摘要： PROBLEM TO BE SOLVED: To extract an electronic-level fixed fault between an electronic computer and plural peripheral equipment or between the electronic computer and plural peripheral equipment connected through a repeater driver for converting the electronic level or the like and to correctly indicate a fault portion. SOLUTION: When an electronic computer 10 or fault detection means (14, 31, 41 and 51) inside each peripheral equipment (30, 40 and 50) detects faulty, each peripheral equipment (30, 40 and 50), the electronic level fixed interruption of the peripheral equipment and the repeater driver is extracted by reading out each of particular device numbers provided with a repeater driver 20 and read-out dedicated registers (22, 32, 42 and 52) showing the inverse pattern of the device numbers by the electronic computer and executing a confirmation of high level/low level of all bits. Since the device numbers are particular values respectively, it is possible to indicate which peripheral equipment or repeater driver is a fault occurrence portion.

摘要： PURPOSE:To decrease turbulent noise by providing a suction port in a pressure surface in a side of a trailing edge of a blade, blowout port in the trailing edge and a flow path, for both the suction and blowout ports to communicate, in the inside of the blade. CONSTITUTION:A blade 2 provides a suction port 7 in a pressure surface 5 in a side of a blade trailing edge, blowout port 8 in the vicinity of the trailing edge and a flow path 9, through which both the ports 7, 8 communicate, in the inside of the blade 2. In this way, since a growth of turbulence from a free turbulent shear flow in the trailing edge of the blade can be reduced,, turbulent noise decreases.

摘要： PURPOSE:To reduce a noise in simple construction by installing a guide piece in such a manner that one end of said guide piece may be fixed to an air duct wall surface and the other end of the guide piece may be slantingly lifted in the direction of an air flow and the tip of said other end of the guide piece may be positioned to face an outer periphery of a blade located where a maximum negative pressure of said blade exists. CONSTITUTION:A guide piece 8 is installed to an air duct wall surface 4 inside an exterior box 2 in such a manner that it may be formed, extending in an opening direction to said wall surface, one end of the guide may be fixed to said wall surface, the other end may be lifted in a direction slanting to the suction air flow, the tip position of the other side may be opposed to the outer periphery section of a blade 5a of a propeller fan 5 in a position slightly forward than the rear end position of a heat exchanger 1 installed axially to the outer periphery section of the blade 5a of the propeller fan 5. Therefore, the air sucked-in flows smoothly into the blade as indicated in the arrow A without producing any breaking away whirl, and is smoothly led into the maximum negative pressure suction under the guide of the guide piece, thereby producing no noise without any interference with the tip whirl.

摘要： PURPOSE:To make a noise of an outdoor unit low by a method wherein supporting elements at a shaft constitute a supporting member for enclosing a fan motor in symmetrical with a center of the shaft, annular vibration-proof rubbers are fixed to both side surfaces near the center of shaft of the fan motor and their outer circumferences are indirectly supported to a protective guard. CONSTITUTION:An outer casing 1 has a protective guard 2 at a substantial central part of a longitudinal surface, a front supporting part 2a for a fan motor is arranged at a central front part, its central part is projected further forwardly, an annular vibration-proof rubber 4a is inserted in it and a front end of the fan motor 3 is set in coaxial with the center of the shaft. A rear supporting part 5 is projected rearwardly so as to enclose an outer circumference of the fan motor 3, its central part is projected rearwardly and an annular vibration-proof rubber 4b is inserted into a rear part of the fan motor so as to support it at the center of the shaft. A propeller fan 8 is located for rearwardly than the fan motor 3, an inner side of a central hub 8a may enclose an outside part of the rear supporting part 5 in a spaced-apart relation and rotatably arranged. Accordingly, an amount of vibration transmitted to the protective guard 2b is reduced, vibration of the outer casing 1 is also reduced and a circulating vibration of the fan motor can be reduced.

摘要： PURPOSE:To reduce the number of program steps, by storing the result of zero checking of the result value of a logical operation other than the logical operation indicated clearly by a program. CONSTITUTION:When the exclusive OR operation of data in a work register (WR)6 and a literal value in a control storage data register (CSDR)2 is performed at a logical operation circuit 9 having an EOR function, an arithmetic result is set at the WR6 via an arithmetic result register 16. At this time, a decided result of all '0's that is the arithmetic result of the exclusive OR operation is set at an FF19, and also, the arithmetic result of a logical product not being indicated in the program, and the decided result of all '0's that is, the arithmetic result of the data in which an input data on one side is inverted, are set respectively at the FF18 and 19. Therefore, it can be said that plural logical operations are performed simultaneously from the standpoint of the program.

摘要： PURPOSE:To make a channel command language processing highly speedy by converting a channel command language read from the memory device to the prescribed shape in accordance with the shape classification and unifying and processing to a constant shape channel command language. CONSTITUTION:When a microprogram requests the access to a main memory device with an access request signal 230 as '1', signals 231 and 232 following said signal becomes both '1' and then, a flip-flop (FF) 202 goes to be '1' and stores that the reading of the channel command language of a shape '0' is requested. A main memory device to receive an access request signal, when its action is completed, informs of the action completion with a signal 250 as '1', and records the reading data to lines 240-247. Said data are transferred through an FF 203, an inverting circuit 204, AND circuits 251-267 and OR circuits 271-277 to registers 220-270 respectively, thereby the data are converted into the channel command language of the shape 1.

摘要： PURPOSE:To increase a processing speed and reduce the capacity of a control storage by reading successively micro instructions from the control storage while using contents of a selected program address register as read addresses and executing these micro instructions. CONSTITUTION:Program address registers 2 store read addresses of control storage 3 where a micro program is stored and are equipped correspondingly to respective channels, and one of registers 2 is selected according to contents of channel address register 1 which stores temporarily an interrupt channel number. Contents of selected register 2 are used as read addresses to read successively micro instructions from control storage 3 and execute these micro instructions, and simultaneously, contents of selected register 2 are updated to execute the interrupt processing of the interrupt chanel. As a result, the processing speed can be increased, and the capacity of control storage 3 can be reduced.
