Title: Semiconductor photodetective element
Inventor: AKETOSHI TOSHIMI
IPC: H01L31/10
Filed: 1990-05-14
Abstract: PURPOSE:To adjust a barrier layer in height and to enable an energy gas equivalent to the height concerned to function as a light absorbing region by a method wherein a thin semiconductor film forming a superlattice structure is specified in composition ratio. CONSTITUTION:When a semiconductor base material A (Al1-xGaxAs) and a semiconductor base material B (GaAs) are used to constitute a multi-quantum well superlattice structure, for instance the composition ratio of Ga to Al+Ga is set to 0.8. An energy gap ( Ec) equivalent to the height of a conduction band barrier layer becomes 0.6eV, and electrons positioned at the sub-level of a conduction well layer by incident light of certain wavelength are converted into free electrons traveling over the conduction band barrier layer. Therefore, x in AlxGa1-xAs is varied in the range of 0<x<1, whereby a semiconductor photodetective element maximal in sensitivity to light rays longer than light rays in wavelength equivalent to the energy gap of a semiconductor base material GaAs can be optionally obtained.

Title: Soft multilayered film
Inventor: KOGA SUSUMU
IPC: B32B27/00
Filed: 1994-06-02
Abstract: PURPOSE:To obtain a packaging material excellent in pinhole resistance and oxygen gas barrier properties by providing a nylon layer, a gas barrier layer, an adhesive layer, an ionomer layer and a layer of an ethylene/vinyl acetate copolyer with vinyl acetate content of a specific value or more. CONSTITUTION:Nylon generates no sudden softening even when a part of a film is strongly heated in the vacuum chamber part of a packaging machine for a skin pack at an initial stage and, since the film is relatively stretched as a whole, a perforation phenomenon is improved. Further, nylon has high mechanical strength and can reduce the thickness of the film to contribute to the enhancement of close adhesiveness. A multilayered film constituted of the outermost layer composed of nylon, a gas barrier layer, an adhesive layer, an ionomer layer and an ethylene/vinyl acetate copolymer layer with vinyl acetate content of 10wt.% or more is formed. The obtained soft multilayered film is excellent in oxygen gas barrier properties, sealability, flexibility and close adhesiveness.

Abstract: PURPOSE:To increase feedom in designing time-division signal synthesizing system, by shifting the frequency range of an input composite wave on a frequency axis by an integral multiple of a sampling frequency fs, and then making the obtained frequency range same as the passing band of an output-side filter. CONSTITUTION:The bands of input-side filters F1-Fn are so set that the frequency range of an input composite wave is less than ful and greater than fl1, and the band of an output-side filter F0 is so set that fl2<= (frequency band of input composite wave) +nfs<=fu2 (where n=+ or -1, + or -2...). Resonant transfer is performed by transferring electrostatic energy from signal sources in output- terminal capacitors C1-Cn of the input-side filters F1-Fn to the input-terminal capacitor C0 of the output-side filter F0. For this purpose, resonant switches RS1-RSn are closed nearly at intervals of Ts/n by pulses P1-Pn with short width. Then, the zero-cross point of the terminal voltage of the input-side capacitor of the filter F0 is detected by a zero-cross detector D.

After patterning the first polycrystalline silicon film 16, an interlayer insulation film 17 is formed and a second polycrystalline silicon film 18 is formed as a control gate. Since the impurity concentration in the first polycrystalline film 16 of the floating gate is controlled at most to 3X10<20>cm<-3> in a tunnel oxide film 15 formed in this way, the amount of charge that has passed becomes 8.2C/cm<2>. Since the dielectric breakdown strength becomes thereby higher than the conventional one, the life of the oxide film can be at least doubled.
