摘要： PURPOSE:To lower the price of a display part by embedding no LED chip in dot LED units of display unnecessary parts and thus forming empty units. CONSTITUTION:The empty units 4'' determine illumination positions so that the number of embedded units is maximum. If an LED chip becomes faulty, the relative positions of a symbol plate 5 and a dot LED display unit 2 are moved right or left, or up or down to switch the faulty chip 2 to a normal LED chip, thereby using the panel continuously. The number of the empty units is determined in consideration of even the shift in the relative caused by the faulty LED chip. Further, the embedding positions of the empty units can be specified optionally. The empty units are lower in price than the real units, so the price of the dot LED display unit 2 is reducible and the price of a monitor board 1 is also reducible.

摘要： PURPOSE: To ensure the security by setting up fixing metal fittings in both of bottom of CPU box and the bed, and connecting and fixing the two fixing fittings with connecting metal fittings while fixing them. CONSTITUTION: A caster 3 and upper fixing metal fittings 10 are set up on bottom of a CPU box 2, lower metal fittings 11 are arranged in bedsurface 5. While fixing the CPU box 2, the upper fixing metal fittings 10 and the lower fixing metal fittings 11 are connected with connecting metal fittings 12. Therefore, as the CPU box is surely fixed with the bed 5, the CPU box does not move or fall off even if an earthquake, the security is ensured.

摘要： PURPOSE:To prevent operator's sleep from being disturbed, by forcibly stopping a fan in the time zone when he falls asleep and controlling turn-on/off of the fan at a low speed in accordance with the temperature in a board in the time zone of sleep following the time zone. CONSTITUTION:A period (b) from a time T2 to a time T3 at night is the time zone when the operator falls asleep. When a forcibly turning-off command 12 (in the high level) is outputted from a schedule generator 3, a control line 15 is set to the low level, therefore, outputs (control lines 17 and 19) of AND elements 7 and 10 go to the low level, and an operation relay 52 and a low- speed operation relay 42 are inactivated to stop a cooling fan 1, then, the operator can fall asleep because the noise is not generated. A period (c) from the time T3 to a time T1 is the time zone of sleep, and the schedule generator 3 does not output a turning-on command neither the forcibly turning-off command then. Therefore, turn-on/off of the cooling fan is automatically controlled in accordance with the detection temperature of a temperature sensor 4.

摘要： PURPOSE:To continue the use of a display device when a dot LED chip fails without replacing the display device, and prolong the apparent life to minimize costs by rotating the dot LED display device by 90 degrees to the position at which the chip is not used. CONSTITUTION:With a dot LED display device 4, its mounting screw positions 10 and the positions of dot LED chips are arranged in squares, and (a), (b),... and A, B,... are regarded as software addresses. LEDs being in use are indicated by black circles, and it is assumed that B in column (b), and D in column (b) are in use, and B in column (b) fails. When the display 4 is rotated 90 degrees, B in column (b) is moved to a software position B in column (e); when the device is rotated 180 degrees, B in column (b) is moved to E in column (e); when the device is rotated 270 degrees, B in column (b) is moved to E in column (b). At the three positions countermeasures can be taken to prolong the apparent life of the device substantially. At this time, it is necessary, simultaneously, that an IC memory card of a microcomputer for controlling the display device is replaced by another one for a new dot, but the display device can be restored to the normal condition in a short time and at minimum costs compared to replacement of the device.

摘要： PURPOSE:To form a long life graphic panel by moving a failed dot LED chip by a dot pitch in parallel and replacing an IC memory card for a display device controlling microcomputer by the one for a new dot. CONSTITUTION:A simply plate 5 is fixedly assembled on a monitoring board frame 7. A dot LED display device 2 can be vertically and horizontally centered by a centering adjusting volt 9 to set up its relative position to a symbol plate 5 and its position is fixed by a locking nut 10. When a dot LED chip is turned off due to its fault, the dot display device 2 is moved to a position on which the OFF dot LED chip is not used only by the dot pitch in parallel by the bolt 9 and the locking nut 10 and the old IC memory card 18 is replaced by a new one. Thereby, the graphic panel can be immediately restored without replacing the dot LED display device 2 or repairing it.
