Inventor: SATO JUNJI
IPC: H01L29/786
Filed: 1991-03-15
Abstract: PURPOSE:To enhance the field effect mobility without depending upon the underlying layer by a method wherein the crystal nuclei are produced by annealing an a-Si thin film for solid growth on the surface side of the a-Si thin film. CONSTITUTION:An a-Si thin film 101 is laminated on a supporting layer 100 comprising an insulating amourphous material such as insulating amorphous material layer e.g. SiO2 by a low pressure CDV process, etc. Successively, hydrogen plasma is applied to the a-Si thin film. Next, the a-Si thin film is annealed for solid growth to be polycrystallized into poly-Si. At this time, the annealing step in hydrogen atmosphere can bring about the excellent effect of diffusing no nitrogen in the a-Si thin film 101 while enhancing the mobility of the thin film 101 after the solid growth step. Next, a gate electrode 103 is formed and an impurity element is ion-implanted using the gate electrode 103 as a mask to form a source region 104 and a drain region 105. Successively, an interlayer insulating film 107 is formed. Finally, the contact electrodes 108 between the source region 104 and the drain region 105 are formed.

IPC: G11B20/12
Filed: 1989-03-06
Abstract: PURPOSE:To minimize the loss of storage capacity of a recording medium by positioning defective spots, of the recording medium inside the gaps existing in front and near of a sector. CONSTITUTION:Information for executing format are written to the recording medium for one sector by a method determined in advance. These written information are read and when an error is found, the format is executed again. This formatting is repeated, while gradually increasing the number of writing bytes for the gaps to be written first, until the reading error disappears. Then, the number of bytes for an optimum gap 1 to avoid the defective spot and the number of bytes for a gap 3 in each sector are calculated and by using these values, one track is formatted. When the format is executed by such a method, a defective spots 10 are absorbed inside the gaps of the sector to be written at first. Accordingly, the storage capacity loss by the existence of the defective spots 10 is minimized.

Title: Generator of approximate function
Inventor: SAKATA SUEO
IPC: G06G7/28
Filed: 1980-04-18
Abstract: PURPOSE:To obtain a high-accuracy approximate function, by increasing the number of relational amplifiers for a broken line approximate function generator for control of an analog switch that sets the gain of an operational amplifier by a relational amplifier. CONSTITUTION:The values from small Ei1 to large Ein are set previously to the setters 6-1-6-N. When the input Ei becomes equal to either value of the setters 6-1-6-N, the corresponding relational amplifiers 1-1-1-N deliver the outputs V1- Vn to turn on the corresponding analog switches 3-0-3-N and then switch the corresponding gain setting volumes 7-0-7-N of operational amplifier 4. If the negative feedback ratio of amplifier 4 is set at (k), the output Eo is set as Eo= (R2/R1).(1/k)Ei. When the volume is set at is limit, k=1 is obtained. Accordingly the ratio (k) varies every time the input Ei becomes equal to the set value of setters 6-1-6-N. Thus the slope of the broken line varies for the output Eo. In this connection, the accuracy of approximate function can be increased higher as the number of comparators 1-1-1-N increases.
