摘要:
It is an object to provide a method of sorting semiconductor lasers, capable of appropriately removing semiconductor lasers which can cause a so-called sudden death in use. After a first current within a range of 50 to 150% the maximum rated current is supplied to the semiconductor lasers for a predetermined period of time, a second current is supplied within a range of 120 to 250% the maximum rated current for a short period of time. Semiconductor lasers which are destroyed or degraded in output characteristics are removed as defective devices.

摘要:
A power transmission reception system for pairing a charge-requesting vehicle with a discharge-requesting vehicle for power transmission reception therebetween includes an extraction device and a transmitter. From each vehicle, a center acquire information about a present location, a traveling direction, and a destination point, and records the acquired information in a database while classifying the vehicle as the charge-requesting vehicle or the discharge-requesting vehicle. The extraction device extracts the charge-requesting vehicle and the discharge-requesting vehicle that are to simultaneously travel in a same area as paired vehicles in accordance with the information in the database. The transmitter generates information about a power transmission reception area and a partner vehicle in the power transmission reception, and transmits the generated information to the paired vehicles.

摘要:
A manual operation device of the present disclosure allows a user to intuitively recognize a force pattern by providing a graphical representation of the force pattern on a display unit. The force pattern or a relationship between an operation position an operation unit of the manual operation device and a control value is visually represented as, for example, a two-dimensional line graph. In this manner, the reaction force is suitably adjusted to an operation force of the user to reduce an false operation of the manual operation device, because the user can easily controls the reaction force for achieving an improved operability.
