摘要： PURPOSE:To maintain specified polishing pressure by the constitution consisting in supporting a rotary polishing plate for electrode polishing to an air cylinder for raising the polishing plate by polishing pressure generating springs. CONSTITUTION:The air cylinder 11 is actuated to raise a movable rod 11a and while the rotary polishing plate 19 is rotated, an upper electrode 22 is lowered. The compressing size of the springs 20, 21 is always constant and therefore the specified polishing pressure is generated if the stroke of the cylin der 11 and the stroke of the electrode 22 are kept constant during this time. The electrode 22 is thus polished by the plate 19 always under the specified pressure. The polishing pressure, if desired to be changed, is easily adjusted by changing the stroke of the cylinder 11 or the electrode 22.

摘要： PURPOSE:To test a highly integrated circuit precisely by providing an emitter coupling type logical circuit (ECL) with a test circuit to control the ECL by a logical signal level from the external independently of an input signal to the ECL and set up the output of the ECL to the level corresponding to zero of the logical signal. CONSTITUTION:A transistor (TR) T6 is connected to the base circuit of a TR T4 of an OR output circuit and a TR T7 is connected to the base circuit of a TR T5 of a NOR output circuit. When a signal ''1'' is applied to a test terminal, the TRs T6, T7 are connected and the base potential of the TRs T4, T5 is shifted to the negative side, so that the base potential of the TRs T4, T5 are reduced and both the OR and NOR output terminals are turned to ''0''. Since said operation is not restricted by the operation of the Trs T1, T2, T3, the operation has no relation to the input conditions and there is no electrical bad influences to the original circuit.

摘要： PURPOSE:To avoid hazard at an output termial, by providing another input terminal to a gate casuing hazard for the output and supplying a preset signal, when a clock pulse is applied to a D type edge trigger FF circuit. CONSTITUTION:Another terminal is provided at an NAND gate 3 of an FF circuit and this is connected to a preset terminal 7. When a terminal 7 and a clear terminal 8 are respectively ''high'' and clock terminal 9 and data terminal 10 are respectively ''low'', a terminal 11 is ''low'', terminals 12-14 are ''high'', output terminal 15 is ''low'' and output terminal 16 is ''high''. When the terminal 7 changes from ''high'' to ''low'', the terminal 11 changes from ''low'' to ''high'', and the terminal changes from ''low'' to ''high'' and the terminal 16 changes from ''high'' to ''low''. When a clock pulse is applied to the terminal 9, since a signal of ''low'' is supplied from the terminal 7 to the gate 3 terminal of the terminal 13, no change is made from the delay time of gate one stage's share in the state of ''high'' to ''low'', no hazard is caused to the terminal 13 to be a constant level, and no hazard is caused to the terminal 16.

When a pinion 15 is driven to pivot by the motor of a drive 14 provided to the side of a prism 10 of the movable base 2, the movable base 2 can be made to move freely in a horizontal direction to the fixed base 1. At this point, the rack supporting device is formed in such a telescopic structure or a shrinkable structure that the prism 10 is telescoped into a square pillar 6, the overall length of the device can be reduced to an irreducible minimum corresponding to the overall length of the rack 5. The supporting piece 3 is composed of a slide 20 movable in a vertical direction and a rotary part 21 supported by the slide 20 in a freely pivotable manner.
