摘要:
A propelling apparatus for a vehicle switchable between a four wheel drive mode and a two wheel drive mode. The apparatus comprises a hydraulic pump for driving hydraulic motors associated with front wheels and rear wheels, respectively. A shutoff valve is provided on oil lines extending between the hydraulic pump and one of the hydraulic motors, e.g. the motor associated with the front wheels. The shutoff valve is operable to establish the two wheel drive mode for driving only the rear wheels. A pumping preventive device prevents the hydraulic motor associated with the front wheels from effecting pumping action due to power transmitted from the front wheels when the shutoff valve is operated.

A transmission comprising a change speed mechanism and a differential housed in a transmission case. The change speed mechanism includes drive gears mounted on a transmission shaft, and driven gears meshed with drive gears. The differential includes a differential case having elongated axle-bearing bosses extending to inside walls of the transmission case. The driven gears are mounted on one of the elongated bosses to be rotatable therewith. The differential case is supported by rear wheel axles extending through the transmission case and the elongated bosses.

A diagnosing operation controlling portion compares the magnitude of change of a control instruction value that controls the dislocation of a valve stem to a reference value that has been set in advance, and stops the malfunction evaluation operation in a diagnosing portion if the magnitude of change per unit time in the control instruction value exceeds a reference value. If the magnitude of change per unit time in the control instruction value exceeds the reference value, then the evaluation may be the same as for a case wherein a stick-slip has occurred, even if the operation is functioning properly. In contrast, it is possible to prevent incorrect stick-slip evaluations by stopping the operation of the diagnosing portion when the magnitude of change per unit time in the control instruction value exceeds a reference value.

A high pressure discharge lamp light source device is provided having a quartz glass discharge vessel enclosing two opposed electrodes that are spaced apart by at most 2.0 mm, each electrode having a projection formed at a tip end thereof, at least 0.20 mg/mm3 of mercury and a halogen; and a power supply device for supplying alternating current to the lamp, The power supply device is adapted to switch between a nominal electric power lighting mode and a low electric power lighting mode having a defined current value in a range of 40 to 70% of a nominal electric power consumption. In the low power mode, the power supply alternately supplies a base current in a range between 100 Hz and 5 kHz a boost current having a higher current value than that of the base current.

A PLL circuit is provided capable of reducing phase noise and facilitating design. In the PLL circuit, a PLL receives a reference frequency and an output from a VC-TCXO, performs a lock operation. In a lock state, a selector selects an output of a first divider that divides the reference frequency. When PLL detects input of reference frequency being lost or an unlock state, the PLL outputs an alarm signal to the selector. When receiving the alarm signal from the PLL, the selector switches from the output of the first divider to an output of a second divider that frequency-divides an output of the VC-TCXO, and outputs the same. Then, a PLL receives an output of the selector and an output of a VCXO and performs a lock operation.

A method for manufacturing a group III nitride crystal on a seed crystal in a holding vessel holding therein a melt containing a group III metal, an alkali metal and nitrogen. The manufacturing method comprises the steps of causing the seed crystal to make a contact with the melt, setting an environment of the seed crystal to a first state offset from a crystal growth condition while in a state in which said seed crystal is in contact with the melt, increasing a nitrogen concentration in the melt, and setting the environment of the seed crystal to a second state suitable for crystal growth when the nitrogen concentration of the melt has reached a concentration suitable for growing the seed crystal.
