Patent JP-H01232396-A (JP)
Title: Display device
Inventor: OKURA TOSHIYA
IPC: G09G3/06
Filed: 1988-03-11
Abstract: PURPOSE:To prevent the secondary harzard of an electric shock on man by disposing a conductor which crosses a panel substrate and constituting the device that the conductor is cut when the panel is broken during the operation of the display device thereby rapidly turning off the power supply to a switching element. CONSTITUTION:The conductor 2 is provided by screen printing, etc., on a display panel 1. One end of the conductor is grounded and the other end is connected to the switching element 9. The voltage of a DC/DC converter 4 is supplied through pulse generating circuits 5, 6 which generate high-voltage pulses of antiphases to matrix driving circuits 7, 8. The input to the switching element 9 is released from the grounding state and the switching element 9 is turned off when the conductor 2 is cut by the failure of the display panel 1. The high- voltage supply to the panel generating circuits 5, 6 is then rapidly interrupted. The secondary harzard of the electric shock is thus prevented even if the electrode, etc., of the broken display panel 1 are touched.

Filed: 1987-03-14
Abstract: PURPOSE:To bring the capacity of a smoothing capacitor to the capacity of a normal smoothing capacitor by driving an inverter circuit while being synchronized with the revolution of a motor on the recovery of service power of instantaneous service interruption. CONSTITUTION:A power supply is fed after instantaneous service interruption while a control circuit 7 drives an inverter circuit 3 as the control circuit 7 is synchronized with the revolution of a motor 4. Consequently, the so-called tripping phenomenon of the motor 4 due to the asynchronism of the revolution of the motor 4 and an output from the inverter circuit 3 is prevented. Accordingly, since the motor 4 is turned by inertia during instantaneous service interruption, the capacity of a smoothing capacitor C1 need not be increased, thus reducing the capacity of the smoothing capacitor C1.

Abstract: PROBLEM TO BE SOLVED: To prevent a concentrated load from applying to the opening region of a drilled hole by a method wherein the intervals between a pair of cutting elements adjacent to each other on the side approaching to an installing end part are made wider than the intervals between a pair of cutting elements adjacent to each other on the side separating from the installing end part. SOLUTION: The intervals A2 , A3 ...A(N-1) and AN between a pair of cutting elements 25 adjacent to each other on the side approaching to an installing end part 23 are made wider than the intervals A1 , A2 , A3 ...A(N-1) between a pair of the cutting elements 25 adjacent to each other in the side separating from the installing end part 23. The intervals A1 , A2 , A3 ...A(N-1) and AN depend on the magnitude of the tensile load to load, the depth of a drilling hole 26, the strength of the bedrock U, in which the drilling hole 26 is formed and the like. Thus, the greater part of the tensile load applying to an anchor rod is surely transmitted through adhesive to the bedrock U at the region near the bottom part of the drilled hole 26.
