Title: Lighting device for electric discharge lamp
Inventor: YAMAMOTO SUSUMU
IPC: H05B41/282
Filed: 1994-08-09
Abstract: PURPOSE:To stably retain a lighting state even when power voltage is decreased down to below discharge voltage for an electric discharge lamp by increasing a preheating frequency on detecting a decrease in voltage and by activating thermionic emission from the electric discharge lamp. CONSTITUTION:A voltage decrease detecting circuit 31 is operated when DC output voltage VDC from an AC/DC inverting circuit 8 is decreased to around discharge voltage for an electric discharge lamp 9. A resistor R32 is connected in parallel with a resistor R26b on a preheating timer circuit 26 to decrease charging voltage for a capacitor C26. A transistor Tr26 on the circuit 26 is, therefore, lead to an off state to set collector voltage to VDC, resulting in sending operating instructions 26S to a preheating frequency switching circuit 24, and increasing the entire light-lighting frequency of a modulated light controlling circuit 20S to preheating frequency. Thus flickering due to a decrease in voltage or troubles due to lights-off are eliminated to stably retain lighting by switching an oscillating frequency to the preheating frequency through the preheating timer circuit on decreasing power voltage and by activating thermoelectron emission from an electric discharge lamp.

Title: Building equipped with vibration control device for wind
Inventor: TACHIBANA EIZABURO
IPC: E04H9/14
Filed: 1994-08-09
Abstract: PURPOSE:To use small energy in controlling the horizontal vibration of a building caused by wind by using a control portion in controlling the rotation of a movable vane installed at the uppermost story of a building, and varying the face area of the movable vane in the direction of the wind according to signals from sensors. CONSTITUTION:States such as the direction and speed of the wind and vibrations are input to a control portion 4 from sensors such as an anemoscope and an anemometer 9 at the uppermost story of a building 1 and a speed-type seismograph 10 on a predetermined story. The control portion 4 calculates the rotation angle of a movable vane 3 as to the direction of rotation on the basis of the quantities of those states so that the movable vane 3 has the appropriate face area in the direction of the wind. A servo motor is rotated to rotate the movable vane 3 in the direction in which vibration control for the building 1 is most expected. Thus when the building 1 vibrates in the direction of action of the wind, the movable vane 3 is rotated in a direction perpendicular to the wind to maximize the force of wind pressure. Alternatively, the movable vane 3 is rotated parallel to the wind to increase or reduce the wind pressure force to control vibrations generated in the building 1. Therefore, vibrations generated in the building 1 in the direction of action of the wind can be reduced by use of the wind.
