摘要： A method of manufacturing semiconductor laser device capable of reducing κL, with manufacturing restrictions satisfied, is provided. In a distributed-feedback or distributed-reflective semiconductor laser device, immediately before burying regrowth of a diffraction grating, halogen-based gas is introduced to a reactor, and etching is performed on the diffraction grating so that each side wall has at least two or more crystal faces and a ratio of length of an upper side in a waveguide direction to a bottom side parallel to a (100) surface is 0 to 0.3. And, a reactive product formed on side surfaces of the diffraction grating and in trench portions between stripes of the diffraction grating at an increase of temperature for regrowth is removed. Therefore, the diffraction grating with reduced height and a sine wave shape is obtained, thereby κL of the device is reduced. Thus, an oscillation threshold and optical output efficiency can be improved.

摘要： An actual fuel consumption rate and a tentative fuel consumption rate are repeatedly acquired from an air-conditioning apparatus. The tentative fuel consumption rate is a fuel consumption amount per unit time to generate a power consumed under a post-offset preset temperature being different from a present temperature by an offset temperature. Based on the acquired actual fuel consumption rate and the acquired tentative fuel consumption rate, an actual fuel consumption accumulation amount and a tentative fuel consumption accumulation amount are calculated in the same record period and are recorded as a data set in a travel history database. Then, several data sets recorded over the several record periods are read out from the travel history database. The total of the actual fuel consumption accumulation amounts and the total of the tentative fuel consumption accumulation amounts over the read several data sets are notified.

摘要： When an accelerator is put in an OFF state to decelerate a vehicle and perform inertia travel with supply of fuel being cut off, measurement of an accelerator OFF lapse time is started. When a travel speed falls down to be lower than a pre-stop speed, a measured lapse time is stored in a memory, with the measurement of the lapse time being further continued. After finishing a travel of a downward slope, the travel speed is reduced to fall down to the pre-stop speed again, a lapse time continuously measured up to that time is updated in the memory. When the travel speed falls to a stop speed, the measurement of the lapse time is finished and the continuously-measured lapse time is determined as a required stop time of the vehicle. As the required stop time increases, driving is diagnosed as being fuel-efficient.
