Abstract: PURPOSE:To utilize existent facilities by arranging many light emission bodies on the external surface of an outdoor advertisement facility at constant intervals in a matrix, connecting the light emission bodies in the advertisement facility, and connecting a driving device for turning on the light emission bodies selectively. CONSTITUTION:This device makes an electrooptic display on an advertisement tower 10 in the nighttime. Characters 'SAM ELECTRONICS' for advertisement are displayed on the external surface 12 of the advertisement tower 10. Many light emission bodies 14 are arranged on the external surface 12 of the advertisement tower 10 in the matrix and emit light forward on the external surface 12 with relatively large directivity. Thus, the emission direction of the light is made directional not to irradiate the external surface 12 of the advertisement tower 10 when the electrooptic display board is used in the nighttime. Plural LEDs 20 ... which differ in color are fitted in one socket 16. The specification of the illumination quantity and colors of the LEDs 20 ...is controlled by the driving device. In the nighttime, the external surface 12 is not seen, so the pattern of the external surface 12 is unnecessary. Therefore, when the driving device 18 is put in operation, characters, symbols, etc., which are completely irrelevant to the external surface 12 are displayed electronically.

Title: Power supply device
Inventor: KOMATSU SHUNICHI
IPC: H02M3/28
Filed: 1990-09-17
Abstract: PURPOSE:To prevent the breaking of a switching control IC for a DC-DC converter by detecting the reduction of the difference of input-output voltage to a fixed value or less. CONSTITUTION:When a primary-side current limiter by a switching transistor Tr11 and a resistor R11 is operated, the voltage of Vin(IC) itself begins to drop. Consequently, when load is further short-circuited gradually, Vin(IC) is brought near to Vout1, and the difference of Vin(IC) and Vout1 is reduced to a certain fixed value or less. That is, the Zener voltage of a Zener diode ZD101 is set at a value slightly higher than the difference of input-output voltage to be ensured at that time, and the division ratio of resistors R101, R102 and the division ratio of resistors R14, R15 are equalized previously. The voltage of an input and an output is input previously to an amplifier 101. When the difference of Vin(IC) and Vout1 are equalized to Zener voltage VZD101, an output from the amplifier 101 is inverted to a negative value, and PWM pulse width input to the base of a power transistor Tr12 is narrowed, thus protecting the IC.
