Title: Solar battery type signboard
Inventor: YAMAGUCHI MASAHIDE
IPC: H01L31/04
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a solar battery type signboard allowing a solar battery and a storage battery to do with smaller capacity. SOLUTION: A normally-open switch 7 is arranged in the line connecting between a storage battery 3 and an electric display board 4, and the switch 7 is controlled on-off by a noise discrimination circuit 6 with a microphone 5. When a train is approaching to the electric display board 4 at night, the noise of the train is taken in the noise discrimination circuit 6 via the microphone 5, and when this detection signal satisfies prescribed conditions, the noise discrimination circuit 6 makes the switch 7 on to turn on the electric display board 4. Then, when the train goes away, the switch 7 is brought into off-state to turn off the electric display board 4. In such a manner, it is possible to avoid wasting unnecessary power consumption of the signboard during the night, and reduce capacities of the solar battery and storage battery compared with those of conventional ones.

Title: Printer having print head capable of simultaneously printing plural lines and method for controlling the same
Inventor: TERADAIRA MITSUAKI
IPC: G06F3/12
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To improve a printing speed for printing of print data of which the number of printing lines is not greater than that of maximum printable lines in terms of a printer having a print head capable of simultaneously performing the printing of plural lines. SOLUTION: Print data sequentially transmitted from a host device is developed in a plurality of print buffers for storing binary information for driving plural lines of printing elements. The print buffer is in a state of developing while each line of binary information is developed and becomes in a printable state when the developing is completed. While the printing of the data in the print buffer is being executed, the buffer is in a state of printing and becomes in a printing completion state when printing is completed. As the printing operation is initiated when the print data in the first line is developed, a waiting time for waiting the printing start can be reduced and the developing operation and printing operation can be concurrently executed, thereby improving the printing speed.
