Title: Appratus for detecting breakage of a tool
Inventor: YOSHIMI TAKAHITO
IPC: B23Q17/09
Filed: 1977-11-09
Abstract: PURPOSE:To detect the breakage of a tool during tool charge and to eliminate a loss time only by linearly moving ahead a detection head to a detection site by use of a rising motion of a socket which is a necessary motion of a tool-storage magazine. CONSTITUTION:If a tool 7d with a minimum rank of length is restored in a horizontally lied socket so as to start rising motion, a cylinder 18 for moving a detection head back and forth is actuated at the same time according to instructions for detecting the breakage of the tool 7d. A detection head 16 which moves ahead by receiving the instructions stops by the motion of a dog 23d for tool 7d detection side use that beats a limit switch 22d for tool 7d detection site confirmation use. At the stop position, an operator of a limit switch 24d for tool 7d detection use positions on a locus of the normal length head of the tool 7d at rising. If the tool is broken, the operator does not come into contact with the tool head, and generating an NG signal.

Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To realize a defective junction detecting method, which can accurately detect a defective location in a p-n junction in a semiconductor device and can avoid etching of an impurity inlet region by the defective detection. SOLUTION: A positive terminal of a D.C. voltage source 6 is connected to an n-type silicon substrate 2, having a p-type impurity introduction region 4 having lattice-like element isolation regions 3 isolated therefrom in its surface, a negative terminal of the voltage source 6 is connected to a counter electrode 8, and then the connected substrate is immersed into a chemical etchant 7 which can etch and electrolyze silicon. A reverse bias characteristic of a p-n junction is invalidated, so that a positive potential of the power source 6 is transmitted to a p-type impurity inlet region 4a having a defect 5 therein causing a junction failure such those, ending up in conduction of both. An oxide film is formed through electrolysis on a surface of the region to prevent advancement of etching.  Meanwhile, since the surface of the region 4 other than this is etched, the defective junction location can be detected accurately.

Title: Semiconductor integrated circuit device
Inventor: OKAMURA HITOSHI
IPC: G11C7/00
Filed: 1994-06-16
Abstract: PURPOSE:To provide a semiconductor integrated circuit device which can reduce power consumption while keeping its high speed operation by correcting the high level of a next-stage drive signal into a low potential level lower than a high power potential toy a degree equal to the threshold voltage or a MOS transistor TR and then supplying the drive signal of a corrected level to a circuit of the next stage. CONSTITUTION:A next-stage drive signal NDVx is set at Vcc (the base-emitter voltage of a bipolar TR Th1) while an input signal IN changes to a low level from a high level. Under such conditions, the MOS TR Tm4 and Tm5 are turned on and therefore the potential of a corrected next-stage drive signal NDV rises higher. However the Tm4 is turned off when the signal NDV is set at a prescribed potential since the signal NDV is supplied to the gate of the Tm4. Thus the supply of a charging current is discontinued to a circuit 2 of the next stage. As a result, a MOS TR Tm11 is turned off so that the leak current due to the Tm11 can be eliminated. Furthermore the amplitude of the signal NDV is minimized and the power consumption is reduced.

After that, 1,10-phenanthroline is added. A complex of divalent iron ions and the 1,10-phenanthroline is generated. The complex is extracted by a mixed solvent which is composed of at least two kinds of organic solvents. The absorbance of its extract in a prescribed wavelength region is measured by an absorptiometric method.  Therefore, the amount of the complex of the divalent iron ions and the 1,10-phenanthroline is measured, and the amount of the trivalent titanium ions is found on the basis of its measured result.
