Title: Single electron tunnel logical element
Inventor: HIGURE HITOSHI
IPC: H01L29/06
Filed: 1995-03-14
Abstract: PURPOSE:To obtain a stable output against input variation. CONSTITUTION:The element is produced with a channel formation circuit in which impedance elements 1 and 2 having respectively single electron tunnel connections are serially connected with each other. When the respective tunnel resistances of the elements 1 and 2 are R1 and R2 and the connection capacitances are C1 and C2, R1>R2 and C1>=C2 or R1<R2 and C1<=C2 are satisfied. Thus, the accumulation charge for an island part 4 is quantized almost integer-fold of 'e' against the input voltage, and the current voltage characteristic shows a Coulomb stair case, further a Coulomb oscillation characteristic with square waveform can be obtained. Then constant output current values against the constant input voltage width can be obtained, thereby making a margin of voltage value corresponding to the respective input logical levels to be larger. Therefore, the output against input variation can be obtained stably.

Title: Ball joint
IPC: F16C11/06
Filed: 1992-03-13
Abstract: PURPOSE:To improve seizure resistance and also to prevent generation of an inflection point, which is a cause of stress concentration, by forming an internal peripheral cylinder part radius of a ball pocket almost equal to a ball radius and also forming a clearance for lubrication by buckling deformation of the ball pocket. CONSTITUTION:A ball pocket spherical surface 21a has a spherical surface radius r1 almost equal to a ball 20b, to provide a clearance 21b serving as an oil reservoir in the bottom part. On the other hand, a calking type 22 is formed of 22a of a spherical surface radius r2, upper part plane 22b and an escape part 22c of a rod, to provide a surface of plastic deformation by 22a and 22b. Here, since a ball pocket 21c is deformed while buckled along the spherical surface 22a of a mold, a clearance 21d is generated between a ball and a ball pocket internal peripheral surface 21g in the vicinity of an equator of the ball 20b, with this clearance serving as an oil reservoir. The ball pocket internal peripheral surface 21g is formed by buckling into a curved surface smoothly connected to upper and lower part contact surfaces 21e, 21P, and generation of an inflection point, which is a cause of stress concentration, can be prevented.

Then, after the data are stored further in the buffer memory M2, and after the data are performed with error concealing EC to be outputted through a D/A converter DA. Quality of selective error concealing depends on the share and/or the appearance error rate of the buffer memory M3. When the memory M3 is filled up, an error concealing strategy required for many times, particularly larger scale interpolation algorithm is used.

Title: Lower noise preamplifier of ac type surface electrometer
Inventor: AOKI MINORU
IPC: G01R29/12
Filed: 1978-05-12
Abstract: PURPOSE: To prevent the generation of noise electric fields by shorting one of the input terminals of an operational amplifier and a metal case to become of the same potential.  
     CONSTITUTION: The AC current owing to the AC voltage corresponding to the electric field from the measuring object 8 detected by the detecting electrode 4 of an AC type surface electrometer is applied to the negative input terminal of the operational amplifier 5 of a preamplifier and is inversion-amplified, whereby the voltage corresponding to the measuring object electric field is generated. The positive input terminal of this amplifier 5 is held shorted to the metal case 6 of the amplifier 5 by a conductor 9, thus the positive input of the amplifier 5 and the case 6 become of the same potenital. Hence, the generation of the noise electric field between the negative input terminal to which the detecting current of the amplifier 5 is applied and the case 6 is prevented and the preamplifier is made lower in noise. The similar results may also be obtained even by letting the positive input terminal side be input and shorting the negative input terminal to the case.
