Abstract: PURPOSE:To obtain a non-magnetic or weak-magnetic diamond sintered compact with low magnetic susceptibility by providing a sintered compact which is composed essentially of diamond having specified grain size and in which binding phase is composed of metallic components containing ferromagnetic iron- group metals and weak-magnetic metals in specific proportions. CONSTITUTION:In a high hardness sintered compact containing >=50vol.% diamond having 0.1-100mum grain size, its binding phase is essentially composed of iron-group metals. This binding phase is formed by allowing 1-50% of weak- magnetic metallic components having <=5X10<-6> (eum/g) magnetic susceptibility, such as Cr, V, Cu, Si, Zn, Al, Mo, and W, to form a solid solution in ferromagnetic irongroup metals, such as Ni, Co, and Fe and performing alloying. By the above procedure, the magnetic moment of the diamond sintered compact composed essentially of iron-group metals is reduced by >=80%, and magnetic susceptibility is regulated to <=3% of that of Fe. This sintered compact is obtained by mixing binding phase metal component, finer-grained than a diamond powder as a principal component, with this diamond powder and then sintering the resulting mixture under the diamond stability region.

Title: Information processing device

IPC: G06F12/08
Filed: 1979-11-08
Abstract: PURPOSE: To improve the bit rate of the buffer memory to improve the processing efficiency, by lowering the number of times where contents of the buffer memory are made ineffective in the information processing device having the high-speed buffer memory.  
     CONSTITUTION: Comparator 23 compares memory contents change time 12 with contents of register 21, which indicates the time when buffer memory 3 incorporated in the assigned processor was made ineffective at last, with each other. If said time 21 is later than said time 12, memory contents were changed after contents of the buffer memory were ineffective, and it is probable that contents disagreeing those of the main memory device are left partially in the buffer memory, and the buffer ineffective signal is generated. If time 21 is earlier than said time 12, contents of the buffer memory were made ineffective after memory contents were changed, and no ineffective signal is generated. As a result, the bit rate of the buffer memory is improved to improve the processing efficiency by lowering the number of times where the buffer memory is made ineffective.

Title: Method of compensating temperature dependency of output signal
Inventor: JIYAAN MISHIERU MOROO
IPC: H03B5/04
Filed: 1990-06-01
Abstract: PURPOSE: To eliminate the effect of temperature variation by using the temperature variation as a function of a specific temperature for the AC current of the conductive material of an oscillation coil supplying a correction signal thereby making possible to use as a proximity detector. CONSTITUTION: The circuit comprises an AC current source of constant amplitude IB connected between first and second constant voltages M, VCC and the current flows through an oscillation circuit comprising a capacitance C and an inductance L corresponding to the coil of a proximity detector. When a DC current passes through series windings L, L', a DC current flows between the potential VCC and V1 . Substantially no AC current is present between the potential VCC and V1 when the DC current passes through series windings L, L', because of high coupling value between the windings L, L'. Consequently, the ends of the windings L, L' can be interconnected through an arbitrary capacitor C1 of appropriate value in order to avoid generation of any AC parasitic voltage.  Variation of DC resistance in the windings L, L' can thereby be used for compensating for the temperature fluctuation of the signal on a terminal E.
