Abstract: A hydrogen production supply system that produces hydrogen gas to be supplied to a hydrogen storage tank, the hydrogen production supply system including a control circuit configured to control an operation load ratio of the hydrogen production apparatus to a predetermined operation load ratio, to increase the operation load ratio of the hydrogen production apparatus to a first operation load ratio larger than the predetermined operation load ratio at first timing, and to decrease the operation load ratio of the hydrogen production apparatus to the predetermined operation load ratio from the first load operation ratio at second timing, wherein an increase in the operation load ratio at the first timing takes precedence over a decrease in the operation load ratio at the second timing.

Abstract: An operation method is provided for a hydrogen production apparatus that is disposed in a hydrogen station and produces hydrogen gas to be supplied to a fuel cell vehicle (FCV) arriving at the hydrogen station. The operation method includes starting up a hydrogen production apparatus up to a first operation load ratio preset for a rated operation. The operation method includes increasing an operation load of the hydrogen production apparatus to a second operation load ratio, which is larger than the first operation load ratio, at first timing associated with an arrival of the FCV, and decreasing the operation load of the hydrogen production apparatus to a third operation load ratio, which is smaller than the second operation load ratio, at second timing associated with a completion of hydrogen filling into the FCV.

Abstract: A self-illuminant delineator including a plurality of light-emitting diodes being flickerably disposed on the sign surface of the delineator and covered by a transparent cover, a solar cell module being disposed on the top surface of the delineator and covered with a transparent cover, a transmission means and/or a receiving means for a signal which controls the flickering of the light-emitting diodes. Also a self-illuminant delineator system including a plurality of the above self-illuminant delineators which are installed to form a line-up of an eye-guiding, traffic or other sign along a shoulder of a road.

Abstract: The present invention relates to a solar cell module comprising a projected section formed on a side of a module case including plural interconnected solar cell devices, a groove section formed on the opposite side to accommodate the projected section and terminals of the solar cell devices, which are provided on the projected section and the groove section so that the plural solar cell modules can be connected mechanically and electrically, whereby the first-engagement sections provided on the projected section of a module case are inserted into the second-engagement sections provided on the groove section of another module case so that plural module cases can be connected easily and securely to each other at the regular position.

Abstract: A lighting equipment adapted for outdoor location, the equipment being supported on a structure on which a solar cell is placed to charge up a battery for lighting a lamp, wherein the battery and the lamp are provided in the structure, the lamp being lit from the sunset up to the expiry of a predetermined period of time.
