Title: Formation of quantum dot
Inventor: KAWAMOTO SHIGERU
IPC: H01L29/06
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To contrive to form quantum dots in high density and with good uniformity in a short period and to the same degree as the size of the quantum dots. SOLUTION: A metal structure 11 having an acute point as an STM chip and an AFM chip is made to approach the surface of a semiconductor substrate 10, and when an electrical pulse 12 is applied to this structure 11, fine projected matters 13 which are several tens to several nm in their diameter and height are formed on the surface of the substrate 10. After this, when a semiconductor ultrathin film layer 14 is grown epitaxially on the surface of the substrate including the projected materials 13, fine recesses 15 are formed directly over the projected materials 13. After this, when quantum dot raw materials 16 are fed to the surface of the ultrathin film layer 14 including the recesses 15, quantum dots 17 having a size of 10 nm or thereabouts are formed only in the parts of the recesses 15. In this method, since the STM chip can be moved to an accuracy of one nm, the two-dimensional array of the quantum dots in the period of several tens of um, that is, the short period of the same level as the size of the quantum dots is possible, whereby the quantum dots of a high density are obtained.

Title: Semiconductor memory
Inventor: ATSUMI SHIGERU
IPC: G11C16/06
Filed: 1990-07-05
Abstract: PURPOSE:To improve a noise margin and access time of a sense amplifier circuit by fastening the rise of a bias output without power supply voltage dependency in a bias potential output to suppress the high level of a bit line potential in the case of reading. CONSTITUTION:When any chip is not selected and a signal CE is set in an inactive state, for a bias circuit 11, a transistor 24 is turned to an OFF state and a power supply voltage Vcc is outputted as a bias potential VBIAS. When the chip is selected and the signal CE is turned to an active state, the bias potential is speedily lowered to a threshold voltage by transistors 22 and 23 since the transistor 24 is turned on and the bias potential is precharged to a high level in the case of no selection. On the other hand, since a bit line is prevented form being over charged by turning a transistor 65 for bit line potential clamp circuit to the ON state by the bias potential when the chip is not selected, a column decoder 64' controls all transistors 61 and 62 for column selection to an OFF state. Therefore, the noise margin and access time of the sense amplifier can be improved.

Title: Analysis of grain size distribution
Inventor: KANAMORI SHIGEO
IPC: G01N15/02
Filed: 1986-07-25
Abstract: PURPOSE:To improve the accuracy of the count value of respective fine particles by taking the natural logarithm of the frequencies of a grain size distribution and determining the average value and standard deviation of an estimated distribution from the section where the differences between the adjacent grain sizes form a straight line within the processing section (window) on the abscissa indicating grain sizes. CONSTITUTION:The natural logarithm of the grain size distribution is taken and the section where the differences between the adjacent grain sizes form the straight line within the window is found. The average value and standard deviation of the estimated distribution determined from such straight part are substd. with the theoretical distribution equation and the estimated distribution is determined. If the straight section is further found, the operation of determining the average value and standard deviation of the estimated distribution is repeated. The frequencies of the estimated distribution are determined and the original grain size distribution and estimated distribution are outputted to an output device if said section is not found. More specifically, the respective objective fine particle can be separated from noise, etc., and can be taken out and counted by determining the estimated distribution from the given grain size distribution. The accuracy and reliability of the count value of the respective fine particles are, therefore, improved.

Title: Malfunction preventing device
Inventor: TAKAKUWA SEI
IPC: H03K17/78
Filed: 1982-10-05
Abstract: PURPOSE:To transmit pulses with no malfunction due to a drop of power supply voltage at the input side, by invalidating the input signal when the power supply voltage has a drop after detecting the power supply drop at the input side. CONSTITUTION:When a switch 5 is closed, a photocoupler 1 conducts. Then L is supplied to a waveform shaping circuit 4, and the data is fed to an FF9 via an inverter 6. Then the terminal Q of the FF9 is set at H synchronously with the clock generated from a clock generating circuit 10, and a signal emerges at the output. In this case, if the power supply of the input side is normal, the circuit 10 is not reset since an FF8 is always on. Then a clock is supplied to the FF9. If the power supply voltage has a drop, a photocoupler 8 is turned off. Then the circuit 10 is reset to stop the clock. Thus no clock is fed to a clock terminal C of the FF9, and the signals fed during this period are invalidated. This device can prevent a malfunction due to a drop of the input power supply voltage.

Title: Voice coil bobbin
Inventor: INOUE TOSHIHIDE
IPC: H04R9/04
Filed: 1990-07-03
Abstract: PURPOSE:To obtain voice coil for speaker without anisotropy and with heat resistance, light weight, and high elasticity by using rod-like high polymer materials (PBT), (PBZT), and (PBO). CONSTITUTION:The rod-like high polymer material is composed of polybenzobisthiazole(PBT), polybenzthiazole(PBZT), or polybezoxazole(PBO). Since the characteristics of the essential advantage of the macromolecular material such as high elasticity, and high rigidity are used, the voice coil has large rigidity and the extremely small coefficient of thermal expansion of the material, and high heat resistance at the time of assembling it to the speaker. Thus the deformation of the bobbin and the stripping of the adhesion to a lead wire can be prevented and the defective magnetic air gap rubbing can be eliminated even when large power is inputted. Since specific gravity is small, the mass of the voice coil is decreased, electroacoustic conversion efficiency can be taken high, and the highest frequency of the reduced sound is high. Therefore, a reproduction sound area is broadly expanded.
