摘要： PURPOSE:To diagnose satisfactorily I/O conditions by transferring I/O units conditions stored in a status register to a diagnosis control circuit and comparing them with status information in a status table when an electronic circuit is switched to a test mode. CONSTITUTION:When a test mode change-over switch 9 is switched to the test mode, a microprogram for diagnosing in a ROM 6 is executed, thus, a status table 12 containing the information corresponding to respective I/O units 3-5 is provided, it consists of the ROM and the defective of a tested circuit is beforehand stored in it as the status information. Consequently, the comparing those transferred from the respective I/O units 3-5 with the information in the table 12, the presence or absence of defects in the I/O units 3-5 is decided. As the result, the codes of devices stored in the status registers of the I/O units 3-5 are referred, the position of a defective device is detected and displayed outside through a displaying interface 10.

摘要： PURPOSE:To make possible the approach of the square billet to be stably guided, by arranging the stationary guide for bearing the adjoining two planes of the square billet and the flexible, movable guide for bearing other two planes, in the approach guide for the square billet. CONSTITUTION:The stationary guides 13, are attached to the frame 12 of L-type section in order to bear the bottom plane lowering its temperature faster than other planes, and to bear one side plane; the movable guides 16, are attached to the frame 14 of L-type section through the coil spring 15, for bearing other two planes keeping higher temperatures than other planes. The center of the billet 1 displaces from A-B owing to the pressure of the press machine. The center of the piercing plug is located so as to point A; however, the piercing plug pierces the billet moving toward the interior of the billet being held at higher temperatures and showing less resistance force; hereby, the eccentricity of thus prepared hollow blank pipe becomes small. And then, the square billet 1 with enlarged sectional area is smoothly guided into the hot piercing plant.

摘要： PURPOSE:To obtain a tester which facilitates detection of a defective part, by connecting a unit for testing having a function equivalent to a unit to be tested as well as a diagnosing device to implement tests for a modem circuit and overall function. CONSTITUTION:A unit 1 to be tested is connected to a unit 2 for testing a test system of a data communication unit and a diagnosing device 3. In the diagnosing device 3, a control section 5 and a test module section 4 are connected to the unit 1 being tested and the unit 2 for testing through a test interface 6 to control. The unit 2 for testing has a function equivalent to the unit being tested to perform an opposed test more than equal to a system test and a test diagnosis for the whole of a unit. This enables the production of a test for a data communication electronic unit which facilitates detection of a defective part with a reduction in the weight of the system test.

摘要： PURPOSE:To manage the original effectively by printing the orginal serial number on the transmitting original by the provision of the printing printer for the end of the original on the transmission device. CONSTITUTION:When the end of the transmission original 1 passes through the original reading device 9 in the vicinity of the feed roller 5, the command from the external portion is received to stop the original temporarily. Then, the printer 10 is operated and the printing character is transferred on the original 1 and the feed rollers 5, 6, 7, 8 are rotated to discharge the original 1 out of the device. The printing character drum in the external frame of the printer is placed on the upper side of the original 1 and is shaped in a cylindrical figure in which a plurality of discs are superposed one upon another, as a whole and the letters or numerals are disposed in opposition to the form, on the peripheral portion thereof and rotated by the rotating axis 15. The transfer hammer 16 in the external frame contacts the outer circumference of the cam 18 by the spring 17 and the cam 18 rotates centering the rotary axis 19. The solenoid supporting stand 21 is a fulcrum of the circular movement of the stopper 20 to support the solenoid 22. According to such a construction, the printing can be done without requiring the man labour.

摘要： PURPOSE:To make a mill capable of having a large crown or shape controlling capability by providing an interposing block which moves vertically with a roll chock and making the block vertically movable through a shifting frame. CONSTITUTION:For a rolling material with large sheet thickness, a roll chock 15 of a backup roll 13 is lifted through a lifting arm 18, and an interposing block 19 is also lifted by the chock 15. In this case, because a roll chock 16 of an upper roll 14 is lifted together with the block 19, there causes no special change in the positional relation between the chock 16 and the block 19 which supports the chock 16 through hydraulic cylinders 21. Accordingly, a roll bending work is sufficiently performed without being influenced by the change of the height of work roll 14 even when the roll 14 is largely opened.
摘要翻译：目的：通过提供一个用滚动轴承座垂直移动的插入块，并使块可以通过移动框架垂直移动，来制造能够具有大的表冠或形状控制能力的磨机。构成：对于具有大板厚度的轧制材料，支承辊13的辊轴承座15通过提升臂18提升，并且插入块19也被轴承座15提升。在这种情况下，因为辊轴承座16 上辊14与块体19一起被提起，通过液压缸21不会使轴承座16与支承轴承座16的块19之间的位置关系发生特殊的变化。因此，在没有即使当辊14大幅打开时，也受到工作辊14的高度变化的影响。
