump of the variable displacement type driven by the prime mover and an HST hydraulic motor driven by pressure oil from the hydraulic pump, and can change a rotational speed of the hydraulic motor by varying a delivery rate of pressure oil from the hydraulic pump. Rotation of the hydraulic motor is therefore transmitted at a lower speed to a drive-axle tire train. A propeller shaft is connected to the hydraulic motor without interposition of any speed reduction mechanism, so that the propeller shaft is rotated at a high speed with a low torque. This has made it possible to form the propeller shaft smaller in diameter and hence to arrange it in a narrow space between tires in the drive-axle tire train. Further, the rotation of the hydraulic motor is reduced in speed at an output side of the propeller shaft, thereby making it possible to transmit the rotation in a state increased in rotating torque to the drive-axle tire train.

When an external recording medium connected to an interface is removed therefrom and a new external recording medium is connected to the interface, a processor selects either first file analysis information read from a memory or second file analysis information generated based on analysis of data recorded on the new external recording medium as file analysis information to be used for decoding a file stored in the new external recording medium, and the processor makes such selection based on comparison between first recording medium management information and second recording medium management information.

In a tone output device 100, an oscillator 102 outputs a clock 141 that is emitted by a crystal resonator. A multiplication circuit 103 outputs a clock 142 that is generated by multiplying the clock 141. A timing control circuit 104 outputs a timing signal 150 generated based on the clock 142 for operations of a CPU 105. The CPU 105 operates in sync with the timing signal 150. The DA converter 115 operates in sync with a signal generated based on the clock 141. The timing adjustment circuit 114 detects deviation of the clock 142 from the clock 141 resulting from frequency jitter of the clock 142, and prevents occurrence of clock racing.

The present invention provides a clock control type processor which can permit and accommodate a temporary delay in a processing operation also in a system in which processing times are not constant, and realize the accommodation while reducing the power consumption as much as possible. In this clock control type processor, a block difference detection circuit 20 detects a difference between a processing block address and a writing block address and outputs a block difference signal 105, and a clock control circuit 16 controls a clock.
摘要:
In a circuit having MOS transistors connected in series, a surge voltage that occurs during off periods is reduced, while suppressing an increase in switching loss at turning off of the MOS transistors. When a first power MOSFET (1) is turned off and then a second power MOSFET (2) is turned on after that according to predetermined timing, the first power MOSFET (1) is temporarily placed in an on state for a predetermined time period synchronized with that predetermined timing. On the other hand, when the second power MOSFET (2) is turned off and then the first power MOSFET (1) is turned on after that according to predetermined timing, the second power MOSFET (2) is temporarily placed in an on state for a predetermined time period synchronized with that predetermined timing.

An IGBT (121) and a diode (131) are joined onto an element arrangement portion (111a) of a first terminal member (111) and an element arrangement portion (112a) of a second terminal member (112) is joined onto the IGBT (121) and the diode (131). Further, an IGBT (122) and a diode (132) are joined onto the element arrangement portion (112a) of the second terminal member (112) and an element arrangement portion (113a) of a third terminal member (113) is joined onto the IGBT (122) and the diode (132). A transfer mold package (141) is so formed as to house the elements (121, 122, 131, 132). External connection portions (111b, 112b, 113b) of the terminal members (111, 112, 113) are drawn out of the package (141). The element arrangement portion(s) (111a, 113a) of the first and/or third terminal member (111, 113) are/is exposed out of the package (141).
